Assessment of clinical and histopathological characteristics in COVID-19-associated mucormycosis (CAM) patients correlating with outcome: A hospital-based cross-sectional study.

Background: The second wave of the COVID-19 pandemic led to a very dreaded complication of mucormycosis. Immunosuppressive action of the COVID-19 virus, co-morbidities, for example, diabetes mellitus (DM), hypertension, use of steroids, and humidified oxygen, are among the important factors that make the patients susceptible to developing mucormycosis. Objective: The present study was conducted to identify and understand all the significant histological changes including the type and extent of tissue involvement, the pattern of inflammation, the volume of fungal hyphae, hemorrhage, etc., in patients with COVID-19 associated mucormycosis (CAM) and correlate with clinical outcome. Method: It was a retrospective cross-sectional observational study involving all the patients of CAM, who underwent debridement or biopsy over a period of 5 months, from April 01, 2021, to August 31, 2021. CAM was classified based on the radiological evaluation, clinical features, and organs involved. Different demographic, clinical, laboratory, and histologic parameters were recorded. The variables were assessed for their association with poor clinical outcomes using multiple logistic regression. P < 0.05 was considered statistically significant. Results: A total of 146 patients were included in the study with a mean age of 49.4 years and 71.2% were male. Sino-naso-palatal was the most common type of CAM (32.9%), while sino-naso-cerebral was the least common (14.3%). DM was present in 54.1% of patients, out of which 26.6% were recently diagnosed. The death occurred in 21.9% of patients. Maximum mortality was observed in CAM of sino-naso-cerebral involvement (42.9%). Total leucocyte count (TLC) [OR = 0.87; 95%CI: 0.76-0.97; P = 0.02] and C-reactive protein (CRP) [OR = 0.97; 95%CI: 0.96-0.99; P = 0.008] were significantly associated with poor outcomes. Other factors, that is, high prothrombin time, DM, ferritin, and the involvement of muscle, skin, and cartilage, were also associated with poor clinical outcomes but were not statistically significant. Similarly, high fungal volume and the presence of thrombosis were also associated with poor outcomes but were not statistically significant. Conclusion: CAM more commonly affects males with co-morbidities. TLC and CRP were significantly associated with poor outcomes. Histologically, the involvement of skin, muscle, and cartilage and the presence of excessive fungal hyphae and thrombosis were also associated with poor outcomes.

Risk factors and multi-pathogen infections in kidney transplant recipients with omicron variant pneumonia: a retrospective analysis.

BACKGROUND: Kidney transplant recipients (KTRs) are at an elevated risk of progressing to severe infections upon contracting COVID-19. We conducted a study on risk factors and multi-pathogen infections in KTRs with SARS-CoV-2 Omicron variant. METHODS: KTRs were subjected to a thorough etiological evaluation. Whenever feasible, they were also provided with bronchoscopy and bronchoalveolar lavage to enable metagenomic next-generation sequencing (mNGS), ideally within a 48-hour window post-admission. We performed a retrospective analysis for pathogens and risk factors of KTRs with the COVID-19 virus variant Omicron. RESULTS: We included thirty patients in our study, with sixteen exhibiting single infection of COVID-19 and fourteen experiencing co-infections, predominantly with Pneumocystis jirovecii. Notably, patients with severe cases demonstrated significantly elevated levels of C-reactive protein (CRP) and interleukin-6 compared to those with moderate cases (P < 0.05). Furthermore, individuals whose conditions progressed had markedly higher baseline serum creatinine levels than those without such progression (P < 0.05). The presence of heart failure, acute exacerbation of renal dysfunction, and a history of opportunistic infections were significantly associated with a higher likelihood of deterioration and hospital admission due to the SARS-CoV-2 Omicron variant, as compared to the control group (P < 0.05). In subsequent follow-up analysis, the all-cause rehospitalization rate was observed to be 21.4%, with Pneumocystis jirovecii infection accounting for half of these cases. CONCLUSION: Among KTRs, a significant coinfection rate of 47% was observed, with Pneumocystis jirovecii emerging as the predominant pathogen in these cases. The development of heart failure, acute exacerbation of chronic renal dysfunction, and a prior history of opportunistic infections have been identified as potential risk factors that may contribute to clinical deterioration in KTRs. Additionally, Pneumocystis jirovecii infection has been established as a critical factor influencing the rate of all-cause rehospitalization within this patient population.

