Differential Composition and Structure of the Microbiota from Active and Inactive Stages of HLA-B27-associated Uveitis by Paired Fecal Metagenomes

ABSTRACT Purpose To compare the diversities and abundances of bacterial taxa in the microbiome of patients with HLA B27-positive acute anterior uveitis (AAU) in the active and inactive phases. Methods An observational descriptive prospective and comparative study was conducted in ten HLA-B27-positive AAU patients (44.6 ± 13.4 years). The microbiome of the stool samples obtained in the active and inactive stages was analyzed by sequencing the V3 region of the 16S rRNA gene. Results The differences in the bacteria profile between active and inactive stages in each individual were confirmed (p < 0.0001). Ten OTUs were found exclusively in the active phase of 90% of the individuals, suggesting a proinflammatory association. Blautia OUT_4 and Faecalibacterium OUT_2 abundances showed a direct relationship between abundance and severity of ocular inflammation. Two OTUs were exclusive of the inactive stage, suggesting an anti-inflammatory role. Conclusion The metagenomic profile of the fecal microbiota differs in the acute phase of the AAU compared to when the inflammation subsides, despite being the same individual and a short time-lapse. AAU is a fertile field for studying the connection between subtle rapid changes in microbiota and their systemic consequences.

Risk of Ischemic Stroke in Relation to Helicobacter pylori Infection and Eradication Status: A Large-Scale Prospective Observational Cohort Study.

: A few studies have suggested the association between Helicobacter pylori (HP) infection and ischemic stroke. However, the impact of HP eradication on stroke risk has not been well evaluated. This study aimed to assess the influence of HP eradication on the incidence of ischemic stroke, considering the potential effect of sex. : This prospective observational cohort study was conducted at Seoul National University Bundang Hospital, from May 2003 to February 2023, and involved gastroscopy-based HP testing. Propensity score (PS) matching was employed to ensure balanced groups by matching patients in the HP eradicated group (n=2,803) in a 3:1 ratio with patients in the HP non-eradicated group (n=960). Cox proportional hazard regression analysis was used to evaluate the risk of ischemic stroke. : Among 6,664 patients, multivariate analysis after PS matching indicated that HP eradication did not significantly alter the risk of ischemic stroke (hazard ratio, 0.531; 95% confidence interval, 0.221 to 1.270; p=0.157). Sex-specific subgroup analyses, both univariate and multivariate, did not yield statistically significant differences. However, Kaplan-Meier analysis revealed a potential trend: the females in the HP eradicated group exhibited a lower incidence of ischemic stroke than those in the HP non-eradicated group, although this did not reach statistical significance (p=0.057). : This finding suggests that HP eradication might not impact the risk of ischemic stroke. However, there was a trend showing that females potentially had a lower risk of ischemic stroke following HP eradication, though further investigation is required to establish definitive evidence.

BackgroundThere is a lack of individualised prediction models for patients hospitalised with chronic obstructive pulmonary disease (COPD) for clinical practice. We developed and validated prediction models of severe exacerbations and...

Thrombocytopenia risks in ARDS COVID-19 patients treated with high-dose linezolid during vvECMO therapy: an observational study.

Patients treated with ECMO are at great risk of nosocomial infections, and around 10% of isolates are gram-positive pathogens. Linezolid (LZD) is effective in the treatment of these infections but appropriate dosing is challenging. The aim was to evaluate the occurrence of thrombocytopenia during ECMO when treated with LZD. An LZD trough concentration of 8mg/L was set as the cutoff value for thrombocytopenia occurrence among critically ill patients who received parenteral LZD therapy at a dose of 600mg every 8h during ECMO. Eleven patients were included in this prospective observational study. Median LZD trough concentrations were 7.85 (interquartile range (IQR), 1.95-11) mg/L. Thrombocytopenia was found in 81.8% of patients. Based on the median LZD trough concentrations cutoff value, patients were divided into two groups, 1.95 (IQR, 0.91-3.6) and 10.3 (IQR, 9.7-11.7) mg/L, respectively. Median platelet values differed significantly between groups on admission, ECMO day 0, ECMO day 1, and LZD sampling day [194 and 152.5, (p < 0.05)], [113 and 214, (p < 0.05)], [76 and 147.5, (p < 0.01)], and [26 and 96.5, (p < 0.01)], respectively. Duration of LZD therapy was similar between the groups. Significant platelet reduction was observed in both groups, emphasizing the need for closer monitoring to prevent LZD-associated thrombocytopenia.

