Medium- to Long-term Outcomes of Fasciotomy for Chronic Exertional Compartment Syndrome: A 6-Year Mean Follow-up Study.

BACKGROUND: Operative treatment of chronic exertional compartment syndrome (CECS) with fasciotomy is effective for symptomatic resolution, but outcomes at medium- to long-term follow-up are unclear. HYPOTHESIS: Patients will have favorable satisfaction at medium- to long-term follow-up and a high return to sport (RTS) rate after fasciotomy for treatment of CECS. STUDY DESIGN: Cross-sectional. LEVEL OF EVIDENCE: Level 3. METHODS: Retrospective review of patients who underwent fasciotomy for treatment of CECS from 2010 to 2021. Outcomes were assessed using Tegner Activity Scale, symptom resolution, patient satisfaction, return to activities, and EQ-5D-5L survey. RESULTS: Fifty patients (23 male and 27 female) were included. Mean age at time of surgery was 29.0 ± 11.6 years with mean follow-up 6.0 ± 2.3 years (range, 2.6-10.9). Tegner activity scores at final follow-up were improved compared with symptom onset (mean, 5.2 vs 3.3; P < 0.01). Increased preoperative symptom duration correlated with decreased RTS (ß = -0.447; P = 0.01) and return to work (RTW) (ß = -0.572; P = 0.01). Patients with a previous psychiatric diagnosis (n = 15) had lower rates of RTS (ß = -0.358; P = 0.03) and RTW (ß = -0.471, P = 0.02). Mean time to RTS was 5.5 ± 6.1 months. Mean visual analogue scale satisfaction rate was 74.4; 36 (72.0%) patients would be willing to have their fasciotomy again. Patients with fasciotomy of 1 to 2 compartments had higher Tegner score at final follow-up (P = 0.02) than those who had fasciotomy of >3 compartments; 19 (38.0%) patients reported experiencing paresthesia after their operation. No patients experienced major complications. CONCLUSION: Medium- to long-term outcomes of patients with CECS treated with fasciotomy demonstrated high satisfaction levels and high RTS rate. However, rate of minor complications including paresthesia, swelling, and cramping was high.

Long-term outcomes of primary ventral hernia repair associated with rectus diastasis.

Primary ventral hernia repair is a common global surgical procedure, entailing economic burdens and recurrence challenges. Rectus diastasis (RD) is considered a risk factor for midline defects and treatment is symptom-based. When primary ventral hernia and RD coexist, management still remains unclear. This study aims to analyze recurrence rates in patients after umbilical/epigastric hernia repair with untreated diastasis. Observational and retrospective cohort study of 74 patients assessing the recurrence rate of umbilical or epigastric hernias in patients operated with or without RD. Data were obtained from a tertiary hospital's patients between 2015 and 2017. Medium-term recurrences were analyzed after at least 3 year follow up. We compared demographic data, presence of RD (defined as rectus muscles separation exceeding 2 cm), type of repair and surgical complications. Data on 74 patients were collected. The mean age was 57.08 years, and the mean BMI was 31.27 kg/m2. Thirty-one included patients were females (42.9%). RD was documented in 67.1% of the sample. Mean follow-up was 4.23 (± 2.53) years. Postoperative complications were predominantly grade 1 according to the Clavien-Dindo classification, with a 17.14% surgical site infection rate. Female gender (p = 0.039), diabetes (0.016), and RD (0.049) showed statistically significant differences in predicting the risk of medium-term recurrence. Patients with untreated RD face a higher risk of medium-term recurrence following primary ventral hernia repair. Additionally, female gender and diabetes were found to be independent risk factors. Prospective studies are recommended to further assist surgeons in choosing the optimal surgical strategy for patients with umbilical hernia and associated RD.

State of the art treatment with Impella® in cardiac surgery in Austria.

Since 2022, the mechanical left ventricular support system Impella 5.5® has been used in Austria for patients with cardiogenic shock, advanced heart failure, post-cardiotomy and low output syndrome. The surgical insertion of the Impella 5.5 via the subclavian artery or alternatively via the ascending aorta has become an established procedure for medium-term treatment in patients with cardiogenic shock and bridging scenarios, such as bridge to recovery, bridge to left ventricular assist device (LVAD), bridge to decision, and bridge to heart transplant (HTx) in Austria. All Impella left ventricular heart pumps share the common feature of unloading the left ventricle, with the Impella 5.5 achieving a full cardiac output of 5.5 l/min. The stable positioning via transaxillary or transaortic insertion enables rapid extubation and mobilization of patients in the intensive care unit (ICU), leading to a significantly shorter ICU stay. The combined support of Impella 5.5 with venoarterial extracorporeal membrane oxygenation (VA-ECMO) has also proven effective in certain scenarios. Several nonrandomized studies demonstrated the effectiveness and safety of the Impella 5.5 in practice, which have been included in multiple international guidelines. The advantages of the Impella 5.5 in practice include the easy handling with high positional stability, and low complications rates. This article describes the significance of surgical Impella treatment in Austria from the perspective of Austrian clinical experts.

