Authors: Liu Zhuoen , Zuo Yiming , Feng Gang 
Published: August 2024

AbstractAimsPrimary forests provide critical habitat and diverse ecological niches for bird species, which are being seriously threatened by massive anthropogenic activities in the Anthropocene. Conversion from primary forests to secondary forests and plantation forests results in biodiversity loss, reducing ecosystem functioning and services. However, few studies have evaluated bird diversity patterns in different forest types caused by anthropogenic activities at both pantropics and regional scales, especially from taxonomic, phylogenetic and functional perspective simultaneously, as well as from the perspective of both alpha and beta diversity.LocationPantropics.MethodsWe analysed patterns of bird diversity in primary forests, secondary forests and plantation forests at pantropics and regional scales. Number of threatened species, rare species, and generalist species in the three forest types were summarized. Taxonomic, phylogenetic and functional diversity, as well as phylogenetic and functional structure of bird communities among the three forest types, were evaluated through multiple comparisons. Beta diversity of bird communities in the three forest types was also calculated and decomposed into turnover and nestedness‐resultant components, and correlations between environmental factors and beta diversity were examined.ResultsThe results showed that primary forests harboured more threatened species, more large species and specialist species than secondary forests and plantation forests. In addition, plantation forests had lower phylogenetic alpha diversity but higher functional alpha diversity, and had more clustered phylogenetic structure but more over‐dispersed functional structure. Notably, taxonomic, phylogenetic and functional beta diversity of bird communities was significantly higher in primary forests than in plantation forests, and turnover components showed similar patterns and accounted for major parts of overall beta diversity.Main ConclusionsThese findings suggest that primary forests play an important role in protecting bird taxonomic, phylogenetic and functional diversity, and emphasize that future conservation efforts should focus on the strict protection of primary forests.

AbstractMetastasis is a crucial stage in tumour progression, and cancer‐associated fibroblasts (CAFs) support metastasis through their participation in extracellular matrix (ECM) stiffness. CD248 is a possible biomarker for non‐small cell lung cancer (NSCLC)‐derived CAFs, but its role in mediating ECM stiffness to promote NSCLC metastasis is unknown. We investigated the significance of CD248+ CAFs in activating the Hippo axis and promoting connective tissue growth factor (CTGF) expression, which affects the stromal collagen I environment and improves ECM stiffness, thereby facilitating NSCLC metastasis. In this study, we found that higher levels of CD248 in CAFs induced the formation of collagen I, which in turn increased extracellular matrix stiffness, thereby enabling NSCLC cell infiltration and migration. Hippo axis activation by CD248+ CAFs induces CTGF expression, which facilitates the formation of the collagen I milieu in the stromal matrix. In a tumour lung metastasis model utilizing fibroblast‐specific CD248 gene knockout mice, CD248 gene knockout mice showed a significantly reduced ability to develop tumour lung metastasis compared to that of WT mice. Our findings demonstrate that CD248+ CAFs activate the Hippo pathway, thereby inducing CTGF expression, which in turn facilitates the collagen I milieu of the stromal matrix, which promotes NSCLC metastasis.

ABSTRACTThe woody bamboos (Bambusoideae) exhibit distinctive biological traits within Poaceae, such as highly lignified culms, rapid shoot growth, monocarpic mass flowering and nutlike or fleshy caryopses. Much of the remarkable morphological diversity across the subfamily exists within a single hexaploid clade, the paleotropical woody bamboos (PWB), making it ideal to investigate the factors underlying morphological evolution in woody bamboos. However, the origin and biogeographical history of PWB remain elusive, as does the effect of environmental factors on the evolution of their morphological characters. We generated a robust and time‐calibrated phylogeny of PWB using single nucleotide polymorphisms retrieved from optimized double digest restriction site associated DNA sequencing, and explored the evolutionary trends of habit, inflorescence, and caryopsis type in relation to environmental factors including climate, soil, and topography. We inferred that the PWB started to diversify across the Oligocene–Miocene boundary and formed four major clades, that is, Melocanninae, Racemobambosinae s.l. (comprising Dinochloinae, Greslanlinae, Racemobambosinae s.str. and Temburongiinae), Hickeliinae and Bambusinae s.l. (comprising Bambusinae s.str. plus Holttumochloinae). The ancestor of PWB was reconstructed as having erect habit, indeterminate inflorescence and basic caryopsis. The characters including climbing/scrambling habit, determinate inflorescence, and nucoid/bacoid caryopsis have since undergone multiple changes and reversals during the diversification of PWB. The evolution of all three traits was correlated with, and hence likely influenced by, aspects of climate, topography, and soil, with climate factors most strongly correlated with morphological traits, and soil factors least so. However, topography had more influence than climate or soil on the evolution of erect habit, whereas both factors had greater effect on the evolution of bacoid caryopsis than did soil. Our results provide novel insights into morphological diversity and adaptive evolution in bamboos for future ecological and evolutionary research.
Transcription factor 7‐like 2 (TCF7l2) regulates CNS myelination separating from its role in upstream oligodendrocyte differentiation

