A Systematic Review of Antidepressants and Psychotherapy Commonly Used in the Treatment of Late Life Depression for Their Effects on Cognition.

Cognitive dysfunction is common in late life depression (LLD) and is a major risk factor for dementia. Recent studies show limited improvement in cognition with commonly employed treatments for LLD, contradicting the notion that cognition "returns to normal" with treatment. However, findings differ with the treatments used. The aim of this study is to perform a systematic review of studies of antidepressants and psychotherapies commonly employed in LLD to determine their effects on cognition, particularly processing speed, memory, and executive function. We searched for trials of acute phase treatment, in nondemented individuals 60 years and older with unipolar nonpsychotic Major Depressive Disorder, that assessed cognitive performance with neuropsychological tests before and after treatment. We compared the magnitude of change in cognition by examining within group effect sizes. Six antidepressant trials and two psychotherapy trials (both using Problem Solving Therapy)(PST) provided relatively comparable data that allowed for quantitative comparison. Nine other antidepressant trials provided descriptive findings. Sertraline and vortioxetine had significant positive effects on processing speed and memory. Duloxetine had significant effects on memory. The most selective SRIs-citalopram and escitalopram-had minimal effects on cognition and citalopram had adverse effects in depression nonresponders. PST had modest effects on processing speed and no effect on memory. Effects of practice and improvement in depression on cognition are examined. In all but one study, cognition was a secondary outcome and various quality indicators (e.g. blinding cognitive assessment to treatment) were often not reported. As a consequence, these findings must be considered preliminary.

Exploring the late maturation of an intrinsic episodic memory network: A resting-state fMRI study.

Previous research suggests that episodic memory relies on functional neural networks,which are present even in the absence of an explicit task. The regions that integrate.these networks and the developmental changes in intrinsic functional connectivity.remain elusive. In the present study, we outlined an intrinsic episodic memory network.(iEMN) based on a systematic selection of functional connectivity studies, and.inspected network differences in resting-state fMRI between adolescents (13-17 years.old) and adults (23-27 years old) from the publicly available NKI-Rockland Sample.Through a review of brain regions commonly associated with episodic memory.networks, we identified a potential iEMN composed by 14 bilateral ROIs, distributed.across temporal, frontal and parietal lobes. Within this network, we found an increase.in resting-state connectivity from adolescents to adults between the right temporal pole.and two regions in the right lateral prefrontal cortex. We argue that the coordination of.these brain regions, connecting areas of semantic processing and areas of controlled.retrieval, arises as an important feature towards the full maturation of the episodic.memory system. The findings add to evidence suggesting that adolescence is a key.period in memory development and highlights the role of intrinsic functional.connectivity in such development.

Neurophysiological measures of covert semantic processing in neurotypical adolescents actively ignoring spoken sentence inputs: A high-density event-related potential (ERP) study.

Language comprehension requires semantic processing of individual words and their context within a sentence. Well-characterized event-related potential (ERP) components (the N400 and late positivity component (LPC/P600)) provide neuromarkers of semantic processing, and are robustly evoked when semantic errors are introduced into sentences. These measures are useful for evaluating semantic processing in clinical populations, but it is not known whether they can be evoked in more severe neurodevelopmental disorders where explicit attention to the sentence inputs cannot be objectively assessed (i.e., when sentences are passively listened to). We evaluated whether N400 and LPC/P600 could be detected in adolescents who were explicitly ignoring sentence inputs. Specifically, it was asked whether explicit attention to spoken inputs was required for semantic processing, or if a degree of automatic processing occurs when the focus of attention is directed elsewhere? High-density ERPs were acquired from twenty-two adolescents (12-17 years), under two experimental conditions: 1. individuals actively determined whether the final word in a sentence was congruent or incongruent with sentence context, or 2. passively listened to background sentences while watching a video. When sentences were ignored, N400 and LPC/P600 were robustly evoked to semantic errors, albeit with reduced amplitudes and protracted/delayed latencies. Statistically distinct topographic distributions during passive versus active paradigms pointed to distinct generator configurations for semantic processing as a function of attention. Covert semantic processing continues in neurotypical adolescents when explicit attention is withdrawn from sentence inputs. As such, this approach could be used to objectively investigate semantic processing in populations with communication deficits.

