Far less damage than expected. While initial declines were observed, rebound was brisk as the pandemic progressed, with increases noted in the number tested, whether newly-initiated HIV or currently on ART, VL testing, and VLS throughout the period, demonstrating substantial HIV program resilience in the face of the COVID-19 crisis.

This work shows that more than eight million tons of pandemic-associated plastic waste have been generated globally, with more than 25,000 tons entering the global ocean. Most of the plastic is from medical waste generated by hospitals that dwarfs the contribution from personal protection equipment and online-shopping package material.

And even more. This groundbreaking study evaluated the body composition of 18 male football players from an Italian Serie A team by bioelectrical impedance. It is encouraging to see that after lockdown, no changes in body mass, body mass index, fat mass, fat-free mass, or total body water were seen.

A systematic review of major depressive disorder and anxiety disorders during the COVID-19 pandemic. Daily SARS-CoV-2 infection rates and reductions in human mobility were associated with increased prevalence of major depressive disorder. Females were more affected than males for major depressive disorder, and younger age groups were more affected than older age groups.

Less vegetables, more junk food: using a data set of 42,495 real food orders, this study suggests an association with unhealthier eating habits during the COVID-19 lockdown. The probability that the order contained vegetables decreased by 15%, while the probability of an order in the barbecue/fried food or beverage category increased by 11% and 4%, respectively. Of note, changes in eating habits persisted after lockdown measures were removed.

More junk food, but less infections: the 26% decrease in incidence of infections caused by pathogens transmitted commonly through food during 2020 was the largest single-year variation in incidence over the last 25 years in the US. Widespread public health interventions implemented to prevent SARS-CoV-2 transmission might have contributed to this decrease.

Beautifully put. After arguing that “mass shootings are rare events with causes that are not well understood”, the authors analyzed 2985 (!) mass shootings in the US, involving 3185 people killed and 12,547 injured. Bottom line: mass shootings are on the increase, possibly indicating that mass murderers may also be stressed these days (well, has anyone suggested gun laws?)

Most adolescents cope adequately with the pandemic conditions. However, they are at high risk becoming couch potatoes: this large cohort study including 2536 adolescents found that Norwegian adolescents starting high school during the COVID-19 year had lower odds of sports participation than their peers starting high school in preceding years, but no significant differences in depression symptoms, friendships, and physical health.

“Ever since the tobacco industry started marketing its products, it has attempted to hitch them to key trends and events. Adverts during World War One associated tobacco with victory. The industry would subsequently deploy the rhetoric of the suffragette movement with the “torches of freedom” campaign. Virginia Slims introduced the tagline “you’ve come a long way, baby” in the late 1960s, playing on the feminist themes of the era. “Today, we see the industry paying influencers on social media to push e-cigarettes, which they claim are harmless and cool, when in fact the whole point is to get a new generation addicted to nicotine. (…) As soon as COVID-19 arrived, they recognized the opportunity that the pandemic presented.”

Routine immunization services faced stark challenges in 2020, with the COVID-19 pandemic causing the most widespread and largest global disruption in recent history. Although the latest coverage trajectories point towards recovery in some regions, a combination of lagging catch-up immunization services, continued SARS-CoV-2 transmission, and persistent gaps in vaccine coverage before the pandemic still left millions of children under-vaccinated or unvaccinated against preventable diseases at the end of 2020, and these gaps are likely to extend throughout 2021.

This cross-sectional study suggests that the COVID-19 pandemic was associated with impaired mental health. The mental well-being and life satisfaction in adolescents in Austria were significantly lower in 2021 compared with 2018. However, owing to the online nature of the study, a self-selection bias toward higher participation of adolescents with a higher mental health burden may be possible.

One day, when humans will all be gone from earth, nature will quickly come out of its holes. Mountain lions first (according to this study where GPS collars were placed on six animals). Results: The drastic change in human behavior due to the Covid-19 pandemic had cascading effects on mountain lion habitat selection. Under normal circumstances, mountain lions strongly avoid urban areas. When human mobility declined by more than 50% during the Covid-19 associated lockdown, mountain lions relaxed their fear of the urban edge during the lockdown.

