Effects of the NeuroHAB Program on Low Back Pain and Oswestry Disability Index Scores: A Retrospective Wait-List Control Study.

Movement theory and the study of movement dysfunction mark a paradigm shift in the treatment of low back pain symptoms, the majority of which are mechanical in origin at the outset. Treating movement dysfunction centers around unified and consistent rehabilitation that defines proficient movement for the lumbopelvic spine. The purpose of this study is to document the improvement in pain and disability of 290 patients who underwent NeuroHAB Functional Movement Therapy to reverse their lumbopelvic movement dysfunction attributed to causing their back pain symptoms between 2019 and 2023. Oswestry Disability Index (ODI) scores were collected from each participant on three occasions: the first consultation, after a waiting period/pre-intervention, and after the eight-week intervention. A single-factor ANOVA of all three ODI data sets was conducted, along with supporting descriptive statistics. A post-hoc t-test pairwise comparison was conducted for accuracy. The average ODI 1 score (taken at the first consultation) was 15.26 ± 6.1% (CI: 14.3-16.2); ODI 2 (after a waiting period, before NeuroHAB) was 14.71 ± 6.0% (CI: 13.82-15.59); and ODI 3 (post-intervention) was 9.09 ± 8.6% (CI: 8.305-9.875). There was no significant change from ODI 1 to ODI 2 (between the consultation and waitlist control periods). However, a significant reduction between ODI 2 and ODI 3 was observed (pre- and post-intervention) (mean difference: 5.62, p ≤ 0.001), and a 40.41% reduction was observed between ODI 1 (the ODI score taken at the first consultation) and ODI 3 (the ODI score taken after NeuroHAB, post-intervention) (mean difference: 6.17, p ≤ 0.001). A 50% ODI reduction was reported in the "Crippled" category (mean difference 16.15, p ≤ 0.001). The inclusion of functional movement proficiency and stability in future guidelines is a necessary step towards meaningful improvement in epidemic levels of back pain-related clinical and economic morbidity.

Re-Purposing the Ordering of Routine Laboratory Tests in Hospitalized Medical Patients (RePORT): protocol for a multicenter stepped-wedge cluster randomised trial to evaluate the impact of a multicomponent intervention bundle to reduce laboratory test over-utilization

BackgroundLaboratory test overuse in hospitals is a form of healthcare waste that also harms patients. Developing and evaluating interventions to reduce this form of healthcare waste is critical. We detail the protocol for our study which aims to implement and evaluate the impact of an evidence-based, multicomponent intervention bundle on repetitive use of routine laboratory testing in hospitalized medical patients across adult hospitals in the province of British Columbia, Canada.MethodsWe have designed a stepped-wedge cluster randomized trial to assess the impact of a multicomponent intervention bundle across 16 hospitals in the province of British Columbia in Canada. We will use the Knowledge to Action cycle to guide implementation and the RE-AIM framework to guide evaluation of the intervention bundle. The primary outcome will be the number of routine laboratory tests ordered per patient-day in the intervention versus control periods. Secondary outcome measures will assess implementation fidelity, number of all common laboratory tests used, impact on healthcare costs, and safety outcomes. The study will include patients admitted to adult medical wards (internal medicine or family medicine) and healthcare providers working in these wards within the participating hospitals. After a baseline period of 24 weeks, we will conduct a 16-week pilot at one hospital site. A new cluster (containing approximately 2–3 hospitals) will receive the intervention every 12 weeks. We will evaluate the sustainability of implementation at 24 weeks post implementation of the final cluster. Using intention to treat, we will use generalized linear mixed models for analysis to evaluate the impact of the intervention on outcomes.DiscussionThe study builds upon a multicomponent intervention bundle that has previously demonstrated effectiveness. The elements of the intervention bundle are easily adaptable to other settings, facilitating future adoption in wider contexts. The study outputs are expected to have a positive impact as they will reduce usage of repetitive laboratory tests and provide empirically supported measures and tools for accomplishing this work.Trial RegistrationThis study was prospectively registered on April 8, 2024, via ClinicalTrials.gov Protocols Registration and Results System (NCT06359587). https://classic.clinicaltrials.gov/ct2/show/NCT06359587?term=NCT06359587&recrs=ab&draw=2&rank=1

Sample Size Calculation for an Individual Stepped-Wedge Randomized Trial.

