First Clinical Nutrition Outpatient Consultation: A Review of Basic Principles in Nutritional Care of Adults with Hematologic Disease.

Methods: A bibliographic survey was carried out between 2020 and 2022 using two databases: PubMed/MEDLINE and Scientific Electronic Library Online (SciELO) and the information source Academic Google, irrespective of language or geography. Results: In the first nutrition consultation (FNC), there should be an investigative direction focused on nutritional interventions in the short, medium, and long term. The record in the patient's medical record is relevant for carrying out the consultation, according to the recommendations of the normative councils of medicine and nutrition. The main steps to be followed are the investigation of the presence of food allergies and intolerances; the drugs/nutritional supplements in use; changes in the digestive tract; the presence or absence of picamalacia; and socioeconomic and lifestyle data. In addition, it is necessary to carry out laboratory evaluations, semiological assessment, anthropometric assessment, and assessment of food consumption. In the end, the nutritional approach should be composed of calculation of energy and macronutrient and micronutrient needs, intervention in nutritional status deviations, nutritional guidelines, and nutritional therapeutic planning of return, focusing on adherence to treatment. Conclusion: The first nutrition consultation may represent investigative steps that help the clinical nutritionist in the management, allowing a longitudinal and specific nutritional therapeutic planning for patients assisted in large reference centers for hematological disease.

Co-Channel Compatibility Analysis of IMT Networks and Digital Terrestrial Television Broadcasting in the Frequency Range 470-694 MHz Based on Monte Carlo Simulation.

According to Resolution 235 adopted during the World Radiocommunication Conference 2015 (WRC-15) and the preliminary agenda item 1.5 of WRC-2023, the International Telecommunication Union Radiocommunication Sector (ITU-R) has been entrusted to carry out sharing and compatibility studies between broadcasting and mobile services in the frequency range 470-694 MHz in Region 1. This study specifically focuses on evaluating electromagnetic compatibility in potential co-channel sharing scenarios between Digital Terrestrial Television Broadcasting (DTTB) and International Mobile Telecommunications (IMT) systems within the 470-694 MHz frequency band that may arise in the foreseeable future. To assess the conditions for coexistence, a Monte Carlo simulation method implemented through the SEAMCAT software version 5.4.2 is employed, examining six potential interference scenarios. The simulation results yield the minimum coordination distance required between IMT and DTTB services in the 470-694 MHz band based on the protection criteria to ensure harmonious coexistence while maintaining satisfactory performance. Furthermore, the study investigates the impact of various factors such as transmitter power, antenna heights, coverage radius, antenna discrimination, and antenna tilt angle on the separation distances. The focus lies primarily on critical interference scenarios across neighboring countries' borders. The simulation outcomes confirm that sharing the same frequency band between IMT and DTTB networks would result in significant mutual interference. Nevertheless, carefully analyzing diverse parameters and assumptions helped provide recommendations to reduce the required separation distances. These findings are valuable for broadcasters, mobile operators, and regulators in establishing the technical coexistence conditions for DTTB and IMT in the new band.

Propolis: Its Role and Efficacy in Human Health and Diseases.

With technological advancements in the medicinal and pharmaceutical industries, numerous research studies have focused on the propolis produced by stingless bees (Meliponini tribe) and Apis mellifera honeybees as alternative complementary medicines for the potential treatment of various acute and chronic diseases. Propolis can be found in tropical and subtropical forests throughout the world. The composition of phytochemical constituents in propolis varies depending on the bee species, geographical location, botanical source, and environmental conditions. Typically, propolis contains lipid, beeswax, essential oils, pollen, and organic components. The latter include flavonoids, phenolic compounds, polyphenols, terpenes, terpenoids, coumarins, steroids, amino acids, and aromatic acids. The biologically active constituents of propolis, which include countless organic compounds such as artepillin C, caffeic acid, caffeic acid phenethyl ester, apigenin, chrysin, galangin, kaempferol, luteolin, genistein, naringin, pinocembrin, coumaric acid, and quercetin, have a broad spectrum of biological and therapeutic properties such as antidiabetic, anti-inflammatory, antioxidant, anticancer, rheumatoid arthritis, chronic obstruct pulmonary disorders, cardiovascular diseases, respiratory tract-related diseases, gastrointestinal disorders, as well as neuroprotective, immunomodulatory, and immuno-inflammatory agents. Therefore, this review aims to provide a summary of recent studies on the role of propolis, its constituents, its biologically active compounds, and their efficacy in the medicinal and pharmaceutical treatment of chronic diseases.