A decrease in influenza was already seen following relatively modest control measures, including mask-wearing recommendations among only ill or symptomatic individuals. Influenza remained nearly absent for the remainder of 2020. International travel restrictions likely contributed to this. For enterovirus/rhinovirus and adenovirus, reductions were only seen after lockdown, and these viruses rebounded earlier than others. Continued mandatory mask wearing did not appear to prevent this.

MMWR 11 June 2021. https://www.cdc.gov/mmwr/volumes/70/wr/mm7024e1.htm?s_cid=mm7024e1_w

During February 21–March 20, 2021, suspected suicide attempt ED visits were 50.6% higher among girls aged 12–17 years than during the same period in 2019; among boys aged 12–17 years, suspected suicide attempt ED visits increased 3.7%.

Crime largely decreased around the globe during COVID-19 stay-at-home orders, but with substantial variation across cities and types of crime. Property-based crimes decreased substantially, but homicide was relatively unchanged. Meta-regression results showed that more stringent restrictions over movement in public space were predictive of larger declines in crime.

In this cohort study from Michigan, a 14% reduction in pregnancy episode initiation was observed, probably due to a decrease in conceptions that followed the March 15 mandated COVID-19 pandemic societal shutdown. Prospective modeling of pregnancies currently suggests that a birth volume surge can be anticipated in summer 2021.

In this large study including 27 laboratories from 26 countries and territories, all laboratories experienced a significant and sustained reduction in invasive diseases due to S. pneumoniae, H. influenzae, and N. meningitis in early 2020. By contrast, no significant changes in the incidence of invasive S. agalactiae infections were observed. The incidence of reported S. pneumoniae infections decreased by 68% at 4 weeks and 82% at 8 weeks following the week in which significant changes in population movements were recorded.

Was there an early effect of the COVID-19 pandemic on suicide rates around the world? Probably not. In high-income and upper-middle-income countries, suicide numbers have remained largely unchanged or declined in the early months of the pandemic compared with the expected levels based on the pre-pandemic period.

Less accidents (for a few weeks) but more gunshots? In this retrospective cohort study of 6777 trauma admissions in Los Angeles County from January 1 to June 7, 2020, overall volume transiently decreased but quickly returned to baseline. Mechanisms of injury were significantly different, with a steady increase in admissions for “penetrating” injuries (in other words: mainly gunshots).

A large number of outbreaks of acute upper respiratory tract infections (URTIs), likely rhinovirus infections, were identified in October–November 2020 in reopened primary schools, secondary schools, kindergartens, childcare centers, and nursery schools in Hong Kong; these outbreaks led to further territory-wide school dismissals for younger children. Increased susceptibility to rhinoviruses during prolonged school closures and dismissals for coronavirus disease and varying effectiveness of nonpharmaceutical interventions may have heightened transmission of cold-causing viruses when school attendance resumed.

Using interrupted time series analysis of testing for viral respiratory pathogens, this study found that statistically significant lower rates of common community respiratory viruses appeared to be associated with a shelter-in-place order during the coronavirus pandemic. Decreases were most pronounced for influenza (93%) and for rhinovirus or enterovirus (81%). Lower rates of post-exposure viral activity were seen for respiratory syncytial virus, parainfluenzavirus, coronaviruses, and adenoviruses, however, these associations were not statistically significant.

Facing the clinical imperative to minimise patient exposure to hospital facilities to mitigate against the risk of nosocomial acquisition of COVID-19, the authors switched their patients with inflammatory bowel diseases (IBD) from intravenous to subcutaneous infliximab. Experiences are encouraging: in 31 IBD patients, this strategy appeared safe and enabled patients requiring infliximab to have home treatment self-administered at their convenience on the day of dose instead of having to attend a scheduled appointment at the hospital for an infusion.

During the COVID-19 quarantine period, more than 20% of adolescents had anxiety and depression. This is the result of an online questionnaire (using convenient sampling method) with 7890 teenagers from Wuhan. The prevalence was 21,7% (n = 1708) for anxiety and 24,6% (n = 1941) for depression (HADS subscale score > 7). Long-term home restrictions might have adverse effects on mental health of adolescents because of a sharp change of lifestyle and various other stressors like fear of infection, frustration, and boredom.

In Japan, monthly suicide rates declined by 14% during the first 5 months of the pandemic (February to June 2020). This could be due to a number of complex reasons, including the government’s generous subsidies, reduced working hours and school closure. By contrast, monthly suicide rates increased by 16% during the second wave (July to October 2020), with a larger increase among females (37%) and children and adolescents (49%).

