The First Large Absorption Survey in H i (FLASH) is a large-area radio survey for neutral hydrogen in and around galaxies in the intermediate redshift range $0.4\lt z\lt1.0$, using the 21-cm H i absorption line as a probe of cold neutral gas. The survey uses the ASKAP radio telescope and will cover 24,000 deg$^2$ of sky over the next five years. FLASH breaks new ground in two ways – it is the first large H i absorption survey to be carried out without any optical preselection of targets, and we use an automated Bayesian line-finding tool to search through large datasets and assign a statistical significance to potential line detections. Two Pilot Surveys, covering around 3000 deg$^2$ of sky, were carried out in 2019-22 to test and verify the strategy for the full FLASH survey. The processed data products from these Pilot Surveys (spectral-line cubes, continuum images, and catalogues) are public and available online. In this paper, we describe the FLASH spectral-line and continuum data products and discuss the quality of the H i spectra and the completeness of our automated line search. Finally, we present a set of 30 new H i absorption lines that were robustly detected in the Pilot Surveys, almost doubling the number of known H i absorption systems at $0.4\lt z\lt1$. The detected lines span a wide range in H i optical depth, including three lines with a peak optical depth $\tau\gt1$, and appear to be a mixture of intervening and associated systems. Interestingly, around two-thirds of the lines found in this untargeted sample are detected against sources with a peaked-spectrum radio continuum, which are only a minor (5–20%) fraction of the overall radio-source population. The detection rate for H i absorption lines in the Pilot Surveys (0.3 to 0.5 lines per 40 deg$^2$ ASKAP field) is a factor of two below the expected value. One possible reason for this is the presence of a range of spectral-line artefacts in the Pilot Survey data that have now been mitigated and are not expected to recur in the full FLASH survey. A future paper in this series will discuss the host galaxies of the H i absorption systems identified here.
Accurate diagnosis of bipolar disorder (BPD) is difficult in clinical practice, with an average delay between symptom onset and diagnosis of about 7 years. A depressive episode often precedes the first manic episode, making it difficult to distinguish BPD from unipolar major depressive disorder (MDD).
Aims
We use genome-wide association analyses (GWAS) to identify differential genetic factors and to develop predictors based on polygenic risk scores (PRS) that may aid early differential diagnosis.
Method
Based on individual genotypes from case–control cohorts of BPD and MDD shared through the Psychiatric Genomics Consortium, we compile case–case–control cohorts, applying a careful quality control procedure. In a resulting cohort of 51 149 individuals (15 532 BPD patients, 12 920 MDD patients and 22 697 controls), we perform a variety of GWAS and PRS analyses.
Results
Although our GWAS is not well powered to identify genome-wide significant loci, we find significant chip heritability and demonstrate the ability of the resulting PRS to distinguish BPD from MDD, including BPD cases with depressive onset (BPD-D). We replicate our PRS findings in an independent Danish cohort (iPSYCH 2015, N = 25 966). We observe strong genetic correlation between our case–case GWAS and that of case–control BPD.
Conclusions
We find that MDD and BPD, including BPD-D are genetically distinct. Our findings support that controls, MDD and BPD patients primarily lie on a continuum of genetic risk. Future studies with larger and richer samples will likely yield a better understanding of these findings and enable the development of better genetic predictors distinguishing BPD and, importantly, BPD-D from MDD.
Past hydrogeological processes and human impacts may exert substantial memory effects on today’s groundwater systems. Thorough characterization of such long-term processes is required for scientists and policymakers to predict the hydrogeological impacts of land management options. Especially in data-scarce areas, historical data are essential to unravel long-term hydrogeological processes, which could not be identified by short-term fieldwork or model simulations alone. However, historical data are often overlooked or only used as background information in most hydrogeological studies. We show that the combination of historical reports and quantitative data yields major insights in the hydrogeological system of Curaçao, a small semi-arid Caribbean island. Reconstructing the island’s groundwater conditions over the past 500 years revealed that deforestation and excessive abstraction has had a detrimental effect on the island’s groundwater reserves. Historical notes and data revealed major signs of seawater intrusion, especially during abstraction peaks in the island’s industrial era. Intrusion effects are still observed locally on the island today, but additional groundwater recharge by waste water has caused freshening elsewhere. We hypothesize that the observed aquifer replenishment locally enhances submarine groundwater discharge, flushing accumulated nutrients and pollutants towards Curaçao’s fringing coral reefs. We expect that this study’s insights motivate more hydrogeologists to use historical reports and data in future studies.