The evolutionary and transmission characteristic of HIV-1 CRF07_BC in Nanjing, Jiangsu.

To understand the epidemiology, evolutionary and transmission characteristics of HIV-1 CRF07_BC in Nanjing, China. One hundred and fifty-nine patients with HIV-1 CRF07_BC were recruited. DNA sequencing, phylogenetic analysis, and molecular transmission cluster analysis were conducted to determine the molecular epidemiology and evolutionary characteristics. Of these HIV-1-infected patients, 95.6% were male, and men who sex with men (76.7%) were the main transmission route. Only 34.0% of these cases were born in Nanjing, and most of them (64.8%) reported having multiple sex partners in the last 6 months. The maximum likelihood phylogenetic analyses of HIV-1 CRF07_BC revealed two lineages. Overall, 67.3% of Nanjing sequences were connected to at least one other individual distributed in 11 clusters, and the average degree was 21.2 with range (1-178). The clustered patients were more likely to be male. The time to a most recent common ancestor for the early HIV-1 CRF07_BC circulating in Nanjing was estimated to be 1998.71[1997.36-2001.07]. The mean estimated evolutionary rate for the epidemic cluster was slightly lower at 2.38[2.12-2.65] × 10-3 per site per year with the relaxed exponential clock model. HIV-1 CRF07_BC was transmitted into Nanjing more than 20 years ago from Yunnan and has become one of the most predominant subtypes with a higher evolutionary rate than before.

Treatment outcomes of patients with tuberculosis in war affected region of Khyber Pakhtunkhwa, Pakistan.

BACKGROUND: Globally, tuberculosis (TB) remains the leading cause of death from a single infectious disease. TB treatment outcome is an important indicator for the effectiveness of a national TB control program. This study aimed to assess treatment outcomes of TB patients and its determinants in Batkhela, Khyber Pakhtunkhwa, Pakistan. METHODS: A retrospective cohort study was designed using all TB patients who were enrolled at District Head Quarter (DHQ) Hospital Batkhela, Pakistan, from January 2011 to December 2014. A binary logistic regression models were used to identify factors associated with successful TB treatment outcomes defined as the sum of cure and completed treatment. RESULTS: A total of 515 TB patients were registered, of which 237 (46%) were males and 278 (53.98%) females. Of all patients, 234 (45.44%) were cured and 210 (40.77%) completed treatment. The overall treatment success rate was 444 (86.21%). Age 0-20 years (adjusted odds ratio, AOR = 3.47; 95% confidence interval, CI) = 1.54-7.81; P = 0.003), smear-positive pulmonary TB (AOR) = 3.58; 95% CI = 1.89-6.78; P = < 0.001), treatment category (AOR = 4.71; 95% CI = 1.17-18.97; P = 0.029), and year of enrollment 2012 (AOR = 6.26; 95% CI = 2.52-15.59; P = < 0.001) were significantly associated with successful treatment outcome. CONCLUSIONS: The overall treatment success rate is satisfactory but still need to be improved to achieve the international targeted treatment outcome. Type of TB, age, treatment category, and year of enrollment were significantly associated with successful treatment outcomes.

Identification of culturable petroleum-degrading bacteria and fungi from petroleum-contaminated sites in Brunei Darussalam.

