A Comparative Study of Peripartum Mental Health Disorders between COVID-19-infected and Non-infected during the Pandemic

Introduction: This study was done to compare the prevalence of mental health disorders between COVID-19-infected and non-infected mothers during the COVID-19 pandemic. The secondary objective was to find out the risk factors and long-term outcome of peripartum depression (PPD). Material(s) and Method(s): This was an observational and comparative study using a questionnaire-based direct interview, conducted in a tertiary hospital. After judging the inclusion and exclusion criteria, 842 subjects were selected between September 2020 to December 2020. The Edinburgh postnatal depression scale (EPDS) and COVID-19 anxiety scale (CAS) was used for evaluation of the mental health. Subjects with PPD were followed up for a year. Result(s): The mean age of the subjects was 24.8 +/- 3.9 years, 142 (16.8%) were confirmed COVID-19 positive. Overall, 317 (37.6%) had possible PPD (EPDS >=14) and 763 (90.6%) had peripartum anxiety (EPDS anxiety subscore >=4). While there was no significant difference in the prevalence of PPD (32.6% vs 39%, p = 0.12), peripartum anxiety was higher among COVID non-infected subjects (91.6% vs 86.6%, p = 0.04). Furthermore, COVID-19-related anxiety was higher among COVID-19-infected compared to the non-infected [17 (10-28) vs 15 (8-25), p = 0.00]. In multivariate analysis, medical comorbidities (p = 0.000), history of psychiatric illness (p = 0.002), domestic violence (p = 0.032) and obstetric complications (p = 0.000) were significant risk factors for PPD. Among the subjects who had PPD, only 35% still had depression after a year. Conclusion(s): This study provides an in-depth analysis of PPD and anxiety during the COVID-19 pandemic, the risk factors, and the long-term effects. Clinical significance: It highlights the importance of routine screening for perinatal mental health disorders and early psychiatric consultation when required.Copyright © The Author(s).

Contribution of the School of Biology of the University of Havana in the molecular diagnosis of SARS-CoV-2 at IPK

At the end of 2019, the existence and spread of a novel coronavirus called SARS-CoV-2, responsible of the disease COVID-19 was known worldwide. From the beginning, the Cuban governmental and health authorities drawn up epidemiological control strategies, in which the molecular diagnosis by real-time PCR was of paramount importance for the control of the disease in our country. A large number of young professionals and students from the School of Biology of the University of Havana joined this task. This paper deals with the main activities performed by the students related to the molecular diagnosis of SARS-CoV- 2 at the "Pedro Kouri" Institute of Tropical Medicine (IPK) in the first months of the pandemic in our country. The exercise of the profession in the implementation of the skills, and theoretical and practical knowledge;the acquisition of new knowledge;and the promotion of ethical and moral values such as solidarity, companionship, and joint work characterized this experience full of challenges and achievements.

Individuals with isolated congenital GH deficiency due to a GHRH receptor gene mutation appear to cope better with SARS-CoV-2 infection than controls.

PURPOSE: Several interactions exist between the GH/IGF axis and the immune system, including effects on innate immunity and humoral and cellular response. Acquired GH deficiency (GHD) has been recently proposed as a risk factor for severity of COVID-19 infections. However, acquired GHD is often associated to other factors, including pituitary tumors, surgery, radiotherapy, and additional pituitary hormones deficits and their replacements, which, together, may hinder an accurate analysis of the relationship between GHD and COVID-19. Therefore, we decided to assess the seroprevalence of SARS-CoV-2 antibodies and the frequency of symptomatic cases of COVID-19 in adults subjects with untreated isolated GHD (IGHD) due to a homozygous null mutation in the GHRH receptor gene. METHODS: A cross-sectional study was carried out in 27 adult IGHD subjects and 27 age- and gender-matched local controls. Interview, physical examination, bio-impedance, hematological and SARS-CoV-2 IgM and IgG antibodies were analyzed. RESULTS: There was no difference in the prevalence of positivity of anti-SARS-CoV-2 IgM and IgG antibodies between the two groups. Conversely, no IGHD individual had a previous clinical diagnosis of COVID-19 infection, while 6 control subjects did (p = 0.023). CONCLUSION: The production of anti-SARS-CoV-2 antibodies was similar between IGHD subjects due to a GHRH receptor gene mutation and controls, but the evolution to symptomatic stages of the infection and the frequency of confirmed cases was lower in IGHD subjects than in GH sufficient individuals.

