A stepwise implementation of the Slovenian National Diabetic Retinopathy Screening Program - evaluation of the first 4.5 years.

This retrospective cohort study aimed to assess the characteristics of patients enrolled in the national diabetic retinopathy (DR) screening program and evaluate the selected program's quality elements in the first five years after implementation. Patients who underwent DR screening between February 2018 and June 2022 at the University Medical Centre Ljubljana were included. General patient characteristics (age, sex, type and therapy of diabetes mellitus (DM), duration of DM, blood HbA1c levels), best corrected visual acuity, stage of DR, presence of sight-threatening diabetic retinopathy (STDR), and selected quality indicators (quality of photographs, re-screening interval, time to treatment) were recorded and evaluated. A total of 34 654 screening examinations were performed on 13 513 patients with diabetes. The majority (77.3%) had Type 2 diabetes, with a mean DM duration of 9.74 ± 9.87 years. In 55.9% of patients, DM duration was less than ten years, and the mean HbA1c was 7.33% ± 1.49. DR signs were noted in 29.1% of patients and 0.89% of patients exhibited STDR. After establishing the diagnosis of STDR, treatment was initiated in 3.43 ± 1.98 months. Implementing the DR screening program provides valuable insights into managing diabetic retinopathy nationwide. It allows for the early detection of sight-threatening DR and facilitates timely and effective treatment, which could help prevent severe visual impairment.

Brief Report: Impact of Maintenance Pemetrexed Cessation on Clinical Outcomes of Patients With Metastatic Nonsquamous NSCLC

IntroductionCombination chemoimmunotherapy including pemetrexed and a PD(L)1 inhibitor is a common first-line systemic therapy approach for patients with metastatic nonsquamous NSCLC. Patients often discontinue maintenance pemetrexed due to adverse effects, and little is known about the impact of maintenance pemetrexed cessation on real-world progression-free survival (rwPFS) and overall survival (OS). MethodsA total of 121 patients with stage IV or recurrent, metastatic nonsquamous NSCLC treated at Vanderbilt University Medical Center (VUMC) were included in this retrospective analysis. Patients diagnosed between July 2017 and September 2023 were included if they received maintenance pemetrexed and pembrolizumab. Patients were divided into two groups: those who stopped pemetrexed due to toxicity and those who did not. rwPFS and OS were measured from time of stage IV or metastatic diagnosis to the date of radiographic progression or death, respectively. ResultsAmong patients with stage IV or recurrent, metastatic NSCLC (n = 121), who remained on maintenance pemetrexed and pembrolizumab (n = 68), the median rwPFS was 11.7 months (95% confidence interval [CI]: 7.47–NA) compared with 24.3 months (95% CI, 19.37–NA) among patients who stopped maintenance pemetrexed (n = 53) (p = 0.1). The median OS in the same patient groups was 25.8 months (95% CI: 13.8–NA) compared with 36.4 months (95% CI: 26.9–NA) (p = 0.15), respectively. ConclusionsIn this study of patients with metastatic nonsquamous NSCLC who received maintenance pemetrexed and pembrolizumab, patients who stopped pemetrexed due to toxicity experienced similar outcomes to those who continued with pemetrexed. The optimal duration of maintenance chemotherapy should be further evaluated in the immunotherapy era.

Association of Prostate-Specific Antigen With Age, Digital Rectal Examination, and Lower Urinary Tract Symptoms in the Lebanese Population: A Cross-Sectional Study.

Prostate cancer (PCa) is a leading cause of mortality in men worldwide. Prostate-specific antigen (PSA) testing is a standard method for PCa detection, yet its associationwith age, digital rectal examination (DRE) results, and lower urinary tract symptoms (LUTS) remains understudied, particularly in the Lebanese population. This study aimed to investigate the associationof PSA levels with age, DRE results, and LUTS severity among Lebanese men. A total of 725 men aged 55-70 years were recruited from a men's health campaign at Saint George Hospital University Medical Center in Lebanon. PSA levels, DRE results, andInternational Prostate Symptom Score(IPSS)were assessed. Statistical analysis included Kruskal-Wallis tests and Spearman's rho correlation coefficient. Participants exhibited a significant correlation between age and PSA levels (r = 0.138, p < 0.01). PSA levels varied significantly across age groups (p = 0.029), with higher mean PSA levels observed in older age groups. IPSS status correlated positively with PSA levels (r = 0.23, p < 0.001), indicating higher PSA levels associated with increased LUTS severity. Abnormal DRE findings were significantly associated with elevated PSA levels (p < 0.00), suggesting their potential as an indicator of prostate abnormalities. This study highlights the importance of age-specific reference ranges for PSA levels in the Lebanese population. Elevated PSA levels were associated with older age, increased LUTS severity, and abnormal DRE findings. These findings highlight the significance of integrating PSA testing with clinical assessments for PCa detection and risk stratification in Lebanon.

