Abstract
Background
The coronavirus disease 2019 (COVID-19) pandemic continues to evolve. Globally, COVID-19 continues to strain even the most resilient healthcare systems, with Omicron being the latest variant. We made a thorough search for literature describing the effects of the COVID-19 in a high human immunodeficiency virus (HIV)/tuberculosis (TB) burden district-level hospital setting. We found scanty literature.

Methods
A retrospective observational study was conducted at Khayelitsha District Hospital in Cape Town, South Africa (SA) over the period March 2020–December 2021. We included confirmed COVID-19 cases with HIV infection aged from 18 years and above. Analysis was performed to identify predictors of mortality or hospital discharge among people living with HIV (PLWH). Predictors investigated include CD4 count, antiretroviral therapy (ART), TB, non-communicable diseases, haematological, and biochemical parameters.

Findings
This cohort of PLWH with SARS-CoV-2 infection had a median (IQR) age of 46 (37–54) years, male sex distribution of 29.1%, and a median (IQR) CD4 count of 267 (141–457) cells/mm3. Of 255 patients, 195 (76%) patients were discharged, 60 (24%) patients died. One hundred and sixty-nine patients (88%) were on ART with 73(28%) patients having acquired immunodeficiency syndrome (AIDS). After multivariable analysis, smoking (risk ratio [RR]: 2.86 (1.75–4.69)), neutrophilia [RR]: 1.024 (1.01–1.03), and glycated haemoglobin A1 (HbA1c) [RR]: 1.01 (1.007–1.01) were associated with mortality.

Conclusion
The district hospital had a high COVID-19 mortality rate among PLWH. Easy-to-access biomarkers such as CRP, neutrophilia, and HbA1c may play a significant role in informing clinical management to prevent high mortality due to COVID-19 in PLWH at the district-level hospitals.

Published: March 2023

Abstract
Background
The surveillance of hospital-acquired infections in Germany is usually conducted via manual chart review; this, however, proves resource intensive and is prone to a certain degree of subjectivity. Documentation based on electronic routine data may present an alternative to manual methods. We compared the data derived via manual chart review to that which was derived from electronic routine data.

Methods
Data used for the analyses was obtained from five of the University of Leipzig Medical Center’s (ULMC) ICUs. Clinical data was collected according to the Protection against Infection Act (IfSG); documentation thereof was carried out in hospital information systems (HIS) as well as in the ICU-KISS module provided by the National Reference Center for the Surveillance of Nosocomial Infections (NRZ). Algorithmically derived data was generated via an algorithm developed in the EFFECT study; ward-movement data was linked with microbiological test results, generating a data set that allows for evaluation as to whether or not an infection was ICU-acquired.

Results
Approximately 75% of MDRO cases and 85% of cases of sepsis/primary bacteremia were classified as ICU-acquired by both manual chart review and EFFECT. Most discrepancies between the manual and algorithmic approaches were due to differentiating definitions regarding the patients’ time at risk for acquiring MDRO/bacteremia.

Conclusions
The concordance between manual chart review and algorithmically generated data was considerable. This study shows that hospital infection surveillance based on electronically generated routine data may be a worthwhile and sustainable alternative to manual chart review.
Multisystem inflammatory syndrome in children associated with Bacille Calmette-Guérin scar: a case presentation

Published: March 2023

Abstract
Background
During Coronavirus disease of 2019 (COVID-19) pandemic, the WHO reported a noticeable increase in Kawasaki disease prevalence in countries where Kawasaki disease is rare. This newly seen disease, unlike typical Kawasaki disease, tends to appear at a later age, has prominent gastrointestinal findings, higher rates of myocarditis and coronary artery involvement and a greater need for admission to the intensive care unit (ICU). Induration of the Bacillus Calmette-Guerin (BCG) scar is a rare finding seen in multisystem inflammatory syndrome (MIS-C). This is the second reported case of erythema and induration of the BCG scar in a 1-year-old boy with MIS-C.

