Abstract. The objective of the present study was to determine the parenteral dosage of the trace mineral copper (Cu) which re-establishes serum and hepatic levels in hypocupperhemic animals without causing intoxication in the liver or residuals in milk. The experiment was carried out in two phases; in the first phase, 20 hypocupperhemic animals were used. Those were divided into 4 groups of 5 cows each: 3 groups which received 25, 50 and 100 mg of Cu respectively and 1 control group without supplementation, but with induced copraemia 5 days before and after the treatment. The milk of the cows treated with 100 mg Cu was examined for residuals of this element for one month. In the second phase, 25 animals were selected and divided into 5 groups of 5 cows each: 1 control group and 4 groups which received 25, 50, 100 and 200 mg of Cu respectively. The impact of this Cu dosages on liver reserves of this element, on hepatic enzymes (alanine-amine-transaminase, aspartate-amine-transferase, alkaline phosphatase and glutamate dehydrogenase) and on bilirubin was analyzed. The groups treated with 50 and 100 mg Cu showed increased levels in blood serum and hepatic tissues (P<0.05) in comparison to the control group and the one treated with 25 mg, obtaining the physiological level considered normal in cows during 60 days without an effect to the level of Cu in milk or to the liver’s enzymatic activity. We conclude that treatment with this dosage results in a restoration of the Cu concentration in blood serum and hepatic tissues without toxic effects or residuals.

Background: Hepatic encephalopathy (HE), a neuropsychiatric complication of decompensated cirrhosis, is associated with high mortality and high risk of recurrence. Rifaximin add-on to lactulose for 3 to 6 months is recommended for the prevention of recurrent episodes of HE after the second episode. However, whether the combination for more than 6 months is superior to lactulose alone in the maintenance of HE remission is less evident. Therefore, the aim of this study is to evaluate the one-year efficacy of rifaximin add-on to lactulose for the maintenance of HE remission in Taiwan. Methods: We conducted a real-world single-center retrospective cohort study to compare the long-term efficacy of rifaximin add-on to lactulose (group R + L) versus lactulose alone (group L, control group). Furthermore, the treatment efficacy before and after rifaximin add-on to lactulose was also analyzed. The primary endpoint of our study was time to first HE recurrence (Conn score ≥ 2). All patients were followed up every three months until death, and censored at one year if still alive. Results and Conclusions: 12 patients were enrolled in group R + L. Another 31 patients were stratified into group L. Sex, comorbidity, ammonia level, and ascites grade were matched while age, HE grade, and model for end-stage liver disease (MELD) score were adjusted in the multivariable logistic regression model. Compared with group L, significant improvement in the maintenance of HE remission and decreased episodes and days of HE-related hospitalizations were demonstrated in group R + L. The serum ammonia levels were significantly lower at the 3rd and 6th month in group 1. Concerning changes before and after rifaximin add-on in group R + L, mini-mental status examination (MMSE), episodes of hospitalization, and variceal bleeding also improved at 6 and 12 months. Days of hospitalization, serum ammonia levels also improved at 6th month. Except for concern over price, no patients discontinued rifaximin due to adverse events or complications. The above results provide evidence for the one-year use of rifaximin add-on to lactulose in reducing HE recurrence and HE-related hospitalization for patients with decompensated cirrhosis.

A number of studies suggest a link between musical training and both specific and general cognitive abilities, but despite some positive results, there is disagreement about which abilities are improved. This study aims to investigate the effects of a music education program both on a domain-specific competence (meta-musical awareness), and on general domain competences, that is, cognitive abilities (logical-mathematical) and symbolic-linguistic abilities (notational). Twenty 4- to 6-year-old children participated in the research, divided into two groups (experimental and control) and the measures were administered at two different times, before and after a 6-month music program (for the experimental group) and after a sports training program (for the control group). Children performed meta-musical awareness tasks, logical-mathematical tasks, and emergent-alphabetization tasks. Non-parametric statistics show that a music program significantly improves the development of notational skills and meta-musical awareness while not the development of logical-mathematical skills. These results show that a musical program increases children’s meta-musical awareness, and their ability to acquire the notational ability involved in the invented writing of words and numbers. On the contrary, it does not affect the development of logical skills. The results are discussed in terms of transfer of knowledge processes and of specific versus general domain effects of a musical program.

