ABSTRACT

The purpose of this study was to determine the effect of lavender oil inhalation on the anxiety and comfort levels of patients scheduled for colonoscopy. Seventy-three experimental group patients scheduled for colonoscopy at a training and research hospital in the west of Turkey in June to September 2022 and 72 control group patients were included in this randomized, controlled, prospective study. Minimal sedation (propofol 2-3 mg/kg) was applied in both groups. Lavender inhalation was applied to the experimental group, whereas the control group patients received nursing care (vital sign monitoring, prevention of complications, and rest). The State-Trait Anxiety Inventory and the Shortened General Comfort Questionnaire were used for pre- and postprocedural data collection. Median ages were 53.00 years (47.25-59.00) in the experimental group patients and 51.00 (44.00-59.5) in the control group. Although postprocedural state anxiety scores were lower in the experimental group compared with the control group, the difference was not statistically significant (p = .069). The general postcolonoscopy comfort score was significantly higher in the experimental group compared with the control group (p < .001). Trait anxiety scores also increased as the number of colonoscopies increased in both groups. We conclude that lavender oil inhalation, a simple and inexpensive intervention, increases patient comfort while exhibiting a positive, albeit statistically insignificant, effect on anxiety.

ABSTRACT

Interactions between stressed organisms and their microbiome environments may provide new routes for understanding and controlling biological systems. However, microbiomes are a form of high-dimensional data, with thousands of taxa present in any given sample, which makes untangling the interaction between an organism and its microbial environment a challenge. Here we apply Latent Dirichlet Allocation (LDA), a technique for language modeling, which decomposes the microbial communities into a set of topics (non-mutually-exclusive sub-communities) that compactly represent the distribution of full communities. LDA provides a lens into the microbiome at broad and fine-grained taxonomic levels, which we show on two datasets. In the first dataset, from the literature, we show how LDA topics succinctly recapitulate many results from a previous study on diseased coral species. We then apply LDA to a new dataset of maize soil microbiomes under drought, and find a large number of significant associations between the microbiome topics and plant traits as well as associations between the microbiome and the experimental factors, e.g. watering level. This yields new information on the plant-microbial interactions in maize and shows that LDA technique is useful for studying the coupling between microbiomes and stressed organisms.

ABSTRACT

INTRODUCTION: Transactional sex is casual sex between two people to receive material incentives in exchange for sexual favors. Transactional sex is associated with negative consequences, which increase the risk of sexually transmitted diseases, including HIV/AIDS, unintended pregnancy, unsafe abortion, and physiological trauma. In Sub-Saharan Africa, several primary studies have been conducted in various countries to examine the prevalence and associated factors of transactional sex among women. These studies had great discrepancies and inconsistent results. Hence, this systematic review and meta-analysis aimed to synthesize the pooled prevalence of the practice of transactional sex among women and its associated factors in Sub-Saharan Africa.

METHOD: Data source: PubMed, Google Scholar, HINARI, the Cochrane Library, and grey literature were searched from March 6 to April 24, 2022, and included studies conducted from 2000 to 2022. The pooled prevalence of transactional sex and associated factors was estimated using Random Effect Model. Stata (version 16.0) was used to analyze the data. The I-squared statistic, a funnel plot, and Egger’s test were used to check for heterogeneity and publication bias, respectively. A subgroup analysis was done based on the study years, source of data, sample sizes, and geographical location.

RESULTS: The pooled prevalence of transactional sex among women in Sub-Saharan Africa was 12.55% (9.59%-15.52%). Early sexual debut (OR = 2.58, 95% CI: 1.56, 4.27), substance abuse (OR = 4.62, 95% CI: 2.62, 8.08), history of sexual experience (OR = 4.87, 95% CI: 2.37, 10.02), physical violence abuse (OR = 6.70, 95% CI: 3.32, 13.53), orphanhood (OR = 2.10, 95% CI: 1.27, 3.47), and sexual violence abuse (OR = 3.76, 95% CI: 1.08, 13.05) were significantly associated with transactional sex.

CONCLUSION: The prevalence of transactional sex among women in sub-Saharan Africa was high. Alcohol consumption, substance abuse, early sex debuts, having a history of sexual experiences, physical violence, and sexual violence increased the practice of transactional sex.

