Bilateral acute depigmentation of the iris determined in two cases after COVID-19 infection

Bilateral acute depigmentation of the iris (BADI) is a rare disease characterized by iris atrophy. Although it can be self-limiting, it is sometimes progressive and can lead to glaucoma and severe vision loss. Two female patients were admitted to our clinic because of a change in iris color following coronavirus disease 2019 (COVID-19) infection. After the exclusion of other etiologies in the eye examination, BADI was diagnosed in both cases. Thus, it was shown that COVID-19 may also be involved in the etiology of BADI.

After action review of the COVID-19 pandemic response in North West province, South Africa

Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) caused coronavirus disease 2019 (COVID-19) pandemic with major disruptions globally. Northwest Province Department of Health (NWDoH) in South Africa set up comprehensive epidemiological emergency response plans for preventing, finding, containing and stopping the spread of COVID-19 in accordance with the National Disaster Management Act. Objectives: This After-Action Report (AAR) describes the provincial response to the pandemic from September 2020 to October 2022. Method: The AAR was conducted using the World Health Organization AAR methodology. Focus groups discussed five items: coordination, leadership and governance; epidemiology, surveillance and laboratory; case management and continuity of essential services; risk communication and community engagement and COVID-19 vaccination. Results: The timely establishment and activation of provincial intergovernmental and intersectoral coordinating structures led to effective coordination, resource mobilisation, leadership, decision-making and intervention. The effective communication in the department and other stakeholders resulted in improved surveillance data quality, timelier response and increased ownership of data. Dissemination, training and implementation of case management protocols ensured standardised case management. The multi-channel information dissemination targeting different audiences empowered people with real-time knowledge on the infection and encouraged health-seeking behaviours. Conclusion: The AAR demonstrated the importance of coordinated epidemiological, laboratory and communication response that requires significant public health reserve capacity in peacetime for rapid expansion in an emergency. Contribution: This review contributes to the body of knowledge emerging from the COVID-19 pandemic and provides guidance on enhanced public health response to future emergencies.

Food and nutrition security in the Philippines during the COVID-19 pandemic / Journal of Rural Medicine

Objective: The COVID-19 pandemic placed the Philippines’ food and nutrition issues front and center. In this paper, we discuss the response of its government in addressing food and nutrition security at the beginning of the COVID-19 pandemic and describe its implications on nutritional status. We also cite initiatives that address food accessibility and availability in the communities. Lastly, we explore the importance of nutrition security dimension in food security.Methods: We analyze food and nutrition security issues in the Philippines during the COVID-19 pandemic through online reports and news articles.Results: The distribution of food and financial assistance in the country was extensive, albeit insufficient, considering the prolonged lockdown restrictions. Constantly changing community quarantine guidelines have affected the movement of food supply, delivery of health services, and household economic security. Nutrition programs, such as vitamin A supplementation, feeding for children, and micronutrient supplementation for pregnant women, had lower coverage rates, and by the latter half of 2020, the country had reached its highest recorded hunger rate. Cases of both undernutrition and overnutrition are predicted to rise because of dietary imbalances and a variety of factors. Conversely, community members and some local government units took it upon themselves to improve the food situation in their areas. The provision of food packs containing fresh fruits and vegetables was lauded, as it exemplified a conscious effort to deal with nutrition security.Conclusion: Efforts to address food security have always focused on increasing accessibility, availability, and affordability, often neglecting the nutritional components of foods. Strategies that incorporate nutrition security into food security are much needed in the country, especially during emergencies like the COVID-19 pandemic.