Published: August 2024

AbstractOligodendrocyte progenitor cells (OPCs) differentiation into oligodendrocytes (OLs) and subsequent myelination are two closely coordinated yet differentially regulated steps for myelin formation and repair in the CNS. Previously thought as an inhibitory factor by activating Wnt/beta‐catenin signaling, we and others have demonstrated that the Transcription factor 7‐like 2 (TCF7l2) promotes OL differentiation independent of Wnt/beta‐catenin signaling activation. However, it remains elusive if TCF7l2 directly controls CNS myelination separating from its role in upstream oligodendrocyte differentiation. This is partially because of the lack of genetic animal models that could tease out CNS myelination from upstream OL differentiation. Here, we report that constitutively depleting TCF7l2 transiently inhibited oligodendrocyte differentiation during early postnatal development, but it impaired CNS myelination in the long term in adult mice. Using time‐conditional and developmental‐stage‐specific genetic approaches, we further showed that depleting TCF7l2 in already differentiated OLs did not impact myelin protein gene expression nor oligodendroglial populations, instead, it perturbed CNS myelination in the adult. Therefore, our data convincingly demonstrate the crucial role of TCF7l2 in regulating CNS myelination independent of its role in upstream oligodendrocyte differentiation.

Published: August 2024

AbstractBackground and AimsLeprosy is a chronic infectious disease caused by Mycobacterium leprae (M. leprae), an intracellular bacillus that systematically invades the peripheral nerves. Diagnosing leprosy neuropathy is still a defying skill, and late diagnosis and treatment are still a reality. Based on the biological characteristics of M. leprae, particularly its preference for invading the Schwann cells localized at the coldest areas of human body, we hypothesized that these areas have focal demyelination that may escape detection through standard nerve conduction studies (NCSs) protocols.MethodsTwenty‐five patients with confirmed multibacillary leprosy and 14 controls were accessed. A multisegmented NCS protocol (MP) was performed, targeting short segments through the coldest areas, to identify focal areas of slowed conduction velocity. The effectiveness of this multisegmented protocol was compared to the standard protocol (SP) to detect abnormalities.ResultsAll leprosy patients presented an abnormal study with the MP, contrasting to 19 with the SP. The most frequent NCS pattern was an asymmetric neuropathy with focal slowing of conduction velocity, found in 23 out of 25 leprosy patients. Significant differences favoring the proposed method were observed when comparing the MP with the SP. Notably, the MP increased the sensitivity to detect abnormalities by 122%, 133%, and 257% for the median, peroneal, and tibial nerves, respectively. MP also increases sensitivity to detect focal abnormalities in the ulnar nerve.InterpretationThe MP protocol significantly increases the sensitivity of NCSs to detect neurophysiological abnormalities in leprosy neuropathy.

Published: August 2024

AbstractBackgroundThe family caregivers as primary caregivers play a crucial role regarding the care of cancer patients. As defined in the literature, the care burden encompasses the negative objective and subjective outcomes including psychological and physical health problems, economic and social issues, deterioration of family relationships and feelings of loss of control that arise from caregiving responsibilities.AimsThis study aims to assess the care burden and to evaluate the associated factors among family caregivers of cancer patients receiving treatment at a state hospital in Türkiye.MethodsThis cross‐sectional study was conducted with the family caregivers of patients undergoing treatment in the radiation oncology department of a state hospital in Türkiye. The study population consisted of 350 individuals, with a participation rate of 80%. Participants were administered a questionnaire concerning determining daily living activities and identifying the caregiving burden through their socio‐demographic characteristics.ResultsThe care burden among primary family caregivers while the delivery of health services was severe for 85.1% of them. The average ZBI score of caregivers was 55.92 ± 14.58. It was clarified that family caregivers' burden was influenced by several factors, including the duration of caregiving, difficulties experienced while caring for the patient, and the negative impact on their daily roles.ConclusionOur study's findings indicate the need for health professionals to support caregivers of cancer patients while over half of the caregivers were identified as having a severe level of caregiving burden. It is important to raise awareness among nurses and the oncology team with a holistic approach. In the delivery of health services, caregivers' needs should be identified first, support mechanisms should be activated and interventions should be made to meet these needs.ImpactThis study's findings highlight the need to identify and problems faced by family members during caregiving. This is important for sustainable and cost‐effective holistic care.Reporting MethodThe results of this study are reported based on the guidelines of The Strengthening the Reporting of Observational Studies (cohort, case–control studies, cross‐sectional studies) in Epidemiology (STROBE).Implications for practiceOur study's findings indicate the need for health professionals to support caregivers of cancer patients. It is important to raise awareness among nurses and the oncology team with a holistic approach. In the delivery of health services, caregivers' needs should be identified first, support mechanisms should be activated and interventions should be made to meet these needs.