Significantly Elevated CA 19-9 after COVID-19 Vaccination and Literature Review of Non-Cancerous Cases with CA 19-9 > 1000 U/mL.

BACKGROUND: CA 19-9 is a commonly assessed tumor marker, considered characteristic of pancreatic ductal adenocarcinoma (PDAC) and biliary tract cancers; however, the positive predictive value of CA 19.9 is too low, and the usage of CA 19.9 as a screening tool in the healthy population remains controversial. METHODS: The presented case illustrates a reversed diagnosis of highly elevated serum CA 19-9 levels in a 54-year-old female complaining of pain in the epigastric region, shortly after COVID-19 vaccination. Laboratory tests showed a significantly elevated level of the CA 19-9 marker (>12,000 U/mL, reference value: <37 U/mL) with normal pancreatic enzyme activity. The patient underwent imaging examination, which showed no abnormalities, except for increased pancreatic dimension and areas of fluid signal in the pancreas in magnetic resonance imaging (MRI), which may correspond to autoimmune pancreatitis (AIP). The patient remains asymptomatic with a recommendation for a follow-up MRI in 12 months. RESULTS: A literature review conducted revealed multi-causal CA 19-9 increases above 1000 U/mL, including non-cancerous diseases of the lung, pancreas, liver, ovary, kidney, and others. The median concentration of CA 19-9 regardless of the cause of disease was 2810 U/mL (IQR ± 6895). The median CA 19-9 values in men and women were 3500 (IQR ± 10,050) and 2455 (IQR ± 3927), respectively, and differ significantly between the compared groups (p < 0.05). There was no difference between CA 19-9 values and the categorized cause of the increase. CONCLUSIONS: Conducting differential diagnosis, it should not be forgotten that most international guidelines recommend the use of CA 19-9 only in conjunction with pathology of pancreas in radiological imaging; however, even such a combination can point the diagnostic pathway in the wrong direction. A highly elevated CA 19-9 level, typically associated with PDAC, may be the result of benign disease including AIP related to COVID-19 vaccination.

Clinical and immunological features of COVID-19 in patients with anti-MDA5 dermatomyositis during the omicron wave in Chongqing, China.

Patients with anti-melanoma differentiation-associated gene 5 (anti-MDA5) dermatomyositis (DM) have a higher risk of coronavirus disease 2019 (COVID-19) infection. In this longitudinal observational study, we aimed to investigate the clinical and immunological features of these patients after COVID-19 infection. A total of 73 patients with anti-MDA5 DM were recruited from the Second Affiliated Hospital of Chongqing Medical University during the Omicron wave epidemic. Clinical data were collected by questionnaire survey and electronic medical records. Blood samples were used to determine the immunity responses. From December 9, 2022 to March 31, 2023, 67 patients were eligible for final analysis; 68.7% of them were infected with COVID-19. The most common symptoms observed in COVID-19 were upper respiratory symptoms, most cases were mild or moderate (97.8%). The clinical laboratory indexes were relativity stable in patients after infection (all p > 0.05). Vaccination is not a protective factor against the Omicron infection (odds ratio: 2.69, 95% confidence interval: 0.81-8.93, p = 0.105). Both wildtype (WT) neutralizing antibodies titer and BA.5-specific immunoglobulin G titer were significantly enhanced after infection (all p < 0.01), which was as high as healthy controls (HCs). The memory B-cell responses were similar between the patients with anti-MDA5 DM and HCs (p > 0.05). However, both the WT-specific CD8+ T cells and CD4+ T cells were reduced in patients with anti-MDA5 DM (all p < 0.05). In conclusion, patients with anti-MDA5 DM did not deteriorate the COVID-19, in turn, COVID-19 infection did not increase the risk of anti-MDA5 DM exacerbation. The humoral responses were robust but the cellular responses were weakened after COVID-19 infection.

Photocatalysis air purification systems for coronavirus removal: Current technologies and future trends.

