in the associated algorithm. (Figure 1) CONCLUSION The presence of male infertility is crucial to the health of patients and its effects must be considered for the welfare of society. This document will undergo updating as the knowledge regarding current treatments and future treatment options continues to expand.

The summary presented herein represents Part II of the two-part series dedicated to the Diagnosis and Treatment of Infertility in Men AUA/ASRM Guideline. Part II outlines the appropriate management of the male in an infertile couple. Medical therapies, surgical techniques, as well as use of intrauterine insemination (IUI)/invitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) are covered to allow for optimal patient management. Please refer to Part I for discussion on evaluation of the infertile male and discussion of relevant health conditions that are associated with male infertility.

The Emergency Care Research Institute Evidence-based Practice Center team searched PubMed®, Embase®, and Medline from January 2000 through May 2019. SCR7 inhibitor When sufficient evidence existed, the body of evidence was assigned a strength rating of A (high), B (moderate), or C (low) for support of Strong, Moderate, or Conditional Recommendations. In the absence of sufficient evidence, additional information is provided ay. This document will undergo additional literature reviews and updating as the knowledge regarding current treatments and future treatment options continues to expand.

Graft rejection after intestinal transplantation remains challenging. We aimed to use endoscopy for rejection prediction.

Patients ≥7 years old who underwent intestinal transplantation between November 2016 and September 2019 were prospectively enrolled. Magnifying endoscopy under narrow-band imaging was performed through ileostomy. Endoscopic findings were reported as five components (each graded from 0-2) "V" (villi appearance), "E" (erythema), "N" (capillary network), "C" (crypt widening), and "H" (heterogeneity). The correlation between histological severity and endoscopic score was analyzed.

Ninety-nine endoscopic biopsies from three female and one male patient were analyzed. The mean ± SD age was of 41.25±13.77 (range 29-58) years. Three short bowel syndrome patients after multiple intestinal resections and one with chronic intestinal pseudo-obstruction were indicated for intestinal transplantation. Sensitivity, specificity, and accuracy of V, E, N, C, and H scores for predicting rejection were 97.4%, 45.9%, 65.7%; 94.7%, 70.5%, 79.8%; 97.4%, 52.5%, 69.7%; 94.7%, 54.1%, 69.7%; and 97.4%, 62.3%, 75.8%, respectively. Pearson's correlation coefficients between total and individual V, E, N, C, H scores and histological rejection were 0.79, 0.64, 0.70, 0.71, 0.73, and 0.66, respectively (P < .001). To predict mild and moderate/severe rejection, total scores more than 4 and 6 had the sensitivity/specificity of 87.50%/57.38% and 96.67%/85.25%, respectively (area under the ROC 0.791 and 0.987).

Endoscopic VENCH scoring is promising for predicting rejection after IT. More studies are warranted to validate such results. (ClinicalTrials.gov number, NCT03616548.).

Approximately 10% of people with cystic fibrosis (CF) have mutations that result in little to no CFTR production and thus cannot benefit from CFTR modulators. We previously found that Amphotericin B (AmB), a small molecule that forms anion channels, restored HCO



secretion and increased host defenses in primary cultures of CF airway epithelia. Further, AmB increased ASL pH inCFTR-null pigs, suggesting an alternative CFTR-independent approach to achieve gain-of-function. However, it remains unclear whether this approach can be effective in people.

To determine whether AmB can impact physiology in people with CF, we first tested whether Fungizone, a clinically approved AmB formulation, could cause electrophysiological effects consistent with anion secretion in primary cultures of CF airway epithelia. We then evaluated the capacity of AmB to change nasal potential difference (NPD), a key clinical biomarker, in people with CF not on CFTR modulators.

AmB increased transepithelial Cl

current and hyperpolarized calculated transepithelial voltage in primary cultures of CF airway epithelia from people with two nonsense mutations. In eight people with CF not on CFTR modulators, intranasal Fungizone treatment caused a statistically significant change in NPD. This change was similar in direction and magnitude to the effect of ivacaftor in people with a G551D mutation.

Our results provide the first evidence that AmB can impact a clinical biomarker in people with CF. These results encourage additional clinical studies in people with CF to determine whether small molecule anion channels can provide benefit.

The presence of co-morbidities, including underlying respiratory problems, has been identified as a risk factor for severe COVID-19 disease. Information on the clinical course of SARS-CoV-2 infection in children with cystic fibrosis (CF) is limited, yet vital to provide accurate advice for children with CF, their families, caregivers and clinical teams.

Cases of SARS-CoV-2 infection in children with CF aged less than 18 years were collated by the CF Registry Global Harmonization Group across 13 countries between 1 February and 7 August 2020.

Data on 105 children were collated and analysed. Median age of cases was ten years (interquartile range 6-15), 54% were male and median percentage predicted forced expiratory volume in one second was 94% (interquartile range 79-104). The majority (71%) of children were managed in the community during their COVID-19 illness. Out of 24 children admitted to hospital, six required supplementary oxygen and two non-invasive ventilation. Around half were prescribed antibiotics, five children received antiviral treatments, four azithromycin and one additional corticosteroids.