Transanal eco-Doppler evaluation after hemorrhoidal artery embolization

BACKGROUND Hemorrhoidal artery embolization (Emborrhoid) is a novel method for the treatment of severe hemorrhoidal bleeding. Despite having a technical success rate of 93%-100%, the clinical success ranges between 63% and 94%, with a rebleeding rate of 13.6%. AIM To evaluate the effectiveness of this procedure in reducing hemorrhoidal flow and hemorrhoidal bleeding. METHODS This prospective observational pilot study was conducted at Division of General Surgery 1 and Tertiary Referral Pelvic Floor Center, Treviso Regional Hospital, Italy. In a 2 months period (February-March 2022), consecutive patients with hemorrhoidal bleeding scores (HBSs) ≥ 4, Goligher scores of II or III, failure of non-operative management, and a candidate for Emborrhoid were included. Endoanal ultrasound with eco-Doppler was performed preoperatively and 1 month after the procedure. The primary endpoint was to quantify the changes in arterial hemorrhoidal flow after treatment. The secondary endpoint was to evaluate the correlation between the flow changes and the HBS. RESULTS Eleven patients underwent Emborrhoid. The overall pretreatment mean systolic peak (MSP) was 14.66 cm/s. The highest MSP values were found in the anterior left lateral (17.82 cm/s at 1 o’clock and 15.88 cm/s at 3 o’clock) and in the posterior right lateral (14.62 cm/s at 7 o’clock and 16.71 cm/s at 9 o’clock) quadrants of the anal canal. After treatment, the overall MSP values were significantly reduced (P = 0.008) although the correlation between MSP and HBS changes was weak (P = 0.570). A statistical difference was found between distal embolization compared with proximal embolization (P = 0.047). However, the coil landing zone was not related to symptoms improvement (P = 1.000). A significant difference in MSP changes was also reported between patients with type 1 and type 2 superior rectal artery (SRA) anatomy (P = 0.040). No relationship between hemorrhoidal grades (P = 1.000), SRA anatomy (P = 1.000) and treatment outcomes was found. CONCLUSION The preliminary findings of this pilot study confirm that Emborrhoid was effective in reducing the arterial hemorrhoidal flow in hemorrhoidal disease. However, the correlation between the post-operative MSP and HBS changes was weak. Hemorrhoidal grade, SRA anatomy and type of embolization were not related to treatment outcomes.

Operating Room Waste Generated From Corneal and Conjunctival Surgeries.

The purposes of this study were to bring awareness to the surgical waste generated from corneal and conjunctival surgeries and to compare those findings with the waste generated from cataract surgeries. This was an observational prospective pilot cohort study at a tertiary corneal/anterior segment private practice. All waste related to cataract, cornea, and conjunctival surgical procedures (including anesthesia waste and corneal tissue storage) was weighed. The primary outcome was total waste generated while other outcomes included surgical setting (ambulatory surgical center, hospital, and minor operating room) and comparison of corneal/conjunctival surgeries with cataract surgery. Surgical waste data were collected from 119 surgeries (82 corneal/conjunctival surgeries and 37 cataract surgeries). Hospital surgeries produced more waste than ambulatory surgical center and minor operating room surgeries. Penetrating keratoplasty (2.22 kg, P = 0.483) and Descemet stripping only (2.11 kg, P = 0.326) procedures generated comparable mean waste with cataract surgery (2.07 kg) while endothelial keratoplasties produced more (P < 0.001, 0.002). (Deep) anterior lamellar keratoplasty results depended on the surgical setting. All conjunctival surgeries produced less waste than cataract surgery. In comparison with cataract surgery, keratoplasties overall produced comparable or more waste while conjunctival surgeries produced less waste. The surgical setting and type of anesthesia played a substantial role in the amount of waste generated. Assessing waste production from different ophthalmic surgeries may increase awareness of the negative environmental impact of surgical waste and promote practice or legal changes to improve environmental sustainability.