In response to the COVID-19 pandemic, we rapidly implemented a plasma coordination center, within two months, to support transfusion for two outpatient randomized controlled trials. The center design was based on an investigational drug services model and a Food and Drug Administration-compliant database to manage blood product inventory and trial safety.
Methods:
A core investigational team adapted a cloud-based platform to randomize patient assignments and track inventory distribution of control plasma and high-titer COVID-19 convalescent plasma of different blood groups from 29 donor collection centers directly to blood banks serving 26 transfusion sites.
Results:
We performed 1,351 transfusions in 16 months. The transparency of the digital inventory at each site was critical to facilitate qualification, randomization, and overnight shipments of blood group-compatible plasma for transfusions into trial participants. While inventory challenges were heightened with COVID-19 convalescent plasma, the cloud-based system, and the flexible approach of the plasma coordination center staff across the blood bank network enabled decentralized procurement and distribution of investigational products to maintain inventory thresholds and overcome local supply chain restraints at the sites.
Conclusion:
The rapid creation of a plasma coordination center for outpatient transfusions is infrequent in the academic setting. Distributing more than 3,100 plasma units to blood banks charged with managing investigational inventory across the U.S. in a decentralized manner posed operational and regulatory challenges while providing opportunities for the plasma coordination center to contribute to research of global importance. This program can serve as a template in subsequent public health emergencies.
The objectives of this experiment were to determine the digestible indispensable amino acid score (DIAAS) for eggs cooked in different forms and in traditional egg-bread or egg-hash brown combinations, and to test the hypothesis that DIAAS in eggs is greater than in breads or potatoes. Nine ileal cannulated gilts (average initial body weight: 51.1 ± 6.0 kg) were allotted to a 9 × 6 Youden square design with nine diets and six 7-day periods. Fried egg, boiled egg, scrambled egg, English muffin, Texas toast, and hash brown were included in the experiment. Six diets each contained one source of protein and three diets were combinations of fried eggs and English muffin, boiled eggs and Texas toast, or scrambled egg and hash brown. A nitrogen-free diet was also used and fed to all pigs in one period. The standardised ileal digestibility (SID) of crude protein (CP) and amino acids (AA) was calculated, and DIAAS was calculated for the individual ingredient and combined meals for children between 6 and 36 months and individuals older than 3 years. For both age groups, all cooked eggs had greater (P < 0.001) DIAAS compared with the other foods, and hash brown had greater (P < 0.001) DIAAS than both breads. All combined meals had DIAAS greater than 75 and there were no differences between measured and predicted DIAAS for the combined meals. In conclusion, eggs have ‘excellent’ protein quality for individuals older than 6 months and can compensate for the lower protein quality in plant-based foods, and DIAAS obtained from individual ingredients are additive in mixed meals.
Dioctophyme renale, the giant kidney worm, is a nematode related to Trichuris sp and is distributed worldwide. These parasites locate in the kidney of their definitive hosts (mainly belonging to the order Carnivora) and have an indirect life cycle with an annelid as the main intermediate host. Humans are rarely affected, but in those that are, 1 or both kidneys are destroyed. In South America, D. renale is widespread in riparian regions where changing climatic conditions, environmental degradation, and compromised sanitation are increasing the risk of distribution of this parasite, including humans. Here, we provide the descriptions of the genetic diversity of the parasite in the region by analysing 73 adult D. renale samples collected from domestic and wild carnivores. The most common hosts were (Canis lupus familiaris) and maned wolf (Chrysocyon brachyurus Fam. Canidae) among domestic and wild carnivores, respectively. This work shows the descriptions of the genetic diversity of this parasite complementing molecular methods and classical and probabilistic phylogeography. Our results strongly suggest that this parasite has been present on the continent long enough to develop local genetic variants. Also, the phylogenies show transmission between localities and bidirectional transmission between domestic and wild species. We now have new tools to understand the ecological dynamics of this parasite such as molecular markers to study its genetic diversity as well as for identification and reporting in cryptic cases.
