Perioperative sildenafil therapy in pulmonary hypertension associated with congenital cardiac disease: An updated meta-analysis.

To provide an updated meta-analysis to evaluate the efficacy and safety of sildenafil on pediatric patients with pulmonary hypertension (PH) associated with congenital heart disease (CHD). To assess the efficacy and safety of sildenafil, five outcomes, time duration of post-operative need for mechanical ventilation, time duration of post-operative ICU stay, length of hospitalization (LOH), the incidence of mortalities and pulmonary arterial pressure to aortic pressure ratio (PAP/AoP) were regarded as primary efficacy outcomes. Standardized mean difference (SMD) was calculated for continuous data. In comparison to the control group (CG), there was a significant decrease in the time duration of ICU stay in the sildenafil group (SG) (SMD = -0.61 [95% CI -1.17, 0.04]; P < 0.01, I2 = 85%). Length of hospitalization was assessed in the sildenafil and control groups (SMD = -0.18 [95% CI -0.67, 0.31] P = 0.05, I2 = 62%). However, there was no significant difference seen in mortality rates between the SG and CG (SMD = 0.53 [ 95% CI 0.13, 2.17] p = 0.61, I2 = 0%), in the time duration of postoperative mechanical ventilation between the SG and CG (SMD = -0.23 [95% CI -0.49, 0.03] p = 0.29, I2 = 19%), or PAP/AoP ratio between the SG and CG (SMD = -0.42 [95% CI -1.35, 0.51] P < 0.01, I2 = 90%). Based on our analysis, sildenafil has little to no effect in reducing postoperative morbidity and mortality due to PH in infants and children with CHD.

Time to treatment disparities in gastric cancer patients in the United States of America: a comprehensive retrospective analysis.

Introduction: Gastric cancer ranks as the 5th most prevalent cancer and the 4th leading cause of cancer-related deaths worldwide. Various treatment modalities, including surgical resection, chemotherapy, and radiotherapy, are available for gastric cancer patients. However, disparities related to age, sex, race, socioeconomic factors, insurance status, and demographic factors often lead to delayed time to treatment. Methods: In this retrospective study, conducted between 2004 and 2019, we utilized data from the National Cancer Database (NCDB) to investigate the factors contributing to disparities in the time to first treatment, surgery, chemotherapy, and radiotherapy among gastric cancer patients. Our analysis incorporated several variables, and statistical analysis was conducted to provide valuable insights into these disparities. Results: We observed notable disparities in the timing of treatment for various demographic groups, including age, sex, race, insurance status, geographic location, and facility type. These disparities include longer time to treatment in males (32.67 vs 30.75), Native Americans (35.10 vs 31.09 in Asians), low-income patients (32 vs 31.15), patients getting treatment in an academic setting (36.11 vs 29.61 in community setting), significantly longer time to chemotherapy in 70+ age group (51.13 vs 40.38 in <40 y age group), black race (55.81 vs 47.05 in whites), low income people (49.64 vs 46.74), significantly longer time to radiotherapy in females (101.61 vs 79.75), blacks and Asians (109.68 and 113.96 respectively vs 92.68 in Native Americans) etc. There are various other disparities in time to surgery, chemotherapy, and radiotherapy. Conclusions: Understanding these disparities is crucial in developing targeted strategies to improve timely access to appropriate treatments and enhance outcomes for gastric cancer patients. Future research with updated data and prospective study designs can provide a more comprehensive understanding of the factors influencing patient outcomes in gastric cancer.

Efficacy and safety of bedaquiline and delamanid in the treatment of drug-resistant tuberculosis in adults: A systematic review and meta-analysis.

