Background: Amyotrophic Lateral Sclerosis (ALS) leads to progressive functional decline and reduced survival. Identifying clinical predictors like ALSFRS-R and FVC is essential for prognosis and disease management. Understanding progression profiles based on diagnostic characteristics supports clinical trial design and assessment of treatment response. This study evaluates disease progression and survival predictors in ALS patients from the CNDR. Methods: 1565 ALS patients in the CNDR were analyzed to assess baseline ALSFRS-R, FVC, time from symptom onset to diagnosis, and their association with disease progression and survival. Results: At diagnosis, ALSFRS-R was 44.7 (SD = 5.46), with 72.3% scoring ≥44. Mean FVC was 84.2% (SD = 23.3), with 78.3% of patients having FVC ≥65%. ALSFRS-R declined at 1.06 points/month (SD = 1.33), with faster progression in patients diagnosed within 24 months (1.61 points/month). Patients with ALSFRS-R ≥44 had a median survival of 41.8 months, compared to 30.9 months for those <44 (p < 0.001). Similarly, FVC ≥65% was associated with longer survival (35.4 vs. 29.5 months, p = 0.002). Conclusions: ALSFRS-R and FVC at diagnosis predict survival and inform clinical decision-making. These findings highlight the importance of early diagnosis and targeted interventions to slow disease progression and improve patient outcomes.
Integrating trees and shrubs into agroecosystems increases soil nutrients and organic matter, which helps in the recovery of degraded tropical soils. However, selecting the most appropriate tree and shrub species as sources of nutrients and organic matter requires knowledge of their productive potential. The study aimed to evaluate litter productivity and nutrient input to the soil of three tropical silvopastoral fodder bank species. Litter input from Tithonia diversifolia, Leucaena leucocephala, and Moringa oleifera was quantified monthly for one year. We found that the litterfall amount was greatest (p < 0.05) from T. diversifolia (1.81 t ha–1 yr–1) compared to L. leucocephala (1.26 t ha–1 yr–1) and M. oleifera (118 t ha–1 yr–1). Indeed, T. diversifolia had a greater (p < 0.05) input of biomass from leaves (1.36 t ha–1 yr–1) compared to L. leucocephala (0.901 t ha–1 yr–1) and M. oleifera (0.869 t ha–1 yr–1). The highest biomass input (p < 0.05) occurred in September to the three species, T. diversifolia (0.516 t ha–1), L. leucocephala (0.243 t ha–1), and M. oleifera (0.233 t ha–1), and the lowest biomass input occurred in March. Furthermore, the greatest annual input of carbon (0.687 t ha–1 yr–1), nitrogen (0.030 t ha–1 yr–1), and phosphorus (0.006 t ha–1 yr–1) to the soil originated from T. diversifolia. Our study showed that T. diversifolia had the greatest capacity to produce biomass that potentially can reintroduce nutrients and contribute to the recovery process of degraded soil due to its high litter productivity, besides, a combination of these three species also improves soil nutrients in fodder banks when do not hauling forage for livestock, contributing to sustainability of system.
