Individual differences in drug response have always existed in clinical treatment. Many non-genetic factors show non-negligible impacts on personalized medicine. Emerging studies have demonstrated epigenetic could connect non-genetic factors and individual difference in treatment. We used systematic retrieval methods and reviewed studies that showed individual factors’ impact on DNA methylation of ADME genes. In total, 63 studies were included, and half(n=32) were cohort studies. Six aspects of individual factors were summarized from the perspective of personalized medicine: parental exposure, environmental pollutants exposure, obesity and diet, drugs, gender and others. The largest number of studies (n=11) studied methylation of ABCG1. Most studies showed these non-genetic factors could result in a significant DNA methylation alteration in ADME genes, which subsequently affect the process of drug metabolism. However, the underlying mechanisms remain unknown. Finally, we put forward some views for future research.

Objectives: Chronic obstructive pulmonary disease (COPD) affects a large part of the population around the world between the ages forty-one to seventy-one years. However, by combining the effects of the COVID-19 pandemic and the SARS-Cov-2 virus on COPD patients, we may be able to overcome factors that have a significant impact on our success. Moreover, we have to investigate the relationship between the diagnosis and its influencing factors to possibly overcome the emerging causes of this disease. Methods: A retrospective study of 280 patients was conducted at DHQ Hospital Muzaffargarh in Punjab, Pakistan. Negative binomial regression describes the risk of fixed successive variables. Cox proportional hazard model, and the model co-efficient is observed using log-likelihood. Kaplan-Meier curves showed how long COPD patients survived or died. Results: The increased risk of death in COPD patients was due to the effects of variables such as cough, lower respiratory tract infection, tuberculosis, and body aches being 1.369, 0.693, 0.170, and 0.217 times higher, while it decreased by 0.396 in normal conditions. Conclusion: We found that the symptoms of COPD (cough, lower respiratory tract infection, tuberculosis, and body aches) are statistically significant in patients who were most infected by COVID-19 and SARS-Cov-2.

As one of the most urgent social and health problems in the world, neurological diseases have always been attracted by researchers. However, the pathological mechanisms and therapeutic approach are not achieved. In addition to the established roles of oxidative stress, inflammation and immune response, the changes of gut microbiota are also closely related to the development of neurological diseases. Emerging insights on the roles of gut microbiota have confirmed its indispensability in the development of neurological diseases, including neurodegenerative diseases and neuropsychiatric diseases. The dynamic bidirectional communication pathway between gut microbiota and central nervous system is called “gut-brain axis”, which involves immune, metabolic and neural pathways. In this review, we discussed the complex relationship between gut microbiota and the central nervous system from the perspective of gut-brain axis, reviewed the mechanism of microbiota in different neurological diseases, and prospected the employment of gut microbiota in the therapeutic approach of those diseases.

Purpose:Chronic corneal pain is the most common symptom of dry eye disease (DED), while the central sensitization mechanisms underlying remain unclear. Methods:Excision of extra orbital lacrimal glands was used to establish dry eye (DE) model. Tear volume measurements, corneal fluorescein staining, corneal hypersensitivity and anxiety behavior were tested after surgery. The amplitude of low-frequency fluctuation (ALFF) by fMRI was used for determining brain functional activity. C-Fos, Brain-derived neurotrophic factor (BDNF), and cytokine levels in corresponding brain regions were tested. Results:Compared to the Sham group, the ALFF signals in the supplemental somatosensory area, secondary auditory cortex, agranular insular cortex, temporal association areas, and ectorhinal cortex brain areas were enhanced in DE group. ALFF signal in the insular cortex was related to corneal hypersensitivity (p < 0.01). C-Fos (P < 0.001), BDNF (P < 0.01), TNF-α, IL-6 and IL-1β (P < 0.05) increased, while IL-10 levels (P < 0.05) decreased in the insular cortex in the DE group. Surgery-induced corneal hypersensitivity and upregulation of inflammatory cytokines, but not anxiety, could be blocked by insular cortex injection of Tyrosine Kinase receptor B (TrkB) agonist cyclotraxin-B (P< 0.01). Conclusions :This research presents the map of functional brain by ALFF through rs-fMRI associated with chronic corneal pain. BDNF-TrkB signaling-related neuroinflammation in the insular cortex might contribute to dry eye-related chronic corneal pain. This measure could potentially help clinicians improve therapeutic approach to pain control and development of diagnostic approach.