Published: August 2024

AbstractBackgroundBurning mouth syndrome (BMS) is a chronic pain condition affecting the oral cavity. This condition mostly affects peri‐ or postmenopausal women; for this reason, sexual hormonal changes have been implicated in BMS pathogenesis.MethodsA systematic review was performed in MEDLINE/PubMed, Scopus, Web of Science, Cochrane Library and EMBASE without restriction for language or year. Eligibility criteria were controlled studies addressing the PICO question: (P) patients with BMS; (I) detection of the sex hormones; (C) patients without BMS; (O) changes on sexual hormones as a risk factor for BMS severity. Risk of bias was performed with Newcastle‐Ottawa Quality Assessment Scale.ResultsFour studies were included. Salivary levels were evaluated in three studies and serum blood was used in one. Three studies analysed oestradiol and/or dehydroepiandrosterone (DHEA), two assessed progesterone and one evaluated follicle‐stimulating hormone (FSH). Oestradiol results were contradictory, with two studies reporting lower levels in BMS patients compared to controls and one finding the opposite. DHEA was statistically lower in the BMS group in one study. Progesterone showed opposite results in two studies, although none with statistical significance. FSH was statistically higher in the BMS group compared to controls. Correlation of hormones with quality of life was performed in three studies and there was no significant correlation with self‐perceived symptoms severity.ConclusionSexual hormones can be altered in BMS, especially oestradiol. Despite these changes, we did not find correlation between hormone fluctuation and BMS symptoms intensity affecting quality of life. These findings suggested the need for further investigation on hormonal alterations, which may be a promising target on BMS management.

Published: August 2024

SummaryIn bipolar disorders, abnormalities of sleep patterns and of circadian rhythms of activity are observed during mood episodes, but also persist during euthymia. Shared vulnerabilities between mood disorders and abnormalities of sleep patterns and circadian rhythms of activity have been suggested. This exploratory study investigated the association between polygenic risk scores for bipolar disorder and major depressive disorder, actigraphy estimates of sleep patterns, and circadian rhythms of activity in a sample of 62 euthymic individuals with bipolar disorder. The polygenic risk score – bipolar disorder and polygenic risk score – major depressive disorder were calculated for three stringent thresholds of significance. Data reduction was applied to aggregate actigraphy measures into dimensions using principal component analysis. A higher polygenic risk score – major depressive disorder was associated with more fragmented sleep, while a higher polygenic risk score – bipolar disorder was associated with a later peak of circadian rhythms of activity. These results remained significant after adjustment for age, sex, bipolar disorder subtype, body mass index, current depressive symptoms, current tobacco use, and medications prescribed at inclusion, but not after correction for multiple testing. In conclusion, the genetic vulnerabilities to major depression and to bipolar disorder might be associated with different abnormalities of sleep patterns and circadian rhythms of activity. The results should be replicated in larger and independent samples.
Indication‐based and patient‐based hand hygiene performance among nurses working at a university hospital
Authors: Shin Bora , Jeong Ihn Sook 
Published: August 2024

AbstractThe traditional method of monitoring hand hygiene (HH) based on specific indications does not ensure that HH is performed for all required indications during patient care. This study aimed to compare HH performance rates (HHPRs) based on specific indications versus overall patient care among nurses at a university hospital. The study retrospectively analyzed HH monitoring data for 1398 indications from 543 patients and 190 nurses. Observations were conducted continuously, tracking a single healthcare worker from before patient contact until the end of the contact within a 30‐min period. The indication‐based HHPR was found to be 89.1%, while the patient‐based HHPR was 78.1%. In the context of patient‐based HHPR, the lowest rates were observed among nurses in the emergency room (48.3%) and those with less than 1 year of work experience (66.7%). Moreover, the largest discrepancy between indication‐based and patient‐based HHPR was noted among emergency room nurses with less than 1 year of experience. This significant difference underscores the need for patient‐based HH monitoring, particularly for nurses in emergency settings and those with limited experience.