Eva Morris et al.

Pandemic COVID-19 waves lead to a sustained reduction in the number of people referred, diagnosed, and treated for colorectal cancer. As compared to the monthly average in 2019, in April 2020 there was a 63% reduction (from 36.274 to 13.440) in the monthly number of 2-week referrals for suspected cancer and a 92% reduction in the number of colonoscopies (from 46.441 to 3484).

Recent studies have shown that patients with chronic liver disease (CLD) in general, and especially those with decompensated cirrhosis and alcohol-related liver disease, are at higher risk COVID-19-related mortality. In this multi-center US cohort study, Renumathy Dhanasekaran, Nia Adeniji and colleagues included 909 patients with CLD and COVID-19 from 21 US centers. They show that non-Hispanic Blacks (NHB) and Hispanics are disproportionately represented in patients with CLD who acquire COVID-19. Both non-Hispanic Blacks and Hispanics had lower household income, lower rates of private insurance, and Hispanics had higher rates of being uninsured. Additionally, the authors show that both NHB and Hispanics had a higher likelihood of living in multifamily housing and in neighborhoods with higher rates of poverty and overcrowding than non-Hispanic Whites.

Adolescent substance use is a significant and largely undertreated public health concern. The COVID-19 pandemic has exacerbated many pre-existing risk factors for adolescent substance use, such as early life stress, social isolation, school connections, and boredom. Here, Dana Sarvey and Justine Welsh give a short overview of changing risk and protective factors for substance use and potential opportunities during the pandemic. They recommend that practitioners should consider any and all means of reaching out to these youth and their families and addressing other co-occurring psychiatric symptoms, such as depression and anxiety.

Cumulative counts of domestic crimes were higher during the COVID-19 period of 2020 than in the preceeding two years suggesting increased occurrence of domestic violence, especially during shelter-in-place orders. This is the result of an analysis of 30 weeks of crime data collected from the Atlanta Police Department (APD). Dabney Evans, Shila René Hawk and Carrie Ripkey found that a spike in domestic crimes was recorded after city and statewide shelter-in-place orders. The authors summarize that the “co-occurring pandemics of COVID-19 and domestic violence come amidst a period of racial justice reckoning in the United States and that both have a disproportionate impact on Black, Indigenous, and People of Color. As the country grapples with how to deal with health and safety concerns related to the pandemic, and the unacceptable harms being perpetrated by police, a public health approach is strongly warranted to address both universal health care and violence prevention.”

Head and neck cancer surgery in the COVID‐19 era appears safe even when surgery is prolonged and complex. This is the result of an international, observational cohort study comprised of 1137 consecutive patients with head and neck cancer undergoing primary surgery with curative intent in 26 countries. The overall 30‐day mortality was 1.2%. Twenty‐nine patients (3%) tested positive for severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) within 30 days of surgery; 13 of these patients (44.8%) developed severe respiratory complications, and 3 (10.3%) died. There were significant correlations with an advanced tumor stage and admission to critical care.

Maintaining surgical oncologic activity in the era of the COVID-19 pandemic seems safe and feasible, with low postoperative morbidity and mortality. The authors collected data on thoracic malignancy surgeries from January 1 to April 30, 2020, including patients from high-volume thoracic surgery departments in Nancy, Strasbourg, Freiburg, Milano, Torino and Montreal. In the cohort of 731 patients, 9 cases (1.2%) of COVID-19 were confirmed by PCR, including 5 in-hospital contaminants. The total number of deaths was 22 (3%). Only one death was related to COVID-19 (0,14%).

In this meta-analysis, the authors assessed outcomes of 50.123 patients from 10 studies. Did the analyzed data show that acute and timely medical care of these patients had been maintained during the pandemic in most countries? Yes, they did. Consequently, despite a significant reduction in overall admission rates of patients with STEMI during the COVID-19 pandemic (incidence rate ratio = 0.789, 95% CI 0.730 to 0.852, I2=77%, p < 0.01), there was no significant difference in hospital mortality (OR = 1.178, 95% CI 0.926 to 1.498, I2=57%, p = 0.01) compared with patients with STEMI admitted before the outbreak.

