Background: Indwelling bladder catheters are routinely used in clinical practice. Patients may experience postoperative indwelling catheter-related bladder discomfort (CRBD). This study aimed to perform a literature review to identify predictors of postoperative CRBD.

Methods: We searched PubMed for relevant articles published between 2000 and 2020 using the search items "CRBD", "catheter-related bladder discomfort", and "prediction". Additionally, we searched for articles that matched the research objectives from the references of the extracted articles. We included only prospective observational studies involving human participants and excluded interventional studies, observational studies that did not report sample sizes, or observational studies that did not research on predictors of CRBD. We narrowed our search to the keyword "prediction" and found five references. We selected five studies that met the objectives of the study as the target literature.

Results: Using the keywords "CRBD" and "catheter-related bladder discomfort", we identified 69 published articles. The results were narrowed down by the keyword "prediction", and five studies that recruited 1,147 patients remained. The predictors of CRBD can be divided into four factors: 1) patient factors; 2) surgical factors; 3) anesthesia factors; and 4) device and insertion technique factors.

Conclusion: Our study suggests that patients with predictors of CRBD should be closely monitored to reduce postoperative patient suffering, and their quality of life should be improved after anesthesia.

Background: There may be an etiological association between obesity and dysmenorrheal traits. This study aimed to observe the relationship between body mass index (BMI) and dysmenorrhea in a general female population.

Methods: Premenopausal adult females (n = 2,805) undergoing health checkups were assessed for data such as the BMI and self-reported severity of dysmenorrhea. The BMI levels were compared according to the severity of dysmenorrhea with adjustment for age, smoking habit, exercise habit, serum lipids, and plasma glucose.

Results: The mean BMI level in females with severe dysmenorrhea (n = 278; 23.3 ± 4.5 (standard deviation) kg/m²) was high relative to those with mild (n = 1,451; 22.3 ± 3.9 kg/m²) and moderate (n = 1,076; 22.6 ± 4.4 kg/m²) dysmenorrhea. Even after adjustment for covariables, the difference in BMI remained significant.

Conclusions: The high-normal BMI level may be seen in severe dysmenorrhea in the general female population. Further research is needed to confirm the findings.

Background: The aim of the study was to identify factors related to the need for hospitalization due to acute alcohol intoxication.

Methods: The data of 42 patients with acute alcohol intoxication who visited our hospital from April 1, 2014 to September 30, 2015 were available for analysis. Factors related to outcome included hospitalization or release to home, Glasgow coma scale (GCS), temperature, pulse rate, blood pressure, oxygen saturation of the peripheral artery (SpO₂), and respiratory rate. A retrospective survey was done that included estimated blood alcohol concentration, osmotic pressure, and serum lactate level. The following formula was used to estimate blood alcohol concentration: (measured osmotic pressure - estimated osmotic pressure × 4.6 mg/dL). Univariate analysis of each variable was done for the two outcome groups, hospital admission or release to home, then statistically significant items were subjected to multivariate analysis.

Results: Of the 42 patients (average age 22.8 ± 8.6 years, 33 men, six women), 29 were admitted and 13 were released to home. There was a weak correlation between estimated blood alcohol concentration and GCS. There was no significant difference in alcohol concentration or GCS between the hospitalized and released to home groups. In multivariate analysis using the outcome as the objective variable, a serum lactate level of 26 mg/dL or higher was associated with the need for hospitalization (odds ratio: 6.7).

Conclusion: A serum lactate level of 26 mg/dL would be useful for deciding if hospitalization is necessary for patients with acute alcohol intoxication.

Background: Atrial fibrillation (AF) is the most common arrhythmia with a growing prevalence worldwide, especially in the elderly population. Patients with AF are at higher risk of serious life-threatening events and complications that may lead to long-term sequelae and reduce quality of life. The aim of our study was to examine the association of additional risk factors and comorbid medical conditions with AF in patients 65 years, or older.

Methods: We performed a retrospective electronic medical record review of patients aged 65 years and older, who visited our internal medicine office between July 1, 2020 and June 30, 2021.

Results: Among 2,433 patients, 418 patients (17.2%) had AF. Our analysis showed that for each unit increased in age, there was a 4.5% increase in the odds of AF (95% confidence interval (CI) 2.2-6.9%; P < 0.001). Compared to patients of Caucasian descent, African-American patients had significantly decreased odds of AF (odds ratio (OR) 0.274, 95% CI 0.141 - 0.531; P < 0.001). Patients with hypertension had 2.241 greater odds of AF (95% CI 1.421 - 3.534; P = 0.001). Additional comorbidities with significantly greater odds of AF included other cardiac arrhythmias (OR 2.523, 95% CI 1.720 - 3.720; P < 0.001), congestive heart failure (OR 3.111, 95% CI 1.674 - 5.784; P < 0.001), osteoarthritis (OR 3.014, 95% CI 2.138 - 4.247; P < 0.001), liver disease (OR 2.129, 95% CI 1.164 - 3.893; P = 0.014), and colorectal disease (OR 1.500 95% CI 1.003 - 2.243; P = 0.048). Comorbidities with significantly decreased odds of AF included other rheumatological disorder (OR 0.144, 95% CI 0.086 - 0.243; P < 0.001), non-steroidal anti-inflammatory drugs (NSAIDs) use (OR 0.206, 95% CI 0.125 - 0.338; P < 0.001), and corticosteroid use (OR 0.553, 95% CI 0.374 - 0.819; P = 0.003).