Multi and extensively drug-resistant tuberculosis is a grave cause of global public health concern due to its high mortality and limited treatment options. We conducted this systemic review and meta-analysis to evaluate the efficacy and safety of bedaquiline and delamanid, which have been added to the WHO-recommended regimen for treating drug-resistant tuberculosis. Electronic databases were searched from their inception until December 1st, 2021, for eligible studies assessing the efficacy and safety of bedaquiline and delamanid for treating drug-resistant tuberculosis. Binary outcomes were pooled using a DerSimonian-Laird random-effects model and arcsine transformation and reported on a log scale with a 95% confidence interval (CIs). Twenty-one studies were shortlisted in which bedaquiline, delamanid, and a combination of both were administered in 2477, 937, and 169 patients. Pooled culture conversion at 6 months was 0.801 (p < 0.001), 0.849 (p = 0.059) for bedaquiline and delamanid, respectively, and 0.823 (p = 0.017), concomitantly. In the bedaquiline cohort, the pooled proportion of all-cause mortality at 6 months was reported as 0.074 (p < 0.001), 0.031 (p = 0.372) in the delamanid cohort, and 0.172 in the combined cohort. The incidence of adverse events in the bedaquiline cohort ranged from 11.1% to 95.2%, from 13.2% to 86.2% in the delamanid cohort, and 92.5% in a study in the combined cohort. The incidence of QTC prolongation reported in each cohort is as follows: bedaquiline 0.163 (p < 0.001), delamanid 0.344 (p = 0.272) and combined 0.340 (p < 0.001). Our review establishes the efficacy of delamanid, bedaquiline, and their combined use in treating drug-resistant tuberculosis with reasonable rates of culture conversion, low mortality rates, and safety of co-administration, as seen with their effect on the QTc interval.

Inequities in Time to Treat Thyroid Cancer.

BACKGROUND/AIM: The purpose of this study was to determine socioeconomic and demographic factors which may contribute to inequities in time to treat thyroid cancer. PATIENTS AND METHODS: We used data from the National Cancer Database, 2004-2019, to conduct an analysis of thyroid cancer patients. All (434,083) patients with thyroid cancer, including papillary (395,598), follicular (23,494), medullary (7,638), and anaplastic (7,353) types were included. We compared the wait time from diagnosis to first treatment, surgery, radiotherapy, and chemotherapy for patients based on age, race, sex, location, and socioeconomic status (SES). RESULTS: A total of 434,083 patients with thyroid cancer were included. Hispanic patients had significantly longer wait times to all treatments compared to non-Hispanic patients (first treatment 33.44 vs. 20.45 days, surgery 40.06 vs. 26.49 days, radiotherapy 114.68 vs. 96.42 days, chemotherapy 92.70 vs. 58.71 days). Uninsured patients, patients at academic facilities, and patients in metropolitan areas also had the longest wait times to treatment. CONCLUSION: This study identified multiple disparities related to SES and demographics that correspond to delays in time to treatment. It is crucial that this topic is investigated further to help mitigate these incongruities in thyroid cancer care in the future.

Sociodemographic Barriers to the Timely Treatment of Pancreatic Cancer.

BACKGROUND/AIM: Pancreatic cancer has a high mortality rate and timely treatment is imperative for favorable patient outcomes. This retrospective study aimed to identify disparities in time to treatment for pancreatic cancer based on sociodemographic factors. PATIENTS AND METHODS: The study used the National Cancer Database from 2004 to 2019. A total of 423,482 patients with pancreatic cancer were included in the study. Time to first treatment, surgery, radiation, and chemotherapy were analyzed in the context of age, sex, race, Hispanic origin, insurance status, income, facility type, geographic setting, grade, stage, and Charlson-Deyo Comorbidity score (CDC). RESULTS: All sociodemographic factors included were found to be significantly associated with disparities for time to treatment in at least one of the categories studied. Minorities, treatment at academic facilities, and patients with a high CDC score had consistently longer times to all treatment classifications. CONCLUSION: The analyzed sociodemographic factors affected time to pancreatic cancer treatment. Disparities in time to treatment for pancreatic cancer must be studied and understood to ameliorate the impact this cancer has on society and assure the best possible care for all communities.

