The performance of loop-mediated isothermal amplification (LAMP) for detection of Schistosoma mansoni DNA from stool and urine samples in comparison with Kato-Katz and real-time polymerase chain reaction (PCR) was studied. After obtaining informed consent, 50 children participated in the present study and agreed to submit stool and urine samples. Stool samples were examined by Kato-Katz. Both real-time PCR and LAMP techniques were applied on stool and urine samples. The overall prevalence of S. mansoni was 46% in stool and urine samples as detected by the employed techniques, and 90% of cases had light infection intensity. The highest percentage of infection was diagnosed by real-time PCR (44%), followed by Kato-Katz (42%) and LAMP in the stool (36%), while the lowest percentages of infection were diagnosed by real-time PCR and LAMP in urine samples (24% and 14%, respectively). Kato-Katz, real-time PCR and LAMP showed 100% specificity where the sensitivity was 91.3%, 95.7% and 78.3%, respectively, in stool samples. Real-time PCR and LAMP showed lower sensitivity in urine samples. The LAMP assay is a promising technique for S. mansoni diagnosis in endemic countries of moderate and high-intensity infection. Yet, it needs further optimization, particularly in urine samples.
In March 2020, New York City became the epicenter of the coronavirus disease 2019 (COVID-19) pandemic in the United States. Because healthcare facilities were overwhelmed with patients, the Jacob K. Javits Convention Center was transformed into the nation's largest alternate care site Javits New York Medical Station (hereafter termed Javits). Protecting healthcare workers (HCWs) during a global shortage of personal protective equipment (PPE) in a nontraditional healthcare setting posed unique challenges. We describe components of the HCW safety program implemented at Javits.
Javits, a large convention center transformed into a field hospital, with clinical staff from the US Public Health Service Commissioned Corps and the US Department of Defense.
Key strategies to ensure HCW safety included ensuring 1-way flow of traffic on and off the patient floor, developing a matrix detailing PPE required for each work activity and location, PPE extended use and reuse protocols, personnel training, and monitoring adherence to PPE donning/doffing protocols when entering or exiting the patient floor. Javits staff who reported COVID-19 symptoms were immediately isolated, monitored, and offered a severe acute respiratory coronavirus virus 2 (SARS-CoV-2) reverse-transcriptase polymerase chain reaction (RT-PCR) test.
A well-designed and implemented HCW safety plan can minimize the risk of SARS-CoV-2 infection for HCWs. The lessons learned from operating the nation's largest COVID-19 alternate care site can be adapted to other environments during public health emergencies.

Drawing upon data generated in a phenomenological study of the aging-out-place experience, this article presents a hermeneutic analysis of textual extracts addressing 10 Sri Lankan-born late-life immigrants' Buddhist beliefs and practices, and how these beliefs and practices contributed to coping with immigration stressors. Four shared experiences facilitated through religious engagement were revealed religious engagement as a source of purpose, making meaning of suffering and experiencing hope, non-attachment, and connecting to the past and the ethnoreligious community. Late-life immigrants drew on religious engagement to remain resolute amidst adversities, thus reinforcing the importance of culturally responsive milieus and services to support religion-focused coping. Findings are interpreted in relation to Pargament's (1997) theory of religious coping.This interpretative, qualitative study explored residents' and families' perspectives on advance care planning (ACP) in long-term care (LTC). Perspectives on when, how, and with whom ACP discussions should be introduced and barriers and solutions to improving ACP engagement were examined. Fifty-one residents and families participated in seven focus groups. The findings revealed that residents and families prioritized caring connections over professional rank when reflecting on staff involvement in ACP. The findings further revealed that the caring and compassionate environment considered to be a critical pre-condition for ACP engagement was more typically enacted at end of life when ACP was no longer an option. Our findings suggest that work practices and organizational structures within LTC play an important role in inhibiting ACP engagement.
There is increasing attention on the association of socioeconomic status and individual behaviors (SES/IB) with mental health. However, the impacts of SES/IB on mental disorders are still unclear. To provide evidence for establishing feasible strategies on disease screening and prevention, we implemented Mendelian randomization (MR) design to appraise causality between SES/IB and mental disorders.
We conducted a two-sample MR study to assess the causal effects of SES and IB (dietary habits, habitual physical activity, smoking behaviors, drinking behaviors, sleeping behaviors, leisure sedentary behaviors, risky behaviors, and reproductive behaviors) on three mental disorders, including bipolar disorder, major depressive disorder and schizophrenia. A series of filtering steps were taken to select eligible genetic instruments robustly associated with each of the traits. Inverse variance weighted was used for primary analysis, with alternative MR methods including MR-Egger, weighted median, and weighted mode estimate. Complementary methods were further used to detect pleiotropic bias.
After Bonferroni correction and rigorous quality control, we identified that SES (educational attainment), smoking behaviors (smoking initiation, number of cigarettes per day), risky behaviors (adventurousness, number of sexual partners, automobile speeding propensity) and reproductive behavior (age at first birth) were causally associated with at least one of the mental disorders.
