What happens when you stop using the combined contraceptive pill? A qualitative study protocol on consequences and supply needs for women who discontinued the combined contraceptive pill in Germany.

BMJ Open 2022 Jun 27;12(6):e057089. Epub 2022 Jun 27.

Institute of Medical Sociology, Martin Luther University Halle Wittenberg, Halle, Sachsen-Anhalt, Germany.

Introduction: For more than 60 years, contraceptive pills have been prescribed to mostly healthy biological women. An emerging body of research concerning the possible physiological and psychological side effects of hormonal contraception has been published over the past two decades. Consequently, discontinuing combined oral contraceptives (COCs) as a conscious decision for reasons other than desired pregnancy has become increasingly common for menstruating individuals.

Development and validation of a tool for advising primiparous women during early labour: study protocol for the GebStart Study.

BMJ Open 2022 Jun 27;12(6):e062869. Epub 2022 Jun 27.

Research Institute of Midwifery, Zurich University of Applied Sciences, Winterthur, Switzerland.

Introduction: Pregnant women experience early labour with different physical and emotional symptoms. Early admission to hospital has been found to be associated with increased intervention and caesarean section rates. However, primiparous women often contact the hospital before labour progresses because they encounter difficulties coping with symptoms of onset of labour on their own. Read More

Efferent Activity Controls Hair Cell Response to Mechanical Overstimulation.

eNeuro 2022 Jun 27. Epub 2022 Jun 27.

Department of Physics and Astronomy, UCLA, Los Angeles, CA 90095

The efferent pathway strengthens the auditory system for optimal performance by fine-tuning the response and protecting the inner ear from noise-induced damage. Although it has been well-documented that efference helps defend against hair cell and synaptic extinction, the mechanisms of its otoprotective role have still not been established. Specifically, the effect of efference on an individual hair cell's recovery from mechanical overstimulation has not been demonstrated. Read More

Non-ischaemic cardiomyopathy associated with elevated serum cobalt and accelerated wear of a metal-on-metal hip resurfacing.

BMJ Case Rep 2022 Jun 27;15(6). Epub 2022 Jun 27.

Orthopaedic Surgery, Henry Ford Health System, Detroit, Michigan, USA.

A man in his late 30s developed non-ischaemic cardiomyopathy due to systemic cobalt toxicity associated with accelerated bearing surface wear from metal-on-metal hip resurfacing implanted in the previous 6 years. Following revision arthroplasty, the patient regained baseline cardiac function. Cobalt-induced cardiomyopathy is a grave condition that deserves early consideration due to potentially irreversible morbidity. Read More

Metastatic renal cell cancer and first-line combinations: for which patients? (focus on tolerance and health-related quality of life).

Bull Cancer 2022 May;109(2S):2S19-2S30

CHU Besançon, Oncologie, F-25030 Besançon cedex, France; INSERM, UMR1098, F-25020 Besançon cedex, France; Université de Franche-Comté, UBFC, F-25020 Besançon, France. Electronic address:

Until recently, the first-line treatments used in metastatic renal cell carcinoma were based on first-generation anti-VEGFR (vascular endothelial growth factor receptor) tyrosine kinase inhibitors (TKIs) as monotherapy. Trials combining immunotherapy (IO) (anti-CTLA4 + anti-PD-1) or immunotherapy with TKIs showed striking results in the first-line setting with improvement in overall response rates, progression-free survival and overall survival versus sunitinib. This allowed the combinations to gain registration in the US and Europe in the first-line advanced or metastatic clear-cell renal cell carcinoma setting. Read More

'What puts the 'Hic' into Hiccups?'

BMJ Open Gastroenterol 2022 Jun;9(1)

Digestive Function: Basel, Laboratory and Clinic for Motility Disorders and Functional Digestive Diseases, Klinik Arlesheim AG, Arlesheim, BS, Switzerland

Recurrent and persistent bouts of hiccups impact the quality of life by interfering with eating, social interaction and work. Popular home remedies, such as breath holding and drinking ice water, target activity in the vagal and phrenic nerves that are thought to trigger these repetitive, myoclonic contractions. However, the pathophysiology of hiccups and the mechanism by which any of these methods work are unclear. Read More

Authorship representation in global emergency medicine: a bibliometric analysis from 2016 to 2020.

BMJ Glob Health 2022 Jun;7(6)

Division of Pediatric Emergency Medicine, Emory University School of Medicine, Atlanta, Georgia, USA.

Introduction: High-income country (HIC) authors are disproportionately represented in authorship bylines compared with those affiliated with low and middle-income countries (LMICs) in global health research. An assessment of authorship representation in the global emergency medicine (GEM) literature is lacking but may inform equitable academic collaborations in this relatively new field.

Methods: We conducted a bibliometric analysis of original research articles reporting studies conducted in LMICs from the annual GEM Literature Review from 2016 to 2020. Read More

Acta Biomater 2022 Jun 24. Epub 2022 Jun 24.

Department of Mechanical Engineering, and Iowa Technology Institute The University of Iowa, Iowa City, IA 52242, USA. Electronic address:

We propose a new approach for constructing strain-based rupture criterion for ascending thoracic aortic aneurysm. The rupture metric is formulated using an effective strain, which is a measure of net strain that the collagen bundles experience after fiber uncrimping. The effective strain is a function of the total strain and the waviness properties of the collagen fibers. Read More

Challenges and opportunities in the use of transcriptomics characterization for human iPSC-derived BBB models.

Toxicol In Vitro 2022 Jun 24:105424. Epub 2022 Jun 24.

University of Artois, UR 2465, Laboratoire de la Barrière Hémato-Encéphalique (LBHE), Faculté des sciences Jean Perrin, Rue Jean Souvraz SP18, F-62300 Lens, France. Electronic address:

The blood-brain barrier (BBB) is localized at the brain microvascular endothelial cells. These cells form a tight barrier, limiting the access of cells, pathogens, chemicals, and toxins to the brain due to tight junctions and efflux transporters. As the BBB plays a role in the assessment of neurotoxicity and brain uptake of drugs, human in vitro BBB models are highly needed. Read More
