BackgroundThe role of hyperbaric oxygen therapy (HBOT) in necrotizing soft tissue infections (NSTI) is mainly based on small retrospective studies. A previous study using the 1998–2009 National Inpatient Sample (NIS) found HBOT to be associated with decreased mortality in NSTI. Given the argument of advancements in critical care, we aimed to investigate the continued role of HBOT in NSTI.
MethodsThe 2012–2020 National Inpatient Sample (NIS) was queried for NSTI admissions who received surgery. 60,481 patients between 2012–2020 were included, 600 ( Results
Age, gender, and comorbidities were similar between the two groups. On bivariate comparison, the HBOT group had lower mortality rate ( Conclusions
After correction for differences, HBOT was associated with decreased mortality, amputations, and non-home discharges in NSTI with the tradeoff of increase to costs and length of stay.

We implemented flipped learning for a gross anatomy dissection course and compared its effects on students’ motivation and academic achievement with those of traditional dissection methods. We invited 142 first-year medical students at Chonnam National University Medical School to participate in this study. All participants engaged in traditional dissection methods in the first part of the study and flipped learning in the latter part. Medical students’ motivation to learn anatomy by cadaveric dissection was measured using the ARCS (Attention, Relevance, Confidence, and Satisfaction) model. Thereafter, all students completed a written examination consisting of 96 multiple-choice questions. The students’ mean motivational score regarding attention was significantly higher in association with flipped learning than with traditional learning. However, the students’ mean motivational scores regarding relevance, confidence, and satisfaction were not significantly different between the methods. Additionally, the mean anatomy practice test score was significantly higher in association with flipped learning than with traditional learning. The students’ motivational scores and anatomy practice test scores associated with flipped learning positively correlated with the extent of learning material completion. The students’ responses indicated that flipped learning helped enhance the learning process, improve time management, reduce confusion during practice, and promote independent practice. The application of flipped learning to a cadaveric dissection course increased individual learning motivation, which improved learning activities both in and out of class, as well as academic achievement.by Abdou Fatawou Modiyinji, Lange Tchamba Amorgathe Tankeu, Chavely Gwladys Monamele, Moise Henri Yifomnjou Moumbeket, Paul Alain Tagnouokam Ngoupo, Huguette Tchetgna Simo, Abanda Njei Ngu, Kazanji Mirdad, Richard Njouom
BackgroundFebrile jaundice is a common indicator of certain infectious diseases, including hepatitis E. In Cameroon, the yellow fever virus is the only pathogen that is monitored in patients who present with this symptom. However, more than 90% of the samples received as part of this surveillance are negative for yellow fever. This study aimed to describe the prevalence and hepatitis E virus (HEV) genotype among yellow fever-negative patients in the Far North and West regions of Cameroon.
MethodsIn a cross-sectional study, yellow fever surveillance-negative samples collected between January 2021 and January 2023 were retrospectively analyzed. Anti-HEV IgM and IgG antibodies were tested using commercially available ELISA kits. Anti-HEV IgM and/or IgG positive samples were tested for HEV RNA by real-time RT-PCR, followed by nested RT-PCR, sequencing and phylogenetic analysis.
ResultsOverall, 121 of the 543 samples (22.3%, 95% CI: 19.0% - 26.0%) were positive for at least one anti-HEV marker. Amongst these, 8.1% (44/543) were positive for anti-HEV IgM, 5.9% (32/543) for anti-HEV IgG, and 8.3% (45/544) for both markers. A total of 15.2% (12/79) samples were positive for HEV RNA real-time RT-PCR and 8 samples were positive for HEV RNA by nested RT-PCR. Phylogenetic analysis showed that the retrieved sequences clustered within HEV genotypes/subtypes 1/1e, 3/3f and 4/4b.
ConclusionOur results showed that HEV is one of the causes of acute febrile jaundice in patients enrolled in the yellow fever surveillance program in two regions of Cameroon. We described the circulation of three HEV genotypes, including two zoonotic genotypes. Further studies will be important to elucidate the transmission routes of these zoonotic HEV genotypes to humans in Cameroon.