Spinal cord injury (SCI) causes permanent damage and has a high disability rate. Currently, no efficient therapeutic strategy is available for SCI. This study investigated the mechanisms of microRNAs (miRNAs) in rats with spinal cord injury. Whole transcriptome sequencing (WTS) was used for analyzing miRNA and messenger RNA (mRNA) expression patterns in rat spinal cord tissue at different time points after SCI. Gene Ontology (GO) and KEGG pathways were analyzed to obtain crucial functional pathways. miR-6315 was the most significantly upregulated and differentially expressed miRNA after 24 h of SCI; the expression of miR-6315 gradually decreased after 3 and 7 days of SCI. Bioinformatics analysis was conducted to predict the targeting relation of miR-6315 with Smo, and qRT-PCR and dual-luciferase reporter assays were conducted for verification. We successfully injected miR-6315 low-expressing adenovirus into the center of the spinal cord lesion and successfully infected glutamate (Glu)-treated primary spinal neurons with miR-6315 low-expressing adenovirus. miR-6315 knockdown treatment significantly promoted functional behavioral recovery in rats post-SCI through using Basso-Beattie-Bresnahan (BBB) locomotor rating scale and the inclined plane test. The neuronal axon regeneration and neuronal migration were promoted, and cell apoptosis was attenuated in treated SCI rats and Glu-treated neurons after miR-6315 knockdown using immunofluorescence and scratch assays. We discovered that Smo and anti-ferroptosis pathway factors, xCT, GSH, and GPX4, may be involved in miR-6315-regulated SCI repair. The expression of miR-6315 was negatively correlated with Smo, xCT, GSH, and GPX4. In conclusion, miR-6315 may be a potential target in the treatment of SCI.

Complex PTSD (CPTSD) is a new diagnosis in the World Health Organization (WHO)’s International Classification of Diseases (ICD-11). This case study describes the delivery of Skills Training in Affective and Interpersonal Regulation and Narrative Therapy (SNT), a flexible, multi-component therapy that addresses the symptoms of CPTSD. SNT balances interventions that address current day stressors with those that reappraise the meaning of traumatic past events. This paper outlines 16 sessions of SNT with a 55-year-old gay man. The treatment introduces client tailored coping skills for current minority stress, discrimination and micro-aggressions as well as trauma-focused interventions regarding events from his childhood and the death of his partner and many members of his community due to the AIDS epidemic. Qualitative and quantitative outcomes are summarized. Implications regarding the relevance of SNT for sexual and gender minority (SGM) individuals is discussed.

In recent years, health care providers have seen an increase in the number of patients with difficult-to-treat wounds and burns. The bio polymer-based wound dressing shields the injured part and aids in the recapture of epithelial and dermal tissues throughout the process of healing. The total count of a person with chronic lesions has been expanding whole due to developing society, over weight and cardiovascular illness. The development of ideal wound dressing material with excellent characteristics like antimicrobial activity, biocompatibility, free radical scavenging capacity, non-adherent property, the hydrophilicity of alginate, cellulose, chitosan, collagen has an increasing demand for the treatment of chronic wounds. Nevertheless, owing to the above mention property, natural polymers are being used for several key functions of biomedicine like narcotic distribution systems, tissue manufacturing, bandages etc. accordingly, the significance of these bio-based polymers interfered with healing functions that lead to inform and inspire youth and scientist researchers worldwide to grab with these far-reaching areas of medicine and biology. The review highlights the physiochemical property of natural polymer, biological evaluation of various materials as wound dress, along with their synthesis and mechanical properties, clinical status, challenges and future perspectives.

A large part of the soil protist diversity is missed in metabarcoding studies based on 0.25 g of soil environmental DNA (eDNA) and universal primers due to ca. 80 % co-amplification of non-target plants, animals and fungi. To overcome this problem, enrichment of the substrate used for eDNA extraction is an easyly implemented option but its effect has not yet been tested. In this study, we evaluated the effect of a 150 µm mesh size filtration and sedimentation method to improve the recovery of protist eDNA, while reducing the co-extraction of plant, animal and fungal eDNA, using a set of contrasted forest and alpine soils from La Réunion, Japan, Spain and Switzerland. Biodiversity of the whole eukaryotic community was estimated with V4 18S rRNA metabarcoding and classical amplicon sequence variant calling. A 2-3-fold enrichment in shelled protists (Euglyphida, Arcellinida and Chrysophyceae) was observed at the sample level with the proposed method, with, at the same time, a 2-fold depletion of Fungi and a 3-fold depletion of Embryophyceae. Protist alpha diversity was slightly lower in filtered samples due to reduced coverage in Variosea and Sarcomonadea, but significant differences were observed in only one region. Beta diversity was mostly impacted by region and habitat, and explained the same variance in bulk soil and filtered samples. The increase resolution in the soil protist diversity provided by the filtration-sedimentation method is a strong argument to include it in the standard preparation of any future soil for protist eDNA metabarcoding studies.

