Psychological well-being of healthcare workers during COVID-19 in a mental health institution.

INTRODUCTION: This study examined the psychological wellbeing of Healthcare Workers (HCWs) during COVID-19 in a mental health setting, associations of psychosocial wellbeing with coping style, and ways that organisations can mitigate the psychosocial burden on HCWs. METHODS: Thirty-seven Mental HCWs (MHCWs) from infected and non-infected wards (control group), were recruited and assessed at three timepoints. Psychological wellbeing, perceived cohesion, and coping style (Brief-COPE) were assessed. Reports on individual coping and feedback on the organisation were collected through in-depth interview. Comparison between infected and non-infected wards, as well as comparison of psychosocial measures and perceived cohesion, across the three timepoints were made. As there were no significant changes in coping styles across the timepoints, Timepoint 1 (T1) coping style was used to correlate with the psychosocial measures across all timepoints. Thematic analysis was used for qualitative data. RESULTS: MHCWs from infected wards reported significantly higher levels of stress, χ2(1) = 6.74, p = 0.009, effect size: medium (ε2 = 0.198), and more severe sleep disturbance (PSQI), χ2(1) = 6.20, p = 0.013, effect size: medium (ε2 = 0.182), as compared to the control group at T2. They also engaged in more problem-focused coping (T2 and T3) and emotion-focused coping (T2). As expected, negative coping style was correlated with negative outcomes except problem-focused coping that was correlated with both negative (sleep disturbance and anxiety symptoms) and positive outcomes (wellbeing). Emotion-focused coping was moderately correlated (Tb = 0.348, p<0.017) with higher levels of wellbeing at T2. Thematic analyses revealed MHCWs felt supported by the responsiveness of the institution, emotional and informational support, and the availability from direct leaders, presence of team and hospital leaders on the ground, helped build trust and confidence in the leadership. CONCLUSIONS: MHCWs experienced significantly higher levels of stress and sleep disturbance during COVID-19. The ways that organizations can offset the psychological burden of pandemics on MHCWs are discussed.

Trends and projection in the proportion of (heavy) cannabis use in Germany from 1995 to 2021.

AIMS: To measure the current trends of cannabis use in Germany, measure trends in the proportion of heavy cannabis users and estimate future cannabis use rates. DESIGN: Repeated waves of the Epidemiological Survey on Substance Abuse, a cross-sectional survey conducted between 1995 and 2021 with a two-stage participant selection strategy where respondents completed a survey on substance use delivered through the post, over the telephone or on-line. SETTING: Germany. PARTICIPANTS/CASES: German-speaking participants aged between 18 and 59 years living in Germany who self-reported on their cannabis use in the past 12 months (n = 78 678). With the application of a weighting scheme, the data are nationally representative. MEASUREMENTS: Questions on the frequency of cannabis use in the past 12 months and self-reported changes in frequency of use due to the COVID-19 pandemic. FINDINGS: The prevalence of past 12-month cannabis users increased from 4.4% [95% confidence interval (CI) = 3.7, 5.1] in 1995 to 10.0% (95% CI = 8.9, 11.3) in 2021. Modeling these trends revealed a significant increase that accelerated over the past decade. The proportion of heavy cannabis users [cannabis use (almost) daily or at least 200 times per year] among past-year users has remained steady from 1995 (11.4%, 95% CI = 7.7, 16.5) to 2018 (9.5%, 95% CI = 7.6, 11.9), but significantly increased to 15.7% (95% CI = 13.1, 18.8) in 2021 during the COVID-19 pandemic. Extrapolating from these models, the prevalence of 12-month cannabis users in 2024 is expected to range between 10.4 and 15.0%, while the proportion of heavy cannabis users is unclear. CONCLUSIONS: Trends from 1995 to 2021 suggest that the prevalence of past 12-month cannabis users in Germany will continue to increase, with expected rates between 10.4 and 15.0% for the German-speaking adult population, and that at least one in 10 cannabis users will continue to use cannabis heavily (almost daily or 200 + times in the past year).

Pancreatic Neuroendocrine Tumors: The Effect of Facility Type on Patient Survival.