Case presentation
The Arabic boy presented with high resistant fever, nausea/vomiting, diarrhea, erythematous lips, and conjunctivitis. He later developed induration of his BCG scar, diffuse rash and desquamation on fingers and toes. He had a history of COVID-19 exposure as his IgG antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) were positive. Based on his clinical findings and repeated lab results, he was diagnosed with MIS-C with Kawasaki features and treated with intravenous immune globulin (IVIG) followed by methylprenisolone and aspirin.

Conclusions
Reaction at the BCG inoculation site is not a diagnostic criteria for Kawasaki, but it is seen clinically in 30-50% of the patients. We report the case of a 1-year-old boy diagnosed with MIS-C presenting with erythema and induration of BCG scar. Further studies are needed to explore this clinical presentation, especially in the countries that have BCG vaccination programs, and to determine the mechanisms of MIS-C.
Failure to diagnose hypochondroplasia by prenatal diagnosis: a case report
Authors: Xie Hua , Chen Yulin , Xiong Fei , Li Jinrong , Yang Fan 
Published: March 2023

Abstract
Background
Hypochondroplasia (HCH) is a common nonlethal skeletal dysplasia caused by pathogenic variations in the fibroblast growth factor receptor 3 (FGFR3) gene, and HCH has similar clinical manifestations with achondroplasia (ACH), which can be screened during the fetal period by prenatal ultrasound testing and diagnosed by genetic testing.

Case presentation
we report the special case of a patient with obvious growth retardation and rhizomelic disproportionate short stature, accompanied by other manifestations, including an enlarged head and short hands at 1 year old. However, several multiple color ultrasound exams identified shortened limbs (< 3rd percentile), an increased biparietal diameter (> 95th percentile) and a low nasal bridge in the fetal period. Due to the high incidence rate of ACH, genetic testing for the hotspot FGFR3 gene c.1138 g > A pathogenic variations was performed immediately in the third trimester. Unfortunately, the definitive diagnosis could not be made before birth due to the negative result of hotspot gene exam. Whole exome sequencing (WES) was performed at 1 year identified FGFR3 gene c.1620C > A variations positivity, and the patient was finally diagnosed as HCH.

Conclusion
Our report extends the understanding of the limitations of prenatal genetic diagnostic testing, especially the hot spot pathogenic variations test should be not the only clinical diagnostic basis. Moreover, this case also emphasizes that further gene analysis for patients with significant conflict between the clinical manifestation and the prenatal genetic panel examination findings should be reconducted timely to spare the family from a delayed diagnosis or a misdiagnosis.
Development and initial evaluation of a behavioural intervention to support weight management for people with serious mental illness: an uncontrolled feasibility and acceptability study
Authors: Lee Charlotte , Waite Felicity , Piernas Carmen , Aveyard Paul 
Published: March 2023

Abstract
Background
The rates of obesity and associated health problems are higher in people with serious mental illness (SMI), such as schizophrenia and bipolar disorder, than the general population. A primary care referral to a behavioural weight management programme can be an effective intervention, but people with SMI have reported barriers to engaging with them and bespoke options are rarely provided in routine practice. It is possible that adjunct support addressing these specific barriers could help. Here we report the development, feasibility and acceptability of an intervention to improve uptake and engagement with a mainstream weight management programme for people with SMI.

Methods
We worked with people with a lived-experience of SMI and used the person-based approach to develop the ‘Weight cHange for people with sErious mEntal iLlness’ (WHEEL) intervention. It comprised a referral to a mainstream weight management programme (WW®) to be attended once a week, in-person or online, for 12-weeks. The adjunct support comprised a one-off, online consultation called Meet Your Mentor and weekly, telephone or email Mentor Check Ins for 12-weeks. We assessed the feasibility of WHEEL through the number of programme and adjunct support sessions that the participants attended. We analysed the acceptability of WHEEL using a thematic analysis of qualitative interviews conducted at baseline and at 12-week follow-up. Our exploratory outcome of clinical effectiveness was self-reported weight at baseline and at end-of-programme.