Recent data has characterized human milk cells with unprecedented detail and provided insight into cell populations. While such analysis of freshly expressed human milk has been possible, studies of cell functionality within the infant have been limited to animal models. One commonly used animal model for milk research is the mouse; however, limited data are available describing the composition of mouse milk. In particular, the maternal cells of mouse milk have not been previously characterized in detail, in part due to the difficulty in collecting sufficient volumes of mouse milk. In this study, we have established a method to collect high volumes of mouse milk, isolate cells, and compare the cell counts and types to human milk. Surprisingly, we found that mouse milk cell density is three orders of magnitude higher than human milk. The cell types present in the milk of mice and humans are similar, broadly consisting of mammary epithelial cells and immune cells. These results provide a basis of comparison for mouse and human milk cells and will inform the most appropriate uses of mouse models for the study of human phenomena.by Anita Kovács, Dóra Hantosi, Nikoletta Szabó, Annamária Letoha, Csaba Lengyel, Imre Földesi, Katalin Burián, András Palkó, Dániel Veréb, Zsigmond Tamás Kincses
ObjectivesEmerging results indicate that, in COVID-19, thromboembolic complications contribute to the high mortality and morbidity. Previous research showed that the prevalence of pulmonary embolism (PE) is between 25–50% in COVID-19 patients, however, most of these reports are based on data from patients with severe pneumonia, treated in intensive care units.
Materials and methodsWe conducted a retrospective, single-center, observational study to estimate the prevalence of PE in COVID-19 patients who underwent CT angiography and to identify the most important predictors.Adult outpatients with COVID-19, who presented at our COVID Outpatient Clinic between 1st and 31st of March in 2021 and underwent CTA examination were included in this study. Multiple linear regression analysis was used to identify predictors of PE in COVID-19 patients. The predictors were: age, gender, disease duration, CT severity index and log-transformed quantitative D-dimer (logQDDIM) value.
Results843 COVID-19 patients were included into the study. 82.56% (693 patients) of the infected patients had a pulmonary CTA examination and D-dimer levels (mean age: 59.82 years ± 15.66). 7.61% (53 patients) of the patients had PE. 2.02% (14 patients) of the patients had main branch or lobar PE.The multiple regression analysis found that only logQDDIM was a significant predictor. A logQDDIM cut-off value of 0.0169 (1.0171 ug/ml serum D-dimer) predicted PE with 99% sensitivity (p Conclusions
We demonstrated in a large cohort of COVID-19 patients that a cut-off value of QDDIM of 1ug/ml can exclude pulmonary embolism in an outpatient setting, implicating that QDDIM might potentially supersede CTA as a screening approach in COVID-19 outpatient clinics.

The COVID-19 pandemic has affected millions of individuals worldwide. Pain has emerged as a significant post-COVID-19 symptom. This study investigated the incidence, characteristics, and risk factors of post-COVID chronic pain (PCCP) in Thailand. A cross-sectional study was conducted in participants who had been infected, including those hospitalized and monitored at home by SARS-CoV-2 from August to September 2021. Data were collected for screening from medical records, and phone interviews were done between 3 to 6 months post-infection. Participants were classified into 1) no-pain, 2) PCCP, 3) chronic pain that has been aggravated by COVID-19, or 4) chronic pain that has not been aggravated by COVID-19. Pain interference and quality of life were evaluated with the Brief Pain Inventory and EuroQol Five Dimensions Five Levels Questionnaire. From 1,019 participants, 90% of the participants had mild infection, assessed by WHO progression scale. The overall incidence of PCCP was 3.2% (95% CI 2.3–4.5), with 2.8% (95% CI 2.0–4.1) in mild infection, 5.2% (95% CI 1.2–14.1) in moderate infection and 8.5% (95% CI 3.4–19.9) in severe infection. Most participants (83.3%) reported pain in the back and lower extremities and were classified as musculoskeletal pain and headache (8.3%). Risk factors associated with PCCP, included female sex (relative risk [RR] 2.2, 95% CI 1.0–4.9) and greater COVID-19 severity (RR 3.5, 95% CI 1.1–11.7). Participants with COVID-19-related exacerbated chronic pain displayed higher pain interferences and lower utility scores than other groups. In conclusion, this study highlights the incidence, features, and risk factors of post-COVID chronic pain (PCCP) in Thailand. It emphasizes the need to monitor and address PCCP, especially in severe cases, among females, and individuals with a history of chronic pain to improve their quality of life in the context of the ongoing COVID-19 pandemic.by Mira Puthettu, Stijn Vandenberghe, Spyros Balafas, Clelia Di Serio, Geni Singjeli, Alberto Pagnamenta, Stefanos Demertzis