In the individual stepped-wedge randomized trial (ISW-RT), subjects are allocated to sequences, each sequence being defined by a control period followed by an experimental period. The total follow-up time is the same for all sequences, but the duration of the control and experimental periods varies among sequences. To our knowledge, there is no validated sample size calculation formula for ISW-RTs unlike stepped-wedge cluster randomized trials (SW-CRTs). The objective of this study was to adapt the formula used for SW-CRTs to the case of individual randomization and to validate this adaptation using a Monte Carlo simulation study. The proposed sample size calculation formula for an ISW-RT design yielded satisfactory empirical power for most scenarios except scenarios with operating characteristic values near the boundary (i.e., smallest possible number of periods, very high or very low autocorrelation coefficient). Overall, the results provide useful insights into the sample size calculation for ISW-RTs.

Acute primary angle closure concurrent with coronavirus disease 2019 recurrence in Northern China: A retrospective multi-centre study

Aims and objectivesDuring the new coronavirus disease 2019 (COVID-19) outbreak period, there was increasing presentation in the number of patients with acute primary angle closure (APAC). This study aimed to report the occurrence of APAC during the COVID-19 post-restriction period and investigate the related characteristics of these patients with APAC. MethodsThis retrospective, multi-center study included consecutive patients seeking APAC treatment at two eye centers in China from December 7, 2022 to January 13, 2023 (post-restriction period) and from December 7, 2021 to January 13, 2022 (control period). Electronic medical records were reviewed, and ocular data of the affected eye(s) were analyzed for patients with unilateral or bilateral APAC. Information including COVID-19 related symptoms, medications used for COVID-19 infection, and living habits and emotions related to the COVID-19 outbreak during the post restriction period were collected using a questionnaire. ResultsOverall, 189 (219 APAC eyes) and 51 (54 APAC eyes) patients with APAC were identified during the post-restriction and control periods, respectively. The patients identified during the post-restriction period were younger (P = 0.043) and had a longer duration from symptoms to treatment (P = 0.039), shorter axial length (P = 0.002), larger pupil diameter (P = 0.004), larger vertical cup disc ratio (P = 0.004), poorer mean deviation values (P = 0.003), and more glaucomatous optic neuropathy diagnoses (P = 0.032) compared with the patients with APAC identified during the control period. Among 151 included patients with APAC who completed the questionnaires, 130 patients with APAC were diagnosed with concurrent COVID-19 infection, of which 54 (41.5 %) had coughing and/or vomiting as the main symptoms. Of these, 89.2 % spent 0 h per day on outdoor activity; 44.6 % drank more water than usual, with 14.6 % drinking more than twice the amount of water than usual; 91.5 % used antipyretics; and 20.0 % had mood swings, including anxiety, depression, and tension, during the concurrent COVID-19 infection. ConclusionIn our study, a significant increase in the number of patients presenting with APAC with certain characteristics was observed during the COVID-19 post-restriction period. And whether COVID-19 symptoms, such as coughing and vomiting, and behavioral and psychological changes caused by COVID-19 infection contributing to the concurrence of APAC and COVID-19 recurrence require further investigation.