OBJECTIVES: During the last decades, significant progress has been made in the management of patients with pancreatic neuroendocrine tumors (pNETs). It is unclear how the type of the treating health care facility alters patient outcomes. METHODS: Data from pNETs reported to the National Cancer Database between 2004 and 2016 were examined. Types of institutions were as follows: academic/research cancer program (ARP), comprehensive community cancer program (CCCP), integrated network cancer program (INCP), and community cancer program (CCP). RESULTS: A total of 17,887 patients with pNETs were analyzed. Treatment at ARPs was significantly associated with receipt of surgery (ARP, 61.9%; CCCP, 45.6%; CCP, 29.9%; INCP, 55.5%; P < 0.001), both for patients with very early tumors ≤2 cm (ARP, 74.7%; CCCP, 66.5%; CCP, 52.4%; INCP, 71.6%; P < 0.001) and for patients with liver metastases (ARP, 21.3%; CCCP, 10.6%; CCP, 5%; INCP, 16.8%; P < 0.001). Treatment at ARPs was associated with improved survival (median overall survival: ARP, 91 mo; CCCP, 47 mo; CCP, 24.5 mo; INCP, 72 mo; P < 0.001). CONCLUSIONS: Treatment of pNETs at academic/research programs is associated with more frequent resections and best survival outcomes. This survival benefit exists for early and late stages and after adjusting for known cofactors.

Outcomes of the Macroscopically Normal Appendix Left in Situ in Patients with Suspected Appendicitis.

BACKGROUND: Right iliac fossa (RIF) pain is a common indication for laparoscopy to diagnose and treat appendicitis. When a macroscopically normal appendix is found, there is no standard consensus regarding excision. Some surgeons remove the appendix due to the risk of microscopic inflammation and to avoid a future, repeat laparoscopy for possible appendicitis. Alternatively, others leave the appendix in situ to avoid morbidity from a potentially unnecessary procedure. We aimed to evaluate the outcomes of patients with macroscopically normal appendices left in situ. METHODS: All emergency laparoscopies without appendicectomy between January 1st 2010- December 31st 2020 were identified from theatre records. All operative notes were individually evaluated and comments on the macroscopic appearance of the appendix and any intra-operative pathology were recorded. Only patients undergoing laparoscopy for suspected appendicitis with macroscopically normal appendices were included. RESULTS: A total of 120 patients [median age 21.68 (range 9-90.8) years] were included. The cohort was predominantly female (n=105, 87.5%). Forty-eight patients (40.0%) had a positive finding during index laparoscopy. During a median duration of 94.5 (range 8-131) months' follow-up, 16 patients (13.33%) underwent a repeat laparoscopy for recurrent RIF pain. Thirteen (10.8% of total cohort) subsequently underwent an appendicectomy. Histology confirmed acute appendicitis in six cases (4.17% of entire cohort). On subanalysis of smaller cohort, index laparoscopies with no positive findings (n=72), nine patients (12.5%) underwent appendicectomy with two (2.7%) appendices demonstrating appendicitis on histological examination. CONCLUSION: 87% of the total cohort with a normal appendix at laparoscopy for RIF pain did not undergo further laparoscopy. Less than 5% of the total cohort and 2.7% of subanalysis cohort had an appendicectomy for histologically-proven appendicitis within the follow-up period. From the evidence in this study, we conclude that leaving the appendix in situ unless macroscopically inflamed is a viable alternative to excision.

A New Angle Measurement in Translabial Ultrasound as an Adjunct for the Diagnosis of Pelvic Organ Prolapse.

The aim of this study was to compare the data obtained by a pelvic organ prolapse quantification (POP-Q) examination with the translabial ultrasound (TLUS) quantification of prolapse, using a new method of angle measurement. We analyzed the TLUS and POP-Q exam findings of 452 patients with symptoms of POP. The POP-Q system was used for clinical staging. TLUS was performed both at rest, and during the Valsalva maneuver after proper preparation. A horizontal reference line was drawn through the inferior margin of the symphysis pubis and the levator plate connected to the rectal ampulla, and the difference was calculated between the rest and the Valsalva maneuver. The Spearman's correlation coefficient of agreement between the TLUS and the clinical POP-Q staging was used for statistical analysis. There was a weak degree of correlation between the POP-Q findings for the Ap parameter and our new angle measurement (rho = 0.17, p < 0.001). Thus, POP staging in conjunction with TLUS with this new angle measurement shows better agreement for the diagnosis of POP than POP-Q staging alone.