Clinical Outcomes of a Novel Hybrid Transtibial Technique for Femoral Tunnel Drilling in Anterior Cruciate Ligament Reconstruction: A Large Single-Center Case Series With a Minimum 2-Year Follow-up.

Background: A novel hybrid transtibial (HTT) approach to femoral tunnel drilling in anterior cruciate ligament reconstruction (ACLR) has been developed that circumvents the need for knee hyperflexion and orients the graft in the most anatomic position without sacrificing the tunnel length or aperture. Hypothesis: Patients who underwent ACLR utilizing the HTT technique would achieve excellent patient-reported outcome scores and experience low rates of graft failure and reoperations. Study Design: Case series; Level of evidence, 4. Methods: Patients who underwent primary ACLR at a single institution between 2005 and 2020 were retrospectively reviewed. Patients treated with the HTT, anteromedial portal (AMP), and transtibial (TT) approaches were matched based on age, sex, and body mass index ±3 kg/m2. Demographic and surgical data as well as femoral tunnel angle measurements on anteroposterior and lateral radiographs were collected for the 3 groups. However, clinical outcomes were only reported for the HTT group because of concerns of graft heterogeneity. Results: A total of 170 patients (median age, 26.5 years [interquartile range (IQR), 18.0-35.0 years]) who underwent ACLR using the HTT approach were included. The median coronal- and sagittal-plane femoral tunnel angles were 47° (IQR, 42°-53°) and 40° (IQR, 34°-46°), respectively. The sagittal-plane femoral tunnel angles in the HTT group were significantly more horizontal compared with those in the TT group (P < .0001), whereas the coronal-plane femoral tunnel angles in the HTT group were found to be significantly more vertical compared with those in the AMP group (P = .001) and more horizontal compared with those in the TT group (P < .0001). The graft failure and reoperation rates in the HTT group at a minimum 2-year follow-up were 1.8% (3/170) and 4.7% (8/170), respectively. The complication rate was 6.5% (11/170), with the most common complication being subjective stiffness in 7 patients. The median Lysholm score was 89.5 (IQR, 79.0-98.0); the median International Knee Documentation Committee score was 83.9 (IQR, 65.5-90.8); and the median Veterans RAND 12-Item Health Survey physical and mental component summary scores were 55.0 (IQR, 52.6-55.9) and 56.2 (IQR, 49.1-59.3), respectively. Conclusion: ACLR using the HTT technique was associated with low graft retear and revision surgery rates and good patient-reported outcome scores at medium-term follow-up and demonstrated femoral tunnel obliquity on postoperative radiographs that correlated with optimal parameters previously reported in cadaveric and biomechanical studies.

Assessing the medium-term effects of a community-based medical education program with homestay practice: a cohort study in Tamba, Japan.

INTRODUCTION: This study intended to evaluate the medium-term effectiveness of a community-based medical education (CBME) program and to determine the program's influence on the application rates of regional-quota students seeking to become residents in Tamba, Japan. MATERIALS AND METHODS: We conducted a cohort study of regional-quota students. Exposure factors included (1) experience compared to no experience of CBME in the Tamba area; (2) CBME experience compared to no experience in Tamba in the senior years (4-6 years of medical school) and experience in the junior years (1-3 years of medical school); and (3) experience in the senior years compared with those in the junior years. Outcome measures were applications to become a medical resident and actually becoming a medical resident at the Hyogo Prefectural Tamba Medical Center. RESULTS: Of 94 participants, 58 (61.7%) were male and 37 students (39.4%) had previous CBME experience in the Tamba area. In applying to become a resident at the Hyogo Prefectural Tamba Medical Center, students who had experienced CBME in the Tamba area in their senior years had significantly higher adjusted risk ratios compared to those who experienced it in their junior years. Regarding applications to become a resident, students who had experienced CBME in the Tamba area in their senior years had a significantly higher adjusted risk ratio than students who had not experienced CBME and students who had experienced CBME in their junior years. CONCLUSIONS: There was a statistically significant application rate for residency programs among medical students who participated in the CBME program in their senior years compared with those who did not. This is the first study to confirm the medium-term effects of CBME after several years in short-term CBME programs of three days and two nights.

