HAART and anti-Koch’s impair sexual competence,sperm quality and offspring quality when used singly and in combination in male Wistar rats

This study investigated the impact of the administration of HAART and anti-Koch's, singly and in combination, on sexual competence and birth statistics. Adult male Wistar rats were randomised into distilled water-treated control, HAART-treated, anti-Koch's-treated and HAART + anti-Koch's-treated groups. The 56-day oral treatment led to impaired sexual competence evident by significantly reduced motivation to mate, prolonged latencies of mount, intromissions, ejaculations and post-ejaculatory interval, as well as reduced frequencies of mount, intromissions and ejaculations. This was accompanied by significant reductions in penile erection reflex and penile grooming. HAART and anti-Koch's, when administered singly or in combination, also led to significant reductions in the circulatory follicle-stimulating hormone, luteinizing hormone, testosterone and intratesticular testosterone, but a significant rise in prolactin. Also, HAART and/or anti-Koch's significantly reduced sperm count, sperm motility, sperm viability and spermatozoa with normal morphology. Furthermore, HAART and anti-Koch's, separately or in combination, significantly lowered fertility capacity, litter size and litter weight and offspring survival. The deleterious effects of these drugs were more pronounced when combined. Findings of the present study revealed that HAART and/or anti-Koch's impair sexual competence via a testosterone-dependent hyperprolactinemia-mediated mechanism. These events are associated with reduced fertility capacity, poor sperm quality and lowered offspring survival.     

The implementation of an infection control bundle within a Total Care Burns Unit

AimTo evaluate the impact of the implementation of a best practice infection prevention and control bundle on healthcare associated burn wound infections in a paediatric burns unit.BackgroundBurn patients are vulnerable to infection. For this patient population, infection is associated with increased morbidity and mortality, thereby representing a significant challenge for burns clinicians who care for them.MethodsAn interrupted time series was used to compare healthcare associated burn wound infections in paediatric burn patients before and after implementation of an infection prevention and control bundle. Prospective surveillance of healthcare associated burn wound infections was conducted from 2012 to 2014. Other potential healthcare associated infection rates were also reviewed over the study period, including urinary tract infections, pneumonia, upper respiratory tract infections and sepsis. An infection prevention and control bundle developed in collaboration between the paediatric burn unit and infection control clinicians was implemented in 2013 in addition to previous standard practice.ResultsDuring the study period a total of 626 patients were admitted to the paediatric burns unit. Healthcare associated burn wound infections reduced from 34 in 2012 to 0 in 2014 following the implementation of the infection prevention and control bundle. Pneumonia and sepsis also reduced to 0 in 2013 and 2014, however one upper respiratory tract infection occurred in 2013 and urinary tract infections persisted in 2013.ConclusionThe implementation of an infection prevention and control bundle was effective in reducing healthcare associated burn wound infections, pneumonia and sepsis within our paediatric burns unit. Urinary tract infections remain a challenge for future improvement.

Health-related quality of life,uncertainty and coping strategies in solid organ transplant recipients during shielding for the COVID-19 pandemic

Strict isolation of vulnerable individuals has been a strategy implemented by authorities to protect people from COVID-19. Our objective was to investigate health-related quality of life (HRQoL), uncertainty and coping behaviours in solid organ transplant (SOT) recipients during the COVID-19 pandemic. A cross-sectional survey of adult SOT recipients undergoing follow-up at our institution was performed. Perceived health status, uncertainty and coping strategies were assessed using the EQ-5D-5L, Short-form Mishel Uncertainty in Illness Scale (SF-MUIS) and Brief Cope, respectively. Interactions with COVID-19 risk perception, access to health care, demographic and clinical variables were assessed. The survey was completed by 826 of 3839 (21.5%) invited participants. Overall, low levels of uncertainty in illness were reported, and acceptance was the major coping strategy (92%). Coping by acceptance, feeling protected, self-perceived susceptibility to COVID-19 were associated with lower levels of uncertainty. Health status index scores were significantly lower for those with mental health illness, compromised access to health care, a perceived high risk of severe COVID-19 infection and higher levels of uncertainty. A history of mental health illness, risk perceptions, restricted healthcare access, uncertainty and coping strategies was associated with poorer HRQoL in SOT recipients during strict isolation. These findings may allow identification of strategies to improve HRQoL in SOT recipients during the pandemic.     