Abstract Background Procalcitonin (PCT) is a biomarker that shows good sensitivity and specificity in identifying septic patients. Methods This study investigated the diagnostic accuracy of PCT in a community hospital setting and how it compared to that of lactic acid. It explored the impact on patient care before and after PCT implementation regarding costs and length of stay. Two comparative groups were analyzed using an exploratory descriptive case–control study with data from a 19-month period after PCT implementation and a retrospective quasi-experimental study using a control group of emergency department patients diagnosed with sepsis using data before PCT implementation. Results Post-procalcitonin implementation samples included 165 cases and pre-procalcitonin implementation sample included 69 cases. From the 165 sepsis cases who had positive blood cultures, PCT had a sensitivity of 89.7%. In comparison, lactic acid's sensitivity at the current cutoff of 18.02 mg/dL (2.0 mmol/L) was 64.9%. There was a 32% decrease in median cost before and after PCT implementation, even with the length of stay remaining at 5 days in both time periods. Conclusions There was a significant decrease after the implementation of PCT in cost of hospitalization compared to costs before implementation. This cost is highly correlated with length of stay; neither the hospital nor the intensive care unit length of stay showed a difference with before and after implementation. There was a positive correlation between lactic acid and PCT values. PCT values had a higher predictive usefulness than the lactic acid values.

Stigma toward mental disorders is one of today's most pressing global issues. The Covid-19 pandemic has exacerbated the barriers to social inclusion faced by individuals with mental disorders. Concurrently, stigma reduction interventions, especially those aimed at university students, have been more difficult to implement given social distancing and campus closures. As a result, alternative delivery for programs contributing to stigma reduction is required, such as online implementation. This paper reports the results of a controlled study focused on an online multi-component program on reducing stigma toward mental illness that included project-based learning, clinical simulations with standardized patients and E-Contact with real patients. A total of 40 undergraduate students from the Universidad del Desarrollo in Santiago, Chile, participated in the study. They were randomly divided between an intervention and control group. The intervention group participated in the online multi-component program, while the control group participated in an online educational program on cardiovascular health. We assessed the impact of the program by using the validated Spanish-language versions of the Attribution Questionnaire AQ-27 and the Questionnaire on Student Attitudes toward Schizophrenia with both groups, before and after the intervention. In addition, an ad hoc Likert scale ranging from 0 to 5 was used with the intervention group in order to assess the learning strategies implemented. Following the intervention, the participants belonging to the intervention group displayed significantly lower levels of stereotypes, perception of dangerousness, and global score toward people with schizophrenia (p &lt; 0.001). In addition, participants presented lower levels of dangerousness-fear, avoidance, coercion, lack of solidarity, and global score (p &lt; 0.001). The control group displayed no statistically significant differences in the level of stigma before and after the evaluation, for all of the items assessed. Finally, the overall assessment of each of the components of the program was highly positive. In conclusion, the study shows that online programs can contribute to reducing stigma toward mental disorders. The program assessed in this study had a positive impact on all the dimensions of stigma and all of the components of the program itself were positively evaluated by the participants.

Abstract Background Infection with measles virus (MeV) causes immunosuppression and increased susceptibility to other infectious diseases. Only few studies reported a duration of immunosuppression, with varying results. We investigated the effect of immunosuppression on the incidence of hospital admissions for infectious diseases in Vietnamese children. Methods We used retrospective data (2005 to 2015; N = 4419) from the two pediatric hospitals in Ho Chi Minh City, Vietnam. We compared the age-specific incidence of hospital admission for infectious diseases before and after hospitalization for measles. We fitted a Poisson regression model that included gender, current age, and time since measles to obtain a multiplicative effect measure. Estimates were transformed to the additive scale. Results We observed two phases in the incidence of hospital admission after measles. The first phase started with a fourfold increased rate of admissions during the first month after measles, dropping to a level quite comparable to children of the same age before measles. In the second phase, lasting until at least 6 years after measles, the admission rate decreased further, with values up to 20 times lower than in children of the same age before measles. However, on the additive scale the effect size in the second phase was much smaller than in the first phase. Conclusion The first phase highlights the public health benefits of measles vaccination by preventing measles and immune amnesia. The beneficial second phase is interesting, but its strength strongly depends on the scale. It suggests a complicated interaction between MeV infection and the host immunity.