Early hospital discharge after cesarean delivery: a systematic review and meta-analysis of randomized controlled trials.

OBJECTIVE: The aim of this systematic review and meta-analysis was to assess whether earlier discharge from hospital after cesarean delivery (CD) affects the rate of maternal readmission. DATA SOURCE: The research was conducted using PubMed, Embase, Web of Sciences, Scopus, ClinicalTrials.gov and the Cochrane Central Register of Controlled Trials as electronic databases, from the inception of each database to August 2023 with RCT as publication type. No restrictions for language or geographic location were applied. STUDY ELIGIBILITY CRITERIA: Selection criteria included only RCTs comparing the effect of earlier vs later hospital discharge after CD. STUDY APPRAISAL AND SYNTHESIS METHODS: The primary outcome was the rate of maternal readmission. The summary measures were reported as relative risk (RR) or as mean difference (MD) with 95% confidence intervals (CI) using the random effects model of Mentel-Haenszel. I-squared (Higgins I2) greater than 0% was used to identify heterogeneity. "Earlier" and "later" hospital discharge was first considered according to each study's definition and then a subgroup analysis was performed including only studies defining as "earlier" a discharge within 24-28 hours and "later" a discharge at 48 hours after CD. The study was registered on PROSPERO (CRD 42024529885). RESULTS: Seven RCTs including 4,267 individuals, of which 2,125 (49.8%) randomized in the early discharge and 2,142 (50.2%) in the late discharge group were included. There was no difference between the two groups in the rate of maternal readmission (3.6% vs 3.4%, RR 1.10; 95% CI 0.80-1.52). There was no significant difference in both maternal complications diagnosed within 6 weeks after CD and neonatal complications. Early discharge after CD was associated with improved psychological wellbeing and was cost-effective. The subgroup analysis of the primary outcomes only in high-quality studies showed similar results: no difference in the rate of maternal readmission was observed (3.8% vs 3.2%, RR 1.20; 95% CI 0.63-2.30) between the two groups. When focusing only on studies comparing 24-28-hour vs 48-hour hospital discharge, the rate of maternal readmission did not differ between the two groups, while the rates of neonatal readmission and neonatal jaundice were significantly higher in the earlier discharge group. CONCLUSIONS: There is no increase in the rate of maternal readmission following early hospital discharge at 24-28 hours as opposed to later hospital discharge after a CD. The rates of neonatal readmission and neonatal jaundice were significantly higher in the earlier discharge group. Patients undergoing uncomplicated CDs might be discharged from the hospital at 24-28 hours postpartum, as long as close neonatal outpatient follow-up is done in 1-2 days; if this is unfeasible, discharge at 48 hours seems to be safe and effective for both mother and baby. Early discharge after CD was associated with improved psychological wellbeing and was cost-effective.

Case report: Two siblings with very late onset of holocarboxylase synthase deficiency and a mini-review.

Holocarboxylase synthase (HCS) deficiency is an extremely rare metabolic disorder typically presenting as severe neonatal metabolic acidosis, lethargy, hypotonia, vomiting, and seizures. This report describes two siblings in a family with late-onset forms of HCS deficiency. The younger sister presented at the age of 11 years and manifested as acute metabolic acidosis, which promptly resolved following rehydration and biotin administration. The results of the organic urine profile confirmed multiple carboxylase deficiency, and genetic testing revealed a novel pathogenic variant in the HLCS gene (NM_000411.8) in the homozygous state: c.995A>G; p. (Gln332Arg). No further decompensation was observed for her during the 3-year follow-up period. His older brother was diagnosed at the age of 23 years-old through biochemical tests, without any history of acidotic decompensation. A mini-review of HCS deficiency with late onset (>1 year) or early onset (<1 month) revealed that splice variants are associated with late onset, while both variants p. (Leu216Arg) and p. (Leu237Pro) are associated with early onset. However, the majority of genotypes do not show a clear correlation with the timing of HCS deficiency onset. The most significant point here is the description of extremely late-onset cases of HCS deficiency. This can prompt metabolic investigations and raise suspicion of this rare disease in cases of unexplained metabolic acidosis, even beyond early childhood.