Although CO2 field-flooding was first used during cardiac surgery more than 60 years ago, its efficacy is still disputed. The invisible nature of the gas and the difficulty in determining the “safe” quantity to protect the patient are two of the main obstacles to overcome for its validation. Moreover, CO2 concentration in the chest cavity is highly sensitive to procedural aspects, such suction and hand movements. Based on our review of the existing literature, we identified four major factors that influence the intra-cavity CO2 concentration during open-heart surgery: type of delivery device (diffuser), delivery CO2 flow rate, diffuser position around the wound cavity, and its orientation inside the cavity. In this initial study, only steady state conditions were considered to establish a basic understanding on the effect of the four above-mentioned factors. Transient factors, such as suction or hand movements, will be reported separately.by Caterina Casalini, Yema D’Almeida, Moussa Ariziki Nassam, Essopha Kokoloko, Souley Wade, Jean Paul Tchupo, Messan Damarly, Justin Mandala, Michele Lanham, Natasha Mack, Chris Akolo, Vincent Polakinam Pitche, Hugues Guidigbi, Claver Anoumou Dagnra
BackgroundAccording to UNAIDS, Togo halved AIDS-related deaths among children ages 0–14 from 2010 to 2020. However, available data show low dolutegravir (DTG)-containing antiretroviral therapy (ART) coverage and low viral load suppression (VLS) among children living with HIV (CLHIV). We analyzed routine facility data before and after implementation of root-cause-based solutions for improving DTG coverage, viral load (VL) testing coverage, and VLS among CLHIV.
DescriptionWe analyzed routine data for CLHIV ≤14 years from October 2019 through September 2022. We assessed proportion of CLHIV on ART receiving DTG, VL testing coverage (CLHIV on ART with documented VL test result), and VLS (CLHIV with documented VL test result of Results
From baseline (October 2019–September 2020) to endline (October 2021–September 2022), increases were observed for DTG coverage (52% to 71%), VL testing coverage (48% to 90%), and VLS (64% to 82%). Age-disaggregated data showed positive trends.
ConclusionsRoot-cause-based solutions and granular data use increased DTG coverage, resulting in increased VL testing and VLS among CLHIV. These interventions should be scaled and become the national standard of care.

BackgroundGrowing attention is paid to the association between alterations in the gut microbiota and their metabolites in patients with psychiatric disorders. Our study aimed to determine how gut microbiota and metabolomes are related to the sleep quality among patients with depression and anxiety disorders by analyzing the datasets of our previous study.
MethodsSamples were collected from 40 patients (depression: 32 patients [80.0%]); anxiety disorders: 8 patients [20.0%]) in this study. Gut microbiomes were analyzed using 16S rRNA gene sequencing and gut metabolomes were analyzed by a mass spectrometry approach. Based on the Pittsburgh Sleep Quality Index (PSQI), patients were categorized into two groups: the insomnia group (PSQI score ≥ 9, n = 20) and the non-insomnia group (PSQI score Results
The insomnia group showed a lower alpha diversity in the Chao1 and Shannon indices than the non-insomnia group after the false discovery rate (FDR) correction. The relative abundance of genus Bacteroides showed a positive correlation with PSQI scores in the non-insomnia group. The concentrations of glucosamine and N-methylglutamate were significantly higher in the insomnia group than in the non-insomnia group.
ConclusionsOur findings suggest that specific taxa could affect the sleep quality among patients with depression and anxiety disorders. Further studies are needed to elucidate the impact of sleep on specific gut microbiota and metabolomes in depression and anxiety disorders.

