We introduce a new approach to quantifying dust in galaxies by combining information from the Balmer decrement (BD) and the dust mass (Md). While there is no explicit correlation between these two properties, they jointly probe different aspects of the dust present in galaxies. We explore two new parameters that link BD with Md by using star formation rate sensitive luminosities at several wavelengths (ultraviolet, Hα, and far-infrared). This analysis shows that combining the BD and Md in these ways provides new metrics that are sensitive to the degree of optically thick dust affecting the short wavelength emission. We show how these new “dust geometry” parameters vary as a function of galaxy mass, star formation rate, and specific star formation rate. We demonstrate that they are sensitive probes of the dust geometry in galaxies, and that they support the “maximal foreground screen” model for dust in starburst galaxies.
Background: The fragility index (FI) is the minimum number of patients whose status would have to change from a nonevent to an event to turn a statistically significant result to a non-significant result. We used this to measure the robustness of trials comparing carotid endarterectomy (CEA) to carotid artery stenting (CAS). Methods: A search was conducted in MEDLINE, Embase, and PubMed on RCTs comparing CEA to CAS. The trials need to have statistically significant results and dichotomous primary endpoints to be included. Results: Our literature search identified 10 RCTs which included 9382 patients (4734 CEA, 4648 CAS). The primary end points of all included trials favoured CEA over CAS. The median FI was 9.5 (interquartile range 2.25 - 21.25). All of the studies that reported lost-to-follow-up (LTFU) had LTFU greater than its fragility index, which raises concern that the missing data could change the results of the trial from statistically significant to statistically insignificant. Conclusions: A small number of events (FI, median 9.5) were required to render the results of carotid artery stenosis RCTs comparing CEA to CAS statistically insignificant. All of the studies that reported LTFU had LTFU greater than its fragility index.
We demonstrate the importance of radio selection in probing heavily obscured galaxy populations. We combine Evolutionary Map of the Universe (EMU) Early Science data in the Galaxy and Mass Assembly (GAMA) G23 field with the GAMA data, providing optical photometry and spectral line measurements, together with Wide-field Infrared Survey Explorer (WISE) infrared (IR) photometry, providing IR luminosities and colours. We investigate the degree of obscuration in star-forming galaxies, based on the Balmer decrement (BD), and explore how this trend varies, over a redshift range of $0<z<0.345$. We demonstrate that the radio-detected population has on average higher levels of obscuration than the parent optical sample, arising through missing the lowest BD and lowest mass galaxies, which are also the lower star formation rate (SFR) and metallicity systems. We discuss possible explanations for this result, including speculation around whether it might arise from steeper stellar initial mass functions in low mass, low SFR galaxies.
Using two rounds of serosurveillance, we aimed to observe the COVID-19 vaccination status and the dynamics of antibody responses to different vaccines among urban slum and non-slum populations of Bangladesh. Adults (>18 years) and children (10–17 years) were enrolled in March and October 2022. Data including COVID-19 vaccine types and dosage uptake were collected. SARS-CoV-2 spike (S)-specific antibodies were measured in blood. The proportion of vaccinated children was significantly lower among slum than non-slum populations. Two doses of vaccines showed an increase in the level of anti-S-antibodies up to 2 months, followed by reduced levels at 2–6 months and a resurgence at 6–12 months. Children showed significantly higher anti-S-antibodies after two doses of the Pfizer–BioNTech vaccine than adults; however, after 6 months, the level of antibodies declined in younger children (10 - < 12 years). In a mixed vaccine approach, mRNA vaccines contributed to the highest antibody response whether given as the first two doses or as the third dose. Our findings emphasized the need for increasing the coverage of COVID-19 vaccination among slum children and booster dosing among all children. The use of mRNA vaccines in the mixed vaccination approach was found to be useful in boosting the antibody response to SARS-CoV-2.
Much has been learned about SARS-CoV-2. However, the mechanism of short or long-term neuropsychiatric symptoms remains unclear. several hypotheses, including lack of oxygen caused by lung damage, inflammation affecting brain cells, or Lack of blood flow caused by swelling of the small blood vessels in the brain, have been advanced to explain these symptoms.
Objectives
Herein, we presented a case of cognitive impairment diagnosed after infection with COVID 19.
Methods
We discussed, through a clinical case, the possible mechanisms and risk factors of cognitive impairment following COVID 19 infection.
