Mental health among the Hmong population in the U.S.: A systematic review of the influence of cultural and social factors
Authors: Vang Cindy , Sun Fei , Sangalang Cindy C 
Published: July 2020

Summary As refugees of the war in Southeast Asia, Hmong experienced various traumatic events. Evidence suggests the persistence of psychiatric disorders related to trauma in refugees even after prolonged resettlement in their host country. This systematic review aimed to summarize the mental health literature on the Hmong population with a focus on cultural and social factors. The databases PsycINFO, PsycARTICLES, Social Services Abstracts, Web of Science, and PubMed were reviewed for peer-reviewed articles published up to April 2018. Forty articles were included in the final review. Findings Results highlight three primary themes: (1) mental health outcomes were associated with a variety of premigration and postmigration factors, (2) group and community-based treatment and interventions provided promising results, and (3) barriers to mental health care were primarily stigma, communication challenges, discrimination, and mental health literacy. The results of this systematic review shed light on the limited and small studies with the Hmong population. Applications Implications for social work and culture-sensitive research, practice, and policymaking for this population are discussed.

Published: July 2020

Background: The aim of this study was to examine the relationship between diet quality and weight gain in kidney transplant recipients from pretransplant baseline through posttransplant at 3 months and 1 year. Methods: Data from a prospective, observational cohort study of kidney transplant patients (n = 26) were analyzed. Participants were adult (aged 18-65 years), living donor kidney transplant recipients who were participating in a prospective body composition study. Body weight, body mass index, dietary intake, and Healthy Eating Index scores were used to assess changes in weight, nutrient intake, and diet quality. Findings: At the time of kidney transplantation, 42% (n = 11) were obese and 27% (n = 7) were overweight. Weight significantly increased from transplantation to 12 months (mean [SD]: 83 [18] kg and 90 [18] kg, respectively; mean change 8.4%, P = .002). At 12 months posttransplant, dietary fat intake significantly increased ( P = .033). Body weight was strongly correlated with total dietary fat intake ( r = 0.56, P = .003). The Healthy Eating Index total scores at baseline and 1-year posttransplant were not significantly different (45.75 [14.99] and 42.59 [12.70]). Likewise, component scores did not change from pretransplant to posttransplant. Discussion: Diet quality of transplant recipients was poor both before and after transplantation. Using the Healthy Eating Index confirmed that improvements in food intake are needed. Further research is warranted to identify dietary recommendations for the prevention of excessive weight gain and the potential adverse health complications following kidney transplantation.

Published: July 2020

Background: Triple-negative breast cancer encompasses heterogeneous subtypes. Neoadjuvant chemotherapy is ineffective against some triple-negative breast cancers, while others show a favorable prognosis despite chemoresistance. Methods: A total of 51 cases with stages I and II triple-negative breast cancer were analyzed; 34 triple-negative breast cancers treated with neoadjuvant chemotherapy were divided into “good responders” (n = 22), showing therapeutic effect G2b or G3 in surgical specimens, and “poor responders” with therapeutic effect G0, G1a, G1b, and G2a (n = 12). Neoadjuvant chemotherapy was spared in 17 cases (non-neoadjuvant chemotherapy group). Apocrine-type triple-negative breast cancer was defined as triple-negative breast cancer immunoreactive for both androgen receptor and forkhead-box protein A1. Triple-negative breast cancer other than apocrine-type (n = 16) and special types (myoepithelial, medullary, adenoid cystic, and spindle cell carcinomas, n = 6) was categorized as basal-like subtype (n = 29). Prognosis was evaluated in each category. Results: Neoadjuvant chemotherapy provoked significant effects against basal-like triple-negative breast cancer with high Ki-67 labeling (≧50%), and tumor-infiltrating lymphocytes predicted high chemosensitivity. Neoadjuvant chemotherapy was avoidable in triple-negative breast cancer of apocrine- and special types showing low (<50%) Ki-67 labeling. Ten (59%) lesions in the non-neoadjuvant chemotherapy group belonged to the apocrine-type. When clinical complete remission shown by contrast-enhanced magnetic resonance imaging was reached in the course of neoadjuvant chemotherapy against basal-like triple-negative breast cancer, the neoadjuvant chemotherapy period was shortened in 14 (64%) of 22 good responders. Disease-free and overall survival rates were excellent in all groups. Conclusions: The following 2 hypothetical proposals should be proven by large-scale clinical trials. Immunohistochemical recognition of apocrine-type triple-negative breast cancer with low Ki-67 labeling is important for avoiding ineffective/unnecessary neoadjuvant chemotherapy. By employing appropriate clinical imaging, period-shortening is achievable in basal-like triple-negative breast cancer with high Ki-67 labeling.