Medical students who participated in our community-based medical education (CBME) program in their senior year were statistically and significantly more likely to apply for residency programs than those who did not.A short-term CBME program of three days and two nights incorporating a homestay practicum showed a medium-term effect after several years.Close contact with local residents is likely to influence future work location selection.

Combining models to generate consensus medium-term projections of hospital admissions, occupancy and deaths relating to COVID-19 in England.

Mathematical modelling has played an important role in offering informed advice during the COVID-19 pandemic. In England, a cross government and academia collaboration generated medium-term projections (MTPs) of possible epidemic trajectories over the future 4-6 weeks from a collection of epidemiological models. In this article, we outline this collaborative modelling approach and evaluate the accuracy of the combined and individual model projections against the data over the period November 2021-December 2022 when various Omicron subvariants were spreading across England. Using a number of statistical methods, we quantify the predictive performance of the model projections for both the combined and individual MTPs, by evaluating the point and probabilistic accuracy. Our results illustrate that the combined MTPs, produced from an ensemble of heterogeneous epidemiological models, were a closer fit to the data than the individual models during the periods of epidemic growth or decline, with the 90% confidence intervals widest around the epidemic peaks. We also show that the combined MTPs increase the robustness and reduce the biases associated with a single model projection. Learning from our experience of ensemble modelling during the COVID-19 epidemic, our findings highlight the importance of developing cross-institutional multi-model infectious disease hubs for future outbreak control.

Prognostic factors for recurrent instability in recreational athletes following arthroscopic Bankart repair: a retrospective study with an average 4.1-year follow-up.

BACKGROUND: Extensive research has been conducted to investigate the short-term and long-term outcomes of arthroscopic Bankart repair, yielding varying results across different populations. However, there remains a dearth of studies specifically focused on evaluating outcomes in recreational athletes. METHODS: A retrospective case series study was conducted on recreational athletes who underwent isolated arthroscopic Bankart repair between 2013 and 2021. The primary outcome assessed was recurrent instability, defined as dislocation or subluxation. Secondary outcomes included patient satisfaction, rates of returning to the same sports (RTS) and RTS at preinjury level, and patient-reported outcomes. Evaluation of the Rowe score, Constant score, American Shoulder and Elbow Surgeons score, and VAS pain score were performed. Prognostic factors for recurrent instability, including demographic and clinical characteristics, as well as postoperative magnetic resonance imaging (MRI) appearance of the labrum were analyzed. RESULTS: A total of 191 patients met the selection criteria, with 150 (78.5%) available for the final follow-up. Recurrent instability occurred in 10.7% of patients, with a mean follow-up duration of 4.1 years. Younger age at surgery and more critical glenoid bone loss were significantly associated with recurrent instability (p = .038 and p = .011, respectively). The satisfaction rate regarding surgery was 90.0%. Rates of return to the same sports (RTS) and RTS at preinjury level were 82.0% and 49.3%, respectively. Clinical outcomes measured at the final follow-up were as follows: Rowe score - 92.8; Constant score - 98.0; ASES score - 98.3; VAS pain score - 0.2. Patients with recurrent instability had significantly inferior outcomes in terms of satisfaction rate, RTS at preinjury level rate, Rowe score, and Constant score (p = .000, p = .039, p = .000, and p = .015, respectively). A total of thirty-seven patients underwent MRI examination six months after surgery in our institution. The T2-weighted anterior labrum morphology was found to be poorer in patients with recurrent instability. No significant difference was observed between patients with or without recurrent instability in terms of anterior Slope, anterior labral glenoid height index (LGHI), inferior Slope, inferior LGHI, and T2-weighted inferior labrum morphology. CONCLUSION: Arthroscopic Bankart repair can yield satisfactory medium-term outcomes for recreational athletes. Younger age at surgery, more critical glenoid bone loss, and poorer T2-weighted anterior labrum morphology assessed six months postoperatively were significantly associated with recurrent instability.

Arthroscopic Bankart Repair With Remplissage in Anterior Shoulder Instability Results in Fewer Redislocations Than Bankart Repair Alone at Medium-term Follow-up of a Randomized Controlled Trial.