A Resected Case of Simultaneous Gastric and Multiple Pancreatic Metastases of Renal Cell Carcinoma 11 Years After Nephrectomy.

A 50-year-old man with a history of nephrectomy for renal cell carcinoma (RCC) 11 years prior was diagnosed with gastric and multiple pancreatic metastases of RCC. He underwent a pyloric gastrectomy and total pancreatic resection. RCC metastases to the pancreas are rare, and gastric metastases are even rarer. This case represents a rare instance of simultaneous RCC metastases to both the stomach and pancreas. Although there is no difference in prognosis between solitary and multiple pancreatic metastases, surgical resection is recommended even for multiple lesions. However, preoperative imaging often fails to identify all pancreatic metastatic lesions, making total pancreatectomy a consideration for ensuring complete resection, especially when preoperative detection is challenging.

Relationship between radiation dose and cerebral microbleed formation in dogs with intracranial tumors.

BACKGROUND: Cerebral microbleeds (CMBs) are a possible sequela in human brain tumor patients treated with radiation therapy (RT). No such association is reported in dogs. OBJECTIVES: To investigate whether CMBs occur in dogs after radiotherapy, and if there is an association between number and dose, and an increase over time. ANIMALS: Thirty-four client-owned dogs irradiated for primary intracranial neoplasia. ≥2 magnetic resonance imaging (MRI) scans including susceptibility-weighted imaging (SWI) were required. METHODS: Retrospective, observational, single-center study. Cerebral microbleeds identified on 3 T SWI were counted within the entire brain, and within low- (<20 Gy), intermediate- (20-30 Gy), and high- (>30 Gy) dose regions. A generalized linear mixed-effects model was used to analyze the relationship between the CMBs count and the predictor variables (irradiation dose, time after treatment). RESULTS: Median follow-up time was 12.6 months (range, 1.8-37.6 months). Eighty-three MR scans were performed. In 4/15 dogs (27%, 95% CI, 10%-52%) CMBs were present at baseline. ≥1 CMBs after RT were identified in 21/34 dogs (62%, 95% CI, 45%-77%). With each month, the number of CMBs increased by 14% (95% CI, 11%-16%; P < .001). The odds of developing CMBs in the high-dose region are 4.7 times (95% CI, 3.9-5.6; P < .001) greater compared with the low-dose region. CONCLUSION AND CLINICAL IMPORTANCE: RT is 1 possible cause of CMBs formation in dogs. Cerebral microbleeds are most likely to occur in the peritumoral high-dose volume, to be chronic, and to increase in number over time. Their clinical relevance remains unknown.

Flavonoid-Rich Fruit Intake in Midlife and Late-Life and Associations with Risk of Dementia: The Framingham Heart Study.