Accelerometer-based sedentary time and physical activity from childhood through young adulthood with progressive cardiac changes: a 13-year longitudinal study.

Longitudinal evidence on the relationship of sedentary time (ST), light-intensity physical activity (LPA), and moderate-to-vigorous-intensity physical activity (MVPA) with changes in cardiac structure and function in the paediatric population is scarce. This evidence is clinically important due to the impact ST can have on the long-term prognosis of healthy young population in the lifetime continuum. This prospective observational study examined the relationships of cumulative ST, LPA, and MVPA from childhood with longitudinal changes in cardiac structure and function. This is a secondary analysis from the Avon Longitudinal Study of Parents and Children, UK birth cohort of 1682 children aged 11 years. Participants who had at least one follow-up timepoints accelerometer-measured ST, LPA, and MVPA over a period of 13 years and repeated echocardiography-measured cardiac structure and function at ages 17- and 24-year clinic visit were included. Left ventricular mass indexed for height2.7 (LVMI2.7) and left ventricular (LV) diastolic function from mitral E/A ratio (LVDF) were computed. Among 1682 children (mean [SD] age, 11.75 [0.24] years; 1054 [62.7%] females), the cumulative one-min/day increase in ST from ages 11 to 24 years was associated with progressively increased LVMI2.7 {effect estimate 0.002 g/m2.7 [confidence interval (CI) 0.001-0.003], P < 0.001}, irrespective of sex, obesity, and hypertensive status. Cumulative one-min/day increase in LPA was associated with a decreased LVMI2.7 (-0.005 g/m2.7 [-0.006 to -0.003], P < 0.0001) but an increased LVDF. Cumulative one-minute/day increase in MVPA was associated with progressively increased LVMI2.7 (0.003 g/m2.7 [0.001-0.006], P = 0.015). ST contributed +40% to the 7-year increase in cardiac mass, MVPA increased cardiac mass by +5%, but LPA reduced cardiac mass by -49%. Increased ST may have long-term pathologic effects on cardiac structure and function during growth from childhood through young adulthood; however, engaging in LPA may enhance cardiac health in the young population.

Echocardiographic assessment of right ventricular performance in COVID-19 related acute respiratory distress syndrome: the importance of systo-diastolic interaction.

The cardiac manifestations of COVID-19 have been described in patients with acute respiratory distress syndrome (ARDS) admitted to intensive care unit (ICU). The presence and impact of right ventricular (RV) diastolic function and performance has not been studied in this population yet. We describe the prevalence of RV diastolic dysfunction, assessed by the pulmonary valve pre-ejection A wave (PV A wave), and the RV systo-diastolic interaction, using the RV total isovolumic time (t-IVT), in COVID-19 ARDS. Prospective observational study enrolling patients with moderate to severe COVID-19 ARDS admitted to ICU who underwent a transthoracic echocardiogram within 24h of ICU admission and at least a second one during the ICU stay. Respiratory, hemodynamic and biochemistry parameters were collected. 163 patients (age 61.0 ± 9.3years, 72% males) were enrolled. 36 patients (22.1%) had RV dysfunction, 45 (27.1%) LV systolic dysfunction. 73 patients (44.7%) had PV A wave. The RV t-IVT correlated with TAPSE at ICU admission (p < 0.002; r -0.61), presence of PV A wave (p < 0.001; r 0.78), peak inspiratory pressure (PIP) (p < 0.001; r 0.42), PEEP (p < 0.001; r 0.68), dynamic driving pressure (DDP) (p < 0.001; r 0.58), and PaO2/FiO2 ratio (p < 0.01; r -0.35). The presence of PV A wave was associated with higher PIP (p < 0.001; r 0.45), higher PEEP (p < 0.001; r 0.56), higher DDP (p < 0.01, r 0.51), and lower PaO2/FiO2 ratio (p < 0.001; r -0.49). RV t-IVT and the presence of PV A wave are non-invasive means to describe a significant RV diastolic dysfunction and may be consider descriptive signs of RV performance in COVID-19 ARDS.