Early Miocene land mammals from eastern North America are exceedingly rare. Over the past several decades a small, but significant, vertebrate fauna has been recovered by paleontologists and citizen scientists from the Belgrade Formation at the Martin Marietta Belgrade Quarry in eastern North Carolina. This assemblage has 12 land mammal taxa, including beaver (Castoridae), stem lagomorph, carnivorans (Mustelidae, Ailuridae), horses (Equidae), rhinoceros (Rhinocerotidae), tapir (Tapiridae), peccary (Tayassuidae), anthracothere (Anthracotheriidae), entelodont (Entelodontidae), and protoceratid (Protoceratidae). Taken together, the biochronology of this Maysville Local Fauna indicates a late Arikareean (Ar3/Ar4) to early Hemingfordian (He1) North American Land Mammal Age (NALMA). This interval, which includes the Runningwater Chronofauna, documents numerous important Holarctic immigrants, including Amphictis, Craterogale, and cf. Menoceras found at this locality. Strontium isotope stratigraphy (SIS) of shark teeth collected in situ from the Belgrade Formation yield an age of 21.4 ± 0.13 Ma, which validates the age of interbedded land mammals within this unit. It also is consistent with the late Arikareean (Ar3/Ar4) biochronology and Aquitanian Neogene marine stage. New SIS analyses of oysters (Striostrea gigantissima) and clams (Chione) from this mine, previously assigned to late Oligocene or Late Miocene, are significantly older (28.0 ± 0.22 Ma and 27.6 ± 0.26 Ma, respectively) than the land mammals. Depending upon stratigraphic interpretations, these may confirm an older marine facies within the Belgrade Formation. This locality is important because of its marine and terrestrial tie-ins that facilitate intercalibration of both NALMAs and Cenozoic marine stages.
Ochetosoma heterocoelium (Travassos, 1921) was collected from the mouth and oesophagus of a pit viper, Bothrops moojeni Hoge, 1966 in São Sebastião do Paraíso Farm (21°51’48.26" S, 48°26’56.78" W), municipality of Boa Esperança do Sul, São Paulo State, Brazil. In this study, we provide the first molecular characterisation of this digenean using 28S rDNA and COI sequences, and its phylogenetic position within the Plagiorchiida is assessed. Furthermore, new morphological features are added to the diagnosis of the species, and scanning electron microscopy photomicrographs are presented. Sequences of the 28S rRNA gene of O. heterocoelium were successfully obtained and aligned with 35 digenean species belonging to Plagiorchiida. Only three congeners – O. aniarum (Leidy, 1890), O elongatum (Seo et al. 2024), and O. kansense (Crow, 1913) – have been sequenced for this molecular marker. The newly sequenced individuals of O. heterocoelium are 98.7% and 99.4% similar to O. aniarum and O. kansensis, respectively, and Ochetosoma is not recovered as a monophyletic group. Dasymetra nicolli Holl and Allison, 1935 and Lechriorchis tygarti Talbot, 1933 are nested with Ochetosoma.
The description and delineation of trematode species is a major ongoing task. Across the field there has been, and currently still is, great variation in the standard of this work and in the sophistication of the proposal of taxonomic hypotheses. Although most species are relatively unambiguously distinct from their congeners, many are either morphologically very similar, including the major and rapidly growing component of cryptic species, or are highly variable morphologically despite little to no molecular variation for standard DNA markers. Here we review challenges in species delineation in the context provided to us by the historical literature, and the use of morphological, geographical, host, and molecular data. We observe that there are potential challenges associated with all these information sources. As a result, we encourage careful proposal of taxonomic hypotheses with consideration for underlying species concepts and frank acknowledgement of weaknesses or conflict in the data. It seems clear that there is no single source of data that provides a wholly reliable answer to our taxonomic challenges but that nuanced consideration of information from multiple sources (the ‘integrated approach’) provides the best possibility of developing hypotheses that will stand the test of time.
We present a novel scheme for rapid quantitative analysis of debris generated during experiments with solid targets following relativistic laser–plasma interaction at high-power laser facilities. Results are supported by standard analysis techniques. Experimental data indicate that predictions by available modelling for non-mass-limited targets are reasonable, with debris of the order of hundreds of μg per shot. We detect for the first time two clearly distinct types of debris emitted from the same interaction. A fraction of the debris is ejected directionally, following the target normal (rear and interaction side). The directional debris ejection towards the interaction side is larger than on the side of the target rear. The second type of debris is characterized by a more spherically uniform ejection, albeit with a small asymmetry that favours ejection towards the target rear side.
