ABSTRACT

BACKGROUND: Concurrent opioid and stimulant use is on the rise in North America. This increasing trend of use has been observed in the general population, and among people released from prison in British Columbia (BC), who face an elevated risk of overdose post-release. Opioid agonist treatment is an effective treatment for opioid use disorder and reduces risk of overdose mortality. In the context of rising concurrent stimulant use among people with opioid use disorder, this study aims to investigate the impact of stimulant use disorder on opioid agonist treatment dispensation following release from prison in BC.

METHODS: Linked health and corrections records were retrieved for releases between January 1^st 2015 and December 29^th 2018 (N = 13,380). Hospital and primary-care administrative health records were used to identify opioid and stimulant use disorder and mental illness. Age, sex, and health region were derived from BC’s Client Roster. Incarceration data were retrieved from provincial prison records. Opioid agonist treatment data was retrieved from BC’s provincial drug dispensation database. A generalized estimating equation produced estimates for the relationship of stimulant use disorder and opioid agonist treatment dispensation within two days post-release.

RESULTS: Cases of release among people with an opioid use disorder were identified (N = 13,380). Approximately 25% (N = 3,328) of releases ended in opioid agonist treatment dispensation within two days post-release. A statistically significant interaction of stimulant use disorder and mental illness was identified. Stratified odds ratios (ORs) found that in the presence of mental illness, stimulant use disorder was associated with lower odds of obtaining OAT [(OR) = 0.73, 95% confidence interval (CI) = 0.64-0.84)] while in the absence of mental illness, this relationship did not hold [OR = 0.89, 95% CI = 0.70-1.13].

CONCLUSIONS: People with mental illness and stimulant use disorder diagnoses have a lower odds of being dispensed agonist treatment post-release compared to people with mental illness alone. There is a critical need to scale up and adapt opioid agonist treatment and ancillary harm reduction, and treatment services to reach people released from prison who have concurrent stimulant use disorder and mental illness diagnoses.

ABSTRACT

BACKGROUND: Central sensitization syndrome (CSS) involves severe functional symptoms due to central sensitization. for patients with severe somatic symptoms and related disorders (SSRDs), central sensitization may be responsible for their functional symptoms. We hypothesized that screening for CSS in patients with SSRDs would identify those with severe disease. The Somatic Symptom Scale-8 (SSS-8) is a simple tool to assess medical conditions related to SSRDs, but the cut-off point to identify severe cases of comorbid CSS is unknown. This study aimed to determine the optimal cut-off point of SSS-8 for screening the CSS of patients with severe SSRDs.

METHODS: In total, 143 patients with SSRDs attending outpatient clinics of a university hospital in Japan were included in the study. The participants were evaluated using the SSS-8 for somatic symptoms, Hospital Anxiety and Depression Scale (HADS) for anxiety and depressive symptoms, Pain Catastrophizing Scale (PCS) for catastrophic thoughts, and Central Sensitization Inventory (CSI-A, B) for CSS. Receiver operating characteristic (ROC) curve analysis was performed using the propensity score. The area under the curve (AUC) was calculated using a propensity score considering PCS, age, sex, HADS, and CSI-B as confounders of SSS-8 and CSS to evaluate differences in diagnostic accuracy between patients with and without SSS-8. The sensitivity and specificity of the ROC analysis were then used to determine the cut-off point for discriminating severe cases of SSS-8.

RESULTS: Of the 143 participants, 126 responded (51 CSS group and 75 non-CSS group), with a valid response rate of 88.1 percent. In the ROC analysis, the propensity score including SSS-8 was statistically more accurate. The optimal cut-off point was 13, with an AUC of 0.88, sensitivity of 84.3 percent, and specificity of 77.3 percent.

CONCLUSIONS: The SSS-8 is a useful tool for discriminating severe cases of SSRDs comorbid with CSS.

ABSTRACT

PURPOSE: Up to 20% of all patients are not satisfied with the result after total knee arthroplasty (TKA). To improve patient satisfaction manufacturers have modified prosthesis design. The ATTUNE prosthesis is a modified version of the PFC Sigma. Aim of this study was to evaluate the outcome at 6 months and 5 years after TKA with ATTUNE compared to PFC Sigma.

METHODS: Sixty patients were included prospectively (30 ATTUNE vs. 30 PFC Sigma). Knee Society Score and Hospital for Special Surgery Score were recorded preoperatively, at 6 months and at least 5 years postoperatively. At 5-years follow-up X-rays in two planes were evaluated, radiolucent lines were documented.