Air pollution causes extreme toxicological repercussions for human health and ecology. The management of airborne bacteria and viruses has become an essential goal of air quality control. Existing pathogens in the air, including bacteria, archaea, viruses, and fungi, can have severe effects on human health. The photocatalysis process is one of the favorable approaches for eliminating them. The oxidative nature of semiconductor-based photocatalysts can be used to fight viral activation as a green, sustainable, and promising approach with significant promise for environmental clean-up. The photocatalysts show wonderful performance under moderate conditions while generating negligible by-products. Airborne viruses can be inactivated by various photocatalytic processes, such as chemical oxidation, toxicity due to the metal ions released from photocatalysts composed of metals, and morphological damage to viruses. This review paper provides a thorough and evaluative analysis of current information on using photocatalytic oxidation to deactivate viruses.

COVID-19 virus and clinical outcome on the newborns at the Neonatal Department of Intensive Medicine in Bratislava, Slovakia.

AIM: The aim of this study was to analyse the group of newborns who were admitted at Neonatal Department of Intensive Medicine in Bratislava Faculty of Medicine Comenius University in Bratislava and National Institute of Children´s Diseases in the period from 08.01.2021 until 07.07.2023 who were affected by the COVID-19 virus from mother before birth, from staff or in family or were only in contact with COVID-19 positive person. RESULTS: Most common symptoms in newborns within our findings included fever, upper respiratory symptoms, and diarrhoea. Detailed analysis of prenatal and postnatal characteristics, clinical findings are presented in tables 1-3. CONCLUSION: COVID-19 pandemic had a great impact on the pregnant women as well as on prenatal and postnatal development of the child. Our results reveal that the severity of symptoms in COVID-19 infected newborns from our sample was low. It is important to implement adequate neonatal practices for early detection of illnesses, especially in relation to COVID-19 which will subsequently allow early intervention and reduce neonatal mortality. Future challenges for all countries include the implementation of higher hygiene standards, prevention of spreading, more sensitive tests to use in the first day of life (Tab. 3, Ref. 36).

Evaluation of falls in older persons in the emergency department during the early Coronavirus-2019 pandemic and pre-pandemic periods.

PURPOSE: This study aimed to investigate the clinical characteristics, outcomes and healthcare costs of older patients presented to the emergency department (ED) with falls in the periods before and during the Coronavirus disease-2019 (COVID-19) pandemic. METHODS: Hospital records one year before and after the onset of the COVID-19 pandemic were retrospectively analyzed through "International Statistical Classification of Diseases-10th Revision" codes. Age, gender, falls, triage classification, length of stay (LOS) in the hospital and the ED, COVID-19 status, Glasgow Coma scale, consultations-comorbidities, injury status, outcomes in the ED, and costs were recorded. RESULTS: The study comprised of 3187 patients aged ≥ 65 years admitted to the ED of a university hospital between March 2019 and 2021. In terms of pre-pandemic and pandemic periods; older patients presenting with falls to the ED, consultations, Charlson Comorbidity Index, and LOS in the ED were lower in the pandemic period, but costs were higher (p = 0.03, p = 0.01, p = 0.01, p = 0.01 and p = 0.02, respectively). Hospitalization/mortality rates were higher in COVID-19 positive patients (77.2%) than in COVID-19 negative patients (4.6%) within the pandemic period and the patients in the pre-pandemic period (22.8%), and the costs, as well (both p = 0.01). CONCLUSION: Though the number of fall-related presentations of older persons to the ED, comorbidity burden, consultations, and the LOS in the ED was lower, direct costs were higher during the pandemic period, particularly for COVID-19 positive older patients admitted to ED with falls than the pre-pandemic period, and those patients were with poorer outcomes.

[The nature of the actual nutrition of elderly residents of the European North of Russia who had community-acquired pneumonia, not associated with the COVID-19 virus, from the standpoint of the possibility of the microelement state disorder.]

An increasing number of elderly and senile people characterises the structure of modern society. With ageing, a violation of the microelement homeostasis of the human body occurs. The natural biogeochemical conditions of the North initiate a metabolic restructuring of the body, accompanied by changes in the microelement state, which disrupts the functions of protective systems and increases the risk of developing diseases. The purpose of the study is to investigate the possibility of developing a mineral metabolism disorder in elderly and senile people who have suffered community-acquired pneumonia, not associated with the COVID-19 virus, due to the nutritional habits in the Republic of Karelia. The assessment of food rations and the study of the awareness of healthy nutrition of these individuals were carried out, according to a specially designed questionnaire. Of the 100 questionnaires distributed, 89 suitable for analysis were studied, taking into account the gender of the respondents. As a result of the study, it was demonstrated that the nutrition of elderly and senile people cannot meet the body's needs for trace elements due to insufficient consumption of vegetables and fruits, dairy and meat products, and fish.