In many species with encapsulated larval development, the larvae play an active role in hatching. However, the factors that control when the larvae hatch from each egg-capsule within an egg-mass are largely unknown. Advanced egg-masses of the gastropod Crepipatella peruviana were used to determine the hatching time of capsules from each egg-mass. After each female was detached, the egg-mass was also removed from the substrate and all capsules were then counted and measured. All capsules were examined to determine the time of hatching and the order in which capsules hatched from each egg-mass. Larvae were collected from each hatched egg-capsule and the number, size and weight of larvae from each capsule were determined. After 50–60% of the capsules from each egg-mass had hatched, the same characteristics of the remaining unhatched larvae from sister capsules were documented. Larvae were found to have hatched when they reached a size of 354 ± 22 μm (n = 245). Larvae from capsules within the same egg-mass hatched over a period of up to 12-days. The order of hatching in capsules from the same egg-mass was determined by larval content: capsules with fewer larvae and smaller capsules with heavier larvae hatched first. The hatching from one capsule in any given egg-mass did not induce the hatching of its sister capsules. Furthermore, hatching also occurred successfully in the mother absence, suggesting that this process is largely or completely controlled by the encapsulated larvae, although a possible maternal role in synchronizing hatching cannot be excluded.
We used the PW high-repetition laser facility VEGA-3 at Centro de Láseres Pulsados in Salamanca, with the goal of studying the generation of radioisotopes using laser-driven proton beams. Various types of targets have been irradiated, including in particular several targets containing boron to generate α-particles through the hydrogen–boron fusion reaction. We have successfully identified γ-ray lines from several radioisotopes created by irradiation using laser-generated α-particles or protons including 43Sc, 44Sc, 48Sc, 7Be, 11C and 18F. We show that radioisotope generation can be used as a diagnostic tool to evaluate α-particle generation in laser-driven proton–boron fusion experiments. We also show the production of 11C radioisotopes, $\approx 6 \times 10^{6}$, and of 44Sc radioisotopes, $\approx 5 \times 10^{4}$ per laser shot. This result can open the way to develop laser-driven radiation sources of radioisotopes for medical applications.
We present a construction of left braces of right nilpotency class at most two based on suitable actions of an abelian group on itself with an invariance condition. This construction allows us to recover the construction of a free right nilpotent one-generated left brace of class two.
Mounting U.S. research suggests many non-White individuals feel solidarity with, and identify as, people of color (PoC). Yet measurement limitations prevent scholars from testing whether these constructs are empirically different. We explain why these concepts diverge and evaluate our claims with an expanded battery of measures across U.S. Asian, Black, Latino, and Multiracial adults (N = 3402). Using multi-group confirmatory factor analysis, we show these items capture related but distinct concepts among PoC (configural invariance). We then establish that these items uniformly measure each construct across PoC groups (metric invariance), with mean level differences validly reflecting actual heterogeneity between groups, rather than measurement artifacts (scalar invariance). Finally, consistent with our conceptualization, we show that solidarity among PoC mediates the association between PoC identification and support for policies that implicate various communities of color. We end with practical advice for using these items in surveys of racially diverse populations.
According to International Union for the Conservation of Nature (IUCN) guidelines, all species must be assessed against all criteria during the Red Listing process. For organismal groups that are diverse and understudied, assessors face considerable challenges in assembling evidence due to difficulty in applying definitions of key terms used in the guidelines. Challenges also arise because of uncertainty in population sizes (Criteria A, C, D) and distributions (Criteria A2/3/4c, B). Lichens, which are often small, difficult to identify, or overlooked during biodiversity inventories, are one such group for which specific difficulties arise in applying Red List criteria. Here, we offer approaches and examples that address challenges in completing Red List assessments for lichens in a rapidly changing arena of data availability and analysis strategies. While assessors still contend with far from perfect information about individual species, we propose practical solutions for completing robust assessments given the currently available knowledge of individual lichen life-histories.
The field of healthcare epidemiology is increasingly focused on identifying, characterizing, and addressing social determinants of health (SDOH) to address inequities in healthcare quality. To identify evidence gaps, we examined recent systematic reviews examining the association of race, ethnicity, and SDOH with inpatient quality measures.