RESULTS: Patient characteristics were similar in both groups. Both ATTUNE and PFC Sigma provided good to excellent clinical results. There were no statistically significant differences based on the overall scores and patient rated outcome measures. Nevertheless, patients in the ATTUNE group tended to be symptom-free earlier and to achieve better clinical results after 5 years.

CONCLUSION: Even with the scores not being significantly different here, the modified design of ATTUNE could increase long-term satisfaction with the implant and reduce the need for revision surgery. However, long-term results are required to prove this.

ABSTRACT

BACKGROUND: Promoting health early in life is crucial to obesity prevention, but families in under-resourced communities face barriers to establishing healthy routines. The purpose of this pilot study was to examine the feasibility and preliminary effects of two dietary interventions for families in under-resourced communities.

METHODS: Fifty-one caregivers of young children (aged 0-5 years) were recruited from six community centers located in heavily populated neighborhoods with high poverty rates (i.e., under-resourced neighborhoods) in southwestern Pennsylvania. A longitudinal pilot study was conducted to examine feasibility as a primary outcome and change in dietary variety (24-Hour Recall), risk of nutritional problems (Nutrition Screen for Every Preschooler), and parenting stress (Parenting Stress Index-Short Form) over time and between groups as secondary outcomes. Six sites were randomized to receive Cooking Matters for Parents, Mealtime PREP, or a combined program (Cooking Matters + Mealtime PREP). Cooking Matters for Parents is a six-week nutrition education program designed to help parents of young children plan and cook healthy meals on a budget. Mealtime PREP is a six-week routine-based intervention designed to promote healthy dietary variety among young children. We predicted that we could feasibly deliver both programs and the combined program as determined by a priori benchmarks (ability to recruit ≥ 8 participants per site; achieving an 80% intervention completion rate; being rated as an acceptable intervention by 95% of intervention completers, and treatment fidelity of ≥ 90%). Descriptive statistics and individual growth models were used to analyze data.

RESULTS: Of 51 recruited participants, 49 were eligible, randomized by site, and included in the analyses. Fourteen were randomized to Cooking Matters, 13 to Mealtime PREP, and 22 to the combined program. Three of 4 feasibility benchmarks were met. Over time, improvements were observed in child dietary variety (p < 0.01, SE = 0.99), child nutrition risk (p = 0.01, SE = 0.61), and parenting stress (p = 0.04, SE = 1.33). An additive benefit of the combined intervention was observed for dietary variety (p = 0.03, SE = 0.79). No adverse events were observed or reported.

CONCLUSIONS: Offering complementary dietary interventions in under-resourced communities is feasible and shows promise to improve child and parent health.

ABSTRACT

BACKGROUND: Antimicrobial resistance (AMR) is an important global health concern, projected to contribute to significant mortality, particularly in developing countries. This study aimed to determine the knowledge, perceptions of clinical health professions students towards antimicrobial resistance and rational use of medicine and confidence level to prescribe antimicrobials.

METHODS: An online descriptive cross-sectional survey was conducted among clinical health professions students across 9 medical schools in Uganda. A semi-structured questionnaire using Kobo Toolbox form was shared among participants via WhatsApp Messenger (Meta, California, USA). Knowledge was categorized using modified Bloom’s cut-off. One-way ANOVA, Chi-square or Fisher’s exact test, and logistic regression were used to assess the association between dependent and independent variables. A p < 0.05 was considered statistically significant.

RESULTS: We surveyed 681 participants, most were pursuing a Bachelor of Medicine and Surgery degree (n = 433, 63.6%), with a mean age of 24 (standard deviation: 3.6) years. Most participants (n = 596, 87.5%) had sufficient knowledge about antimicrobial resistance with a mean score of 85 ± 14.2%. There was a significant difference in mean knowledge scores of year 4 (86.6%) compared to year 3 (82.4%) (p = 0.002) and year 5 (88.0%) compared to year 3 (82.4%) (p < 0.001). Most participants (n = 456, 66.9%), were confident on making an accurate diagnosis of infection, and choosing the correct antimicrobial agent to use (n = 484, 71.1%).

CONCLUSION: Health profession students exhibited good knowledge on antimicrobial resistance and high self-perceived confidence that should be leveraged to foster better future antimicrobial prescription practices. However, they still agreed that a separated course unit on AMR is necessary which responsible authorities should consider to consolidate the efforts.

ABSTRACT

BACKGROUND: Public safety personnel (PSP) are exposed to potentially psychologically traumatic events (PPTE) far more often than the general public, which increases the risk for various post-traumatic stress injuries (PTSIs). While there are many evidence-based psychological interventions for PTSI, the effectiveness of each intervention for PSP remains unclear.

OBJECTIVES: The current study assessed the effectiveness and acceptability of psychological interventions for PTSI among PSPs.