Ocular surface complications in children undergoing general anaesthesia: A prospective observational study.

Ophthalmic complications frequently occur after procedures requiring general anaesthesia, but their incidence is widely variable and not well reported in the paediatric population. The aim was to identify the incidence and possible risk factors of postoperative ocular surface complications in a tertiary care centre. This is a prospective study for paediatric patients undergoing general anaesthesia. An ophthalmologist performed the ocular examination after surgery. Parameters assessed were tear breakup time, punctate epithelial erosions and corneal abrasions. Multivariate logistic regression model was used to assess risk factors. A total of 108 paediatric patients were recruited, 36.1% showed abnormal corneal finding: 32 (29.6%) had decreased tear breakup time, three (2.7%) had punctate epithelial erosions, three (2.7%) had both punctate epithelial erosions and decreased tear breakup time and one (0.9%) was found to have a unilateral corneal abrasion postoperatively. A higher rate of corneal complications was noted with younger age, prolonged surgery and surgery in the head and neck region. The rate of postoperative corneal abnormalities in children undergoing general anaesthesia was 36.1%, associated with younger age, prolonged surgery and surgery in the head and neck region.

Influence of the External Workload on Calf Muscle Strain Injuries in Professional Football Players: A Pilot Study.

The influence of external workload variables on the development of calf muscle strainsin football players has not been previously explored. Overloaded players would have an increased risk of calf muscle strain injury. Prospective observational study. Level 4. A total of 41 professional football players from 1 team were monitored for 2 consecutive seasons. Total distance covered (TD), and distances covered at high-intensity running, high sprint running, low (LACC) and high (HACC) acceleration, low (LDEC) and high (HDEC) deceleration, and at high metabolic load distance (HMLD) were monitored with GPS units. Accumulated players' external workload in the week before injury was compared with the weekly mean value of the 6 weeks before injury occurred for each player. Ten players (24.3%) suffered 16 calf muscle strain injuries (3.1 injuries per 1000 hours of match play; 0.5 injuries per 1000 hours of training exposure). Players with a calf muscle injury were older (p = 0.03), with higher body weight (p = 0.01) and height (p = 0.03). Injured players displayed substantially higher total training volume (p < 0.01), TD (p < 0.01), LACC (p < 0.01), LDEC (p < 0.01), HACC (p < 0.01), HDEC (p < 0.01), and HMLD (p = 0.03) in the week before injury, in comparison with the mean values of these variables in the 6 weeks before injury. A week with a higher-than-habitual external workload might increase the risk of calf muscle strain injury in professional football players. Calf muscle injuries were preceded by a week with unusually high workloads associated with accelerating and decelerating distances and higher training volumes. Monitoring external workload indicators may be helpful in determine players with a higher risk of calf muscle strain injury due to excessive workload during training/competition.