The paper presents studies of polymer-fullerene matrix-dopped CdSe/ZnS nanodots for application in organic solar cells. As a reference active layer, poly(3-hexylthiophene-2 5-diyl) and 6,6-phenyl-C71-butyric acid methyl ester arrangement was used. Absorption and luminescence spectra were determined for CdSe/ZnS quantum dots. The dispersion relations for optical constants were determined for pure quantum dots and matrixes using ellipsometric spectroscopy. The morphologies of the thin film layers were performed using Atomic Force Microscope (AFM). Chemical boundings for ternary layers were obtained by Raman spectroscopy. Based on UPS studies, the energy diagram of the potential devices was determined. Impedance spectroscopy studies were also performed to obtain layers resistance. The performance results of organic cells with donor active layers doped with quantum dots were obtained using General-Purpose Photovoltaic Device Model (GPVDM) software.

The increase in asthma cases in Pakistan after the flood of 2022 has confirmed that the condition is a serious public health hazard. The production of fungus spores on moist surfaces and in humid environments is a significant factor in asthma onset. In this study, we discuss the distinctive seasonality and mechanism of fungal spore occurrence in Pakistan. Epidemic areas are those that are characterized by intermittent outbreaks, are close to local rivers, or have humid environments that are conducive to the formation of molds and fungus spores. Heavy rain promotes the interaction between contaminated water and human activity, which can lead to an increase in sporogenesis which is directly linked to a number of asthmatic patients. We studied the association between exposure to pluvial floodwater, production of fungal spores, and its impact on the respiratory condition “Asthma”

IntroductionThe wildlife trade is a major societal issue challenging both biodiversity conservation and global health (Bezerra-Santos et al., 2021; Hughes, 2021). At an estimated annual value of several US$ trillions, it also constitutes a crucial –often parallel– economy for countries, in which actors of the supply-chain source their revenues (Andersson et al., 2021). It is also an important food system for a number of rural households across the tropics (Fa et al., 2016).The advent of the COVID-19 pandemic has generated a vivid debate on whether or not the wildlife trade should be banned. Contrasting calls from and within the scientific community, the political spheres and the public have been put forward (Fang et al., 2021), from an outright permanent ban (Sills et al., 2020) to maintenance of the wildlife trade for the sake of social development (Roe et al., 2020).West and central African rainforests are a particular hotspot for the wildlife trade, where bushmeat –the terrestrial vertebrates hunted for food– has traditionally been a vital source of protein and income for rural communities (Ingram et al., 2021). With the globalization of the trade, bushmeat offtakes have become likely unsustainable for many species (reaching c. 5 million tons each year; Nasi et al., 2011), an extinction trend coined under the term “bushmeat crisis” (Bennett et al., 2002).With the COVID-19 pandemic, the African continent was struck by national trade bans of various length and effectiveness (Harvey-Carroll et al., 2022; Meseko et al., 2020). However, because the bushmeat trade is a poorly regulated, parallel economy across most of Africa, the genuine economic stakes behind the trade are poorly known (van Vliet et al., 2017). Moreover, the impact of bans on trade activities has rarely been quantified (but see Funk et al., 2022), notably in terms of post-ban recovery.We conducted long-term monitoring of bushmeat sites in Côte d’Ivoire (West Africa) that encompassed pre-, during, and post-COVID-19 lockdown. In Côte d’Ivoire, hunting has been illegal since 1974 (law n°94–442), but the bushmeat trade is openly tolerated, notably in major urban zones (Gossé et al., 2022). Quantitative data on the bushmeat trade are scarce and mostly outdated, but large levels of supply from protected areas has been observed recently (Bi Gonedelé et al., 2017; Bi Gonedelé et al., 2022). The trade seems non-selective in terms of species and strictly motivated by financial income (Gossé et al., 2022), highlighting both the likely unsustainability and important economic role of the national bushmeat trade network.Controls of the bushmeat trade by Ivorian state agencies have been regularly implemented as conservation-oriented measures or public health emergencies after the earlier epidemic of Ebola virus disease in 1994 (Dindé et al., 2017). However, there is to date no information available on how such control measures have affected the market. Our main objective was to assess the dynamics of the bushmeat trade in Côte d’Ivoire as a response to the COVID-19 pandemic and explore post-lockdown recovery trends depending on market type. We posit that (i) bushmeat trade dynamics was negatively impacted by governmental measures, with trends being similar between market types (as a measure of the effectiveness of government interventions), and that (ii) bushmeat trade activities quickly recovered after the lockdown –and the bushmeat ban– were lifted (as a measure of market network resilience).

