Changing patterns in the distribution of skin lesions of scabies during the COVID-19 pandemic - a cross-sectional observational study

BACKGROUND: An ectoparasitic disease, scabies, caused by the mite Sarcoptes scabiei var hominis. Some of the predisposing factors are overcrowding, unhygienic surroundings, immunocompromised status, dementia, homelessness, and sexual contact. In this study, we wanted to evaluate the changed distribution of lesions of scabies during pandemic. METHODS: A cross sectional study was performed on 600 patients attending the skin department of our tertiary care hospital over a period of 6 months. The sites of the scabies lesions were noted along with types of lesions. Demographic data and history of regular hand washing and sanitization were also documented. RESULTS: Our study revealed an important correlation between change in pattern of distribution of scabies lesions from being less frequent on finger webs (19%) to being more frequent on abdomen (periumbilical area) (73%) and groins (67%) due to regular hand washing and frequent sanitization, in this pandemic era. CONCLUSIONS: A significant change in distribution of skin lesions in scabies can be noticed during this COVID-19 pandemic.

Participatory Action Research and climate change in indigenous territories of the Huasteca Hidalguense

The objective of this work is to analyze the specific impacts of climate change in the Huasteca Hidalguense, an indigenous region of the state of Hidalgo that, according to the State Action Program for Climate Change (Otazo, 2011), will be the most affected in terms of temperature increase, water availability, food production and health in the decade 2020-2030. To obtain the information, a Participatory Action Research (PAR) process was carried out, culminating in the "Regional Forum on Water, Biodiversity and Climate Change in the Huasteca Hidalguense" and the workshop "Past, present and future of our territory". These activities showed that since the 1980s, a series of endogenous and exogenous impacts have been occurring in three ejidos in the municipality of Atlapexco that have impacted water availability, sanitation, deterioration of natural resources, and rising temperatures. The unexpected irruption of the Covid 19 pandemic implied difficulties in influencing the elaboration of collaborative measures among different actors to act in the face of the impacts of this phenomenon. Despite the above, we concluded that it is necessary to promote PRA processes to strengthen water infrastructure in indigenous territories highly vulnerable to climate change to build participatory solutions to the problems identified.

Para obtener la información se llevó a cabo un proceso de Investigación Acción Participativa (IAP) que culminó con la realización del "Foro Regional Agua, Biodiversidad y Cambio Climático en la Huasteca Hidalguense" y del taller "Pasado, presente y futuro de nuestro territorio". A través de dichas actividades se comprobó que, desde los años 80 del siglo pasado, tres ejidos del municipio de Atlapexco han experimentado una serie de impactos endógenos y exógenos que impactan en la disponibilidad de agua, el saneamiento, el deterioro de los recursos naturales y el aumento de las temperaturas. La irrupción inesperada de la pandemia de Covid 19 implicó dificultades para incidir en la elaboración de medidas colaborativas entre distintos actores para actuar ante las incidencias de este fenómeno. A pesar de lo anterior, se concluye que es necesario impulsar procesos de IAP para fortalecer la infraestructura hídrica en territorios indígenas altamente vulnerables al cambio climático, con la finalidad de construir soluciones participativas a las problemáticas identificadas.

Environmental hygiene in outdoor food markets in Africa: a scoping review

Outdoor food markets represent important locations where foodborne illnesses and other infectious diseases can spread. Countries in Africa face particular challenges given the importance of these markets in food supply and low rates of access to safely managed water and sanitation. We undertook a scoping review of evidence related to disease transmission in food markets in sub-Saharan Africa, North Africa and identified 46 papers for data extraction and synthesis. Vendor behaviour or awareness was reported in the majority of papers and about half reported on market infrastructure. Fewer studies have been reported on regulatory environments or food contamination. Studies on water supply, sanitation and handwashing facilities focused on the presence of services and did not evaluate quality, thus conclusions cannot be drawn on service adequacy. Studies of vendor behaviour were primarily based on self-reporting and subject to bias. Most studies reported high levels of vendor awareness of the need for hygiene, but where observations were also conducted, these showed lower levels of behaviours in practice. Our findings suggest that there are limited studies on environmental hygiene in outdoor food markets and this is an area warranting further research, including into the quality of services and addressing methodological weaknesses.

