BACKGROUND: Sexual health is a taboo issue in some societies. Limited assessments were conducted during nursing care in mental health services. It is unknown whether psychiatric nurses' competencies would be enhanced through short training courses. AIMS: The present study employed a quasi-experimental design to evaluate the effectiveness of an 8-hour sexual health care training for psychiatric nurses to improve sexual health knowledge, attitude, and self-efficacy in a teaching psychiatric hospital in southern Taiwan. METHOD: Volunteered psychiatric nurses were randomly assigned to the experimental or control group. The 8-hour training program contained sexual health knowledge and attitudes, case discussion, role play, and sexual identity or harassment issues. Each nurse received a pretest and a posttest in the 1-month period between August and September 2019. Descriptive and multivariate statistical analyses were used to evaluate the effects. RESULTS: Among the 75 psychiatric nurses, 43 were in the control group and 32 were in the experimental group. The two groups were not significantly different in the working year, gender, education, marriage, and other psychosocial variables. After the training, the overall performance of sexual health care knowledge, attitudes, and self-efficacy of the experimental group improved significantly than the controls. CONCLUSIONS: The sexual health care training program enhanced psychiatric nurses' confidence and generally improved their sexual knowledge and attitudes. It is suggested that sexual health care needs to be highlighted during in-job training to augment the well-being and life quality of psychiatric patients. [ABSTRACT FROM AUTHOR]

BACKGROUND: Green lacewings (Neuroptera: Chrysopidae) are important beneficial insects that can be raised on artificial diets for culturing experimental lines. An encapsulation method for embedding a core material within a sealed shell to prevent evaporation and biological contamination is crucial for providing food to these predatory insects. RESULTS: This study presents a new encapsulation process to mass produce a core–shell microcapsule diet for rearing Mallada basalis (Walker) (Neuroptera: Chrysopidae). This new process provided consistent quality control and effectiveness of the microcapsule diet (742.1 ± 11.3 μm in diameter and 44.2 ± 1.9 μm in shell thickness). Furthermore, significant differences were measured in larval development (24.0 ± 0.3 vs. 20.1 ± 0.6 days) and fecundity (465 ± 65.05 vs. 678 ± 54.91 eggs) on comparing the development of M. basalis larvae fed the old and new diets. Survival rates increased in both single‐ and group‐rearing tests for adults fed the new diet during the larval stages. Neither diet affected predation rates for M. basalis larvae preying on nymphs of Aphis gossypii Glover (Hemiptera: Aphididae) and Bemisia argentifolli Bellows and Perring (Hemiptera: Aleyrodidae). CONCLUSION: Compared with the old process, the new encapsulation process requires reduced effort during preparation, and reduces the weight, cost and space occupied by the equipment. The results of this study suggest that this new spherical microcapsule artificial diet is suitable for group‐rearing of M. basalis and may be appropriate for mass‐rearing of other types of carnivorous insects. © 2019 Society of Chemical Industry [ABSTRACT FROM AUTHOR]

Purpose: A growing body of evidence shows an association between DNA repair protein genotypes and susceptibility to various cancers. However, few studies have assessed the contribution of the genotype of XRCC3, a homologous repair gene, to the occurrence or prognosis of childhood acute lymphoblastic leukemia (ALL). In this study, we investigated the contribution of seven XRCC3 polymorphisms to childhood ALL.Patients and methods: We recruited 266 patients with childhood ALL and 266 healthy controls. Genomic DNA was isolated from peripheral blood samples. The XRCC3 rs1799794, rs45603942, rs1799796, rs861530, rs28903081, rs861539, and rs3212057 polymorphic genotypes of each subject were determined through conventional polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis.Results: Genotypes with the rs861539 polymorphism were significantly associated with the risk of childhood ALL. The allelic distribution analyses suggested a significant association between the T allele at rs861539 with an increased risk of childhood ALL in the Taiwanese population. Polymorphic variants of XRCC3 at rs3212057 or rs28903081 did not exist in the study population. XRCC3 rs1799794, rs45603942, rs1799796, and rs861530 were not significantly associated with the risk of childhood ALL in the Taiwanese population.Conclusion: Our findings suggest that XRCC3 genotypes with polymorphisms at rs861539 may play a role in determining individual susceptibility to childhood ALL in this Taiwanese population. The polymorphism may be a potential detector and predictor of childhood ALL. [ABSTRACT FROM AUTHOR]