Results
This case concerned a 28 –year-old patient. He had no personal or family psychiatric. In August 2021, he presented a SARS-CoV-2 infection without hypoxemia or respiratory failure. On day 10 the patient recovered. Two days after, he consulted our psychiatric department as he experienced impairment in memory. He had impairment in attention and executive function, and in particular verbal fluency. He said that his thinking was sluggish, fuzzy, and not sharp. He denied any alcohol or drug abuse. He was euthymic and he had no depressive symptoms. Arterial blood gas, laboratory, and clinical findings were normal. A brain CT scan with contrast was performed and did not show any abnormality.
Conclusions
This case highlighted the possible cognitive consequences of COVID-19 during the recovery phase. Further work is required to identify risk factors of psychiatric symptoms following COVID-19 infection and their management.
The little-known Bristled Grassbird Chaetornis striata is thought to be declining due to the loss of grassland habitats throughout its range, and is currently classified as globally ‘Vulnerable’. In order to investigate the current status and possible causes of the presumed decline, we assessed population density of Bristled Grassbird in Padma and Jamuna river systems of Bangladesh. The study was conducted during the breeding seasons of the Bristled Grassbird in April and May in 2016–2019, using distance sampling and habitat suitability modelling. We also examined habitat preferences and responses to environmental changes based on vegetation structure and habitat modifications at point count locations. We detected a total of 39 birds with a mean group size of 1.44 individuals. We estimated 4.52 (95% CI: 2.65–7.73) individuals per km2 with an encounter rate of 1.48 detections per point count station and 341.15 birds within the study area. Our habitat suitability model projected a total of 167.41 km2 of suitable habitat and a total of 756.7 birds in floodplain grasslands of Padma and Jamuna river systems. The Bristled Grassbird was positively associated with grass height and grass density with 92.31% of 39 detections at Saccharum spontaneum dominated grasslands. We did not find a significant effect on Bristled Grassbird detections with increasing human activities, although the detection rate decreased linearly with increasing agricultural intervention and grass harvesting. These findings indicate that the Bristled Grassbird is more widely distributed throughout Bangladesh, and may be less vulnerable to grassland modifications, than previously thought.
Background: A correlation between the nerve root sedimentation sign (SedSign) and neurogenic claudication has been demonstrated; though it did not account for leg-dominant pain. This study analyzed the utility of SedSign to diagnose leg-dominant pain using validated classification systems. Methods: We retrospectively reviewed prospective data from 367 patients with back or leg pain collected between January 1, 2012 to May 31, 2018. Baseline characteristics included SSPc (Saskatchewan Spine Pathway classification), Oswestry disability index (ODI), visual analogue pain scores (VAS), and EuroQol Group 5-Dimension Self-Report (EQ5D). Inter- and intra-rater reliability for SedSign was 73% and 91%. Results: SedSign was positive in 111 (30.2%) and negative in 256 (69.8%) patients. Univariate analysis showed a correlation between SedSign and age, male sex, ODI, EQ5D, cross-sectional area (CSA) of stenosis, antero-posterior diameter of stenosis, and leg-dominant pain; negative SedSign was correlated with back-dominant pain. Multivariate analysis revealed an association between SedSign and age, male sex, CSA stenosis, and ODI walking distance. The sensitivity, specificity, positive and negative predictive values of SedSign for leg-dominant pain were 33.5%, 83.2%, 77.0%, and 57.3%. Conclusions: SedSign has high specificity but low sensitivity for leg-dominant pain. Despite a similar correlation between SedSign and neurogenic claudication or sciatica, significance was lost on multivariate analysis.
Biological rhythms play an important role in the etiology of mood disorders. Several lines of evidence established a link between circadian rhythm disruption and mood episodes. Chronotypes are the behavioral manifestations of circadian rhythms and eveningness appears to be more frequent in bipolar disorder (BD). The influence of chronotype on mood symptoms needs yet to be clarified.
Objectives
-Identifying the predominant chronotype in a Tunisian sample of patients with BD -Assessing the association between chronotype and biological rhythm disruptions in the sample
Methods
For this study, a total of 80 euthymic outpatients with bipolar disorder and 80 control subjects were recruited. Biological rhythms disruptions were assessed using the Biological Rhythm Interview of Assessment in Neuropsychiatry (BRIAN). Predominant chronotype was identified using the composite scale of morningness (CSM).
Results
BRIAN scores showed greater biological rhythms disruptions in bipolar patients than the control subjects (mean scores 35.26±9.21 vs 25.84±2.68). Low CSM scores in the patients’ group indicated a predominant evening chronotype whereas an intermediate chronotype was more frequent within the control group. The correlation analysis revealed a statistically significant negative correlation between the 2 scales (r=-0.716, p<0.001): the CSM scores decreased as the BRIAN scores increased.