Conclusions: Increasing age, hypertension, presence of other cardiac arrhythmias, congestive heart failure, osteoarthritis, liver disease, and colorectal disease are associated with increased odds of having AF.

Every-week (ew) adalimumab (ADA) maintenance following induction therapy with a standard induction regimen has recently been approved for use in Japan. The efficacy and safety of combination therapy with ew-ADA maintenance following standard induction regimen plus intensive granulocyte and monocyte adsorptive apheresis (GMA) (two sessions/week) for the treatment of refractory ulcerative colitis (UC) displaying failure of conventional, biologics and Janus kinase inhibitor have not been evaluated previously. The present retrospective study evaluated the 10-week efficacy of this combination therapy among refractory UC patients. Six patients were given initial ADA combination therapy (ADA at 160 mg in week 0, ADA 80 mg in week 2, and 40 mg in week 4, followed by ew-ADA at 40 mg/week) plus intensive GMA. One patient (16.6%) achieved clinical remission and two patients (33.3%) achieved endoscopic improvement by week 10. After excluding two patients who discontinued treatment, mean full Mayo score (P = 0.14), endoscopic subscore (P = 0.18) and C-reactive protein level (P = 0.27) at 10 weeks were numerically decreased compared with baseline in the remaining four cases, although the differences were not significant. Use of ew-ADA maintenance following standard induction regimen plus intensive GMA appears unlikely to achieve satisfactory induction of clinical remission in UC patients for whom conventional agents, biologics and Janus kinase inhibitors have failed.

Background: Diabetes mellitus (DM) and thyroid nodules (TNs) with the risk of malignancy are increasing globally. Hence, we conducted this study to evaluate the prevalence and the associated predictors for DM among adult patients with TNs in Royal Commission Hospital, Kingdom of Saudi Arabia (KSA).

Methods: A retrospective study was conducted between January 1, 2015 and December 31, 2021. Patients with documented TNs based on the American College of Radiology Thyroid Imaging Reporting and Data System (ACR TI-RADS) were recruited. Then the prevalence and associated risk factors for DM were assessed.

Result: Three hundred ninety-one patients who had TNs were recruited. The median (interquartile range (IQR)) age was 46.00 (20.0) years, and 332 (84.9%) of the patients were females. There was a high prevalence of DM (24.0%) among adult patients with TNs. In the univariate analysis, there were significant associations between diagnosed DM among adult patients with TNs and age, gender, 25-hydroxyvitamin D (25(OH)D) level, hypertension, bronchial asthma, free triiodothyronine (FT3), white blood cell count, low-density lipoprotein (LDL), high-density lipoprotein (HDL) and triglycerides. In the multivariate analysis, there were significant associations between diagnosed DM among adult patients with TNs and age (odds ratio (OR) 1.037 (95% confidence interval (CI) 1.012 - 1.062)), hypertension (OR 0.374 (95% CI 0.203 - 0.689)), FT3 level (OR 0.635 (95% CI 0.412 - 0.980)), LDL (OR 0.643 (95% CI 0.456 - 0.907)) and HDL (OR 0.654 (95% CI 0.465 - 0.919)).

Conclusion: There was a high prevalence of DM among patients with TNs. Age, hypertension, FT3, LDL and HDL were significantly associated with DM and TNs.

Background: With this rising popularization of enhanced recovery after surgery (ERAS) protocols, it is important to ask if the current and developing pathways are fully comprehensive for the patient's perioperative experience. Many current pathways discuss aspects of care including fluid management, pain management, and anti-emetic medication regiments, but few delineate recommendations for lung protective strategies. The hypothesis was that intraoperative lung protective strategies would results in improved postoperative lung function.

Methods: One hundred patients at the Medical University of South Carolina undergoing hepatobiliary and colorectal surgeries were randomized to receive intraoperative lung protective techniques or a standard intraoperative ventilation management. Three maximum vital capacity breaths were recorded preoperatively, and postoperatively 30 min, 1 h, and 2 h after anesthesia stop time. Average maximum capacity breaths from all four data collection interactions were analyzed between both study and control cohorts.

Results: There was no significant difference in the preoperative inspiratory capacity between the control and the ERAS group (2,043.3 ± 628.4 mL vs. 2,012.2 ± 895.2 mL; P = 0.84). Additional data analysis showed no statistically significant difference between ERAS and control groups: total average of the inspiratory capacity volumes (1,253.5 ± 593.7 mL vs. 1,390.4 ± 964.9 mL; P = 0.47), preoperative oxygen saturation (97.76±2.3% vs. 98.04±1.7%; P = 0.50), the postoperative oxygen saturation (98.51±1.4% vs. 96.83±14.2%; P = 0.40), and change in inspiratory capacity (95% confidence interval (CI) (-211.2 - 366.6); P = 0.60).

