The Efficacy and Safety of a Conservative Management Approach to Radiation-Induced Male Urethral Strictures in Elderly Patients With Comorbidities

Objectives To assess the outcomes of a conservative management approach to radiation-induced urethral stricture disease (R-USD) in an elderly population with comorbidities. Methods Patients with R-USD managed with endoscopic procedures and/or clean intermittent catheterization (CIC) between 2007 and 2019 were included. Patients were excluded if they had an obliterative stricture, prior urethral reconstruction/urinary diversion surgery, or < 3 months follow-up. Primary outcome measures were urinary tract infection (UTI), acute urinary retention (AUR), serum creatinine, uroflowmetry/post-void residual, and urinary incontinence (UI). Failure was defined as progression to reconstructive surgery or permanent indwelling catheterization. Results Ninety-one men were analyzed with a median follow-up of 15.0 months (IQR 8.9 to 37.9). Median age was 75.4 years (IQR 70.0 to 80.0), body mass index was 26.5 kg/m2 (IQR 24.8 to 30.3), and Charlson comorbidity index was 6 (IQR 5 to 8). Median stricture length was 2.0 cm (IQR 2.0 to 3.0). Stricture location was bulbar (12%), bulbomembranous (75%), and prostatic (13%). A total of 90% underwent dilation, and 44% underwent direct visual internal urethrotomy (DVIU). For those that underwent these procedures, median number of dilations and DVIUs per patient was 2 (IQR 1 to 5) and 1 (IQR 1 to 3), respectively. Forty percent used CIC. Thirty-four percent developed a UTI, and 15% had an AUR episode requiring urgent treatment. Creatinine values, uroflowmetry measurements, and UI rates remained stable. Eighty percent avoided reconstructive surgery or indwelling catheterization. Conclusion Most elderly patients with comorbidities with R-USD appear to be effectively managed in the short-term with conservative strategies. Close observation is warranted because of the risk of UTIs and AUR. The potential long-term consequences of repetitive conservative interventions must be considered.

Comparison of Short-Term Results of Laparoscopy and Open Surgery for Colorectal Cancer: A Single-Center Experience

Objective: Although laparoscopic colon cancer surgeries have increased in recent years, their oncological competence is questioned. In our study, we aimed to evaluate oncological competence by comparing laparoscopic and open surgery. Material and Methods: The study was planned retrospectively. A total of 94 patients were included in the study, 42 of whom underwent laparoscopy, and 52 patients underwent open surgery. Both groups were compared in terms of demographic characteristics, staging, number of benign/malignant lymph nodes, histological findings and complications. Result: The final pathology report of all patients was adenocarcinoma. The median number of dissected lymph nodes was 20.9 in the open group (8-34) and 19.46 in the laparoscopy group (7-31) (p=0.639). The median number of dissected malignant lymph nodes was 1 (0-13) in the open surgery group and 3.1 (0-8) in the laparoscopy group (p=0.216). The laparoscopy group exhibited a longer operation time (281.2±54.2 and 221.0±51.5 min, respectively; P=0.036) than the open surgery group, but a shorter intensive care unit(ICU) discharge, quicker initiation oral feeding, and shorter length of hospital stay (4.0±0.9 vs. 5.7±2.0 days, respectively; P<0.001). Discussion: Laparoscopic surgery elicits many benefits such as less wound infection, lower requirement for blood transfusion, shorter hospitalization, quicker initiation of oral feeding and mobilization. Our study has shown that laparoscopic surgery provides quite adequate lymph node dissection when compared with oncological surgery, which is viewed with suspicion in the light of these benefits of laparoscopy.