Comparison of benign and malignant insulinoma

BackgroundHow malignant insulinomas present relative to benign insulinomas is unknown.MethodsA single-institution retrospective study identified patients with insulinoma. Malignancy was defined by distant metastases, positive lymph node(s), T stage of 4, direct invasion into surrounding peripancreatic tissue, or presence of lymphovascular invasion. Wilcoxon Rank Sum tests and Kaplan-Meier analysis were used.ResultsA total of 311 patients were identified: 51 malignant and 260 benign. Patients with malignant insulinoma presented with higher levels of insulin, proinsulin, and c-peptide. Malignant lesions were larger: 4.2 ± 3.2 vs 1.8 ± 0.8 cm in benign lesions, p < 0.01. Overall survival at 5 years was 66.8% vs 95.4% for malignant and benign insulinoma respectively, p < 0.01.ConclusionsLarger size of insulinoma and increased serum β-cell polypeptide concentrations were associated with malignancy. Malignant insulinoma has poorer survival. Further work-up to rule out malignancy may be indicated for larger pancreatic lesions and for patients with higher pre-operative insulin and pro-insulin.     

Is same-day discharge associated with increased 30-day postoperative complications and readmissions in patients undergoing laparoscopic adrenalectomy?

BackgroundAdvances in minimally invasive surgery and perioperative care have decreased substantially the duration of time that patients spend recovering in hospital, with many laparoscopic procedures now being performed on an ambulatory basis. There are limited studies, however, on same-day discharge after laparoscopic adrenalectomy. The objectives of this study were to investigate the outcomes and trends of ambulatory laparoscopic adrenalectomy in a multicenter cohort of patients.MethodsAdult patients who underwent elective laparoscopic adrenalectomy between 2005 and 2016 were identified in the database of the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP). Baseline demographics and 30-day outcomes were compared between patients who underwent ambulatory laparoscopic adrenalectomy and those who were discharged after an inpatient stay. Multivariable logistic regression and Cox proportional hazards modelling were used to investigate the association between same-day discharge and 30-day complications and unplanned readmissions.ResultsOf the 4,807 patients included in the study, 88 (1.8%) underwent ambulatory laparoscopic adrenalectomy and 4,719 (98.2%) were admitted after the adrenalectomy. The same-day discharge group contained fewer obese patients (37.2% vs 50%; P = .04), a lesser proportion of American Society of Anesthesiologists class III patients (45.5% vs 61%; P = .003), and more patients with primary aldosteronism (14.8% vs 6%; P = .002) compared with the inpatient group. After adjustment for confounders, same-day discharge was not associated with 30-day overall complications (OR 1.17, 95% CI 0.35–3.85; P = .80) or unplanned readmissions (HR 2.77, 95% CI 0.86–8.96; P = .09). The percentage of laparoscopic adrenalectomies performed on an ambulatory basis at hospitals participating in the ACS NSQIP remained low throughout the study period (0–3.1% per year) with no evidence of an increasing trend over time (P = .21).ConclusionAmbulatory laparoscopic adrenalectomy is a safe and feasible alternative to inpatient hospitalization in selected patients. Further study is needed to determine the cost savings, barriers to uptake, and optimal selection criteria for this approach.     

Optimizing the fellowship interview process: Perspectives from applicants and program directors of the comprehensive endocrine surgery fellowship program

BackgroundApproximately 80% of general surgery residents undertake some form of fellowship training. Our objective was to characterize goals and burdens of the interview process among applicants to Comprehensive Endocrine Surgery Fellowship programs.MethodsParticipants included trainees from 2013 to 2019. Results for ranking questions are presented as a mean rank reported out of the total number of selections.ResultsResponse rate was 54% (n = 75). The most important goal for interviews was meeting the faculty (mean rank 2.4/9), followed by “behind the scenes information” and “make a good impression” (mean rank 3.6 and 3.7, respectively). The most substantial burden for the applicant was expense (mean rank 2.1/7), followed by time away from residency (mean rank 3.1/7). The economic burden of 51% of the applicants was $2,500 to $7,500. Geographic location and expense were the top 2 reasons applicants declined offers of interviews. Despite the process, 76% of respondents indicated that no improvements to the interview process are necessary. Alternative strategies such as videoconferencing or centralized interviews received little support (<10%).ConclusionDespite identifying several burdens, survey respondents believed that in-person interviews are an integral component of the fellowship application process. Indeed, 70% of applicants do not have a first-choice program before interviews, and meeting the faculty is ranked as the greatest priority goal. Our data illustrate the importance of individual specialties evaluating and optimizing their own processes for fellowship interviews.