Activity Levels in Seven Cats with Osteoarthritis Monitored by GPS Tracker Following Frunevetmab Injection

Abstract Objective The goal of the current pilot study was to use a commercially available accelerometer (Tractive GPS Tracker for Cats) in a setting evaluating the activity level of cats exhibiting different forms of osteoarthritis in their natural habitat before and after treatment with frunevetmab, using each individual cat as its own control. We hypothesized that treatment with frunevetmab would be associated with increased activity level. Methods Activity data, measured as minutes of active time per day via accelerometer worn on a collar, were obtained from seven employee-owned cats with radiographically confirmed evidence of osteoarthritis. Cats were randomly assigned to two different protocols in which treatment and no treatment (control) were reversed; that is, undergoing the control period prior to treatment with frunevetmab (“standard” control) versus first assessed without treatment (control period) followed by frunevetmab treatment after minimum 30-day washout period (“inverse” control period). Results Activity time, on average, was 30 minutes longer per day for frunevetmab versus control (p = 0.007). Conclusions Based on measurements obtained with piloted use of the Tractive, the activity level in osteoarthritic cats appeared greater when treated with frunevetmab compared to self-control without frunevetmab treatment (either pretreatment or following washout period). The small sample size here does warrant caution in interpreting results for a broader population.

Use of Azithromycin Attributable to Acute SARS-CoV-2 Infection.

In the early stages of the COVID-19 pandemic, preliminary results that later proved to be incorrect suggested the possible efficacy of anti-infective drugs such as azithromycin for the treatment of SARS-CoV-2 infection. These preliminary data may have influenced the prescription of azithromycin. However, no individual-level data linking the use of this antibiotic to acute SARS-CoV-2 infection are available. The present analysis aims to fill this gap. A retrospective population-based cohort design was used including patients diagnosed with SARS-CoV-2 infection in the period ranging from February 2020 to February 2022. The data source for antibiotic consumption was the drug database of outpatient prescriptions of Emilia-Romagna Region (Italy). Antibiotics were classified according to the Anatomical Therapeutic Chemical (ATC) classification system. Consumption rates and percentages of azithromycin DDDs (defined daily doses) during the acute phase of the infection were compared with a previous control period and with the post-acute phase. Analyses were stratified by four groups according to the prevalent virus variant at time of diagnosis. Comparing the previous control period with the acute phase of infections, the rates of azithromycin consumption (DDD per 1000 individuals per day) increased from 1.17 to 23.11, from 0.80 to 33.03, from 0.81 to 21.01, and from 1.02 to 9.76, in the pre-Alpha, Alpha, Delta, and Omicron periods, respectively. Similarly, the percentages of individuals receiving azithromycin, and the azithromycin DDDs percentages over total systemic antibiotics DDDs increased in acute phases of infection compared with control periods. The consumption rates and percentages returned to preinfection levels in the post-acute phase. In the study period, 12.9% of the use of azithromycin in the entire adult population of Emilia-Romagna was attributable to acute SARS-CoV-2 infection. Considering the low likelihood of bacterial coinfections, the increased azithromycin consumption in the acute phase of SARS-CoV-2 infection suggests inappropriate prescribing of this antibiotic.

Continuous Positive Airway Pressure versus Differential Lung Ventilation during One Lung Ventilation for Thoracic Surgery.

One lung ventilation (OLV) is a technique used during lung resection surgery to facilitate optimal surgical conditions. However, this may result in severe hypoxemia due to the right-to-left shunt created in the collapsed lung. Several techniques are used to overcome hypoxemia, one of which is continuous positive airway pressure (CPAP) to the non-dependent lung. Another technique is ventilating the non-dependent lung with a minimal volume, thus creating differential lung ventilation (DLV) or split lung ventilation (SLV). In this study, we compared the efficacy of CPAP to DLV during video-assisted thoracoscopic (VATS) lung resection. In this single-center randomized controlled, cross-over study, each patient acted as his control as well as the study. Patients crossed over from SLV to CPAP (or vice versa) with an interval period during which only OLV was used (control period). The primary objective of the study was to observe the changes in oxygenation, ventilation, and the surgeons' perception of the surgical field using CPAP or SLV to the non-ventilated lung during the period of OLV in patients undergoing thoracic surgery. The study revealed that oxygenation was significantly better when using SLV to the non-ventilated lung during the period of OLV (P = 0.03). However, the surgeon found a significantly better surgical field when applying CPAP to the surgical field. The study showed that using SLV to the non-ventilated lung during the period of OLV was superior in terms of oxygenation, although it interfered more with the surgical field.