Microbes that can be cultured and degrade petroleum are of particular interest for biotechnology such as bioremediation. This study aims to isolate and identify culturable petroleum-degrading bacteria and fungi from Brunei Darussalam, which has not previously been explored. A total of eight bacterial and nine fungal isolates that could degrade petroleum were obtained from petroleum-contaminated water or soil samples. DNA barcoding using 16S rRNA gene sequence identified five different bacterial genera which were Bacillus, Enterobacter, Micrococcus, Pseudoaltermonas and Pseudomonas. DNA barcoding using rRNA-ITS gene sequence identified nine different fungal taxa which were Aspergillus, Cladosporium, Exophiala, Flavodon, Hypocreales, Nectriaceae, Penicillium, Peniophora and Trichoderma. Biolog provided additional support to the identification of some isolates. This study is the first to report these unique microbes from Brunei Darussalam, which are of ecological and biotechnological value.

The nationwide distribution and trends of hepatitis C virus genotypes in mainland China.

Comprehensive data on hepatitis C virus (HCV) genotypes distribution is critical for treatment regimen selection, vaccine design, and drug development. This study aimed to understand the dynamic distribution of HCV genotypes in Mainland China. Three hundred sixty-two studies published from January 1993 to December 2017 involving 64 891 samples (5133 injecting drug users, 2748 volunteer blood donors, 1509 former paid plasma donors, 160 sexually encounters, and 1992 human immunodeficiency virus (HIV)/HCV coinfection patients) were eligible for the quantitative synthesis estimation. Pooled proportion of HCV genotypes (and 95% confidence intervals [CIs]) was estimated through the Freeman-Tukey double arcsine transformation by period, region, and risk group. A sharp decline of the subtype 1b was observed in all regions except in northwestern and central regions. The genotypes 3 and 6 showed an obvious increase in southern and southwestern regions and have already spread nationwide. After 2010, subtype 1b was the most dominant variant in all regions and risk groups, accounting for 54.0% (95% CI, 51.9-56.1) of all national infections. Subtype 2a was the second most prevalent strain in all regions except in the south and southwest, with 15.4% (95% CI, 13.1-17.8) national infections. The subtype 6a in southern region and 3b and 3a in southwestern region had a higher proportion of infections than that in other regions. In addition, the genotypes 3 and 6 are already prevalent in almost all risk groups. The distribution of HCV genotypes were sharply shifting in China in the past three decades. The HCV subtype 1b posed a sharp decline, whereas genotypes 3 and 6 played an increasing role in the regional and populational HCV pandemic.

Anadromy and heterogenous population of a tropical shad Tenualosa ilisha in Malaysia, as revealed by otolith microchemistry and molecular evidence.

Tenualosa ilisha was found recently in the Perak River in western Peninsular Malaysia. Molecular phylogenetic and haplotype network analyses suggest that T. ilisha has two genetically distinct populations/groups: (i) Peninsular Malaysia (Malaysia population), and (ii) Peninsular Malaysia, Thailand, India and Bangladesh (Indian Ocean population). The results also suggest that the T ilisha population in Peninsular Malaysia is genetically heterogeneous with a typical anadromous migration pattern.

Epidemiology of Measles Cases in South Darfur State, Sudan, 2011-2015.

Case-based surveillance measles data was defined according to World Health Organization (WHO) guidelines. A total of 511 measles cases were studied from 2011 to 2015 in Southern Darfur State, Sudan and 58.1% of cases were confirmed from Nyala city. About 43.4% of cases were males, 56.6% of cases were female, and 47.7% were children under five years old. Similarity, within February to June, the cases increased by 8.0% in children vaccinated through measles campaign, and 5.3% in children that used child vaccination card and 78.7% in unvaccinated one. The epidemiologically linked (EPI-Linked) measles cases declined from 2011 to 2015; consequently, Measles still remain to be a significant challenge in south Darfur state, Sudan.

Identification of the Elusive Pyruvate Reductase of Chlamydomonas reinhardtii Chloroplasts.