ABSTRACT

In recent years, there has been a strong drive to improve the inclusion of animals of both sexes in the design of in vivo research studies, driven by a need to increase sex representation in fundamental biology and drug development. This has resulted in inclusion mandates by funding bodies and journals, alongside numerous published manuscripts highlighting the issue and providing guidance to scientists. However, progress is slow and barriers to the routine use of both sexes remain. A frequent, major concern is the perceived need for a higher overall sample size to achieve an equivalent level of statistical power, which would result in an increased ethical and resource burden. This perception arises from either the belief that sex inclusion will increase variability in the data (either through a baseline difference or a treatment effect that depends on sex), thus reducing the sensitivity of statistical tests, or from misapprehensions about the correct way to analyse the data, including disaggregation or pooling by sex. Here, we conduct an in-depth examination of the consequences of including both sexes on statistical power. We performed simulations by constructing artificial datasets that encompass a range of outcomes that may occur in studies studying a treatment effect in the context of both sexes. This includes both baseline sex differences and situations in which the size of the treatment effect depends on sex in both the same and opposite directions. The data were then analysed using either a factorial analysis approach, which is appropriate for the design, or a t test approach following pooling or disaggregation of the data, which are common but erroneous strategies. The results demonstrate that there is no loss of power to detect treatment effects when splitting the sample size across sexes in most scenarios, providing that the data are analysed using an appropriate factorial analysis method (e.g., two-way ANOVA). In the rare situations where power is lost, the benefit of understanding the role of sex outweighs the power considerations. Additionally, use of the inappropriate analysis pipelines results in a loss of statistical power. Therefore, we recommend analysing data collected from both sexes using factorial analysis and splitting the sample size across male and female mice as a standard strategy.

ABSTRACT

OBJECTIVE: In order to improve the compatibility of the hospital resource planning (HRP) system for the whole life cycle of medical consumables, and to improve the management and control capabilities of hospital institutions on medical consumables.

METHODS: Based on the traditional HRP system, a secondary development and design of a medical consumables whole life-cycle artificial intelligence module was conducted, and a neural network machine learning algorithm module was introduced to enhance its big data integration and analysis capabilities.

RESULTS: The simulation analysis found that after adding this module, the proportion of minimum inventory, the proportion of procurement cost difference and the expiration rate of consumables all decreased significantly, and the differences were statistically significant (P<0.05).

CONCLUSIONS: The whole life cycle module of medical consumables based on HRP system can effectively improve the management efficiency of hospital medical consumables, adjust the warehouse inventory management ability, and improve the overall management level of medical consumables.

ABSTRACT

PURPOSE: To investigate the effects of different surface treatments and thermocycling on shear bond strength (SBS) be-tween resin cement and zirconia-reinforced lithium-silicate (ZLS) ceramic.

MATERIALS AND METHODS: 96 ZLS ceramic specimens were randomly allocated to four different surface treatment groups: etch and silane (ES), etch and universal primer (EUP), self-etching primer (SEP), and sandblasting and silane (SS). Stan-dardized composite cylinders were bonded to surface-treated ZLS ceramic, after which SBS was obtained either after 24-h water storage only or with an additional 5000 thermal cycles (TC), resulting in eight subgroups (n = 12). After evaluation of failure mode under a stereomicroscope, representative SEM images were acquired. To examine areal average surface roughness (Sa), additional ZLS specimens were prepared and randomly allocated to 3 groups: hydrofluoric acid etching, self-etching primer, and sandblasting (n = 10). Supplementary specimens were examined using field-emission scanning electron microscopy (FE-SEM) (n = 2) and atomic force microscopy (AFM) (n = 2) to investigate their surface topographies.

RESULTS: ANOVA showed a statistically significant difference in SBS following different surface treatment protocols after 24-h water storage (p < 0.001). However, TC groups revealed no statistically significant difference in their SBS (p = 0.394). All surface treated groups were significantly affected by TC (p < 0.001), except for the SS group (p = 0.48). Sa was signifi-cantly influenced by the different surface treatment protocols (p < 0.001).

CONCLUSION: The ability of self-etching primer to achieve comparable bond strength with a less technique-sensitive ap-proach makes it a favorable alternative to ES for the surface treatment of ZLS ceramics.

ABSTRACT

OBJECTIVE: We systematically assessed all available evidence on the efficacy and safety of sacral neuromodulation (SNM) in pregnancy.

METHODS: On September 2022, a thorough search was done on Ovid, PubMed, Scopus, ProQuest, Web of Science, and The Cochrane Library. We chose studies that included pregnant women who had SNM previously. Two authors independently evaluated the quality of the study using a standardized tool of JBI. Studies were given a risk of bias rating of low, moderate, or high. Given the descriptive nature of this study, we utilized descriptive statistics to report demographic and clinical features. For continuous variables, we used mean and standard deviation, and for dichotomous data, we used frequencies and percentages.

RESULTS: Out of 991 abstracts screened, only 14 studies met our inclusion criteria and were included in the review. Overall, the quality of the evidence available from the literature is low based on the design of the included studies. Fifty-eight women, including 72 pregnancies, had SNM. The indication of SNM implantation was filling phase disorders in 18 cases (30.5%), voiding dysfunction in 35 women (59.3%), IC/BPS in two cases (3.5%), and fecal incontinence. In 38 pregnancies (58.5%), the SNM status was ON during pregnancy. Forty-nine cases delivered a full-term baby (75.4%), 12 cases had pre-term labor (18.5%), two miscarriages, and two postterm pregnancies happened. The most complications in patients with devices were urinary tract infection in 15 women (23.8%), urinary retention in six patients (9.5%), and pyelonephritis in two cases (3.2%). The findings revealed that when the device was deactivated, 11 cases out of the 23 patients (47.8%) had full-term pregnancies, while in ON status, 35 out of the 38 pregnant women (92.1%) had full-term pregnancies. Nine preterm labors in OFF (39.1%), and two in ON status (5.3%) were recorded. The results revealed that this difference was statistically significant (p = 0.002), and those who turned SNM of them off had more preterm labor. Although the studies reported all neonates had a healthy status, two children had chronic motor tic problems and a pilonidal sinus in a case with an active SNM in pregnancy. However, there was no association between the SNM status and pregnancy or neonatal complications (p = 0.057).