Effective and safe implementation of robot-assisted donor nephrectomy by experienced laparoscopic surgeons.

In June 2021, the first robot-assisted donor nephrectomy (RADN) was performed at the Leiden University Medical Center (LUMC), the Netherlands. The goal of this study was to investigate whether this procedure has been implemented safely and efficiently. RADN was retrospectively compared to laparoscopic donor nephrectomy (LDN) performed during the same time period (June 2021 until November 2022). Patients were assigned to RADN depending on the availability of the da Vinci robot and surgical team. The studied endpoints were postoperative complications, operative time, estimated blood loss, warm ischemic time (WIT), and postoperative pain experience. For analysis, the Student's t-test and Chi-squared test were used for, respectively, continuous and categorical data. Forty RADN were compared to 63 LDN. Total insufflation time was significantly longer in RADN compared to LDN (188min (169-214) versus 172min (144-194); p=0.02). Additionally, WIT was also found to be significantly higher in the robot-assisted group (04:54min vs. 04:07min; p<0.01). No statistical differences were found in postoperative outcomes (eGFR of the recipient at 3-month follow-up, RADN 54.08mL/min ±18.79 vs. LDN 56.41mL/min ±16.82; p=0.52), pain experience, and complication rate. RADN was safely and efficiently implemented at the LUMC. It's results were not inferior to laparoscopic donor nephrectomy. Operative time and warm ischemic times were longer in RADN. This may relate to a learning curve effect. No clinically relevant effect on postoperative outcomes was observed.

Intraoperative radiotherapy after neurosurgical resection of brain metastases as institutional standard treatment- update of the oncological outcome form a single center cohort after 117 procedures.

Stereotactic radiotherapy (SRT) is the predominant method for the irradiation of resection cavities after resection of brain metastases (BM). Intraoperative radiotherapy (IORT) with 50kV x-rays is an alternative way to irradiate the resection cavity focally. We have already reported the outcome of our first 40 IORT patients treated until 2020. Since then, IORT has become the predominant cavity treatment in our center due to patients´ choice. We retrospectively analyzed the outcomes of all patients who underwent resection of BM and IORT between 2013 and August 2023 at Augsburg University Medical Center (UKA). We identified 105 patients with 117 resected BM treated with 50kV x-ray IORT. Median diameter of the resected metastases was 3.1cm (range 1.3 - 7.0cm). Median applied dose was 20Gy. All patients received standardized follow-up (FU) including three-monthly MRI of the brain. Mean FU was 14months, with a median MRI FU for patients alive of nine months. Median overall survival (OS) of all treated patients was 18.2months (estimated 1-year OS 57.7%). The observed local control (LC) rate of the resection cavity was 90.5% (estimated 1-year LC 84.2%). Distant brain control (DC) was 61.9% (estimated 1-year DC 47.9%). Only 16.2% of all patients needed WBI in the further course of disease. The observed radio necrosis rate was 2.6%. After 117 procedures IORT still appears to be a safe and appealing way to perform cavity RT after neurosurgical resection of BM with low toxicity and excellent LC.