Mathematical model of aging in COVID-19.

Background: The aim was examination of the intimamedia thickness of carotid arteries in COVID-19 infection. Methods: In 50 patients, the thickness of the intimomedial complex (IMT) in the common carotid arteries was measured. The values were compared with the control group in 2006-9. The condition of the lungs was assessed by ultrasound score (It score) (0-42) as mild (0-14) or mediumsevere (15-28) Covid. IMT thickening risk factors and the value of fibrinogen, IL-6 and CRP were recorded. Two IMT prediction models were formed. The socio-epidemiological model predicts the development of IMT based on epidemiological factors. Apart from these factors, the second model also includes the values of the mentioned biomarkers. Results: It score 20±6, IMT values right: median 0.99 mm, p25=0.89, p75=1.14; left: 1±0.22 mm. Control: IMTright: median 0.7 mm, p25=0.68 mm; p75=0-9 mm; left: median=0.75 mm, p25=0.6 mm, p75=1.0 mm. The group/control difference is highly significant. Epide mio - logical model: logit (IMT)= 4.463+(2.021+value for GEN)+(0.055x AGE value)+(-3.419x RF value)+(-4.447x SM value)+(5.115x HTA value)+(3.56x DM value)+ (22.389x LIP value)+(24.206x CVD value)+(1.449x other value)+(-0.138x It score value)+(0.19xBMI value). Epidemiological-inflammatory model: logit (IMT)=5.204+ (2.545x GEN value)+(0.076x AGE value)+(-6.132x RF value)+(-7.583x SM value)+(8.744x HTA value)+(6.838x DM value)+(25.446x LIP value)+(28.825x CVD value)+ (2.487x other value)+(-0.218xIt score value)+(0.649x BMI value) +(-0.194x fibrinogen value)+(0.894x IL-6 value)+(0.659x CRP value). Values for both models Exp(B)=4.882; P of sample=0.83; logit=-0.19; OR= 23.84; model accuracy for the first model 87% and for the second 88%; Omnibus test of the first model c2=34.324; p=0.000; reliability coefficient -2LogLH=56.854; Omnibus test of the second model c2=39.774; p=0.000; and -2LogLH=51.403. Conclusions: The ageing of blood vessels in COVID-19 can be predicted.

The Development and Integration of a Safety Officer Role to Facilitate Prevention of COVID-19 Virus Transmission in an Adult Inpatient Rehabilitation Setting Using Collaborative Change Leadership Methodology.

BACKGROUND: With the onset of the COVID-19 pandemic, a large urban academic hospital responded by creating the temporary role of a "Safety Officer (SO)." The key task of the SO role was to supervise staff donning and doffing personal protective equipment (PPE) and provide real-time feedback on their performance. The support for safe donning and doffing would contribute to staff well-being by reducing their fear of infection transmission. METHODS: A Collaborative Change Leadership (CCL) approach was used to facilitate the development, implementation, and evaluation of the role. This included an iterative feedback process with clinicians and safety officers to continually refine the role. FINDINGS: Feedback indicated value in the initiative as increasing staff confidence about preventing virus transmission, as well as their sense of safety at work. Areas for future improvement included additional communication strategies for interprofessional teams and external partners, as well as planning around logistics to better support the safety officers in performing this new, temporary role. CONCLUSIONS/APPLICATION TO PRACTICE: The Safety Officer role was able to help alleviate concerns regarding potential infection transmission and contribute positively to staff well-being.

Optical Biosensors for the Diagnosis of COVID-19 and Other Viruses-A Review.

The sudden outbreak of the COVID-19 pandemic led to a huge concern globally because of the astounding increase in mortality rates worldwide. The medical imaging computed tomography technique, whole-genome sequencing, and electron microscopy are the methods generally used for the screening and identification of the SARS-CoV-2 virus. The main aim of this review is to emphasize the capabilities of various optical techniques to facilitate not only the timely and effective diagnosis of the virus but also to apply its potential toward therapy in the field of virology. This review paper categorizes the potential optical biosensors into the three main categories, spectroscopic-, nanomaterial-, and interferometry-based approaches, used for detecting various types of viruses, including SARS-CoV-2. Various classifications of spectroscopic techniques such as Raman spectroscopy, near-infrared spectroscopy, and fluorescence spectroscopy are discussed in the first part. The second aspect highlights advances related to nanomaterial-based optical biosensors, while the third part describes various optical interferometric biosensors used for the detection of viruses. The tremendous progress made by lab-on-a-chip technology in conjunction with smartphones for improving the point-of-care and portability features of the optical biosensors is also discussed. Finally, the review discusses the emergence of artificial intelligence and its applications in the field of bio-photonics and medical imaging for the diagnosis of COVID-19. The review concludes by providing insights into the future perspectives of optical techniques in the effective diagnosis of viruses.