Conclusions: No statistically significant difference in postoperative inspiratory capacities were seen after the implementation of intraoperative lung protective strategies. The addition of other indicators of postoperative lung function like pneumonia incidence or length of inpatient stay while receiving oxygen treatment could provide a fuller picture in future studies, but a higher power will be needed.

Background: Different machine learning (ML) technologies have been applied in healthcare systems with diverse applications. We aimed to determine the model feasibility and accuracy of predicting patient portal use among diabetic patients by using six different ML algorithms. In addition, we also compared model performance accuracy with the use of only essential variables.

Methods: This was a single-center retrospective observational study. From March 1, 2019 to February 28, 2020, we included all diabetic patients from the study emergency department (ED). The primary outcome was the status of patient portal use. A total of 18 variables consisting of patient sociodemographic characteristics, ED and clinic information, and patient medical conditions were included to predict patient portal use. Six ML algorithms (logistic regression, random forest (RF), deep forest, decision tree, multilayer perception, and support vector machine) were used for such predictions. During the initial step, ML predictions were performed with all variables. Then, the essential variables were chosen via feature selection. Patient portal use predictions were repeated with only essential variables. The performance accuracies (overall accuracy, sensitivity, specificity, and area under receiver operating characteristic curve (AUC)) of patient portal predictions were compared.

Results: A total of 77,977 unique patients were placed in our final analysis. Among them, 23.4% (18,223) patients were diabetic mellitus (DM). Patient portal use was found in 26.9% of DM patients. Overall, the accuracy of predicting patient portal use was above 80% among five out of six ML algorithms. The RF outperformed the others when all variables were used for patient portal predictions (accuracy 0.9876, sensitivity 0.9454, specificity 0.9969, and AUC 0.9712). When only eight essential variables were chosen, RF still outperformed the others (accuracy 0.9876, sensitivity 0.9374, specificity 0.9932, and AUC 0.9769).

Conclusion: It is possible to predict patient portal use outcomes when different ML algorithms are used with fair performance accuracy. However, with similar prediction accuracies, the use of feature selection techniques can improve the interpretability of the model by addressing the most relevant features.

Background: The public stigma related to mental illness is the general public's negative misconceptions about people with mental health conditions (PMHCs). The public stigma of mental illness is detrimental to PMHC as it leads to loss of opportunities and unemployment. The aim of the study was to clarify the status of public stigma related to PMHC, focusing on knowledge about mental illness and social distance concerning PMHC.

Methods: A survey was conducted among 970 Japanese office workers aged 20 to 60 years. Accurate knowledge of mental illness was assessed using the Mental Illness and Disorder Understanding Scale (MIDUS). The Attitudinal Social Distance (ASD) was used to determine social distance in relation to PMHC. The demographic characteristics of the participants evaluated were sex, age group measured in years, employment position, employment status, and attendance at mental illness stigma training.

Results: Regular employees (P = 0.03) and those having prior contact experience (P = 0.01) had more accurate knowledge. Participants between 50 to 59 years old (M = 15.87, standard deviation (SD) = 3.35) had greater social distance than those under 30 years old (M = 14.78, SD = 3.97, P < 0.05). The results of multiple linear regression analysis found that employment status (partial r = -0.07, P < 0.05) and prior contact experience (partial r = -0.15, P < 0.01) significantly affected the MIDUS score, whereas no variable had a significant effect on the ASD score.

Conclusions: Accurate knowledge of mental illness was significantly higher among regular employees and those with contact experience. Social distance was significantly lower among those under the age of 30 years.

Remimazolam is a novel benzodiazepine with sedative and amnestic properties similar to midazolam. Ester metabolism results in a half-life of 5 - 10 min and a limited context sensitive half-life. We present preliminary retrospective experience with its use as a primary agent for procedural sedation for brief invasive and noninvasive procedures. The study cohort included seven patients, ranging in age from 14 to 51 years. Remimazolam administration included bolus dosing in two patients and a combination of bolus dosing followed by an infusion in the other five patients. The initial bolus dose of remimazolam ranged from 2.5 to 5 mg. Starting doses for the infusion ranged from 10 to 30 µg/kg/min with titration of the continuous infusion during the procedure, ranging from 10 - 30 µg/kg/min. Median dose infusion requirements were 15 - 20 µg/kg/min. One procedure was completed with remimazolam as the sole anesthetic agent while the other six patients received adjunctive agents. Changes in blood pressure or oxygen saturation were noted which resolved with minimal interventions such as a decrease in remimazolam infusion rate or an increase in supplemental oxygen administration. Our anecdotal experience provides further support for the efficacy of remimazolam as an agent for procedural sedation.