Feasibility and effectiveness of an evidence-based intervention bundle to improve peri-operative care of older adults

BACKGROUND Maintaining functional status is an essential therapeutic goal in peri-operative care of older adults. Although several recommendations concerning peri-operative management are available, pragmatic approaches to their sustainable implementation are lacking. OBJECTIVE Multiple evidence-based recommendations for peri-operative care of older adults were bundled into a multicomponent intervention and assessed for feasibility and effectiveness. DESIGN A quality improvement study with before–after comparison using a hybrid implementation-effectiveness approach. SETTING University Medical Centre. The trial was conducted from 2017 to 2020, follow-up was 1 week, 1 month and 6 months after surgery. PATIENTS Patients at least 65 years old were scheduled for surgery; excluded: intercranial, ophthalmological, and emergency surgery; planned postoperative stay in the intensive care unit. A total of 720 patients were eligible; 278 patients were recruited, 95 (34) of whom were female. INTERVENTIONS The intervention consisted of a set of recommended measures for peri-operative management of older patients, including pre-operative assessment and measures to manage frailty, malnutrition, polypharmacy, cognitive impairment and delirium. Patients were sequentially assigned to three groups: control (no change from usual care), transition (to implementation of the intervention) and intervention (fully implemented). MAIN OUTCOME MEASURES Feasibility was assessed by determining the level of implementation, and barriers were identified by conducting qualitative interviews with the medical staff. Intervention effectiveness was estimated by Instrumental Activities of Daily Living (IADL; Lawton and Brody, primary clinical outcome) 1 and six months postoperatively. The secondary outcomes included postoperative complications, cognitive performance, quality of life and length of hospital stay. RESULTS The implementation rate was 77%. Pre-operative IADL was 9.9/10 (range 8 to 10; SD 0.4) and 9.7/10 (6 to 10, 0.8) for the control and intervention groups, respectively. There was no statistically significant difference between the groups in IADL (0.07, 95% CI −0.23 to 0.36, P = 0.66) and 6 months after surgery (0.01, 95% CI −0.29 to 0.31, P = 0.95). CONCLUSION The implementation of evidence-based interventions to improve peri-operative care of older patients showed good feasibility in clinical routine but did not improve patients’ functional status, which was already at a high level pre-operatively.

Donation After Circulatory Death Cardiac Recovery Technique: Single-Center Observational Outcomes

BackgroundRecovery of hearts from donation after circulatory death donors has been performed either with direct procurement and perfusion (DPP) using the TransMedics Organ Care System or with normothermic regional perfusion (NRP) with subsequent cold storage. It remains unclear which of these 2 strategies yields optimal posttransplant outcomes. MethodsAll heart transplant recipients from donors after circulatory death donors at the Vanderbilt University Medical Center (Nashville, TN) were reviewed (February 2020 to January 2023). Recipients were stratified into an NRP or DPP cohort. All DPP recoveries were performed using the TransMedics Organ Care System. The key outcome was severe primary graft dysfunction at 24 hours, defined by the need for postoperative extracorporeal membrane oxygenation. ResultsA total of 118 hearts were transplanted (NRP, 87; DPP, 31). Donors recovered using NRP were younger (25 years [interquartile range {IQR}, 21-31 years] vs 31 years [IQR, 24-37 years]; P = .008) and had shorter distance traveled (292 miles [158-516 miles] vs 449 miles [IQR, 248-635 miles]; P = .02). Recipient preoperative risk factors were similar between the groups. There was no difference in the incidence of severe primary graft dysfunction at 24 hours (NRP, 5.8%; and DPP, 12.9%; P = .24). However, ejection fraction at 7 days after transplantation was higher in the NRP group (65% [IQR, 60%-65%] vs 60% [IQR, 60%-68%]; P = .005). There was no difference in inotrope scores at 24 hours (P = 1.00) or 72 hours (P = .87) or in 30-day (NRP, 95% vs DPP, 97%; P = .75) and 1-year (NRP, 94% vs DPP, 86%; P = .19) survival. ConclusionsNRP and DPP strategies for recovery of cardiac allografts yield comparable early allograft outcomes. Future studies are needed to confirm these findings in larger prospective cohorts.

