Clinical Description

This study aimed to summarize the epidemiological and clinical characteristics of COVID-19 from Western Mexico people during 2020. A retrospective analysis from an electronic database of people visiting a sentinel center for molecular SARS-CoV-2 confirmatory diagnosis by RT-PCR from April to December 2020 was carried out for epidemiological and clinical description of COVID-19. Out of 23,211 patients evaluated, 6918 (29.8%) were confirmed for SARS-CoV-2 infection (mean age 38.5 ± 13.99), mostly females (53.8%). Comorbidities, such as diabetes (34.7%), obesity (31.15%), and hypertension (31.8%), presented an increased odds OR = 1.27, CI = 1.14–1.41; OR = 1.08, CI = 1.01–1.16; and OR = 1.09, CI = 0.99–1.19, respectively, for viral-infection. Moreover, fever, headache, and dry cough were the most frequent symptoms. No infection difference among sex was found. Those patients >60 years old were prone to COVID-19 severity (OR = 3.59, CI = 2.10–6.14), evaluated by the number of manifested symptoms, increasing with age. In conclusion, a high SARS-CoV-2 prevalence was found in Western Mexico. Comorbidities were frequent in infected people; nevertheless, no association with disease outcomes was observed, in contrast with the highest disease severity risk found in older patients; however, continuous monitoring should be carried since comorbidities have been reported as aggravating factors. This study can help the health officials for the elaboration of planning efforts of the disease management and others in the future.

Abstract Background The epidemiology and outcomes of COVID-19 patients in Thailand are scarce. Methods This retrospective cohort study included adult hospitalized patients who were diagnosed with COVID-19 at Siriraj Hospital during February 2020 to April 2020. Results The prevalence of COVID-19 was 7.5% (107 COVID-19 patients) among 1409 patients who underwent RT-PCR for SARS-CoV-2 detection at our hospital during the outbreak period. Patients with COVID-19 presented with symptoms in 94.4%. Among the 104 patients who were treated with antiviral medications, 78 (75%) received 2-drug regimen (lopinavir/ritonavir or darunavir/ritonavir plus chloroquine or hydroxychloroquine), and 26 (25%) received a 3-drug regimen with favipiravir added to the 2-drug regimen. Disease progression was observed in 18 patients (16.8%). All patients with COVID-19 were discharged alive. Conclusions The prevalence of COVID-19 was 7.5% among patients who underwent RT-PCR testing, and 10% among those having risk factors for COVID-19 acquisition. Combination antiviral therapies for COVID-19 patients were well-tolerated and produced a favorable outcome.

We investigated an outbreak of acute gastroenteritis due to human astrovirus in a daycare center, describing the transmission mechanism, the most affected age groups, conditioning factors and the extent of the outbreak among household contacts of the daycare center attenders. Data were collected from persons exposed at the daycare center and their home contacts. Fecal samples from affected and non-affected daycare center attenders were analyzed for viruses causing acute gastroenteritis by RT-PCR. The percentage of households affected and the attack rates (AR) were calculated. The attack rates were compared using the rate ratio (RR) with 95% confidence intervals. Information was obtained from 245 people (76 attenders and 169 contacts) of whom 49 were clinical cases. Five HAstV-4, two HAstV-8 and three non-typable HAstV cases were identified (six from clinical cases and four from asymptomatic infected people). The global AR was 20% (41.2% in children aged < 2 years). Data were obtained from 67 households: 20 households of affected attenders and 47 of non-affected attendees. Household contacts of affected attenders had a higher AR (74.3%) than that of non-affected attendees (2.4%). We found asymptomatic infections amongst daycare attendees. The transmission of HAstV during the outbreak was not limited to the daycare center but extended to household contacts of both affected and non-affected attenders.

Objectives To investigate the clinical characteristics, survival and prognosis of patients with multiple myeloma (MM) and head extramedullary plasmacytoma (EMP). Methods Forty MM patients were enrolled in the study (18 men, 22 women; median age, 55 years). Results Median overall survival (OS) and progression-free survival (PFS) were 24 (5–78) months and 17 (2–36) months, respectively. The 2-, 3- and 5-year OS rates were 51%, 20% and 7%, respectively. The 2-year PFS was 15%. Median OS and PFS in patients administered velcade were 26 (18–50) and 22.5 (5–78) months, compared with 20 (10–30) and 13.5 (2–36) months in patients without velcade, respectively. Median OS was 23.5 (5–50) months in patients with EMP at MM diagnosis ( n = 25) and 36 (22–78) months in patients with head EMP diagnosed during the disease course ( n = 15). Sixteen MM patients had EMP invasion of the head only and 24 had invasion at multiple sites. Median OS was 25 (22–78) months in patients with EMP of the head only and 22 (5–78) months in patients with EMP invasion at multiple sites. Conclusion MM patients with head EMP show a more aggressive disease course and shorter OS and PFS. The prognosis of these patients is poor, especially in patients with head EMP at MM diagnosis, though combined chemotherapy and radiotherapy may prolong survival.