The Rise in Norovirus-Related Acute Gastroenteritis During the Fight Against the COVID-19 Pandemic in Southern China

Background: There has been a significant decline in the morbidity of almost all infectious diseases during the COVID-19 pandemic. However, while the incidence of norovirus-related acute gastroenteritis declined in Guangzhou, China during the initial period of the pandemic, incidence increased significantly once the new school year began in September 2020.Methods: Norovirus-related acute gastroenteritis clusters and outbreaks were assessed in Guangzhou from 2015 to 2020. Medians and interquartile ranges were compared between groups using the Mann–Whitney U-test, and attack rates were calculated.Results: While 78,579 cases of infectious diarrhea were reported from 2015 to 2019, with an average of 15,716 cases per year, only 12,065 cases of infectious diarrhea were reported in 2020. The numbers of sporadic cases and outbreaks reported from January to August 2020 were lower than the average numbers reported during the same time period each year from 2015 to 2019 but began to increase in September 2020. The number of cases in each reported cluster ranged from 10 to 70 in 2020, with a total of 1,280 cases and an average attack rate of 5.85%. The median number of reported cases, the cumulative number of cases, and the attack rate were higher than the average number reported each year from 2015 to 2019. The intervention time in 2020 was also higher than the average intervention time reported during 2015–2019. The main norovirus genotypes circulating in Guangzhou during 2015–2020 included genogroup 2 type 2 (GII.2) (n = 79, 26.69%), GII.17 (n = 36, 12.16%), GII.3 (n = 27, 9.12%), GII.6 (n = 8, 2.7%), GII.4 Sydney_2012 (n = 7, 2.36%), and GII.4 (n = 6, 2.03%).Conclusions: Our findings illustrate the importance of maintaining epidemiological surveillance for viral gastroenteritis during the COVID-19 pandemic. Local disease prevention and control institutions need to devote sufficient human resources to control norovirus clusters.

A review of COVID-19 transmission dynamics and clinical outcomes on cruise ships worldwide, January to October 2020

Background Cruise ships provide an ideal setting for transmission of SARS-CoV-2, given the socially dense exposure environment. Aim To provide a comprehensive review of COVID-19 outbreaks on cruise ships. Methods PubMed was searched for COVID-19 cases associated with cruise ships between January and October 2020. A list of cruise ships with COVID-19 was cross-referenced with the United States Centers for Disease Control and Prevention’s list of cruise ships associated with a COVID-19 case within 14 days of disembarkation. News articles were also searched for epidemiological information. Narratives of COVID-19 outbreaks on ships with over 100 cases are presented. Results Seventy-nine ships and 104 unique voyages were associated with COVID-19 cases before 1 October 2020. Nineteen ships had more than one voyage with a case of COVID-19. The median number of cases per ship was three (interquartile range (IQR): 1–17.8), with two notable outliers: the Diamond Princess and the Ruby Princess, which had 712 and 907 cases, respectively. The median attack rate for COVID-19 was 0.2% (IQR: 0.03–1.5), although this distribution was right-skewed with a mean attack rate of 3.7%; 25.9% (27/104) of voyages had at least one COVID-19-associated death. Outbreaks involving only crew occurred later than outbreaks involving guests and crew. Conclusions In the absence of mitigation measures, COVID-19 can spread easily on cruise ships in a susceptible population because of the confined space and high-density contact networks. This environment can create superspreader events and facilitate international spread.

Contacts with general practitioners, dentists, and medical specialists among nursing home residents: a cross-sectional study in 44 German nursing homes

Background Nursing home residents have high medical care needs. Their medical care utilization is, however, lower compared to community-dwelling elderly and varies widely among nursing homes. This study quantified the utilization of general practitioners (GPs), dentists, and medical specialists among nursing homes and residents, and investigated whether dentist utilization is associated with individual and nursing home characteristics. Methods Forty-four nursing homes invited 2124 residents to participate in a cross-sectional study. For 10 medical specialties, data on contacts in nursing homes, practices, and by telephone in the last 12 months were assessed at individual and nursing home level. The proportion of nursing homes and residents with any form of contact, and the median number and interquartile range (IQR) of contacts among individuals with contact were determined. Using multilevel logistic regression, associations between the probability of individual dental care utilization and sex, age, LTC grade, years of residence, sponsorship, number of nursing home beds, and transport and medical escort services for consultations at a practice were investigated. Results The proportion of nursing homes with any form of contact with physicians ranged from 100% for GPs, dentists, and urologists to 76.7% for gynecologists and orthopedists. Among the nursing homes, 442 residents participated (20.8% response). The proportion of residents with any contact varied from 97.8% for GPs, 38.5% for neurologists/psychiatrists, and 32.3% for dentists to 3.0% for gynecologists. Only for GPs, neurologists/psychiatrists, dentists, otorhinolaryngologists, urologists, and dermatologists, the proportion was higher for nursing home contacts than for practice and telephone contacts. Among residents with any contact, the median number of contacts was highest for GPs (11.0 [IQR 7.0-16.0]), urologists (4.0 [IQR 2.0-7.0]), and neurologists/psychiatrists (3.0 [IQR 2.0-5.0]). Dentist utilization varied widely among nursing homes (median odds ratio 2.5) and was associated with higher age. Conclusions Almost all residents had regular contact to GPs, but only one third had contact with dentists. Lower proportions with contact were found for medical specialists, except for neurologists/psychiatrists. Reasons for the large variations in dental care utilization among nursing homes should be identified. Trial registration DRKS00012383 [2017/12/06].