Esophageal Atresia with Tracheoesophageal Fistula Is Associated with Consanguinity

Objectives and StudyEsophageal atresia with tracheoesophageal fistula (EA-TEF) is a rare congenital malformation. The incidence of TEF is 1.3-4.6 cases per 10,000 live births. The specific etiology of EA-TEF is unknown. Environmental risk factors, such as maternal medication use and alcohol consumption during pregnancy, are suggested. Genetic factors have also been described, especially among syndromic types, such as Down syndrome, but less among non-syndromic types. The aim of the study is to examine the association between non-syndromic EA-TEF and consanguinity. MethodsA retrospective study comparing the incidence of EA-TEF between low-consanguineous Jewish population and high-consanguineous Bedouin population. All patients were treated at Soroka University Medical Center, the only tertiary medical center in southern Israel. ResultsDuring the years 2000-2022, 579,130 children were born in southern Israel, 386,915 (66.8%) were Jewish, and 192,215 were Bedouin Muslims. A total of 96 patients were diagnosed with EA-TEF, 83 of them were non-syndromic. The incidence of EA-TEF was 1.66 cases per 10,000 live births and was statistically higher among the Bedouin population (3 vs. 0.95 cases per 10,000 live births, P<0.001). The consanguinity rate among the Bedouin group was higher compared with the Jewish (67.8% vs 0% P<0.001). There were no differences in other risk factors. ConclusionThe incidence of EA-TEF is exceptionally higher among the Bedouin population that lives in the same geographic region and has the same medical access as the Jewish population, proposing consanguinity as an important/essential risk factor for EA-TEF.

Management and prognosis of iatrogenic perforations of the cervical oesophagus and hypopharynx.

The study aimed to identify factors affecting the management and prognosis of iatrogenic cervical oesophageal and hypopharyngeal perforations (iCEHPs). We retrospectively analysed 24 patients treated for iCEHP between 2004 and 2021 at a tertiary university medical centre. Data on demographics, clinical features, imaging, management and outcomes were collected. Factors associated with primary management and patient outcome were assessed. The most common management approach was surgical neck exploration (15 patients, 62.5%). Surgical management was used in 93% of uncontained perforations compared to 11% of contained perforations (p < 0.001). Surgically-treated patients had higher levels of C-reactive protein (CRP) than conservatively-treated patients (median, 18.3 vs 4.8 mg/dL; p = 0.001). Delayed diagnosis (≥ 24 hours) was associated with increased mortality (100 vs 5%; p = 0.011). The mortality rate was significantly higher in patients who had a history of neck irradiation than in patients who did not (67 vs 5%; p = 0.032). Early diagnosis of iCEHP improves outcomes. The appropriate management should be carefully selected on the basis of CRP level and imaging findings. Prior neck radiation is a poor prognostic factor.

Outcome after colorectal full-thickness resection and management of recurrence.

Background and study aims Endoscopic full-thickness resection (eFTR) allows treatment of "difficult to resect" lesions not amenable to conventional endoscopic methods. Efficacy and safety of the system have already been proven in numerous studies. Follow-up data on outcome of colorectal eFTR and management of recurrences are still rare. Patients and methods All patients undergoing colorectal eFTR at our institution with at least one endoscopic follow-up examination were retrospectively analyzed. The primary endpoint was the rate of recurrent or residual lesions (RRLs) and the secondary endpoint was the rate of late adverse events (AEs). We further aimed to identify risk factors for RRLs and to describe their management. Results Between November 2014 and 2021, 141 patients underwent eFTR at University Medical Center Freiburg. Ninety-one patients fulfilled the inclusion criteria. Indications for eFTR were non-lifting adenoma (n = 65), subepithelial tumors (n = 18) and early carcinoma (n = 8). The median follow-up period was 17 months (range, 2-86). The overall RRL rate was 9.9% (9/91). A significant proportion of RRLs (6/9, 66%) were detected late. All RRLs occurred in the group of non-lifting adenoma, corresponding to a RRL rate of 13.8% in this subgroup. Thirty-three percent (3/9) were initially treated by hybrid eFTR. Of the RRLs, 66.6% could were successfully treated endoscopically. On χ2 analysis, the hybrid eFTR technique ( P = 0.006) was associated with a higher rate of RRL. No late AEs occurred. Conclusions The rate of RRL after colorectal eFTR is low and the majority could be treated endoscopically. For non-lifting adenomas and early carcinomas, close follow-up is mandatory to detect late recurrence. Long-term outcomes after hybrid eFTR need further investigation.

Body composition of adults with chronic intestinal failure receiving home parenteral nutrition: A descriptive cohort study.