A series of novel benzimidazole derivatives were designed and synthesised based on the structures of reported oral available ALK inhibitor and HDAC inhibitor, pracinostat. In enzymatic assays, compound 3b , containing a 2-acyliminobenzimidazole moiety and hydroxamic acid side chain, could inhibit both ALK and HDAC6 (IC 50 = 16 nM and 1.03 µM, respectively). Compound 3b also inhibited various ALK mutants known to be involved in crizotinib resistance, including mutant L1196M (IC 50 , 4.9 nM). Moreover, 3b inhibited the proliferation of several cancer cell lines, including ALK-addicted H2228 cells. To evaluate its potential for treating cancers in vivo , 3b was used in a human A549 xenograft model with BALB/c nude mice. At 20 mg/kg, 3b inhibited tumour growth by 85% yet had a negligible effect on mean body weight. These results suggest a attracting route for the further research and optimisation of dual ALK/HDAC inhibitors.

Background/aim: The capacity for non-homologous end-joining (NHEJ) repair plays a pivotal role in maintaining genome stability and in carcinogenesis. However, there is little literature on the involvement of NHEJ-related genes in childhood acute lymphocytic leukemia (ALL). Our study aimed to elucidate the impact of polymorphisms of X-ray repair cross-complementing group 4 (XRCC4) (rs6869366, rs2075685, rs2075686, rs28360071, rs3734091, rs28360317, rs1805377), XRCC5 (rs828907, rs11685387, rs9288518), XRCC6 (rs5751129, rs2267437, rs132770, rs132774), XRCC7 rs7003908, and DNA ligase IV (LIG4) rs1805388, on the odds of childhood ALL., Materials and Methods: Genotypes NHEJ-related genes of 266 cases and 266 controls were determined, and the genotype-phenotype correlation was investigated by examining mRNA transcript expression and the capacity for overall and precise NHEJ repair., Results: The variant genotypes of XRCC4 rs3734091, rs28360071, XRCC5 rs828907, and XRCC6 rs5751129 were significantly associated with increased odds of childhood ALL. Further analysis based on susceptibility genotypes showed no significant differences in mRNA transcript expression levels among childhood ALL cases with various putative high-risk genotypes, except XRCC6 rs5751129. Moreover, the overall NHEJ repair capacity was similar among carriers of different XRCC4, XRCC5, and XRCC6 genotypes. However, it is worth noting that individuals carrying the variant C allele at XRCC6 rs5751129 exhibited lower precise NHEJ repair capacity compared to those with the wild-type T allele., Conclusion: Our study identified significant associations between XRCC4 rs3734091, rs28360071, XRCC5 rs828907, and XRCC6 rs5751129 genotypes and childhood ALL. Notably, lower transcriptional expression and reduced precise NHEJ repair capacity were observed in patients carrying the C allele of XRCC6 rs5751129. Further investigations are required to gain deeper insights into childhood ALL development., (Copyright © 2024, International Institute of Anticancer Research (Dr. George J.