Published: July 2020

Objectives: To investigate the safety and efficacy of a stent combined with a linear strand of 125I seeds to treat malignant cancer–associated venous obstruction. Methods: We retrospectively analyzed the data of 57 patients with malignant cancer–associated venous obstruction. Nineteen patients underwent the placement of a stent combined with a linear strand of 125I seeds (group A), and 38 patients underwent the placement of a bare stent (group B). The following parameters were compared between the 2 groups of patients: symptom relief rate, duration of venous patency, survival time, quality of life, and adverse events. Results: A total of 34 stents and 527 seeds were implanted in group A, while a total of 57 stents were implanted in group B. The surgery success rate was 96.5%, and no serious complication related to the surgery was reported. Symptoms of venous obstruction improved significantly after surgery. The score of group A decreased from 14.74 ± 0.562 points before surgery to 2.79 ± 1.357 points after surgery( P < .001), and the score of group B decreased from 13.79 ± 1.398 points before surgery to 5.55 ± 3.674 points after surgery ( P < .001). The patency rate of group A was significantly higher than that of group B at 1 to 6 months after surgery (100%, 84.2%, 68.4%, 63.2%, 36.8%, 21.1% vs 68.4%, 23.7%, 18.4%, 7.9%, 5.3%, 2.6%, respectively; P < .05). Before treatment, there was no statistically significant difference in the Karnofsky Performance Status (KPS) score between the groups ( P = .791). After 1 to 6 months of treatment, the KPS score was significantly higher in group A than in group B ( P = .013). The median patency duration in groups A and B was 125 days (95% CI: 80.018-169.982) and 35 days (95% CI: 20.501-49.499), respectively ( P < .001). The median survival time of group A was 155 days (95% CI: 110.406-199.594), and that of group B was 98 days (95% CI: 55.712-140.288; P = .325). Multivariate analysis showed that the implantation of a stent combined with a linear strand of 125I seeds and the KPS score (≥80 points) were independent factors of long-term patency after stent placement. Conclusions: The placement of a stent combined with a linear strand of 125I seeds is a safe and effective treatment for venous obstruction caused by malignant tumors. This treatment provides prolonged patency compared with the placement of bare stent, and while it does not significantly improve the survival time of patients, it can improve their quality of life.
Barriers to uptake of the hip fracture core outcome set: An international survey of 80 hip fracture trialists
Authors: Fletcher Jessica , Sheehan Katie Jane , Smith Toby O 
Published: July 2020

Background: Core outcome sets are an agreed recommendation to inform the selection of outcome measures in clinical trials. There has been low uptake of the 2014 hip fracture core outcome set. The reasons for this remain unclear. The aim of this study was to understand the reasons for the non-adoption and approaches to increase adoption of the hip fracture core outcome set. Methods: Randomised controlled trials from PubMed (2017–2019) and ClinicalTrials.gov (2015–2019) were identified. Corresponding authors for each identified trial (n = 302) were surveyed using five questions on awareness of the hip fracture core outcome set, reasons for non-adoption and approaches to increase adoption. Data were analysed descriptively using frequencies, mean values and standard deviations. Results: Fifty-four percent of the respondents (n = 43) were aware of the concept of core outcome set. Only 15% (n = 12) based the outcome measure selection on the 2014 hip fracture core outcome set. Key reasons for non-adoption included the following: authors being unaware and perceived inappropriateness to their trial design. Eighty-six percent (n = 69) of respondents agreed to the need for increased awareness of core outcome sets through research training, academic and clinical journal requirements, and funding or publication stipulations. Eighty-eight percent (n = 70) of respondents indicated the current core outcome set required revision to focus on trials investigating people with cognitive impairment, caregivers, rehabilitation, surgical interventions and anaesthetic trial designs. Conclusion: Barriers to the adoption of the hip fracture core outcome set centre on education, awareness of the core outcome sets and applicability to the breath of hip fracture trial designs. Further consideration should be made to address these, to improve the harmonisation of outcome measures across hip fracture trials.

Published: July 2020

Background: The management of data on coronary artery disease (CAD) plays a significant role in controlling the disease and reducing the mortality of patients. The diseases registries facilitate the management of data. Objective: This study aimed to identify the attributes of hospital-based CAD registries with a focus on key registry processes. Method: In this systematic review, we searched for studies published between 2000 and 2019 in PubMed, Scopus, EMBASE and ISI Web of Knowledge. The search terms included coronary artery disease, registry and data management (MeSH terms) at November 2019. Data gathering was conducted using a data extraction form, and the content of selected studies was analysed with respect to key registry processes, including case finding, data gathering, data abstracting, data quality control, reporting and patient follow-up. Results: A total of 17,604 studies were identified in the search, 55 of which were relevant studies that addressed the 21 registries and were selected for the analysis. Results showed that the most common resources for case finding included admission and discharge documents, physician’s reports and screening results. Patient follow-up was mainly performed through direct visits or via telephone calls. The key attributes used for checking the data quality included data accuracy, completeness and definition. Conclusion: CAD registries aim to facilitate the assessment of health services provided to patients. Putting the key registry processes in place is crucial for developing and implementing the CAD registry. The data quality control, as a CAD registry process, requires developing standard tools and applying appropriate data quality attributes. Implications: The findings of the current study could lay the foundation for successful design and development of CAD registries based on the key registry processes for effective data management.