Post-partum depression, the most common complication of childbearing, is a prevalent, cross-cultural disorder. Even in the best environments, the period following childbirth represents a time of heightened stress and vulnerability for most, if not all, new parents. In this study of 516 post-partum patients, Michael Silverman et al. now demonstrate a differentiated response in the post-partum mood of those living in New York City during the COVID-19 pandemic… based on socioeconomic status! While those in areas with higher socioeconomic status (SES) demonstrated no change in post-partum mood after implementation of social restrictions in New York, those living in lower SES expressed improved mood over the same time period.

Self-harm often precedes suicide and can be used as a proxy outcome to identify how the pandemic has affected population mental health. As yet, there is no indication that the pandemic has caused self-harm rates to increase in the UK. The authors cite a study of 1500 general practices in the UK which found that the recorded incidence of self-harm was 38% lower in April, 2020, than the rate expected on the basis of previous years (Carr MJ, Steeg S, Webb RT, et al). Primary care contact for mental illness and self-harm before, during and after the peak of the COVID-19 pandemic in the UK: cohort study of 13 million individuals. Lancet Public Health (in press)).

The authors leveraged a large, national US EMS database to characterize emergent trends in overdose mortality fueled by the pandemic. They describe a large-magnitude, national surge in overdose-related cardiac arrest during the initial months of the COVID-19 epidemic in the US. Peak rates in May 2020 were more than double the baseline from 2018 and 2019, and overall 2020 values were elevated by approximately 50%. Results suggest that the fallout from the COVID-19 pandemic—perhaps especially social isolation—is sharply accelerating fatal overdose trends.

Patients with COVID-19 are at increased risk of cardiac complications including cardiac arrest. Of admitted patients, almost 30% may have evidence of myocardial injury with mortality among hospitalized patients as high as 70%. The resuscitation of these patients requires a conscious effort to minimize the spread of SARS-CoV-2. The authors present a best-practice model based on four guiding principles: (1) reduce the risk of exposure to the entire health care team; (2) decrease the number of aerosol-generating procedures; (3) use a small resuscitation team to limit potential exposure; and (4) consider early termination of resuscitative efforts.

Interruptions of TB control programs could potentially prolong diagnostic delays and worsen TB treatment outcomes. In addition, the upcoming economic recession could lead to a reduction of income and a rise in unemployment rates in TB-affected households. All of these factors increase the risk of TB incidence and the economic impact on TB-affected households.

In this prospective clinical trial, the authors evaluated the efficacy of triage to identify COVID‐19 among patients with cancer. Of 562 enrolled patients, 6 (1%) were diagnosed with COVID‐19, of whom 4 (67%) had the disease detected through telehealth triage, and 2 patients (33%) without suspect symptoms at triage had the disease detected later. The authors conclude that telehealth triage was helpful in detecting suspect patients and to keep a COVID‐19–free cancer center. The overall incidence of COVID‐19 diagnosis (1%) and antibody positivity (13%) in patients with suspect symptoms was similar to that observed in the general population.

Rheumatology (Oxford). 2020 Dec 4:keaa855. PubMed: https://pubmed.gov/33271595. Full-text: https://doi.org/10.1093/rheumatology/keaa855

The risk of all-cause death is more prominently heightened during COVID-19 among people with rare autoimmune rheumatic diseases (RAIRD) than among the general population. This is a result of an analysis which included 168.691 people with a recorded RAIRD diagnosis alive on 01/03/2020. The age-standardized mortality rate (ASMR) among people with RAIRD was 1.44 times higher than the average ASMR during the same months of the previous 5 years, whereas in the general population of England it was 1.38 times higher. The authors suggest quantifying how much risk is due to COVID-19 and how much is due to a disruption to healthcare services.

Increase in Hospital-Acquired Carbapenem-Resistant Acinetobacter baumannii Infection and Colonization in an Acute Care Hospital During a Surge in COVID-19 Admissions — New Jersey, February–July 2020. MMWR Morb Mortal Wkly Rep. ePub: 1 December 2020. Full-text: http://dx.doi.org/10.15585/mmwr.mm6948e1

Carbapenem-resistant Acinetobacter baumannii (CRAB) causes health care–associated infections that are challenging to contain and often linked to infection prevention and control breaches. What a mess: colleagues from a New Jersey hospital report on a cluster of 34 CRAB cases (26 isolates harbored the gene encoding the OXA-23 carbapenemase) that peaked during a surge in COVID-19 hospitalizations. The authors conclude that strategies to preserve continuity of care led to deviations in IPC practices; CRAB cases decreased when normal operations resumed.

