Efficacy of psychological treatments for patients with schizophrenia and relevant negative symptoms: A meta-analysis
Authors: Riehle Marcel , Böhl Mara Cristine , Pillny Matthias , Lincoln Tania Marie
Published: September 2020

Background

Recent meta-analyses on the efficacy of psychological treatments for the negative symptoms of schizophrenia included mostly trials that had not specifically targeted negative symptoms. To gauge the efficacy of such treatments in the target patient population – namely people with schizophrenia who experience negative symptoms – we conducted a meta-analysis of controlled trials that had established an inclusion criterion for relevant negative symptom severity.

Method

We conducted a systematic literature search and calculated random-effects meta-analyses for controlled post-treatment effects and for pre-post changes within treatment arms. Separate analyses were conducted for different therapeutic approaches. Our primary outcome was reduction in negative symptoms; secondary outcomes were amotivation, reduced expression, and functioning.

Results

Twelve studies matched our inclusion criteria, testing Cognitive Behavioral Therapy (CBT) vs. treatment-as-usual (k = 6), Cognitive Remediation (CR) vs. treatment-as-usual (k = 2), CBT vs. CR (k = 2), and Body-oriented Psychotherapy (BPT) vs. supportive group counseling and vs. Pilates (k = 1 each). Accordingly, meta-analyses were performed for CBT vs. treatment-as-usual, CR vs. treatment-as-usual, and CBT vs. CR. CBT and CR both outperformed treatment-as-usual in reducing negative symptoms (CBT: Hedges’ g = -0.46; CR: g = -0.59). There was no difference between CBT and CR (g = 0.12). Significant pre-post changes were found for CBT, CR, and to a lesser extent for treatment-as-usual, but not for BPT.

Conclusion

Although effects for some approaches are promising, more high-quality trials testing psychological treatments for negative symptoms in their target population are needed to place treatment recommendations on a sufficiently firm foundation.
The 12-month course of ICD-11 adjustment disorder in the context of involuntary job loss
Authors: Lorenz Louisa , Maercker Andreas , Bachem Rahel
Published: September 2020

Background

After its redefinition in ICD-11, adjustment disorder (AjD) comprises two core symptom clusters of preoccupations and failure to adapt to the stressor. Only a few studies investigate the course of AjD over time and the definition of six months until the remission of the disorder is based on little to no empirical evidence. The aim of the present study was to investigate the course of AjD symptoms and symptom clusters over time and to longitudinally evaluate predictors of AjD symptom severity.

Method

A selective sample of the Zurich Adjustment Disorder Study, N = 105 individuals who experienced involuntary job loss and reported either high or low symptom severity at first assessment (t1), were assessed M = 3.4 (SD = 2.1) months after the last day at work, and followed up six (t2) and twelve months (t3) later. They completed a fully structured diagnostic interview for AjD and self-report questionnaires.

Results

The prevalence of AjD was 21.9% at t1, 6.7% at t2, and dropped to 2.9% at t3. All individual symptoms and symptom clusters showed declines in prevalence rates across the three assessments. A hierarchical regression analysis of symptoms at t3 revealed that more symptoms at the first assessment (β = 0.32, p = .002) and the number of new life events between the first assessment and t3 (β = 0.29, p = .004) significantly predicted the number of AjD symptoms at t3.

Conclusion

Although prevalence rates of AjD declined over time, a significant proportion of individuals still experienced AjD symptoms after six months. Future research should focus on the specific mechanisms underlying the course of AjD.

Authors: Probst Thomas , Mühlberger Andreas , Kühner Johannes , Eifert Georg H. , Pieh Christoph , Hackbarth Timo , Mander Johannes
Published: September 2020

Background

Assessing in-session processes is important in psychotherapy research. The aim of the present study was to create and evaluate a short questionnaire capturing the patients’ view of the in-session realization of the six core components of Acceptance and Commitment Therapy (ACT).

Method

In two studies, psychotherapy patients receiving ACT (Study 1: n = 87) or Cognitive-Behavioral Therapy (CBT) (Study 2, Sample 1: n = 115; Sample 2: n = 156) completed the ACT session questionnaire (ACT-SQ). Therapists were n = 9 ACT therapists (Study 1) and n = 77 CBT trainee therapists (Study 2).

Results

Factor structure: Exploratory factor analyses suggested a one-factor solution for the ACT-SQ. Reliability: Cronbach’s alpha of the ACT-SQ was good (Study 1: α = .81; Study 2, Sample 1: α = .84; Sample 2: α = .88). Convergent validity: The ACT-SQ was positively correlated with validated psychotherapeutic change mechanisms (p < .05). Criterion validity: Higher ACT-SQ scores were associated with better treatment outcomes (p < .05).

