Caught in the Crossroad: An Intersectional Examination of African American Women Intimate Partner Violence Survivors’ Help Seeking
Authors: Waller Bernadine Y. , Harris Jalana , Quinn Camille R. 
Published: February 2021

Objectives: African American women are disproportionately impacted by intimate partner violence (IPV)-related homicide. They reflect the second highest prevalence rates and experience the highest rates of murder resulting from IPV victimization. Although most survivors note that they have experienced rejection and anticipatory stigma as barriers to their help seeking, African American women additionally experience racism and racial discrimination as obstacles that may further preclude their help seeking. This systematic review highlights African American women’s experiences of rejection from providers and the effects that it may have upon their ability to secure urgent aid. Method: A dearth of literature examines the subtle ways that African American women survivors experience rejection resulting from the interlocking nature of race, class, and gender oppression. Fundamental to developing more culturally salient interventions is more fully understanding their help-seeking experiences. A systematic review was conducted to provide a critical examination of the literature to understand the intersections of IPV and help-seeking behavior among African American women. A total of 85 empirical studies were identified and 21 were included in the systematic review. The review illuminates both the formal and semiformal help-seeking pathways. Results: We recommend integrating anti-Blackness racist praxis, incorporating African American women’s ways of knowing and centralizing their needs in an effort to improve the health and well-being of this population. Conclusions: Eliminating barriers to more immediately accessing the domestic violence service provision system is key to enhance social work practice, policy, and research with African American female survivors of IPV.

Background: Bone metastasis is a leading cause of the high mortality rate of prostate cancer (PCa), but curative strategies remain lacking. Recent studies suggest long non-coding RNAs (lncRNAs) may be potential targets to develop drugs. However, PCa bone metastasis-specifically-related lncRNAs were rarely reported. This study aimed to identify crucial lncRNAs and reveal their function mechanisms. Methods: GSE32269 and GSE26964 microarray datasets, downloaded from the Gene Expression Omnibus database, were used to analyze differentially expressed genes (DEGs)/lncRNAs (DELs) and miRNAs (DEMs), respectively. Weighted gene co-expression network analysis was performed to screen PCa bone metastasis-associated modules. The co-expression and competing endogenous RNAs (ceRNAs) networks were constructed to identify hub lncRNAs. Univariate Cox regression analysis was conducted to determine their prognostic values. The correlation of lncRNAs with immune infiltrating cells was analyzed by using Tumor IMmune Estimation Resource. Therapeutic drugs were predicted by querying the Connectivity Map (CMap) and the Comparative Toxicogenomics Database (CTD). Results: A total of 18 DELs, 2,614 DEGs and 86 DEMs were screened between bone metastatic and primary PCa samples. Four modules enriched by DEGs were shown to be bone metastasis-associated. LncRNA HCG18 and MCM3AP-AS1 were identified to be important because they existed in both of the co-expression and ceRNA networks (forming the relationship pairs: HCG18/MCM3AP-AS1-KNTC1, MCM3AP-AS1-hsa-miR-508-3p-DTL and HCG18/MCM3AP-AS1-hsa-miR-127-3p-CDKN3). All the genes in these interaction pairs were significantly associated with overall survival of PCa patients. Also, HCG18, MCM3AP-AS1 and their target mRNAs were positively correlated with various tumor-infiltrated immune cells, especially increased M2 macrophages. Valproic acid and trichostatin A may be effective to treat PCa bone metastasis by targeting HCG18 and MCM3AP-AS1. Conclusion: HCG18 and MCM3AP-AS1 that regulate M2 macrophage infiltration may be important targets to treat PCa bone metastasis and improve prognosis.

Published: February 2021

Objectives The aim of this study was to determine the relationship between preoperative nutritional status and wound healing in patients undergoing surgical reconstruction for ischemic tissue loss. Methods The preoperative nutritional status of patients who underwent surgical reconstruction for ischemic tissue loss for the years 2011–2018 was retrospectively estimated using the Controlling Nutritional Status (CONUT) score. Patients were allocated to two groups: Group I, normal nutrition or mild malnutrition (CONUT score ≤4), and Group II, moderate-to-severe malnutrition (CONUT score ≥5). Wound healing was set as the primary endpoint and major amputation and death as the secondary endpoints. The wound healing, limb salvage, and overall survival rates were calculated after two years using the Kaplan–Meier method, and Cox proportional hazards regression analysis was performed to determine which variables were independently associated with these outcomes. Results Forty-eight patients with missing values for the CONUT score were excluded. A total of 174 limbs in 147 patients were studied (Group I: 115 limbs in 100 patients; Group II: 59 limbs in 47 patients). The mean duration of the study was 519 ± 270 days. The Kaplan–Meier curves showed that wound healing in Group I was superior to that in Group II (Group I vs. II: two-year wound healing, 97% vs. 79%; time to 50% wound healing, 83 vs. 150 days, p <  0.001), and multivariate analysis showed that the CONUT score was an independent predictor of wound healing (hazard ratio, 0.63; 95% confidence interval, 0.41–0.98; p =  0.038). Conclusions Patients with better preoperative nutritional status are more likely to experience wound healing earlier than those with excessive malnutrition.