BACKGROUND: Fruits are an important source of flavonoids, and greater intake of dietary flavonoids in older adults has been shown to be associated with decreased risk of dementia. It is unclear whether this relationship is similar or different between younger adults and older adults. OBJECTIVES: We examined for associations between midlife and late-life intake of flavonoid-rich fruits and incident dementia. We hypothesized that greater total cumulative intake of flavonoid-rich fruits in midlife and late-life adults would be associated with reduced risk of all-cause dementia. DESIGN: Longitudinal, cohort study design. SETTING: Framingham Heart Study, which is a longitudinal, multi-generational community-based cohort based in Framingham, Massachusetts, USA. PARTICIPANTS: Participants from the Framingham Heart Study Offspring cohort were included (n = 2,790) who attended the fifth core exam between 1991 to 1995, and were dementia-free and at least 45 years of age at that time, as well as had valid food frequency questionnaires from the fifth to ninth core exams. MEASUREMENTS: Consumption of fruits with high flavonoid content or are important contributors to overall flavonoid intake was collected via food frequency questionnaire. Flavonoid-rich fruits from the food frequency questionnaire included raisins or grapes, prunes, bananas, fresh apples or pears, apple juice or cider, oranges, orange juice, grapefruit, grapefruit juice, strawberries, blueberries, and peaches, apricots, or plums. Dementia ascertainment was based on a multidisciplinary consensus committee, and included all-cause dementia and Alzheimer's disease dementia diagnoses based on research criteria. Cox models were used to examine associations between cumulative fruit intake and incident dementia, stratified by midlife (45-59 years; n = 1,642) and late-life (60-82 years; n = 1,148). RESULTS: Greater cumulative total fruit intake in midlife, but not late-life, was significantly associated with a 44% decreased risk of all-cause dementia (HR = 0.56; 95% CI = 0.32 - 0.98; p = 0.044). Decreased risk of all-cause dementia was also associated with higher intake of apples or pears in midlife and late-life, as well as higher intake of raisins or grapes in midlife only, and higher intake of oranges, grapefruit, blueberries, and peaches, apricots, or plums in late-life only. CONCLUSIONS: Among participants from the Framingham Heart Study, greater overall consumption of flavonoid-rich fruits in midlife was associated with reduced risk of dementia, though intake of specific fruits in midlife and late-life may have a protective role against developing dementia. These findings may help to inform future recommendations on when dietary interventions may be most beneficial to healthy brain aging across the life course.

Integrating and Dividing in a Late Bronze Age Society: Internal Organization of Settlements of the Tisza Site Group in the Southern Carpathian Basin, 1600-1200 b.c.

Recent research in the later Bronze Age of the southern Carpathian Basin has revealed an extensive network of large, often-enclosed settlements. Within this network, a particularly dense group of sites has recently been characterized: the Tisza Site Group (TSG). Building on advances in inter-site relations in recent research, we explore social organization within settlements using five case studies from different parts of this network. Using a multi-proxy approach of satellite imagery, systematic surface survey, and geophysical prospection, we studied the distribution of archaeological features and surface traces of activity within the enclosed space. Results indicate that sites in the TSG shared a common ethos regarding the use of space and the role of the built environment that was specific to LBA occupation of this landscape. Activity areas with domestic assemblages distributed in low-density relative to the enclosed space indicates settlement and specialist subsistence activities took place in parallel.

Severe Epilepsy in an Individual With a TSC2 R905Q Variant Prompting Late Diagnosis in Affected Family Members.

BACKGROUND: Tuberous sclerosis complex (TSC) is a multisystemic disorder caused by inactivating variants in the mTOR pathway inhibitor genes TSC1 and TSC2. Individuals with TSC are predisposed to benign tumors in multiple organs as well as TSC-associated neuropsychiatric disorders (TAND) and epilepsy. Pathogenic variants in TSC2 are typically associated with a more severe phenotype compared with TSC1; the TSC2 R905Q variant has been shown to be an exception, where patients have been reported to present with unusually mild TSC features that may be undetected. METHODS: We studied the TSC phenotype of a 13-year-old individual and three family members with a TSC2 c.2714G>A (R905Q) pathogenic variant. RESULTS: Patient 1 presented with severe medically refractory epilepsy without tubers or subependymal nodules and only mild dermatologic features of TSC missed on virtual examinations. Her mother and maternal aunt (Patients 2 and 3-diagnosed after age 50 years) presented with a mild phenotype, with dermatologic features and TAND. Her maternal uncle (Patient 4-diagnosed at age 47 years) displayed the most severe phenotype, presenting with intellectual disability, medically refractory epilepsy, obsessive-compulsive disorder, post-traumatic stress disorder, and psychosis. CONCLUSIONS: This study expands the possible phenotypic spectrum of TSC2 R905Q variant, demonstrating an association with severe epilepsy without associated neuroradiological stigmata. This presentation highlights the possibility of occult focal cortical dysplasia in TSC and emphasizes the importance of genetic testing in individuals with severe epilepsy. Moreover, a late adult diagnosis was subsequently made in other family members allowing for appropriate TSC surveillance to occur.

