Abstract
BACKGROUNDCOVID-19 has rapidly crossed borders, infecting people throughout the world. Women may be especially vulnerable to depression and anxiety due to the pandemic, AIMSThis study attempted to assess how gender impacts risk perceptions, anxiety levels behavioral responses to the COVID 19 pandemic in Pakistan in order to recommend gender responsive health policies METHODSA cross-sectional online survey was conducted. Participants were asked to complete a sociodemographic data form, the Hospital Anxiety and Depression Scale (HADS), and questions on their risk perceptions, preventive behavior and information exposure. Regression analysis was used to assess effects of factors such as age, gender and household income on anxiety levels.RESULTSOf the 1390 respondents, 478 were women, and 913 were men. Women considered their chances of survival to be relatively lower than men ( 59 % women vs 73% men). They were also more anxious (62% women vs 50% men), and more likely to adopt precautionary behavior, such as avoiding going to the hospital (78% women vs. 71% men), not going to work (72% women and 57% men), and using disinfectants (93% women and 86% men). Men were more likely to trust friends, family and social media as reliable sources of COVID-19 information, while women were more likely to trust doctors.CONCLUSIONWomen experience a disproportion burden of the psychological and social impact of the pandemic compared to men. Involving doctors in healthcare communication targeting women, might prove effective. Social media and radio programs may be effective in disseminating information related to COVID among men.

Published: November 2020

Abstract
PurposeChondral lesions of the lunate are one of the causes of ulnar-sided pain, but there has been little interest to date in treating them. In this paper, we describe a modification of the subchondral drilling technique in which an 18-gauge (G) needle was used as a sleeve to guide a K-wire to the lunate chondral defect.MethodsEleven patients (nine women, two men) who had undergone a simultaneous arthroscopic wafer procedure and lunate microfracture between 2014 and 2017 were retrospectively reviewed. After completion of the arthroscopic wafer procedure, an 18G needle was placed into the joint via the 6R portal and the needle tip was inserted into the subchondral bone. A 0.8-mm K-wire was then advanced through the needle and the lunate was drilled to a 2–3-mm depth. It is possible to safely drill remaining areas by only changing the direction of the needle. ResultsEight patients met inclusion criteria. There was no significant difference between the preoperative and postoperative wrist range of motion (p>0.05). Grip strength was significantly improved postoperatively (p<0.05). According to the Mayo wrist scoring system, six and one patients had excellent and good results, respectively.ConclusionArthroscopic lunate microfracture is an effective treatment for chondral defects of the lunate in the setting of ulnar impaction syndrome, and using a needle as a sleeve can ease manipulation and increase accuracy.

Abstract
Tendons enable movement by transferring muscle forces to the skeleton, and athletic performances critically rely on mechanically-optimized tendons. How load-bearing structures of tendon sense and adapt to physical demands is an open question of central importance to musculoskeletal medicine and human sports performance. Here, with calcium imaging in tendon explants and primary tendon cells we characterized how tenocytes detect mechanical forces and determined collagen fiber-sliding-induced shear stress as a key stimulus. CRISPR/Cas9 screening in human and rat tenocytes identified PIEZO1 as the crucial shear sensor. In rodents, elevated mechano-signaling increased tendon stiffness and strength both in vitro by pharmacological channel activation and in vivo by a Piezo1 gain-of-function mutation. Strikingly, humans carrying the PIEZO1 gain-of-function E756del mutation revealed a 16% average increase in normalized jumping height, with more effective storage of potential energy released during dynamic jumping maneuvers. We propose that PIEZO1-mediated mechano-signaling regulates tendon stiffness and impacts human athletic performance.

