High anti-SARS-CoV-2 seroprevalence among unvaccinated mother-child pairs from a rural setting of north-eastern Tanzania during the second wave of COVID-19.

Background: The reported infection rates, and the burden of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) in low- and middle-income countries, including sub-Saharan Africa, are relatively low compared to Europe and America, partly due to limited testing capabilities. Unlike many countries, in Tanzania, neither mass screening nor restrictive measures such as lockdowns have been implemented to date. The prevalence of SARS-CoV-2 infection in rural mainland Tanzania is largely unknown. Methods: Between April and October 2021, we conducted a cross-sectional study to assess anti-SARS-CoV-2 seroprevalence among mother-child pairs (n=634 children, n=518 mothers) in a rural setting of north-eastern Tanzania. Findings: We found a very high prevalence of anti-SARS-CoV-2 antibody titres with seroprevalence rates ranging from 29% among mothers and 40% among children, with a dynamic peak in seropositivity incidence at the end of July/early in August being revealed. Significant differences in age, socioeconomic status and body composition were associated with seropositivity in mothers and children. No significant associations were observed between seropositivity and comorbidities, including anaemia, diabetes, malaria, and HIV. Interpretations: The SARS-CoV-2 transmission in a rural region of Tanzania during 2021 was high, indicating a much higher infection rate in rural Tanzania compared to that reported in the UK and USA during the same period. Ongoing immune surveillance may be vital to monitoring the burden of viral infection in rural settings without access to molecular genotyping where a load of communicable diseases may mask COVID-19. Surveillance could be implemented in tandem with the intensification of vaccination strategies.

An Exercise Prescription as a Novel Management Strategy for Treatment of Long COVID.

Mechanisms causing the post-acute sequelae of SARS-CoV-2 (long COVID) remain elusive, but the clinical phenotype is consistent with cardiac deconditioning. We report a case series of patients with long COVID whose symptoms improved/resolved with exercise and present exercise training as a novel therapeutic strategy for management of long COVID syndrome.

Erythema multiforme as a presentation of COVID-19: Case Illustrated format.

COVID-19 is now an established morbidity across races, regions and clinical risks around the world. From its first detection in Wuhan city-China in 2019 to the recent breakthrough of approved vaccines, that are determinants and deterrents and gradually becoming apparent. The phenotype of its presentation however is both variable and challenging especially. For those presenting with unique skin dermatosis such as erythema multiforme. Case report Our case is on a 36 year- old gentleman who presented to the hospital complaining, initially of only urticarial rash (later established to be erythema multiform), which improved with symptomatic treatment. He was discharged, only to be re-admitted a week later with exacerbation of the former cutaneous manifestation, accompanied by fever and gastrointestinal symptoms. He ultimately made complete recovery and was discharged home.

The Impact of COVID-19 On Comorbidities: A Review Of Recent Updates For Combating It.

Coronavirus disease is caused by the SARS-CoV-2 virus. The virus first appeared in Wuhan (China) in December 2019 and has spread globally. Till now, it affected 269 million people with 5.3 million deaths in 224 countries and territories. With the emergence of variants like Omicron, the COVID-19 cases grew exponentially, with thousands of deaths. The general symptoms of COVID-19 include fever, sore throat, cough, lung infections, and, in severe cases, acute respiratory distress syndrome, sepsis, and death. SARS-CoV-2 predominantly affects the lung, but it can also affect other organs such as the brain, heart, and gastrointestinal system. It is observed that 75 % of hospitalized COVID-19 patients have at least one COVID-19 associated comorbidity. The most common reported comorbidities are hypertension, NDs, diabetes, cancer, endothelial dysfunction, and CVDs. Moreover, older and pre-existing polypharmacy patients have worsened COVID-19 associated complications. SARS-CoV-2 also results in the hypercoagulability issues like gangrene, stroke, pulmonary embolism, and other associated complications. This review aims to provide the latest information on the impact of the COVID-19 on pre-existing comorbidities such as CVDs, NDs, COPD, and other complications. This review will help us to understand the current scenario of COVID-19 and comorbidities; thus, it will play an important role in the management and decision-making efforts to tackle such complications.

Effective Access to Care in a Crisis Period: Hypertension Control During the COVID-19 Pandemic by Telemedicine.

OBJECTIVE: To assess the effectiveness of telemedicine video visits in the management of hypertensive patients at home during the first year of the COVID-19 pandemic. METHODS: A quantitative analysis was performed of all home video visits coded with a diagnosis of essential hypertension during the first 12 months of the COVID-19 pandemic (March 2020 through February 2021). A total of 10,634 patients with 16,194 hypertension visits were present in our national telemedicine practice database during this time. Among this population, a total of 569 patients who had 1785 hypertension visits met the criteria of having 2 or more blood pressure (BP) readings, with the last BP reading occurring in the report period. We analyzed baseline characteristics and BP trends of these 569 patients during the study period. Voluntarily submitted patient satisfaction ratings, which were systematically requested at the end of each visit, were also analyzed. RESULTS: The mean age of the patients in this study cohort of 569 patients was 43.9 years, and 48.3% (275) were women. More than 62% (355) of the patients had an initial systolic BP (SBP) above 140 mm Hg, and 25.3% (144) had an initial SBP of greater than 160 mm Hg. The average number of visits during the study period was 3.1 visits per patient; an average of 6.4 BP measurements per patient were available. During the study period, 77% (438) of the patients experienced an improvement in either SBP or diastolic BP (DBP), with mean reductions of -9.7 mm Hg and -6.8 mm Hg in SBP and DBP, respectively. A total of 416 patients in the cohort started with a BP above 140/90 mm Hg. For this subset of patients, 55.7% (232) achieved a BP of 140/90 mm Hg or lower by the end of the study period, and the average reductions in SBP and DBP were -17.9 mm Hg and -12.8 mm Hg, respectively, which corresponded to improvements of 11.2% and 12.4%. These improvements did not vary significantly when patients were stratified by age, sex, or geographic region of residence (rural vs urban/suburban). Voluntarily submitted patient surveys indicated a high degree of patient satisfaction, with a mean satisfaction score of 4.94 (5-point scale). CONCLUSION: Clinician-patient relationships established in a video-first telemedicine model were broadly effective for addressing suboptimally controlled hypertension. Patient satisfaction with these visits was high.

