Post-operative ovarian morphology upon sonography after ovarian torsion-Effect regarding quick surgical treatment: A new retrospective cohort research.
There is widespread acknowledgement that coronavirus disease 2019 (COVID-19) has disrupted surgical services. The European Society of Thoracic Surgeons (ESTS) sent out a survey to assess what impact the COVID-19 pandemic has had on the practice of thoracic oncology surgery.

All ESTS members were invited (13-20 April 2020) to complete an online questionnaire of 26 questions, designed by the ESTS learning affairs committee.

The response rate was 23.0% and the completeness rate was 91.2%. The number of treated COVID-positive cases per hospital varied from fewer than 20 cases (30.6%) to more than 200 cases (22.7%) per hospital. Most hospitals (89.1%) postponed surgical procedures. All hospitals performed patient screening with a nasopharyngeal swab, but only 6.7% routinely tested health care workers. A total of 20% of respondents reported that multidisciplinary meetings were completely cancelled and 66%, that multidisciplinary decisions were not different from normal practice. Trends were recognized in prioritizing surgical patients based on age (younger than 70), type of surgery (lobectomy or less), size of tumour (T1-2) and lymph node involvement (N1). Sixty-three percent of respondents reported that surgeons were involved in daily care of COVID-19-positive patients. Fifty-three percent mentioned that full personal protective equipment was available to them when treating a COVID-19-positive patient.

The COVID-19 pandemic has created issues for the safety of health care workers, and surgeons have been forced to change their routine practice. However, there was no consensus about surgical priorities in lung cancer patients, demonstrating the need for the production of specific guidelines.

These tiny molecules can regulate target genes (mRNAs) through either cleavage or translational inhibition. Recently, the discovery of plant-derived miRNAs showing cross-kingdom abilities to regulate mammalian gene expression has prompted exciting discussions among researchers. After being acquired orally through the diet, plant miRNAs can survive in the digestive tract, enter the circulatory system, and regulate endogenous mRNAs. Here, we review current knowledge regarding the cross-kingdom mechanisms of plant miRNAs, related controversies, and potential applications of these miRNAs in dietary therapy, which will provide new insights for plant miRNA investigations related to health issues in humans.
Are GnRH tests and serum inhibin B levels sufficiently discriminating to distinguish transient constitutional delay of growth and puberty (CDGP) from congenital hypogonadotropic hypogonadism (CHH) that affects reproductive health for life?

Both parameters lack the specificity to discriminate CDGP from CHH.

GnRH tests and inhibin B levels have been proposed to differentiate CDGP from CHH. However, their diagnostic accuracies have been hampered by the small numbers of CHH included and enrichment of CHH patients with more severe forms.

The aim of this study was to assess the diagnostic performance of GnRH tests and inhibin B measurements in a large cohort of CHH male patients with the whole reproductive spectrum. From 2008 to 2018, 232 males were assessed 127 with CHH, 74 with CDGP and 31 healthy controls.

The participants were enrolled in two French academic referral centres. The following measurements were taken testicular volume (TV), serum testosterone, inhibin B, LH and FSH, both at baseline and friminate CHH from CDGP. This reflects the varying degree of gonadotropin deficiency inherent to CHH. These two diagnostic procedures may misdiagnose partial forms of isolated (non-syndromic) CHH, allowing them to be erroneously considered as CDGP.

There are no competing interests.

However, this notion raises a fundamental question as to how these classic androgens pass through the placenta without being converted by aromatase into oestrogens. Here, we report a case of maternal adrenal tumour, in which overproduction of 11-oxygenated C19 steroids (11ox C19s), newly characterised non-aromatisable androgens in humans, caused foetal virilisation. The female proband presented with severely virilised external genitalia at birth. The mother exhibited hirsutism, hyperglycaemia and hypertension and was diagnosed as having adrenal tumour. The mother was subjected to comprehensive steroid measurement. Serum levels of 11ox C19s were markedly elevated. In contrast, testosterone and androstenedione levels remained within the normal range, and levels of most other steroids in the conventional and backdoor androgenic pathways were normal or only mildly elevated. After tumour removal, levels of 11ox C19s were markedly reduced. These results provide the first evidence that 11ox C19s can be synthesised in adrenal adenomas and, due to their non-aromatisable nature, can pass through the placental barrier to cause foetal virilisation. These findings highlight a unique pathogenic property of these newly specified androgens in humans.
To assess the impact of ESBL production on mortality and length of hospital stay (LOS) of community-onset infections due to Escherichia coli or Klebsiella pneumoniae.

A population-based cohort study including all adult patients hospitalized with a first-time community-onset E. coli or K. check details pneumoniae bacteraemia or urinary tract infection in the North Denmark Region between 2007 and 2017. For each bacterial agent, we computed 1 year Kaplan-Meier survival curves and cumulative incidence functions of LOS, and by use of Cox proportional hazard regression we computed HRs as estimates of 30 day and 1 year mortality rate ratios (MRRs) and LOS among patients with and without ESBL-producing infections.

We included 24 518 cases (among 22350 unique patients), of whom 1018 (4.2%) were infected by an ESBL-producing bacterium. The 30 day cumulative mortality and adjusted MRR (aMRR) in patients with and without ESBL-producing isolates was as follows E. coli bacteraemia (n = 3831), 15.8% versus 14.0%, aMRR = 1.01 (95% CI = 0.
