Purpose:
Splenic flexure mobilization (SFM) is occasionally utilized during sigmoidectomy to facilitate a tension-free colorectal anastomosis. Present literature regarding its use, safety, and efficacy predominantly evaluates traditional laparoscopic vs. open techniques, thus not adequately representing the current minimally invasive surgical landscape.
Methods:
This retrospective cohort analysis evaluated SFM during sigmoidectomy for diverticular disease via traditional laparoscopic, single-incision laparoscopic, and robotic techniques at a United States academic institution from 2019 to 2022. Primary outcomes were the rate of SFM, independent predictors, and short-term outcomes.
Results:
A total of 117 patients underwent sigmoidectomy for diverticulitis by six colorectal surgeons, of whom 27 underwent SFM. SFM was associated with higher rates of complicated diverticulitis (85.2% vs. 46.7%, p < 0.001), including abscess (55.6% vs. 33.3%, p = 0.037) and fistulae (59.3% vs. 17.8%, p < 0.001). Presence of a fistula was an independent predictor of SFM by logistic regression (odds ratio [OR], 5.886; p < 0.001). Mobilization was associated with more concomitant surgical procedures (66.7% vs. 28.9%, p < 0.001). There was a significant association between SFM and conversion to open approach (14.8% vs. 3.3%, p = 0.049), longer length of stay (4.2 ± 2.8 days vs. 3.6 ± 4.3 days, p = 0.041), and increased operative time (241.7 ± 76.4 minutes vs. 199.2 ± 75.7 minutes). There was no difference in 30-day morbidity/mortality.
Conclusion
Routine SFM can be considered in minimally invasive sigmoidectomy for complicated diverticulitis without significant impact on 30-day morbidity/mortality regardless of surgical approach and may be anticipated preoperatively, particularly when a fistula is present.

Background:
Centenarians are considered the most successful human biological aging model. However, the characteristics and patterns of research among centenarians have not been described or analyzed. Thus, this study aimed to disclose the historical landscape of global research on centenarians.
Methods:
This bibliometric study investigated historical evidence on centenarian research published in the Scopus database. The bibliometrix package in R was used to perform visual and quantitative analyses of research metrics, trends, and patterns.
Results:
Of the 2,061 documents included between 1887 and 2023, 84.2% (n=1,736) were published as articles with primary data. We identified international collaboration and annual growth rates of 21.4% and 3.15%, respectively. The United States published the highest number of papers on centenarians (n=786), whereas the publications from Italy had the highest impact (h-index of 90). Based on the frequency of keywords, mortality, genetics, dementia, Alzheimer’s disease, and immunosenescence are a few of the most studied topics among centenarians, with emerging research related to mitochondrial DNA and comparison of results between nonagenarians and centenarians. Italy, the United States, and China lead the global research collaboration network, collaborating most frequently with Japan and European countries.
Conclusion
Global research on centenarians has grown over the last 20 years, primarily led by Italy, the United States, and China. Latin American and African countries have conducted little or no research on centenarians. The most widely studied topics include mortality, cognition, immunosenescence, and genetics.

Objective: In Viet Nam, tuberculosis (TB) prevalence surveys revealed that approximately 98% of individuals with pulmonary TB have TB-presumptive abnormalities on chest radiographs, while 32% have no TB symptoms. This prompted the adoption of the “Double X” strategy, which combines chest radiographs and computer-aided detection with GeneXpert testing to screen for and diagnose TB among vulnerable populations. The aim of this study was to describe demographic, clinical and radiographic characteristics of symptomatic and asymptomatic Double X participants and to assess multilabel radiographic abnormalities on chest radiographs, interpreted by computer-aided detection software, as a possible tool for detecting TB-presumptive abnormalities, particularly for subclinical TB.
Methods: Double X participants with TB-presumptive chest radiographs and/or TB symptoms and known risks were referred for confirmatory GeneXpert testing. The demographic and clinical characteristics of all Double X participants and the subset with confirmed TB were summarized. Univariate and multivariable logistic regression modelling was used to evaluate associations between participant characteristics and subclinical TB and between computer-aided detection multilabel radiographic abnormalities and TB.
Results: From 2020 to 2022, 96 631 participants received chest radiographs, with 67 881 (70.2%) reporting no TB symptoms. Among 1144 individuals with Xpert-confirmed TB, 51.0% were subclinical. Subclinical TB prevalence was higher in older age groups, non-smokers, those previously treated for TB and the northern region. Among 11 computer-aided detection multilabel radiographic abnormalities, fibrosis was associated with higher odds of subclinical TB.
Discussion: In Viet Nam, Double X community case finding detected pulmonary TB, including subclinical TB. Computer-aided detection software may have the potential to identify subclinical TB on chest radiographs by classifying multilabel radiographic abnormalities, but further research is needed.