BACKGROUND: A multicenter, double-blinded randomized controlled trial comparing isolated Bankart repair (NO REMP) to Bankart repair with remplissage (REMP) reported benefits of remplissage in reducing recurrent instability at 2 years postoperative. The ongoing benefits beyond this time point are yet to be explored. PURPOSE: To (1) compare medium-term (3 to 9 years) outcomes of these previously randomized patients undergoing isolated Bankart repair (NO REMP) or Bankart repair with remplissage (REMP) to manage recurrent anterior glenohumeral instability; (2) examine the failure rate, overall recurrent instability, and reoperation rate. STUDY DESIGN: Randomized controlled trial; Level of evidence, 1. METHODS: Recruitment and randomization for the original randomized trial occurred between 2011 and 2017. Patients ≥14 years diagnosed with recurrent traumatic anterior shoulder instability with an engaging Hill-Sachs defect of any size were included. Those with a glenoid defect >15% were excluded. In 2020, participants were contacted by telephone and asked standardized questions regarding ensuing instances of subluxation, dislocation, or reoperation on their study shoulder. "Failure" was defined as a redislocation, and "overall recurrent instability" was described as a redislocation or ≥2 subluxations. Descriptive statistics, relative risk, and Kaplan-Meier survival curve analyses were performed. RESULTS: A total of 108 participants were randomized, of whom 50 in the NO REMP group and 52 in the REMP group were included in the analyses in the original study. The mean number of months from surgery to the final follow-up was 49.3 and 53.8 months for the NO REMP and REMP groups, respectively. Failure rates were 22% (11/50) in the NO REMP group versus 8% (4/52) in the REMP group. Rates of overall recurrent instability were 30% (15/50) in the NO REMP group versus 10% (5/52) in the REMP group. Survival curves were significantly different, favoring REMP in both scenarios. CONCLUSION: For the treatment of traumatic recurrent anterior shoulder instability with a Hill-Sachs lesion and subcritical glenoid bone loss (<15%), a significantly lower rate of overall postoperative recurrent instability was observed with arthroscopic Bankart repair and remplissage than with isolated Bankart repair at a medium-term follow-up (mean of 4 years). Patients who did not receive a remplissage experienced a failure (redislocated) earlier and had a higher rate of revision/reoperation than those who received a concomitant remplissage.

Assessing and Improving the Care of Patients With Heart Failure in Ghana: Protocol for a Prospective Observational Study and the Ghana Heart Initiative-Heart Failure Registry.

BACKGROUND: Heart failure (HF) is a leading cause of morbidity and mortality globally, with a high disease burden. The prevalence of HF in Ghana is increasing rapidly, but epidemiological profiles, treatment patterns, and survival data are scarce. The national capacity to diagnose and manage HF appropriately is also limited. To address the growing epidemic of HF, it is crucial to recognize the epidemiological characteristics and medium-term outcomes of HF in Ghana and improve the capability to identify and manage HF promptly and effectively at all levels of care. OBJECTIVE: This study aims to determine the epidemiological characteristics and medium-term HF outcomes in Ghana. METHODS: We conducted a prospective, multicenter, multilevel cross-sectional observational study of patients with HF from January to December 2023. Approximately 5000 patients presenting with HF to 9 hospitals, including teaching, regional, and municipal hospitals, will be recruited and evaluated according to a standardized protocol, including the use of an echocardiogram and an N-terminal pro-brain natriuretic peptide (NT-proBNP) test. Guideline-directed medical treatment of HF will be initiated for 6 months, and the medium-term outcomes of interventions, including rehospitalization and mortality, will be assessed. Patient data will be collated into a HF registry for continuous assessment and monitoring. RESULTS: This intervention will generate the necessary information on the etiology of HF, clinical presentations, the diagnostic yield of various tools, and management outcomes. In addition, it will build the necessary capacity and support for HF management in Ghana. As of July 30, 2023, the training and onboarding of all 9 centers had been completed. Preliminary analyses will be conducted by the end of the second quarter of 2024, and results are expected to be publicly available by the middle of 2024. CONCLUSIONS: This study will provide the necessary data on HF, which will inform decisions on the prevention and management of HF and form the basis for future research.

Medium-term exposure to size-fractioned particulate matter and asthma exacerbations in China: A longitudinal study of asthmatics with poor medication adherence.

