Abstract
Background
Thrombotic thrombocytopenic purpura (TTP) considers a rare cause of ischemic stroke (IS). We reported a case of a newly diagnosed patient with acquired immune-mediated TTP (iTTP), in whom two IS events developed during 48 h.

Case presentation
A 59-year-old diabetic male was presented to the hospital 24 h after symptoms onset, including left hemiparesis, dysarthria, and decreased consciousness. A brain CT scan was performed with the suspicion of acute IS, indicating infarct lesions in the right middle cerebral artery (MCA) territory. The patient was not eligible for thrombolytic therapy due to admission delay. Over the next 24 h, the patient’s neurological condition deteriorated, and the second brain CT scan showed new ischemic lesions in the left MCA territory. Initial laboratory evaluation indicated thrombocytopenia without evidence of anemia. However, in the following days, thrombocytopenia progressed, and microangiopathic hemolytic anemia (MAHA) developed. The ADAMTS-13 (a disintegrin and metalloproteinase with a thrombospondin type 1 motif, member 13) activity and inhibitors assay confirmed the diagnosis of iTTP. The patient underwent plasma exchange activity and inhibitors assay confirmed the diagnosis of iTTP. The patient underwent and pulse IV methylprednisolone. Rituximab was also added due to the refractory course of the disease. After a prolonged hospital course, he had considerable neurologic recovery and was discharged.

Conclusions
Clinicians should consider two points. First, TTP should be considered in any patient presenting with IS and having thrombocytopenia or anemia without other symptoms of TTP. Second, worsening the patient's condition during hospitalization may indicate a new stroke and should be investigated immediately.

Abstract
Background
With the impact of over two centuries of colonisation in Australia, First Nations families experience a disproportionate burden of adverse pregnancy and birthing outcomes. First Nations mothers are 3–5 times more likely than other mothers to experience maternal mortality; babies are 2–3 times more likely to be born preterm, low birth weight or not to survive their first year. ‘Birthing on Country’ incorporates a multiplicity of interpretations but conveys a resumption of maternity services in First Nations Communities with Community governance for the best start to life. Redesigned services offer women and families integrated, holistic care, including carer continuity from primary through tertiary services; services coordination and quality care including safe and supportive spaces. The overall aim of Building On Our Strengths (BOOSt) is to facilitate and assess Birthing on Country expansion into two settings - urban and rural; with scale-up to include First Nations-operated birth centres. This study will build on our team’s earlier work - a Birthing on Country service established and evaluated in an urban setting, that reported significant perinatal (and organisational) benefits, including a 37% reduction in preterm births, among other improvements.

Methods
Using community-based, participatory action research, we will collaborate to develop, implement and evaluate new Birthing on Country care models. We will conduct a mixed-methods, prospective birth cohort study in two settings, comparing outcomes for women having First Nations babies with historical controls. Our analysis of feasibility, acceptability, clinical and cultural safety, effectiveness and cost, will use data including (i) women’s experiences collected through longitudinal surveys (three timepoints) and yarning interviews; (ii) clinical records; (iii) staff and stakeholder views and experiences; (iv) field notes and meeting minutes; and (v) costs data. The study includes a process, impact and outcome evaluation of this complex health services innovation.

Discussion
Birthing on Country applies First Nations governance and cultural safety strategies to support optimum maternal, infant, and family health and wellbeing. Women’s experiences, perinatal outcomes, costs and other operational implications will be reported for Communities, service providers, policy advisors, and for future scale-up.

Pre-operative anemia and peri-operative transfusion are associated with poor oncologic outcomes in cancers of the esophagus: potential impact of patient blood management on cancer outcomes
Authors: Connor Joseph P. , Destrampe Eric , Robbins Daniel , Hess Aaron S. , McCarthy Daniel , Maloney James 
Published: January 2023