METHODS: A systematic review and random-effects meta-analysis were performed on the effectiveness and acceptability of psychotherapies for PTSIs (i.e., symptoms of depression, anxiety, post-traumatic stress disorder) among PSP. The review adhered to the PRISMA reporting guidelines and used standardized mean differences (Cohen’s d), rate ratios (RR), and their 95% confidence intervals (95% CI) to measure pooled effect sizes across studies; negative d values and RR values less than one indicated a reduction in symptoms compared to baseline or control groups. In addition, heterogeneity was quantified using I², and publication bias was evaluated using Egger’s test.

RESULTS: The analyses included data from eight randomized controlled trials representing 402 PSP (79.4% male, 35.3 years). Psychological interventions included narrative exposure therapy (n = 1), cognitive behavioral therapy (n = 2), eclectic psychotherapy (n = 2), eye-movement desensitization and reprocessing (n = 1), supportive counseling (n = 2), and group critical incident stress debriefing (n = 1). The interventions were associated with statistically significant reductions in symptoms associated with PTSD (d = – 1.23; 95% CI – 1.81, – 0.65; 7 studies; I² = 81%), anxiety (- 0.76; 95% CI – 1.28, – 0.24; 3 studies; I² = 47%), and depression (d = – 1.10; 95% CI – 1.62, – 0.58; 5 studies; I² = 64%). There were smaller but statistically significant improvements at follow-up for symptoms of PTSD (d = – 1.29 [- 2.31, – 0.27]), anxiety (d = – 0.82 [- 1.20, – 0.44]), and depression (d = – 0.46 [- 0.77, – 0.14]). There were no statistically significant differences in dropout rates (RR = 1.00 [0.96, 1.05]), suggesting high acceptability across interventions.

CONCLUSIONS: There is preliminary evidence that psychotherapies help treat PTSIs in PSP; however, the shortage of high-quality studies on PSP indicates a need for additional research into treating PTSI among PSP.

ABSTRACT

BACKGROUND: Patients diagnosed with cancer are at higher risk of anxiety, depression, and overall distress. These mood disturbances are risk factors for non-adherence to cancer treatment, increased length of stay during hospital admissions, increased number of visits to the emergency department, and also impact survival. Although paper handouts about the potential side effects are widely used in the oncology practice studies have shown that digital educational material is known to work better when compared to traditional methods. However, the impact of video education on anxiety, depression, and distress have not been previously evaluated. Our study aimed to assess whether video education about potential chemotherapy and immunotherapy can reduce anxiety, depression, and distress levels.

METHODS: After IRB approval, we enrolled patients who were fluent in English, younger than 80 years of age, and who were able to provide informed consent. The Hospital Anxiety and Depression Scale and Distress Thermometer were used to assess distress, as well as depression and anxiety before and after watching video educational material. Paired t-test was used to compare the differences between the scores before and after watching educational videos. The statistical software GraphPad Prism 9, San Diego, California, was used to perform the statistical analysis.

RESULTS: We enrolled 29 patients, of whom 20 completed the study, six withdrew, two were lost to follow-up, and one did not complete the initial questionnaire. Of all patients that completed the study 85% of the patient found videos helpful, and they were 7/10 likely to recommend them to other patients who may experience symptoms. The mean depression score changed from 4.75 before to 4.9 after watching the videos (p 0.77), distress score from 2.3 to 2.65 (p 0.52), and anxiety scores changed from 4.85 to 6.15 (p 0.03). The feedback provided by the patients indicated that they were more willing to watch the videos related to the side effects they experienced at their free time and convenience.

CONCLUSIONS: Our study suggests that patients were open to video education and found it helpful and worth watching. However, the exposure of the patients to the videos about potential side effects of cancer treatment, including those patients do not experience, may lead to increased anxiety.

ABSTRACT

BACKGROUND: Breast cancer is a heterogeneous disease that has various clinical outcomes. Bax-interacting factor-1 (Bif-1) is a member of the endophilin B family that generates the pro-apoptotic BCL2-Associated X (BAX) protein in response to apoptotic signals. Lack of Bif-1 inhibits the intrinsic pathway of apoptosis and enhancements the risk of tumor genesis. The present study aimed to investigate the relationship between hormone receptors (ER, PR, and HER2) status and different levels of Bif-1 gene expression in breast cancer patients.

METHODS: Bif-1 gene expression was evaluated in 50 breast cancer tumors and 50 normal breast mammary tissues using the SYBR Green real-time RT-PCR technique. Multivariate and univariate analyses were used to appraise the relationship between the prognostic significance of the Bif-1 gene using SPSS software. In this study, the Bif-1 was selected as a candidate for a molecular biomarker and its expression status in breast cancer patients with hormone receptors (ER, RR, and HER2) compared to patients without these hormone receptors.