BACKGROUND: Studies have shown that short- and long-term exposure to particulate matter (PM) can increase the risk of asthma morbidity and mortality. However, the effect of medium-term exposure remains unknown. We aim to examine the effect of medium-term exposure to size-fractioned PM on asthma exacerbations among asthmatics with poor medication adherence. METHODS: We conducted a longitudinal study in China based on the National Mobile Asthma Management System Project that specifically and routinely followed asthma exacerbations in asthmatics with poor medication adherence from April 2017 to May 2019. High-resolution satellite remote-sensing data were used to estimate each participant's medium-term exposure (on average 90 days) to size-fractioned PM (PM1, PM2.5, and PM10) based on the residential address and the date of the follow-up when asthma exacerbations (e.g., hospitalizations and emergency room visits) occurred or the end of the follow-up. The Cox proportional hazards model was employed to examine the hazard ratio of asthma exacerbations associated with each PM after controlling for sex, age, BMI, education level, geographic region, and temperature. RESULTS: Modelling results revealed nonlinear exposure-response associations of asthma exacerbations with medium-term exposure to PM1, PM2.5, and PM10. Specifically, for emergency room visits, we found an increased hazard ratio for PM1 above 22.8 µg/m3 (1.060, 95 % CI: 1.025-1.096, per 1 µg/m3 increase), PM2.5 above 38.2 µg/m3 (1.032, 95 % CI: 1.010-1.054), and PM10 above 78.6 µg/m3 (1.019, 95 % CI: 1.006-1.032). For hospitalizations, we also found an increased hazard ratio for PM1 above 20.3 µg/m3 (1.055, 95 % CI: 1.001-1.111) and PM2.5 above 39.2 µg/m3 (1.038, 95 % CI: 1.003-1.074). Furthermore, the effects of PM were greater for a longer exposure window (90-180 days) and among participants with a high BMI. CONCLUSION: This study suggests that medium-term exposure to PM is associated with an increased risk of asthma exacerbations in asthmatics with poor medication adherence, with a higher risk from smaller PM.

Autologous microfragmented adipose tissue treatment of knee osteoarthritis demonstrates effectiveness in 68% of patients at 4-year follow-up.

BACKGROUND: Adipose tissue-derived stem cells are an interesting therapeutic option for early knee osteoarthritis (OA) treatment due to their high plasticity, easiness of harvesting and rapidity of administration. The aim of this study was to evaluate the medium-term effectiveness and safety of Microfragmented Autologous Fat Tissue (MFAT) injection treatment at 4-year follow-up and to investigate potential correlations among patients' pre-treatment clinical condition and clinical outcomes to identify possible predicting factors for procedure success or failure. PATIENTS AND METHODS: This is a prospective trial enrolling 46 patients with diagnosis of symptomatic knee OA and failure of previous conservative measures who underwent diagnostic arthroscopy and single autologous MFAT injection between June 2017 and July 2018. Patients were assessed with repeated clinical scoring systems at baseline, 6 months, 1 and 4 years after surgery. The evaluation included demographic characteristics, arthroscopic findings, and stem cell number from injected tissue. RESULTS: No major complications were reported during follow-up period and there was a significant increase of Lysholm knee score from baseline value of 61.7 ± 13.8 to 79.5 ± 16.9 at 4 years (p < 0.001). The WOMAC score increased from a baseline value of 66.5 ± 14.7 to 82.8 ± 15.7 at 4 years (p < 0.001) and there was a significant decrease of VAS pain score from baseline value of 6.3 ± 1.5 to 3.5 ± 2.6 at 4-year follow-up (p < 0.001). ROM improved significantly from 118.4 ± 2.6 to 122.5 ± 2.5 at 12 months (p < 0.001), but did not improve at 4 years (p > 0.05). 15 patients (32.6%) were considered treatment failures, because they required secondary surgery, further injection therapy or experienced symptoms persistence. Patient with synovitis had 75% failure rate, although synovitis did not result as a statistically significant factor influencing clinical outcome up to 4-year follow-up (p = 0.058). Age, cartilage defects severity, BMI, concomitant procedures, and stem cell number from injected MFAT did not show any significant correlation with the results. CONCLUSIONS: MFAT intra-articular injection is a safe procedure with positive improvements up to 4-year follow-up in patients with early knee OA. These findings suggest MFAT could be a minimally invasive treatment of early knee OA with durable benefits at mid-term evaluation. TRIAL REGISTRATION: IRB number ID-3522.

Short and Medium Term Outcomes of Open and Laparoscopic Assisted Oesophageal Replacement Procedures.