Results
Twenty participants were assessed for eligibility and 17 enrolled. All 17 participants attended Meet Your Mentor and one was lost to follow-up (94% retention). Nine out of 16 attended ≥50% of the weekly programme sessions and 12/16 attended ≥50% of the weekly check-ins. Participants reported in the interviews that the adjunct support helped to establish and maintain a therapeutic alliance. While some participants valued the in-person sessions, others reported that they preferred the online sessions because it removed a fear of social situations, which was a barrier for some participants. The mean change in self-reported weight was − 4·1 kg (SD: 3·2) at 12-weeks.

Conclusions
A mainstream weight management programme augmented with brief and targeted education and low-intensity check-ins generated sufficient engagement and acceptability to warrant a future trial.
Young people’s explanations for the decline in youth drinking in England
Authors: Whitaker Victoria , Curtis Penny , Fairbrother Hannah , Oldham Melissa , Holmes John 
Published: March 2023

Abstract
Background
Youth alcohol consumption has fallen markedly over the last twenty years in England. This paper explores the drivers of the decline from the perspectives of young people.

Methods
The study used two methods in a convergent triangulation design. We undertook 38 individual or group qualitative interviews with 96 participants in various educational contexts in England. An online survey of 547 young people in England, was also conducted. Participants were aged between 12–19 years. For both data sources, participants were asked why they thought youth alcohol drinking might be in decline. Analysis of interview data was both deductive and inductive, guided by a thematic approach. Content analysis of survey responses further refined these themes and indicated their prevalence within a larger sample.

Results
The research identified eight key themes that young people used to explain the decline in youth drinking: The potential for alcohol-related harm; Contemporary youth cultures and places of socialisation; The affordability of alcohol; Displacement of alcohol by other substances; Access and the regulatory environment; Disputing the decline; Future Orientations; and Parenting and the home environment. Heterogeneity in the experiences and perspectives of different groups of young people was evident, particularly in relation to age, gender, and socio-economic position.

Conclusions
Young people’s explanations for the decline in youth drinking in England aligned well with those generated by researchers and commentators in prior literature. Our findings suggest that changing practices of socialisation, decreased alcohol affordability and changed attitudes toward risk and self-governance may be key explanations.
High variability of COVID-19 case fatality rate in Germany
Authors: Wjst Matthias , Wendtner Clemens 
Published: March 2023

Abstract
Background
During the first wave of the COVID-19 pandemic a high case fatality rate (CFR) was noticed worldwide including also Germany where the first European cases have been observed. The WHO recommended immediate intubation for patients with dyspnoea which has since been revised after reviewing the initial clinical outcome. The objective of this study is to analyze CFR and assess if there is an advantage of a more conservative management of COVID-19 induced hypoxemia.

Methods
PCR confirmed COVID-19 infections and death counts were obtained for all German districts from 27 Jan 2020 until 15 Feb 2021 using official reports of Robert Koch Institute Berlin, Germany. A moving average CFRt was constructed by dividing disease related deaths two weeks after a given index day by the number of infections two weeks prior to that date. In addition to a local comparison also mortality outcomes in other German speaking countries were compared.

Results
The mean CFR is estimated to be 2.92% based on 71.965 fatalities and 2.465.407 cases. There was a large regional scattering of CFRs across the German districts. Differences of the mortality pattern were observed also at state level and preserved across different sex and age groups while being largely independent of case numbers. Although Munich city had higher infection rates, more patients died during the first wave in Hamburg (OR 1.6, 95% CI 1.3–1.9) which was mirrored also by higher death risk at Hamburg intensive care units (OR 2.0, 95% CI 1.3–3.1). While the majority of Munich hospitals favoured a conservative management of hypoxemia including high flow nasal cannula (HFNC), Hamburg hospitals followed a more aggressive scheme of early mechanical ventilation (MV). Austria and Switzerland experienced higher CFRs than Germany during the first wave but after changing their treatment guidelines, both countries experienced lower CFRs during the second wave.

