Intracytoplasmic sperm injection (ICSI) is commonly used to solve male infertility problems. Previous studies showed that early environmental exposure of an embryo may influence postnatal development. To detect whether ICSI operations affect the reproductive health of a male or his offspring, we established assisted reproductive technologies (ART) conceived mouse models, and analyzed gene expression profiles in the testes of both ICSI and naturally conceived (NC) newborn F1 mice using micro-array analysis. Among the differentially expressed genes, we focused on the expression of eight male reproduction-related genes. Quantitative real-time reverse transcription-polymerase chain reaction (qRT-PCR) was used to analyze the expression of these genes in the testes of both adult and old F1 generation mice and adult F2 generation mice. Our results showed that down-regulated and somatic cell-expressed genes in newborn mice retained their differential expression patterns in adult and old F1 generation individuals, implying the persistence and fetal origin of the alteration in the expression of these genes. The intergenerational transmission of differential gene expression was observed, but most changes tended to be reduced in adult F2 generations. Controlled ovarian hyperstimulation (COH) and in vitro fertilization (IVF) mice models were added to explore the precise factors contributing to the differences in ICSI offspring. The data demonstrated that superovulation, in vitro culture, and mechanical stimulation involved in ICSI had a cumulative effect on the differential expression of these male reproductive genes.

Objectives: To investigate the rate of, and factors affecting, acceptance of pharmacists' recommendations by medical prescribers following medication reviews conducted in non-hospitalized older adults.
Design: A systematic review and meta-analysis with meta-regression.
Setting And Participants: Older adults (mean age ≥55 years) residing in the community or in aged care facilities (ie, non-hospitalized) who had received an individualized medication review by a pharmacist.

Background & Aims: Pancreatic cysts often pose challenges in predicting malignant progression. Next-generation sequencing has become an appealing ancillary diagnostic test. The diagnostic performance is well characterized, but the impact on clinical management remains unclear.

Syndromic primary hyperparathyroidism has several features in common: younger age at diagnosis when compared with sporadic primary hyperparathyroidism, often synchronous or metachronous multi-glandular involvement, higher possibility of recurrence, association with other endocrine or extra-endocrine disorders, and suggestive family background with autosomal dominant inheritance. Hyperparathyroidism in multiple endocrine neoplasia type 1 is the most common syndromic hyperparathyroidism. It is often asymptomatic in adolescents and young adults, but may be responsible for recurrent lithiasis and/or bone loss.

Background Context: There are a number of risk factors- from biological, psychological, and social domains- for non-specific chronic low back pain (cLBP). Many cLBP treatments target risk factors on the assumption that the targeted factor is not just associated with cLBP but is also a cause (i.e, a causal risk factor).

Background: PATHFINDER was a prospective cohort study of multicancer early detection (MCED) testing in an outpatient ambulatory population. The aim of this study is to report the patient-reported outcomes (PROs) collected as secondary and exploratory measures in the PATHFINDER study.
Methods: PATHFINDER is a prospective, multicentre, cohort study that enrolled existing healthy ambulatory outpatients at seven health networks in the USA, including hospitals, academic medical centres, and integrated health systems.