COVID-19 Virus and Vaccination Attitudes among Healthcare Workers in Michigan: A Cross-Sectional Study.

BACKGROUND: Defining the characteristics of healthcare worker (HCW) attitudes toward the coronavirus disease 2019 (COVID-19) vaccine can provide insights into vaccine hesitancy. This study's goal is to determine HCWs' attitudes regarding the COVID-19 vaccination and reasons for vaccine hesitancy. METHODS: This cross-sectional study surveyed HCWs working in institutions in Saginaw, Sanilac, and Wayne counties in Michigan (N = 120) using tipping-scale questions. Analysis of variance and t-test were used to measure HCWs' attitudes toward the COVID-19 virus and vaccines. RESULTS: Most HCWs received (95.9%) and recommended (98.3%) a COVID-19 vaccine. The top three factors that HCWs cited for recommending a COVID-19 vaccine were: (1) efficacy of the vaccine, (2) current exposure to patients with active COVID-19 infection and risk of virus spread, and (3) safety of vaccine and long-term follow-up. Female HCWs or HCWs aged 25-54 years were more concerned about contracting COVID-19. Physicians or HCWs aged 55-64 were less concerned regarding the effectiveness and side effects of the vaccine. CONCLUSIONS: Gender, age, ethnicity, provider type, and medical specialty showed statistically significant differences among COVID-19 attitudes. Focusing educational efforts on HCW demographics who are more likely to have negative attitudes can potentially decrease vaccine hesitancy.

Immunogenicity of the ChAdOx1 nCoV-19 vaccine in patients with hematologic malignancies.

Purpose: The present study aimed to study the immunogenicity of the ChAdOx1 nCoV-19 vaccine in patients with hematologic malignancies. Materials and Methods: This prospective cohort study of hematology patients aimed to evaluate their antibody levels against the receptor-binding domain of the severe acute respiratory syndrome coronavirus 2 spike protein and seroconversion rates following two doses of the ChAdOx1 nCoV-19 vaccine. Between June and July 2021, we enrolled 61 patients and included 44 patients in our analysis. Antibody levels were assessed 8 and 4 weeks after the first and second injections, respectively, and compared with those of a healthy group. Results: Eight weeks after the first dose, the geometric mean antibody level was 1.02 binding antibody units (BAU)/mL in the patient group and 37.91 BAU/mL in the healthy volunteer group (p<0.01). Four weeks after the second dose, the geometric mean antibody level was 9.44 BAU/mL in patients and 641.6 BAU/mL in healthy volunteers (p<0.01). The seroconversion rates 8 weeks after the first dose were 27.27% and 98.86% in the patient and healthy volunteer groups, respectively (p<0.001). The seroconversion rate 4 weeks after the second dose was 47.73% in patients and 100% in healthy volunteers. Factors leading to lower seroconversion rates were rituximab therapy (p=0.002), steroid therapy (p<0.001), and ongoing chemotherapy (p=0.048). Factors that decreased antibody levels were hematologic cancer (p<0.001), ongoing chemotherapy (p=0.004), rituximab (p<0.001), steroid use (p<0.001), and absolute lymphocyte count <1,000/mm3 (p=0.009). Conclusion: Immune responses were impaired in individuals with hematologic malignancies, particularly patients undergoing ongoing therapy and B-cell-depleting therapy. Additional vaccinations should be considered for these patients, and further investigated.

Population Older than 69 Had Similar Fatality Rates Independently If They Were Admitted in Nursing Homes or Lived in the Community: A Retrospective Observational Study during COVID-19 First Wave.