Diagnostic criteria for major depressive disorder allow for heterogeneous symptom profiles but genetic analysis of major depressive symptoms has the potential to identify clinical and etiological subtypes. There are several challenges to integrating symptom data from genetically informative cohorts, such as sample size differences between clinical and community cohorts and various patterns of missing data.
Methods
We conducted genome-wide association studies of major depressive symptoms in three cohorts that were enriched for participants with a diagnosis of depression (Psychiatric Genomics Consortium, Australian Genetics of Depression Study, Generation Scotland) and three community cohorts who were not recruited on the basis of diagnosis (Avon Longitudinal Study of Parents and Children, Estonian Biobank, and UK Biobank). We fit a series of confirmatory factor models with factors that accounted for how symptom data was sampled and then compared alternative models with different symptom factors.
Results
The best fitting model had a distinct factor for Appetite/Weight symptoms and an additional measurement factor that accounted for the skip-structure in community cohorts (use of Depression and Anhedonia as gating symptoms).
Conclusion
The results show the importance of assessing the directionality of symptoms (such as hypersomnia versus insomnia) and of accounting for study and measurement design when meta-analyzing genetic association data.
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.
Tourette’s syndrome (TS) is a disorder characterized by repetitive, involuntary movements, and vocalizations known as tics. While there are existing treatment options, there is a growing need for novel pharmacological approaches to manage the symptoms of TS effectively. This study delves into the emerging field of using cannabinoids as a potential treatment for Tourette’s syndrome.
Objectives
The primary objectives of this review are to examine the current evidence base for the use of cannabinoids in the treatment of Tourette’s syndrome, to assess the biological rationale supporting the use of cannabinoids in managing tic severity, to provide insights into the results of existing clinical trials involving cannabinoids and Tourette’s syndrome, and to draw conclusions regarding the potential efficacy and safety of cannabinoid-based treatments for TS.
Methods
Narrative review of the available scientific literature.
Results
There is a strong biological rationale for how cannabinoids could impact tic severity. The endocannabinoid system plays a crucial role in regulating various physiological processes, including motor control and neurotransmitter release. Activation of cannabinoid receptors in the brain may modulate these processes, potentially reducing tics. While limited, two small randomized, placebo-controlled trials of THC have been conducted in TS patients. These trials suggested potential benefits of cannabis-derived agents in reducing tic frequency and severity. Self-report and examiner rating scales demonstrated significant improvements in tic symptoms. The trials indicated that THC treatment did not result in significant adverse effects in TS patients.
Conclusions
The exploration of cannabinoids as a treatment option for Tourette’s syndrome is promising but requires further investigation. The biological mechanisms through which cannabinoids may affect tic severity in TS are sound, suggesting their potential as a therapeutic option. Existing trials with THC have shown encouraging results, demonstrating a reduction in tics without significant adverse effects. However, the limited number of trials warrants caution in drawing definitive conclusions. Despite the promising findings, the overall efficacy and safety of cannabinoid-based treatments remain largely unknown. Further trials are essential to address dosing, active ingredients, optimal administration, and potential long-term effects. Clinical use should be approached with caution. While early evidence is encouraging, additional rigorous studies are needed to establish the safety and efficacy of cannabinoid-based treatments for this disorder.
Irvin D. Yalom defines existential psychotherapy as a dynamic therapeutic approach that focuses on concerns rooted in existence with the four ultimate concerns being death, isolation, meaning in life, and freedom. Patients in advanced stages of cancer often experience elevated levels of psychological distress, encompassing conditions such as depression, anxiety, and a sense of spiritual hopelessness. Recently, interest in spiritual well-being has prompted a new wave of interventions that directly target this population, namely logotherapy and other existential interventions based on existential principles.
Objectives
In this review, the primary focus was to comprehend the current evidence on the application of existential psychotherapy for individuals coping with advanced cancer and give an overview of the therapy approaches used.