The impact of natural disasters on individuals is substantial. Among the affected population in any disaster, children are identified as the most vulnerable group along with women, aged and disabled people. An estimated 77 million children under 15, on average, had their lives severely disrupted by a natural disaster or an armed conflict, each year, between 1991 and 2000 (Plan UK, 2003). Children are most affected since they loose the familiar environment, loss of parents, witness death of their loved ones, fear of reoccurrence of the disaster event. The impact of disaster on children of different age group is multiple times greater than that of the adults. This leads to various psychological problems in children (Dave et al., 2003). Disaster preparedness, through care givers, is one among the ways to reduce the distress of individuals followed by any disaster because it reduces the vulnerability factor that minimizes the impact of any disaster on the individual. A disaster preparedness program with special reference to psychosocial aspects was developed and implemented among the school children through teachers in Kanniyakumari District, Tamil Nadu, India, one of the severely affected areas in Tsunami. The current attempt was to standardize a disaster preparedness module focusing on preparing children to deal with their psychosocial issues before and after disaster in an effective manner. The outcome of disaster preparedness input through teachers and its reach out to the students was determined through an experimental research. The results reveal that the teachers and students from the experimental group gained significantly more knowledge on psychosocial disaster preparedness after implementation of the program in comparison to control group where the program was not implemented. The implications of the study points out the need to integrate psychosocial component of disaster preparedness in to the broader Community Based Disaster Preparedness (CBDP) programs.

Abstract BackgroundAlcohol use disorder (AUD) is a common psychiatric comorbidity in schizophrenia, associated with poor clinical outcomes and medication noncompliance. Most previous studies on the effect of alcohol use in patients with schizophrenia had limitations of small sample size and a cross-sectional design. Therefore, this study aimed to use a nationwide population database to investigate the impact of AUD on clinical outcomes of schizophrenia.MethodsData from the Health Insurance Review Agency database in South Korea from January 1, 2007 to December 31, 2016 was used. Among 64,442 patients with incident schizophrenia, 1,598 with comorbid AUD were selected based on the diagnostic code F10. We performed between- and within-group analyses to compare the rates of psychiatric admissions and emergency room (ER) visits and medication possession ratio (MPR) with control patients having schizophrenia matched for the onset age, sex, and observation period.ResultsThe rates of psychiatric admissions and ER visits decreased after the diagnosis of AUD in both groups; however, the decrease was significantly greater in patients with comorbid AUD compared to the control group. While the case group showed an increase in MPR after the diagnosis of AUD, MPR decreased in the control patients. The rates of psychiatric admissions, ER visits and MPR were worse in the schizophrenia group with comorbid AUD both before and after the diagnosis of AUD.ConclusionsClinical outcomes were worse in the comorbid AUD group than in the control group before and after the diagnosis of AUD. Considering that patients with schizophrenia with comorbid AUD had poorer clinical outcomes even before the diagnosis of AUD, schizophrenia with comorbid AUD could be a distinct subtype of schizophrenia.

Smoking and alcohol consumption is a growing trend among young people worldwide. The purpose of this study was to provide students with a comparative analysis of adherence to harmful habits (smoking and alcohol) on the one hand and the frequency of sports and academic performance on the other, taking into account gender differences. The research was conducted in 2019-2020 in 5 cities of Russia; the sample included 1500 people aged 18.4 ± 1.1 years, divided into three equal groups. The control (first) group had students who are not engaged in sports, and the second group comprised students practicing sports but not professionally. The third group was made up of student-athletes. All participants were surveyed to determine the frequency of adherence to harmful habits. In the control group, boys smoked 50% more often than girls (p ≤ 0.05), while in the third group, smoking among boys was registered 70 times less often (p ≤ 0.001). Alcohol consumption in controls was 0.5 times more likely among boys (p ≤ 0.05). Harmful habits affect young people's free time and reduce their academic performance and ability to practice sports.