Purpose: Narrow therapeutic index (NTI) drugs must be routinely monitored for their severe effects. These drugs share some common features and criteria that focus on the separation of safety and efficacy in relation to toxicity and efficacy. Methods: There are many factors that contribute to drugs’ high toxicity and lack of efficacy, including the following 5: right drug, right dose, right time, right duration, right age. Results: It’s reviewed over 200 drugs, focusing on NTI drugs’ clinical pharmacology, dose-response relationship, physiochemical properties, and potential drug-drug interactions. It is found that any minor change in therapeutic drug concentrations or doses may have significant consequences for patients, such as bleeding due to warfarin overdose or thrombotic events due to underdose. Conclusions: For NTI drugs, therapeutic drug monitoring (TDM) must be accessible in all hospitals and outpatient clinics to ensure patient safety. These approaches and methods must be done in each patient.

Rainwater is a vital resource and dynamic driver of terrestrial ecosystems. Yet, processes controlling precipitation inputs and interactions during storms are often poorly seen, and poorly sensed when direct observations are substituted with technological ones. We discuss how human observations complement technological ones, and the benefits of scientists spending more time in the storm. Human observation can reveal ephemeral storm-related phenomena such as biogeochemical ‘hot moments’, organismal responses, and sedimentary processes which can then be explored in greater resolution using sensors and virtual experimentation. Storm-related phenomena trigger lasting, oversized impacts on hydrologic and biogeochemical processes, organismal traits/functions, and ecosystem services. We provide examples of phenomena in forests, across disciplines and scales, to inspire mindful, holistic observation of ecosystems during storms. We conclude that technological observations alone are insufficient to trace the process complexity and unpredictability of fleeting biogeochemical or ecological events without the “shower thoughts” produced by scientists’ human sensory and cognitive systems during storms.

Objective: To evaluate the changes of fetal epicardial fat thickness (EFT) in pregnancies with pregestational (PGDM) and gestational diabetes mellitus (GDM) and to identify the diagnostic effectiveness of fetal EFT in differentiating PGDM and GDM from normal pregnancies. Methods: The study was conducted with pregnant women who admitted to perinatology department between November 2020 and September 2022. Patients were analyzed as 3 groups: PGDM (n=161), GDM (n=171) and control group (n=170). EFT was measured in all three groups at 29 weeks of gestation. Demographic characteristics and ultrasonographic findings were recorded and compared. Results: The mean fetal EFT was significantly higher in PGDM (1.47±0.083 mm, p<0.001) and GDM (1.40±0.082 mm, p<0.001) groups compared to control group (1.19±0.049 mm) and was also significantly higher in PGDM group than GDM group (p<0.001). Fetal EFT was significantly positively correlated with maternal age, fasting, 1 st hour, 2 nd hour glucose values, HbA1c, fetal abdominal circumference and deepest vertical pocket of amniotic fluid (p<0.001). Fetal EFT value of 1.3 mm diagnosed PGDM patients with a sensitivity of 97.3% and a specificity of 98.2%. Fetal EFT value of 1.27 mm diagnosed GDM patients with a sensitivity of 94% and a specificity of 95%. Conclusions: Fetal EFT is greater in pregnancies with diabetes than in normal pregnancies, and also greater in PGDM than in GDM. In addition, fetal EFT is strongly correlated with maternal blood glucose levels in diabetic pregnancies.

Background: The prevalence of asthma in Bangladesh is about 7%. The spirometric values in healthy children were obtained in a single urban school more than a decade ago. No rural data is available till date. Objective: To determine the spirometric values of healthy school going children in three rural schools of Bangladesh. Materials and Methods: This cross-sectional study was carried out from July 2019 to June 2020 among 300 healthy children among both boys and girls aged 11 to 15 years in three rural schools. Among 350 approached students 332 students responded to the study, 18 students did not meet inclusion criteria and 14 students could not follow spirometry procedure. Informed written consent was taken from guardians. History regarding socio-demographic profile, passive smoking, concurrent or past respiratory illness and medication were taken and weight, height and BMI were measured of the children. Spirometry was done with spirometer machine and reports were generated by software installed in a laptop. Results: Boys showed higher FVC, FEV1 and PEFR but lower FEV1/FVC ratio than those of girls. Regression equations for lung function values were determined for boys and girls considering height as independent variable. Conclusions: Spirometric indices were higher in boys than those of girls and they tended to increase with height, except FEV1/FVC ratio that was higher in girls with a negative correlation with height.