Does a physiology-based interpretation of CTG allow to dispense with second-line methods? A cross-sectional online survey

Objective: To determine the influence of a training course in physiology-based interpretation of cardiotocography (CTG) on professional practices. Design: A cross-sectional study. Setting: A national online survey. Population: Fifty-seven French obstetricians Methods: The participants were divided into two groups: the training group (obstetricians who had already participated in a training course in physiology-based interpretation of CTG) and the control group. Ten medical records of patients who had abnormal CTG tracings and underwent a foetal scalp blood sampling (pH) during labour were presented to the participants. They were given three choices: (i) use a second-line method, (ii) continue labour without using a second-line method, or (iii) perform a caesarean section. Main outcome measures: Median number of decisions to use second-line methods. Results: Forty participants were included in the training group and 17 in the control group. The median number of recourses to a second-line method was significantly inferior for the training group (4 [2–6] second-line methods on 10 records) than for the control group (6 [4–7]; p = 0.040). Regarding the 4 records for which a caesarean section was the real outcome, the median number of decisions of continuing labour was significantly superior in the training group than in the control group (1 [0–1] vs. 0 [0–1]; p = 0.032). Conclusions: Participation in a training course in physiology-based interpretation of CTG could be associated with a less frequent use of second-line methods. Additional studies are required to determine whether this change in attitude is safe for the foetal well-being.

Decreasing Laboratory Testing for Neonatal Jaundice Through Revision of a Clinical Practice Pathway

OBJECTIVES: The purpose of this study was to minimize unnecessary laboratory services for hospitalized neonates with hyperbilirubinemia by revising a local clinical practice pathway (CPP). METHODS: A retrospective cohort study was performed to compare the number of laboratory tests and blood draws in patients hospitalized with neonatal hyperbilirubinemia before and after implementation of a revised CPP. The study included infants with neonatal hyperbilirubinemia &lt;14 days old admitted after their birth hospitalization between April 2017 and October 2019. Primary outcome measures included the total number of blood draws and the number of laboratory tests obtained per patient and length of stay. Secondary outcome measures included 7-day readmission rate, charges, and discharge bilirubin level. RESULTS: The median number of blood draws per patient after implementation of the CPP decreased to 2 (interquartile range [IQR], 2–3) compared with 3 (IQR, 2–3) before implementation (Poisson model–based estimated mean difference, 1.1; 95% confidence interval, 1.0–1.3; P = .018). The median number of laboratory tests per patient after implementation decreased from 4 (IQR, 3–6) to 3 (IQR, 2–4; Poisson model–based estimated mean difference, 1.3; 95% confidence interval, 1.2–1.5; P &lt; .0001). There was no significant change in length of stay, readmission rate, charges, or discharge bilirubin level. CONCLUSIONS: Implementation of a revised CPP was associated with a significant decrease in the number of blood draws and laboratory tests per patient for infants admitted to the hospital for neonatal hyperbilirubinemia.

TRANSFUSION PRACTICE, POST-TRANSFUSION COMPLICATIONS AND RISK FACTORS IN SICKLE CELL DISEASE IN SENEGAL, WEST AFRICA.