Under anoxic conditions the green alga Chlamydomonas reinhardtii activates various fermentation pathways leading to the creation of formate, acetate, ethanol and small amounts of other metabolites including d-lactate and hydrogen. Progress has been made in identifying the enzymes involved in these pathways and their subcellular locations; however, the identity of the enzyme involved in reducing pyruvate to d-lactate has remained unclear. Based on sequence comparisons, enzyme activity measurements, X-ray crystallography, biochemical fractionation and analysis of knock-down mutants, we conclude that pyruvate reduction in the chloroplast is catalyzed by a tetrameric NAD(+)-dependent d-lactate dehydrogenase encoded by Cre07.g324550. Its expression during aerobic growth supports a possible function as a 'lactate valve' for the export of lactate to the mitochondrion for oxidation by cytochrome-dependent d-lactate dehydrogenases and by glycolate dehydrogenase. We also present a revised spatial model of fermentation based on our immunochemical detection of the likely pyruvate decarboxylase, PDC3, in the cytoplasm.

Life course and mental health: a thematic and systematic review.

Objective: This study explored the influence of the life course on mental health by identifying key trends, seminal works, and themes in existing research. Additionally, it highlights the major discussions at the intersection of life course and mental health. Methods: Documents were extracted from the Web of Science Core Collection (WoSCC), to systematically analyze themes on mental health outcomes across the life course. The analysis was based on key bibliometric tools, including VOSviewer 1.6.11, R Studio software, and GraphPad Prism 9 to analyze the evolution and impact of scholarly contributions in this domain. Results: The accumulated body of research concerning the life course's impact on mental health, which began to emerge around 1990 displayed a consistently upward trend. Predominant contributions originate from developed nations and frequently look into the psychosocial determinants of mental health over life course. Life course and mental health studies have been extensively infused with biopsychosocial frameworks that consider the role of genetic makeup, neurodevelopment, cognition, affect, sociocultural dynamics, and interpersonal relationships. Life course theory application in mental health highlight the substantive effects of accumulated adversities, notably social determinants of health, adverse childhood experiences (ACEs), and their implications for subsequent mental health outcomes. Conclusion: The nexus of life course and mental health outcomes demands further scholarly interrogation, particularly within underserved regions, to strengthen protective mechanisms for vulnerable populations.

Phenolic profiling and bioactivity assessment of in vitro propagated Psidium cattleianum Sabine: A promising study.

Psidium cattleianum Sabine (strawberry guava) is an evergreen shrub that is grown as a fruiting hedge and has received significant consideration in the food and pharmaceutical disciplines. This study aims to set a promising protocol for in vitro propagation of P. cattleianum, along with profiling the phenolic content of the original plant (OP), induced callus (IC), and regenerated plantlets (RP) extracts, ultimately, evaluating their anti-inflammatory, antioxidant, and anticancer potential. Seeds were treated with commercial bleaching, HCl, and H2O2 to enhance the germination percentage and minimize the contamination percentage. Culturing sterilized leaf explants onto Murashige and Skoog (MS) medium supplemented with benzyl adenine (BA), 2,4-dichloro phenoxy acetic acid, and kinetin showed the best callus induction, while supplementation of MS media with BA, adenine sulfate, naphthalene acetic acid, and gibberellic acid activated regeneration. Augmentation of MS media with indol-3-butyric acid recorded the maximum rooting percentage. Finally, the obtained rooted shoots were successfully acclimatized in sand and peat moss soil. HPLC-MS/MS profiles of OP, RP, and IC showed a variety of phenolic metabolites. IC extract decreased the viability of MCF-7, HepG2, and K-562 cancer cell lines. Also, OP exhibits strong antioxidant activity. P. cattleianum and its RP are profound sources of phenolic compounds promoted for promising applications in the food and pharmaceutical industries.

Anticoagulant effect of Feijoa sellowiana extracts generated by different biotechnological techniques.