Richard Armitage and Laura B Nellums comment on the number of antibiotic prescriptions made in UK general practice between April 1, and Aug 31, 2020. The number was 15% lower than in the corresponding period in 2019. However, given the decrease in absolute number of appointments over this time, this number of prescriptions was 7% higher than expected, supporting evidence that antibiotic prescribing rates are higher in remote consultations than during in-person appointments.

This international cohort study GENEVA investigated the outcomes of bariatric and metabolic surgery (BMS) performed in 2116 adults (≥ 18 years) between May 1 and July 10 from 133 hospitals in 38 countries. Overall, 30-day morbidity and mortality following BMS during the COVID-19 pandemic with locally appropriate perioperative COVID-19 protocols in place seemed to be similar to pre-pandemic levels. Of the ten patients with symptomatic post-operative COVID-19, none needed ventilation and none died.

The pandemic has had considerable impact on testing for HIV, viral hepatitis and STIs in the WHO European Region. Preliminary results show that 95% of respondents from 34 countries reported testing less than half the expected number of people during the first months of the COVID-19 pandemic between March and May 2020. This continued, although to a lesser degree, between June and August 2020, when measures were less strict in most countries.

Lancet Oncol 2020, published 27 November. Full-text: https://doi.org/10.1016/S1470-2045(20)30619-7

During the 2020 spring lockdown and immediately thereafter, there was an important reduction in systemic anti-cancer treatment initiation in England: 32% in April and 10% in May. In June, the number of registrations for new systemic anti-cancer treatments increased by 15% compared to the 6 pre-COVID months (September, 2019, to February, 2020). James Clark et al. recommend continuing to assess the effects of delaying treatment initiation for advanced cancers and neoadjuvant therapies.

Good news (for dogs) from Israel: the stricter the social isolation became during the COVID-19 pandemic, the greater the interest in dog adoption. Dog abandonment has decreased and the rates of dog adoptions improved significantly; the demand for adoptable dogs and the requests to serve as foster families increased significantly, and accordingly, the length of stay of dogs at the shelter was significantly shorter.

A total of 6609 patients underwent primary percutaneous coronary intervention (PPCI) in 77 centers, located in 18 countries. In 2020, during the pandemic, there was a significant reduction in PPCI as compared with 2019 (incidence rate ratio: 0.81; 95% confidence interval: 0.78 to 0.84). Furthermore, the pandemic was associated with a significant increase in “door-to-balloon” and total ischemia times, which may have contributed to higher mortality during the pandemic.

Do suicide rates increase during infectious disease outbreaks? Probably not (at least in Australia). In this study, analyzing suspected suicide rates in 2020 relative to 2015–19 to assess any early effects of the COVID-19 pandemic in Queensland, no evidence of a change in suspected suicide rates was seen.

Good question. We don’t know yet. After summarizing various determinants that may result in either an increase or, inversely, a decrease in antimicrobial resistance (AMR), the authors found them to be balanced. The truth is that the impact of the COVID-19 pandemic on AMR will only become clear in the coming months and years as data gradually become available. Changes in AMR will most likely vary depending on the setting—e.g., ICUs vs other hospital units, hospital vs community settings—and possibly between countries.

What is the association between the SARS-CoV-2 pandemic and out-of-hospital cardiac arrest (OHCA) outcomes in the US? This large registry study of 19,303 cases in 2019 and 2020 showed that the return of spontaneous circulation (ROSC) for OHCA was 18% lower overall than before the pandemic. Although the decrease was more prominent in counties most affected by the COVID-19 pandemic, lower rates of sustained ROSC and higher rates of termination of resuscitation were also observed in counties with low COVID-19 mortality rates. Delays in seeking medical care during the lockdown may not entirely explain the findings. The authors speculate that the interim recommendations for emergency medical service during this pandemic (for protecting frontline health care workers from unnecessary exposure) may also have decreased the likelihood of a successful resuscitation.

