Objectives: To evaluate treatment compliance to weekly concurrent chemoradiotherapy (CRT) in head and neck squamous cell carcinoma (HNSCC).
Study Design: Retrospective analysis.
Setting: Tertiary care hospital.
Main Outcome Measures: Overall treatment time (OTT), acute radiation morbidity and treatment completion rate without prolongation of overall treatment time of more than 2 days.
Results: Three hundred and seventy-eight head and neck carcinoma patients treated with radical CRT with 70 Gy/35 fractions of radiotherapy with weekly cisplatin 40 mg/m(2) were included in the study. Median age was 52 years (range 22-77 years), oropharynx was most commonly (54%) involved site, and 55% were in stage IV disease. Majority (86%) of patients were able to complete cancer-directed therapy, median OTT was 52 days (46-140 days). Nineteen per cent of patients completed treatment without prolongation of OTT beyond 2 days and 68% of patients there completed treatment prolongation of OTT beyond 7 days. Nearly, sixty-six of the patients experienced grade II or higher acute radiation morbidities.
Conclusions: Delivery of weekly low-dose concurrent CRT is safe and feasible. Two-thirds of the patients experienced treatment prolongation of more than 2 days and 14% could not complete treatment. Results within in the study suggest to a greater need to lay emphasis on continuity of a course of radical CRT for HNSCC.

Background: For radiotherapy of head and neck cancer (HNC) magnetic resonance imaging (MRI) plays a pivotal role due to its high soft tissue contrast. Moreover, it offers the potential to acquire functional information through diffusion weighted imaging (DWI) with the potential to personalize treatment. The aim of this study was to acquire repetitive DWI during the course of online adaptive radiotherapy on an 1.

Background: The endoplasmic reticulum stress (ER stress) has been involved in various musculoskeletal disorders including non-traumatic osteonecrosis of femoral head (NT-ONFH).
Objective: The current study aimed to investigate the association of glucose-regulated protein 78 (GRP78) as well as CCAAT/enhancer-binding protein homologous protein (CHOP) expressions in serum and femoral head (FH) tissues with NT-ONFH's severity.
Methods: We enrolled NT-ONFH patients (n = 150) alongside healthy controls (HCs, n = 150).

Introduction: Health disparities experienced by lesbian, gay, bisexual, and transgender (LGBT) individuals have been partially attributed to healthcare professionals' lack of cultural competence in addressing their specific needs. This study aimed to assess the differences in competencies and preparedness among health professionals from Poland and Spain when working with LGBT patients.
Methodology: Data were collected between June and August 2024 through a cross-sectional survey involving 673 health professionals (Mage = 33.
The effects of the positioning of a bolt in the femoral neck system on the short-term outcomes of middle-aged and young adults with displaced femoral neck fractures.

Department of Orthopedics, The Affiliated Suzhou Hospital of Nanjing Medical University, Suzhou Municipal Hospital, Gusu School, Nanjing Medical University, Suzhou, 215000, China.
Background: To analyze the effects of the positioning of a bolt in the femoral neck system (FNS) on the short-term outcomes of middle-aged and young adults with displaced femoral neck fractures (FNFs).
Methods: This was a retrospective study involving 114 middle-aged and young adults with displaced FNFs who were surgically treated with internal fixation via the FNS in the Department of Orthopedics, Suzhou Municipal Hospital, from December 2019 to January 2023. The degree of deviation of the central axis of the femoral head and neck from the tip of the bolt (W), the tip‒apex distance (TAD) and the length of femoral neck shortening (LFNS) were measured on postoperative X-ray and computed tomography (CT) scan images.

Sefako Makgatho University, Ground Floor, Clin Path Building, Room No. 37. Garankuwa, Pretoria, South Africa.
Background: Femicides, defined as the gender-based killing of women, are a pressing public health issue worldwide, with South Africa experiencing some of the highest rates globally. This study focuses on the North-west region of Tshwane, particularly the Garankuwa area, aiming to address gaps in understanding the epidemiology, demographics, circumstances, and pathology associated with femicides. The Garankuwa mortuary serves as the primary site for this investigation, providing a detailed analysis over a ten-year period, shedding light on contributing risk factors in the context of systemic gender inequality.