AbstractBackgroundBoth Red Blood Cell (RBC) transfusion and anemia are thought to negatively impact cancer survival. These effects have been reported with mixed findings in cancer of the esophagus. The potential impact of the application of restrictive transfusion strategies on this patient population has not been defined.Materials and MethodsWe conducted a retrospective study of esophagectomies and studied cases based on whether they were anemic or were transfused peri-operatively. Clinical characteristics and known clinicopathologic prognosticators were compared between these groups. Survival was compared by Cox proportional hazard modeling. Post-operative transfusions were assessed for compliance with restrictive transfusion thresholds.ResultsThree-hundred ninety-nine esophagectomy cases were reviewed and after exclusions 348 cases were analyzed. The median length of follow-up was 33 months (range 1–152 months). Sixty-four percent of patients were anemic pre-operatively and 22% were transfused. Transfusion and anemia were closely related to each other. Microcytic anemia was uncommon but was evaluated and treated in only 50% of cases. Most anemic patients had normocytic RBC parameters. Transfusion but not anemia was associated with a protracted/prolonged post-operative stay. Transfusion and anemia were both associated with reduced survival however only anemia was associated with decreased survival in multi-variable modeling. Sixty-eight percent of patients were transfused post-operatively and 11% were compliant with the restrictive threshold of 7 g/dL.ConclusionsPre-operative anemia and transfusion are closely associated, however only anemia was found to compromise survival in our esophageal cancer cohort, supporting the need for more aggressive evaluation and treatment of anemia. Adherence to restrictive transfusion guidelines offers an opportunity to reduce transfusion rates which may also improve short-term outcomes.
Does self-perceived HIV risk mediate the potential association between HIV-related symbolic stigma and sexual behaviour among young adult women in Cape Town, South Africa?
Authors: Machemedze Takwanisa 
Published: January 2023

Abstract
Background
Perception of risk is a central construct of models of health behaviour change as it is assumed to be an intermediate step before adoption of the related safer behaviour. In the context of HIV/AIDS, the literature suggests that psychosocial factors such as stigmatising attitudes related to stereotyping people who contract HIV may influence how people perceive their own risk of HIV infection. However, findings on the relationships between HIV-related stigma, HIV risk perception and sexual behaviour have been inconsistent. We investigated the potential mediating role of HIV risk perception on the link between HIV-related symbolic stigma and sexual behaviour.

Methods
Data used in this study are a sub-sample of 384 young adult women, aged 17–25 years, who participated in the Cape Area Panel Study conducted in Cape Town, South Africa. Study participants were asked questions relating to their demographic details, their social and economic situation, and sexual and reproductive health behaviour. The outcome measure was a composite measure of sexual behaviour derived from whether the young adult women ever had sex before, previous number of sexual partners and condom use. The mediator variable was self-perceived risk of contracting HIV. The independent variable was HIV-related symbolic stigma attitudes. Mediation analysis within the structural equation modeling (SEM) framework was used to examine if participants who held elevated stigma attitudes perceived their risk of HIV infection to be low and as a result ended up engaging in unsafe sex.

Results
Higher HIV-related symbolic stigma attitudes were associated with perception of reduced risk of contracting HIV (β = -0.248, p = 0.008, 95% CI = [-0.431, -0.066]) and perception of higher risk of contracting HIV was significantly associated with unsafe sex practices (β = 0.179, p = 0.038, 95% CI = [0.010, 0.348]). The indirect path was not significant (β = -0.044, p = 0.084, 95% CI = [-0.095, 0.006]), suggesting no mediation relationship.

Conclusions
Stigmatising attitudes towards groups of people stereotyped as at risk of HIV infection was associated with perception of invulnerability to HIV, and the question on how this relationship affects risk sexual behaviour needs further investigation.