Lockdown causes domicile discord which in turn causes more penetrating trauma? Jose Pascual, Hatem Abdallah and colleagues tested the hypothesis that intentional injury might have increased during stay-at-home-orders (SAHO) and assessed injury patterns from 6 weeks pre- to 10 weeks post- statewide stay-at-home order. 357 and 480 trauma patients presented pre- and post-SAHO, respectively. Pre- and post- groups demonstrated differences in sex, age, and race. Post-SAHO mechanism of injury (blunt vs. penetrating) revealed more intentional injury.

When you sleep, your smartphone is taking notes and you may end up in a scientific publication. Here Paul Lee and colleagues utilized a large crowdsourced database (Sleep as Android) and analyzed the (your?) sleep behavior of 25,217 users with 1,352,513 sleep records between 1st January and 29th April 2020 in 16 European countries (Germany, United Kingdom, Spain, France, Italy, the Netherlands, Belgium, Hungary, Denmark, Finland, Norway, Czech, Sweden, Austria, Poland, and Switzerland) and in the US. The unsurprising result: during lockdown, people delayed their bedtime and slept longer than usual.

Forty-four papers, involving a total of 54,231 participants from 13 countries, contributed to this systematic review and meta-analysis of sleep problems during COVID-19. The global pooled prevalence rate of sleep problems among all populations was 35,7%. COVID-19 patients appeared to be the most affected group, with a pooled rate of 74,8%. Healthcare workers and the general population had comparative rates of sleep problems with rates of 36,0% and 32,3%, respectively.

Among 5102 samples of virus taken from Danish patients since June, five infection clusters affecting 214 people involved mink variant virus. One of these, known as cluster 5, seems to be a problematic variant which could be less susceptible to some antibodies and/or vaccines (unproven). This variant has been detected with four simultaneous changes in the genes for the Spike protein (for nerds: H69del/V70del, Y453F, I692V and M1229I) and has affected 11 people in North Jutland. Conclusion: 17 million minks will be culled.

Non-pharmaceutical interventions (NPIs) implemented to slow the spread of SARS-CoV-2 have led to the decline in the incidences of highly transmissible respiratory infections. This is the result of a study by Ji-Man Kang, Kyungmin Huh and colleagues from the Children’s Hospital, Yonsei University College of Medicine, Seoul. Comparing the period February–July 2020 to the previous 4 years, the authors found that the incidences of chickenpox and mumps were significantly lower than in the prediction model (chickenpox: 36%, mumps: 63%).

No damage in this area: Compared with the previous year, the cumulative numbers of deceased organ donors and transplants showed no significant reduction in Germany. Kidney transplantation numbers were stable, while the numbers of heart, lung, and liver transplantations from deceased donors even increased from January to April, 2020, when compared with the same period of the previous year. In contrast, transplant activities in Italy and Spain were reduced by 30–50%.

We have eagerly awaited this news for decades: spectators can significantly contribute to determine the dynamics and the outcomes of professional football matches (home advantage and referee bias are two well-documented phenomena in professional sports). COVID-19 has made it possible: focusing on the first and second divisions of the top four UEFA countries, the authors analyzed 841 matches behind closed doors during the pandemic. This extremely important work revealed that observed frequencies for home victories, draws and away victories were significantly different from the expected frequencies calculated based on the last three complete seasons with spectators. The absence of a referee bias in favor of the home teams for yellow cards indicated that this factor might be particularly affected by the presence/absence of social pressure by spectators. Various parameters were considered, and the analyses revealed a reduction of home advantage and the absence of referee bias. They´ll walk alone now.

This nation-wide survey study of 69,054 students from France who experienced quarantine found high prevalence rates of severe self-reported mental health symptoms, including suicidal thoughts (11%), severe distress (22%), high level of perceived stress (25%), severe depression (16%), and high level of anxiety (28%). Among risk factors identified, female or nonbinary gender, problems with income or housing, history of psychiatric follow-up, symptoms compatible with COVID-19, social isolation, and low quality of information received were associated with altered mental health. Main limitation is that the population represented only 4.3% of students contacted and that self-selection bias may have altered the results. However, they are suffering.

A preview of what cardiology departments might see in the coming autumn and winter months 2020/2021. The authors analyzed the impact of COVID-19 on changes in cardiac procedure activity in England. Compared to the monthly averages (March-May) in 2018/2019, there was a deficit of 45,501 procedures between 1st January and 31st May 2020. Cardiac catheterization and device implantations were the most affected in terms of numbers (n = 19,637 and n = 10,453). No difference in 30-day mortality was observed between pre-COVID and COVID time-periods for all cardiac procedures except cardiac catheterization and cardiac device implantation.

