Urinary tract infections (UTIs) are one of the most common infections in the United States and consequently are responsible for significant healthcare expenditure. The standard urine culture is the current gold standard for diagnosing urinary tract infections, however there are limitations of the test that directly contribute to increased healthcare costs. As a result, new and innovative techniques have been developed to address the inefficiencies of the current standard—it remains to be seen whether these tests should be performed adjunctly to, or perhaps even replace the urine culture. This review aims to analyze the advantages and disadvantages of the newer and emerging diagnostic techniques such as PCR, expanded quantitative urine culture (EQUC), and next generation sequencing (NGS).

Introduction and hypothesisUreteral injury during gynecological surgery can be managed in a variety of ways, from endoscopic stent placement to ureteroneocystotomy with accompanying psoas hitch and/or Boari flap. The majority of these occur during hysterectomy; therefore, gynecologic surgeons may not be as familiar with repair in women with intact uteri. Herein we present our technique for delayed robotic-assisted ureteral reimplant and psoas hitch in a woman with a ureteral injury sustained during cesarean section, which initially presented as a uretero-cervical fistula.MethodsIn this video, we describe the evaluation and surgical management of a patient with delayed recognition of a left distal ureteral injury sustained during cesarean section. We present necessary modifications to robotic-assisted laparoscopic ureteroneocystostomy and psoas hitch to accommodate an intact uterus including the need for uterine manipulation, division of the round ligament, bladder mobilization from the lower uterine segment and development of the retropubic space, reimplantation steps, and psoas hitch.ConclusionsSimple modifications to a traditional technique of robotic-assisted ureteroneocystotomy effectively compensate for the presence of a uterus. Obstetricians should maintain a high index of suspicion for ureteral injury in women with new-onset severe urinary leakage post-cesarean section.

Introduction and hypothesisThe posterior approach to sacrospinous hysteropexy has been well studied but little is known about the anterior approach. This study assessed the efficacy and complications of an anterior approach to sacrospinous hysteropexy compared to hysterectomy with apical repair. We hypothesized that anterior sacrospinous hysteropexy has similar efficacy and fewer complications.MethodsThis retrospective cohort study compared patients who underwent native-tissue anterior sacrospinous hysteropexy (cases) with those who underwent hysterectomy with apical repair (controls). Composite success was defined as (1) leading edge of prolapse not beyond the hymen and apex not descended > 1/3 total vaginal length; (2) no vaginal bulge symptoms; (3) no prolapse retreatment. Descriptive and bivariate statistics were performed as well as a Cox regression analysis for time to failure.ResultsFifty cases and 97 controls were compared. The median follow-up time was 7.6 months. Operative time was shorter in the hysteropexy group (110.7 vs. 155.9 min, p < 0.001). The composite success was 92% for both cases and controls (p = 1.000) with no difference in time to surgical failure (p = 0.183). There were no serious intraoperative complications in the hysteropexy group and six in the control group (3 transfusions, 1 conversion to laparotomy, 1 ureteral injury, 1 cystotomy; p = 0.101). There was no difference in the number of postoperative complications (22.0% vs. 30.9%, p = 0.203).ConclusionsFor primary uterine prolapse, anterior sacrospinous hysteropexy has similar short-term efficacy compared to hysterectomy with apical repair with shorter operative time and a trend towards fewer serious complications.

The present study aims at providing a novel technique for assessment of heavy metal contamination in a water body employing information entropy. For this purpose, 8 different locations, each from four tributaries of Brahmaputra river, Beki, Manas, Baralia and Pagladia, were chosen. Water samples from these tributaries were collected and analyzed for iron (Fe), manganese (Mn), lead (Pb), chromium (Cr), zinc (Zn) and copper (Cu) using atomic absorption spectroscopy (AAS). Information (Shannon) entropy was employed to assign weights to each heavy metal which was then coupled with the sub-indices to evaluate the entropy weighted heavy metal contamination index (EHCI). Spatial trend of EHCI values indicated that the water quality of Beki and Baralia river was either “excellent” (EHCI < 50) or “good” (50 < EHCI < 100) quality, except at fifth location of Beki river (SSBeK5) and sixth location of Baralia river (SPBR6). In Manas river water quality at upstream locations (SSMR1 and SSMR2) was “good,” and at all other locations, it was either “average” or below average quality (EHCI > 100). Similar trend was observed for Pagladia river. A comparative approach was also carried out among all the heavy metal contamination indices to decide the efficacy of EHCI. The results indicated major conflicts between the indices at various sampling locations, and thus, it was evident from the water quality dataset that EHCI provided a better insight to the classification of water quality with respect to heavy metals. The study would thus be of significant aid in scientific research of stream restoration and water treatment strategies.