Methods
Narrative review of scientific literature using Pubmed search engine.
Results
Terao and Satoh identified nine types of existential psychotherapies which were investigated using randomized controlled trials for patients with advanced cancer or in terminal care: Meaning-Centered Group Psychotherapy (MCGP), Individual Meaning-Centered Psychotherapy (IMCP), Meaning-Making intervention (MMi), Meaning of Life Intervention, Managing Cancer and Living Meaningfully (CALM), Hope Intervention, Cognitive and Existential Intervention, Dignity Therapy, and Life-Review Interviews. All deal with the issues pointed by Yalom. Existential or spiritual well-being improvements were validated in MCGP, IMCP, Meaning of Life intervention, and Life-Review intervention.
Conclusions
Current evidence is still based on a very limited number of studies. Additional research is needed to delve into the impact of existential psychotherapy on individuals facing advanced cancer.
tardive dysphoria is a relatively new term used to describe the phenomenon of clinical worsening of depression after long-term antidepressant use. Most of the theories proposed to explain this talk about antidepressants tachyphylaxis that implies the loss of efficacy with its prolonged use, or even a pro-depressant effect of antidepressants when used for long periods of time.
Objectives
to explore the concept of tardive dysphoria, potential causes and clinical implications, by making a literature review on the topic. Moreover we pretend to understand the challenges in its diagnosis and treatment.
Methods
bibliographical search in PubMed database, using the key-words “long-term antidepressant”, “tardive dysphoria” and “antidepressant tachyphylaxis”, limited to works published in the last twenty years.
Results
from our search resulted 53 articles, 26 were chosen for further analysis.
Conclusions
the concept of tardive dysphoria is controversial, namely doubt persists if it constitutes a clinical entity by itself caused by long-term antidepressant use or if it simply relates to cases of treatment-resistant depression. We conclude that it is necessary further investigation in this area given the significant implications on clinical practice specifically in the psychopharmacological treatment with antidepressants, which is very common in psychiatric and general practices, with antidepressants being used to treat many mental health conditions.
In the review of recent literature, we found very few presentations of case reports in which the presumed association between psychiatric disorders and arachnoid cysts is discussed. Arachnoid cysts are rare brain tumors with little apparent symptomatic impact and in most cases, they are diagnosed incidentally. We present the case of a 15-year-old adolescent with a personal history of a previous severe depressive episode, as well as suspicion of serious mental pathology in the family. It presents a subacute onset episode, in the context of regular cannabis consumption, consisting of intense emotional lability and psychomotor restlessness, a tendency toward irritability, decreased sleep needs, and the appearance of delusional ideas of harm and self-referential interruption. During the study of the case, and incidentally, the cranial magnetic resonance imaging revealed the presence of an arachnoid cyst located in the left frontotemporal location, approximately 4 cm in diameter.
Objectives
(1) To describe the clinical particularities of this case, focusing on the diagnostic difficulties we faced. (2) To review current scientific evidence regarding the possible association between neuropsychiatric symptoms and arachnoid cysts.
Methods
A review of the patient’s clinical history was carried out and complementary tests were performed. Likewise, a review of the available scientific literature was also performed in relation to the appearance of neuropsychiatric symptoms associated with the presence of arachnoid cysts.
Results
The literature regarding the possible association between psychosis and arachnoid cysts is scarce. However, it is proposed that arachnoid cysts may be associated with various neuropsychiatric alterations, such as affective alterations, schizophrenia-like psychosis or amnestic symptoms. The atypicality in the symptoms sometimes leads us to suspect an organic origin of the condition, with some features such as associated memory deficits, emotional incontinence, movement disorders or neurological focal data; some of which are present in the case at hand.
Conclusions
There is controversy among different sources regarding the role of the cyst in the development of symptoms or, on the contrary, its presentation only as a chance finding. Further investigation focusing on clinical observations and neuroimaging is needed.
A variety of peer support workers have been integrated in the mental health workforce in several countries. The effectiveness of this approach is still inconclusive. However, some data reveals promising results. Some projects have integrated peer support intervention in the treatment of psychosis. In fact, UK clinical guidelines for psychosis advise the inclusion of peer support within Early Intervention in Psychosis services.
