Abstract
The Chilean north Patagonian lakes are characterized by their marked oligotrophic or oligomesotrophic status and low abundance of zooplankton species; many of the lakes with oligomesotrophic status are associated with human intervention due to towns on their shores. The aim of the present study was to determine the relations between spectral properties (LANDSAT OLI), chlorophyll and plankton abundances in two north Patagonian lakes: Villarrica, which has two towns on its shores, and Lake Caburgua, which has native forest on its shores. The results revealed that Lake Villarrica has high reflectance in the near infrared, red and green bands, high concentrations of chlorophyll a, the absence of mixotrophic protozoa, and a high abundance of bacterial and plankton, mainly phytoplankton (Chlophyceae and diatoms) and zooplankton. Lake Caburgua, on the other hand, has low reflectance in the same bands, and low chlorophyll concentrations, low bacterial and zooplankton abundances, with the exception of high mixotrophic ciliates and small phytoplankton, and Volvox colonies. The obtained results agree with limnological observations on both lakes, and observations agrees with similar observations of the spectral properties of glacial north Patagonian lakes and of the zooplankton community, and in this scenario, the use of remote-sensing techniques would be a good tool to predict the plankton community in Patagonian lakes.

Published: November 2022

Objectives: Adolescence is a critical phase of life, involving both risks and opportunities. Preventive health services in this phase contribute to the development of adolescents’ models for adulthood. The current study aimed to illuminate adolescents’ experiences regarding health education through a patient visit in a hospital, which provides a more informal learning environment than classroom instruction. Design: Qualitative one group experimental design. Setting: Participants were 16 high school students of a medium-level socio-economic status in Turkey, some of whom smoked cigarettes. Method: We visited patients in the pulmonology inpatient unit with the students. Data were collected through interviews, video recordings and field notes. Data were analyses using content analysis in which coding schemes are developed directly from the textual data to focus in on students’ health beliefs. Results: Findings revealed that the students who interacted face-to-face with patients and listened to their reflections on their illness and life experienced changes in their health beliefs. The visit provided moral support for the patients as well. Conclusion: Results indicate that such hospital patient visits offer significant opportunities for health education.

Published: November 2022

Background: Patient with schizophrenia are significantly more likely to be violent than general population; and the consequences of this violence risk are often very serious for the patients, their caregivers, and the entire community. Aim: To assess the risk of violence in patients with schizophrenia and its correlation with severity of symptoms and cognitive functions. Methods: A cross-sectional comparative study conducted in Okasha institute of psychiatry including 50 patients with schizophrenia compared to 50 healthy control group regarding violence risk as assessed by Historical, Clinical, and Risk Management-20 (HCR-20), case group was assessed using Structured Clinical Interview for DSM-IV (SCID-I), Positive and Negative Syndrome Scale (PANSS), cognitive functions were assessed by Wechsler Adult Intelligence Scale (WAIS), Trail Making Test (TMT) Part A and B, the Wisconsin Card Sorting Test (WCST), and the Wechsler Memory Scale (WMS). Results: There was a statistically significant difference between case and control groups regarding risk of violence where 58% of the case group were found to have risk of violence compared to only 18% in the control group. There was a significant correlation between this risk of violence and period of untreated psychosis, no of episodes, and history of substance use; also was significantly correlated with PANSS and Wisconsin card sorting test subscales. Regarding logistic regression analysis for factors affecting violence risk; total PANSS score and history of substance use were significant independent factors that increase violence risk. Conclusion: Violence risk in patient with schizophrenia is a cardinal factor that may affect life of the patients, their family, and society; this risk can be affected by different factors including severity of symptoms, no of episodes, history of substance use, and cognitive function of the patients.

