Background: People with head and neck cancer have higher comorbidity levels but it remains unclear if pretreatment comorbidity is an independent prognosticator in head and neck cancer.
Methods: Survival analyses were performed using data from participants in a UK multicentre cohort study with cancers of the oral cavity (n = 668), oropharynx (n = 1074), and larynx (n = 530). Survival analyses were incrementally adjusted for age, sex, marital status, income, education, stage, alcohol, and smoking.
Results: After adjusting for demographic, clinical, and behavioral confounders, higher baseline comorbidity was associated with reduced overall survival (mild comorbidity HR = 1.4, 95% CI = 1.1, 1.7; moderate comorbidity HR = 1.7, 95% CI = 1.3, 2.2; severe comorbidity HR = 2.8, 95% CI = 1.9, 4.; P-trend<.001).
Conclusions: Our findings suggest that comorbidity is an independent prognosticator for overall survival in head and neck cancer. Comorbid illnesses should be considered in the assessment and treatment planning of people with head and neck cancer.

German Cancer Consortium (DKTK), partner site Tübingen, and German Cancer Research Center (DKFZ), Heidelberg, Germany.
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).
Lesbian, gay, bisexual, and transgender clinical competence of health professionals in Poland and Spain: results of the health exclusion research in Europe (HERE) study.

Group of Research in Care and Health (GRUPAC), Faculty of Health Sciences, University of La Rioja, Logroño, 26006, Spain.
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.
BMC Musculoskelet Disord
January 2025
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.
Silent witnesses: unveiling the epidemic of femicides in North-west Tshwane, South Africa - a decade of analysis.

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.