Social media platforms are common means of sharing information, personal experiences, and lifestyle. They can also be utilized as cost-effective methods for individuals to acquire health information and promote oral health. The purpose of the present study was to systematically review the current literature on the interventions taken through social media for promoting lay people’s oral health. This systematic review (PROSPERO: CRD42023395005) followed the preferred reporting items for systematic reviews and meta-analyses (PRISMA) 2020 guidelines. A comprehensive search was conducted in four electronic databases (PubMed, Scopus, Embase, and Cochrane Library) for relevant articles published between 2012 and 2023. Data such as study design, sample size, follow-up duration, utilized social media platforms and main findings were extracted from the eligible studies. The quality of the studies included in the systematic review was evaluated by the quality assessment tools for intervention studies recommended by the National Collaborating Centre for Methods and Tools. Out of the 1934 records identified in the initial search, 10 studies met the inclusion criteria and were included in the qualitative synthesis. These studies comprised seven randomized control trials, one field trial and two quasi-experimental. Various social media platforms, including Telegram, Instagram, YouTube, WhatsApp and Snapchat, were used for communication with patients. Some studies solely utilized social media interventions, while others combined online and traditional interventions. The quality assessment categorized 30% of the studies as “strong”, 50% as “moderate”, and the remaining as “weak”. The implementation of social media interventions positively influenced multiple aspects of oral health among the laypeople. Online platforms such as YouTube, WhatsApp, Instagram, and Telegram can be effectively utilized to promote oral health among patients.by Susan Nakireka, David Mukunya, Crescent Tumuhaise, Ronald Olum, Edith Namulema, Agnes Napyo, Quraish Serwanja, Prossie Merab Ingabire, Asad Muyinda, Felix Bongomin, Milton Musaba, Vivian Mutaki, Ritah Nantale, Phillip Akunguru, Rozen Ainembabazi, Derrick Nomujuni, William Olwit, Aisha Nakawunde, Specioza Nyiramugisha, Pamela Mwa Aol, Joseph Rujumba, Ian Munabi, Sarah Kiguli
BackgroundIn Uganda, approximately 170,000 confirmed COVID-19 cases and 3,630 deaths have been reported as of January 2023. At the start of the second COVID-19 wave, the Ugandan health system was overwhelmed with a sudden increase in the number of COVID-19 patients who needed care, and the Ministry of Health resorted to home-based isolation and care for patients with mild to moderate disease. Before its rollout, the COVID-19 home-based care strategy had neither been piloted nor tested in Uganda.
ObjectiveTo explore the experiences of COVID-19 patients managed at home in Uganda.
MethodsThis was a qualitative study that was conducted to explore the lived experiences of COVID-19 patients managed at home. The study was carried out among patients who presented to three hospitals that were designated for treating COVID-19 patients in Uganda. COVID-19 patients diagnosed at these hospitals and managed at home were followed up and contacted for in-depth telephone interviews. The data were analysed using thematic content analysis with the aid of NVIVO 12.0.0 (QRS International, Cambridge, MA).
ResultsParticipants experienced feelings of fear and anxiety: fear of death, fear of losing jobs, fear of infecting loved ones and fear of adverse events such as loss of libido. Participants also reported feelings of loneliness, hopelessness and depression on top of the debilitating and sometimes worsening symptoms. In addition to conventional medicines, participants took various kinds of home remedies and herbal concoctions to alleviate their symptoms. Furthermore, COVID-19 care resulted in a high economic burden, which persisted after the COVID-19 illness. Stigma was a major theme reported by participants. Participants recommended that COVID-19 care should include counselling before testing and during and after the illness to combat the fear and stigma associated with the diagnosis. Another recommendation was that health workers should carry out home visits to patients undergoing home-based care and that COVID-19 treatment should be free of charge.
ConclusionCOVID-19 home-based care was associated with fear, anxiety, loneliness, depression, economic loss and stigma. Policymakers should consider various home-based follow-up strategies and strengthen counselling of COVID-19 patients at all stages of care.

Lifetime exposures to violence among men who have sex with men (MSM) are associated with multiple psychosocial health risks and can affect engagement and outcomes of HIV treatment. This study a) explored relationships between levels of exposures to violence and HIV care continuum outcomes among MSM living with HIV in India, and b) identified psychosocial correlates of HIV care continuum outcomes among MSM living with HIV and those with lifetime cumulative exposures to violence (CVE). CVE referred to exposures to violence in both childhood and adulthood. This cross-sectional analysis used survey data collected between August 2016 and May 2017 from 1763 men who have sex with men living with HIV across 10 cities in India, using respondent-driven sampling. We found that higher levels of violence exposure were significantly associated with lower awareness of HIV positive status, and lower likelihood of initiating antiretroviral therapy. Compared with MSM living with HIV that had no CVE, those with CVE were more likely to report perpetration of interpersonal violence, alcohol misuse, depressive symptoms, and HIV transmission risk behaviors and to have two to four co-occurring psychosocial problems. In multivariable analysis with the subset of MSM with CVE, psychosocial correlates significantly associated with at least one HIV care continuum outcome were HIV transmission risk behaviors, perpetration of interpersonal violence, depression, and alcohol misuse. The findings highlight the need for integrating care for lifetime violence exposures and associated behavioral problems in HIV care settings for men who have sex with men living with HIV in India.by Sabuj Kanti Mistry, A.