Effect of a 4-Week Telerehabilitation Program for People With Post-COVID Syndrome on Physical Function and Symptoms: Protocol for a Randomized Controlled Trial.

COVID-19 has led to significant morbidity and mortality globally. Post-COVID sequelae can persist beyond the acute and subacute phases of infection, often termed post-COVID syndrome (PCS). There is limited evidence on the appropriate rehabilitation for people with PCS. The aim of this study is to evaluate the effect on exercise capacity, symptoms, cognition, anxiety, depression, health-related quality of life, and fatigue of a 4-week, twice-weekly supervised pulmonary telerehabilitation program compared with usual medical care for people with PCS with persistent respiratory symptoms. The study will be a multi-site randomized controlled trial with assessor blinding. Participants with confirmed previous COVID-19 infection and persistent respiratory symptoms who attend a post-COVID respiratory clinic will be randomized 1:1 to either an intervention group of 4weeks, twice-weekly pulmonary telerehabilitation or a control group of usual medical care. Participants in the control group will be invited to cross-over into the intervention group after the week 4 assessment. Primary outcome: exercise capacity measured by the 1-minute sit-to-stand test. Secondary outcomes: 5 repetition sit-to-stand test; Montreal Cognitive Assessment; COVID-19 Yorkshire Rehabilitation Scale; Chronic Obstructive Pulmonary Disease Assessment Test; 36-Item Short-Form Health Survey; Hospital Anxiety and Depression Scale; Fatigue Severity Scale; and the Kessler Psychological Distress Scale. Outcomes will be collected at baseline, after 4-weeks intervention or control period, after intervention in the cross-over group, and at 12-month follow-up. Research into effective rehabilitation programs is crucial given the substantial morbidity associated with PCS and the lack of long-term data for COVID-19 recovery. A short-duration pulmonary telerehabilitation program, if effective compared with usual care, could inform practice guidelines and direct future clinical trials for the benefit of individuals with persistent respiratory symptoms post-COVID.

Markers and Predictors of Proliferative Vitreoretinopathy in Open Eye Injury in an Experiment

The objective of the study: to analyze characteristics of a standardized model of type B gunshot open global injury (open injury without intraocular foreign body).Methods: The experiment was carried out on 36 rabbits (71 eyes). Simulation of type B gunshot open global injury (GOEI) was accomplished using pump equipment. The complex of modern standard and high­technology diagnostic methods to study characteristics of type B GOEI in the control period was performed. Biomicroscopy, ophthalmoscopy, optical coherence tomography, electroretinography, ultrasound examination, MRI, enzyme multiplied immunoassay to determine vitreous fibronectin, and pathomorphological study of the eye globe were carried out. Non­parametric statistical methods of data analysis were used.Results: The above diagnostic methods being used, the GOEI experimental model characteristics were determined, including proliferative vitreoretinopathy (PVR) i.e.incidence rate and dynamics.Conclusion. High reproducibility (77–100 %) of microlevel signs of type B GOEI experimental model was demonstrated, that evidenced standardization of the developed model. The viability of the use of hyphema and hemophthalmia as the PVR and GOEI predictors was justified on the basis of correlation analysis in experiment. The analysis of proliferative signs being made when using different study methods (pathomorphological, indirect ophthalmoscopy, optical coherence tomography, ultrasound examination and MRI) proved their application as PVR markers possible. The interchangeability of the study methods used for PVR diagnosis was also justified.