Chronic intestinal failure (CIF) refers to the long-lasting reduction of gut function below the minimum necessary to absorb macronutrients, water, and/or electrolytes. Patients with CIF likely develop various forms of malnutrition and dehydration, yet studies that focus primarily on body composition are lacking. Therefore, this study aimed to evaluate the body composition of adult patients with CIF. This retrospective descriptive cohort study was performed at the Radboud University Medical Center, a tertiary referral center for CIF treatment in the form of home parenteral nutrition. We collected available bioelectrical impedance analysis (BIA) data from routine care between 2019 and 2023. The primary outcome was body composition, which was evaluated by assessing body mass index (BMI), fat-free mass index (FFMI), and fat percentage (fat%). Overall, 147 adult patients with CIF were included with a median (interquartile range) age of 58 (25-68) years; 69% were female. The mean (SD) BMI was 22.1 (4.3) kg/m2, FFMI was 14.2 (1.9) kg/m2 in females and 17.0 (2.0) kg/m2 in males, and fat% was 33.7% (6.8%) in females and 24.6% (6.4%) in males. 63% had an FFMI below references, and 48% had a high fat%. This study found that most adult patients with CIF have an unfavorable body composition characterized by a high fat% and low FFMI despite having a normal mean BMI. These results highlight the necessity for in-depth nutrition assessment, including BIA measurement. Moreover, future studies should focus on exercise interventions to increase FFMI and improve body composition and function.

Testicular sperm extraction for fertility preservation in young patients with cancer.

Cancer survivors in the adolescent and young adult generation often experience marriage, pregnancy, and childbirth after treatment; thus, fertility preservation is very important. In male patients, testicular sperm extraction (TESE) is sometimes performed due to azoospermia. Such a procedure is called oncological TESE (onco-TESE). In the present study, we aimed to define onco-TESE as TESE for fertility preservation in cancer patients, including those receiving gonadotoxic treatment. Seventeen male patients with cancer who had undergone onco-TESE for fertility preservation at Yokohama City University Medical Center between April 2014 and March 2023 were included in the study. Motile testicular sperm were acquired by TESE in 9 out of 17 cases. Among patients who had initiated chemotherapy before surgery, Motile sperm could be acquired by onco-TESE in 3 out of 9 cases. In chemotherapy-naive patients, Motile sperm were acquired by onco-TESE in 6 out of 8 cases. In the end, sperm cryopreservation was performed in 10 patients. Cryopreserved sperm were used in 2 of the 10 cases, and live birth was achieved after intracytoplasmic sperm injection in both cases. Before starting gonadotoxic treatment, it is important to confirm whether the patient desires to bear children. If having a baby is desired, a referral to a reproductive medicine doctor is recommended. Fertility preservation before starting gonadotoxic treatment is preferable, but fertility preservation could be considered even after such a treatment.

Comparison of the Quantra QPlus and ROTEM Goal-Directed Transfusion Protocols in Cardiothoracic Surgery Patients: A Prospective Observational Study

To compare the designed treatment protocols for the Quantra QPlus and rotational thromboelastometry (ROTEM) with regard to transfusion advice. Prospective observational study. Maastricht University Medical Center, The Netherlands. Adults with elective cardiopulmonary bypass surgery with a ROTEM test. ROTEM tests were performed postoperatively for standard monitoring of coagulation status and clinical decision making. Simultaneously, a concurrent sample was analyzed for the Quantra QPlus. A total of 100 samples were analyzed using both the ROTEM and Quantra QPlus. Agreement between the transfusion advice for the ROTEM and Quantra QPlus protocols were compared using Cohen κ values for i.a. fibrinogen, platelet concentrates, and fresh frozen plasma (FFP). The agreement between ROTEM and Quantra QPlus was poor for overall transfusion (0.174) and fibrinogen transfusion (0.300). The agreement of cutoff values for fibrinogen clot stiffness for the Quantra QPlus and EXTEM A10 for the ROTEM was poor (0.160). The fibrinogen clot stiffness and FIBTEM A10 had a moderate agreement (0.731). A Cohen κ could not be calculated for the agreement of protamine, thrombocytes, FFP or cutoff values for these transfusions since frequencies included zero in these cases. The Quantra QPlus transfusion protocol advises transfusion in many non-bleeders, adjustments appear to be necessary. In a small group of cases in which clinically relevant blood loss was observed, the Quantra QPlus advised administration of transfusion products, whereas the ROTEM tests did not. ROTEM-guided and Quantra-guided transfusion did not correspond in this patient group, and agreement was moderate at best. Specificity and sensitivity for transfusion within protocols were heterogeneous between the methods. More clinical research in high-bleeding risk populations is needed to determine the clinical impact of the different protocols.