Published: July 2020

Study Design: Retrospective study of all patients presented at our emergency department after an accident while riding an e-scooter between 15 June 2019 and 15 December 2019. Out of this group, we subgrouped all patients with injuries to the head and neck area. Objective: Shared e-scooter systems have recently been introduced in many big cities worldwide and are becoming increasingly popular. This retrospective study aimed to give a detailed overview of clinical data on consequences of e-scooter accidents, with particular attention to the maxillofacial point of view. Methods: We performed a single-center retrospective study of all patients presented at our emergency department after an accident while riding an e-scooter between June 15, 2019 and December 15, 2019. Results: Within the observation period, 43 patients (mean age of 32 years; range: 17-64 years) suffered from an accident while riding an e-scooter. Of these, 25 patients (58%) required maxillofacial treatment whereby 9 patients (36%) suffered a fracture (56% fracture of the mandible; 33% fracture of the nasal bone; 11% fracture of the maxilla). Six patients required maxillofacial surgical treatment. Twelve patients (28%) stated to have been driving under the influence of alcohol at the time of the accident (blood alcohol level between 0.77 g/L and 2.32 g/L). None of the patients used body protection, and only one patient wore a helmet (2%). Conclusions: With the introduction of shared e-scooter systems, health-care facilities are faced with an increasing number of accidents related to the use of e-scooters, suffering from a high percentage of injuries in the maxillofacial region. Facial injuries might be reduced by the mandatory use of a helmet with faceguard. The trauma mechanism, in particular, seems to differ from other common trauma cases and needs to be examined more closely.

Introduction: Resveratrol (RES) exhibits estrogen-like effects and has potential applications to treatment of osteoporosis caused by estrogen deficiency; however, the specific mechanism of action of RES remains unclear. Here, we examined the therapeutic effects of RES on ovariectomized (OVX) rats with osteoporosis and determined the underlying mechanism. Methods: We established an OVX rat model to study osteoporosis caused by estrogen deficiency. The treatment groups were given orally with RES (50, 100, and 200 mg/day), the estrogen group received 0.8 mg/kg E2 daily via oral route, and the sham-operated and control groups received an equivalent dose of sodium carboxymethylcellulose orally. After 12 weeks of treatment, we used real-time quantitative polymerase chain reaction (PCR) and Western blot analysis to measure the gene and protein expression of miR-92b-3p, Nox4, NF-κBp65, IκB, BMP2, Smad7, and RUNX-2 in bone tissues. Right femur structural parameters were evaluated by micro-CT. Dual-energy X-ray 4500 W was used to determine systemic bone mineral density (BMD). Enzyme-linked immunosorbent assay (ELISA) kits were used to determine the serum levels of bone alkaline phosphatase (BALP), osteoprotegerin (OPG), anti-tartrate acid phosphatase-5b (PTRA5b), and carboxylated terminal peptide (CTX-I). The rat femoral bone specimens were stained using hematoxylin and eosin for pathological examination Results: We observed increased levels of serum estrogen in both ovaries, elevated miR-92b-3p levels in bone tissues, reduced levels of Nox4, NF-κBp65, p-IκB-a, and cathepsin K, and elevated gene and protein expression of BMP2, Smad7, and RUNX-2 in the OVX rat model of osteoporosis after treatment with RES. Elevated levels of BALP, OPG, ALP, and BMD along with reduced levels of TRAP-5b and CTX-I were also observed. The structural model index (SMI) and the trabecular space (Tb. Sp) decreased, while the trabecular thickness (Tb. Th), bone volume fraction (BV/TV), trabecular number (Tb.N), and tissue bone density (Conn.D) increased, thereby improving osteoporosis induced by estrogen deficiency in both ovaries. Conclusion: Cathepsin K expression and Nox4/NF-κB signaling pathway were suppressed by the elevated expression of miR-92b-3p. This inhibition was pivotal in the protective effect of RES against osteoporosis induced by estrogen deficiency in both ovaries. Thus, RES efficiently alleviated osteoporosis induced by estrogen deficiency in rats.