Methods:
We searched Medline via OVID for English language systematic reviews from 2010 to 2022 addressing race, ethnicity, or SDOH domains and inpatient quality measures in adults using specific topic questions. We imported all citations to Covidence (www.covidence.org, Veritas Health Innovation) and removed duplicates. Two blinded reviewers assessed all articles for inclusion in 2 phases: title/abstract, then full-text review. Discrepancies were resolved by a third reviewer.
Results:
Of 472 systematic reviews identified, 39 were included. Of these, 23 examined all-cause mortality; 6 examined 30-day readmission rates; 4 examined length of stay, 4 examined falls, 2 examined surgical site infections (SSIs) and one review examined risk of venous thromboembolism. The most evaluated SDOH measures were sex (n = 9), income and/or employment status (n = 9), age (n = 6), race and ethnicity (n = 6), and education (n = 5). No systematic reviews assessed medication use errors or healthcare-associated infections. We found very limited assessment of other SDOH measures such as economic stability, neighborhood, and health system access.
Conclusion:
A limited number of systematic reviews have examined the association of race, ethnicity and SDOH measures with inpatient quality measures, and existing reviews highlight wide variability in reporting. Future systematic evaluations of SDOH measures are needed to better understand the relationships with inpatient quality measures.
Schizophrenia is associated with a reduced life expectancy, not only because of suicide, but also medical causes such as cancer. Standardized mortality for cancer is higher in patients with schizophrenia, specially for lung, breast and colorectal locations (Ni et al, 2019). Other less frequent tumor locations have not been deeply studied.
Thir mortality gap could be related to a delayed diagnosis due to several reasons, such as lower inclusion in screening programs (Solmi et al, 2019). Since cervical cancer has a very efficient screening technique, women with schizophrenia and cervical cancer could have a worse prognosis because of a delayed diagnosis. However, there is a lack of research in this tumor location.
Objectives
To analyze clinical differences in women with cervical cancer with and without a diagnosis of schizophrenia.
Methods
We carried out a retrospective cohort analysis with adult patients from the cancer registry of Hospital del Mar diagnosed between 1997 and 2021. The information was crossed with the Minimum Basic Data Set (MBDS) to identify those cancer patients with a diagnosis of schizophrenia using International Classification of Diseases (ICD) 9 codes 295*. The sociodemographic variables were age and sex. The clinical oncological variables included tumor location, place of first conultation, stage, first treatment intention, vital status and place of decease. We used t-student for continuous data and Chi-squared test for categorical variables. We performed a post-hoc analysis using Bonferroni correction for multiple comparisons to identify specifically which categories were significantly different between groups.
Results
We identified 13 women with schizophrenia and cervical cancer, and 1354 women with cervical cancer without schizophrenia. The proportion of this location was higher in the schizophrenia group (8% of all cancers vs. 4.4%; p=0.03). The proportion of diagnoses through screening programm was significantly lower (7.7% vs 14.6%; p=0.04). There was a trend of fewer diagnoses in situ in patients with schizophrenia (30.8% vs 55.6%) and less radical intention as first treatment option (15.4% vs 3.5%) but without statistical significance in both cases. There was a higher proportion of deceased patients in the group with schizophrenia (46.2% vs 15% p=0.002), and also a higher proportion of deaths outside hospital facilities (30.8% vs 6.6%; p=0.003).
Image:
Conclusions
Women with schizophrenia receive less diagnoses of cervical cancer through screening programs and more in emergency facilities, which could lead to more advanced stages and fewer indication of radical treatments. This ultimately leads to a higher proportion of deaths, and more frequently outside of hospital facilities.
Our data supports the idea that the increased mortality for cancer is related to a delayed diagnosis. Women with schizophrenia need special care to ensure their inclusion in early detection programs for cancer.