The Management and Outcomes of Septic Shock Among Surgical Patients at the Jimma University Medical Center, Jimma, Ethiopia: A Prospective Study.

Background and objective Sepsis and septic shock are major healthcare issues in surgical patients admitted to the surgery ward or ICU, affecting millions of people worldwide annually, with a mortality rate between one in three and one in six of those affected.The incidence and mortality of sepsis vary greatly by region, with the highest prevalence in Sub-Saharan Africa, Oceania, South Asia, East Asia, and Southeast Asia. Of all sepsis cases in 2017, 33.1 million people suffered from ill health due to underlying infectious diseases, and 15.8 million suffered from underlying injuries or non-communicable diseases. Methods This prospective observational study was conducted at the Jimma University Medical Centre (JUMC) in Jimma town in southwest Ethiopia, from April 2023 to October 2023. Allsurgical patients aged ≥15 years who presented with or developed septic shock at the Jimma University Medical Centre were included. Results The study involved a total of 61 patients. The median age of the patients was 45 years [interquartile range (IQR): 40-60years], and 77% (n=47) of the patients were male. The most frequent source of infection in this study was community-acquired infection (83.3%, n=49). The most common focus of sepsis was the intra-abdominal infection of the digestive system (82%, n=50). Lactate level testing and blood cultures before administering antibiotics were not done for all septic shock patients. Source control surgery was performed in 52.5% (n=32) of patients after developing septic shock, and 84.4% (n=27) of surgeries were performed within 24 hours. The 30-day mortality rate was 80.3%, with an ICU mortality rate of 78.94%. The median length of stay in the ICU was three days (IQR: 1-5 days), and the median length of hospital stay was six days (IQR: 2-15 days). Conclusions The mortality rate in our cohort washigher compared to that in studies from high-income and low-income countries. There was poor adherence and compliance with the Surviving Sepsis Campaign (SSC) (the one-hour bundle) guidelines. The length of stay in hospitals and ICUs was lower compared to studies from high-income countries due to the high early mortality rates.

Exposure to postoperative hypothermia and its association with complications after major abdominal surgery: a retrospective cohort study.

Many patients who undergo major abdominal surgery experience inadvertent hypothermia during the perioperative period. This study aimed to identify risk factors related to postoperative hypothermia and their association with postoperative complications. This retrospective cohort study used data from Seoul National University Bundang Hospital, a tertiary university medical center in South Korea, between January 1, 2018 and December 31, 2022. We included patients aged ≥18 years who underwent elective major abdominal surgery for more than 2 hours in the operating room. The patients were categorized into the hypothermia (body temperature <36.5℃) and non-hypothermia (body temperature ≥36.5℃) groups. The study sample comprised 30,194 patients, and we classified 21,293 and 8,901 into the hypothermic and non-hypothermic groups, respectively. Some factors associated with the occurrence of postoperative hypothermia included the type of surgery. In the multivariable logistic regression model, the incidence of postoperative complications was 9% higher in the hypothermia group than in the non-hypothermic group (odds ratio [OR], 1.09; 95% confidence interval [CI], 1.01-1.19; P = 0.040). Among postoperative complications, the hypothermic group showed a 14% higher incidence of acute kidney injury (OR, 1.14; 95% CI, 1.04-1.25; P = 0.007) than the non-hypothermic group. The appearance of postoperative hypothermia during the first 30 minutes of the recovery period was significantly associated with the appearance of postoperative complications, especially acute kidney injury. However, further studies are required to validate these findings.