Background Most of epidemiological models applied for COVID-19 do not consider heterogeneity in infectiousness and impact of superspreaders, despite the broad viral loading distributions amongst COVID-19 positive people (1-1 000 000 per mL). Also, mass group testing is not used regardless to existing shortage of tests. I propose new strategy for early detection of superspreaders with reasonable number of RT-PCR tests, which can dramatically mitigate development COVID-19 pandemic and even turn it endemic. Methods I used stochastic social-epidemiological SEIAR model, where S-suspected, E-exposed, I-infectious, A-admitted (confirmed COVID-19 positive, who are admitted to hospital or completely isolated), R-recovered. The model was applied to real COVID-19 dynamics in London, Moscow and New York City. Findings Viral loading data measured by RT-PCR were fitted by broad log-normal distribution, which governed high importance of superspreaders. The proposed full scale model of a metropolis shows that top 10% spreaders (100+ higher viral loading than median infector) transmit 45% of new cases. Rapid isolation of superspreaders leads to 4-8 fold mitigation of pandemic depending on applied quarantine strength and amount of currently infected people. High viral loading allows efficient group matrix pool testing of population focused on detection of the superspreaders requiring remarkably small amount of tests. Interpretation The model and new testing strategy may prevent thousand or millions COVID-19 deaths requiring just about 5000 daily RT-PCR test for big 12 million city such as Moscow. Though applied to COVID-19 pandemic the results are universal and can be used for other infectious heterogenous epidemics. Funding No funding

BackgroundSex and gender are crucial variables in coronavirus disease 2019 (COVID-19). We sought to provide information on differences in clinical characteristics and outcomes between male and female patients and to explore the effect of estrogen in disease outcomes in patients with COVID-19.MethodIn this retrospective, multi-center study, we included all confirmed cases of COVID-19 admitted to four hospitals in Hubei province, China from Dec 31, 2019 to Mar 31, 2020. Cases were confirmed by real-time RT-PCR and were analyzed for demographic, clinical, laboratory and radiographic parameters. Random-effect logistic regression analysis was used to assess the association between sex and disease outcomes.ResultsA total of 2501 hospitalized patients with COVID-19 were included in the present study. The clinical manifestations of male and female patients with COVID-19 were similar, while male patients have more comorbidities than female patients. In terms of laboratory findings, compared with female patients, male patients were more likely to have lymphopenia, thrombocytopenia, inflammatory response, hypoproteinemia, and extrapulmonary organ damage. Random-effect logistic regression analysis indicated that male patients were more likely to progress into severe type, and prone to ARDS, secondary bacterial infection, and death than females. However, there was no significant difference in disease outcomes between postmenopausal and premenopausal females after propensity score matching (PSM) by age.ConclusionsMale patients, especially those age-matched with postmenopausal females, are more likely to have poor outcomes. Sex-specific differences in clinical characteristics and outcomes do exist in patients with COVID-19, but estrogen may not be the primary cause. Further studies are needed to explore the causes of the differences in disease outcomes between the sexes.

AbstractObjectiveTo estimate the effectiveness of mRNA covid-19 vaccines against symptomatic infection and severe outcomes (hospital admission or death).DesignTest negative design study.SettingOntario, Canada between 14 December 2020 and 19 April 2021.Participants324 033 community dwelling people aged ≥16 years who had symptoms of covid-19 and were tested for SARS-CoV-2.InterventionsBNT162b2 (Pfizer-BioNTech) or mRNA-1273 (Moderna) vaccine.Main outcome measuresLaboratory confirmed SARS-CoV-2 by reverse transcription polymerase chain reaction (RT-PCR) and hospital admissions and deaths associated with SARS-CoV-2 infection. Multivariable logistic regression was adjusted for personal and clinical characteristics associated with SARS-CoV-2 and vaccine receipt to estimate vaccine effectiveness against symptomatic infection and severe outcomes.ResultsOf 324 033 people with symptoms, 53 270 (16.4%) were positive for SARS-CoV-2 and 21 272 (6.6%) received at least one dose of vaccine. Among participants who tested positive, 2479 (4.7%) were admitted to hospital or died. Vaccine effectiveness against symptomatic infection observed ≥14 days after one dose was 60% (95% confidence interval 57% to 64%), increasing from 48% (41% to 54%) at 14-20 days after one dose to 71% (63% to 78%) at 35-41 days. Vaccine effectiveness observed ≥7 days after two doses was 91% (89% to 93%). Vaccine effectiveness against hospital admission or death observed ≥14 days after one dose was 70% (60% to 77%), increasing from 62% (44% to 75%) at 14-20 days to 91% (73% to 97%) at ≥35 days, whereas vaccine effectiveness observed ≥7 days after two doses was 98% (88% to 100%). For adults aged ≥70 years, vaccine effectiveness estimates were observed to be lower for intervals shortly after one dose but were comparable to those for younger people for all intervals after 28 days. After two doses, high vaccine effectiveness was observed against variants with the E484K mutation.ConclusionsTwo doses of mRNA covid-19 vaccines were observed to be highly effective against symptomatic infection and severe outcomes. Vaccine effectiveness of one dose was observed to be lower, particularly for older adults shortly after the first dose.