CONCLUSION: SNM activation in pregnancy seems safe and effective. The choice of whether to activate or deactivate SNM should be made on an individual basis given the current SNM evidence.

ABSTRACT

BACKGROUND: Cholecystectomy, hepatectomy, and lymphadenectomy are recommended as the curative treatment for resectable gallbladder cancer (GBC). Textbook outcomes in liver surgery (TOLS) is a novel composite measure that has been defined by expert consensus to represent the optimal postoperative course after hepatectomy. This study aimed to determine the incidence of TOLS and the independent predictors associated with TOLS after curative-intent resection in GBC patients.

METHODS: All consecutive GBC patients who underwent curative-intent resection between 2014 and 2020 were enrolled from a multicenter database from 11 hospitals as the training and the internal testing cohorts, and Southwest Hospital as the external testing cohort. TOLS was defined as no intraoperative grade greater than or equal to 2 incidents, no grade B/C postoperative bile leaks, no postoperative grade B/C liver failure, no 90-day postoperative major morbidity, no 90-day readmission, no 90-day mortality after hospital discharge, and R0 resection. Independent predictors of TOLS were identified using logistic regression and were used to construct the nomogram. The predictive performance was assessed using the area under the curve and calibration curves.

RESULTS: TOLS was achieved in 168 patients (54.4%) and 74 patients (57.8%) from the training and internal testing cohorts, and the external testing cohort, respectively. On multivariate analyses, age less than or equal to 70 years, absence of preoperative jaundice (total bilirubin≤3 mg/dl), T1 stage, N0 stage, wedge hepatectomy, and no neoadjuvant therapy were independently associated with TOLS. The nomogram that incorporated these predictors demonstrated excellent calibration and good performance in both the training and external testing cohorts (area under the curve: 0.741 and 0.726).

CONCLUSIONS: TOLS was only achieved in approximately half of GBC patients treated with curative-intent resection, and the constructed nomogram predicted TOLS accurately.

ABSTRACT

BACKGROUND: Multiple scores have been created in order to predict difficult cholecystectomy, nonetheless there is not a consensuated standard on which to use. The importance of a predictive score to be able to establish a difficult cholecystectomy would be a relevant instrument in order to better inform the patient, properly call for help when needed, choose the correct staff, and schedule and plan the surgical procedure accordingly.

METHODS: A diagnostic trial study was performed. All different predictive scores for difficult cholecystectomy were calculated for each patient. The correlation between the preoperative score and cholecystectomies considered as “difficult” were measured estimating the preoperative score’s predictive value using a ROC curve in order to predict findings for difficult cholecystectomy.

RESULTS: A total of 635 patients between 2014-2021 were selected. Selected patients had a mean age of 55.0 (IQR: 28.00) and were mostly female (64.25%). Surgical outcomes of patients with difficult cholecystectomy had statistically significant higher rates of subtotal cholecystectomies, drain usage, complications and reinterventions, prolonged surgical times, and longer hospital stay. When analyzing the predictive value on each of the different scores applied, score 4 had the highest performance for predicting difficult cholecystectomy with an AUC=0.783 (CI 95% 0.745-0.822).

CONCLUSIONS: Difficult cholecystectomies are associated with worse surgical outcomes. The standardization and use of predictive scores for difficult cholecystectomy must be implemented in order to improve surgical outcomes as a result of more meticulous planning when scheduling the procedure.

ABSTRACT

Aim: To evaluate the clinical performance of PAX1 methylation (PAX1^m) and cytology for patients with non-HPV16/18 high-risk HPV (hrHPV) infection. Methods: Cervical exfoliated cells from 387 outpatients with non-HPV16/18 hrHPV – positive were collected for cytology and PAX1^m assays. Results: The PAX1^m level increased with the severity of cytology and histopathology. For cervical intraepithelial neoplasia (CIN)CIN2+/CIN3+, the areas under the curve were both 0.87. The specificity and positive predictive value (PPV) of PAX1^m were greater than abnormal cytology (CIN2+ specificity: 75.5 vs 24.8%; PPV: 38.8 vs 18.7%; CIN3+ specificity: 69.3 vs 22.7%; PPV: 14.0 vs 6.7%). Conclusion: PAX1^m increased specificity and PPV for CIN2+/CIN3+ compared with cytology for women with non-HPV16/18 hrHPV (+).