Conclusion
Using retrospective public health data, different case fatality rates have been observed across Germany. A more conservative management of COVID-19 induced Adult Respiratory Distress Syndrome (ARDS) is justified also by epidemiological data.

Authors: Ezzati Farahnaz , Mosadeghrad Ali Mohammad , Jaafaripooyan Ebrahim 
Published: March 2023

Abstract
Background
Health care facilities are responsible for preventing and controlling diseases and must be resilient enough to deal with crises. The Iranian health care facilities have faced challenges in managing COVID-19 pandemic. The purpose of this study was to identify the challenges faced by the Iranian health care facilities during the Covid-19 epidemic and to provide solutions.

Methods
This qualitative study was conducted with a phenomenological approach and using semi-structured interviews with 59 healthcare policy makers, managers, and employees, and medical university faculty members. The participants were selected through purposive and snowball sampling. Thematic analysis was used to analyze the data.

Results
Overall, 43 challenges to the resilience of health care facilities during the Covid-19 pandemic were identified and grouped into 8 themes (i.e., leadership and management, planning, organizational culture, organizational learning, employee management, customer management, resource management, and process management. The most important resilience challenges were: fragmented management system; poor leadership; incompatible health network structure; lack of a national holistic plan; poor case detection; insufficient resources; inefficient information system; negative attitude of managers and employee; organizational inertia; failure to build on lessons learned from crises; low workforce preparedness; lack of community-based management; and improper monitoring and evaluation. Managers should use community-based, evidence-based, and integrated management to build health system resilience against COVID-19, have sufficient knowledge and experience to organize operations, use appropriate and effective coordination models, develop a creative and participatory culture, reengineer processes, and provide necessary resources.

Conclusion
The Iranian health care facilities face challenges that prevent them from becoming resilient, responsive, and efficient in managing COVID-19. Policy makers and managers should increase the resilience of health care facilities to shocks and crises by using the suggested measures.
Inflammatory myofibroblastic tumour of the common bile duct: a case report and literature review
Authors: Huang Xiang , Li Guoli , Wang Jinjing , Zheng Hong 
Published: March 2023

Abstract
Introduction
Inflammatory myofibroblastic tumour (IMT) of the common bile duct (CBD) is an extremely rare low-grade malignancy with various biological behaviours and a lack of specific clinical and histopathological features. Preoperative and intraoperative diagnosis are challenging, and a diagnostic delay may increase surgical complexity.

Case presentation
We present the case of a 34-year-old male with no relevant medical history who presented with jaundice of 20 days of evolution. Histology and immunohistochemistry confirmed the diagnosis of an IMT with anaplastic lymphoma kinase (ALK)-1 expression. In addition, a review of the relevant literature revealed 13 published reports of biliary IMTs. The clinical history and histopathological features in these 13 cases were compared with those in our case to provide a comprehensive overview of the clinical manifestations and histopathological features of the disease.

Conclusion
IMT of the CBD is an extremely rare low-grade malignancy that mainly occurs in middle-aged female patients. The main clinical manifestation is monosymptomatic jaundice. The reported tumours originated in the middle and lower segments of the CBD, with an average size of approximately 3.5 cm × 3.0 cm and tumour cells expressing smooth muscle actin (SMA), vimentin and ALK. Abnormal ALK expression and ALK gene rearrangement represent potential histopathological and differential diagnoses. A clear diagnosis by preoperative biopsy and intraoperative frozen section examination is critical and can significantly reduce surgical trauma. The prognosis is good, and very few patients experience recurrence or distant metastasis.

Abstract
Background
Despite considerable efforts, ischemic stroke (IS) remains a challenging clinical problem. Therefore, the discovery of effective therapeutic and targeted drugs based on the underlying molecular mechanism is crucial for effective IS treatment.