A One-Session Treatment of PTSD After Single Sexual Assault Trauma. A Pilot Study of the WONSA MLI Project: A Randomized Controlled Trial.

Sexual abuse is a crime with devastating health consequences. Accessible, acceptable and affordable treatment of PTSD after sexual abuse is important. In this pilot study, a one-session PTSD treatment and a modified perspective to PTSD treatment is introduced. The aim of the study was to test the efficacy of one session of Modified Lifespan Integration (MLI) on reduction of symptoms of PTSD in individuals with PTSD after one sexual assault. This was a single-center, individually randomized waitlist-controlled treatment study with 1:1 allocation, with the intervention of one 90 - 140 minutes session of MLI and with post-treatment follow-up at 3 weeks (time point two). All participants were females, mean age 24, with PTSD symptoms after one sexual assault during the past 5 years. Exclusion criteria were poor understanding of Swedish, multiple traumas, active substance abuse, active psychosis, ADHD, or autism spectrum disorder. Of 135 interested participants, 38 were finally included, 36 completed baseline measures and were included in the intent to treat analyses and 33 were analyzed per protocol. The primary outcome was the difference between the two trial arms in mean PTSD symptoms as measured by the Impact of Event Scale Revised (IES-R) at time point two. In the intervention arm, 72% no longer scored PTSD in per-protocol analysis, compared to 6% in the waiting list arm. IES-R scores were on average halved in the intervention arm (F=21.37, P<0.001), but were essentially unchanged in the waiting list arm. No adverse effects or drop-outs were seen. One session of Modified Lifespan Integration was an effective treatment with a low drop-out rate for females aged 15-65 with PTSD after one sexual assault. Provided that this result can be replicated, MLI should be offered to these patients in clinical settings. Registration number NCT03141047 was given 03/25/2016 at ClinicalTrials.gov (https://register.clinicaltrials.gov/).

Comparing weight-based dosing of tacrolimus XR in obese and non-obese renal transplant recipients.

The recommended initial weight-based dose of extended-release (XR) tacrolimus (Envarsus XR) in kidney transplant recipients (KTR) is 0.14 mg/kg/day. However, no data exist regarding dosing recommendations for obese patients specifically. The aim of this study was to evaluate weight-based dosing requirements in a cohort of obese KTR who were initiated on de novo tacrolimus XR post-transplantation. The primary outcome was weight-based dosing requirements (mg/kg/day) on post-operative day (POD) 7 and 14. Of the 254 KTR, 81 (31%) were obese. The median therapeutic dose on POD7 was 0.1 versus 0.12 vs. 0.14 mg/kg/day in the BMI > 30 kg/m2 , BMI 25-30 kg/m2 , and BMI < 25 kg/m2 , respectively, (p = .0001). This result was similar on POD14; median therapeutic dose was 0.09 versus 0.11 versus 0.15 mg/kg/day in the BMI > 30 kg/m2 , BMI 25-30 kg/m2 , and BMI < 25 kg/m2 , respectively, (p < .001). Therapeutic dose on POD7 and POD14 based on ideal body was similar in all cohorts (p = .238, p = .923, respectively). This finding was supported by a strong linear relationship between ideal body weight (IBW) and therapeutic dose (r = .929). In both obese and non-obese KTR, IBW had a stronger correlation with the therapeutic dose for tacrolimus XR.

Colovesical Fistulae: The Varying Aetiologies.

The most common presenting symptoms of colovesical fistulae (CVF) are pneumaturia and fecaluria. The most important aspect remains not only to investigate the aetiology, and the degree of both severity and complexity, but also the subsequent influence of this on overall management. In a younger population, management usually consists of curative surgery. However, this may not be possible in older patients where surgical candidacy is a genuine concern and a clinical challenge arises relating to pursuing a conservative strategy. We attempted to briefly outline how two patients were managed with a similar non-surgical approach due to frailty. These cases attempt to highlight the importance of multi-disciplinary specialty input, with a view to optimising patient care.

Cholecystitis, Concealment of Hepatobiliary-Pancreatic Pathology: The Role of Endoscopic Retrograde Cholangiopancreatography and Endoscopic Ultrasound.