Neuropsychological Late Effects and Quality-of-Life Outcomes in Pediatric Brain Tumor Survivors: Role of Pediatric Neurologists in Monitoring and Management.

Pediatric brain tumor (PBT) survivors are at significantly increased risk of cognitive, psychosocial, and educational/vocational sequelae that impact health-related quality of life. These complications and health morbidities result in high burden on survivors and their families, particularly those already vulnerable to disparities in health care access and outcomes. Since neurological comorbidities are common in this population, neurologists are uniquely positioned to screen, treat identified symptoms, and connect families with services and resources. A tiered assessment approach can facilitate early identification of concerns and reduce barriers to care. We review common presenting conditions, highlight risk factors, and provide screening tools and recommendations to facilitate comprehensive survivorship care for PBT survivors.

Late gadolinium enhancement and outcome of cardiac resynchronization therapy in non-ischemic cardiomyopathy.

BACKGROUND: It is uncertain whether CRT with defibrillator (CRTD) is superior to CRT with pacemaker (CRTP) in NICM. Patients with low arrhythmic risk and high probability of response to CRT might be ideal candidates for CRTP. We aimed to evaluate predictors of ventricular arrhythmias and of echocardiographic response to cardiac resynchronization therapy (CRT) in non-ischemic cardiomyopathy (NICM). METHODS: Multicenter, retrospective observational study of NICM patients with left ventricular ejection fraction (LVEF) ≤35 %, cardiac magnetic resonance with analysis of late gadolinium enhancement (LGE) available and de-novo CRT implant. Echocardiographic response to CRT was defined as an improvement in LVEF ≥10 %. The combined arrhythmic endpoint included sustained ventricular tachycardia, appropriate ICD therapy, resuscitated cardiac arrest and sudden death. RESULTS: We included 167 patients, with a median follow-up of 63 months. LGE was present in 77 (46 %). Response to CRT occurred in 68 % of patients, more frequently in LGE- than in LGE+ (81 % vs 53 %, p < 0.001). Absence of LGE (OR 3.4, p = 0.002), was an independent predictor of response to CRT. The arrhythmic endpoint occurred in 19 patients (11 %). Among LGE- patients there were zero arrhythmic events as compared to a 25 % cumulative incidence in LGE+ (p < 0.001). Presence of LGE (HR 22.5, p < 0.001), was an independent predictor of the arrhythmic endpoint. CONCLUSION: Absence of LGE identifies patients at minimal arrhythmic risk and with high probability of response to CRT. Thus, they might be ideal candidates to CRT-P.

Prediction model for early diagnosis of late-onset sepsis in preterm newborns.

AIM: Late-onset neonatal sepsis has a high mortality rate in premature infants. To date, no single test in the evaluation of neonatal sepsis has been demonstrated to be both sensitive and specific enough to assist in timely decision making. The aim of our study is to develop a predictive model that can be applied to all premature babies, using clinical and laboratory findings in premature babies, to recognize late-onset neonatal sepsis. STUDY DESIGN: 65 premature patients diagnosed with culture-proven late-onset neonatal sepsis and hospitalized in Dr. Behcet Uz Pediatric Diseases and Surgery Training and Research Hospital neonatal intensive care unit between January 2018 and December 2020, and 65 premature newborns of similar age and gender who did not have sepsis were included in the study retrospectively. RESULTS: In our study, feeding difficulties, worsening in clinical appearance and fever were found to be significant among clinical findings, while thrombocytopenia and high C-reactive protein among laboratory findings are the strongest data supporting late-onset neonatal sepsis. In multiple regression analysis, thrombocytopenia, mean platelet volume, C-reactive protein, lymphocyte count and feeding difficulties had the highest odds ratio (p <  0.05). By converting these data into a scoring system, a nomogram was created that can be easily used by all clinicians. CONCLUSION: In our study, we developed a scoring system that can be easily applied to all premature patients by evaluating the clinical and laboratory findings in late-onset neonatal sepsis. We think that it will help in recognizing late-onset neonatal sepsis and strengthening the treatment decision. Predicting the individual probability of sepsis in preterm newborns may provide benefits for uninfected newborns to be exposed to less antibiotics, not to be separated from mother and baby, and to reduce healthcare system expenditures. The nomogram can be used to assess the likelihood of sepsis and guide treatment decision.

