Prognosis of Cirrhotic Patients After Osteoporotic Femoral Neck Fracture.

: Osteoporotic hip fractures in cirrhotic subjects are associated with increased post-fracture mortality. Our aim was to identify unfavorable factors that were associated with increased post-fracture mortality. : We employed a retrospective evaluation of the short- and long-term prognosis of cirrhotic patients that were admitted with a hip fracture to our institution.

Clinical Practice Guidelines in an Era of Accountability, Saudi Arabia: A Call for Action.

Introduction: Clinical Practice Guidelines (CPGs) development and implementation in the Kingdom of Saudi Arabia are suboptimal. The Kingdom's Vision 2030 envisages a transformational change to achieve an effective, integrated, value-based ecosystem focused on patient health.

Objectives: This study aimed to develop a CPG appraisal tool that will support the realization of the Kingdom's Vision 2030 through the development of high-quality and highly implementable CPGs.

The effect of physical and social isolation due to the COVID-19 pandemic on the incidence of hip fractures among senior citizens.

This study aimed to explore the effects of the lockdown due to the coronavirus disease 2019 pandemic on the incidence and characteristics of hip fracture in older adults. Data from the three-month lockdown period and the corresponding period in the previous year were obtained from the computerized medical records of a large acute-care hospital. No significant differences were observed in the absolute and relative numbers of hip fractures.

Identification of new minimally lost regions on 18q in head and neck squamous cell carcinoma.

Loss of heterozygosity (LOH) on 18q predicts poor survival in head and neck squamous cell carcinomas (HNSCCs). Several putative tumor suppressor genes, such as DCC, DPC4/Smad4, and MADR2/Smad2, are mapped to 18q, but thus far, the important gene locus in HNSCC is not known. To identify possible gene loci on 18q, we performed LOH studies using tumor DNA from 57 HNSCC primary tumor cell lines and DNA isolated from fibroblasts or lymphoblastoid cells from the same patients.

Defining regions of the Y-chromosome responsible for male infertility and identification of a fourth AZF region (AZFd) by Y-chromosome microdeletion detection.

Cytogenetic and molecular deletion analyses of azoospermic and oligozoospermic males have suggested the existence of AZoospermia Factor(s) (AZF) residing in deletion intervals 5 and 6 of the human Y-chromosome and coinciding with three functional regions associated with spermatogenic failure. Nonpolymorphic microdeletions in AZF are associated with a broad spectrum of testicular phenotypes. Unfortunately, Sequence Tagged Sites (STSs) employed in screening protocols range broadly in number and mapsite and may be polymorphic.