Association between menopause and occupational burnout in healthcare workers: a cross-sectional study

ABSTRACT The increased proportion of women in the workplace and the labor force aging have been demanding investigations of the link between menopause and occupational health issues, especially in healthcare settings. Evidence on the association between menopause and occupational burnout in healthcare settings is still inconclusive. Therefore, we aimed to evaluate the association between menopause and burnout among clinical and non-clinical workers in different occupational health environments. A multi-center, cross-sectional study, applying the Oldenburg Burnout Inventory (OBI) was conducted from September 2021 to March 2023 in University Medical Center (UMC) hospitals in Astana, Kazakhstan. The study involved 125 physicians and nurses and 82 non-clinical administrative and service staff. We found that 63.9% of respondents had disengagement and 61.7% had exhaustion. The affiliated clinical setting was associated with disengagement (p = 0.034), with the highest prevalence among employees in surgical departments (76.9%), while a higher prevalence of exhaustion was found in individuals with different work experience (p = 0.023) and among those who were dissatisfied with their work environment (74.3%). While burnout was identified in almost two-thirds of respondents, the self-reported menopause status of participants was not significantly related to either disengagement (p = 0.34) or exhaustion (p = 0.73), even though a higher prevalence of both was revealed among the postmenopausal group. We propose that healthcare management should understand the importance of burnout among postmenopausal healthcare workers and facilitate open communication and a supportive work environment.

A prediction model based on computed tomography characteristics for identifying malignant from benign sub-centimeter solid pulmonary nodules.

Distinguishing benign from malignant sub-centimeter solid pulmonary nodules (SSPNs) continues to be challenging in clinical practice. Earlier diagnosis is crucial for improving patient survival and prognosis. This study aimed to investigate the risk factors of malignant SSPNs and establish and validate a prediction model based on computed tomography (CT) characteristics to assist in their early diagnosis. A total of 261 consecutive participants with 261 SSPNs were retrospectively recruited between January 2012 and July 2023 from National Cancer Center/National Clinical Research Center for Cancer/Cancer Hospital, Chinese Academy of Medical Sciences and Peking Union Medical College (Center 1), including 161 malignant lesions and 100 benign lesions. Patients were randomly assigned to the training set (n=183) and validation set (n=78) according to a 7:3 ratio. Malignant nodules were confirmed by pathology; and benign nodules were confirmed by follow-up or pathology. Clinical data and CT features were collected to estimate the independent predictors of malignancy of SSPN with multivariate logistic analysis. A clinical prediction model was subsequently established by logistic regression. Furthermore, an additional 69 consecutive patients with 69 SSPNs from The Fourth Hospital of Hebei Medical University (Center 2) between January 2022 and December 2022 were retrospectively included as an external cohort to validate the predictive efficacy of the model. The performance of the prediction model was assessed by sensitivity, specificity, and the area under the receiver operating characteristic curve. There were 113 (61.7%), 48 (61.5%) and 28 (40.6%) malignant SSPNs in the training, internal and external validation sets, respectively. Multivariate logistic analysis revealed four independent predictors of malignant SSPNs: tumor-lung interface (P=0.002), spiculation (P=0.04), air bronchogram (P=0.047), and invisible at the mediastinal window (P=0.003). The area under the curve (AUC) for the prediction model in the training set was 0.875 [95% confidence interval (CI): 0.818, 0.933]; and the sensitivity and specificity were 94.7% and 68.6%, respectively. The AUCs in the internal and external validation set were (0.781; 95% CI: 0.664, 0.897) and (0.873; 95% CI: 0.791, 0.955), respectively; the sensitivity and specificity were 66.7% and 83.3% for the internal validation data, and 100.0% and 61.0% for the external validation data, respectively. The prediction model based on CT characteristics could be helpful for distinguishing malignant SSPNs from benign ones.

Investigation of outcomes following transcatheter edge to edge repair of the mitral valve versus medical management alone in patients with cardiogenic shock and mitral regurgitation