Brainstem stroke: A fatal thromboembolic event after new onset atrial fibrillation during covid-19 infection: A case report and literature review.

Coronavirus disease (COVID-19) disease is a serious pandemic that put the world on an exceptional sanitary alert. It is a multifaceted disease, since it can affect the lung, the cardiovascular system and the central nervous system at the same time. A 66-year-old man, diabetic, hypertensive, admitted to the emergency room for medical management of acute dyspnea, diagnosed with COVID-19 infection. The evolution is marked by respiratory distress as well as new onset atrial fibrillation and a severe ischemic stroke of the brainstem. COVID-19 disease is associated with very serious thromboembolic complications of high incidence, and this is explained by the coagulopathy secondary to the alteration of the microcirculation after the hyper-inflammatory state. Ischemic stroke is one of these complications. The occurrence of new onset atrial fibrillation during COVID-19 infection makes the incidence of ischemic stroke very high and the prognosis more severe. The treatment is mainly based on antithrombotic therapy. Thromboembolic complications remain a real problem to manage in COVID-19 patients given the several mechanisms that promote this situation.

Long-Haul Post-COVID-19 Symptoms Presenting as a Variant of Postural Orthostatic Tachycardia Syndrome: The Swedish Experience.

Changing to remote management of a community heart failure population during COVID-19 - Clinician and patient perspectives'.

BACKGROUND: The COVID pandemic has challenged the traditional methods used in care of patients with heart failure (HF). Remote management of HF patients has been recommended in order to maintain routine standards of care, but satisfaction with this platform of care is unknown. We set out to address the physician and patient opinion of remote management of HF during COVID-19. METHODS AND RESULTS: An observational report of the use of a Structured Telephonic assessment (STA) in stable outpatient HF patients. Physician grading of the STA was complemented by 100 randomly chosen patients to ascertain patient satisfaction and comment. 278 patients underwent a STA. Patient preference for STA was noted in 66%. Convenience was the single most cited reason for this preference (83.3%). The STA was deemed satisfactory by clinicians in 67.6%. The two-leading reasons for clinician dissatisfaction were data gaps providing a barrier to titration (55.6%) and need for clinical exam (18.9%). The annual review appointment visit subtype possessed the highest levels of satisfaction congruence amongst both clinicians and patients. CONCLUSION: In summary, this report demonstrates reasonable patient / physician satisfaction with STA, and provides some direction on how this care platform might be sustained beyond the COVID crisis.

Fetal deaths in pregnancies with SARS-CoV-2 infection in Brazil: A case series.

BACKGROUND: There are few reports of miscarriages or stillbirths in women infected with SARS-CoV-2. We present five consecutive cases of fetal death (≥12 weeks) without other putative causes in women with laboratory-confirmed (RT-PCR) COVID-19 managed in a single Brazilian institution. CASE SERIES: All five women were outpatients with mild or moderate forms of COVID-19 and were not taking any medication. Four were nulliparous, all were overweight or obese, and none had any comorbidities or pregnancy complications that could contribute to fetal demise. Fetal death occurred at 21-38 weeks of gestation, on COVID-days 1-22. SARS-Cov-2 was detected by RT-PCR in amniotic fluid in one case and in placental specimens in two cases. All five women had acute chorioamnionitis on placental histology, massive deposition of fibrin, mixed intervillitis/villitis, and intense neutrophil and lymphocyte infiltration. One fetus had neutrophils inside alveolar spaces, suggestive of fetal infection. CONCLUSIONS: These five cases of fetal demise in women with confirmed COVID-19 without any other significant clinical or obstetric disorders suggest that fetal death can be an outcome of SARS-CoV-2 infection in pregnancy. The intense placental inflammatory reaction in all five cases raises the possibility of a direct effect of SARS-CoV-2 on the placenta.

Possible formation of pulmonary microthrombi in the early puerperium of pregnant women critically ill with COVID-19: Two case reports.

BACKGROUND: Limited data are available on the management of pregnant women with severe or critical forms of COVID-19, such as the optimal timing of provider-initiated delivery, and post-partum care, including antithrombotic prophylaxis. We present the clinical course, pre- and post-partum management, and outcomes of two pregnant women critically ill with COVID-19. CASES: Both women had confirmed SARS-CoV-2 pneumonia with rapid clinical decompensation that required admission to the intensive care unit, intubation, and delivery by emergency cesarean section at 32 and 29 weeks. Both patients clinically improved in the first two postoperative days, but this was followed by clinical, laboratory and radiological deterioration on the third postoperative day; however, they both improved again after full anticoagulation. This pattern suggests the possible formation of pulmonary microthrombi in the early puerperium. We discuss the challenges faced by the multiprofessional team in the management of these patients. CONCLUSIONS: There are few resources to guide health professionals caring for pregnant women with critical COVID-19. These two cases contribute to the rapidly evolving knowledge on the management and outcomes of pregnant women with COVID-19.