Most medical complications following acute stroke are preventable (such
as cardiac events, pneumonia, bed sores and venous thrombosis). This was a study on the frequency
of medical complications and their association with key performance indicators. Methods: The study
used a cross-sectional baseline audit of stroke care practices. The audit captured details on the nature
of the stroke, patient demographics, characteristics of hospital care, and compliance with six key
quality indicators in Philippine Academy of Rehabilitation Medicine Clinical Practice Guideline on
Stroke Rehabilitation. Patient records were retrospectively consecutively sampled. Results: A total
of 1,683 patients were included in the audit which came from 49 hospitals. Medical complications
were seen in 182 patients (11.2%). Pneumonia contributed to half the medical complications (50%),
followed by respiratory failure (7.7%) and gastrointestinal bleeding (3.8%). Presence of medical
complications were associated with in-patient mortality (OR 3.3 (95% CI 2.1-5.3)) and prolonged
hospital stay (16.1 ± 20.7 days vs 9.6 + 10.9 days). The best predictor model for pneumonia included
variables of not having a swallow screen within the first 24 hours, having a nasogastric tube inserted,
not achieving medical stability, not having a stroke unit in the admitting hospital, having suffered a
previous stroke and being older.
Conclusion: Non-adherence to evidence-based stroke care rehabilitation guidelines contributed
significantly to medical complications in an audit of Filipino stroke patients

BACKGROUNDBrazil is among the nations with the greatest rates of annual cocaine usage. Pharmacological treatment of cocaine addiction is still limited, opening space for nonconventional interventions. Homeopathic Q-potencies of opium and Erythroxylum coca have been tested in the integrative treatment of cocaine craving among homeless addicts, but this setting had not proven feasible, due to insufficient recruitment.
OBJECTIVEThis study investigates the effectiveness and tolerability of homeopathic Q-potencies of opium and E. coca in the integrative treatment of cocaine craving in a community-based psychosocial rehabilitation setting.
DESIGN, SETTING, PARTICIPANTS, AND INTERVENTIONSA randomized, double-blind, placebo-controlled, parallel-group, eight-week pilot trial was performed at the Psychosocial Attention Center for Alcohol and Other Drugs (CAPS-AD), Sao Carlos/SP, Brazil. Eligible subjects included CAPS-AD patients between 18 and 65 years of age, with an International Classification of Diseases-10 diagnosis of cocaine dependence (F14.2). The patients were randomly assigned to two treatment groups: psychosocial rehabilitation plus homeopathic Q-potencies of opium and E. coca (homeopathy group), and psychosocial rehabilitation plus indistinguishable placebo (placebo group).
MAIN OUTCOME MEASURESThe main outcome measure was the percentage of cocaine-using days. Secondary measures were the Minnesota Cocaine Craving Scale and 12-Item Short-Form Health Survey scores. Adverse events were reported in both groups.
RESULTSThe study population comprised 54 patients who attended at least one post-baseline assessment, out of the 104 subjects initially enrolled. The mean percentage of cocaine-using days in the homeopathy group was 18.1% (standard deviation (SD): 22.3%), compared to 29.8% (SD: 30.6%) in the placebo group (P < 0.01). Analysis of the Minnesota Cocaine Craving Scale scores showed no between-group differences in the intensity of cravings, but results significantly favored homeopathy over placebo in the proportion of weeks without craving episodes and the patients' appraisal of treatment efficacy for reduction of cravings. Analysis of 12-Item Short-Form Health Survey scores found no significant differences. Few adverse events were reported: 0.57 adverse events/patient in the homeopathy group compared to 0.69 adverse events/patient in the placebo group (P = 0.41).
CONCLUSIONSA psychosocial rehabilitation setting improved recruitment but was not sufficient to decrease dropout frequency among Brazilian cocaine treatment seekers. Psychosocial rehabilitation plus homeopathic Q-potencies of opium and E. coca were more effective than psychosocial rehabilitation alone in reducing cocaine cravings. Due to high dropout rate and risk of bias, further research is required to confirm our findings, with specific focus on strategies to increase patient retention.

BACKGROUND/AIMS: Lipopolysaccharide (LPS) is a molecule formed by lipids and polysaccharides and is the major cell wall component of gram-negative bacteria. High LPS levels are known to block CD26 expression by activating Toll-like receptor 4. The aim of this study was to correlate the serum levels of LPS and CD26 in Crohn's disease (CD) patients with serum levels of C-reactive protein (CRP), interleukins, CD activity index, and tumor necrosis factor-α (TNF-α). METHODS: Serum samples were collected from 27 individuals (10 with active CD, 10 with inactive CD, and 7 controls) and the levels of LPS, CD26, TNF-α, interleukin-1β (IL-1β), IL-6, IL-17, and CRP were determined by enzyme-linked immunosorbent assay. The levels of LPS and CD26 were then tested for correlation with TNF-α, IL-1β, IL-6, IL-17, and CRP. RESULTS: Serum levels of LPS were significantly elevated in the active CD group (P=0.003). Levels of IL-1β (P=0.002), IL-6 (P=0.003), and IL-17 (P<0.001) were lower in the CD groups. Serum TNF-α levels were increased in the active CD group. The CRP levels were elevated in the CD groups when compared to controls (P<0.001). The CD26 levels were lower in the CD groups than in the control group (P<0.001). Among the variables analyzed, there was a correlation between LPS and CRP (r=−0.53, P=0.016) in the CD groups. CONCLUSIONS: Individuals with CD exhibited higher serum levels of LPS varying from a 2- to 6-fold increase depending on disease activity, when compared with healthy controls. CD26 levels were lower in the CD groups. Both LPS and CD26 correlated with disease severity and serve as potential CD biomarkers.