Objectives
The current study aims to evaluate how peer support may assist the intervention in psychosis and highlight challenges ahead in this field.
Methods
Narrative review of the available scientific literature.
Results
Research suggests that consistent and frequent peer support enhances social support and boosts self-confidence and the overall quality of life for people going through psychosis. Individuals diagnosed with severe mental illnesses who receive peer support reportedly experience an increased sense of control, hopefulness, and empowerment, enabling them to initiate positive changes in their lives. People going through psychosis experience internalized stigma. Destigmatization of psychotic experiences is a central theme of intervention in psychosis. Participants viewed peer support as a valuable form of assistance that could offer advantages to both peers (service users) and peer support workers.
Conclusions
Peer support makes a strong contribution to destigmatising psychosis. The available date is promising and supports the effectiveness of peer support in such instances. As projects of peer support in psychosis continue to be implemented, further research should provide additional insight into the effectiveness and inherent challenges of this type of intervention.
Psychotherapy serves as the foundation of care for individuals with borderline personality disorder (BPD), with pharmacotherapy being regarded as a supplementary measure to be considered when necessary. In clinical practice, however, most of BPD patients receive medication.
A major problem in the treatment of BPD is the lack of compliance derived from the pathological impulsivity of BPD patients. The use of long-acting antipsychotics (LAI) may be an option.
Objectives
This work aims to address the use of long-acting injectables in borderline personality disorder.
Methods
Non-systematic review of literature using the PubMed ® database, based on terms “Borderline Personality Disorder” and “Long-acting antipsychotics”. Only six articles were found.
Results
Several studies have shown promising results in the treatment of Borderline Personality Disorder (BPD) with long-acting injectable (LAI) antipsychotics. A six-month study using IM risperidone demonstrated significant improvement, while LAI Aripiprazole also exhibited positive outcomes in individuals with BPD and Substance Abuse. Additionally, Palomares et al. (2015) found that palmitate paliperidone LAI reduced impulsive-disruptive behaviors and enhanced overall functioning in BPD patients. Carmona et al. (2021) compared oral and LAI antipsychotics and concluded that LAIs may have a role to play in the management of BPD.
Conclusions
Treatment with LAIs may play an important role in clinical and functional improvement in BPD patients.
Psychiatric patients, and schizophrenia patients in particular, have a lower average life expectancy than the general population, and the high prevalence of physical illnesses contributes to this. In the case of cancer, the incidence seems to be the same or lower compared to the general population, but on the other, the prognosis is frankly worse.
Objectives
We aim to collect evidence about the relationship between cancer and schizophrenia.
Methods
Based on a clinical case of a patient diagnosed with schizophrenia who died of an occult neoplasm, we conducted a narrative review of the literature concerning cancer screening, incidence, mortality and prognosis in patients with schizophrenia.
Results
A 39-year-old male patient was diagnosed with schizophrenia when he was 26 years older. The patient was single, had no children, lived alone and was retired due to his psychiatric condition.
He was admitted to the inpatient ward in January 2023 due to a psychotic relapse after abandoning the prescribed treatment. He remained hospitalised for 14 days, and oral and injectable antipsychotic therapy was reinstated. He was discharged to the psychiatric day hospital unit to promote psychosocial rehabilitation. During this period, he complained about unspecified back pain but did not present any other physical symptoms.
Two months later, he was evaluated by his psychiatrist as an outpatient, and his general condition had become significantly poorer. He had lost over 20 kilograms, his skin was pale, and he complained of back pain. He was referred to an internal medicine consultation. Still, before it was scheduled, he came to the emergency department and was admitted due to digestive bleeding, asthenia and low back pain, with a weight loss of around 25 kilograms.
An abdominal mass was palpated on physical examination, and the chest x-ray showed a “balloon drop” pattern, indicating pulmonary metastases. Two days after being admitted to the internal medicine ward, he died of cardiac arrest.
It is known that the stigma that mentally ill patients suffer often contributes to a delay in diagnosing medical illnesses. In addition, frequent social isolation and poor social family support do not help these patients seek medical care when their physical condition deteriorates. Low adherence to cancer screening and avoidance of routine health care often add to this delay.