Sonographic assessment of the diaphragm in COVID 19 and non-COVID ICU patients

BackgroundSonographic evaluation of the diaphragm has gained popularity in the ICU due to the necessity of assessing diaphragmatic function in a variety of clinical situations. The sonographic examination of diaphragmatic dynamics in ICU patients by measuring diaphragmatic thickness and excursion in connection to various modalities of mechanical ventilation (MV) and patient outcomes was the objective of this study.MethodsThis prospective observational study was carried out on 50 patients in respiratory ICU in Kafr Elsheikh and Benha University Hospitals. Patients were classified into 2 equal groups: COVID-19 group and non-COVID group. All patients underwent ultrasound assessment included the diaphragm thickness fraction and excursion in ICU patients on admission and on weaning.ResultsSuccessful weaning (SW) was higher in group I compared to group II. In group I (COVID), diaphragm excursion, thickness at end inspiration and at end expiration in NIV at weaning were significantly higher in patients with SW but thickness at end expiration on admission was significantly lower. In group II (non-COVID) MV patients, excursion at weaning was significantly higher in patients with SW, also were thickness at end inspiration and end expiration on admission, thickness at end inspiration and end expiration at weaning in NIV patients but thickness at end inspiration in MV on admission was significantly lower.ConclusionWeaning success and mortality were significantly predicted by excursion in NIV at weaning, thickness at end inspiration in MV at weaning, thickness at end inspiration in NIV at weaning, and thickness at end expiration in MV at weaning.

Maternal vascular indices at 36 weeks' gestation in small and growth restricted fetuses.

To compare maternal vascular indices and hemodynamic parameters at 35-37 weeks' gestation, in pregnancies complicated by small for gestational age (SGA) fetuses and those with fetal growth restriction (FGR). This was a prospective observational non-intervention study in women with singleton pregnancies attending for a routine hospital visit at 35+0 to 36+6 weeks' gestation. The visit included recording of maternal demographic characteristics and medical history, vascular indices and hemodynamic parameters obtained by a non-invasive operator independent device, including pulse wave velocity, augmention index, cardiac output, stroke volume, central systolic and diastolic blood pressure, total peripheral resistance and fetal heart rate. Hypertensive disorders of pregnancy were excluded and the values in the SGA and FGR groups were compared between them and with unaffected pregnancies. Diagnosis of SGA was based on the birth of a baby with birthweight below the 10th percentile for gestational age. In FGR, in addition to a birthweight below the 10th percentile, at the 35-37 weeks scan Doppler studies had shown that the uterine artery or umbilical artery pulsatility index (PI) was above the 95th percentile for gestational age or the fetal middle cerebral artery PI was below the 5th percentile. In the 6,413 women included in the study there were 605 (9.4%) cases of SGA, 133 (2.1%) of FGR and 5,675 (88.5%) unaffected by SGA or FGR. Women with SGA or FGR, compared to unaffected pregnancies, had increased peripheral vascular resistance and reduced cardiac output. Central systolic and diastolic blood pressure were also increased, whereas aortic stiffness assessed by pulse wave velocity and augmentation index did not differ between affected and unaffected pregnancies. In the FGR, compared to the SGA group, central systolic and diastolic blood pressure were higher, whereas, heart rate was lower. In SGA and FGR pregnancies there are deranged maternal hemodynamic responses when these are compared to normal pregnancies. Mothers with FGR babies have higher central blood pressure compared to SGA ones, but it remains unclear whether these differences are driven by the size of the fetus or pathological fetal growth.

A first trimester prediction model and nomogram for gestational diabetes mellitus based on maternal clinical risk factors in a resource-poor setting