Cholecystitis is an inflammation of the gallbladder with classic symptoms of right upper quadrant abdominal pain and fever. The most common precipitating factor is cholelithiasis; however, it sometimes appears in conjunction with other hepatobiliary-pancreatic pathology. Management is generally done with antibiotics and supportive care with or without cholecystectomy. The surgical management in practice is often limited by surgery time and patient suitability considering their likely overall outcome. We have outlined two cases with different etiologies presenting as cholecystitis. The aim was to further understand the benefits of multidisciplinary team meetings to optimize patient care and emphasize the roles of endoscopic ultrasonography and endoscopic retrograde cholangiopancreatography in hepatobiliary pathology.

Single-Incision vs. Multiport Robotic Sacrocolpopexy: 126 Consecutive Cases at a Single Institution.

Robot-assisted laparoscopic sacrocolpopexy (RSC) has gained popularity as a method for easier intracorporeal suturing than conventional laparoscopic sacrocolpopexy. However, few studies have compared multiport RSC (MP-RSC) and single-incision RSC (SI-RSC). We aimed to compare perioperative outcomes between these techniques for advanced pelvic organ prolapse (POP). We analyzed 126 patients who underwent RSC for POP quantification (all stage III to IV) between March 2019 and May 2021 at Seoul Asan Medical Center. We prospectively collected operation-related data, including total operation time (OT; from skin incision to closure) and perioperative outcomes. A total of 106 and 20 patients underwent MP-RSC and SI-RSC, respectively. The mean ages were 57.49 ± 10.89 and 56.20 ± 10.30 years in the MP-RSC and SI-RSC groups, respectively. The mean total OT was significantly shorter for MP-RSC than for SI-RSC (105.43 ± 24.03 vs. 121.10 ± 26.28 min). The OT difference was 15.67 min (95% confidence interval, 3.90-25.85, p = 0.009). No statistically significant differences were observed in terms of perioperative variables (estimated blood loss, hospital stay) and postoperative adverse events (POP recurrence, mesh erosion). SI-RSC had comparable intraoperative and postoperative outcomes to MP-RSC, with additional cosmetic benefits. MP-RSC had significantly shorter OT than SI-RSC.

Importance of Translabial Ultrasound for the Diagnosis of Pelvic Organ Prolapse and Its Correlation with the POP-Q Examination: Analysis of 363 Cases.

The incidence of pelvic organ prolapse (POP) is increasing in our aging society. We aimed to evaluate the clinical usefulness of translabial ultrasound (TLUS) by comparing the findings of POP-Q examination and TLUS in advanced POP patients and we also aimed to evaluate the prevalence of rectocele and enterocele on the TLUS. We analyzed the TLUS and POP-Q exam findings of 363 symptomatic POP patients who visited our clinic from March 2019 to April 2021. We excluded three patients who had conditions mimicking POP, as revealed by the TLUS. The most common POP type was anterior compartment POP (68.61%), followed by apical compartment (38.61%) and posterior compartment (16.11%) POP. Agreement between the POP-Q exam and TLUS was tested using Cohen's kappa (κ). p values < 0.05 were considered statistically significant. The incidence of rectocele or enterocele was only 1.67% (6/360) and there was no rectocele or enterocele in most patients (246/252, 96.63%) when the POP-Q exam revealed posterior compartment POP, suggesting that they only had posterior vaginal wall relaxation. The positive predictive value of the POP-Q exam for detecting rectocele or enterocele (as revealed by TLUS) was only 2.38%, whereas the negative predictive value was 100%. In conclusion, the application of TLUS is useful in the diagnosis of POP, especially for differentiation of true POP from conditions mimicking POP. The correlation between the POP-Q exam and TLUS is low, especially in posterior compartment POP, and therefore, patients with POP-Q exam findings suggesting posterior compartment POP should undergo TLUS to check for rectocele or enterocele. The use of TLUS in the diagnosis of POP patients can improve the accuracy of the diagnosis of POP patients in conjunction with a POP-Q exam.

Single-Incision versus Multiport Robotic Myomectomy: A Propensity Score Matched Analysis of Surgical Outcomes and Surgical Tips.