Conclusion

The study provides preliminary evidence for the reliability and validity of the ACT-SQ to assess the in-session realization of the six core components of ACT in the patients’ view. Further validation studies and ACT-SQ versions for therapists and observers are necessary.
Internet Service Providers’ Pricing Strategies for Loyal Customers
Authors: Tuan Trinh Anh
Published: September 2020

In this paper, we investigate the impacts of user behaviour – user loyalty in particular – on pricing strategies of Internet Service Providers (ISPs) for a profitable yet sustainable Internet access marketplace. First, we propose a realistic user loyalty model, the price difference dependent loyalty model, which is based on empirical evidences from ISPs in different countries in the world. Next, we apply the loyalty model in gametheoretical analyses where optimal Internet access pricing strategies are expressed. Finally, we present the impacts of user loyalty on the prices and profits of ISPs in different scenarios based on simulation results

Published: September 2020

Yeasts, commonly present on the surface of fruits, are of industrial interest for the production of enzymes, flavorings, and bioactive compounds, and have many other scientific uses. The Amazonian rainforest may be a good source of new species or strains of yeasts, but their presence on Amazonian fruits is unknown. The aim of this study was to identify and characterize yeasts isolated from Amazonian native fruits using molecular and phenotypic methods. In total, 81 yeast isolates were obtained from 10 fruits species. Rep-PCR showed 29 strain profiles. Using a combination of restriction-fragment length polymorphism (RFLP) of the 5.8S-ITS region and D1/D2 sequencing of the 26S rRNA gene, 16 species were identified belonging to genera Candida, Debaryomyces, Hanseniaspora, Kodamaea, Martiniozyma, and Meyerozyma. The most dominant species were Candida tropicalis, Debaryomyces hansenii, Hanseniaspora opuntiae, and Hanseniaspora thailandica. H. opuntiae and H. thailandica showed the highest number of the strain profiles. Phenotypic profiles were variable between species, and even among strains. Screening for hydrolases showed lipolytic activity in only one isolate, while proteolytic, cellulolytic and amylolytic capabilities were not detected. Yeast presence among fruits varied, with cidra (Citrus medica) and ungurahui (Oenocarpus bataua) having the highest number of species associated. This investigation broadens the understanding and possible biotechnological uses of yeast strains obtained from Amazonian native fruits.

Authors: FAQE MAHMOOD SHLER AKRAM , BAKR HAWRI MUSTAFA
Published: September 2020

The present study was conducted to evaluate the infection rates of Entamoeba histolytica, Entamoeba dispar, and Entamoeba moshkovskii among asymptomatic individuals in Erbil City, northern Iraq. The research intent was to discover whether pathogenic or nonpathogenic species cause a high rate of symptomless Entamoeba infections. Stool samples were microscopically examined, and the 18S-rRNA gene was targeted utilizing the nested PCR technique in the positive specimens. Initial results based on morphological features showed that the Entamoeba prevalence rate was 7.4%. Significantly higher rates of infections were seen in females than in males and in low-income people than in moderate-income people. The incidence rates among the asymptomatic individuals, as determined by molecular analysis, were as follows: E. histolytica – 6%, E. dispar – 4.3%, and E. moshkovskii – 0.3%. Of all the Entamoeba positive samples, a single infection with E. histolytica was identified in 41.4% samples; the single infection with E. dispar in 18.6% samples, 35.7% samples had mixed infections with two Entamoeba species, and 4.3% had mixed infections with three species. The current study concluded that 7.4% of healthy people, who live in the endemic area under investigation, carry Entamoeba species asymptomatically. Additionally, the majority of asymptomatic Entamoeba infections were caused by the pathogenic E. histolytica (81.4%) compared to E. dispar (58.6%), and E. moshkovskii with the lowest rate of infection. Single and co-infections with E. histolytica and E. dispar were noted. E. moshkovskii, which was identified for the first time in the region, was only seen in mixed infections.

Dengue fever is a major public health problem in Saudi Arabia. Unfortunately, preventive strategies are still deficient. It can progress to severe and lethal forms, and available knowledge does not allow early prediction of which cases of dengue fever (DF) will progress to dengue hemorrhagic fever (DHF). The aim of this study was to evaluate the host and viral factors that could play a role in the progression of severe dengue cases in the frame of the revised 2009 WHO classification. Data were compiled from the Jeddah Dengue Fever Operation Room (DFOR) in the Maden Al-Fahd primary healthcare center in Jeddah. An unmatched case-control study was conducted on 123 severe cases, and 245 controls (non-severe cases) diagnosed during 2014–2016. Risk factors for severe dengue fever were secondary infection (p = 0.02), and co-morbidities, particularly diabetes and hypertension (p < 0.001). Age, gender, nationality, socioeconomic status, viral serotype, and access to health care were not significantly associated with severe disease. The main risk factors for severe dengue fever were secondary infection, and co-morbidities (hypertension and diabetes). We recommend disseminating these data to stakeholders to improve dengue control interventions in periods with anticipated high incidence.