Early prediction of severe COVID-19 in patients with Sjögren's syndrome / 北京大学学报(医学版)

OBJECTIVE@#To investigate the predictive value of blood cell ratios and inflammatory markers for adverse prognosis in patients with primary Sjögren's syndrome (PSS) combined with coronavirus disease 2019 (COVID-19).@*METHODS@#We retrospectively collected clinical data from 80 patients with PSS and COVID-19 who visited the Rheumatology and Immunology Department of the First Affiliated Hospital of Nanchang University from December 2022 to February 2023. Inclusion criteria were (1) meeting the American College of Rheumatology (ACR) classification criteria for Sjögren's syndrome; (2) confirmed diagnosis of COVID-19 by real-time reverse transcription polymerase chain reaction or antigen testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2); (3) availability of necessary clinical data; (4) age > 18 years. According to the clinical classification criteria of the "Diagnosis and Treatment Protocol for Novel Coronavirus Pneumonia (trial the 10th Revised Edition)", the patients were divided into the mild and severe groups. Disease activity in primary Sjögren' s syndrome was assessed using the European League Against Rheumatism (EULAR) Sjögren' s syndrome disease activity index (ESSDAI). Platelet-lymphocyte ratio (PLR), C-reactive protein-lymphocyte ratio (CLR), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and other laboratory data were compared between the two groups within 24-72 hours post-infection.@*RESULTS@#The mild group consisted of 66 cases with an average age of (51. 52±13. 16) years, and the severe group consisted of 14 cases with an average age of (52.64±10.20) years. Disease activity, CRP, platelets, PLR, and CLR were significantly higher in the severe group compared with the mild group (P < 0.05). Univariate analysis using age, disease activity, CRP, platelets, PLR, and CLR as independent variables indicated that disease activity, CRP, PLR, and CLR were correlated with the severity of COVID-19 (P < 0.05). Multivariate logistic regression analysis further confirmed that PLR (OR=1.016, P < 0.05) and CLR (OR=1.504, P < 0.05) were independent risk factors for the severity of COVID-19 in the critically ill patients. Receiver operator characteristic (ROC) curve analysis showed that the area under the curve (AUC) for PLR and CLR was 0.708 (95%CI: 0.588-0.828) and 0.725 (95%CI: 0.578-0.871), respectively. The sensitivity for PLR and CLR was 0.429 and 0.803, respectively, while the highest specificity was 0.714 and 0.758, respectively. The optimal cutoff values for PLR and CLR were 166.214 and 0.870, respectively.@*CONCLUSION@#PLR and CLR, particularly the latter, may serve as simple and effective indicators for predicting the prognosis of patients with PSS and COVID-19.

Uptake and impact of COVID-19 vaccination among HIV key populations: a cohort study from Tamil Nadu, India / Journal of Rural Medicine

Objective: Human Immunodeficiency Virus (HIV) Key Populations (KPs) include Female Sex Workers (FSWs), men who have sex with men (MSM), transgender (TG), and transsexual (TS) persons. This study assessed coronavirus disease 2019 (COVID-19) vaccine uptake among KPs for HIV in India, adverse events following immunization (AEFI), and breakthrough infections among the vaccinated.Materials and Methods: This retrospective cohort study was conducted among 421 KPs enrolled in 41 Targeted Intervention (TI) clusters in 31 districts of the Tamil Nadu State Acquired Immunodeficiency Syndrome (AIDS) Control Society (TANSACS), India, from June to September 2022. A semi-structured, bilingual (English and Tamil), interviewer-administered questionnaire was used to collect data on socio-demographic characteristics, vaccination status, AEFIs, and breakthrough infections among the KPs under the TIs.Results: Among the KPs, 45.4% were FSWs, 37.1% were MSM, 16.2% were TG, and 1.4% were TS persons. Among them, 4.3% had HIV, and 2.9% had syphilis or other sexually transmitted infections (STIs). The COVID-19 vaccine uptake rate was 96%. Among the KPs, TG/TS persons had the highest vaccine uptake (98.6%), followed by FSWs (96.3%) and MSM (94.2%). AEFIs were reported by 85.4% of the participants. HIV positive status was significantly associated with the incidence of AEFI. The breakthrough infection rate was 5.4% among the vaccinated participants.Conclusion: The COVID-19 vaccine uptake among HIV KPs was high in Tamil Nadu. AEFIs and breakthrough infections among COVID-19 vaccinated HIV KPs may be low, with mild AEFIs.