MR study provides robust evidence that SES/IB play broad impacts on mental disorders.

Methamphetamine (METH) is classified as a Schedule II stimulant drug under the United Nations Convention on Psychotropic Substances of 1971. METH and other amphetamine analogues (AMPHs) are powerful addictive drugs. Treatments are needed to treat the symptoms of METH addiction, chronic METH use, and acute METH overdose. No effective treatment for METH abuse has been established because alterations of brain functions under the excessive intake of abused drug intake are largely irreversible due in part to brain damage that occurs in the course of chronic METH use.
Modulation of brain histamine neurotransmission is involved in several neuropsychiatric disorders, including substance use disorders. This review discusses the possible mechanisms underlying the therapeutic effects of histamine H
receptor antagonists on symptoms of methamphetamine abuse.
Treatment of mice with centrally acting histamine H
receptor antagonists increases hypothalamic histamine contents and reduces high-dose METH effects while potentiating lowdose effects via histamine H
receptors that bind released histamine. On the basis of experimental evidence, it is hypothesized that histamine H
receptors may be an effective target for the treatment METH use disorder or other adverse effects of chronic METH use.
Treatment of mice with centrally acting histamine H3 receptor antagonists increases hypothalamic histamine contents and reduces high-dose METH effects while potentiating lowdose effects via histamine H3 receptors that bind released histamine. On the basis of experimental evidence, it is hypothesized that histamine H3 receptors may be an effective target for the treatment METH use disorder or other adverse effects of chronic METH use.Oxytocin facilitates reproduction both by physiological and behavioral mechanisms. Oxytocinergic neurons emerging from the hypothalamus release oxytocin from the pituitary gland to the blood by axonal discharge to regulate reproductive organs. However, at the same time, oxytocin is secreted into neighboring areas of the hypothalamus from the dendrites of these neurons. Here, the peptide acts by autocrine and paracrine mechanisms to influence other neuroendocrine systems. buy I-191 Furthermore, oxytocinergic neurons project to many different locations in the brain, where they affect sensory processing, affective functions, and reward. Additional to its regulatory role, significant anti-inflammatory and restoring effects of oxytocin have been reported from many invivo and in-vitro studies. The pervasive property of the oxytocin system may enable it generally to dampen stress reactions both peripherally and centrally, and protect neurons and supportive cells from inadequate inflammation and malfunctioning. Animal experiments have documented the importance of preserving immune- and stem cell functions in the hypothalamus to impede age-related destructive processes of the body. Sexual reward has a profound stimulating impact on the oxytocinergic activity, and the present article therefore presents the hypothesis that frequent sexual activity and gratigying social experiance may postpone the onset of frailty and age-associated diseases by neural protection from the bursts of oxytocin. Furthermore, suggestions are given how the neuroplastic properties of oxytocin may be utilized to enhance sexual reward by learning processes in order to further reinforce the release of this peptide.Osteoporosis is becoming more prevalent following the entry of the aging era and, however, its treatment is still a headache problem. Traditional Chinese Medicine (TCM) has a long history in treating osteoporosis and is receiving increasing attention. Multiple formulas of TCM showed satisfactory effects in treating osteoporosis in both animal models and clinical patients. However, because TCM usually consists of multiple plant and/or animal products, it is difficult to clarify the mechanism of TCM according to the requirements of Western medicine about purity, efficacy, dosage, and safety. With increasing researchers have started to investigate the TCM using modern scientific tools such as bioinformatics and network pharmaceutics in osteoporosis and the addition of TCM in the latest version of International Statistical Classification of Diseases and Related Health Problems (ICD-11 version, 2019) by WHO, TCM is showing large potential in treating osteoporosis although there is still a long way. The review aimed to summarize recent advancements of TCM treating osteoporosis.
Curcumin has been isolated from the rhizomes of Curcuma longa. Over the years, it has shown outstanding therapeutic potential in various human disorders including cancers.
The curcumin effects on the signaling pathway of apoptosis in head and neck squamous cell carcinoma (HNSCC) cell line HN5 were studied in this study.
The cytotoxicity of curcumin on HN5 cells was assessed. In addition, HN5 cells were also treated with curcumin to evaluate its effect on the caspase-8, -9, Bcl-2, Bax, and Stat3 genes expression.
The results exhibited that viability of cells reduced following treatment of curcumin in a concentration-dependent manner. Curcumin treatment caused decreased expression of Bcl2, with simultaneous upregulation of the Bax/Bcl2 ratio. Curcumin led to an increase in the caspase-9 expression and no effect on caspase-8. Also, it caused to decrease in Stat3 expression. The induction of the mitochondria-dependent apoptosis pathway of curcumin happened by the modulation in the expression of Bcl2 and Bax genes, resulting in the caspase-9 activation, also curcumin causes the decreasing the expression of the Stat3 in HN-5 cells.