The capacity of four bacterial strains isolated from productive soil potato fields to solubilize tricalcium phosphate on Pikovskaya agar or in a liquid medium was evaluated. A bacterial strain was selected to evaluate in vitro capacity of plant-growth promotion on Solanum tuberosum L. culture. Bacterial strain A3 showed the highest value of phosphate solubilization, reaching a 20 mm-diameter halo and a concentration of 350 mg/l on agar and in a liquid medium, respectively. Bacterial strain A3 was identified by 16S rDNA analysis as Bacillus pumilus with 98% identity; therefore, it is the first report for Bacillus pumilus as phosphate solubilizer. Plant-growth promotion assayed by in vitro culture of potato microplants showed that the addition of bacterial strain A3 increased root and stems length after 28 days. It significantly increased stem length by 79.3%, and duplicated the fresh weight of control microplants. In this paper, results reported regarding phosphorus solubilization and growth promotion under in vitro conditions represent a step forward in the use of innocuous bacterial strain biofertilizer on potato field cultures.

The Timing of Umbilical Cord Clamping and Its Effect on Maternal and Neonatal Outcomes in a Private Hospital, Bangkok, Thailand
Authors: Janngiab Chatchada , Suthutvoravut Somsak
Published: September 2020

Background: The timing of umbilical cord clamping after birth is important to neonatal health, and immediate umbilical cord clamping may have negative effects on the newborn’s health. In 2017, the American College of Obstetricians and Gynecologists recommended a delay in umbilical cord clamping in vigorous term and preterm infants for at least 30 to 60 seconds after birth.

Objective: To study the timing of umbilical cord clamping after birth and its effects on mothers and newborns in a private hospital.

Methods: The descriptive prospective observational study was conducted in the labor ward of a private hospital in Bangkok, Thailand. A total of 159 pregnant women were purposively recruited during August 1, 2017, to September 30, 2017. The time after the birth of the umbilical cord clamping was observed and recorded without the knowledge of the obstetricians. Data were analyzed using descriptive statistics.

Results: The mean time of the umbilical cord clamping was 6.20 ± 1.42 seconds (range, 2 - 10 seconds) after the birth which was shorter than the recommendation. No significant association was found between variables and the timing of the umbilical cord clamping. No significant adverse neonatal condition was found.

Conclusions: This study found that time of umbilical cord clamping in a private hospital was shorter than the recommendation and no known side effect to newborns.

The delivery of cancer care has never changed as rapidly and dramatically as we have seen with the coronavirus disease 2019 (COVID‐19) pandemic. During the early phase of the pandemic, recommendations for the management of oncology patients issued by various professional societies and government agencies did not recognize the significant regional differences in the impact of the pandemic. California initially experienced lower than expected numbers of cases, and the health care system did not experience the same degree of the burden that had been the case in other parts of the country. In light of promising trends in COVID‐19 infections and mortality in California, by late April 2020, discussions were initiated for a phased recovery of full‐scale cancer services. However, by July 2020, a surge of cases was reported across the nation, including in California. In this review, the authors share the response and recovery planning experience of the University of California (UC) Cancer Consortium in an effort to provide guidance to oncology practices. The UC Cancer Consortium was established in 2017 to bring together 5 UC Comprehensive Cancer Centers: UC Davis Comprehensive Cancer Center, UC Los Angeles Jonsson Comprehensive Cancer Center, UC Irvine Chao Family Comprehensive Cancer Center, UC San Diego Moores Cancer Center, and the UC San Francisco Helen Diller Family Comprehensive Cancer Center. The interventions implemented in each of these cancer centers are highlighted, with a focus on opportunities for a redesign in care delivery models. The authors propose that their experiences gained during this pandemic will enhance pre‐pandemic cancer care delivery.