AbstractObjectivesThe Central Dry Zone (CDZ) is one of the most important livestock production areas of Myanmar. However, there is an eminent lack of information on the attitudes and traditional beliefs of local farmers and livestock supply chain actors in CDZ of Myanmar on the public health implications. A modified data collection instrument of the Health Belief model was developed to investigate attitudes, beliefs and barriers to the application of recommended zoonotic disease prevention.Study designCross-sectional study.MethodData analyses were conducted considering a two-phase multilevel mixed effect binomial generalized linear models modelling approach.ResultsThe availability of information about zoonosis to supply chain actors influenced their confidence to implement preventive actions (OR = 1.5,p = 0.045 for cattle diseases; OR = 1.5,p = 0.022 for village chicken diseases). Supply chain actors were more likely aware of zoonosis transmitted by cattle compared to livestock farmers (OR = 0.3,p = 0.005 for cattle farmers), while people not rearing or trading small ruminants and/or poultry were less likely to be aware of the zoonotic risk associated with these animals (p < 0.005). Information on zoonosis transmitted from small ruminants was mainly promoted through farmers (p = 0.032), while information on zoonotic diseases that can be obtained from chickens was disseminated through farmers, local authorities and the media. Nevertheless, appropriate hand hygiene measures (i.e. cleaning of hands after touching, cutting, cooking meat) (OR = 7.7,p < 0.001 for zoonotic small ruminant diseases; OR = 1.6,p = 0.073 for zoonotic village chicken diseases) and treating of sick animals (OR = 7.3,p < 0.001 for small ruminant zoonotic diseases; OR = 2.2,p = 0.031 for village chicken zoonotic diseases) increased the confidence of small ruminant and village chicken owners to prevent these zoonotic infections.ConclusionsThe findings from this study indicate that while gender and the availability of information on zoonotic risks play an important role on the perceived threat of zoonoses, the practice of prevention methods influenced the confidence of value chain actors (VCAs) on zoonoses prevention.
Sexual and reproductive health of CDC plantation camp residents: a focus on unmet need for family planning among women in union
Authors: Emeh Agbor Nathan , Hermann Ngouakam , Tanue Elvis Asangbeng , Dickson Nsagha Shey 
Published: January 2023

Abstract
Background
Sexual and reproductive health is crucial to a normal and healthy female life. However, little interest has been placed on this subject particularly in the resource-limited settings of Cameroon. The study assessed the sexual and reproductive health of women in union, resident in the Cameroon Development Corporation (CDC) plantation camps, Cameroon.

Methods
This was a cross-sectional study carried out from December 2019 to February 2020 in which a multi-stage sampling was applied in two purposively selected CDC plantation camps (Tiko and Penda Mboko). Out of the 16 clusters making up the camps, 8 were randomly selected using simple balloting. The main street junctions of the sampled clusters were identified and a direction of sampling randomly chosen. All houses left to the data collectors were sampled for eligible participants (one participant per household) and data were collected using validated interviewer-administered questionnaires. The number of participants per cluster was proportionate to population size of cluster. Data was analysed using SPSS 16 and statistical significance was set at p < 0.05. Regression analysis was used to determine predictors of unmet need for family planning.

Results
Out of the 414 participants included, primary education was the highest level of education for a majority (43.0%). Most of the participants (44.7%) earned between 44.5–89.0USD/month. Relatively high proportions of some sexual and reproductive indicators like early sexual contacts (before 15 years) [87(21.0%)], grand multiparity [41(9.9%)], and abortion ≥ 3 [8(1.9%)] were recorded in the study. Two hundred and seventy-eight (278) participants (67.1%) [95%CI:62.4–71.7] used contraceptives and 90 (21.7%) [95%CI:17.9–26.0] had an unmet need for family planning with 3 major reasons for non-use of contraception among them being fear of side effects, discouragement from the partner, and lack of sufficient information on contraception. Of the different predictors of unmet need for family planning assessed, nulliparity/primiparity were protective for unmet need, and this was statistically significant (AOR = 0.284[0.086–0.934]).

Conclusion
The sexual and reproductive health of CDC plantation camp residents is poor, and a health intervention is needed to improve it.

Abstract
Introduction
Handgrip strength (HGS) measures the maximum voluntary force of the hand, which has been used to assess individual health status indirectly. Although several factors related to HGS have been identified, studies among adults in Malaysia are lacking. This study aimed to provide the normative reference HGS values and determine its predictor factors among healthy adults of Malay ethnic in Malaysia.

Methodology
This study was a part of the Prospective Urban Rural Epidemiology (PURE) study carried out among adults aged between 35 to 70 years old residing in urban and rural Malaysian communities. A standardised questionnaire was used to assess the socio-demographic information and physical activity level of respondents who provided written informed consent to participate in this study. HGS was measured using Jamar’s dynamometer. A total of 3,446 healthy adults of Malay ethnic were included in this study. Descriptive data were used to derive the normative reference values for HGS using means and standard deviations stratified by age and gender. The predictors of HGS were determined using a general linear model (GLM).

Results
Mean HGS ranged from 38.48 (± 9.40) kg for the dominant hand of men aged 35–40 years to 16.53 (± 5.69) kg for the non-dominant hand of women aged 61–70 years. The ANOVA indicated that there was a significant descending trend of HGS as age increased for both genders (p < 0.05). The ANOVA also revealed that participants working in blue- or white-collar jobs had higher HGS than their counterparts who are homemakers (p < 0.05). The GLM shows that, age, occupation type, socio-economic status (SES), physical activity level and BMI significantly predicted dominant HGS among male and meanwhile, only age, SES and BMI significantly predicted dominant HGS among female.