Study objectiveAssessing if Transcatheter Edge to Edge Repair (TEER) with Mitraclip™ in patients with moderate to severe mitral regurgitation (MR) and cardiogenic shock (CS) improves outcomes compared to medical management alone. DesignA single-center, retrospective study was performed in an urban tertiary referral center. SettingRush University Medical Center, United States. ParticipantsAdult patients presenting with CS and moderate to severe MR between 2012 and 2021 were included. InterventionsUndergoing Mitral TEER with Mitraclip versus medical management alone. Main outcome measuresMajor adverse cardiovascular events (MACE) defined as cardiovascular death, heart failure admission, stroke, and myocardial infarction assessed at 30 days, 6 months, and 1 year. The secondary outcome was a change in New York Heart Association (NYHA) classification at 30 days and 6 months. ResultsThere were 28 patients included in the medical management and 33 in the mitral valve TEER groups. There was a decreased MACE in the intervention group at 30 days (24.2 % vs. 46.4 %, p ≤0.001) and 6 months (27 % vs. 75 %, p = 0.002), though not at 1 year (29.4 % vs. 41.7 %, p = 0.42). At 30 days, more patients in the mitral valve TEER group improved to NYHA classes I/II compared to medical management alone (10 [35.7 %] vs. 16 [50 %], p = 0.043). There were no differences in NYHA classes I/II at 6 months (7 [43.7 %] vs. 13 [54.2 %], p = 0.63). ConclusionMitral valve TEER using the Mitraclip™ system improves mid-term cardiovascular compared to medical management alone in patients with CS but does not improve mortality.

Analysis of the Justice Component of a JEDI (Justice, Equity, Diversity, and Inclusion) Inventory in a College of Pharmacy.

At the University of Nebraska Medical Center College of Pharmacy, a longitudinal project is underway to assess how the college is functioning in terms of keeping Justice, Equity, Diversity, and Inclusion (JEDI) at the forefront of the institution. This study is intended to showcase areas of excellence within the college and as a quality improvement exercise to show the institution potential areas in need of improvement. This process was also initiated because such assessments may soon become a requirement for colleges of pharmacy to earn full accreditation. Upon analyzing the Justice component of JEDI and the 32 justice-related ideas that were recommended for exploration and discussion, and further sub-categorized under the terms representation, curriculum and education, policies and procedures, support and resources, and college climate, useful data were discovered. Overall, the information found on representation, policy and procedure, and college climate was difficult to quantify as much of the information was subjective; however, this does not automatically discount this information from being useful. Information relating to curriculum and education was more quantifiable but may be underrepresented. Analyzing information found relating to resources was made possible by identifying readily available support offered at the college for faculty, staff, and students. In identifying these resources, the college was able to take note of any missing support that needed to be implemented to ensure justice was being maintained. This longitudinal process not only allows the college to see areas where they thrive, but it also highlights any shortcomings of the college while providing the institution with information to spark innovative ideas to strengthen and further promote justice.

Positive health: An integrated quantitative approach in patients with chronic gastrointestinal and hepato-pancreatico-biliary disorders.

The concept of positive health (PH) supports an integrated approach for patients by taking into account six dimensions of health. This approach is especially relevant for patients with chronic disorders. Chronic gastrointestinal and hepato-pancreatico-biliary (GI-HPB) disorders are among the top-6 of the most prevalent chronically affected organ systems. The impact of chronic GI-HPB disorders on individuals may be disproportionally high because: (1) The affected organ system frequently contributes to a malnourished state; and (2) persons with chronic GI-HPB disorders are often younger than persons with chronic diseases in other organ systems. To describe and quantify the dimensions of PH in patients with chronic GI-HPB disorders. Prospective, observational questionnaire study performed between 2019 and 2021 in 235 patients with a chronic GI-HPB disorder attending the Outpatient Department of the Maastricht University Medical Center. Validated questionnaires and data from patient files were used to quantify the six dimensions of PH. Internal consistency was tested with McDonald's Omega. Zero-order Pearson correlations and t-tests were used to assess associations and differences. A P value < 0.05 was considered significant. The GI-HPB patients scored significantly worse in all dimensions of PH compared to control data or norm scores from the general population. Regarding quality of life, participation and daily functioning, GI-HPB patients scored in the same range as patients with chronic disorders in other organ systems, but depressive symptoms (in 35%) and malnutrition (in 45%) were more frequent in patients with chronic GI-HPB disorders. Intercorrelation scores between the six dimensions were only very weak to weak, forcing us to quantify each domain separately. All six dimensions of PH are impaired in the GI-HPB patients. Malnutrition and depressive symptoms are more prevalent compared to patients with chronic disorders in other organ systems.