Introduction Assessment of tendon stiffness in vivo traditionally involves maximal muscle contractions, which can be challenging in pain populations. Alternative methods are suggested, although the clinimetric properties are sparse. This study investigated the concurrent validity and the intrarater reliability of two ultrasound-based methods for assessing patellar tendon stiffness. Methods Patellar tendon stiffness was assessed in 17 healthy adults with (a) the dynamometer and B-mode ultrasonography method (DBUS) and (b) the strain elastography method. Correlations between the two methods were analysed using Kendall’s Tau-b. The relative reliability of both methods was evaluated using intraclass correlation coefficient (ICC). The absolute reliability was presented by Bland–Altman plots, standard error of measurement (SEM) and minimum detectable change (MDC). Results No correlation was found between the two methods, irrespective of reference tissue in strain elastography (Kendall’s Tau-b Hoffa = –0.01 (p = 1.00), Kendall’s Tau-b subcutis = 0.04 (p = 0.87)). Tracking of the tendon elongation in the DBUS method had good to excellent relative reliability (ICC = 0.95 (95% confidence interval – CI: 0.85–0.98)) and high absolute reliability (SEM = 0.04 mm (1%), MDC = 0.11 mm (3%)). The strain elastography method had good to excellent relative reliability, regardless of reference tissue (ICC Hoffa = 0.95 (95% CI: 0.86–0.98), ICC subcutis = 0.94 (95% CI: 0.82–0.98)), but low absolute reliability (SEM Hoffa = 0.06 (20%), MDC Hoffa = 0.18 (60%), SEM subcutis = 0.12 (41%), MDC subcutis = 0.32 (110%)). Conclusions No concurrent validity existed for DBUS and strain elastography, suggesting that the two methods measure different tendon properties. The overall reliability for the DBUS method was high, but the absolute reliability was low for strain elastography stiffness ratios. Therefore, the strain elastography method may not be recommended for tracking differences in patellar tendon stiffness in healthy adults.

Published: February 2021

Background The primary aim of this study was to compare the long-term functional outcome of midshaft clavicle fracture fixation for delayed (≥3 month) and non-union (≥6 month) compared to a matched cohort of patients that achieved union with non-operative management. The secondary aim was to assess cost-effectiveness of fixation. Methods A consecutive series of patients over 10-years were retrospectively reviewed using the QuickDASH, Oxford Shoulder Score and EuroQol five-dimension summary index (EQ-5D). These patients were compared to a matched cohort that achieved union after non-operative management using propensity score matching. Results Sixty patients (follow-up 79%, n = 60/76) at 4.1 years post-operative (1.1–10.0 years) had a QuickDASH of 16.5 (95% CI 11.6–21.5), Oxford Shoulder Score 41.5 (39.0–44.1) and EQ-5D 0.7621 (0.6822–0.8421). One in five patients were dissatisfied with their final outcome ( n = 13/60). Functional outcome was inferior following fixation when compared to patients that united with non-operative management (QuickDASH 16.5 vs. 5.5, p < 0.001 and EQ-5D 0.7621 vs. 0.9073, p = 0.001). However, significant improvements were found when compared to pre-operative scores (QuickDASH p < 0.001 and EQ-5D p < 0.001). The cost per QALY for fixation was £5624.62 for the study cohort. Conclusions Clavicle fixation for delayed and non-union is a cost-effective intervention but outcomes are worse compared to patients that unite with non-operative management.

Background The purpose of our study was to investigate the influence of the different rugby playing positions on return to sports, functional outcomes, and recurrences after an arthroscopic Bankart repair. Methods A total of 88 rugby players were treated for anterior shoulder instability in our institution between 2010 and 2018. Functional outcomes, return to sports, recurrences, complications, and revisions rates were evaluated according to the playing position. Results Overall, 73.8% of the patients returned to rugby and 60% returned at the same level as before the injury. The tight forwards and outside backs experienced a significant decrease in their competitive level after surgery, and showed the lowest functional outcomes. The tight forwards and outside backs showed a statistically significant increase in recurrence and revision rates, and an OR for recurrence of 12.8 and 9.6, respectively. Discussion The playing position significantly influenced return to sports and recurrences after an arthroscopic Bankart repair in competitive rugby players. Specifically, the tight forwards and outside backs have returned to a lower level than they had before surgery, showed the lowest functional outcomes, and a significant increase in recurrences and revisions rates than the other groups.