The disparity of utilization rate among specific groups for a rapid spreading telehealth application called LEBER during the COVID-19 state of emergency in Japan / Journal of Rural Medicine

Objectives: The purpose of this research is to describe the social demographics and chief complaints of users of a free medical consultation application in Ibaraki Prefecture, where a free medical consultation application was released.Methods: The present study included users of a telehealth application in Ibaraki Prefecture between April 9 and May 17, 2020, during the state of emergency. User background characteristics were descriptively analyzed to clarify individual factors with the potential to act as barriers to equally using innovative solutions. Additionally, the age and consultation time distribution by sex were examined for those who used the application for COVID-19 and non-COVID-19 issues.Results: Most of the participants were in their thirties. Moreover, 72% were female, with most being in their thirties (86%) and the least being in their sixties (45%). The number of consultations was concentrated between 6 p.m. and 10 p.m., with the least between 1 a.m. and 5 a.m. The telehealth application users were mainly females in their thirties and forties.Conclusions: To prevent the widening of health disparities due to the rapid introduction of telehealth, further research is required to identify why the use of the application did not spread beyond the aforementioned user groups.

TONG Xiaolin's Cold-Damp Epidemic Differentiation and Treatment Concepts and Diagnostic and Therapeutic Key Points / 中医杂志

Building on a clear understanding of the diagnosis and treatment patterns for cold-damp epidemics， and incorporating the insights of Academician TONG Xiaolin regarding the differentiation and treatment of such epidemics， this article have distilled the key diagnostic principles. These principles primarily entail observing color and pulse， initially distinguishing between yin and yang， with treatment focusing on dispelling cold and dampness. A comprehensive approach is adopted throughout treatment， with a combination of overall strategies and tailored treatments that evolve in line with the patient's condition. In critical and severe cases， particular attention is given to aspects such as sweating， pulse analysis， and consciousness， preventing the pathogen from penetrating deeply. Efforts are made to open and close organ networks， expelling external pathogens without fixating on resolving constipation. The dosage and efficacy of herbal remedies are adjusted based on individual circumstances and clinical symptoms. The objective is to eliminate pathogens comprehensively， while being vigilant against relapses， ultimately achieving a full recovery. This overview of the thought processes and clinical principles for diagnosing and treating cold-damp epidemics will guide precise clinical practices and provide a theoretical foundation for the involvement of traditional Chinese medicine in epidemic prevention and treatment.

Evolution of the newest diagnostic methods for COVID-19: a Chinese perspective / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

Coronavirus disease 2019 (COVID-19) has continued to spread globally since late 2019, representing a formidable challenge to the world's healthcare systems, wreaking havoc, and spreading rapidly through human contact. With fever, fatigue, and a persistent dry cough being the hallmark symptoms, this disease threatened to destabilize the delicate balance of our global community. Rapid and accurate diagnosis of COVID-19 is a prerequisite for understanding the number of confirmed cases in the world or a region, and an important factor in epidemic assessment and the development of control measures. It also plays a crucial role in ensuring that patients receive the appropriate medical treatment, leading to optimal patient care. Reverse transcription-polymerase chain reaction (RT-PCR) technology is currently the most mature method for detecting viral nucleic acids, but it has many drawbacks. Meanwhile, a variety of COVID-19 detection methods, including molecular biological diagnostic, immunodiagnostic, imaging, and artificial intelligence methods have been developed and applied in clinical practice to meet diverse scenarios and needs. These methods can help clinicians diagnose and treat COVID-19 patients. This review describes the variety of such methods used in China, providing an important reference in the field of the clinical diagnosis of COVID-19.