Effect of covid-19 on hematological services

Aims & Objectives: To study the effect of COVID 19 on different hematological services. Patients/Materials & Methods: This observational study included 18 patients evaluated from June 2020 till September 2020 belonging to various age groups with a WHO defined hematological disease with laboratory-confirmed and symptomatic COVID-19. The primary outcome was mortality and evaluation of COVID-19 severity in different hematological diseases assessed on day 14 and 28. Patient characteristics, type of disease, symptomatology, HRCT findings and baseline qCRP levels were recorded and the need for oxygenation or in vasiveventilation with administration of various drugs and convalescent plasma and its consecutive effect in delay or nonadministration of chemotherapyevaluated. Results: A total of 140 hematology patients were admitted of which 18 patients (12.85%) were COVID-19 positive. 10 cases (55.55%) were of B cell Acutelymphoblasticleukemia (B-ALL), 3(16.66%) of acutemyeloidleukemia (AML) and 1 (5.55%) each of acute promyelocytic leukemia (APL), T cell acute lymphoblastic leukemia (TALL), T-Lymphoblastic lymphoma (T-LBL), Hodgkins lymphomaandaplasticanaemia. Majority of patients had mild COVID-19 infection (72.22%, n = 13), 4 cases (22.22%) were severely affected and 1 moderately affected. There was delay in administration in chemotherapy in 14 cases(77.77%), while 3 patients continued to receive chemotherapy during the viralillness. Survival at day 14 and 28 in B-ALL was 100%, survival in AML on day 14 and day 28 was 66.6%, survivalin T-ALL on day 14 was 100% and 0% on day 28, survivalin APL and T-LBL on day 14 was0%, survivalin Hodgkinslymphomaandaplasticanemia on day 14 and day 28 was 100%. Discussion & Conclusion: The results indicate that 12.85% cases were COVID-19 positive. 72.22% had mild COVID-19 infection and 22.22% had severe COVID-19 infection. The most common affected was B-ALL (55.55%). In 77.77% cases there was delay in administration of chemotherapy.

[Investigation of pathogenic agents causing acute respiratory tract infections in pediatric patients in a children's hospital assigned for case screening in Beijing during the outbreak of COVID-19].

Objective: To investigate the spectrum of pathogenic agents in pediatric patients with acute respiratory infections (ARI) during the outbreak of coronavirus infectious diseases 2019 (COVID-19). Methods: Three groups of children were enrolled into the prospective study during January 20 to February 20, 2020 from Capital Institute of Pediatrics, including children in the exposed group with ARI and epidemiological history associated with COVID-19 from whom both pharyngeal and nasopharyngeal swabs were collected, children in the ARI group without COVID-19 associated epidemiological history and children in the screening group for hospital admission, with neither COVID-19 associated epidemiological history nor ARI. Only nasopharyngeal swabs were collected in the ARI group and screening group. Each group is expected to include at least 30 cases. All specimens were tested for 2019-nCoV nucleic acid by two diagnostic kits from different manufacturers. All nasopharyngeal swabs were tested for multiple respiratory pathogens, whilst the results from the ARI group were compared with that in the correspondence periods of 2019 and 2018 used by t or χ(2) test. Results: A total of 244 children were enrolled into three groups, including 139 males and 105 females, the age was (5±4) years. The test of 2019-nCoV nucleic acid were negative in all children, and high positive rates of pathogens were detected in exposed (69.4%, 25/36) and ARI (55.3%, 73/132) groups, with the highest positive rate for mycoplasma pneumoniae (MP) (19.4%, 7/36 and 17.4%, 23/132, respectively), followed by human metapneumovirus (hMPV) (16.7%, 6/36 and 9.8%, 13/132, respectively). The positive rate (11.8%, 9/76) of pathogens in the screening group was low. In the same period of 2019, the positive rate of pathogens was 83.7% (77/92), with the highest rates for respiratory syncytial virus (RSV) A (29.3%, 27/92), followed by influenza virus (Flu) A (H1N1) (19.6%, 18/92) and adenovirus (ADV) (14.1%, 13/92), which showed significant difference with the positive rates of the three viruses in 2020 (RSV A: χ(2)=27.346, P<0.01; FluA (H1N1): χ(2)=28.083, P<0.01; ADV: χ(2)=7.848, P=0.005) . In 2018, the positive rate of pathogens was 61.0% (50/82), with the highest rate for human bocavirus (HBoV) (13.4%, 11/82) and followed by ADV (11.0%, 9/82), and significant difference was shown in the positive rate of HBoV with that in 2020 (χ(2)=6.776, P=0.009). Conclusions: The infection rate of 2019-nCoV is low among children in Beijing with no family clustering or no close contact, even with epidemiological history. The spectrum of pathogens of ARI in children during the research period is quite different from that in the previous years when the viral infections were dominant. MP is the highest positively detected one among the main pathogens during the outbreak of COVID-19 in Beijing where there is no main outbreak area.