Context and Objectives: Blood transfusions (BT) remain a mainstay of therapy for patients with sickle cell disease (SCD), but pose significant clinical challenges. We aim to assess infectious markers, red cell alloimmunization and iron overload secondary to BT in SCD patients. Materials and Methods: This is a case-control study included 253 SCD (153 SCD-transfused and 100 SCD non-transfused). We evaluated the transfusion practice (modalities, indications), post-transfusion complications (infections, alloimmunization, iron overload) and risk factors of these complications (socio-demographic, clinical, biological). Results: Median age was 28.5 years (5 - 59). Sex ratio was 0.86. Homozygous SCD was more common (95.3%). Simple BT was performed in 92.8% and transfusion exchange in 18.9%. Transfusion indications were dominated by acute anemia (57.06%) and vaso-occlusive crisis (VOCs) (14%). Red blood cell concentrates (RBC) were administered to 93.46%. Median number of RBC received per patient was 10 (2 - 48). The prevalence of VHC in SCD-transfused was 1.33% and 2% for VHB. Anti-HIV antibodies were not found. Red cell alloimmunization frequency was 16%. The most common alloantibodies were anti-rhesus (34.19%) and anti-Kell (23.67%). Iron overload was detected in 7.84%. The number of RBC transfused was the only risk factor for alloimmunization (p = 0.03) and iron overload (p = 0.023). BT frequency was not related to infectious transmission. Conclusion: Despite advances in blood safety, BT therapy is still a risk for SCD polytransfused patients. Although infectious transmission has rare, the risk of alloimmunization and iron overload is high in these patients.

Study of Gemcitabine Plus Nab-Paclitaxel-Based Chemotherapy Regimen as First-Line Treatment in Metastatic Pancreatic Carcinoma

Background The purpose of this study was to study the effectiveness of gemcitabine and nab-paclitaxel combination as first-line chemotherapy regimen for the treatment of metastatic pancreatic cancer. There is scarcity of data regarding efficacy and toxicity profile of this combination in Indian population. Aims and Objectives The primary aim of this study was to assess efficacy of this regimen, for which evaluation done in terms of the objective response rate, progression-free survival (PFS), and overall survival. Safety data were also evaluated. Materials and Methods In this prospective study, gemcitabine plus nab-paclitaxel combination chemotherapy was given as first line in metastatic pancreatic carcinoma patients till progression or appearance of grade 3/4 toxicities with treatment. Results The study was performed in 30 patients comprising 18 (60%) males and 12 (40%) females. The median age was 60 years. Median number of cycles administered were six cycles per patient. Seventeen patients (56.67%) had a partial response and 0% had complete response. A total of seven (23.3%) patients progressed on chemotherapy and six (20%) had stable disease (SD). The disease control rate (responses and SD) was 76.7%. The median PFS was 5.75 months. There was no statistically significant difference in terms of response rates and baseline CA 19-9 levels. Most common toxicities were hematological toxicities with rates of grade 3/4 anemia and neutropenia of 20%. Among nonhematological toxicities, nausea (46.67%) and fatigue (30%) were the commonest. Conclusion Combination of gemcitabine and nab-paclitaxel is active and well tolerated in advanced pancreatic carcinoma. To the best of our knowledge, this is the first such study conducted in India.

Years Since Diagnosis Among People Living With Diagnosed HIV in New York City

Antiretroviral treatment has greatly improved the survival of people living with diagnosed HIV (PLWDH), but little information is available on the time since diagnosis among them. Using New York City HIV surveillance data, we described the trend in the number of years since diagnosis among PLWDH during 2010-2019 and reported the mean, median, and interquartile range (IQR) of years since diagnosis among PLWDH in New York City in 2019, overall and by gender, race and ethnicity, and transmission risk. The median number of years since diagnosis among PLWDH in New York City increased from 10.5 years (IQR, 6.3-15.6) in 2010 to 16.3 years (IQR, 8.9-22.1) in 2019. By gender, transgender people had the shortest time since diagnosis, with a median of 11.4 years (IQR, 5.6-17.9), compared with men (median = 15.2 years; IQR, 8.1-21.6) and women (median, 18.5 years; IQR, 12.0-23.0). By race and ethnicity, non-Hispanic White people had been living with the diagnosis for the longest time (median = 17.4 years; IQR, 9.5-23.5), and Asian/Pacific Islander people had been living with the diagnosis for the shortest time (median = 10.1 years; IQR, 4.7-17.0). With an expected and continuing increase in the number of years since HIV diagnosis among PLWDH, programs that provide treatment and support services will need to be expanded, updated, and improved.