Pathological Changes and Cause of Death Associated with the Global Novel Coronavirus Disease (COVID-19) / 法医学杂志

The coronavirus disease 2019 (COVID-19) has been a global epidemic for more than three years, causing more than 6.9 million deaths. COVID-19 has the clinical characteristics of strong infectivity and long incubation period, and can cause multi-system damage, mainly lung damage, clinical symptoms of acute respiratory distress syndrome (ARDS) and systemic multiple organ damage. The SARS-CoV-2 virus is still constantly mutating. At present, there is no global consensus on the pathological changes of COVID-19 associated deaths and even no consensus on the criteria for determining the cause of death. The investigation of the basic pathological changes and progression of the disease is helpful to guide the clinical treatment and the development of therapeutic drugs. This paper reviews the autopsy reports and related literature published worldwide from February 2020 to June 2023, with a clear number of autopsy cases and corresponding pathological changes of vital organs as the inclusion criteria. A total of 1 111 autopsy cases from 65 papers in 18 countries are included. Pathological manifestations and causes of death are classified and statistically analyzed, common pathological changes of COVID-19 are summarized, and analytical conclusions are drawn, suggesting that COVID-19 infection can cause life-threatening pathological changes in vital organs. On the basis of different health levels of infected groups, the direct cause of death is mainly severe lung damage and secondary systemic multiple organ failure.

Psychological Impact of Covid-19 Pandemic on Mental Health Practitioners in Selangor, Malaysia

@#Introduction: The Coronavirus disease pandemic of 2019 (COVID-19) has had psychological implications and altered the public’s well-being. In response to the pandemic, mental health practitioners play an essential role in mitigating the adverse psychological effects among the public. However, as the demand for mental health services increases, the responsibilities of mental health professionals are far stretched from what they can handle. Therefore, this research is aimed to explore the psychological impact of the pandemic on the mental health practitioners in Selangor and their coping strategies. Method: A total of 10 mental health practitioners who are clinical psychologists and counselors participated in the one-to-one interview. The collected data were analysed using thematic analysis. Result: The higher client loads, the transition to virtual therapy, burnout, and anxiety were found to have an impact on the mental health practitioners’ well-being. Despite the challenging psychological impact, the mental health practitioners expressed a high level of satisfaction with their jobs, which they attributed to the supportive organisational culture and their intrinsic drive for selecting this profession. The mental health practitioners have reported that perceived organisational support, social support, and self-care approaches are effective coping mechanisms. Mindfulness skills such as breathing techniques and meditation are often practiced by the participants to calm the mind and body from a long day of work. Conclusion: The implication of the study contributes to breaking the stigmatisation of help seeking behaviour among the helping professions, as well as urging the policy makers, governments, and foundations to play a part in providing accessible and quality mental healthcare to the society.

Perioperative mechanical ventilation strategy for COVID-19 patients: Recommendation / 中国胸心血管外科临床杂志

@#Since December 2019, severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection has gradually spread all over the world. With the implementation of class B infectious disease management policy for coronavirus disease 2019 (COVID-19), China has experienced a pandemic. For patients receiving a time-sensitive or emergency surgery, SARS-CoV-2 infection may increase the risk of postoperative pulmonary complications. An appropriate perioperative mechanical ventilation strategy, such as lung protective ventilation strategy, is particularly important for preventing postoperative pulmonary complications in patients undergoing general anesthesia. In addition, how to protect medical personnel from being infected is also the focus we need to pay attention to. This article will discuss the perioperative mechanical ventilation strategy for COVID-19 patients and the protection of medical personnel, in order to provide reference for the development of guidelines.

A Case of Post Coronavirus Disease 2019 (COVID-19) Condition, in which the Patient Suffered from a Severe Sense of Fatigue and Brain fog Successfully Treated with Kampo Therapy / 日本東洋医学雑誌