Objective/Research Question: This article examines the racial equity of transfer incentive policies by responding to the research question: How do students of differing races and ethnicities vary in their opportunity to benefit from transfer incentive policies? Methods: We utilized a mixed-methods approach, grounded in Critical Race Theory (CRT). This study included an analysis of state policies’ components and mechanisms to consider whether they are grounded in racially unjust assumptions. The critical policy analysis is combined with a QuantCrit analysis of national data from the Beginning Postsecondary Students Longitudinal Study (BPS) to understand how identified aspects of the policies would affect students of differing races/ethnicities. Results: Our critical policy discourse analysis demonstrates that states’ transfer incentive policies could foster racial inequity through the requirements students must meet (e.g., full-time status, being under the age of 24) and assumptions about what students may know or need regarding transfer. The QuantCrit analysis revealed that many transfer incentive requirements from the policy analysis findings would have a disproportionately negative effect on racially minoritized students’ transfer eligibility. Together, findings and results illustrate how transfer incentives can contribute to educational inequity for racially minoritized students via color-evasive and meritocratic policies. Conclusions/Contributions: Implications include policy reform needed for the development of incentives aligned with closing the racial transfer gap and focused on incentivizing 2- and 4-year institutions in improving the transfer rates of racially minoritized students.
The impact of intrathecal baclofen on the ability to walk: A systematic review
Authors: Lee Hui Ping , Win Thuya , Balakrishnan Sudha 
Published: November 2022

Objective Intrathecal baclofen (ITB) is an effective treatment for lower limb spasticity. In ambulatory patients with spasticity, there is a justifiable concern that ITB treatment may compromise ambulatory function by reducing the heightened muscle tone, thereby unmasking underlying muscle weakness. ITB is hence offered with reservation in ambulant patients. In this article, we review the literature surrounding the effect of ITB therapy on ambulatory function in patients with concurrent spasticity and discuss the key findings. Data sources A literature search of ProQuest Medline and EBSCO CINAHL databases was performed. Review method Inclusion criteria included (a) studies reporting the effect of ITB in adult ambulatory patients; (b) studies with an intervention of screening test trial via either bolus injections or continuous infusion tests; and (c) studies with an intervention of ITB pump implantation. Seventeen eligible studies were identified and two authors independently assessed the study quality using the risk of bias in nonrandomised studies of interventions tool (ROBINS-I). Results Seventeen studies were included, with a total of 534 participants. Most of the patients remain ambulatory after ITB treatment, accompanied by improvements in gait speed and reduction in spasticity. Conclusion ITB therapy when administered in carefully selected ambulatory patients with spasticity is not associated with loss of ambulatory function.

Published: November 2022

Purpose Perceived Social Support (PSS) can impact breastfeeding behaviors, and a lack of PSS potentially contributes to disparities in breastfeeding rates for African American women (AA). Objectives were to describe PSS at two timepoints and test associations between PSS and breastfeeding intensity for AA. Methods Data are from a feasibility trial of breastfeeding support among AA. The Hughes Breastfeeding Support Scale was used to measure PSS (Emotional, Informational, Tangible; total range = 30–120) in pregnancy (T1, n = 32) and early postpartum (T2, n = 31). Scale means were compared with t-tests. Associations between PSS at T1 and breastfeeding intensity (ie, quantitative measure of breastfeeding) were assessed with linear regression. Results Total PSS (mean ± SE) was high at both time points (T1 = 90.5 ± 4.8; T2 = 92.8 ± 3.1). At T2, older participants or those living with a partner had higher total PSS scores compared to those younger or living alone. Emotional PSS was significantly higher at T2 than T1 with no differences in tangible or informational PSS over time. Mixed-feeding, exclusive breastfeeding, and exclusive formula feeding was distributed at 39%, 32%, and 29%, respectively. Total PSS was not associated with breastfeeding intensity. Conclusion Women reported high levels of social support, and emotional PSS increased over time in this small sample of AA. PSS and sources of PSS are understudied, especially among AA, and future studies should explore quantitative methods to assess PSS. The results of such assessments can then be used to design breastfeeding support interventions.