AIM OF THE STUDY: We describe the short- and medium-term outcomes following open and laparoscopic assisted oesophageal replacement surgery in a single tertiary paediatric surgical centre. METHODS: A retrospective review (institutional audit approval no. 3213) on patients who underwent open or laparoscopic-assisted oesophageal replacement (OAR vs. LAR) at our centre between 2002 and 2021 was completed. Data collected (demographics, early complications, stricture formation, need for oesophageal dilatations, and mortality) were analysed using GraphPad Prism v 9.50 and are presented as median (IQR). RESULTS: 71 children (37 male) had oesophageal replacement surgery at a median age of 2.3 years (IQR 4.7 years). 51 were LAR (6 conversions). Replacement conduit was stomach (n = 67), colon (n = 3), or jejunum (n = 1). Most gastric transpositions had a pyloroplasty (46/67) or pyloromyotomy (14/67). Most common pathology was oesophageal atresia (n = 50 including 2 failed transpositions), caustic injury (n = 19 including 3 due to button battery), stricture of unknown cause (n = 1), and megaoesophagus (n = 1). There were 2 (2.8 %) early postoperative deaths at 2 days (major vessel thrombosis), 1 month (systemic sepsis), and one death at 5 years in the community. The rate of postoperative complications were comparable across LAR and OAR including anastomotic leak, pleural effusions, or early strictures. More patients with caustic pathology needed dilatations (60 % vs 30 % in OA, p = 0.05). CONCLUSIONS: Outcomes of open and laparoscopic-assisted oesophageal replacement procedures are comparable in the short and medium term. Anastomotic stricture is higher in those with caustic injury. LEVEL OF EVIDENCE: IV.

Medium-to-long term sustainability of a health systems intervention to improve service readiness and quality of non-communicable disease (NCD) patient care and experience at primary care settings in Uganda.

BACKGROUND: With the double burden of rising chronic non-communicable diseases (NCDs) and persistent infectious diseases facing sub-Saharan Africa, integrated health service delivery strategies among resource-poor countries are needed. Our study explored the post-trial sustainability of a health system intervention to improve NCD care, introduced during a cluster randomised trial between 2013 and 2016 in Uganda, focusing on hypertension (HT) and type-2 diabetes mellitus (DM) services. In 2020, 19 of 38 primary care health facilities (HFs) that constituted the trial's original intervention arm until 2016 and 3 of 6 referral HFs that also received the intervention then, were evaluated on i) their facility performance (FPS) through health worker knowledge, and service availability and readiness (SAR), and ii) the quality-of-patient-care-and-experience (QoCE) received. METHODS: Cross-sectional data from the original trial (2016) and our study (2020) were compared. FPS included a clinical knowledge test with 222 health workers: 131 (2016) and 91 (2020) and a five-element SAR assessment of all 22 HFs. QoCE assessment was performed among 420 patients: 88 (2016) and 332 (2020). Using a pair-matched approach, FPS and QoCE summary scores were compared. Linear and random effects Tobit regression models were also analysed. RESULTS: The mean aggregate facility performance (FPS) in 2020 was lower than in 2016: 70.2 (95%CI = 66.0-74.5) vs. 74.8 (95%CI = 71.3-78.3) respectively, with no significant difference (p = 0.18). Mean scores declined in 4 of 5 SAR elements. Overall FPS was negatively affected by rural or urban HF location relative to peri-urban HFs (p < 0.01). FPS was not independently predicted but patient club functionality showed weak association (p = 0.09). QoCE declined slightly to 8.7 (95%CI = 8.4-91) in 2020 vs 9.5 (95%CI = 9.1-9.9) in 2016 (p = 0.02) while the proportion of patients receiving adequate quality care also declined slightly to 88.2% from 98.5% respectively, with no statistical difference (p = 0.20). Only the parent district weakly predicted QoCE (p = 0.05). CONCLUSIONS: Four years after the end of research-related support, overall facility performance had declined as expected because of the interrupted supplies and a decline in regular supervision. However, both service availability and readiness and quality of HT/DM care were surprisingly well preserved. Sustainability of an NCD intervention in similar settings may remain achievable despite the funding instability following a trial's end but organisational measures to prepare for the post-trial phase should be taken early on in the intervention process.

Sustainability capacity and health worker normalisation of a successful non-communicable disease (NCD) health systems intervention within primary care settings in Uganda: a quantitative approach to a qualitative question.