Significance of early diagnosis and treatment of adult late-onset Pompe disease on the effectiveness of enzyme replacement therapy in improving muscle strength and respiratory function: a case report.

BACKGROUND: Pompe disease, a rare autosomal recessive disorder, is caused by mutations in the acid α-glucosidase gene. Pompe disease is a congenital metabolic disorder that affects all organs, particularly the striated muscle and nerve cells. Diagnosis is typically confirmed through enzyme assays that reveal reduced acid α-glucosidase activity. Enzyme replacement therapy utilizing human α-glucosidase is an available treatment option. Timely diagnosis and treatment in the early stages of the disease significantly impact the effectiveness of enzyme replacement therapy in enhancing patient condition. Here, we present a case of a patient with Pompe disease diagnosed 20 years after the onset of clinical symptoms. CASE PRESENTATION: A 38-year-old Iranian Baloch woman referred to our rheumatology clinic with progressive muscle weakness presents with a complex medical history. On mechanical ventilation for 12 years, she has endured fatigue and limb weakness since the age of 16, exacerbated following an abortion at 19. Despite undergoing corticosteroid and azathioprine therapies, the suspected diagnosis of inflammatory myopathy did not yield improvement. Hospitalization at 23 due to respiratory failure post-pregnancy led to her continued reliance on a ventilator. A dried blood spot test indicated reduced GAA enzyme activity, confirming a diagnosis of Pompe disease through genetic testing. Treatment with myozyme for 2 years demonstrated limited efficacy, as the patient experienced improved breathing but no significant overall improvement in limb-girdle muscular weakness. This case underscores the challenges and complexities involved in diagnosing and managing rare neuromuscular disorders like Pompe disease. CONCLUSION: Early intervention with enzyme replacement therapy plays a crucial role in halting further muscle loss and disease progression in Pompe disease patients. It is important to note that treatment during advanced stages of the disease may not yield substantial benefits. Nevertheless, enzyme instability and denaturation due to temperature and neutral pH levels, along with limited delivery to disease-relevant tissues, can pose challenges in treatment. However, timely diagnosis of Pompe disease is paramount for its effective management and improved outcomes.

Unusual presentation of PYGM gene mutation as late-onset McArdle disease with camptocormia: a case report.

BACKGROUND: Glycogen storage disease type 5 (McArdle disease) leads to a deficiency in the activity of myophosphorylase resulting in an impaired glucose utilization. The disease can be caused by a variety of mutations in the PYGM gene, and its typical clinical manifestation is muscles weakness within the first three decades of life. CASE PRESENTATION: In this case report we present the diagnostic work-up of a physically active 78-year-old Caucasian patient suffering from a 2-year history of progressive camptocormia including clinical, radiologic, histological, and genetic tests. There was no history of neuro-muscular diseases in the family. Serum CK levels were moderately increased while other blood/urine parameters were normal. Magnetic resonance imaging showed fatty remodeling of the muscles of the back. Histochemical examination of a muscle biopsy revealed the absence of myophosphorylase activity, while gene analysis identified a known early-onset McArdle mutation in the PYGM gene. CONCLUSION: This case highlights that the clinical spectrum of PYGM gene mutation typically manifest during adolescence, but it is also a differential diagnosis in late onset muscle disorders and emphases the investigation of the role of ACE inhibitors in this disease.

Alasemenia, the earliest ovule with three wings and without cupule.