Women experiencing severe perinatal mental health problems require specialized services and care. Perinatal mental disorders are common and can contribute to maternal mortality, affecting neonatal, infant, and child outcomes. Home treatment can prevent hospital admissions and promote strategies within the patient’s support network.
Objectives
Our aim is to describe a clinical case in perinatal psychiatry managed by a Psychiatric Home Treatment Unit.
Methods
We present a case of perinatal psychotic depression in a 26-year-old pregnant woman.
Results
We describe the case of a patient with no prior history of mental health issues. She was 25 weeks pregnant when she first sought psychiatric help in July 2023 and was diagnosed with depressive disorder with psychotic symptoms. She reported symptoms such as low mood, psychomotor inhibition, delusional guilt thoughts, and auditory hallucinations beginning three weeks before her initial visit. Due to her clinical presentation, the patient was admitted to the hospital, where pharmacological treatment was initiated with Olanzapine 5 mg, Sertraline 50 mg, and Lorazepam 1.5 mg. She remained in the hospital for four days, during which she showed gradual improvement but did not achieve full recovery.
Considering the improvement observed, home treatment was proposed and accepted by the patient and her relatives. During home treatment, she continued to exhibit persistent depressive and psychotic symptoms, including low mood, inhibition, and delusional thoughts of ruin and catastrophe. Therefore, her treatment was adjusted, with Olanzapine increased to 10 mg, Sertraline raised to 100 mg, and Lorazepam reduced to 0.75 mg. Over time, significant improvement in her clinical symptoms was noted. Throughout the follow-up period, she reported no significant side effects from the pharmacological treatment. After a month of follow-up in our department, she was discharged with outpatient care provided by a specialized community perinatal psychiatric unit.
Conclusions
We illustrate the possibility of home treatment for perinatal psychiatric disorders. The potential benefits of remaining close to one’s support network and developing coping strategies can be advantageous during the course of illness. Further studies should be conducted to explore these potential benefits.
Psychotic patients are a vulnerable population from a social and health point of view. The SARS Cov-2 pandemic affected millions of people around the world, however, its effects on psychotic patients in Avilés Spain, have not been analized.
Objectives
The objective of this study was to determine and compare the mortality of patients with psychosis due to SARS Cov-2 in Avilés, Spain with others regions and countries in the European Union. Determine the influence of social condition and antipsychotic treatment on the condition of these patients.
Methods
This is a descriptive, observational study, in which patients diagnosed with psychosis in the period 2020-2021 who contracted SARS Cov-2 infection in Avilés, Spain, were studied to determine those who died from this cause. The influence of social status and antipsychotic medication, as well as sociodemographic factors (age, sex, marital status) were analyzed and compared with other regions and countries of the European Union.
Results
Despite the high mortality rate in patients with psychosis, during the years of the pandemic SARS Cov-2 played an important role given the vulnerability of these patients.
Conclusions
The negative effects and deaths during the COVID-19 pandemic were at the time a major problem for public health worldwide. This study concluded that the morbidity and mortality of psychotic patients who contracted COVID-19 was lower than the rest of the population.
Suicide is a global public health issue. According to the latest available data from the National Institute of Statistics, 4,003 people died by suicide in 2021, reaching a new historical high. Approximately 90% of suicide victims suffer from one or more severe psychiatric disorders, and there is a documented 20-fold higher risk of suicide in individuals with affective disorders compared to healthy subjects (Abdelnaim et al., 2020). Repetitive transcranial magnetic stimulation (rTMS) has been established as an effective alternative or complementary treatment option for patients with depressive disorders, but little is known about its effects on suicide risk.
Objectives
To assess the efficacy of rTMS in reducing depressive symptoms in patients with suicidal ideation and behaviors.