Disparities in Time to Treatment for Skin Cancer.

BACKGROUND/AIM: Skin cancer is the most common cancer worldwide. This study aimed to identify factors contributing to the disparities in skin cancer treatment. PATIENTS AND METHODS: Data from The National Cancer Database (NCDB) spanning 2004 to 2019 were utilized. Variables including age, sex, race, Hispanic origin, Charlson-Deyo Comorbidity (CDC) score, geographic location, insurance status, income, grade and stage of cancer, and type of treatment facility impacting the time to treatment, surgery, radiation, and chemotherapy were analyzed. RESULTS: Trends of longer time to treatment were seen with older age, non-Hispanic white, uninsured, those with a higher CDC score, and treated at academic facilities. Additionally, annual income and clinicopathology of cancer were also significantly associated with time to treatment. CONCLUSION: Our findings contribute to the expanding body of evidence pointing to the influence of socioeconomic and demographic factors in treatment disparities across diverse patient populations.

The Virtual Face of Colon and Rectal Surgery Training in the USA: An In-Depth Evaluation and Analysis of Fellowship Programs Website Content.

BACKGROUND: With an ever-evolving digital and virtual world hastened by the COVID-19 pandemic, prospective colon and rectal surgery fellowship applicants must rely on online sources of information, such as websites, rather than in-person visits to fellowship programs. This study analyzes and evaluates the content and accuracy of colon and rectal surgery fellowship program websites. METHODS: The Fellowship and Residency Electronic and Interactive Database website provides a complete collection of colon and rectal surgery fellowship websites based in the USA. The accessibility of the websites was verified via Google search, and relevant content for the applicants was evaluated based on 50-point criteria. RESULTS: Analysis of 60 fellowship program websites was conducted, out of which only a fifth (20%) were kept up to date. Twenty-seven (45%) websites fulfilled 50% of the 50-point criteria. The most and least included data points were program overview (69%) and residential/housing information (24%). Most websites contained basic information relevant to international applicants but lacked crucial information such as visa sponsorship (12%) and city information (23%). CONCLUSION: An informative and easily accessible website is essential for prospective applicants to choose the best program for their career goals and academic needs. This study highlighted multiple areas for potential improvement in the colon and rectal surgery program websites. Individual colon and rectal surgery programs may benefit and attract more candidates to their programs through a fully optimized website design and content.

Role of laparoscopic surgery in the management of gallbladder cancer: Systematic review & meta-analysis.

BACKGROUND: This meta-analysis evaluates the safety and short-term oncological outcomes of laparoscopic vs. open surgery for gallbladder carcinoma(GBC). METHODS: Meta-analysis was performed on laparoscopic(LG) and open group(OG) studies. Data for survival outcomes were extracted from Kaplan-Meier curves and combined with Tierney's method to estimate hazard ratios(HRs) and 95% CIs. RESULTS: There was no significant difference in overall survival(HR: 1.01), disease-free survival(HR: 0.84), 30-day mortality(RR:1.10), overall recurrence(RR:0.93), intraoperative gallbladder violation(RR:1.17), operative time(WMD:8.32), number of patients receiving adjuvant chemotherapy(RR:1.06) and blood transfusion(RR: 0.81). A significant difference was seen in survival of T3 subgroup(HR:0.77) and number of lymph node dissections (LND)(WMD: 0.63) favoring OG, along with a decrease in postoperative complications(RR:0.65), greater incidence of R0 resections(RR:1.04), lower volume of intraoperative blood loss(WMD: 128.62), lower time in removing drainage tube(WMD: 1.35), shorter diet recovery time(WMD: 1.88), shorter hospital stay(WMD: 3.51), lower incidence of 90-day mortality(RR:0.49) favoring LG. A higher incidence of port-site recurrence(RR:1.99) was reported in LG. CONCLUSION: Laparoscopic surgery is non-inferior to the open approach in terms of oncological outcomes and has an improved rate of postoperative complications.