The ovules or seeds (fertilized ovules) with wings are widespread and especially important for wind dispersal. However, the earliest ovules in the Famennian of the Late Devonian are rarely known about the dispersal syndrome and usually surrounded by a cupule. From Xinhang, Anhui, China, we now report a new taxon of Famennian ovules, Alasemenia tria gen. et sp. nov. Each ovule of this taxon possesses three integumentary wings evidently extending outwards, folding inwards along abaxial side and enclosing most part of nucellus. The ovule is borne terminally on smooth dichotomous branches and lacks a cupule. Alasemenia suggests that the integuments of the earliest ovules without a cupule evolved functions in probable photosynthetic nutrition and wind dispersal. It indicates that the seed wing originated earlier than other wind dispersal mechanisms such as seed plume and pappus, and that three- or four-winged seeds were followed by seeds with less wings. Mathematical analysis shows that three-winged seeds are more adapted to wind dispersal than seeds with one, two or four wings under the same condition.

Many plants need seeds to reproduce. Seeds come in all shapes and sizes and often have extra features that help them disperse in the environment. For example, some seeds develop wings from seed coat as an outer layer, similar to fruits of sycamore trees that have two wings to help them glide in the wind. The first seeds are thought to have evolved around 372-359 million years ago in a period known as the Famennian (belonging to the Late Devonian). Fossil records indicate that almost all these seeds were surrounded by an additional protective structure known as the cupule and did not have wings. To date, only two groups of Famennian seeds have been reported to bear wings or wing-like structures, and one of these groups did not have cupules. These Famennian seeds all had four wings. Wang et al. examined fossils of seed plants collected in Anhui province, China, which date to the Famennian period. The team identified a new group of seed plants named the Alasemenia genus. The seeds of these plants each had three wings but no cupules. The seeds formed on branches that did not have any leaves, which indicates the seeds may have performed photosynthesis (the process by which plants generate energy from sunlight). Mathematical modelling suggested that these three-winged seeds were better adapted to being dispersed by the wind than other seeds with one, two or four wings. These findings suggest that during the Famennian the outer layer of some seeds that lacked cupules evolved wings to help the seeds disperse in the wind. It also indicates that seeds with four or three wings evolved first, followed by other groups of seed plants with fewer seed wings. Future studies may find more winged seeds and further our understanding of their evolutionary roles in the early history of seed plants.

Unveiling trends in late diagnosis among 22,504 people living with HIV in Hunan, China.

This study examined the prevalence of HIV late diagnosis (LD) and identified associated factors with LD among people living with HIV (PLWH). We extracted sociodemographic, epidemiological, and immunological information between 2018 and 2021 in Hunan, China from the HIV/AIDS Comprehensive Response Information Management System of China. The chi-squared test and multivariable logistic regression model were used to identify the factors associated with LD. Among 22,504 PLWH, 14,988 (66.6%) were diagnosed late. PLWH aged 50 and older had a higher proportion of LD (71.2%) than the younger group (60.0%). Older age, being male, Han ethnicity, being registered in Western Hunan, being transferred from health facilities, and being infected through heterosexual intercourse were associated with LD. Among PLWH younger than 50 years, apart from the factors mentioned above, individuals who had primary school or lower education, were non-student, and were divorced or widowed were more likely to be diagnosed late. Unlike younger PLWH, these factors were not associated with LD in the older group. But regional disparities in LD were more significant among them. LD in PLWH remains a severe issue, especially among older people. The study findings provided valuable insights into designing programs targeting groups at higher risk of LD to reduce its prevalence.

Self-rated health is an independent predictor of subsequent late mortality after blood or marrow transplantation: A Blood or Marrow Transplant Survivor Study report.