Methods
Population and Methods: A retrospective analysis was conducted on a sample of 28 psychiatric patients (23 females; mean age 49.36 ± 16.23) with suicidal ideation identified by item 3 (suicidality) of the Hamilton Depression Rating Scale (HDRS), who were treated with rTMS. All patients received a minimum of 30 sessions, consisting of the application of a high-frequency (>10Hz) or intermittent theta burst stimulation (TBS) over the left dorsolateral prefrontal cortex (DLPFC) at an intensity of 120% of the resting motor threshold (RMT), and repeated low-frequency pulses (1Hz) or continuous TBS over the right DLPFC with an intensity of 110% of the RMT.
Results
Results: The results show a statistically significant improvement in depressive symptoms following rTMS intervention (p < 0.001). Furthermore, remission was observed in 46% of the sample (HDRS < 8).
Conclusions
Discussion: In line with recent studies (Abdelnaim et al., 2020; Hines et al., 2022) and systematic reviews (Cui et al., 2022; Bozzay et al., 2020) on suicidal ideation in the context of psychiatric disorders, the findings of this study demonstrated that rTMS achieved satisfactory results in reducing depressive symptoms and suicidal ideation.
Conclusions: This clinical study indicates preliminary promise for the prevention of suicidal acts and underscores the need for more detailed and specific research on rTMS in the field of suicide.
As part of the intervention, patients with severe schizophrenia who are cared for in psychiatric rehabilitation units need psychological treatments. However, there is great variability within the psychotherapy alternatives that are proposed for rehabilitation in schizophrenia, and it is necessary to know which are the most efficient interventions in order to prioritize their inclusion in intervention programs.
Objectives
To know the level of evidence of the existing psychotherapy alternatives for the rehabilitation treatment in schizophrenia through the systematic review of recently published studies.
Methods
Consecutive systematic searches in the scientific literature were used in a sensitive and specific way, aimed at identifying the existence of documents in databases and clinical practice guidelines based on evidence of psychological treatment in schizophrenia. Psychosocial and social approaches and family members interventions were excluded, and the search was limited to the last 5 years. The PICO format has been used, and a subsequent critical reading using the AGREE II tool, considering the inclusion criteria of presenting a score >60% in 4 domains.
Results
The following interventions have been found to be therapeutically effective: Level 1B (Early intervention in Psychosis; Patient and Family psychoeducational intervention; Basic ando social skills training; Social cognition and Metakognition training; Cognitive Remediation; Cognitive Behavioral Individual Therapy; Assertive Community treatment; Supported employment). Level 2B (Family Problem Solving Therapy, Dynamic Psychotherapy; Cognitive Behavioral Group Therapy); Level 2C (Horticultural, Art, Music, Animals Therapies).
Conclusions
Several psychotherapy alternatives are proposed for rehabilitation in schizophrenia, with known level of evidenca in order to prioritize their inclusion in intervention programs.
Interest in the co-occurrence of gender dysphoria and autism spectrum disorder has gained prominence in recent years. Gender dysphoria refers to the distress experienced when there is an incongruence between gender identity and sex assigned at birth. On the other hand, autism spectrum disorder is characterized by difficulties in communication and social interaction, as well as restrictive and repetitive patterns of behavior.
Objectives
The aim of this paper is to review the current available literature in order to expand our knowledge about gender identity and dysphoria in the population with autism spectrum disorder.
Methods
A qualitative review was conducted over the last 20 years, using the Medline database through PubMed. Combinations of MeSH terms related to gender identity and people with autism spectrum disorder were used, selecting those studies in English, French or Spanish that met the objectives of the review, excluding references in other languages. The scientific evidence obtained was analyzed and synthesized.
Results
The development of gender identity of people with autism spectrum disorder can be a complex process. Comparing the general population with the population with autism spectrum disorder, a higher prevalence of gender dysphoria has been evidenced in the population with autism spectrum disorder, and within this group when segmented by gender, greater in women than in men.
Conclusions
This review highlights the importance of increasing knowledge about sexuality and gender dysphoria in people with autism spectrum disorder in order to facilitate the development, understanding and acceptance of their gender identity and sexual orientation of these people.