Blood clotting has become one of the most dangerous side effects associated with Corona virus, as well as the high level of cholesterol and triglycerides in the blood. Therefore, it has become necessary to use medicinal plants that are biologically safe and containing anti-clotting compound. Feijoa sellowiana represents a prolific source diverse compounds that may have thrombolytic activity. Therefore, the main research point is the production and scaling up of a target contents that have anticoagulants by using biotechnological techniques; calli production, and bioreactors and assessed their activity through in-vivo study. Murashige and Skoog (MS) medium enriched with varying concentrations of benzyl adenine (BA) and naphthalene acetic acid (NAA) was used to cultivate calli and cell suspension cultures from F. sellowiana seeds. Bioreactors were employed to boost active constituent's production. Moreover, the bioreactor physical factors such as effect of controlled or uncontrolled pH medium were investigated. The leaves of the main plant were extracted by ethanol 70% and polar and non-polar extracts were also prepared. The ethanol extract of calli and cells resulting from bioreactors were also prepared. All prepared extracts were subjected to chemical analysis by HPLC, in-vitro antioxidant assays, in-vivo anticoagulant activity and histopathological examination. Calli and cell suspension cultures were produced by using MS medium fortified with 1 mg/L BA+ 0.1 mg/L NAA. It was found that culturing of cell cultures in a bioreactor with uncontrolled pH and aeration at the value of 0.5 L/min gave the maximum and economical fresh and dry weights of the plants. After evaluation of all extracts; it was found that the calli ethanol extract for each plant was the highest value of total phenolic and total flavonoid contents either quantitatively or qualitatively. All extracts of Feijoa had antioxidant activity. The IC50 of the DPPH of Feijoa calli extract was 13.45 µg/mL, it was also confirmed by FRAP and ABTs values. Feijoa calli extract decreased platelet aggregation by suppression of thrombin, extended aPTT, PT, bleeding and clotting times. It was safer than warfarin medication. From these findings the authors can conclude that Feijoa had highly anticoagulant activity and the calli production achieved the goal of the enhancement of the phenolic constituent and thus their activity.

Essential oils of Psidium cattleianum Sabine leaves and flowers: Anti-inflammatory and cytotoxic activities.

Introduction: Psidium cattleianum Sabine is a Brazilian native shrub cultivated for its edible fruit araçá (strawberry guava). P. cattleianum is recognized for health and food applications, although the essential oils (EOs) from the Egyptian inhabitant are not fully explored. The current study investigated the anti-inflammatory and cytotoxic activities of EOs from P. cattleianum leaves and flowers. Materials and methods: The EOs were obtained by three different methods viz; the conventional hydro-distillation, microwave assisted hydro-distillation, and supercritical fluid extraction, while their analysis was accomplished using GC/MS. The derived EOs were screened for their anti-inflammatory activity in the 5-lipoxygenase, COX-1, and COX-2 enzyme based assays, while the anticancer potential was deduced from MTT cytotoxic assay, cell cycle, and western blotting analysis. Results and discussion: Among other methods, supercritical fluid extraction offered the highest EO yield, 0.62% (leaves) and 1.4% (flowers). GC/MS identified ß-caryophyllene and α-humulene in both organs with high but variable percentages. The leaves demonstrated strong activity in inhibiting the 5-lipoxygenase enzyme (IC50 2.38), while the flowers, in inhibiting COX-2 (IC50 2.575). Moreover, the leaves showed potent, selective cytotoxicity to MCF-7 cells (IC50 5.32) via apoptosis by modulating the p53/Bax/Bcl2 axis. The deduced activities are possible due to the synergism between the volatile components that endorses P. cattleianum leaves' EOs in the management of breast cancer and inflammatory disorders.

Mitochondrial cytochrome c oxidase subunit I gene analysis of the yellowfin snapper, Lutjanus xanthopinnis in the Indo-Pacific region and a note on Lutjanus lutjanus population structure.

The yellowfin snapper, Lutjanus xanthopinnis, was recorded as a newly described species in the Indo-Pacific region in 2015. However, the knowledge of its biology, biogeography and ecology is scarcely understood, and, hence, its current conservation status is categorized as Data Deficient. The mitochondrial cytochrome c oxidase subunit I (COI) gene was examined to confirm species identification. We also examined the COI gene haplotypes of L. xanthopinnis in Brunei Darussalam and Malaysia together with other waters, i.e., Bangladesh, Indonesia, Japan, Singapore, Sri Lanka and Taiwan. Our molecular analyses found that Brunei Darussalam and eastern Peninsular Malaysia samples were genetically similar. However, the former showed higher genetic diversity than the latter. The samples from these two sites also showed signatures of population expansion. Furthermore, identical haplotypes could be found in different locations, suggesting the absence of spatial genetic structure. On the other hand, Lutjanus lutjanus showed a population structure associated with geographical locations, i.e., western Pacific Ocean, Indian Ocean and Maluku in Indonesia.