Influenza Infection and Acute Myocardial Infarction

BackgroundAcute respiratory infections can trigger acute myocardial infarction. We aimed to quantify the association between laboratory-confirmed influenza infection and acute myocardial infarction, particularly in patients with and without known coronary artery disease.MethodsThis observational, registry-based, self-controlled case series study evaluated the association between laboratory-confirmed influenza infection and occurrence of acute myocardial infarction. Laboratory records on respiratory virus polymerase chain reaction (PCR) testing from 16 laboratories across the Netherlands were linked to national mortality, hospitalization, medication, and administrative registries. Influenza infection was defined as a positive PCR test result. Acute myocardial infarction was defined as a registered diagnostic code for either acute myocardial infarction hospitalization or death. Using a self-controlled case series method, we then compared the incidence of acute myocardial infarction during the risk period (days 1 to 7 after influenza infection) versus the control period (1 year before and 51 weeks after the risk period).ResultsBetween 2008 and 2019, we identified 158,777 PCR tests for influenza in the study population; 26,221 were positive for influenza, constituting 23,405 unique influenza illness episodes. A total of 406 episodes were identified with acute myocardial infarction occurring within 1 year before and 1 year after confirmed influenza infection and were included in analysis. Twenty-five cases of acute myocardial infarction occurred during the risk period versus 394 during the control period. The adjusted relative incidence of acute myocardial infarction during the risk period compared with the control period was 6.16 (95% confidence interval [CI], 4.11 to 9.24). The relative incidence of acute myocardial infarction in individuals without prior hospitalization for coronary artery disease was 16.60 (95% CI, 10.45 to 26.37) compared with 1.43 (95% CI, 0.53 to 3.84) for those with prior admission for coronary artery disease.ConclusionsInfluenza infection was associated with an increased risk of acute myocardial infarction, especially in individuals without a prior hospitalization for coronary artery disease.

OUR EXPERIENCE IN SURGICAL TREATMENT OF MUCOSAL HYPERTROPHY OF TORI TUBARII

Puprose. Evaluation of the effectiveness of surgical treatment of mucous hypertrophy of tori tubarii by submucosal tissue destruction using Ho:YAG laser radiation. Materials and methods. The study involved 48 adult patients with symptoms of Eustachian tube dysfunction. The patency of the auditory tube was assessed by standard tests, the ETDQ 7 questionnaire, tympanometry, pure tone threshold audiometry, and endoscopic video recording of the results were performed. Surgical intervention was carried out by forming under the influence of pulsed radiation from a Ho:YAG laser with a frequency of 10 Hz and a pulse energy of 2 J, 4–6 tunnels with a depth of 5–7 mm in the hypertrophied mucous membrane of the torui tubarii along the posteromedial surface and 2 tunnels up to 3 mm up and down from the pharyngeal mouth of the auditory tube. The control periods after surgery were 1, 3 and 6 months. Results. A significant improvement in the results of the auditory tube according to ETDQ-7 was noted by 3 months after surgery in 71% of patients and in 84% by 6 months. By 6 months after surgery, type C tympanometry and clinically significant conductive hearing loss persisted in 8 and 5% of patients, respectively. The subjective feeling of fully performing the Valsalva test improved in 58% after 3 months and in 82% by the 6th month, and the Toynbee test in 42% and 64% in the 3rd and 6th months, respectively. In 16% of patients, despite a visual decrease in mucosal hypertrophy during endoscopic examination, signs of dysfunction remained according to ETDQ 7. There were no complications after surgical treatment during 6 months of observation. Conclusion. The use of endoscopic diagnosis of the nasopharynx in patients with signs of dysfunction of the auditory tubes in combination with functional tests and the ETDQ-7 questionnaire allows to determine the indications for the surgical treatment of hypertrophy of the mucous membrane of the tori tubarii using the Ho:YAG laser, the effectiveness of which in our study was 84%.

Translational artificial intelligence-led optimization and realization of estimated discharge with a supportive weekend interprofessional flow team (TAILORED-SWIFT).

Weekend discharges occur less frequently than discharges on weekdays, contributing to hospital congestion. Artificial intelligence algorithms have previously been derived to predict which patients are nearing discharge based upon ward round notes. In this implementation study, such an artificial intelligence algorithm was coupled with a multidisciplinary discharge facilitation team on weekend shifts. This approach was implemented in a tertiary hospital, and then compared to a historical cohort from the same time the previous year. There were 3990 patients included in the study. There was a significant increase in the proportion of inpatients who received weekend discharges in the intervention group compared to the control group (median 18%, IQR 18-20%, vs median 14%, IQR 12% to 17%, P = 0.031). There was a corresponding higher absolute number of weekend discharges during the intervention period compared to the control period (P = 0.025). The studied intervention was associated with an increase in weekend discharges and economic analyses support this approach as being cost-effective. Further studies are required to examine the generalizability of this approach to other centers.