RESULTS: The study showed that the relative expression of the Bif-1 gene in tissues of patients with hormone receptors in breast cancer compared to those without hormone receptors was not statistically significant. The expression levels of the Bif-1 gene in different groups were evaluated for hormone receptor status. No significant relationship was found between the Bif-1 gene expression and hormone receptors (ER, PR, and HER2) (p > 0.05).

CONCLUSION: Bif-1 gene expression may be a useful prognostic marker in breast cancer.

ABSTRACT

BACKGROUND: The women-friendly care approach focuses on women’s rights to have access to quality care for themselves as individuals, as mothers, and for their infants. However, access to quality health services is not guaranteed for many women, particularly in low and middle-income countries. Hence, this study aimed to assess the level of women-friendly care provision and associated factors among mothers in the immediate post-partum period at public hospitals of Bale Zone, Southeast Ethiopia 2021.

METHODS: An institutional-based cross-sectional survey was employed among mothers in the immediate post-partum period in public hospitals of Bale Zone from March 1-30, 2021. A total of 363 mothers were recruited by systematic random sampling technique in this study. Data was collected through pre-tested structured questionnaires. A 21-verified questionnaire was used to measure the outcome variable. The data were entered into Epi Data version 4.6.2.0 and exported to the statistical package of social science version 26.0 for analysis. A variable with a P value of less than 0.25 in the bi-variable binary logistic regression model was transferred to a multivariable binary logistics regression model. Hosmer and Lemeshow’s goodness of fit model was checked. Adjusted odds ratio with 95% confidence intervals were used to estimate the strength of association between the outcome variable and independent variables. A p-value less than 0.05 was considered as significantly associated.

RESULTS: The level of women-friendly care provision among mothers in immediate post-partum at public hospitals of Bale Zone was found to be 61% [95% confidence interval (55.73-66.04)]. Being prim para mother [Adjusted odds ratio = 1.88(1.07-3.33)], having planned pregnancy [Adjusted odds ratio = 1.94(1.04-3.63)] and staying at a health facility after delivery [Adjusted odds ratio = 4.8(1.71-13.39)] were found to be statistically significant predictors of level of women-friendly care provision.

CONCLUSION: The women-friendly care provision among mothers in the immediate post-partum period in this study area was found to be low against most of the pre-existing findings. Strong counseling on planned pregnancy and staying at a health facility after delivery is recommended.

ABSTRACT

BACKGROUND: Prospective study objectives. A sagittal balance is a good tool to improve the functional outcome of spine spondylolisthesis surgeries, primarily noted that it has a good impact in deformity surgery and then applied to every spine surgery and the aim of this study is to evaluate its functional outcome when considered in preoperative planning for non-dysplastic low- and mid-grade spondylolisthesis surgeries.

METHOD: Forty patients diagnosed as low- or mid-grade non-dysplastic spondylolisthesis had undergone surgery at Cairo University after failed medical treatment had been evaluated preoperatively by measuring the sagittal balance parameters which include SVA, spinopelvic angles, lumbar lordosis, pelvic tilt, sacral slope, and pelvic incidence and then measure it along a follow-up period of 1 year postoperatively started from February 2018 and correlate it with functional outcome using Oswestry score (ODI)and VAS. Correction of parameters has been estimated preoperatively by manual estimation and Surgimap application then applied during the operation.

RESULTS: All patients were treated by surgical treatment through posterior transpedicular screw fixation with conventional or reduction screws and fusion ± TLIF cages. The mean of lumbar lordosis and mean spinopelvic angles were increased in a statistically significant manner. Pelvis tilt was decreased in a statistically insignificant manner. The mean of pelvic incidence was not changed and statistically insignificant, and this is matching the fact that pelvic incidence is a constant parameter. The sacral slope was increased in a statistically insignificant manner. Final results showed that 37 had a statistically significant improvement in their ODI >20% at the last visit. Three patients had a poor clinical outcome with ODI scorFinal results showed that 37 had a statistically significant improvement in their ODI >20% at the last visit. Three patients had a poor clinical outcome with ODI score of >20% improvement, and we noticed that the level of pathology was at the level of L4L5, SVA was positive and worsen postoperatively, and also, it is accompanied by decreased lumbar lordosis. Change in ODI means statistically significant improvement when considering sagittal parameters preoperation and during operation.

CONCLUSION: Sagittal balance parameters should be considered in the surgical management of low-grade spondylolisthesis cases to improve their functional outcome.