Factors associated with COVID-19 vaccine uptake among foreign migrants in China.

Background/Purpose: The COVID-19 outbreak created unique policy challenges for vaccinating special groups like migrants. As part of sustainable development goals, the equitable distribution of the COVID-19 vaccine can contribute to ensuring health for all. This study examined COVID-19 vaccine uptake among foreign migrants in China based on sociodemographics, cultural beliefs, past vaccine behaviors, and psychosocial factors. Design: An online cross-sectional survey was conducted among foreign migrants in mainland China via social media platforms from 21 November through 20 December 2021. Bivariate (unadjusted odd-ratio) and multivariate logistic regression analyses were performed to establish the correlates of COVID-19 vaccine uptake. Result: Surveyed foreign migrants that are culture neutral (AOR: 2.5, CI: 95%, 1.02-5.90, p = 0.044), willing to pay for vaccination (AOR: 2.27, CI: 95%, 1.18-3.98, p = 0.012), believe in vaccine efficacy (AOR: 3.00, CI: 95%, 1.75-5.16, p < 0.000), have poor psychological health (AOR: 1.96, CI: 95%, 1.14-3.38, p = 0 0.014), and have higher perceived seriousness of COVID-19 (AOR: 2.12, CI: 95%, 1.26-3.57, p = 0.005) are more likely to receive COVID-19 vaccine. Those migrants with a history of declining vaccination (AOR: 0.34, CI: 95%, 0.18-0.65, p = 0.000) and middle-income earners $1701-3500 (AOR: 0.43, CI: 95%, 0.23-0.82, p = 0.010) are less likely to receive the COVID-19 vaccine. Conclusion: This study brings a unique perspective to understanding vaccine behavior among international migrants in China. There is an urgent call from the World Health Organization and countries for complete vaccination and efforts to improve vaccine coverage. However, fewer studies have been conducted globally on the vaccination of migrant populations. The current study provides empirical information to increase the knowledge of the correlates of vaccine behavior among immigrants in countries around the globe. Future studies should conduct cross-country comparisons to understand the factors associated with increasing vaccination rates among immigrant populations to formulate a strong policy to increase vaccine coverage among immigrant populations across countries.

Social integration, solidarity, and psychological health of internally displaced persons in Cameroon: Exploring the role of community satisfaction.

Background/Introduction: Conflict-induced displacement continue to be a pressing public policy concern due to the adverse effects on the well-being of internally displaced persons (IDPs). Understanding the integration process of these individuals, particularly the role of solidarity and social integration in fostering a sense of belonging and improving their community experiences and psychological well-being, remains unclear. This study investigates the role of community satisfaction in the relationship among social integration, solidarity, and psychological health of IDPs in Cameroon. Methods: Cross-sectional data from 428 displaced individuals in the Ntui subdivision, Cameroon, were analyzed using structural equation modeling (SEM). This technique tested four latent variables: social integration, solidarity, community satisfaction, and psychological health. Results: The results show a direct association between solidarity and both community satisfaction (ß = 0.282; p < 0.001) and psychological health (ß = 0.137; p < 0.01). Community satisfaction also has a direct relationship with the psychological health of the IDPs (ß = 0.292; p < 0.001). An indirect effect of solidarity on psychological health through community satisfaction was observed (ß = 0.084 (SE = 0.025, CI = [0.047, 0.129], p < 0.001)). However, no mediational effect of community satisfaction was found on the association between social integration and psychological health. The model accounted for 7% of the variance in community satisfaction (R2 = 0.07) and 20% of the variance in psychological health (R2 = 0.20). Conclusion: The findings indicate a strong sense of solidarity among the displaced persons in the studied communities in Cameroon, which promotes their psychological health via community satisfaction. As such, interventions should aim to foster solidarity among displaced persons to enhance their community experiences and psychological health.