BACKGROUND: Interventions for non-communicable diseases are increasingly implemented and evaluated in sub-Saharan Africa, but little is known about their medium- to long-term sustainability beyond the end of research funding. A cluster randomised trial conducted between 2013 and 2016 in Uganda and Tanzania showed that an intervention package to improve hypertension (HT) and type-2 diabetes mellitus (DM) care was highly effective in increasing service readiness and quality of care. The present study assesses the sustainability of the intervention 4 years after the trial in Uganda. METHODS: The study was conducted in 2020 in 22 primary care health facilities (HFs) (3 referrals and 19 lower-level units) that had received the intervention package until trial end (2016), to assess their current capacity and practice to sustain ongoing intervention activities for HT and DM care. Through a cross-sectional survey, 4 pre-defined domains (i.e., cognitive participation, coherence, collective action, and reflexive monitoring) were examined with regard to health worker (HW) normalization and 8 pre-defined domains for intervention sustainability (i.e., organisational capacity, local environment, funding stability, partnerships, communication, evaluation, adaptation, and strategic planning), using the normalisation tool and the program sustainability tool (PSAT). Summary scores were assessed by domains and facility level. RESULTS: Overall normalization strength was adequate at 4.0 (IQR: 3.8, 4.2) of a possible 5 with no evidence of association with HF level (p = 0.40); cognitive participation (buy-in) and reflexive monitoring (appraisal) were strongest at > 4 across all HF levels. All HF levels were weak (< 4) on collective action (teamwork) and coherence (sense-making). Only collective action differed by level (p < 0.002). Overall intervention sustainability was suboptimal at 3.1 [IQR: 1.9, 4.1] of a possible 7 with weak scores on funding stability (2.0), supportive partnerships (2.2), and strategic planning (2.6). Domain differences by HF level were significant for environmental support (p = 0.02) and capacity in organisation (p = 0.01). Adequate strength at a cut-off mean of ≥5 did not differ by HF level for any domain. CONCLUSIONS: Four years after their introduction, practice-dependent intervention elements e.g., local organisational context, HW knowledge or dedication were sustained, but external elements e.g., new funding support or attracting new partners to sustain intervention efforts were not. Whenever new interventions are introduced into an existing health service, their long-term sustainability including the required financial support should be ensured. The quality of services should be upheld by providing routine in-service training with dedicated support supervision.

Development, Management and Utilization of a Kiwifruit (Actinidia spp.) In Vitro Collection: A New Zealand Perspective.

The New Zealand Institute for Plant and Food Research Limited (PFR) supports a large kiwifruit breeding program that includes more than twenty Actinidia species. Almost all the kiwifruit accessions are held as field collections across a range of locations, though not all plants are at multiple locations. An in vitro collection of kiwifruit in New Zealand was established upon the arrival of Pseudomonas syringae pv. Actinadiae-biovar 3 in 2010. The value of an in vitro collection has been emphasized by restrictions on importation of new plants into New Zealand and increasing awareness of the array of biotic and abiotic threats to field collections. The PFR in vitro collection currently holds about 450 genotypes from various species, mostly A. chinensis var. chinensis and A. chinensis var. deliciosa. These collections and the in vitro facilities are used for germplasm conservation, identification of disease-free plants, reference collections and making plants available to users. Management of such a diverse collection requires appropriate protocols, excellent documentation, training, sample tracking and databasing and true-to-type testing, as well as specialized facilities and resources. This review also discusses the New Zealand biosecurity and compliance regime governing kiwifruit plant movement, and how protocols employed by the facility aid the movement of pathogen-free plants within and from New Zealand.

Effects of Short- And Medium-Term Exposures to Lower Air Temperature on 71 Novel Biomarkers of Subclinical Inflammation: Results from the KORA F4 Study.

Increasing evidence has revealed that exposure to low temperatures is linked to a higher risk of chronic diseases and death; however, the mechanisms underlying the observed associations are still poorly understood. We performed a cross-sectional analysis with 1115 participants from the population-based KORA F4 study, which was conducted in Augsburg, Germany, from 2006 to 2008. Seventy-one inflammation-related protein biomarkers were analyzed in serum using proximity extension assay technology. We employed generalized additive models to explore short- and medium-term effects of air temperature on biomarkers of subclinical inflammation at cumulative lags of 0-1 days, 2-6 days, 0-13 days, 0-27 days, and 0-55 days. We found that short- and medium-term exposures to lower air temperature were associated with higher levels in 64 biomarkers of subclinical inflammation, such as Protein S100-A12 (EN-RAGE), Interleukin-6 (IL-6), Interleukin-10 (IL-10), C-C motif chemokine 28 (CCL28), and Neurotrophin-3 (NT-3). More pronounced associations between lower air temperature and higher biomarker of subclinical inflammation were observed among older participants, people with cardiovascular disease or prediabetes/diabetes, and people exposed to higher levels of air pollution (PM2.5, NO2, and O3). Our findings provide intriguing insight into how low air temperature may cause adverse health effects by activating inflammatory pathways.