Published: July 2020

Background: A safe and simple procedure to evaluate functional instability due to anterior cruciate ligament (ACL) deficiency (ACLD) has not been established. The angle of trunk backward tilting, which is known as a posture at risk for ACL injuries, could be used as a parameter to evaluate functional instability due to ACLD. Purpose: To measure the backward tilt angle of the trunk with participants standing upright on 1 leg and to investigate its usefulness to quantitatively evaluate functional instability due to ACLD. Study Design: Cohort study (diagnosis); Level of evidence, 3. Methods: Our cohort included 50 participants with unilateral ACLD and 40 participants with bilateral healthy knees. The trunk backward tilt (TBT) test was conducted as follows: the participant was asked to maximally tilt the trunk backward in a single-leg standing position, while forward tilt of the index leg was blocked with a custom-made device. The TBT angle was measured using a side-view photograph. Subjective knee instability during the test was recorded using a visual analog scale (VAS). The relative and absolute reliability of the TBT test were verified in a sample of healthy participants and those with ACLD, and comparisons between indicators were performed. Multiple regression analysis was performed with the injured/uninjured side ratio (I/U ratio) of the TBT angle as the dependent variable and the following independent variables: (1) I/U ratio of knee extension muscle strength, (2) I/U ratio of knee flexion muscle strength, (3) side-to-side difference (SSD) of the KT-1000 arthrometer measurement, (4) sex, and (5) SSD of the VAS score. Results: The TBT test had high reliability among healthy participants and those with ACLD. The TBT angle was significantly smaller and the VAS score was significantly higher on the injured side compared with the uninjured side and with healthy knees ( P < .001 for all). Among the independent variables, the SSD of the VAS score had a negative influence on the I/U ratio of the TBT angle ( R 2 = 0.59; P < .001). Conclusion: The TBT test is a simple, safe, and reliable method for quantitatively evaluating functional instability due to ACLD under weightbearing conditions that reflect subjective knee instability. The test will provide an index of treatment outcomes and return to sports through additional objective measurements before and after ACL reconstruction.

AbstractCongenital erythropoietic porphyria (CEP) is an inborn error of heme synthesis resulting from uroporphyrinogen III synthase (UROS) deficiency and the accumulation of nonphysiological porphyrin isomer I metabolites. Clinical features are heterogeneous among patients with CEP but usually combine skin photosensitivity and chronic hemolytic anemia, the severity of which is related to porphyrin overload. Therapeutic options include symptomatic strategies only and are unsatisfactory. One promising approach to treating CEP is to reduce the erythroid production of porphyrins through substrate reduction therapy by inhibiting 5-aminolevulinate synthase 2 (ALAS2), the first and rate-limiting enzyme in the heme biosynthetic pathway. We efficiently reduced porphyrin accumulation after RNA interference–mediated downregulation of ALAS2 in human erythroid cellular models of CEP disease. Taking advantage of the physiological iron-dependent posttranscriptional regulation of ALAS2, we evaluated whether iron chelation with deferiprone could decrease ALAS2 expression and subsequent porphyrin production in vitro and in vivo in a CEP murine model. Treatment with deferiprone of UROS-deficient erythroid cell lines and peripheral blood CD34+-derived erythroid cultures from a patient with CEP inhibited iron-dependent protein ALAS2 and iron-responsive element–binding protein 2 expression and reduced porphyrin production. Furthermore, porphyrin accumulation progressively decreased in red blood cells and urine, and skin photosensitivity in CEP mice treated with deferiprone (1 or 3 mg/mL in drinking water) for 26 weeks was reversed. Hemolysis and iron overload improved upon iron chelation with full correction of anemia in CEP mice treated at the highest dose of deferiprone. Our findings highlight, in both mouse and human models, the therapeutic potential of iron restriction to modulate the phenotype in CEP.
Expansions and contractions in gene families of independently-evolved blood-feeding insects
Authors: Freitas Lucas , Nery Mariana F. 
Published: July 2020

AbstractBackgroundThe blood-feeding behavior evolved multiple times in Insecta lineages and it represents an excellent opportunity to study patterns of convergent molecular evolution regarding this habit. In insects the expansion of some gene families is linked with blood-feeding behavior, but a wide study comparing the evolution of these gene families among different lineages is still missing. Here we gathered genomic data from six independently-evolved hematophagous lineages, aiming to identify convergent expansions and/or contractions of gene families in hematophagous lineages of insects.ResultsWe found four rapidly evolving gene families shared by at least two hematophagous independently-evolved lineages, including a heat-shock and a chemosensory protein. On the expression of these four rapidly evolving gene families we found more genes expressed in mated individuals compared with virgin individuals in rapidly-expanded families and more genes expressed in non-blood-feeding individuals compared with blood-feeding individuals in rapidly-contracted families.ConclusionOur results reveal a new set of candidate genes to be explored in further analysis to help the development of new strategies to deal with blood-feeding vectors and also presents a new perspective to study the evolution of hematophagy identifying convergent molecular patterns.