Purpose To evaluate clinical outcomes between hybrid closed wedge high tibial osteotomy (HCWHTO) and total knee arthroplasty (TKA) for advanced medial compartmental osteoarthritis of the knee (advanced knee OA). Methods In more than grade 3 OA based on the Kellgren-Lawrence classification, when patients’ age was less than 60 years or activity level was more than level 5 based on the UCLA activity score, 22 knees (18 patients) underwent HCWHTO. The other 22 knees (18 patients) that underwent TKA were evaluated retrospectively. Muscle strength was evaluated preoperatively and at 1 year postoperatively. The visual analogue scale (VAS) and Japanese version of the Knee injury and Osteoarthritis Outcome Score (J-KOOS) were used to evaluate clinical outcomes preoperatively and at a mean 66-months follow-up. Results All postoperative muscle strength measures improved to preoperative equivalent levels in the HCWHTO group; they were significantly higher in the HCWHTO group than in the TKA group ( p < .05). The VAS score and total J-KOOS significantly improved in both groups (HCWHTO, p = .001; TKA, p = .040); there were no significant differences in the scores between the groups at the final follow-up. Hybrid closed wedge HTO significantly improved the activities of daily living and sport/recreation scores, whereas TKA did not at the final follow-up. Conclusions In advanced knee OA, HCWHTO led to improved muscle strength, and its midterm clinical outcomes were equivalent to those of TKA. To postpone or even to avoid TKA, HCWHTO is considered an appropriate treatment for young and high-activity patients with advanced knee OA. Level of Evidence Therapeutic Level III

Objective To examine levator veli palatini muscle composition in patients with nonsyndromic cleft palate and investigate the impact of Veau class. Design Prospective cohort study. Setting Tertiary care academic hospital. Patients/Participants Thirteen patients with nonsyndromic cleft palate were recruited. Interventions During primary palatoplasty, a sample of levator veli palatini muscle was excised and prepared for histological analysis. Main Outcome Measures Fat and collagen content were determined utilizing Oil Red and Sirius red stains, respectively, while muscle fiber cross-sectional areas were calculated from H&E-stained samples, with analysis using histomorphometric methods. Immunofluorescent staining of myosin heavy chain isoforms was performed. Results Patients underwent repair at 10.8 months of age (interquartile range [IQR] 10.2-12.9). Fat content of the levator veli palatini muscle was low in both groups, ranging from 0% to 5.2%. Collagen content ranged from 8.5% to 39.8%; neither fat nor collagen content showed an association with Veau classes. Mean muscle fiber cross-sectional area decreased with increasing Veau class, from 808 µm2 (range 692-995 µm2) in Veau II to 651 µm2 (range 232-750 µm2) in Veau III ( P = .02). There was also a nonsignificant decrease in proportion of type I muscle fibers with increasing Veau class (44.3% [range 31.4%-84.4%] in Veau II vs 35.3% [range 17.4%-61.3%] in Veau III). Conclusions Muscle fiber area in levator veli palatini muscles decreases in Veau III clefts in comparison to Veau II. The impact of these differences in velopharyngeal dysfunction requires further analysis of a larger cohort.

Introduction: Food-borne disease is a major health problem especially in low-income countries like Ethiopia. This study aimed to assess the knowledge and practice of food handlers at student cafeteria of Kotebe Metropolitan University. Methods: A cross-sectional study design was conducted among 68 food handlers in student cafeteria of Kotebe Metropolitan University from May 30, 2018 to October 30, 2019. A structured questionnaire was used via face-to-face interviews to assess food handler’s knowledge of food safety and practices food safety. Data were analyzed using Statistical Package for the Social Sciences window version 20 and presented in the form of frequency tables, percentages, and graphs. The association was tested using Pearson’s chi-square, where P-value (<.05) was considered statistically significant. Results: The result showed that food handlers had good knowledge of food safety and good practice of food safety measured by the passing score of 40 (57.94%) and 48 (70.6%), respectively. Almost all food handlers were aware of the crucial role of knowledge of food safety and food safety practices in the student cafeteria. Accordingly, results of this work revealed that 67 (98.5%), 60 (88.2%), 65 (95.6%), and 56 (82.4%) of the subjects had food safety knowledge, always wash vegetables and fruits, had hand washing facilities with a supply of hot water, soap, and hand drying towel, had a hair mask or cloth during food preparation, and wore safety cloth during food preparation, respectively. Conclusion: The findings revealed significant relationship between food safety practices of food handlers and level of education, specifically regarding access to hand washing facilities, hand washing after a break and in the toilet, changing gloves between raw and ready-to-eat food, and drying and cleaning hands before handling food ( P < .05). Additionally, Kotebe Metropolitan University should design food handling and safety guidelines and offer specific training for food handling workers.

