Protocol for the development of a core outcome set for studies on centralisation of healthcare services.Centralisation defined as the reorganisation of healthcare services into fewer specialised units serving a higher volume of patients is a potential measure for healthcare reforms aiming at reducing costs while improving quality. Research on centralisation of healthcare services is thus essential to inform decision-makers. However, so far studies on centralisation report a variability of outcomes, often neglecting outcomes at the health system level. Therefore, this study aims at developing a core outcome set (COS) for studies on centralisation of hospital procedures, which is intended for use in observational as well as in experimental studies.

Massive generalised lymphadenopathy: a rare presentation of tuberculosis with a favourable outcome.We present a case of massive generalised necrotic lymphadenopathy due to tuberculosis (TB) without any solid organ involvement. An immunocompetent man in his early 30s presented 1 year ago with weight loss, cough and a solitary cervical node. Contrast-enhanced CT scan thorax showed massive enlargement of almost all groups of mediastinal nodes with large areas of necrosis. Ultrasound examination revealed multiple necrotic abdominal nodes. Core biopsy of the supraclavicular node confirmed TB by histopathology and molecular testing. His Mantoux test was negative suggesting tuberculin anergy. Biopsy of deep nodes was avoided. He responded well to standard antitubercular treatment in weight-corrected doses along with systemic steroids which were prescribed to prevent further breakdown/rupture of nodes. After the extended TB treatment for 12 months, he is asymptomatic and has gained weight, with complete resolution of cervical node and near complete resolution of all deep nodes.

Filopodia-like protrusions of adjacent somatic cells shape the developmental potential of oocytes.The oocyte must grow and mature before fertilization, thanks to a close dialogue with the somatic cells that surround it. Part of this communication is through filopodia-like protrusions, called transzonal projections (TZPs), sent by the somatic cells to the oocyte membrane. To investigate the contribution of TZPs to oocyte quality, we impaired their structure by generating a full knockout mouse of the TZP structural component myosin-X (MYO10). Using spinning disk and super-resolution microscopy combined with a machine-learning approach to phenotype oocyte morphology, we show that the lack of decreases TZP density during oocyte growth. Reduction in TZPs does not prevent oocyte growth but impairs oocyte-matrix integrity. Importantly, we reveal by transcriptomic analysis that gene expression is altered in TZP-deprived oocytes and that oocyte maturation and subsequent early embryonic development are partially affected, effectively reducing mouse fertility. We propose that TZPs play a role in the structural integrity of the germline-somatic complex, which is essential for regulating gene expression in the oocyte and thus its developmental potential.