BACKGROUND: The prevalence of suboptimal self-rated health (SRH) and its association with subsequent all-cause and cause-specific mortality after blood or marrow transplantation (BMT) were examined. METHODS: Study participants were drawn from the multicenter Blood or Marrow Transplant Survivor Study, and included patients who were transplanted between 1974 and 2014 and had survived ≥2 years after BMT. Participants (aged ≥18 years) completed a survey at a median of 9 years from BMT, and were followed for a median of 5.6 years after survey completion. Survivors provided information on sociodemographic factors, chronic health conditions, health behaviors, and SRH (a single-item measure rated as excellent, very good, good, fair, or poor; excellent, very good, and good SRH were classified as good SRH, and fair and poor were classified as suboptimal SRH). The National Death Index Plus and Accurint databases and medical records provided vital status through December 2021. RESULTS: Of 3739 participants, 784 died after survey completion (21%). Overall, 879 BMT survivors (23.5%) reported suboptimal SRH. Pain, low socioeconomic status, psychological distress, lack of exercise, severe/life-threatening chronic health conditions, post-BMT relapse, obesity, smoking, and male sex were associated with suboptimal SRH. BMT survivors who reported suboptimal SRH had a 1.9-fold increased risk of all-cause mortality (95% confidence interval [CI], 1.6-2.3), 1.8-fold increased risk of recurrence-related mortality (95% CI, 1.4-2.5), and 1.9-fold increased risk of non-recurrence-related mortality (95% CI, 1.4-2.4) compared to those who reported good SRH. CONCLUSIONS: This single-item measure could help identify vulnerable subpopulations who could benefit from interventions to mitigate the risk for subsequent mortality.

Oral Hygiene Study in Late Adolescence.

The objective of this study is to determine prevalent behaviors and knowledge of oral hygiene on the late adolescents. Only individuals in the late stage of adolescence, specifically between the ages of 18 and 24, that were students from the "Ovidius" University of Constanta were chosen. The involvement was optional. A printed questionnaire was provided for them to complete. A total of 50 participants took part in this study, consisting of 26% (n=13) males and 74% (n=37) females. When asked about their toothbrush preference, 50% (n=25) individuals indicated using just manual toothbrushes. Out of all individuals who have utilized orthodontic appliances, 70.8% (n=17) reported that the dentist recommended for them to receive professional dental hygiene care while undergoing treatment. 78.0% (n=39) individuals reported participating in oral hygiene meetings and would be interested for additional information regarding the topic. It is essential to provide youngsters with early instruction about the importance of oral hygiene in order to develop long-lasting healthy habits.

Usefulness of tissue tracking to differentiate tachycardia-induced cardiomyopathy from dilated cardiomyopathy in patients admitted for heart failure.

INTRODUCTION: Differentiation of tachycardia-induced cardiomyopathy (TIC) from dilated cardiomyopathy (DCM) in patients admitted for heart failure (HF) with left ventricular dysfunction and supraventricular tachyarrhythmia (SVT) remains challenging. The role of tissue tracking (TT) in this setting remains unknown. METHODS: Forty-three consecutive patients admitted for HF due to SVT with left ventricular ejection fraction (LVEF) < 50% undergoing CMR were retrospectively included. Those eventually evolving to LVEF > 50% at follow-up were classified as TIC and those maintaining a LVEF < 50% were classified as DCM. Clinical, echocardiography, and CMR findings, including TT, were analyzed to predict LVEF recovery. RESULTS: Twenty-five (58%) patients were classified as TIC. Late gadolinium enhancement (LGE) was more frequent in DCM group (61% vs 16%, p = 0.004). Left ventricle (LV) peak systolic radial velocity and peak diastolic radial strain rate were lower in DCM group (7.24 ± 4.44 mm/s vs 10.8 ± 4.5 mm/s; p = 0.015 and -0.12 ± 0.33 1/s vs -0.48 ± 0.51 1/s; p = 0.016, respectively). Right ventricle (RV) peak circumferential displacement was lower in patients with TIC (0.2 ± 1.3 vs 1.3 ± 0.9°; p = 0.009). In the multivariate analysis, diabetes (p = 0.046), presence of LGE (p = 0.028), LV peak systolic radial velocity < 7.5 mm/s (p = 0.034), and RV peak circumferential displacement > 0.5° (p = 0.028) were independent predictors of lack of LVEF recovery. CONCLUSION: In the setting of acute HF with LV dysfunction related to SVT, diabetes, LGE, LV peak systolic velocity, and RV peak circumferential displacement are independent predictors of lack of LVEF recovery and, therefore, represent clinically useful parameters to differentiate TIC from DCM.