BackgroundThe implementation of universal screening for Gestational Diabetes Mellitus (GDM) is challenged by several factors key amongst which is limited resources, hence the continued reliance on risk factor-based screening. Effective identification of high-risk women early in pregnancy may enable preventive intervention. This study aimed at developing a GDM prediction model based on maternal clinical risk factors that are easily assessable in the first trimester of pregnancy in a population of Nigerian women.MethodsThis was a multi-hospital prospective observational cohort study of 253 consecutively selected pregnant women from which maternal clinical data was collected at 8–12 weeks gestational age. Diagnosis of GDM was made via a one-step 75-gram Oral Glucose Tolerance Test (OGTT) at 24–28 weeks of gestation. A GDM prediction model and nomogram based on selected maternal clinical risk factors was developed using multiple logistic regression analysis, and its performance was assessed by Receiver Operator Curve (ROC) analysis. Data analysis was carried out using Statistical Package for Social Sciences (SPSS) version 25 and Python programming language (version 3.0).ResultsIncreasing maternal age, higher body mass index (BMI), a family history of diabetes mellitus in first-degree relative and previous history of foetal macrosomia were the major predictors of GDM. The model equation was: LogitP = 6.358 − 0.066 × Age − 0.075 × First trimester BMI − 1.879 × First-degree relative with diabetes mellitus − 0.522 × History of foetal macrosomia. It had an area under the receiver operator characteristic (ROC) curve (AUC) of 0.814 (95% CI: 0.751–0.877; p-value < 0.001), and at a predicted probability threshold of 0.745, it had a sensitivity of 79.2% and specificity of 74.5%.ConclusionThis first trimester prediction model reliably identifies women at high risk for GDM development in the first trimester, and the nomogram enhances its practical applicability, contributing to improved clinical outcomes in the study population.

A Transfusion Regimen With Same-donor Packed Red Blood Cells Reduces Exposure to Multiple Blood Donors in Craniosynostosis Surgery.

In major craniosynostosis surgery with moderate to severe blood loss, patients may be exposed to multiple donors. We have previously reported a method for reducing donor exposure using mixed pediatric units including plasma. To further reduce donor exposure, we used plasma-free divided pediatric units. The study aimed to investigate the feasibility of the new strategy for reducing donor exposure. This prospective observational study recruited children younger than 1 year who were scheduled for nonsyndromic craniosynostosis surgery. One adult red blood cell unit was divided into 4 equal units on the day before the operation for use intra- or postoperatively. Number of donor exposures, estimated blood loss, crystalloid, colloid, and blood product volumes, and coagulation parameters were evaluated. Nineteen infants were included. The mean estimated blood loss was 19 (3) mL/kg and the transfusion volume was 17 (7) mL/kg. The median donor exposure per patient was 1 (range, 1-3). During surgery, all infants received at least one DPU. Two infants received transfusions from more than one donor during the intraoperative period. In the first 24 hours postoperatively, 14 infants received transfusion; 10 received only DPUs, whereas 4 received from multiple donors. In all, multiple donor exposure was prevented in 14 of 19 infants. Postoperative Pk-INR was 1.33 (0.16); no plasma or platelets were transfused. The plasma-free DPU transfusion protocol may be useful to reduce donor exposure in open craniosynostosis surgery in infants.

Pain Management and Sociology Implications: The Sociomedical Problem of Pain Clinic Staff Harassment Caused by Chronic Pain Patients

Background: Patients with chronic pain often experience psychological issues. They may also exhibit harassing behaviors toward healthcare staff. This complex sociomedical issue necessitates increased attention. Objectives: This study analyzed incidents of staff harassment caused by chronic pain patients. It examined the characteristics of chronic pain patients who harassed clinic staff, as well as the causative or associated factors. The study also explored the management and outcomes of these harassment incidents. Methods: This prospective observational study involved 1102 chronic pain patients who received treatment at a pain clinic. Data were prospectively collected on patients' gender, age, ethnicity, occupation, injury insurance claims, and incidents of staff harassment caused by patients. Results: Pain clinic staff were harassed by 121 patients (11 %). Among the harassers, females constituted 70.2 % and males 29.8 %. Additionally, 50.4 % of the harassers were unemployed, with unemployed patients causing more staff harassments (P = 0.001). A significant portion, 86 %, of the harassers had injury insurance claims and were associated with a higher incidence of staff harassments (P = 0.002). Patients making disability insurance claims also caused more staff harassments (P = 0.001). Among the harassers, 50.4 % demanded higher drug doses, and 50 % did not have regular primary healthcare providers. The types of harassment included insults (34.7 %), threats (19.8 %), retaliations (3.3 %), and sexual harassment (42.2 %). All cases of sexual harassment were addressed; the patients involved were counseled. Most harassment incidents were resolved through tactful communication. Of the harassers, 9.9 % were discharged from the clinic. Conclusions: Harassment of pain clinic staff by chronic pain patients is significant. This sociomedical issue may be worsening due to factors such as opioid misuse, racism, the pandemic, and socioeconomic challenges. While most chronic pain patients are reasonable, some can be challenging. This study confirmed that the majority of patients who harassed staff were female, unemployed, had made injury insurance claims, and demanded higher drug doses. Abusive patients should receive anxiolytic therapy, behavioral boundaries, counseling, distraction therapy, and empathy. Pain clinics should implement staff training and support programs to protect staff from harassment. Additionally, pain clinicians should establish peer support networks to mitigate the psychological impacts of patient aggression and maintain professional well-being.