Conclusions
As physicians who often deal with individuals with severe mental illnesses, psychiatrists should be extra aware of risk factors and keep a heightened suspicion of medical conditions. They should also promote the adoption of beneficial health behaviours and encourage participation in cancer screening and other relevant health programs.
The population ageing is a reality associated with an increase in prevalence of Dementia. The use of benzodiazepines is often postulated as a risk factor in these syndromes.
Contrary to recommendations for its short-time use, long-term and chronic use are common, with an estimated 8,7% of elderly people in the US taking benzodiazepines.
Objectives
To clarify the most recent evidence on the use of benzodiazepines and the risk of developing dementia.
Methods
Non-systematic review of literature, using PubMed as database and filtering the results for meta-analysis.
Results
Four articles were included in this review.
Zhong G et al. concluded that risk of dementia increased in consumers of benzodiazepines and it was associated with higher doses.
In turn, AlDawasari A et al., when trying to clarify the use of different sedative-hypnotic drugs, found and increased risk with the consumption of benzodiazepines. After exclusion of articles with confounders and adjustment for protopathic bias, the risk was not maintained.
Lucchetta RC et al. concluded that the risk exists but without inferring differences between doses or duration of action.
Finally, Penninkilampi R e Eslick GD investigated this association, after controlling for the protopathic bias, concluding, contrary to AlDawasari et al., that the association benzodiazepines consumption and dementia do not result from this bias.
Conclusions
We cannot draw robust and concrete conclusions between benzodiazepines consumption and the pathogenesis of dementia because not only is the literature limited, but results are also heterogeneous.
However, these prescriptions must be carried out cautiously, especially in the elderly, due to the known adverse effects associated with them.
Sucrose yield in sugarcane is a complex process regulated by both environmental and endogenous factors. However, the metabolic balance driving vegetative growth and sucrose accumulation remains poorly understood. Herein, we carried out a comprehensive assessment of carbohydrate dynamics throughout the crop cycle in two sugarcane varieties varying in biomass production, evaluating the carbon metabolism in both leaves and stalks. Our data revealed that the decline in photosynthetic rates during sugarcane maturation is associated not only to accumulation of sugars in leaves but also due to stomatal and non-stomatal limitations. We found that metabolic processes in leaves and stalks were intrinsically linked. While IACSP94-2094 had higher stalk sucrose concentration than IACSP95-5000, this latter produced more biomass. Compared to IACSP95-5000, IACSP94-2094 showed higher sucrose phosphate synthase (SPS) activity in leaves and stalks, along with lower soluble acid invertase (SAI) activity in leaves during the maximum growth stage. Interestingly, IACSP94-2094 also exhibited higher stalk SPS activity and lower stalk SAI activity than IACSP95-5000 during maturation. High biomass production by IACSP95-5000 was associated with higher sucrose synthase (SuSy) and SAI activity in leaves and higher SuSy and soluble neutral invertase (SNI) activity in stalks when compared to IACSP94-2094 during the maximum growth. Despite the contrasting strategies, both varieties displayed similar total sucrose yield, a balance between sucrose concentration and biomass production. This phenomenon implies the presence of a compensatory mechanism in sugarcane, with high biomass production compensating low sucrose accumulation and vice versa.
The Minnesota Longitudinal Study of Risk and Adaptation (MLSRA) is a landmark prospective, longitudinal study of human development focused on a sample of mothers experiencing poverty and their firstborn children. Although the MLSRA pioneered a number of important topics in the area of social and emotional development, it began with the more specific goal of examining the antecedents of child maltreatment. From that foundation and for more than 40 years, the study has produced a significant body of research on the origins, sequelae, and measurement of childhood abuse and neglect. The principal objectives of this report are to document the early history of the MLSRA and its contributions to the study of child maltreatment and to review and summarize results from the recently updated childhood abuse and neglect coding of the cohort, with particular emphasis on findings related to adult adjustment. While doing so, we highlight key themes and contributions from Dr Dante Cicchetti’s body of research and developmental psychopathology perspective to the MLSRA, a project launched during his tenure as a graduate student at the University of Minnesota.