Abstract
Background A number of cases positive for SARS-CoV-2 escape surveillance systems, especially in the first epidemic waves and/or when the number of cases becomes too large to allow complete diagnostic coverage. Methods During the first SARS-CoV-2 epidemic wave hitting Italy in the spring 2020, mothers participating in an Italian NINFEA birth cohort were invited to complete an online questionnaire on COVID-19-like symptoms in the household. We estimated the population prevalence of COVID-19-like symptoms in children and adults, assessed their geographical correlation with the cumulative number of COVID-19 cases by province, analysed their clustering within families, and estimated their sensitivity, positive predictive value (PPV) and negative predictive value (NPV) for COVID-19 diagnosis in individuals tested for SARS-CoV-2.Results Information was collected on 3184 households, 6133 adults, and 5751 children. In the period March-April 2020, 55.4% of the NINFEA families had at least one member with at least one COVID-19-like symptom. There was a strong geographical correlation between the population cumulative incidence of COVID-19 and the prevalence of muscle pain, fatigue, low-grade fever, and breathing difficulties in adults (Spearman’s rho ≥0.70). Having at least one family member with a COVID-19 diagnosis, compared with none tested for SARS-CoV-2, was associated with an increased prevalence ratio (PR) of almost all COVID-19-like symptoms in adults, and only of low-grade fever (37-37.5°C; PR 5.27; 95% confidence intervals: 2.37 to 11.74) and anosmia/dysgeusia in children. Among adults with COVID-19 diagnosis, fatigue, muscle pain, and fever had a sensitivity ≥70%. In individuals tested for SARS-CoV-2, with a 16.6% prevalence of COVID-19, breathing difficulties and nausea/vomiting had the highest PPVs, with point estimates close to 60%, and with NPVs close to 90%.Conclusions The geographical prevalence of COVID-19-like symptoms in adults may inform on local disease clusters, while certain symptoms in family members of confirmed COVID-19 cases could help identify the intra-familial spread of the virus and its further propagation in the community. Low-grade fever is frequent in children with at least one household member with COVID-19 and possibly indicates child infection.

Abstract

Background: Despite the common restrictive abortion laws, abortion remains widespread in sub-Saharan Africa (SSA) countries. Women still utilize abortion services and put their lives and health at risk because abortion can only be procured illegally in private facilities such as mid-level or small patent medicine store that may be manned by unskilled providers or through a non-medicated approach. The objective of this study was to determine median years and factors of time to first abortion after sexual debut among Congolese women.Methods: We used data from the most recent Republic of Congo Demographic and Health Survey (DHS). A total sample of 3,622 women aged 15-49 years was analyzed. We estimated the overall prevalence of abortion and median years to first abortion. Furthermore, we examined the factors of time to first abortion after sexual debut using multivariable Cox regression and reported the estimates using adjusted Hazard Ratio (aHR) and 95% confidence intervals (CI). Statistical significance was determined at p<0.05.Results: The prevalence of abortion was 60.0% and median years of time to first abortion after sexual debut was 9.0. The prominent reasons for abortion were due to too short birth interval (23.8%), lack of money (21.0%) and that husband/partner did not need a child at that time (14.0%). Women’s age and region were notable factors in timing to first abortion. Furthermore, women from poorer, middle, richer and richest households had 34%, 67%, 86% and 94% higher risk of abortion respectively, when compared with women from poorest households (aHR estimates). Women currently in union/living with a man and formerly in union had 41% and 29% reduction in the risk of abortion respectively, when compared with those never in union (aHR estimates). In addition, women with primary and secondary+ education had 42% and 76% higher risk of abortion respectively, when compared with women with no formal education (aHR estimates).Conclusion: There was high prevalence of abortion with short years at first abortion. Abortion was associated with women’s characteristics. There is need for unwanted pregnancy prevention intervention and the improvement in pregnancy care to reduce adverse pregnancy outcomes among women.

Abstract
Roll-bond cladded plates Have found extensive industrial applications. Stainless steels, Ni, Cu, and Ti have been usually employed as clad. In multi-piece head manufacturing, delamination may occur during pressing these plates into petals. In this paper, the effective parameters on delamination were investigated. SA 516 GR 70 and SS 316L were respectively selected as the base plate and clad due to their higher applications. First, the strain energy release rate (SERR) was assessed as the main criterion for the definition of delamination and the explanatory parameter using the finite element technique and virtual crack closure technique (VCCT) method. The interface was modeled as a cohesive zone with the tied mesh technique and validated by the experimental results. The response surface methodology (RSM) was employed as a design of experiment method to evaluate the effect of input parameters on the outputs (SERR). The results indicated the greater influence of the head radius on G followed by the thickness of the plate, pressing force, the number of pressing steps, shear strength, and friction coefficient. By enhancing the radius of the head and shear strength, SERR was decreased. The impact of the head radius was much greater than that of shear strength. Finally, some strategies have been proposed to prevent delamination.