January 04, 2023
The COVID-19 pandemic has had a widespread impact on a global scale, and the evolution of considerable dominants has already taken place. Some variants contained certain key mutations located on the receptor binding domain (RBD) of spike protein, such as E484K and N501Y. It is increasingly worrying that these variants could impair the efficacy of current vaccines or therapies. Therefore, how to design future vaccines to prevent the different variants remains urgent. In this work, we proposed an in silico approach, in which we combined binding free energy measured by computational mutagenesis of spike-antibody complexes and mutation frequency calculated from viral genome sequencing data, to estimate an immune-escaping score ( IES) and predict immune-escaping hot spots. We identified 23 immune-escaping mutations on the RBD, nine of which occurred in omicron variants (R346K, K417N, N440K, L452Q, L452R, S477N, T478K, F490S, and N501Y), despite our dataset being curated before the omicron first appeared. The highest immune-escaping score ( IES=1) was found for E484K, which agrees with recent studies stating that the mutation significantly reduced the efficacy of neutralization antibodies. Furthermore, our predicted binding free energy and IES show a high correlation with high-throughput deep mutational scanning (Pearson’s r = 0.70) and experimentally measured neutralization titers data (mean Pearson’s r = -0.80). In summary, our work provides valuable insights and will help design future COVID-19 vaccines.

January 04, 2023
Past studies have evinced that the perception of near-hand objects is qualitatively different from that of far-hand objects. However, as the influence of test anxiety during tasks of visual processing has never been considered, this study aims to assess whether the presence of hand alters/biases the visual processing of objects while controlling for the effect of test anxiety. A sample of 30 participants aged 22-55 years old was recruited through convenience sampling and performed a cognitive task based on the Posner paradigm of Inhibition of Return (Posner et al., 1985) during which they held their hand on their lap in the control condition and next to the screen in the experimental one. Their test anxiety was assessed retroactively through the Test Anxiety Profile (Oetting & Deffenbacher, 1980, as cited in Gass and Curiel, 2011). A correlation was performed between test anxiety and Reactions Times (RTs) scores, and an analysis of variance was computed with the presence of the hand and the validity of trials as independent variables and RTs as the dependent variable. Next, an analysis of covariance included test anxiety as the covariate. The presence of the hand altered/biased the visual processing of stimuli, and participants shifted their attention between items faster in the experimental condition. Participants’ test anxiety did not mediate the near-hand effect. This study provides insights into the development of multitouch devices and their applications in the educational setting.

Gastrointestinal (GI) tract bleeding can present as symptomatic anemia in children. This presentation warrants evaluation for GI tract pathology and consideration of coagulation assays to rule out an underlying bleeding diathesis. A male child was diagnosed with a rare bleeding disorder, severe (<1%) factor VII (FVII) deficiency during evaluation of severe iron deficiency anemia (IDA) secondary to recurrent GI bleeding. Despite adequate prophylaxis for the underlying bleeding disorder, continued GI bleeding and anemia led to further evaluation and identification of a rare small intestinal tract lesion, heterotopic gastric mucosa (HGM). Surgical treatment of the lesion resulted in complete symptom resolution and abated the need for prophylactic factor replacement therapy.

Background: Pain is the clinical hallmark of sickle cell disease (SCD) leading to hospitalization, psychological sequelae and a decreased health-related quality of life. The aim of this systematic literature review is to evaluate the efficacy of non-pharmacological interventions in reducing sickle cell-related pain in children with SCD. Methods: A comprehensive literature search up until October 2022 was performed to identify studies that investigated the efficacy of non-pharmacological interventions on (1) pain frequency and/or intensity, and (2) analgesic and health service use in children with SCD. Randomized controlled (RCTs) trials and quasi-experimental designed (QED) studies that investigated non-pharmacological interventions for pediatric patients with SCD until the age of 21 years were considered for inclusion. Results: Ten articles (5 RCTs and 5 QED studies) with 422 participants were included. They investigated cognitive behavioral therapy (CBT) (n =5), biofeedback (n=2), massage (n=1), virtual reality (n=1) and yoga (n=1). CBT, biofeedback, massage, virtual reality and yoga significantly reduced frequency and/or intensity of SCD-related pain. Biofeedback also significantly reduced analgesic use. Conclusion: Non-pharmacological interventions may be effective in reducing pain in pediatric SCD patients. However, due to the heterogeneity of the included studies a quantitative analysis could not be performed. Awaiting further supporting evidence, healthcare providers should consider implementing these interventions as valuable part of a comprehensive pain management strategy plan to improve the outcome of sickle cell-related pain.