Introdução: A COVID-19 é uma infecção causada pelo ví­rus SARS-CoV-2, que se originou na cidade de Wuhan (China) e se propagou rapidamente para outros paí­ses e continentes até que a Organização Mundial da Saúde (OMS) declarasse situação de pandemia. Dentre as condições graves decorrentes da patologia, observou-se que determinados pacientes apresentaram sintomatologias neurológicas sistêmicas, como acidente vascular encefálico (AVE). Objetivo: O objetivo do presente trabalho é propor uma discussão acerca dos conhecimentos atuais sobre a fisiopatologia do AVE em adultos jovens com COVID-19. Métodos: Fora realizada uma busca nas principais bases de dados: LILACS, BIREME, PuBMED nos idiomas português e inglês, de artigos compreendidos no ano vigente. A escolha ocorrera de forma aleatória, obviamente, seguindo uma linha de raciocí­nio dos autores envolvidos. As palavras-chave pesquisadas foram: COVID-19, Acidente Vascular Encefálico, Fisiopatologia, Coagulopatia. Discussão: Conjectura-se inúmeras possiblidades que explicariam a ligação do ví­rus í  doença cerebrovascular. É considerado que o SARS-CoV-2 instiga um processo inflamatório na parede arterial e isso seja responsável pelo AVE. Embora a correlação entre essas duas condições clí­nicas seja notória, ainda não existem estudos que determinem claramente o mecanismo fisiopatológico implicado no processo. Conclusão: Manifestações neurológicas na COVID-19 são relatadas, incluindo o acidente vascular encefálico. O estado de hipercoagulabilidade gerado pela tempestade de citocinas parece estar relacionado ao mecanismo fisiopatológico desta condição. Ainda assim, não existem evidências claras quanto a isso e estudos são necessários a fim de elucidar sua fisiopatogenia.Palavras-chave: infecção por coronaví­rus, acidente vascular encefálico, fisiopatologia, coagulopatia.

Introduction: The COVID-19 pandemic is a major Public Health problem today. Social isolation is the main measure established so far to delay the spread of this pathology. However, the loneliness resulting from confinement can be particularly problematic in senescence. This article aimed to produce and update reflections about the impact of social isolation on the mental health of the elderly during the COVID-19 pandemic. Methodology: A search was carried out in the main data sources: Lilacs, Bireme and Pubmed, in Portuguese and English. Articles that address inclusion requirements were selected and exclude those that do not. It was also decided to perform a reverse search, in order to expand and diversify the results. Results: By crossing the keywords in the database, a total of 475 publications were found. Joining selected articles in the database and in the reverse search, the sample was composed of 21 articles in all. Conclusion: Social isolation negatively affects the mental health of the elderly. Thus, health professionals must be prepared to face an epidemic of emotional disorders arising from the confinement of this population.Keywords: elderly, mental health, pandemic, COVID-19, social isolation.

Authors: Ahmed Md Sagir , Datta Sujan Kumar , Zhilik Ayesha Akhter
Published: September 2020

This study represents the comprehensive molecular identification of freshwater fishes of Bangladesh based on a fragment of the cytochrome c oxidase subunit I (COI) gene in the mitochondrial genome. A total of 315 mitochondrial COI barcode sequences were obtained from 153 species,114 genera, 49 families and 16 orders of fishes. The mean length of the sequences was 652 base pairs. For all the samples, %G was significantly lower compared to the other nucleotides and %GC was lower compared to %AT (p-value ˂ 0.05). Also, a significantly lower %GC content was observed in second and third codon position compared to the first one in all the samples (1st>2nd>3rd, p-value˂ 0.05). The average K2P distances within species, genera, families and orders were 0.38%, 7.02%, 12.75% and 18.68%, respectively. The mean interspecific distance was 18-fold higher than the mean intraspecific distance. The K2P neighbor-joining (NJ) trees based on the sequences generally clustered species according to their taxonomic position. A total of 12 species were newly recorded in Bangladesh. High efficiency in species identification were demonstrated in the present study by DNA barcoding, and concluded that COI sequencing can be used as an authentic identification marker for freshwater fish species.

Published: September 2020

The study was conducted to identify the protozoan parasites and to determine their occurrence and diversity in climbing perch, Anabas testudineus (Bloch, 1972). The sample fish species were collected from mid-October, 2018 to end of the December 2018 from freshwater bodies of Mymensingh, Kishoregonj, Faridpur and Jashore districts. Three species of myxozoa (Henneguya mystusia, Henneguya qadrii and Henneguya acerinae) and 4species of ciliophora (Trichodina acuta, Trichodina spp., Epistylis lwoffi and Amphileptus disciformis) were identified in A. testudineus. Approximately 76.19% of total fish species were infected by at least one of the parasites with average load of 71.38±32.26 per infected host. Myxozoans (97.55%) were clearly dominant group than chiliophorans (2.45%). The highest prevalence of parasitic infection was observed in the fishes of Mymensingh (100%) and lowest in Jashore (40%).The association of parasitic infection of H. mystusia (p=0.018), H. qadrii (p= 0.00044), H. acerinae (p=0.003), Trichodina acuta (p= 0.052)and A. disciformis (p= 0.023) with study area was statistically significant. Protozoan parasites were most abundant in gills of the hosts. Shannon Diversity Index indicated that hosts were not infested by more parasites and the parasite community was poorly diverged in all study sites but Simpson’s Diversity Index showed that, parasites community was moderately diverged in host fish of Mymensingh area and in rest of areas they were poorly diverged.