We report a case of post coronavirus disease 2019 (COVID-19) condition, in which the patient suffered from a severe sense of fatigue and brain fog that was successfully treated with Kampo therapy. The patient was a 21-year-old man. He had been diagnosed with COVID-19 and hospitalized for follow-up examinations. He recovered without any complications and was discharged from the hospital, but continued to suffer from a severe sense of fatigue, coldness, dizziness, and a loss of concentration. Because of these symptoms, he had to spend most of the day lying down. One month later, he was hospitalized to receive Kampo therapy. We administered bukuryoshigyakuto for 2 weeks referring to his severe coldness and fatigue and then changed to renjuin for his fluid disturbance and blood deficiency. After starting Kampo therapy, his fatigue and dizziness gradually improved. He was discharged after 3 weeks of hospitalization and received Kampo therapy as an outpatient. One month later, he reported a dull feeling in his stomach and depression. We switched to kamikihitogohangekobokuto and added hachimigan. His activities of daily living improved and he could take 4.5-kilometer walk. He could return to work 4 months later. Kampo therapy may be useful for post COVID-19 condition that causes a sense of fatigue and brain fog.

Trends in Patients with Long COVID (COVID-19 Long-Term Effects) in the Kampo Outpatient Department of Infectious Diseases at Our Clinic — From Early Cases / 日本東洋医学雑誌

In response to the increasing numbers of patients with long-term effects of coronavirus disease 2019 (COVID-19), we started using Kampo (traditional Japanese) medicine for some outpatients. We analyzed the patients' characteristics and the treatments used in each case. Our subjects were 9 patients who visited our clinic between May and September 2021. All subjects provided their written informed consent and were followed for several months. Decoctions or extract formulations were prescribed for treatment based on pattern identification, and general guidance related to lifestyle habits based on traditional thought was also provided. Fatigue, lifestyle of intemperance (due to excessive amounts of cold foods and drinks), and mental/physical stress were present in each patient. Some patients also felt strong anxiety about the lack of any established Western medical treatment and insufficient follow-up systems for patients with long-term effects of COVID-19 (long COVID). Tonic formulas and formulas of involving Bupleuri radix were often used. All 9 patients showed a tendency to improve their symptoms within 4 or 5 weeks of treatment. Our impression is that the prompt effect of Kampo medicine was achieved by combining the use of Kampo medicines with instructions to stop eating excessive amounts of cold foods and/or drinks. Further study is needed in the future. For long COVID, no Western medical treatment has yet been established. On the other hand, in our experience with these patients, Kampo medicine based on the concept of mind-body unity was useful.

Relationship of health literacy with COVID-19 prevention and control knowledge, attitude and practice in general population of Baoji city / 西安交通大学学报(医学版)

【Objective】 To explore the relationship of health literacy with COVID-19 prevention and control knowledge， attitude and practice （KAP） in general population so as to contribute scientific evidence for strengthening health education and promoting health literacy to resist the threat of major infectious disease outbreaks. 【Methods】 In September 2020， a questionnaire survey was conducted in residents selected by a multi-stage random sampling across all the twelve counties/districts of Baoji city. The questionnaire， which was issued by the Chinese Health Education Center， consisted of a health literacy questionnaire and a COVID-19 prevention and control KAP questionnaire. According to the national unified scoring method， the participants were divided into two groups： those who met and those who failed to meet the overall standard of health literacy. The results of the answer to each KAP question were compared between the two groups by Chi-square test or rank sum test. Multivariate binary Logistic regression was used to control confounding effects of socio-demographic characteristics to draw relatively reliable conclusions. 【Results】 A total of 4 544 valid questionnaires were collected， in which 664 （14.60%） met the overall standard of health literacy， but 3 880 （85.40%） failed to do so. Compared with the unmet group， the met group had a higher correct answer rate in 10 of the 11 knowledge-related questions （all P<0.001）； showed more positive answer to each attitude-related question in the three aspects， namely， responsibility for the prevention and control of infectious disease transmission， evaluation for COVID-19-related information release and reporting， and evaluation for the government’s COVID-19 prevention and control results （all P<0.001）； and acted more actively in 6 of the 7 practice concerning appropriate self-prevention and control behaviors during the COVID-19 outbreak （all P<0.001）. Logistic regression analyses confirmed that achieving the overall standard of health literacy played a positive role in each of the contents of COVID-19 prevention and control KAP in study （ORs were between 1.44 and 4.09， all P<0.001）. Moreover， the absolute value of regression coefficient of the overall standard of health literacy was the largest compared with all the socio-demographic factors. Logistic regression was used to further analyze relationships between each of the six health dimensions of health literacy and COVID-19 prevention and control KAP， which revealed that the association with safety and first aid， infectious diseases prevention， and health information was the closest. 【Conclusion】 Health literacy is closely related to COVID-19 prevention and control KAP in the general population of Baoji city. Promoting residents' health literacy by targeted health education can play an important and positive role in dealing with the threat of major infectious diseases outbreaks.