We aimed to compare the perioperative outcomes of single-incision robotic myomectomy (SIRM) and multiport robotic myomectomy (MPRM) and provide surgical tips. We retrospectively analyzed the medical records of 462 patients with symptomatic leiomyoma who underwent MPRM or SIRM between March 2019 and April 2021. Demographic characteristics and surgical outcomes, including the total operative time (OT), estimated blood loss (EBL), and surgical complication rate, were compared between the two groups. Patients in the SIRM group had lower a body mass index and rate of previous pelvic surgery and were younger than those in the MPRM group. The myoma type was not different between groups; however, the MPRM group had larger, and more myomas than the SIRM group. After propensity score matching, these variables were not significantly different between the groups. The total OT, EBL, difference in hemoglobin levels, transfusion rate, and postoperative fever were not different between the groups. No postoperative complications occurred in the SIRM group. In the MPRM group, one patient needed conversion to laparotomy, and two patients had postoperative complications (umbilical incisional hernia and acute kidney injury). In conclusion, both MPRM and SIRM are feasible and effective surgical options for symptomatic myomas with cosmetic benefits and minimal risk of laparotomy conversion.

Barriers to the access and utilization of healthcare for trafficked youth in the United States.

BACKGROUND: Child trafficking is a pervasive public health problem in the United States, with significant health consequences for survivors. Previous studies demonstrated that survivors face barriers to healthcare, though much of the literature has not solely focused on domestic child trafficking. OBJECTIVE: To identify barriers to healthcare faced by survivors of child trafficking in the United States, and to characterize the landscape of available trauma-informed medical services. PARTICIPANTS: 62 adult survivors of child trafficking (83% female, 10% male, 7% transgender; 90% sex trafficking, 25% labor trafficking; median age of entry 16) and 37 community agency professionals who work with trafficked children. SETTING: The United States of America. METHODS: The Barriers to Care Questionnaire (BCQ) was adapted, piloted with a focus group, and disseminated to participants. RESULTS: A statistically significant increase in survivors seeking healthcare after compared to before trafficking was demonstrated (p < 0.05). Eighteen consequential barriers to healthcare were identified. The marginalization domain, representing the individual's perception of negative experiences with the healthcare system, had the highest number of consequential barriers. The majority of survivor and agency participants felt the physical and mental health needs of survivors are not being met, but would seek out trauma-informed healthcare if it were available in their community. CONCLUSIONS: Survivors of child trafficking in the U.S. experience a wide range of barriers to healthcare, and a lack of available trauma-informed healthcare. This study identified barriers to healthcare that can be considered by providers hoping to provide accessible and truama-informed services to trafficked children.

Pelvic Organ Prolapse Is Associated with Osteoporosis in Korean Women: Analysis of the Health Insurance Review and Assessment Service National Patient Sample.

BACKGROUND AND OBJECTIVES: Pelvic organ prolapse (POP) and osteoporosis are major disease entities in older women that have the same epidemiology and might also have the same molecular physiology. However, few data have been reported on the relationship between POP and osteoporosis. We designed this study to examine the association between POP and osteoporosis in Korean women. MATERIALS AND METHODS: We used the Health Insurance Review and Assessment Service 2015 to 2017 National Patient Sample (HIRA-NPS). A total of 4,368,141 individuals were included in this study, and a total of 842,228 individuals aged 50 years and above were included in the final analysis. POP patients were defined by the Korean Informative Classification of Diseases (KOICD) codes (KCD-7, N81, or N99.3) and patients who underwent a pelvic reconstructive procedure. The osteoporosis patients were defined by KOICD (KCD-7, R4113, R3620, R0402,) who were prescribed osteoporosis medication. A 1:10 age-stratified matching and chi-squared test were used for statistical analysis, and p < 0.05 was considered as significant. RESULTS: A total of 7359 women were included in this analysis. Advanced POP was correlated with osteoporosis in Korean women aged 50 years and above in 2015-2017 (p < 0.0001). After adjusting for age, advanced POP was correlated with osteoporosis in the 2015, 2016, and 2017 dataset (p = 0.013, 0.0009, 0.0119, respectively). CONCLUSIONS: Advanced POP is correlated with osteoporosis in Korean women aged 50 years and above. Evaluation for osteoporosis and education about bone health can be especially important, even in relatively young women, aged 50-59 years, and POP patients.

Large-scale evaluation of the Positive and Negative Syndrome Scale (PANSS) symptom architecture in schizophrenia.