Hydroxychloroquine Dose and Hospitalizations for Active Lupus.

We sought to determine the impact of hydroxychloroquine (HCQ) dose on the risk of hospitalizations for systemic lupus erythematosus (SLE). We conducted a case-crossover study within an academic health system, including patients with SLE who used HCQ and had ≥1 hospitalization for active SLE between January 2011 and December 2021. Case periods ended in hospitalization for SLE, whereas control periods did not. The exposures were the average weight-based HCQ dose, categorized as ≤5 or >5 mg/kg/day, and non-weight-based HCQ dose, categorized as <400 or 400 mg/day, assessed during each six-month case or control period. Odds ratios (ORs) were calculated using conditional logistic regression and adjusted for prior disease activity, kidney function, glucocorticoid use, and other immunosuppressant use. Of 2,974 patients with SLE who used HCQ (mean age 36.5 years; 92% female), 584 had ≥1 hospitalization with primary discharge diagnosis of SLE. Of these, 122 had ≥1 hospitalization for active SLE while using HCQ and had ≥1 control period with HCQ use during the study period. Lower HCQ weight-based dose (≤5 vs >5 mg/kg/day) and non-weight-based dose (<400 vs 400 mg/day) were each associated with increased hospitalizations for active SLE (adjusted OR 4.20, 95% confidence interval [CI] 1.45-12.19, and adjusted OR 3.39, 95% CI 1.31-8.81). The use of lower doses of HCQ was associated with an increased risk of hospitalizations for active SLE. Although the long-term risk of HCQ retinopathy must be acknowledged, this must be balanced with the short-term and cumulative risks of increased SLE activity.

Time-optimal state transfer for an open qubit

Finding minimal time and establishing the structure of the corresponding optimal controls which can transfer a given initial state of a quantum system into a given target state is a key problem of quantum control. In this work, this problem is solved for a basic component of various quantum technology processes—a qubit interacting with the environment and experiencing an arbitrary time-dependent coherent driving. We rigorously derive both upper and lower estimates for the minimal steering time. Surprisingly, we discover that the optimal controls have a very special form—they consist of two impulses, at the beginning and at the end of the control period, which can be assisted by a smooth time-dependent control in between. Moreover, an important for practical applications explicit almost optimal state transfer protocol is provided which only consists of four impulses and gives an almost optimal time of motion. The results can be directly applied to a variety of experimental situations for estimation of the ultimate limits of state control for quantum technologies.

Intelligent extraction of reservoir dispatching information integrating large language model and structured prompts

Reservoir dispatching regulations are a crucial basis for reservoir operation, and using information extraction technology to extract entities and relationships from heterogeneous texts to form triples can provide structured knowledge support for professionals in making dispatch decisions and intelligent recommendations. Current information extraction technologies require manual data labeling, consuming a significant amount of time. As the number of dispatch rules increases, this method cannot meet the need for timely generation of dispatch plans during emergency flood control periods. Furthermore, utilizing natural language prompts to guide large language models in completing reservoir dispatch extraction tasks also presents challenges of cognitive load and instability in model output. Therefore, this paper proposes an entity and relationship extraction method for reservoir dispatch based on structured prompt language. Initially, a variety of labels are refined according to the extraction tasks, then organized and defined using the Backus–Naur Form (BNF) to create a structured format, thus better guiding large language models in the extraction work. Moreover, an AI agent based on this method has been developed to facilitate operation by dispatch professionals, allowing for the quick acquisition of structured data. Experimental verification has shown that, in the task of extracting entities and relationships for reservoir dispatch, this AI agent not only effectively reduces cognitive burden and the impact of instability in model output but also demonstrates high extraction performance (with F1 scores for extracting entities and relationships both above 80%), offering a new solution approach for knowledge extraction tasks in other water resource fields.