Background/aim: Interleukin 8 (IL-8) is highly expressed in refractory acute lymphocytic leukemia (ALL) cells. This study aimed to investigate the contribution of IL-8 polymorphisms to the risk of childhood ALL., Materials and Methods: The genotypes of IL-8 rs4073, rs2227306, rs2227543, and rs1126647 were determined in 266 childhood ALL cases and 266 controls using the PCR-RFLP method. Additionally, we assessed whether the interactions of these genotypes with age and sex contributed to childhood ALL risk., Results: The distributions of genotypic and allelic frequencies of IL-8 rs4073, rs2227306, rs2227543, and rs1126647 were not significantly different between childhood ALL cases and controls (all p>0.05). However, carriers of the variant AA genotype at IL-8 rs4073 had a significantly higher risk of childhood ALL among those aged ≤3.5 years and among girls (OR=2.39 and 3.32, 95%CI=1.21-4.73 and 1.51-7.30, p=0.0182 and 0.0042, respectively). In the stratification analysis, IL-8 rs4073 AT and AA genotypes were associated with higher childhood ALL risk classification and shorter survival time (OR=2.21 and 4.13, 95%CI=1.29-3.78 and 1.87-9.10, p=0.0054 and 0.0002, respectively). There was no positive association for rs2227306, rs2227543, or rs1126647 (all p>0.05)., Conclusion: The A allele of IL-8 rs4073 can serve as a diagnostic predictor for childhood ALL, but only in girls and patients younger than or equal to 3.5 years old. More importantly, it can serve as a prognostic marker for high-risk classification and shorter survival time. Further validation studies can help extend the use of this prognostic predictor in clinical practice., (Copyright © 2023 International Institute of Anticancer Research (Dr. George J.

Background/aim: Acute lymphoblastic leukemia (ALL) is frequent among children. Few studies have researched the relationship between maternally expressed gene 3 (MEG3) and cancer risk. We hypothesized long non-coding RNA MEG3 polymorphisms might influence the risk of childhood ALL., Materials and Methods: In a total of 266 patients with childhood ALL and 266 healthy controls, genotypes of MEG3 rs7158663, rs3087918, rs11160608 and rs4081134 single nucleotide polymorphisms were investigated for their associations with childhood ALL., Results: MEG3 rs7158663 AG and AA genotypes were significantly associated with ALL [odds ratio=1.61 (95% confidence interval=1.12-2.31) and 2.21 (1.16-4.22), respectively]. The A allele also exhibited a statistical association with higher risk of ALL (p=0.0015). There was no positive association as for rs3087918, rs11160608 or rs4081134. Interestingly, a significant interaction between MEG3 rs7158663 and age (≥3.5 years) and gender (male) was found., Conclusion: MEG3 rs7158663 AG/AA genotypes were associated with higher susceptibility to childhood ALL. These novel findings should be validated in larger populations and different ethnicities., (Copyright © 2022, International Institute of Anticancer Research (Dr. George J.

In Taiwan, The increase in life expectancy in Taiwan has increased the incidents of age-related problems among patients with mental illness. Therefore, the needs related to long-term care in mental health are significantly important. These needs include: (1) reducing stigmatization; (2) reducing the physical and economic burden of caregivers; (3) constructing a comprehensive, long-term care service system; and (4) developing assessment tools suitable to the long-term care of patients with mental illness. Moreover, six dilemmas in meeting long-term care needs were identified. These dilemmas include: (1) lack of a model of continuous care and of a platform for integrating hospital and community resources; (2) poor / inadequate service quality provided by certain community rehabilitation institutions; (3) the needs of patient/family centered care; (4) the persistence of stigma and misunderstanding; (5) the heavy burdens borne by family members providing long-term care; and (6) the disconnect between subsequent needs and the disability assessment system. Policy suggestions provided in this article include: (1) establish an inclusive platform for mental health long-term care information and resource integration; (2) construct long-term care centers for patients with mental health conditions; (3) train adequate manpower to provide long-term care services to these patients; and (4) promote community inclusiveness for these patients. In order to enter the era of long-term mental health care, government policy should target long-term care programs to meet the needs of patients with mental health conditions. These programs should include seamlessly integrating services into the long-term mental health care system and the care resources of community mental health, developing suitable assessment tools, establishing a multidisciplinary team of long-term care professionals to provide mental health care.