Outcome of patients with severe COVID-19 pneumonia treated with high-dose corticosteroid pulse therapy: A retrospective study

Objective: To assess the effectiveness of high-dose corticosteroid pulse therapy and evaluate possible factors associated with 28-day mortality in hospitalised patients with severe COVID-19 pneumonia. Methods: We conducted a single-centre retrospective cohort study on hospitalised patients with clinical, epidemiological, and/or radiologically confirmed and suspected COVID-19 at Bitlis Tatvan State Hospital in Turkey between December 1, 2020 and June 1, 2021. All data of the study participants were recorded, and all patients received intravenous high-dose corticosteroid pulse therapy. The Ordinal Scale for Clinical Improvement (OSCI), Charlson Comorbidity Index and Total Severity Score were calculated. Univariate and multivariate Cox regression models were performed to evaluate the clinical and laboratory parameters that may affect the 28-day mortality. Results: A total of 126 patients were included in the analysis. The 28-day mortality rate of the patients was 22.2%. Laboratory and clinical improvement were observed in 77.8% (98/126) of patients after high-dose corticosteroid pulse therapy. There was a statistically significant difference between the survivors and non-survivors in terms of age, platelet count, neutrophil/lymphocyte ratio, and OSCI, Charlson Comorbidity Index, and Total Severity Score (P<0.001). Multivariate Cox regression analysis revealed that age [HR 1.047 (95% CI 1.01-1.08)], use of prophylactic anticoagulation [HR 0.838 (95% CI 0.79-0.89)], and bacterial co-infection [HR 3.966 (95% CI 1.40-11.21)] were significant determinants of mortality. Early C-reactive protein (CRP) response, decreased oxygen requirement, and improving respiratory rate/OSCI scores after administration of high-dose corticosteroid pulse therapy could contribute to clinical improvement. Conclusions: CRP response, needed oxygen and OSCI scores can be used as prognostic factors to select patients who will benefit from high-dose corticosteroid pulse therapy.

Occupational burnout analysis of border guards in the background of COVID-19 / 中国职业医学

@#Objective To analyze the occupational burnout status and its influencing factors of border guards in the prevention （ - ）Methods and control of coronavirus disease COVID 19 . A total of 1 313 border guards who participate in the prevention and control of epidemic diseases were selected as research subjects using the random cluster sampling method. Military Occupational Burnout Scale and Military Occupational Stress Scale were used to investigate the occupational burnout status and Results occupational stress in the research subjects. The median and 25th and 75th percentiles of military occupational （ ， ） （ ， ）， burnout and occupational stress total scores were 9.0 3.0 15.0 and 76.0 70.0 86.0 respectively. About 73.1% of the subjects were suffered from high occupational stress. The results of multiple linear regression analysis indicated that the higher the scores of interpersonal relationship, military special life, work pressure, unclear role and leadership ability factor in P occupational stress, and the lower the score of personal development, the more serious the occupational burnout (all <0.05 ) ， after excluding the influence of confounding factors; subjects with panic psychology inconvenience caused by closed ， management fear on accountability for poor prevention and no personal hobbies had more serious occupational burnout than （ P ） Conclusion - ， subjects without those factors all <0.05 . In the period of COVID 19 prevention the level of occupational burnout and occupational stress of border guards were generally low. The occupational burnout was mainly affected by occupational stress and fear of the epidemic.