Plastic and Reconstructive Surgery Resident Indigent Care Clinic Optimization by Improving "No-Show" Rates.

Absenteeism among clinical patients is a significant source of inefficiency in the modern American health care system. Routine absenteeism limits access to care for indigent patients, thus providing additional strain on the health care system and timely administration of care.This quality improvement project set out to quantify, understand, and potentially reduce patient absenteeism in our weekly plastic and reconstructive surgery resident indigent care clinic. One year prior to our study was retrospectively reviewed to determine a baseline rate of absenteeism (no shows). The daily and monthly no-show percentages were calculated. Then, three consecutive 2-month Plan, Do, Study, Act (PDSA) cycles were performed and data were recorded.The initial year analysis demonstrated an average no-show rate of 25%. The first PDSA cycle attempted to ascertain factors contributing to absenteeism and to get patients rescheduled. The rate of clinical absenteeism was 27% over this period compared with a rate of 18% in the control period. During this period, we discovered a limitation of our institution's electronic medical record (EMR). Rescheduled patients were removed from the original schedule and were not counted as a missed appointment even though the opportunity for care was missed. The second PDSA cycle attempted to collect raw data while trying to understand the EMR error and rescheduling process. During this period, there was a 33% no-show rate compared with 27% in the control period. The third PDSA cycle attempted again to establish factors contributing to clinical absenteeism with a better understanding of the limitations of our EMR. A 33% no-show rate during this cycle was recorded compared with 22% in the control period. After three PDSA cycles were completed, our clinic had an average no-show rate of 31% compared with 25% during the same months in the previous year.This project brought to realization that our data were initially skewed by our ignorance of an EMR flaw that did not track patients who either canceled or rescheduled their appointments. We also learned that there is a certain subset of patients who are not able to be contacted and who do not follow up.

Impact of COVID-19 Restrictions on Incidence of Enteropathogenic Bacteria, Virus, and Parasites in Denmark: A National, Register-Based Study.

Diarrheal diseases caused by enteric pathogens are a significant public health concern. It is widely considered that close contact between persons, poor hygiene, and consumption of contaminated food are the primary causes of gastroenteritis. Clinical microbiology laboratory observations indicate that the incidence of enteropathogenic microorganisms may have been reduced in Denmark during the COVID-19 pandemic. All Departments of Clinical Microbiology in Denmark provided data on the monthly incidence of Salmonella spp., Escherichia coli, Campylobacter spp., Clostridioides difficile, Norovirus GI+GII, Giardia duodenalis, and Cryptosporidium from March 2018 to February 2021. The data were divided into three periods as follows: Control Period 1 (March 2018 to February 2019); Control Period 2 (March 2019 to February 2020); and the Restriction (pandemic) Period (March 2020 to February 2021). The incidences of pathogenic Salmonella spp.-, Escherichia coli-, and Campylobacter spp.-positive samples decreased by 57.3%, 48.1%, and 32.9%, respectively, during the restriction period. No decrease in C. difficile was observed. Norovirus GI+GII-positive samples decreased by 85.6%. Giardia duodenalis-positive samples decreased by 66.2%. Cryptosporidium species decreased by 59.6%. This study demonstrates a clear decrease in the incidence of enteropathogenic bacteria (except for C. difficile), viruses, and parasites during the SARS-CoV-2 restriction period in Denmark.

Implementation of an optimised tele-medicine platform for stroke in South Australia improves patient care.