ObjectiveThe present study aims to measure the prevalence of non-disabled frailty and its associated factors among Bangladeshi older adults.
MethodsThis cross-sectional study was conducted during September and October 2021 among 1,045 Bangladeshi older adults (≥60 years). Telephone interviews, using a semi-structured questionnaire, were undertaken to collect data on participants’ characteristics and level of frailty. The non-disabled frailty was measured using the ‘Frail Non-Disabled (FiND)’ questionnaire. A multinomial logistic regression model assessed the factors associated with frailty among the participants.
ResultsAround a quarter of the participants (24.8%) were frail. The multinomial regression analysis showed that older participants aged ≥80 years (RRR = 3.23, 95% CI: 1.41–7.37) were more likely to be frail compared to participants aged 60–69 years. Likewise, the participants living in a large family with ≥4 members (RRR = 1.39, 95% CI: 1.01–1.92) were more likely to be frail compared to those living in smaller families. Also, participants having memory or concentration problems (RRR = 1.56, 95% CI: 1.12–2.17) were more likely to be frail compared to those who were not suffering from these problems. Moreover, participants whose family members were non-responsive to their day-to-day assistance (RRR = 1.47, 95% CI: 1.06–2.03) were more likely to be frail compared to those whose family members were responsive. Furthermore, participants who were feeling lonely (RRR = 1.45, 95% CI: 1.07–1.98) were more likely to be frail than their counterparts who were not feeling lonely.
ConclusionsThe findings of the present study suggest developing tailored interventions to address the burden of frailty among the older populations in Bangladesh. In particular, providing long-term care and health promotion activities can be of value in preventing frailty and reducing adverse health outcomes among this vulnerable population group.

Positive psychological well-being has a favorable impact on survival rates in both healthy and unhealthy populations. Oral health is also associated with psychological well-being, is multidimensional in nature, and includes physical, psychological, emotional, and social domains that are integral to overall health and well-being. This study aimed to identify the associations between individual and environmental characteristics, oral condition and nutritional status in relation to subjective well-being among older adults using the Wilson and Cleary conceptual model. The participants were older adults (age ≥ 60 years) attending a university hospital. Subjective well-being was assessed using the World Health Organization-5 Well-Being Index, oral condition was assessed based on the number of bacteria in the tongue coating, oral wettability, tongue pressure, occlusal force, oral diadochokinesis, and masticatory ability, and subjective swallowing function was assessed using the Eating Assessment Tool, number of remaining teeth, and number of functional teeth. In addition, factors related to well-being, including social networks, life–space mobility, nutritional status, smoking history, drinking history, and medical history were assessed. In the analysis, structural equation modeling was used to investigate the association between oral condition and subjective well-being. Confirmatory factor analysis revealed oral condition as a latent variable, including tongue pressure, oral diadochokinesis /pa/, /ta/, /ka/, occlusal force, masticatory ability, subjective swallowing function, and number of functional teeth. Structural Equation Modeling revealed that oral condition was positively correlated with nutritional status, and nutritional status was positively correlated with the World Health Organization-5 Well-Being Index. These findings suggest that oral condition may influence subjective well-being via nutritional status or social environmental factors.by Hyoung Nam Lee, Sangjoon Lee, Sung-Joon Park, Youngjong Cho, Hwan Hoon Chung