The aim of this study is to assess the influence of living in nursing homes on COVID-19-related mortality, and to calculate the real specific mortality rate caused by COVID-19 among people older than 20 years of age in the Balaguer Primary Care Centre Health Area during the first wave of the pandemic. We conducted an observational study based on a database generated between March and May 2020, analysing COVID-19-related mortality as a dependent variable, and including different independent variables, such as living in a nursing home or in the community (outside nursing homes), age, sex, symptoms, pre-existing conditions, and hospital admission. To evaluate the associations between the independent variables and mortality, we calculated the absolute and relative frequencies, and performed a chi-square test. To avoid the impact of the age variable on mortality and to assess the influence of the "living in a nursing home" variable, we established comparisons between infected population groups over 69 years of age (in nursing homes and outside nursing homes). Living in a nursing home was associated with a higher incidence of COVID-19 infection, but not with higher mortality in patients over 69 years of age (p = 0.614). The real specific mortality rate caused by COVID-19 was 2.270/00. In the study of the entire sample, all the comorbidities studied were associated with higher mortality; however, the comorbidities were not associated with higher mortality in the infected nursing home patients group, nor in the infected community patients over 69 years of age group (except for neoplasm history in this last group). Finally, hospital admission was not associated with lower mortality in nursing home patients, nor in community patients over 69 years of age.

The impact of educational interventions on COVID-19 and vaccination attitudes among patients in Michigan: A prospective study.

Background: Mass vaccination serves as an effective strategy to combat the COVID-19 pandemic. Vaccine hesitancy is a recognized impediment to achieving a vaccination rate necessary to protect communities. However, solutions and interventions to address this issue are limited by a lack of prior research. Methods: Over 200 patients from 18 Michigan counties participated in this study. Each participant received an initial survey, including demographical questions and knowledge and opinion questions regarding COVID-19 and vaccines. Participants were randomly assigned an educational intervention in either video or infographic format. Patients received a post-survey to assess changes in knowledge and attitudes. Paired sample t-tests and ANOVA were used to measure the effectiveness of the educational interventions. Participants also elected to complete a 3-month follow-up survey. Results: Patients showed increased knowledge after the educational intervention in six out of seven COVID-19 topics (p < 0.005). There was increased vaccine acceptance after the intervention but no difference in the effectiveness between the two intervention modalities. Post-intervention, more patients believed in CDC recommendations (p = 0.005), trusted the vaccine (p = 0.001), believed the vaccines had adequate testing (p = 0.019), recognized prior mistreatment in the medical care system (p = 0.005), agreed that a source they trust told them to receive a vaccine (p = 0.015), and were worried about taking time off of work to get a vaccine (p = 0.023). Additionally, post-intervention, patients were less concerned about mild reactions of the virus (p = 0.005), the rapid development of the vaccines (p < 0.001), and vaccine side effects (p = 0.031). Data demonstrated that attitude and knowledge improved when comparing pre-educational intervention to follow-up but decreased from post-intervention to follow-up. Conclusion: The findings illustrate that educational interventions improved COVID-19 and vaccine knowledge among patients and that the knowledge was retained. Educational interventions serve as powerful tools to increase knowledge within communities and address negative views on vaccination. Interventions should be continually utilized to reinforce information within communities to improve vaccination rates.

Influence of the COVID-19 pandemic on labor and childbirth care practices in Brazil: a cross-sectional study.