Accredited Social Health Activists (ASHAs) are critical to extending health services to rural and underserved populations in India. Understanding what motivates these community health workers is essential for health organizations seeking to optimize their performance and retention. To explore factors affecting the motivation of ASHAs in Uttar Pradesh, India, from the perspectives of the ASHAs themselves. Qualitative in-depth interviews were conducted with 40 ASHAs across ten districts in Uttar Pradesh between September 6-24, 2023. ASHAs were selected based on the performance of their supervising ASHA Sanginis. Interviews were transcribed, translated from Hindi to English, and analyzed using thematic analysis in NVivo 12. Two categories of motivating factors emerged. Personal and community factors included self-efficacy from acquiring new knowledge, satisfaction from contributing to community health, increased autonomy and empowerment, and gaining respect within their communities. Organizational factors included training and skills development, supportive supervision from ASHA Sanginis, and financial incentives. While ASHAs remained positive about their work despite challenges, delayed payments and inadequate training were identified as key demotivating factors. Health organizations can leverage organizational factors - adequate and timely training, supportive supervision, well-stocked drug kits, and timely remuneration - to support ASHAs' intrinsic motivation. Failure to address these factors risks demotivation, reduced performance, and poorer health outcomes for the communities ASHAs serve.

Background: Dietary essential omega-6 (n-6) and omega-3 (n-3) 18 carbon (18C-) polyunsaturated fatty acids (PUFA), linoleic acid (LA) and α-linolenic acid (ALA), can be converted (utilizing desaturase and elongase enzymes encoded by FADS and ELOVL genes) to biologically-active long chain (LC; >20)-PUFAs by numerous cells and tissues. These n-6 and n-3 LC-PUFAs and their metabolites (ex, eicosanoids and endocannabinoids) play critical signaling and structural roles in almost all physiologic and pathophysiologic processes. Methods: This review summarizes: (1) the biosynthesis, metabolism and roles of LC-PUFAs; (2) the potential impact of rapidly altering the intake of dietary LA and ALA; (3) the genetics and evolution of LC-PUFA biosynthesis; (4) Gene–diet interactions that may lead to excess levels of n-6 LC-PUFAs and deficiencies of n-3 LC-PUFAs; and (5) opportunities for precision nutrition approaches to personalize n-3 LC-PUFA supplementation for individuals and populations. Conclusions: The rapid nature of transitions in 18C-PUFA exposure together with the genetic variation in the LC-PUFA biosynthetic pathway found in different populations make mal-adaptations a likely outcome of our current nutritional environment. Understanding this genetic variation in the context of 18C-PUFA dietary exposure should enable the development of individualized n-3 LC-PUFA supplementation regimens to prevent and manage human disease.

Endometriosis (ENDO), a chronic inflammatory disease affecting approximately 190 million women globally, is characterized by fibrosis, a feature often challenging to replicate in murine models. To identify an optimal syngeneic model exhibiting robust fibrosis and inflammation, we evaluated three inbred mouse strains: C57BL/6J ( n = 27), BALB/c ( n = 24), and Swiss albino ( n = 27). Uterine fragments from donor mice were intraperitoneally transplanted into recipient mice (1 donor: 2 recipients) using an established protocol with minor modifications. All ENDO-induced mice displayed reduced burrowing and exploratory behaviors, alongside increased mechanical hyperalgesia, indicative of ENDO-associated discomfort. Peritoneal fluid analysis revealed a pro-inflammatory environment with a tendency towards an M2 macrophage-dominant profile across all strains. Histological examination confirmed endometriotic lesions with proliferating epithelium (Ki-67+), neovascularization (CD31+), and macrophage infiltration (F4/80+). Notably, C57BL/6J mice exhibited the highest ENDO incidence and a significantly pronounced fibrotic response, evidenced by increased stromal collagen deposition and elevated Col1A1, cytokeratin, α-Smooth Muscle Actin (α-SMA), and Nestin expression. Molecular analysis in C57BL/6J mice further supported epithelial-mesenchymal transition (EMT)-driven fibrosis, with decreased E-cadherin and increased N-cadherin and S100A4 mRNA levels, corroborated by corresponding protein changes (cytokeratin, vimentin, snail). Our findings establish the C57BL/6J strain as the most suitable syngeneic model for ENDO, consistently recapitulating the inflammatory and fibrotic pathophysiology observed in human disease, particularly its fibrotic component.