Who suffers the most? While many countries prepare for a second lockdown, this study took a look on the psychological consequences during the first wave, performing interviews with a total of 1226 parents via a demographic questionnaire. Seventeen percent reported significant parenting-related exhaustion and most parents reported a clinically alarming level of distress. Multiple regression analyses showed that greater parenting-related exhaustion was predicted by psychological distress, lower parental resilience, motherhood, fewer perceived social connections, and being single, as well as having a child with special needs, having a large number of children, and having younger children.

In many countries, lockdowns exacerbate the risk of food insecurity and intimate partner violence. Here Sant-Rayn Pasricha, Jena Derakhshani Hamadani and colleagues analyze the impact lockdown orders on women and their families in rural Bangladesh. They randomly selected and invited the mothers of 3016 children to participate in the study, 2424 of whom provided consent. Almost all women reported a reduction in paid work for the family. Median monthly family income fell from US$212 at baseline to $59 during lockdown, and the proportion of families earning less than $1·90 per day rose from almost 0% to 47%. Before the pandemic, 5.6% and 2.7% experienced moderate and severe food insecurity, respectively. This increased to 36.5% and 15.3% during the lockdown.

Patients with cancer have been reported to be at increased risk of infection with SARS-CoV-2 and a more severe disease course. Here Gary Middleton, Lennard Lee and colleagues compare cancer patients with and without COVID-19 and analyses the effect of tumor features (primary subtype and stage) and patient demographics (age and sex) on the risk and trajectory of COVID-19 disease. Some results:

  1. The all-cause case–fatality rate in patients with cancer after SARS-CoV-2 infection was significantly associated with increasing age, rising from 0.10 in patients aged 40–49 years to 0.48 in those aged 80 years and older.
  2. Patients with hematological malignancies (leukemia, lymphoma, and myeloma) had a more severe COVID-19 trajectory compared with patients with solid organ tumors.
  3. Patients with hematological malignancies who had recent chemotherapy had an increased risk of death during COVID-19-associated hospital admission (odds ratio 2.09).

From August 2019 to February 2020, 2,807 cases of EVALI (e-cigarette, or vaping, product use-associated lung injury) were reported to the CDC, including 68 deaths. Symptoms of EVALI may overlap with those of some infectious respiratory diseases, including COVID-19. This editorial highlights current knowledge and how the effects of vaping might now be colliding with the risk of COVID-19. Several experts have asked for e-cigarettes to be withdrawn from the market during the pandemic.

Interesting: The number of measles cases declined in the EU and UK in 2020. Reported cases to The European CDC decreased from 710 to 54 between January and May. However, according to the authors, under-diagnoses and under-reporting during the COVID-19 pandemic should be ruled out before concluding that reduced measles circulation is due to social distancing and any community control measures taken to control COVID-19.

Out of fear of contracting SARS-CoV-2, large numbers of patients avoided hospitalization during the COVID-19 pandemic. After analyzing 15,244 hospitalizations involving 14,724 patients with acute myocardial infarction, Tyler Gluckman and colleagues found that patients hospitalized for acute myocardial infarction during the early COVID-19 period had an increased observed/expected mortality ratio which was associated disproportionately with patients with ST-segment elevation myocardial infarction (STEMI).

Kaufman HW, Chen Z, Niles J, Fesko Y. Changes in the Number of US Patients with Newly Identified Cancer Before and During the Coronavirus Disease 2019 (COVID-19) Pandemic. JAMA Netw Open 2020;3(8):e2017267. Full-text: https://doi.org/10.1001/jamanetworkopen.2020.17267

During and after lockdowns, people go into hibernation mode, but cancer does not. Now Harwey Kaufman and colleagues report a cross-sectional study about patients across the United States who received clinical laboratory testing related to any of 6 cancer types (i.e., breast, colorectal, lung, pancreatic, gastric, and esophageal). Each patient was counted once, at the first instance of a cancer-related ICD-10 code. The authors compared 258,598 patients from the baseline period (January 6, 2019, to February 29, 2020) with 20,180 patients from the COVID-19 period (March 1 to April 18, 2020). During the pandemic, the weekly number of newly identified patients fell 46.4% (from 4310 to 2310) for the 6 cancers combined, with significant declines in all cancer types, ranging from 24.7% for pancreatic cancer (from 271 to 204; p = 0.01) to 51.8% for breast cancer (from 2208 to 1064; p < 0.001). The authors anticipate that a delay in diagnosis will likely lead to presentation at more advanced stages and poorer clinical outcomes.