Although the Positive and Negative Syndrome Scale (PANSS) is widely utilized in schizophrenia research, variability in specific item loading exist, hindering reproducibility and generalizability of findings across schizophrenia samples. We aim to establish a common PANSS factor structure from a large multi-ethnic sample and validate it against a meta-analysis of existing PANSS models. Schizophrenia participants (N = 3511) included in the current study were part of the Singapore Translational and Clinical Research Program (STCRP) and the Clinical Antipsychotic Trials for Intervention Effectiveness (CATIE). Exploratory Factor Analysis (EFA) was conducted to identify the factor structure of PANSS and validated with a meta-analysis (N = 16,171) of existing PANSS models. Temporal stability of the PANSS model and generalizability to individuals at ultra-high risk (UHR) of psychosis were evaluated. A five-factor solution best fit the PANSS data. These were the i) Positive, ii) Negative, iii) Cognitive/disorganization, iv) Depression/anxiety and v) Hostility factors. Convergence of PANSS symptom architecture between EFA model and meta-analysis was observed. Modest longitudinal reliability was observed. The schizophrenia derived PANSS factor model fit the UHR population, but not vice versa. We found that two other domains, Social Amotivation (SA) and Diminished Expression (DE), were nested within the negative symptoms factor. Here, we report one of the largest transethnic factorial structures of PANSS symptom domains (N = 19,682). Evidence reported here serves as crucial consolidation of a common PANSS structure that could aid in furthering our understanding of schizophrenia.

Altered Composition of Microbiota in Women with Ovarian Endometrioma: Microbiome Analyses of Extracellular Vesicles in the Peritoneal Fluid.

Human microbiota refers to living microorganisms which colonize our body and crucially contribute to the metabolism of nutrients and various physiologic functions. According to recently accumulated evidence, human microbiota dysbiosis in the genital tract or pelvic cavity could be involved in the pathogenesis and/or pathophysiology of endometriosis. We aimed to investigate whether the composition of microbiome is altered in the peritoneal fluid in women with endometriosis. We recruited 45 women with histological evidence of ovarian endometrioma and 45 surgical controls without endometriosis. Following the isolation of extracellular vesicles from peritoneal fluid samples from women with and without endometriosis, bacterial genomic DNA was sequenced using next-generation sequencing of the 16S rDNA V3-V4 regions. Diversity analysis showed significant differences in the microbial community at phylum, class, order, family, and genus levels between the two groups. The abundance of Acinetobacter, Pseudomonas, Streptococcus, and Enhydrobacter significantly increased while the abundance of Propionibacterium, Actinomyces, and Rothia significantly decreased in the endometriosis group compared with those in the control group (p < 0.05). These findings strongly suggest that microbiome composition is altered in the peritoneal environment in women with endometriosis. Further studies are necessary to verify whether dysbiosis itself can cause establishment and/or progression of endometriosis.

A New Case of Herlyn-Werner-Wunderlich Syndrome: Uterine Didelphys with Unilateral Cervical Dysgenesis, Vaginal Agenesis, Cervical Distal Ureteral Remnant Fistula, Ureterocele, and Renal Agenesis in a Patient with Contralateral Multicystic Dysplastic Kidney.

The aim of this study was to present a new case of congenital Herlyn-Werner-Wunderlich syndrome, a rare anomaly of the female reproductive tract, and review the related literature. A 12-year-old girl presented with severe dysmenorrhea since menarche and magnetic resonance imaging showing a bicornuate uterus, double cervix, right hematometra, and hematosalpinx with ipsilateral renal agenesis, accompanied by a remnant distal ureter with hydroureter. A diagnostic cystoscopy and a reduced-port robot-assisted laparoscopy with chromopertubation were performed in order to identify the anomaly. Uterine didelphys and right cervical dysgenesis with ipsilateral vaginal agenesis, cervical distal ureteral remnant fistula, ureterocele, and renal agenesis were diagnosed on the basis of histopathologic findings, and she subsequently underwent a robotic unilateral right total hysterectomy with salpingectomy. This case report reinforces the importance of the intraoperative biopsy for an accurate diagnosis, despite magnetic resonance imaging being considered the gold-standard diagnostic tool.

The Role of Reproductive Autonomy in Adolescent Contraceptive Choice and Acceptance of Long-acting Reversible Contraception.