Background Endometriosis (EM) is a persistent, chronic inflammatory condition associated with excruciating pelvic pain and infertility. The absence of a pre-clinical model that reliably replicates the clinical and functional hallmarks of human EM continues to limit progress in the domain. Furthermore, no rodent model developed to date has achieved a 100% incidence rate, compromising the reproducibility of existing models. Further, the inability to detect lesion development without sacrificing the animal presents a significant barrier for preclinical interventional trials designed to improve the management of EM. Methods We employed a non-invasive method based on the altered burrowing behavior of the animal to predict lesion development in the syngeneic mice EM model. We used the burrowing assay (BA) before dissection as a non-invasive behavioral marker to evaluate lesion progression across three distinct laboratory strains: C57BL/6j, BALB/c, and Swiss albino to account for variation due to genetic, immunological, and strain specificity. Results EM mice displayed a significant decline in burrowing activity compared to controls across all three strains. Based on BA performance, recipient mice were stratified into two groups: Recipients with a low burrow score (LB) and those with a high burrow score (HB). Additionally, LB mice exhibited decreased exploratory behavior and increased sensitivity to thermal pain. In contrast, HB mice had exploratory and thermal responses comparable to those of the control group. Post-dissection, LB mice were presented with ectopic lesions (LB+), whereas HB mice were lesion-negative (HB-). BA performance correlated strongly with lesion presence via ROC analysis, with a combined AUC of 0.883 (and an AUC of 1 for C57BL/6j), indicating excellent diagnostic accuracy of BA in predicting EM incidence. The combined approach of correlating burrowing behavior with other evoked behavioral responses and non-evoked provided a comprehensive assessment of EM disease progression. Conclusion To our knowledge, our research provides evidence for the feasibility of ethologically valid burrowing behaviour as a non-invasive predictor of EM incidence in the syngeneic mice model. Future preclinical drug research for EM management could leverage BA to identify and select only lesion-positive animals for intervention trials. This approach will enhance the translational value of EM research.

Post-partum metritis is among the most prevalent disease in dairy cows affecting animal welfare and inflicting considerable economic loses. While post-partum contamination of the uterus is rife in dairy cows, only a fraction of these animals will develop metritis. Our main objective was to compare the bacterial communities and the inflammatory response in the endometrium of healthy and metritic dairy cows. Holstein–Friesian cows ( n  = 35) were sampled immediately following clinical classification as healthy ( n  = 21), suffering from metritis ( n  = 13) or septic metritis ( n  = 1), based on veterinary examination at 5–10 days post-partum. Polymorphonuclear cells (PMN) percentage in endometrial cytology was significantly higher in cows with metritis. Full-thickness uterine biopsy analysis revealed that the luminal epithelium in inter-caruncle areas was preserved in healthy cows, but in metritis it was compromised, with marked PMN infiltration particularly in the apical endometrium. Gram staining revealed that bacterial load and spatial distribution was associated with disease severity. 16S-rDNA bacterial community analysis revealed unique endometrial bacterial community composition in metritic cows, as compared to more diverse communities among healthy cows. The most abundant phyla in healthy cows were Proteobacteria (31.8 ± 9.3%), Firmicutes (27.9 ± 8.4%) and Bacteroidetes (19.7 ± 7.2%), while Bacteroidetes (60.3 ± 10.3%), Fusobacteria (13.4 ± 5.9%) and Firmicutes (10.5 ± 3.3%) were most abundant in the endometrial mucosa of metritic cows. Relative abundance of Bacteroidetes (19.7 ± 7.2% vs. 60.3 ± 10.3%), Fusobacteria (7.5 ± 5.2% vs. 13.4 ± 5.9%) and Proteobacteria (31.8 ± 9.3% vs. 7.3 ± 5.6%) phyla differed significantly between healthy and metritic cows. In summary, endometrial PMN abundance, spatial distribution and bacterial communities differed between healthy and metritic dairy cows at early post-partum.

In water quality monitoring programs, optimization between information craved and information collected involves scrupulous judgment making processes and management approaches. The present study explores the few essential aspects of water quality monitoring program considering Shannon’s entropy with case studies on a few lakes and wetlands in North Guwahati, Assam (India). Firstly, the loss of information by traditional water quality indices (WQIs) has been addressed by the use of entropy weighted WQIs (EWQIs) which takes into account the randomness of data sets removing error through subjective judgments of experts in assigning parameter weights. This concept was extended to the quantification of heavy metals. The concept of multi-criteria decision-making methods (MCDMs) such as TOPSIS was introduced which utilize entropy weights and rough set theory to give a reliable and unbiased description of overall pollution levels of each sampling location. This study will be of great help to various agencies which take care of the water supply and water pollution control since this forms a significant tool for easy understanding and thereby making their applicability uncomplicated.