Exploratory Factorial Model of Hydric Conservation in the COVID-19 era

Scenarios of scarcity, shortages, healthiness and scarcity are proposed to which HEIs would react, but with nuances according to the capacities of the areas of knowledge such as the case of health sciences and administrative economic sciences. [...]a Modeling is a mapping of the variables indicative of a behavior based on inclusion criteria such as the consensus of the literature regarding the SDG-6 and its observation in HEIs. [...]verifiability frameworks prevail in the biological and health sciences. [...]a comparison between different sources observing the same phenomenon generates the veracity of a data [9]. The IES only covers a few disciplines that respond to the development needs of the region, as well as the projected labor demand [10]. [...]the objective of this work is to contribute with empirical evidence to the SDG indicators: scarcity, drought, depletion, sanitation, purification, quality and floods [11].

Structure characteristics and development sustainability of municipal solid waste treatment in China

This study aims to analyze the development trend of municipal solid waste (MSW) treatment in China from 2011 to 2020, and provide insights into the challenges and opportunities of sustainable MSW management. Our analysis shows that MSW generation declined in 2020, which could be attributed to a combination of factors, including the low urban population growth rate, the implementation of the garbage classification policy, and the impact of the COVID-19 pandemic. We also found that the shift from landfill to incineration is expected to increase significantly in the coming years, although there are still several structural problems, such as an imbalance in treatment capacity among regions and cities, and uncertainty about whether the increase in incineration treatment capacity can meet overall demand due to the high volume of MSW generation. Our analysis highlights the heavy dependence on government investment for MSW treatment mode change, which is difficult due to the expanding deficit between fiscal revenue and expenditure of local governments. Correlation coefficient analysis shows a significant positive correlation between the proportion of incineration and sanitation investment, and a significant negative correlation between the proportion of landfill treatment and sanitation investment. To address these challenges, we propose technological advancement and management optimization to reduce the cost of MSW treatment, as well as expansion of investment channels through green funds, taxation relief, and other means to promote high-quality and sustainable development of the MSW treatment industry. These changes could accelerate the transformation of China's MSW treatment industry from policy promotion-dependent to market-oriented sustainable operation.

Implications on Gender During the Pandemic

The Novel Coronavirus has hardly left any corner of the society and economy untouched. Apparently, response to the pandemic across the globe and its impact on society and economy are clearly dependent on the pre-existing social economic and cultural setup of the nation. Among others, the fear of the pandemic reversing the state of human security achieved in the past two decades, stays strong, specifically the one associated with gender. In this context, the chapter taking the case of women working in the formal sector and those living in slums of informal settlement attempts to locate the gender response to human security in the urban setup of Bengaluru, India. The analysis based on field insights backed by secondary literature helps us to argue that gender dimensions of pandemic and its response indeed need due acknowledgement of the situation and also sensitization to prevent its multiplier effect in due course of time. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer 2022.

Impact of anti-epidemic measures on the dynamics of the incidence of COVID-19 in medical organizations with a psychoneurological profile

Aim of the study was to evaluate the impact of anti-epidemic measures (CAM) complex on the dynamics of the epidemic process of COVID-19 in a controlled cohort of patients. Material and methods. Patients from 30 social long-term care institutions of the city were included in the study, including neuropsychiatric boarding schools, boarding houses for labor veterans, gerontological centers, and houses for stage veterans. A total of 8303 patients participated in the study, of which 4237 were men (mean age 53.6 years) and 4066 were women (mean age 62.0 years). Vaccination was carried out with Gam-Covid-Vac. Results and discussion. For the entire observation period from March 2020 to August 2021, 1619, cases of COVID-19 or 19.5% of the total number of patients were registered among patients. At the initial epidemic stage (spring-summer 2020), the incidence of COVID-19 among patients was explosive. At the same time, in the autumn-winter period of 2020, an increase in the incidence of COVID-19 was also observed. However, much less pronounced than in April 2020. Despite the progress, it was decided to strengthen the sanitary and anti-epidemic regime in institutions with the introduction of additional preventive measures. One of the most effective long-term algorithms for reducing the infectious disease incidence was vaccination. In this regard, the Moscow Department of Healthcare suggested the need for voluntary vaccination of 100% of patients in all institutions at the beginning of 2021. In the spring of 2021, the number of cases began to increase in the city. The increase in the incidence of COVID-19 was insignificant among the patients of institutions: the maximum number of cases detected in one month during this period was 13 people (in April), or 60.5 times less than in April 2020, and 2.5 times less than in October 2020. The incidence of COVID-19 has become sporadic rather than epidemic. Conclusion. The introduction of CAM in long-term care social institutions in the early stages of the epidemic contributed to a decrease in the incidence of COVID 19. 100% vaccination of patients in combination with other prevention measures reduced the incidence of COVID-19 by more than 28 times. At the same time, it was found that there is a trend of increasing incidence depending on the increase in the level of independent activity of patients.Copyright © 2023 The authors.