Oral health-related quality of life in implant-supported rehabilitations: a prospective single-center observational cohort study

BackgroundOral Health-Related Quality of Life (OHRQoL) is a comprehensive concept covering daily comfort, self-esteem, and satisfaction with oral health, including functional, psychological, and social aspects, as well as pain experiences. Despite abundant research on OHRQoL related to oral diseases and hygiene, there is limited data on how patients perceive changes after implant-prosthetic rehabilitation. This study aimed to evaluate OHRQoL and aesthetic perception using OHIP-14 and VAS scales respectively, before (baseline-TB), during (provisional prostheses-TP), and after (definitive prostheses-TD) implant-prosthetic rehabilitation. It also explored the impact of biological sex, substitution numbers, and aesthetic interventions on OHRQoL and VAS scores, along with changes in OHIP-14 domains.MethodsA longitudinal prospective single-center observational cohort study was conducted with patients requiring implant-prosthetic rehabilitation. Quality of life relating to dental implants was assessed through the Italian version of Oral Health Impact Profile-14 (IOHIP-14), which has a summary score from 14 to 70. Patients’ perceived aesthetic was analyzed through a VAS scale from 0 to 100. Generalized Linear Mixed Effect Models, Linear Mixed Effect Models, and Friedman test analyzed patient responses.Results99 patients (35 males, 64 females) aged 61–74, receiving various prosthetic interventions, were enrolled. Both provisional and definitive prosthetic interventions significantly decreased the odds of a worse quality of life compared to baseline, with odds ratios of 0.04 and 0.01 respectively. VAS scores increased significantly after both interventions, with estimated increases of 30.44 and 51.97 points respectively. Patient-level variability was notable, with an Intraclass Correlation Coefficient (ICC) of 0.43. While biological sex, substitution numbers, and aesthetic interventions didn’t significantly affect VAS scores, OHRQoL domains showed significant changes post-intervention.ConclusionsThese findings support the effectiveness of implant-prosthetic interventions in improving the quality of life and perceived aesthetics of patients undergoing oral rehabilitation. They have important implications for clinical practice, highlighting the importance of individualized treatment approaches to optimize patient outcomes and satisfaction in oral health care.

Pediatric arterial ischemic stroke; Risk factors, clinical presentation and short-term outcome of patients presenting at a tertiary care hospital.