Patients with a large vessel occlusion require a transfer from a primary stroke centre to access thrombectomy, often over significant distances in regional areas. We sought to optimise stroke care access in the regional South Australian Tele-Strokeservice (SATS) to improve patient access to thrombectomy. We undertook a 24-month interventional historically controlled cohort study comparing acute stroke care metrics in the SATS. This consisted of a 12-month control period and a 12-month intervention monitoring period. The study intervention considered of an education package provided to the regional hospitals, a stroke neurologist roster to receive consultations and the intervention of a centralised tele-stroke system to provide treatment advice and organise patient transfers where needed. The SATS services 61 rural hospitals in South Australia, and Alice Springs in the Northern Territory. Suspected acute stroke patients presenting to the participating regional hospitals in SATS network where a telehealth consultation took place. Over the study period, there were 919 patient referrals, with 449 consultations in the pre-intervention phase and 470 in the post-intervention phase. Demographic features in both epochs were similar. The post-intervention phase was associated with shorter door-to-scan time (35 min, IQR: 18,70; vs. 49 min, IQR:25,102, p < 0.0001), faster door-to-thrombolysis time (58 min, IQR: 39,91, vs.83 min, IQR: 55,100, p = 0.0324) and a higher portion of patients treated with thrombectomy (54, 11.5% vs. 26, 5.8%, p = 0.002). An optimised implementation of a streamlined telehealth platform with ongoing education and feedback to referring sites was associated with improved stroke workflow metrics and higher thrombectomy rates.

Least Squares, Simple Linear Regression, and Pearson Correlation Analysis between the Lactation Milk Yield of Norduz Ewes and Their Lambs’ Live Weight

This study aimed to determine the lactation milk yield of Norduz ewes and to determine the effects of milk yield on their lambs’ growth and development characteristics. Additionally, the correlations between the sheep’s milk yield, lambs’ live weight, and affecting factors were determined. The study was conducted at the Van University of Yüzüncü Yıl Agricultural Research Center. In the study, 61 Norduz ewes and 66 male and female lambs they bore were included. The sheep were milked at 30-day intervals until the 180th day. Similarly, the lambs were weighed at 30-day intervals from birth to 180th day. The means and standard errors of the milk yields were obtained on the 30, 60, 90, 120, 150th, and 180th days of milking. The live weight means and standard errors of the lambs on the 30th, 60th, 90th, 120th, 150th, and 180th days are given. According to the GLM analysis results, sex significantly influenced lactation length (p&amp;lt;0.05), and there was a difference in favor of female lambs. The impact of dam age was notably significant on live weight at days 60 and 90 (p&amp;lt;0.05). Additionally, birth type significantly affected live weight at day 30 and 60 (p&amp;lt;0.001), as well as at day 90 (p&amp;lt;0.01). Regarding the linear relationship between dam weight and live weight, a significant effect was observed at day 30 (p&amp;lt;0.001), day 60 (p&amp;lt;0.01), and day 90 (p&amp;lt;0.05). Notably, the linear effects of lamb birth weight on live weight remained significant across all control periods (p&amp;lt;0.001).

Bloom's taxonomy-Can evidence-based teaching improve junior medical officers' knowledge of the mental health and guardianship acts?

To determine whether a brief educational intervention for Junior Medical Officers (JMOs), using teaching methods aimed at achieving higher outcomes on Bloom's Taxonomy, significantly improved participant confidence and knowledge in decision making about restrictive care. JMOs received a teaching session on restrictive medical and mental health care. Groups were randomly assigned to either sessions including a component of modern pedagogical interventions (Think-Pair-Share and SNAPPS), or sessions including a control period focusing on reviewing a condensed summary of relevant information. Pre- and post-intervention measures were recorded for subjective self-ratings of confidence and scores on standardized clinically relevant extended matching questions (EMQs). There was no difference in subjective confidence improvement between groups; however, the group receiving the modern pedagogical intervention demonstrated significantly greater objective performance on knowledge-based EMQs. A brief modern pedagogical intervention using interactive teaching methods shows promise for improving knowledge of restrictive care and the Mental Health and Guardianship Acts. In the control group, similarly increased confidence in knowledge did not equate to increased competence on a knowledge assessment. Refurbishing educational interventions presents opportunities for improving clinical outcomes and engaging junior doctors in psychiatry.
