Associations between COVID-19 therapies and inpatient gastrointestinal bleeding: A multisite retrospective study.

Little data is available regarding the incidence of gastrointestinal bleeding in adults hospitalized with COVID-19 infection and the influence of patient comorbidities and demographics, COVID-19 therapies, and typical medications used. In this retrospective study, we utilized the National COVID Cohort Collaborative to investigate the primary outcome of the development of gastrointestinal bleeding in 512 467 hospitalized US adults (age \u3e18 years) within 14 days of a COVID-19 infection and the influence of demographics, comorbidities, and selected medications. Gastrointestinal bleeding developed in 0.44% of patients hospitalized with COVID-19. Comorbidities associated with gastrointestinal bleeding include peptic ulcer disease (adjusted odds ratio [aOR] 10.2), obesity (aOR 1.27), chronic kidney disease (aOR 1.20), and tobacco use disorder (aOR 1.28). Lower risk of gastrointestinal bleeding was seen among women (aOR 0.76), Latinx (aOR 0.85), and vaccinated patients (aOR 0.74). Dexamethasone alone or with remdesivir was associated with lower risk of gastrointestinal bleeding (aOR 0.69 and aOR 0.83, respectively). Remdesivir monotherapy was associated with upper gastrointestinal bleeding (aOR 1.25). Proton pump inhibitors were more often prescribed in patients with gastrointestinal bleeding, likely representing treatment for gastrointestinal bleeding rather than a risk factor for its development. In adult patients hospitalized with COVID-19, the use of dexamethasone alone or in combination with remdesivir is negatively associated with gastrointestinal bleeding. Remdesivir monotherapy is associated with increased risk of upper gastrointestinal bleeding

Distal hypospadias repair in infants without a postoperative stent.

PURPOSE: To review our experience with infants undergoing distal hypospadias repair without a postoperative stent to determine if an unacceptable complication rate might justify its use. METHODS: ChildrenDemographics, meatus position, operative technique and complications were also recorded. Patients older than 1 year or with hypospadias proximal to a subcoronal position were excluded. RESULTS: Eighty-nine patients without a stent were identified in addition to 21 patients who had a stent for a minimum of 3 days. At 3 months follow-up, 4/89 (4.49 %) patients in the stentless group required circumcision revision. 1 patient experienced urinary retention. 1/21 (4.76 %) patients with a postoperative stent required reoperation for meatal stenosis. CONCLUSIONS: The complication rate for infants undergoing distal hypospadias repair is low, does not appear to be significantly increased by forgoing a postoperative urethral stent. Avoiding a stent likely reduces a variety of associated adverse events and needs for short-term follow-up

Infected joint replacements in HIV-positive patients with haemophilia

Joint replacement in HIV-positive patients remains uncommon, with most experience gained in patients with haemophilia. We analysed retrospectively the outcome of 102 replacement arthroplasties in 73 HIV-positive patients from eight specialist haemophilia centres. Of these, 91 were primary procedures. The mean age of the patients at surgery was 39 years, and the median follow-up was for five years. The overall rate of deep sepsis was 18.7% for primary procedures and 36.3% for revisions. This is a much higher rate of infection than that seen in normal populations. A total of 44% of infections resolved fully after medical and/or surgical treatment. The benefits of arthroplasty in haemophilic patients are well established but the rates of complications are high. As this large study has demonstrated, high rates of infection occur, but survivorship analysis strongly suggests that most patients already diagnosed with HIV infection at the time of surgery should derive many years of symptomatic relief after a successful joint replacement. Careful counselling and education of both patients and healthcare workers before operation are therefore essentia

Clean intermittent catheterization as an initial management strategy provides for adequate preservation of renal function in newborns with persistent cloaca.

INTRODUCTION: Persistent cloaca is a rare, congenital anomaly involving the genital, urinary, and rectal organ systems. While prompt bowel diversion is the standard of care, the optimal method of genitourinary decompression is unclear. Bladder outlet obstruction and hydrometrocolpos are common complications that can lead to obstructive uropathy, abdominal distention, infection, perforation, and acidosis. Proposed management strategies include early surgical diversion (vesicostomy, vaginostomy, ureterostomy, nephrostomy) or clean intermittent catheterization (CIC) of the common channel. We hypothesized that CIC is an adequate means of genitourinary decompression and preservation of renal function, regardless of the severity of cloacal anomaly. METHODS: We reviewed all patients with persistent cloaca from a single, tertiary care center from 1995 to 2013. We collected data regarding renal function (serial serum creatinine prior to definitive reconstruction, and baseline estimated glomerular filtration rate [GFR]), presence of hydrocolpos, hydronephrosis, vesicoureteral reflux (VUR) or renal dysplasia, and length of the common channel. A linear mixed model was used to calculate creatinine change over time in relation to method of management and child age. Estimated GFR was calculated using the Schwartz equation for neonates = 0.45 × height in cm/serum creatinine in mg/dL. The t test was used for continuous data and Fisher\u27s exact test was used for binomial data. A p value RESULTS: Twenty-five patients were identified. Nine (36%) patients underwent early surgical diversion versus 16 (64%) managed by CIC prior to formal reconstruction. Seven had short common channels (\u3c3 \u3ecm) and 18 had long common channels (≥3 cm). Hydrocolpos was present in 14 (56%) of the patients. When comparing the two management groups, there was no significant difference in hydronephrosis, high-grade hydronephrosis (grades III-IV, p = 0.62), any VUR (p = 0.33), high-grade VUR (grades III-V, p = 0.62), hydrocolpos (p = 0.21), or renal dysplasia (p = 0.42). No significant differences were found between mean baseline GFR for diversion (22.9 mL/min per 1.73 m(2)) versus CIC (39.2 mL/min per 1.73 m(2), p = 0.22). There was no difference in creatinine trend between the two groups. DISCUSSION: Currently, there is no consensus on the initial management of obstructive uropathy and resulting hydrocolpos in newborns with persistent cloaca. In addition to CIC, management strategies include surgical options such as vesicostomy, vaginostomy, or upper tract diversions such as ureterostomy or nephrostomy. Our results suggest that CIC is similar to these other proposed diversion procedures while minimizing morbidity. Creatinine trends over time were similar between the two groups and reached comparable nadirs. Limitations of our study include the retrospective nature of a small sample size. The primary risk is differences between the two groups that we were not able to appreciate. Furthermore, we did not attempt to assess the morbidity of the two different strategies. CONCLUSIONS: CIC is an adequate initial management strategy to decompress the genitourinary tract in patients with persistent cloaca. CIC preserves renal function similar to early surgical decompression