Placing Antimicrobial Resistance in the Context of Competing Public Health Priorities in Sub-Saharan Africa, a Perspective from Malawi

Antimicrobial resistance is a major threat to human health that is predicted to impact most heavily on sub-Saharan Africa, however there is a lack of clinical outcome data from drug-resistant infections in this setting. There are reasons to expect the COVID-19 pandemic to have both positive and negative impacts on AMR in Africa. We have recruited a series of prospective longitudinal cohorts from Queen Elizabeth Central Hospital (QECH), Blantyre, Malawi and the surrounding communities in the Southern Region of Malawi. The data from these cohorts has been used to describe the aetiology of febrile illness, the burden of antimicrobial resistance in this setting and the distribution of extended spectrum beta-lactamase producing bacteria in humans, animals and the environment. Amongst a cohort of patients presenting to QECH unwell with febrile illness, 67% were living with human immunodeficiency virus (HIV). We identified a diagnosis in 145 of 225 (64%) participants, most commonly tuberculosis (TB;34%) followed by invasive bacterial infections (17%), arboviral infections (13%), and malaria (9%). In a second cohort with drug resistant infection, resistance to third-generation cephalosporins was associated with an increased probability of in-hospital mortality (hazard ratio [HR] 1.44, 95% CI 1.02-2.04), longer hospital stays (1.5 days, 1.0-2.0) and decreased probability of discharge alive (HR 0.31, 0.22-0.45). In the community cohorts, a paucity of environmental health infrastructure and materials for safe sanitation was identified across all sites and ESBL-Enterobacterales were isolated from 41.8% of human stool, 29.8% of animal stool and 66.2% of river water samples and was associated with the wet season, living in urban areas, advanced age and in household-animal interactions. Life threatening febrile illness is common in Blantyre however, diagnostics are few, however the COVID-19 pandemic has led to rapid expansion of diagnostic capacity. We are, however frequently treating the wrong bugs with ceftriaxone, further there was significant expansion of azithromycin demand and usage during the pandemic. Current management of sepsis has not been optimised and ceftriaxone use is promoting carriage of ESBL bacteria out of the hospital and ESBL E. coli and K. pneumoniae are ubiquitous in the community, where environmental hygiene infrastructure and community antimicrobial stewardship are critically lacking.Copyright © 2023

Potential Use of a Combined Bacteriophage-Probiotic Sanitation System to Control Microbial Contamination and AMR in Healthcare Settings: A Pre-Post Intervention Study.

Microbial contamination in the hospital environment is a major concern for public health, since it significantly contributes to the onset of healthcare-associated infections (HAIs), which are further complicated by the alarming level of antimicrobial resistance (AMR) of HAI-associated pathogens. Chemical disinfection to control bioburden has a temporary effect and can favor the selection of resistant pathogens, as observed during the COVID-19 pandemic. Instead, probiotic-based sanitation (probiotic cleaning hygiene system, PCHS) was reported to stably abate pathogens, AMR, and HAIs. PCHS action is not rapid nor specific, being based on competitive exclusion, but the addition of lytic bacteriophages that quickly and specifically kill selected bacteria was shown to improve PCHS effectiveness. This study aimed to investigate the effect of such combined probiotic-phage sanitation (PCHSφ) in two Italian hospitals, targeting staphylococcal contamination. The results showed that PCHSφ could provide a significantly higher removal of staphylococci, including resistant strains, compared with disinfectants (-76%, p < 0.05) and PCHS alone (-50%, p < 0.05). Extraordinary sporadic chlorine disinfection appeared compatible with PCHSφ, while frequent routine chlorine usage inactivated the probiotic/phage components, preventing PCHSφ action. The collected data highlight the potential of a biological sanitation for better control of the infectious risk in healthcare facilities, without worsening pollution and AMR concerns.