Abstract Introduction The threshold for surgery has increased during the COVID-19 pandemic. A widely cited Chinese study (n = 34) reported postoperative COVID-19 pneumonia and mortality rates of 100% and 21% respectively [1]. This audit assessed outcomes after abdominal surgery across three hospitals within Mid & South Essex NHS Foundation Trust. Methods Patients undergoing abdominal surgery at Basildon University Hospital, Mid Essex Hospital and Southend University Hospital between 1st March and 27th April 2020 were included. Obstetric, gynaecological, vascular, inguinal/femoral hernia, and skin operations were excluded. Electronic data collection was supplemented by telephone follow-up. Results 306 patients were included. The median age was 57 years. 148 (48.4%) were female. 156 (51.0%) and 150 (49.0%) patients underwent elective and emergency surgery respectively. The preoperative and postoperative SARS-CoV-2 rates (based on RT-PCR or imaging) were 0.3% (n = 1) and 4.6% (n = 14) respectively. 84.6% (n = 259) did not have RT-PCR tests. All-cause 30-day mortality was 3.6% (n = 11). Amongst patients with SARS-CoV-2, mortality was 50% (7/14), occurring only after emergency surgery. Elective (vs. emergency) surgery was associated with lower postoperative SARS-CoV-2 (0.6% vs. 8.7%; p &lt; 0.001) and mortality (0.6% vs. 6.7%; p = 0.005). At follow-up, 79.1% (242/306) of patients responded, most (85.1%; 206/242) without major clinical issue. Conclusion Local SARS-CoV-2 and mortality rates are lower than previously reported [1]. Perioperative COVID-19 carries a high mortality risk. We recommend perioperative SARS-CoV-2 testing for all patients and cohorting by infection status. References 1.

: The pandemic, well-known as COVID-19, has been brought about by the coronavirus SARS-CoV-2 and it has distinct characteristics from other coronavirus-related epidemics. This pandemic has been ravaging the whole world for more than a year now and no drugs or vaccines have been found to eliminate this virus from the infected people effectively; only physical measures like social distancing, hand washing and face-mask wearing have been taken to reduce its spreading and very recently Veklury (remdesivir) has been permitted by the USFDA to manage the critical patients. This disease can be asymptomatic but when it is symptomatic, it presents with respiratory problems and cold- or flu-like symptoms which can be diagnosed with a chest CT and confirmed with RT-PCR tests. In this review, the taxonomy and structure of SARS-CoV-2 and history, transmission, epidemiology, pathology, clinical features and impacts of the COVID-19 have been discussed. A summary of possible drug targets, attempted physical and chemical measures, as well as vaccine candidates, have also been provided. How this coronavirus is different from other coronaviruses, the obstacles in managing this disease and the possibility of a second wave have also been reviewed. This review represents a wide range of information regarding COVID-19 and intends to be used as a comprehensive overview in this regard.

Poor Memory

The World Health Organization has declared that the spread of tuberculosis is a global emergency. Despite the implementation of strong tuberculosis-control initiatives by WHO, this highly infectious disease continues to affect all vulnerable populations, including the elderly population. Adverse social factors and poor living conditions also affect the elderly much more than the young. The clinical characteristics of tuberculosis in older adults can be unusual and may be confused with age-related illnesses. Various factors related to old age can also cause complications in the diagnosis, treatment, and disease outcomes for tuberculosis patients. The contributory factors may be poor memory, deafness, mental confusion, or impairment of speech. In addition, therapy for tuberculosis in elderly individuals is challenging because of the increased incidence of adverse drug reactions. Hence, understanding the impact of these substantial aspects will help to overcome the problem of tuberculosis in the elderly population.