Bedside peripherally inserted central catheter (PICC) placement is sometimes required when the patient’s intrahospital transport is restricted, and the ideal catheter length prediction is needed. This study aimed to develop an updated formula that predicts the optimal length of a PICC based on anteroposterior chest radiographs (AP-CXRs). This retrospective study collected PICC procedure data as the training and validation sets in three hospitals, including cubital crease-puncture point distance (CP), the actual PICC length (aCL), and the approach side. Horizontal and vertical measurement variables were set on the AP-CXRs. Two dependent variables were ipsilateral upper arm length (AL) and ideal truncal catheter length (iTCL). Simple and multiple regression analyses were used for formula development, and it was applied to the test set to evaluate the length prediction performance. The study included 309 patients in the training and validation sets and 91 intensive care patients in the test set. The final derived formula was: (AL + iTCL = CP + estimated PICC length, cm) = 19.831 − 0.062 × (contralateral clavicle length, cm) + 0.255 × (2nd ribs horizontal distance, cm) + 0.720 × (humero-vertebral distance, cm) + 0.761 × (thoraco-carinal distance, cm) + 1.024 × (the vertical distance of two vertebral body units, cm). (If approaching from the left, add 2.843cm, and if female, subtract 0.821cm.) In the test set, there was no case of length prediction failure. Moreover, the catheter tip position was evaluated as optimal in 82 cases (90.1%). This study’s results suggest an updated formula to predict the ideal PICC length using only AP-CXRs for bedside placement.by Sadegh Moradi Vastegani, Seyed Esmaeil Khoshnam, Samireh Ghafouri, Nima Bakhtiari, Yaghoob Farbood, Alireza Sarkaki
IntroductionAnethole is the main compound of the essential oil of anise and several other plants, which has antioxidant, anti-inflammatory, and neuroprotective properties. Oxidative stress is considered as an important factor in the pathogenesis of PD. In the present study, we aimed to investigate the effects of anethole against rotenone-induced PD.
MethodsMale Wistar rats were randomly divided into six groups. Control group received DMSO + sunflower oil, model group received rotenone (2 mg/kg, s.c, daily for 35 days), positive control group received L-Dopa, and test groups received anethole (62.5, 125, and 250 mg/kg, i.g, daily for 35 days) 1 hour before each rotenone injection. Body weight changes, rotarod test, stride length test, and extracellular single unit recording were performed after treatment. After behavioral test, Brain water content and blood brain barrier (BBB) permeability were evaluated, and the levels of malondialdehyde (MDA), superoxide dismutases (SOD), alpha-synuclein and MAO-B were measured in the striatum.
ResultsChronic administration of rotenone induced body weight loss and caused significant dysfunction in locomotor activity, neuronl firing rate, and BBB. Rotenone also decreased SOD activity, increased MDA level, and elevated the expression of alpha-synuclein and MAO-B in the striatum. However, treatment with anethole attenuated body weight loss, motor function, neuronal activity, and BBB function. Furthermore, Anethole treatment attenuated oxidative stress and decreased the expression of alpha-synuclein and MAO-B compared to the rotenone group.
ConclusionOur results show that through its antioxidant properties, aethole can improve the cellular, molecular and behavioral characteristics of rotenone-induced Parkinson’s disease.

PurposeThis study aimed to identify the association between physical activity and health-related quality of life (HRQoL) in middle-aged and elderly individuals with musculoskeletal disorders.
MethodsThis study used data from the 2016–2020 Korea National Health and Nutrition Examination Survey (KNHANES). We included only those over 40 years of age diagnosed with one or more of the following: osteoarthritis, rheumatism, and osteoporosis. In total, 4,731 participants (783 men and 3,948 women) were included as the study population. Multiple logistic regression analysis was performed to examine the association between physical activity and HRQoL.
ResultsIn the case of middle-aged and elderly individuals with musculoskeletal disorders, the likelihood of HRQoL worsening was significantly lower for those who regularly engaged in physical activity compared with that of those who did not engage in physical activity at all (men: OR 0.58, 95% CI 0.37–0.90; women: OR 0.64, 95% CI 0.53–0.79). Stratified analysis by the type and intensity of physical activity revealed that the possibility of poor HRQoL was lowest when leisure-related moderate-intensity physical activities were performed (men: OR 0.44, 95% CI 0.22–0.89; Women: OR 0.50, 95% CI 0.36–0.69).
ConclusionsOur findings suggest that engaging in regular physical activity contributes to preventing exacerbation of HRQoL, even if the individual suffers from musculoskeletal disorders. It is necessary to provide an appropriate type and intensity of physical activity in consideration of the patients’ pain and severity.