How prevalent is burnout among frontline health care workers (HCWs) during the COVID-19 pandemic? Takahiro Matsuo and colleagues conducted an online cross-sectional survey among HCWs at a tertiary hospital in Tokyo which had among the highest numbers of patients with COVID-19 in Japan. Among the final sample of 312 HCW’s, the burnout prevalence was 31.4% (98 of 312). Nurses: 59/126 (46.8%); radiological technologists: 8/22 (36.4%); pharmacists: 7/19 (36.8%).

Mekaoui N, Razine R, Bassat Q, et al. The Effect of COVID-19 on Paediatric Emergencies and Admissions in Morocco: Cannot See the Forest for the Trees? J Trop Pediatr 2020, published 1 August. Full-text: https://doi.org/10.1093/tropej/fmaa046

Where are the sick Moroccan children normally brought to the emergency department? When Nour Mekaoui and colleagues from the Rabat Children’s Hospital, Morocco, compared the number of pediatric consultations (< 16 years) in the emergency department from 16 March to 15 April 2020 with the number of consultations of the same period in the preceding year, they discovered that the number of overall consultations decreased by 74% between the two periods (4232 vs. 1110; p < 0.005). Even the the number of hospitalizations declined (811 in 2019 vs. 471 in 2020, a 41.9% reduction, p < 0.005; see figure). The authors are worried: Where did these severely ill patients go? Might we anticipate a new wave of serious non-COVID-19 pediatric admissions?

Kansagra AP, Goyal MS, Hamilton S, Albers GW. Collateral Effect of Covid-19 on Stroke Evaluation in the United States. N Engl J Med 2020; 383:400-401. Full-text: https://doi.org/10.1056/NEJMc2014816

Any decrease in care for patients with ischemic stroke may be consequential because timely treatment may decrease the incidence of disability. The authors compare the mean daily counts per hospital of patients in the pre-pandemic 29-day epoch from February 1, 2020, through February 29, 2020, with the mean daily counts per hospital of patients in a 14-day period during the early pandemic, from March 26, 2020, through April 8, 2020. They found a decrease of approximately 39% in the numbers of patients who received evaluations for acute stroke between two recent periods in U.S. hospitals. The decrease in the use of stroke imaging from the pre-pandemic epoch to the early-pandemic period was seen across all ages, sexes, and stroke severity subgroups.

Maringe C, Spicer J, Morris M, et al. The impact of the COVID-19 pandemic on cancer deaths due to delays in diagnosis in England, UK: a national, population-based, modelling study. Lancet Oncology, published: July 20, 2020. Full-text: https://doi.org/10.1016/S1470-2045(20)30388-0

During the UK COVID lockdown, cancer screening was suspended, routine diagnostic work deferred, and only urgent symptomatic cases were prioritized for diagnostic intervention. The authors estimate the impact of diagnostic delays over a 12-month period from the commencement of physical distancing measures, on March 16, 2020, up to 1, 3, and 5 years after diagnosis. They expect an increase in the number of avoidable cancer as a result of the COVID-19 pandemic:

Breast cancer: 281–344 additional deaths (increase: 7.9–9.6%)

Colorectal cancer: 1445–1563 additional deaths (15.3–16.6%)

Lung cancer: 1235–1372 additional deaths (4.8–5.3%)

Esophageal cancer: 330–342 additional deaths (5.8–6.0%)

The COVID pandemic has caused people to delay medical care, even for life-threatening conditions. The authors analyzed data of 532 children and adolescents with newly diagnosed type 1 diabetes from 216 German diabetes centers (median age: 9.9 years). Diabetic ketoacidosis was present in 238 patients (44.7%) and severe ketoacidosis in 103 patients (19.4%). During the same periods in 2019 and 2018, the frequency of diabetic ketoacidosis was significantly lower (2019: 24.5%; 2018: 24.1%). The incidence of severe diabetic ketoacidosis was also significantly lower (2019: 13.9%; 2018: 12.3% in 2018). Children younger than 6 years had the highest risk.