Grassroots stakeholders' perception of participation in the Medium-Term Development Plan of District Assemblies in Ghana: The case of Sawla-Tuna-Kalba District.

Following Ghana's decentralisation policy, the District Assemblies, in consultation with communities, are required to prepare and implement Medium-Term Development Plans [MTDPs] to ensure the overall development of their respective jurisdictions. However, little consideration has been given to the participation of grassroots stakeholders in the development of MTDPs. Consequently, this study investigates the participation of grassroots stakeholders in developing MTDPs. A cross-sectional survey involving 139 respondents was deployed. The data were gathered using a questionnaire and an interview guide, and it was analyzed using descriptive statistics, Spearman's Rank Correlation, and thematic analysis. Results indicated that grassroots stakeholders were aware of their right to participate in the preparation of MTDPs. As such, they actively participated in the process that led to developing such plans addressing community needs. Additionally, awareness of MTDP, involvement, level of influence, satisfaction with the preparation of MTDPs, satisfaction with the quality of participation in the area council, level of confidence in the preparation of MTDP, representation adequacy, and capture of community needs had statistically significant associations at the 1% level with the associations being positive. Nonetheless, the implementation of MTDPs is jeopardised by limited funding, stakeholder commitment, and human capacity. To ensure the smooth implementation of the MTDPs, the Assembly must intensify its revenue mobilisation efforts, depoliticise the MTDP process, and build staff capacity on the involvement of the grassroots stakeholders.

Medium-term scenarios of COVID-19 as a function of immune uncertainties and chronic disease.

As the SARS-CoV-2 trajectory continues, the longer-term immuno-epidemiology of COVID-19, the dynamics of Long COVID, and the impact of escape variants are important outstanding questions. We examine these remaining uncertainties with a simple modelling framework that accounts for multiple (antigenic) exposures via infection or vaccination. If immunity (to infection or Long COVID) accumulates rapidly with the valency of exposure, we find that infection levels and the burden of Long COVID are markedly reduced in the medium term. More pessimistic assumptions on host adaptive immune responses illustrate that the longer-term burden of COVID-19 may be elevated for years to come. However, we also find that these outcomes could be mitigated by the eventual introduction of a vaccine eliciting robust (i.e. durable, transmission-blocking and/or 'evolution-proof') immunity. Overall, our work stresses the wide range of future scenarios that still remain, the importance of collecting real-world epidemiological data to identify likely outcomes, and the crucial need for the development of a highly effective transmission-blocking, durable and broadly protective vaccine.

Short- and medium-term outcomes of video-assisted thoracoscopic surgery versus thoracotomy for carinal lung resection combined with carina reconstruction in locally advanced non-small cell lung cancer patients.

BACKGROUND: The application of video-assisted thoracoscopic surgery (VATS) for complex carina surgeries in treating non-small cell lung cancer (NSCLC) patients with involved carina is controversial. This study compared short- and medium-term outcomes of VATS versus thoracotomy for carinal lung resection with carina reconstruction in treating locally advanced NSCLC, aiming to assess the potential benefit of VATS over thoracotomy for these patients. METHODS: A total of 37 consecutive NSCLC cases receiving VATS (n = 14) or thoracotomy (n = 23) for carinal lung resection with carina reconstruction from 2016 to 2021 were retrospectively identified. Baseline clinicopathological characteristics, perioperative outcomes, and survival profiles were investigated. RESULTS: Patients in the VATS and thoracotomy groups had comparable baseline clinicopathological characteristics (all p > 0.050). VATS decreased postoperative drainage volume compared with thoracotomy (1280 [1170-1510] vs. 1795 [1510-1905] mL, p = 0.012). Regarding surgical-related pains, VATS reduced numeric rating scale scores on the postoperative day 1 (4 [3, 4] vs. 5 [4, 5], p = 0.021) and day 2 (3 [3, 4] vs. 5 [3-5], p = 0.023) than thoracotomy. No difference was found between the VATS and thoracotomy groups in other perioperative outcomes, postoperative complications, and assessment of lymph nodes (LNs) and LN stations (all p > 0.050). Moreover, patients in the two groups had comparable 3-year disease-free survival (DFS), overall survival (OS), and recurrence and mortality patterns. Further subgroup and Cox hazards regression analyses also observed no difference in DFS or OS between the two groups. CONCLUSIONS: VATS reduced postoperative drainage volume and ameliorated surgical-related pain, and achieved comparable medium-term survival compared to thoracotomy for carinal lung resection with carina reconstruction in treating locally advanced NSCLC.