STUDY OBJECTIVE: To examine the association between reproductive autonomy and adolescent receptivity toward long-acting reversible contraceptive (LARC) methods. DESIGN: A survey to assess sexual history and contraceptive practices/knowledge/attitudes was administered. Reproductive autonomy was measured with an adapted validated scale. SETTING: Adolescent medicine clinic in an urban academic medical center in the Midwestern United States. PARTICIPANTS: Girls ages 14-21 years who presented for well or contraceptive visits. INTERVENTIONS AND MAIN OUTCOME MEASURES: Primary outcome was a favorable rating toward the question "How much do you like the idea of LARC for yourself?" The primary independent variable was the reproductive autonomy decision-making subscale score (higher score indicating increased autonomy). RESULTS: Eighty-nine participants with a mean age of 16 years completed surveys. Almost all (92%) identified as African American. At study enrollment 56.2% were using Depo-Provera (Pfizer), 15.7% oral contraceptives, 3.4% implants, and 24.7% no method. Only 13.5% of participants liked the idea of LARC for themselves. The mean score on the decision-making subscale was 9 (range, 4-12). In bivariable analysis, age was associated with decision-making subscale score, but was not retained as a confounder in multivariable analysis. The odds of liking LARC decreased by 30% with each unit increase in the autonomy decision-making subscale score (odds ratio, 0.70; 95% confidence interval, 0.52-0.94; P = .02). CONCLUSION: Our findings suggest that adolescents with higher reproductive autonomy, measured according to their score on the decision-making subscale, were less likely to favor LARC. Further research should explore participants' perceptions of autonomy and the relational dynamics between adolescents and their parents/partners in contraceptive choice.

pH-Sensitive Folic Acid Conjugated Alginate Nanoparticle for Induction of Cancer-Specific Fluorescence Imaging.

In cancer nanomedicine, numerous studies have been conducted on the surface modification and transport capacity of nanoparticles (NPs); however, biological barriers, such as enzymatic degradation or non-specific delivery during circulation, remain to be cleared. Herein, we developed pH-sensitive NPs that degrade in an acidic environment and release 5-aminolevulinic acid (5ALA) to the target site. NPs were prepared by conjugating alginate with folic acid, followed by encapsulation of 5ALA through a water-in-oil (W/O) emulsion method. The alginate-conjugated folic acid nanoparticles (AF NPs) were homogeneous in size, stable for a long time in aqueous suspension without aggregation, and non-toxic. AF NPs were small enough to efficiently infiltrate tumors (<50 nm) and were specifically internalized by cancer cells through receptor-mediated endocytosis. After the intracellular absorption of NPs, alginate was deprotonated in the lysosomes and released 5ALA, which was converted to protoporphyrin IX (PpIX) through mitochondrial heme synthesis. Our study outcomes demonstrated that AF NPs were not degraded by enzymes or other external factors before reaching cancer cells, and fluorescent precursors were specifically and accurately delivered to cancer cells to generate fluorescence.

Evaluation of social cognitive measures in an Asian schizophrenia sample.

BACKGROUND: Converging evidence has indicated that deficits in social cognition may manifest as poor functioning; therefore, social cognition has emerged as an important research area and treatment target. However, few studies have examined the psychometrics of multiple social cognition measures in an Asian population. This study aims to evaluate the psychometrics of measures indexing the four core social cognition domains. METHODS: Schizophrenia outpatients (n = 116) and healthy controls (n = 73) completed a battery of nine social cognitive measures, twice, four weeks apart. Psychometric properties were examined via test-retest reliability, internal consistency, utility as a repeated measure, time administration, and tolerability. Logistic regression was performed to identify psychometrically sound tasks that best discriminated case-control status. PCA was conducted to explore social cognition dimensional structure. RESULTS: The Bell Lysaker Emotion Recognition Task (BLERT), Penn Emotion Recognition Task (ER40), and The Awareness of Social Inference Test, branch III (TASIT-3) showed strongest psychometrics. The Ambiguous Intentions and Hostility Questionnaire, Hostility Bias subscale (AIHQ-HB) showed slightly weaker properties, requiring further evaluation. The Hinting task, Mini Profile of Nonverbal Sensitivity (MiniPONS), Relationships Across Domains (RAD), Internal Personal and Situational Attributions Questionnaire (IPSAQ), and Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT) showed poorer psychometrics in our sample. PCA revealed a two-factor solution comprising social cognition skills and attributional style/bias. CONCLUSION: Here, we examined the psychometric properties of a comprehensive social cognition battery based on the SCOPE study in an Asian schizophrenia population. Continued evaluation and standardization of social cognitive measures are needed to refine our understanding of this construct in schizophrenia.