Published: November 2020

The problem of choosing an infusion solution, especially in starting therapy, for various critical conditions, remains debatable, especially in children with specifics of water-electrolyte metabolism, which determines their tendency to imbalance of water and electrolytes.
Objectives. Comparative evaluation of the succinate-containing solution and the malate-containing solution as a starting infusion therapy in the early postoperative period in children.
Materials and methods. A randomized prospective study in 40 patients with an ASA II–III score who underwent an operation. In the first group “R” 20 children receive succinate-containing solution and in the second group “S” 20 children receive malate-containing solution. At the study stages inter- and intra- group differences were estimated by the dynamics of the water-electrolyte and acid-base conditions, phase angle values — the calculated integral indicator of the state of the membranes of cell structures, and basal metabolism.
Results. No significant differences between groups at all stages of the study were obtained. However, in group “S” there was a dynamic, statistically significant by 180 minutes after the start of fluid administration, a decrease in the phase angle by 4.1 %, despite the fact that in group “R” the deviations were not significant.
Conclusion. There were no statistically significant differences between the solutions used as starting infusion therapy drugs in the early postoperative period in the indicated modes, and they can be used equally well. However, the noted statistically significant changes in the phase angle in the group with malate-containing solution indicated a tendency to it is negative effect on the state of cell structures, which, apparently, should be taken into account with more significant volumes and duration of fluid administration.

Authors: Ataka Takuya , Kimura Noriyuki , Mizukami Takeshi , Uchida Hirotatsu , Matsubara Etsuro 
Published: November 2020

Background:
Adiponectin has been implicated in the pathophysiology of dementia, especially
Alzheimer’s disease. However, the association between cerebrospinal fluid (CSF) adiponectin
levels and positron emission tomography (PET) imaging remains unclear.

Objective:
To explore whether CSF adiponectin levels are associated with 11C-Pittsburgh compound
B (PiB) or 18F-fluorodeoxyglucose (FDG) uptake in amnestic mild cognitive impairment (MCI) subjects.

Methods:
Thirty-four amnestic MCI subjects underwent PiB-PET, FDG-PET, and CSF analysis.
The CSF adiponectin levels were measured using the Bio-Plex 200 suspension array system. PET
uptake was assessed for the frontal and temporoparietal lobes and posterior cingulate gyrus, referenced
against the cerebellar cortex. The increased brain amyloid burden was defined as a mean
uptake value ratio greater than 1.4. Spearman’s rank correlation analysis and a multiple regression
model were used to examine the association between CSF adiponectin levels and PiB or FDG
uptake.

Results:
The mean age was 76.3 years; 38.2% were men, and 61.8% were women. A high amyloid
burden was identified in 18 (52.9%) subjects. CSF adiponectin levels positively correlated with
global FDG uptake (β = 0.45; 95% confidence interval (CI), 0.13 to 0.76, p < 0.01), especially in the
parietotemporal lobe and posterior cingulate gyrus (β = 0.70; 95% CI, 0.41 to 0.99, p<0.01,
β = 0.33; 95% CI, 0.03 to 0.63, p = 0.03, respectively) after adjusting for covariates, including age,
sex, education years, body mass index, vascular risk factors, ApoEε4 status, and PiB status in all
amnestic MCI subjects.

Conclusion:
CSF adiponectin levels were associated with cortical glucose metabolism, particularly
in the specific regions that connect with the medial temporal, but not brain amyloid burden in amnestic
MCI subjects.

Social Skill in Kaulinan Huhuian: The Story from Indonesia
Authors: Maulani Susan 
Published: November 2020

The notion about social skill often was ignored in elementary school because many teachers thought that students’ learning achievement was more important than skill development. This study tried to describe conceptually about social skill in kaulinan huhuian. The research method was case study. Six teachers of Elementary School from two different schools in Bandung City, West Java, Indonesia were selected as participant. Data was collected through semi structure interview and observation. Data analysis process by using grounding approach. The finding of this study showed that there were some social activities in kaulinan huhuian, namely deciding who become ucing, making formation like hui (sweet potatoes), sing kakawihan (song), and dialog between ucing and huiand. Social skill that can be developed was honesty, togetherness and the ability to interact with other people and the surrounding environment. This finding also can give solution to generate learning process whether model, strategy, technique which develop social skill in students.