Methods
A cDNA-encoding peptide was cloned from RNA extracted from Rana limnocharis skin, and the mature amino acid sequence was predicted and synthesized. Hemolysis and acute toxicity of the peptide were tested. Furthermore, its neuroprotective properties were evaluated using a middle cerebral artery occlusion/reperfusion (MCAO/R) model in rats and an oxygen–glucose deprivation/reperfusion (OGD/R) model in neuron-like PC12 cells. The underlying molecular mechanisms were explored using microRNA (miRNA) sequencing, quantitative real-time polymerase chain reaction, dual-luciferase reporter gene assay, and western blotting.

Results
A new peptide (NP1) with an amino acid sequence of ‘FLPAAICLVIKTC’ was identified. NP1 showed no obvious toxicities in vivo and in vitro and was able to cross the blood–brain barrier. Intraperitoneal administration of NP1 (10 nmol/kg) effectively reduced the volume of cerebral infarction and relieved neurological dysfunction in MCAO/R model rats. Moreover, NP1 significantly alleviated the decrease in viability and increase in apoptosis of neuron-like PC12 cells induced by OGD/R. NP1 effectively suppressed inflammation by reducing interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) levels in vitro and in vivo. Furthermore, NP1 up-regulated the expression of miR-6328, which, in turn, down-regulated kappa B kinase β (IKKβ). IKKβ reduced the phosphorylation of nuclear factor-kappa B p65 (NF-κB p65) and inhibitor of NF-κB (I-κB), thereby inhibiting activation of the NF-κB pathway.

Conclusions
The newly discovered non-toxic peptide NP1 (‘FLPAAICLVIKTC’) exerted neuroprotective effects on cerebral ischemia–reperfusion injury by reducing inflammation via the miR-6328/IKKβ/NF-κB axis. Our findings not only provide an exogenous peptide drug candidate and endogenous small nucleic acid drug candidate but also a new drug target for the treatment of IS. This study highlights the importance of peptides in the development of new drugs, elucidation of pathological mechanisms, and discovery of new drug targets.
Motor point heatmap of the calf
Authors: Schriwer Elias , Juthberg Robin , Flodin Johanna , Ackermann Paul W. 
Published: March 2023

Abstract
Background
Contractions of muscles in the calf induced by neuromuscular electrical stimulation (NMES) may prevent venous thromboembolism, help rehabilitation and optimize strength training, among other uses. However, compliance to NMES-treatment is limited by the use of suboptimal stimulation points which may cause discomfort and less effectivity. Knowledge of where one is most likely to find muscle motor points (MP) could improve NMES comfort and compliance.

Aims
To anatomically map the MPs of the calf as well as to calculate the probability of finding a MP in different areas of the calf.

Material and methods
On 30 healthy participants (mean age 37 years) anatomical landmarks on the lower limbs were defined. The location of the four most responsive MPs on respectively the medial and lateral head of gastrocnemius were determined in relation to these anatomical landmarks using a MP search pen and a pre-set MP search program with 3 Hz continuous stimulation (Search range:4.0–17.5 mA). The anatomy of the calves was normalized and subdivided into a matrix of 48 (6 × 8) smaller areas (3 × 3 cm), from upper medial to lower lateral, in order to calculate the probability of finding a MP in one of these areas. The probability of finding a MP was then calculated for each area and presented with a 95% confidence interval.

Results
The MP heatmap displayed a higher concentration of MPs proximally and centrally on the calf. However, there were wide inter-individual differences in the location of the MPs. The highest probability of finding a MP was in area 4, located centrally and medially, and in area 29, located centrolaterally and around the maximum circumference, both with 50% probability (95% CI: 0.31–0.69). The second highest probability of finding MPs was in areas 9, 10, 16, proximally and medially, all with 47% probability (95% CI: 0.28–0.66). These areas 4, 9, 10, 16 and 29 exhibited significantly higher probability of finding motor points than all areas with a mean probability of 27% and lower (p < 0.05) The lateral and distal outskirts exhibited almost zero probability of finding MPs.

Conclusions
This MP heatmap of the calf could be used to expedite electrode placement and to improve compliance in order to receive consistent and enhanced results of NMES treatments.