Objective: To determine the risk factors, clinical presentation and short term outcome in children presenting with arterial ischemic stroke at a tertiary care hospital. Study Design: Prospective Observational study. Setting: Medical Units of National Institute of Child Health, Karachi, Pakistan. Period: November 2022 October 2023. Methods: Children of either gender aged between 1 month to 12 years and admitted with the diagnosis of pediatric arterial ischemic stroke during the study duration were analyzed. Detailed medical and neurological examinations were performed. Routine work up and laboratory investigations were done. Modified Rankin Scale (MRS) scores at the time of enrollment, discharge and after 3 month follow-up were recorded. Results: In a total of 35 children, 21 (60.0%) were boys the mean age was 6.89±3.63 years. The most frequent presenting clinical features were focal neurological deficits noted in 29 (82.9%) children whereas fever, and fits were reported in 26 (74.3%), and 22 (62.9%) children, respectively. Right hemiplegia was observed in 15 (42.9%) children. Stroke was secondary to moyamoya 8 (22.9%), infections in 6 (17.1%) children. Mortality was reported among 3 (8.6%) children while 3 others lost during the follow ups. Comparison of mean mRS scores at the time of admission, discharge and after 3 months showed significant reduction (p&lt;0.001). Conclusion: Focal neurological deficits were the predominant clinical features, with a significant incidence of associated fever and seizures. Moyamoya and infections emerged as primary causative factors. Despite a mortality rate of 8.6%, there was an overall improvement in outcomes, as evidenced by a significant reduction in Modified Rankin Scale scores at admission, discharge, and after three months.

Prospective observational study comparing the perioperative outcomes of laparoscopic colectomy with or without epidural anesthesia: the Kanagawa Yokohama Colorectal Cancer Study Group (KYCC) 1806.

There have been no adequate comparisons of the efficacy, safety, and efficiency of analgesia after laparoscopic colorectal resection (LAC), with and without epidural anesthesia (EDA). This was a multicenter prospective observational study of patients undergoing LAC. The primary end point was the mean visual analog scale (VAS) score on postoperative days (PODs) 1-7. The secondary end points were the highest VAS, complication rate, days to first ambulation and fatigue, length of hospital stay, and time to commencement of surgery. We compared an EDA group (Group E, n = 48) and a no-EDA group (Group O, n = 48) after matching. The mean VAS was not significantly different between the groups (28.7 vs. 30.1, p = 0.288). On assessing the secondary end points, the highest VAS was not significantly different between the groups. In fact, the VAS was lower in Group E only on POD 2. There was no difference in the incidence of complications, the time to first postoperative evacuation was shorter in Group E, and postoperative hospitalization was similar. The time to surgery was shorter in Group O. These results suggest that LAC without EDA is a feasible option, but with the early and regular use of adjunctive measures to provide more stable analgesia.

Risk of gestational diabetes in women with PCOS based on body mass index: The Japan Environment and Children's Study.

Women with polycystic ovary syndrome (PCOS), which is the most common endocrine disorder in women of reproductive age, have a potentially increased risk of gestational diabetes mellitus (GDM). To examine the impact of PCOS on GDM based on maternal body mass index (BMI) using data from a large birth cohort study in Japan. Prospective observational study using data from the Japan Environment and Children's Study (JECS). Singleton pregnancies in the JECS during 2011-2014 were included. Mothers with HbA1c levels of ≥6.5% in the first trimester and history of DM or steroid use during pregnancy were excluded. Participants were categorized according to their pre-pregnancy BMIs: G1 (<18.5 kg/m2), G2 (18.5-19.99 kg/m2), G3 (20.0-22.99 kg/m2), G4 (23.0-24.99 kg/m2), and G5 (≥25.0 kg/m2). The impact of PCOS on early (Ed) and late-onset (Ld) GDM for each group was estimated using a multiple logistic regression model. We included 92774 participants, comprising 2012 PCOS(+) cases. GDM occurrence was higher in women with PCOS (p<0.001). PCOS had no effect on GDM in G1, G2, and G3. In G4, PCOS increased the risk of Ed GDM (adjusted odds ratio [aOR]: 3.27, 95% confidence interval [CI]: 1.29-8.29). In G5, PCOS increased the risk of both Ed (aOR: 2.48, 95% CI: 1.53-4.02) and Ld GDM (aOR: 1.94, 95% CI: 1.23-3.07). The impact of PCOS on GDM occurrence depended on the pre-pregnancy BMIs, which may facilitate personalized preconception counseling among women with PCOS.