BACKGROUND: It has been hypothesized that the coronavirus disease 2019 (COVID-19) pandemic may have changed the conduct of obstetric practices at the time of labor, delivery, and birth. In Brazil, many practices lacking scientific evidence are implemented in this care, which is charcaterized by excessive use of unnecessary interventions. This scenario may have been worsened by the pandemic. Thus, we analyzed the effects of the pandemic on care during prenatal care and delivery by comparing the results of two surveys (one was administered before the pandemic and the other during the pandemic) in public hospitals in Belo Horizonte - Minas Gerais (MG), Brazil. METHODS: This cross-sectional and comparative study analyzed preliminary data from the study "Childbirth and breastfeeding in children of mothers infected with SARS-CoV-2", which was conducted in three referral maternity hospitals in Belo Horizonte - MG during the pandemic in the first half of 2020 in Brazil. The final sample consisted of 1532 eligible women. These results were compared with data from 390 puerperae who gave birth in the three public hospitals in the study "Birth in Belo Horizonte: labor and birth survey", conducted before the pandemic to investigate the changes in practices of labor and delivery care for the mother and her newborn, with or without COVID-19 infection, before and during the pandemic. In this research, "Birth in Belo Horizonte: labor and birth survey", data collection was performed between November 2011 and March 2013 by previously trained nurses. Between study comparisons were performed using Pearson's chi-square test, with a confidence level of 95%, and using Stata statistical program. RESULTS: We found a significant increase in practices recommended by the World Health Organization during the pandemic including the following: diet offering (48.90 to 98.65%), non-pharmacological pain relief (43.84 to 67.57%), and breastfeeding in the newborn´s first hour of life (60.31 to 77.98%) (p < 0.001). We found a significant reduction of non-recommended interventions, such as routine use of episiotomy (15.73 to 2.09%), the Kristeller maneuver (16.55 to 0.94%), oxytocin infusion misused (45.55 to 28.07%), amniotomy (30.81 to 15.08%), and lithotomy position during labor (71.23 to 6.54%) (p < 0.001). CONCLUSION: Our study revealed a statistically significant increase in the proportion of use of recommended practices and a reduction in non-recommended practices during labor and delivery. However, despite advances in the establishment of World Health Organization recommended practices in labor, delivery, and birth, the predominance of interventionist and medicalized practices persists, which is worsened by events, such as the pandemic.

Study of the effects of in-person attendance at academic conferences on the health of the attendees under COVID-19 pandemic.

OBJECTIVE: To analyze the effects of in-person attendance at an academic conference held during the Covid-19 pandemic on the health of the attendees, as assessed based on symptoms such as fever and cough attributed to infection with the Covid-19 virus. METHODS: A questionnaire was used to survey the members of the Japan Society of Obstetrics and Gynecology (JSOG) about their health during the period from August 7 to August 12, 2022, after the 74th Annual Congress of the JSOG, which was held August 5 to 7. RESULTS: Our survey yielded responses from 3054 members (1566 of whom had attended the congress in person and 1488 of whom had not attended in person); 102 (6.5%) of the in-person attendees and 93 (6.2%) of the people who did not attend in person reported problems with their health. No statistically significant difference was found between these two groups (p = 0.766). In a univariate analysis of factors affecting the presence of health problems, attendees with age ≥60 years had significantly fewer health problems than attendees who were in their 20s (odds ratio: 0.366 [0.167-0.802; p = 0.0120]). In a multivariate analysis, attendees who had received four vaccine shots had significantly fewer health problems than attendees who had received three shots (odds ratio: 0.397 [0.229-0.690, p = 0.0010]). CONCLUSION: Congress attendees who took precautions at the congress to avoid being infected and who had a high vaccination rate did not develop significantly more health problems associated with in-person attendance at the congress.

Antimicrobial use in patients with confirmed COVID-19 infection: a cross-sectional study

@#Objective: The ongoing coronavirus disease (COVID-19) pandemic is exacerbating optimal antibiotic stewardship and the promotion of bacterial resistance due to the over-prescribing of antibiotics for patients with COVID-19. This study aimed to determine the prevalence of antibiotic therapy in patients with COVID-19 infection and explore the association of antibiotic prescribing with patients’ demographics and clinical characteristics. Methods: A retrospective analytical cross-sectional study was conducted at a tertiary hospital and training institution in Baguio City, the Philippines from March 2020 to March 2021. Univariate and multivariable logistic regression was used to compare COVID-19 patients who were prescribed antibiotics with those who were not. Results: Of the 157 patients hospitalized with COVID-19 infection, 90 (57.3%) received antibiotics, with only three (1.9%) having confirmed bacterial coinfection. Among those prescribed antibiotics, azithromycin was the most frequently prescribed antibiotic (43.3%), followed by ceftriaxone (33.1%), piperacillin-tazobactam (15.3%), ceftazidime (5.1%), moxifloxacin (1.3%), amikacin (0.6%), ampicillin and sulbactam (0.6%), cefuroxime (0.6%), metronidazole (0.6%) and penicillin (0.6%). Antibiotic use was associated with factors such as having bilateral infiltrates on chest X-ray, the severity of COVID-19 infection and high white blood cell counts. Discussion: Antibiotic use was high among patients with confirmed COVID-19 despite a low prevalence of confirmed bacterial coinfection. This may be due to the similarities in the clinical manifestations of both viral and bacterial infections.