Published: November 2022

Objective We describe our approach to surveillance of reportable safety events captured in hospital data including free-text clinical notes. We hypothesize that a) some patient safety events are documented only in the clinical notes and not in any other accessible source; and b) large-scale abstraction of event data from clinical notes is feasible. Materials and Methods We use regular expressions to generate a training data set for a machine learning model and apply this model to the full set of clinical notes and conduct further review to identify safety events of interest. We demonstrate this approach on peripheral intravenous (PIV) infiltrations and extravasations (PIVIEs). Results During Phase 1, we collected 21,362 clinical notes, of which 2342 were reviewed. We identified 125 PIV events, of which 44 cases (35%) were not captured by other patient safety systems. During Phase 2, we collected 60,735 clinical notes and identified 440 infiltrate events. Our classifier demonstrated accuracy above 90%. Conclusion Our method to identify safety events from the free text of clinical documentation offers a feasible and scalable approach to enhance existing patient safety systems. Expert reviewers, using a machine learning model, can conduct routine surveillance of patient safety events.

Objective: Virtual reality can be applied preoperatively by surgeons to gain precise insights into a patient’s anatomy for planning minimally invasive coronary artery bypass grafting (CABG) with in situ arterial grafts. This study aimed to examine virtual reality simulation for minimally invasive CABG with in situ arterial grafts. Methods: Preoperative stereolithographic files in 35 in situ arterial grafts were converted using 320-slice computed tomography and workstation. The accurate length and direction of each graft were confirmed through virtual reality glasses. The simulation of graft designs was performed by using an immersive virtual reality platform. Results: The mean harvested lengths of in situ left internal thoracic artery ( n = 17), right internal thoracic artery ( n = 12), and gastroepiploic artery ( n = 6) grafts predicted by virtual reality simulation were 21.4 ± 3.4 cm, 21.2 ± 3.6 cm, and 22.8 ± 4.8 cm. The required lengths of these grafts predicted by virtual reality simulation were 15.8 ± 2.3 cm, 16.4 ± 2.1 cm, and 14.5 ± 4.4 cm. Minimally invasive CABG using virtual reality simulation was completed in 17 patients, of whom 16 patients underwent aortic no-touch total arterial CABG. The surgical strategy was adjusted in 11.8% of the cases due to the 3-dimensional virtual reality–based anatomy evaluation. The early mortality and morbidity were 0%, and the patency of the graft was 100%. The median time to return to full physical activity was 7.1 days. Conclusions: This study demonstrated the successful development and clinical application of the first dedicated virtual reality platform for planning aortic no-touch total arterial minimally invasive CABG. Virtual reality simulation can allow the accurate preoperative understanding of anatomy and appropriate planning of the graft design with acceptable postoperative outcomes.

Authors: Schroeder Michael J. , Reddy Nihaal , Rust Andrew , O’Brien Andrew L. , Jain Sonu A. 
Published: November 2022

Background: Endoscopic and open carpal tunnel releases (ECTR and OCTR) are safe and effective operations. We compared the approaches in terms of postoperative opioid refills and occupational therapy (OT) referrals. Methods: We conducted a retrospective study of patients with carpal tunnel syndrome (CTS) treated with ECTR or OCTR. Patients with isolated idiopathic CTS were included; patients undergoing simultaneous bilateral carpal tunnel release (CTR), revision CTR, and additional procedures at time of CTR were excluded. Outcomes included number of patients requiring an opioid refill and/or an OT referral within 6 months of surgery. Results: A total of 1125 patients met inclusion criteria. Endoscopic release was performed in 634 (56%) cases and open release in 491 (44%). Unadjusted analysis revealed no difference in number of patients requiring refills (6.0% vs 7.1%, P = .44), mean number of refills among those requiring one (1.29 vs 1.23, P = .69), total oral morphine equivalents (45.1 vs 44.7, P = .84), number of patients calling regarding pain (12.8% vs 14.7%, P = .36), OT referrals (12.1% vs 11.4%, P = .71), or average number of OT visits (4.5 vs 4.2, P = .74) for endoscopic and open techniques, respectively. Adjusted analysis revealed lower age, lower body mass index, and history of muscle relaxant as predictors of opioid refills, and in contrast to the unadjusted analysis, operating surgeon and surgical technique were predictors of referral to OT. Conclusion: Endoscopic CTR and OCTR did not differ in terms of unadjusted postoperative patient calls for pain, number of opioid refills, or OT referrals. After correcting for individual surgeon practice, endoscopic was associated with decreased odds of requiring postoperative OT.