Objective Joint injuries may lead to degeneration of cartilage tissue and initiate development of posttraumatic osteoarthritis. Arthroscopic surgeries can be used to treat joint injuries, but arthroscopic evaluation of articular cartilage quality is subjective. Fourier transform infrared spectroscopy combined with fiber optics and attenuated total reflectance crystal could be used for the assessment of tissue quality during arthroscopy. We hypothesize that fiber-optic mid-infrared spectroscopy can detect enzymatically and mechanically induced damage similar to changes occurring during progression of osteoarthritis. Design Bovine patellar cartilage plugs were extracted and degraded enzymatically and mechanically. Adjacent untreated samples were utilized as controls. Enzymatic degradation was done using collagenase and trypsin enzymes. Mechanical damage was induced by (1) dropping a weight impactor on the cartilage plugs and (2) abrading the cartilage surface with a rotating sandpaper. Fiber-optic mid-infrared spectroscopic measurements were conducted before and after treatments, and spectral changes were assessed with random forest, partial least squares discriminant analysis, and support vector machine classifiers. Results All models had excellent classification performance for detecting the different enzymatic and mechanical damage on cartilage matrix. Random forest models achieved accuracies between 90.3% and 77.8%, while partial least squares model accuracies ranged from 95.8% to 84.7%, and support vector machine accuracies from 91.7% to 80.6%. Conclusions The results suggest that fiber-optic Fourier transform infrared spectroscopy attenuated total reflectance spectroscopy is a viable way to detect minor and major degeneration of articular cartilage. Objective measures provided by fiber-optic spectroscopic methods could improve arthroscopic evaluation of cartilage damage.

Published: February 2021

Introduction: Detrusor underactivity (DUA) is a highly prevalent and poorly understood disease in urology practice. Conservative treatment in the form of clean intermittent catheterization (CIC) and pharmacotherapy are in use for DUA without good results. Endoscopic prostate surgery was initially considered ineffective in such patients. But a recent series of retrospective studies showed promising results of surgery in DUA. Therefore, we conducted this prospective study to evaluate success of endoscopic prostatic surgery in a patient with DUA. Materials and methods: This is prospective observational study of 50 patients, satisfying the inclusion criteria, at Ruby Hall Clinic, Pune, conducted between March 2017 and March 2019. Inclusion criteria are that the patients are male, aged > 50 years; urodynamically diagnosed with DUA; a bladder contractility index < 90 with associated bladder outlet obstruction index (BOOI) between 20–40 (equivocal) or > 40 (obstruction), who presented with lower urinary tract symptoms and poor flow ( Qmax < 10 ml/s in a voided volume of >150 ml. Patients were excluded from the study if they had DUA due to neurological causes or spinal trauma, an acontractile detrusor, and were < 50 years. Results: The follow-up period for each patient was 12 months. The mean international prostate specific score reduced from 24.82 ± 2.74 preoperatively to 4.4 ± 1.85 postoperatively. Mean quality of life score reduced from 4.06 ± 0.68 to 0.82 ± 0.62. Mean Qmax increased from 6.26 ±1.46 ml/s to 12.22 ±1.6 ml/s. Mean post-void residual urine volume reduced form 241.9 ±74.9 to 77.3 ±20.75. All of these were statistically significant with a p value < 0.00001. Conclusion: Transurethral resection of the prostate (monopolar/laser) to reduce BOO should be considered as an alternative, viable treatment option in men with DUA. Preoperative counselling and postoperative follow-up are crucial in the management of such patients. Level of evidence:

Published: February 2021

Background: Although not infrequent, publications on high-pressure chronic urinary retention (HPCR) are limited. Lack of awareness of this condition can lead to delayed diagnosis and suboptimal treatment. This systematic review aimed to describe the clinical characteristics and outcome of HPCR. Methods: Keywords were searched in PubMed, Scopus, EMBASE, LILACS, Cochrane-CENTRAL, APAMED Central and Google Scholar. Relevant articles were added from the list of references of eligible articles. Studies describing any two of the characteristic features related to HPCR were included. Qualitative analysis was performed using the available data. Results: Eight prospective studies with 271 patients ( Mage=66.4 years, range 14–89 years; 263 males) were identified. The commonest presentation was tense painless palpable bladder (99.6%). Late-onset nocturnal enuresis was reported in 68.4%, and resistant hypertension was reported in 41.6%. Elevated levels of serum creatinine were identified in 43–81%. Benign prostatic hyperplasia (64.1%) was the commonest aetiology followed by prostatic malignancy (22.6%). A satisfactory response was seen following the definitive treatment of the underlying aetiology. Initial bladder decompression reversed adverse cardiovascular changes and improved renal function but resulted in post-obstructive diuresis. Heterogeneity of the reported data in available studies was a major limitation. Conclusions: Late-onset nocturnal enuresis, a tense painless and non-tender palpable bladder and treatment-resistant hypertension are important clinical findings which would raise the suspicion of HPCR in the clinical setting. Urinary tract ultrasonography showing upper-tract dilatation and raised serum creatinine support the diagnosis. Definitive treatment targeting the underlying aetiology following careful decompression of the bladder showed satisfactory outcomes. Level of evidence: Level 2a(-).
Telling Children with Perinatal HIV About Their HIV Serostatus: Healthcare Workers’ Practices and Barriers to Disclosing in a South African Rural Health District
Authors: Madiba Sphiwe , Diko Cynthia 
Published: February 2021

In South Africa, caregivers and healthcare workers (HCWs) lack confidence and skills to disclose to children with perinatal HIV (PHIV). Moreover, existing disclosure guidelines do not provide strategies on how to approach disclosure. Although the caregiver has been endorsed as a responsible person to disclose to the child, the involvement of HCWs in the process is critical. Yet research suggests that many HCWs are reluctant to perform disclosure. This study examines the involvement in, practices of, and barriers against HCWs’ disclosing to children with PHIV. Methods: We conducted 8 focus group discussions with a total of 51 HCWs comprising nurses, lay counsellors, social workers, and dieticians. The HCWs were selected from 23 health facilities in a rural South African health district by purposive sampling. Data were transcribed verbatim, and data analysis followed qualitative thematic analysis. Results: A high proportion of HCWs had no formal training in pediatric disclosure and some had never disclosed to children. Those who routinely disclosed approached disclosure as an ongoing process that unfolded over time. They ensured caregiver readiness as a necessary step in the disclosure process. The main barriers for HCWs to participate fully in the disclosure process were the lack of relevant disclosure guidelines, inadequate disclosure skills, and a shortage of skilled staff. Inadequate skills affected the confidence of the HCWs to disclose, while a lack of standardized disclosure guidelines and HCWs’ reliance on personal experience during disclosure resulted in confusion and uncertainty among them due to the inconsistencies in their approach to disclosure. Conclusion: This study confirms the urgent need to train HCWs to attain skills and confidence in disclosure. Training HCWs in standardized disclosure counselling would lead to an increase in the rate of disclosure to children. It is essential that the district adapt the disclosure guidelines to the local context for use in health facilities.

Study Design: Retrospective cohort. Objective: Provide a comparison of surgical approach in the treatment of degenerative cervical myelopathy in patients with OPLL. Methods: A national database was queried to identify adult (≥18 years) patients with OPLL, who underwent at least a 2-level cervical decompression and fusion for cervical myelopathy from 2012-2014. A propensity-score-matching algorithm was employed to compare outcomes by surgical approach. Results: After propensity-score matching, 627 patients remained. An anterior approach was found to be an independent predictor for higher inpatient surgical complications(OR 5.9), which included dysphagia:14%[anterior]vs.1.1%[posterior] P-value < 0.001, wound hematoma:1.7%[anterior]vs.0%[posterior] P-value = 0.02, and dural tear:9.4%[anterior]vs.3.2%[posterior] P-value = 0.001. A posterior approach was an predictor for longer hospital length of stay by nearly 3 days(OR 3.4; 6.8 days[posterior]vs.4.0 days[anterior] P-value < 0.001). The reasons for readmission/reoperation did not vary by approach for 2-3-level fusions; however, for >3-level fusions, patients with an anterior approach more often had respiratory complications requiring mechanical ventilation( P-value = 0.038) and required revision fusion surgery( P-value = 0.015). Conclusions: The national estimates for inpatient complications(25%), readmissions(9.9%), and reoperations(3.5%) are substantial after the surgical treatment of multi-level OPLL. An anterior approach resulted in significantly higher inpatient surgical complications, but this did not result in a longer hospital length of stay and the overall 90-day complication rates requiring readmission or reoperation was similar to those seen after a posterior approach. For patients requiring >3-level fusion, an anterior approach is associated with significantly higher risk for respiratory complications requiring mechanical ventilation and revision fusion surgery. Precise neurological complications and functional outcomes were not included in this database, and should be further assessed in future studies.