AbstractBackgroundThe oral microbiome‐dependent nitrate (NO3−)–nitrite (NO2−)–nitric oxide (NO) pathway may help regulate blood pressure. NO2−‐producing bacteria in subgingival plaque are reduced in relative abundance in patients with untreated periodontitis compared with periodontally healthy patients. In periodontitis patients, the NO2−‐producing bacteria increase several months after periodontal treatment. The early effects of periodontal treatment on NO2−‐producing bacteria and the NO3−–NO2−–NO pathway remain unknown. The aim of this study was to determine how periodontal treatment affects the oral NO2−‐producing microbiome and salivary NO3− and NO2− levels over time.MethodsThe subgingival microbiota of 38 periodontitis patients was analysed before (baseline [BL]) and 1, 7 and 90 days after periodontal treatment. Changes in NO2−‐producing bacteria and periodontitis‐associated bacteria were determined by 16s rRNA Illumina sequencing. Saliva samples were collected at all‐time points to determine NO3− and NO2− levels using gas‐phase chemiluminescence.ResultsA significant increase was observed in the relative abundance of NO2−‐producing species between BL and all subsequent timepoints (all p < 0.001). Periodontitis‐associated species decreased at all timepoints, relative to BL (all p < 0.02). NO2−‐producing species negatively correlated with periodontitis‐associated species at all timepoints, with this relationship strongest 90 days post‐treatment (ρ = −0.792, p < 0.001). Despite these findings, no significant changes were found in salivary NO3− and NO2− over time (all p > 0.05).ConclusionsPeriodontal treatment induced an immediate increase in the relative abundance of health‐associated NO2−‐producing bacteria. This increase persisted throughout periodontal healing. Future studies should test the effect of periodontal treatment combined with NO3− intake on periodontal and cardiovascular health.

Published: August 2024

AbstractImmunoglobulin A (IgA) vasculitis, or Henoch‐Schonlein purpura, is the most common systemic vasculitis in children, clinically presenting as palpable purpura in combination with arthritis, gastrointestinal involvement, or kidney injury. Subcutaneous edema is reported in patients with IgA vasculitis, and it commonly affects the lower extremities, especially around joints. Here, we report a case of IgA vasculitis with a rare presentation of edema isolated to the periorbital area in a 7‐year‐old boy, who subsequently developed crescentic glomerulonephritis with nephrotic range proteinuria. Isolated periorbital edema is an uncommon cutaneous feature of IgA vasculitis.

AbstractThe whitefly, a polyphagous insect pest feeding on nearly 1328 plant species, is a major threat to global cotton production and incurs up to 50% yield losses in cotton production in Pakistan. We investigated whether increased aspartate in phloem sap imparts whitefly toxicity and protects cotton plants from intense damage. The enzymatic step for aspartate production is carried through aspartate aminotransferase (AAT). In this study, we constitutively overexpressed the Oryza sativa cytoplasmic AAT (OsAAT2) under the CaMV35S promoter in Gossypium hirsutum cv. CIM‐482. Real‐time PCR analysis of the AAT transcripts revealed a 2.85‐ to 31.7‐fold increase in mRNA levels between the different cotton lines. A substantial increase in the free‐amino acid content of the major N‐assimilation and transport amino acids (aspartate, glutamate, asparagine, and glutamine) was seen in the phloem sap of the transgenic cotton lines. The bioassay revealed that the two transgenic cotton lines with the highest free aspartate content in the phloem sap exhibited 97 and 94% mortality in the adult whitefly population and a 98 and 96% decline in subsequent nymph populations, respectively. There was also a significant change in the physiological behaviour of the transgenic cotton lines, with an increased net assimilation (A), gaseous exchange (Gs) and rate of transpiration (E). Improved morphological characteristics like plant height, total number of bolls and fiber yield were recorded in transgenic cotton lines. The AAT gene shows promise in mitigating whitefly infestations and enhancing the overall health and yield of cotton plants.