Conclusion
HGS normative values provided herein can serve as a guide for interpreting HGS measurements obtained from healthy Asian adults especially Malay ethnic. The clinicians and researcher can use the established HGS reference values as comparison in their patients or participants. Furthermore, during a rehabilitation process, the clinicians and researchers could use the normal score ranges to document the progress of HGS and provide feedback to the patients. Further study with prospective study design is needed to determine the causal effect association of the predictors and HGS.
Risk factor analysis and a new prediction model of venous thromboembolism after pancreaticoduodenectomy
Authors: Yin Zhi-Jie , Huang Ying-Jie , Chen Qi-Long 
Published: January 2023

Abstract
Aim
The present study aimed to identify risk factors for venous thromboembolism (VTE) after pancreaticoduodenectomy (PD) and to develop and internally validate a predictive model for the risk of venous thrombosis.

Methods
We retrospectively collected data from 352 patients who visited our hospital to undergo PD from January 2018 to March 2022. The number of patients recruited was divided in an 8:2 ratio by using the random split method, with 80% of the patients serving as the training set and 20% as the validation set. The least absolute shrinkage and selection operator (Lasso) regression model was used to optimize feature selection for the VTE risk model. Multivariate logistic regression analysis was used to construct a prediction model by incorporating the features selected in the Lasso model. C-index, receiver operating characteristic curve, calibration plot, and decision curve were used to assess the accuracy of the model, to calibrate the model, and to determine the clinical usefulness of the model. Finally, we evaluated the prediction model for internal validation.

Results
The predictors included in the prediction nomogram were sex, age, gastrointestinal symptoms, hypertension, diabetes, operative method, intraoperative bleeding, blood transfusion, neutrophil count, prothrombin time (PT), activated partial thromboplastin time (APTT), aspartate aminotransferase (AST)/alanine aminotransferase (ALT) ratio (AST/ALT), and total bilirubin (TBIL). The model showed good discrimination with a C-index of 0.827, had good consistency based on the calibration curve, and had an area under the ROC curve value of 0.822 (P < 0.001, 95%confidence interval:0.761–0.882). A high C-index value of 0.894 was reached in internal validation. Decision curve analysis showed that the VTE nomogram was clinically useful when intervention was decided at the VTE possibility threshold of 10%.

Conclusion
The novel model developed in this study is highly targeted and enables personalized assessment of VTE occurrence in patients who undergo PD. The predictors are easily accessible and facilitate the assessment of patients by clinical practitioners.

AbstractBladder cancer, one of the most prevalent malignant cancers, has high rate of recurrence and metastasis. Owing to genomic instability and high-level heterogeneity of bladder cancer, chemotherapy and immunotherapy drugs sensitivity and lack of prognostic markers, the prognosis of bladder cancer is unclear. Necroptosis is a programmed modality of necrotic cell death in a caspase-independent form. Despite the fact that necroptosis plays a critical role in tumor growth, cancer metastasis, and cancer patient prognosis, necroptosis-related gene sets have rarely been studied in bladder cancer. As a result, the development of new necroptosis-related prognostic indicators for bladder cancer patients is critical. Herein, we assessed the necroptosis landscape of bladder cancer patients from The Cancer Genome Atlas database and classified them into two unique necroptosis-related patterns, using the consensus clustering. Then, using five prognosis-related genes, we constructed a prognostic model (risk score), which contained 5 genes (ANXA1, DOK7, FKBP10, MAP1B and SPOCD1). And a nomogram model was also developed to offer the clinic with a more useful prognostic indicator. We found that risk score was significantly associated with clinicopathological characteristics, TIME, and tumor mutation burden in patients with bladder cancer. Moreover, risk score was a valid guide for immunotherapy, chemotherapy, and targeted drugs. In our study, DOK7 was chosen to further verify our prognosis model, and functional assays indicated that knockdown the expression of DOK7 could prompt bladder cancer proliferation and migration. Our work demonstrated the potential role of prognostic model based on necroptosis genes in the prognosis, immune landscape and response efficacy of immunotherapy of bladder cancer.