Conclusions
This study indicates that eveningness is more common in BD. This chronotype is more likely to disturb biological rhythms which may increase the risk of mood symptoms and lead to a poor prognosis for BD, thus the relevance of treating rhythm alterations, especially in evening-type patients, in order to improve their quality of life and prevent mood episodes.
Biological rhythm disturbance is etiologically involved in mood disorders. Previous literature focused on studying sleep disruption in bipolar disorders (BD). However, only a few studies addressed the influence of social rhythms and occupational functioning as they may affect circadian regularity and consequently be a critical pathway to mood symptoms.
Objectives
The main aim of this study was to assess biological rhythms in remitted bipolar patients and to evaluate their social rhythms and occupational functioning.
Methods
We recruited a total of 80 euthymic outpatients with BD and 80 control subjects. Biological rhythm disruptions were assessed using the Biological Rhythm Interview of Assessment in Neuropsychiatry (BRIAN), an interviewer administered questionnaire that assesses disruptions in sleep, eating patterns, social rhythms, and general activity.
Results
Patients with BD experienced greater biological rhythm alterations than the control group (BRIAN total scores 35.26±9.21 vs. 25.84±2.68). In addition to their sleep-wake rhythm (mean scores 11.1±3.95 vs. 7.41±1.41), patients were particularly more impaired than the control group with regards to social rhythms (7.31 ± 2.57 vs. 5.24 ± 1.06) and general activity (8.9 ± 3.35 vs. 7.01 ± 1.4).
Conclusions
Our study indicated that patients with BD experience major disruptions in their social rhythms and occupational functioning. These alterations may lead to unstable biological rhythms and to a higher risk of mood episodes. Therefore, consolidating social rhythms and functioning appears to be a crucial step for preventing relapses in patients with BD.
Nurses and paramedics by being the frontline workers of the health-care profession need to be equipped with the relevant knowledge, skills, and protective gears against different forms of infection, including coronavirus disease 2019 (COVID-19). Although the governments and concerned stakeholders have provided personal protective equipment (PPE), training and information to protect the health-care professionals; however, until now the scientific literature has virtually not reported the impact of PPE availability, training, and practices on the COVID-19 sero-prevalence among the nurses and paramedics. This study aimed to assess the impact of PPE availability, training, and practices on COVID-19 sero-prevalence among nurses and paramedics in teaching hospitals of Peshawar, Pakistan.
Methods:
A cross-sectional survey was conducted with a total of 133 nurses and paramedics as subjects of the study.
Results:
A univariate analysis was done for 4 variables. The findings indicate that the health-care professionals (nurses and paramedics) who have received PPE on time at the start of COVID-19 emergence have fewer chances of contracting the COVID-19 infection (odds ratio = 0.96); while the odds for PPE supplies was 0.73, and the odds of hand hygiene training was 0.95.
Conclusions:
The study concluded that the availability of the PPE, COVID-19–related training, and compliance with World Health Organization recommended practices against COVID-19 were instrumental in protection against the infection and its spread.
To examine the factors that are associated with changes in depression in people with type 2 diabetes living in 12 different countries.
Methods
People with type 2 diabetes treated in out-patient settings aged 18–65 years underwent a psychiatric assessment to diagnose major depressive disorder (MDD) at baseline and follow-up. At both time points, participants completed the Patient Health Questionnaire (PHQ-9), the WHO five-item Well-being scale (WHO-5) and the Problem Areas in Diabetes (PAID) scale which measures diabetes-related distress. A composite stress score (CSS) (the occurrence of stressful life events and their reported degree of ‘upset’) between baseline and follow-up was calculated. Demographic data and medical record information were collected. Separate regression analyses were conducted with MDD and PHQ-9 scores as the dependent variables.
Results
In total, there were 7.4% (120) incident cases of MDD with 81.5% (1317) continuing to remain free of a diagnosis of MDD. Univariate analyses demonstrated that those with MDD were more likely to be female, less likely to be physically active, more likely to have diabetes complications at baseline and have higher CSS. Mean scores for the WHO-5, PAID and PHQ-9 were poorer in those with incident MDD compared with those who had never had a diagnosis of MDD. Regression analyses demonstrated that higher PHQ-9, lower WHO-5 scores and greater CSS were significant predictors of incident MDD. Significant predictors of PHQ-9 were baseline PHQ-9 score, WHO-5, PAID and CSS.
Conclusion
This study demonstrates the importance of psychosocial factors in addition to physiological variables in the development of depressive symptoms and incident MDD in people with type 2 diabetes. Stressful life events, depressive symptoms and diabetes-related distress all play a significant role which has implications for practice. A more holistic approach to care, which recognises the interplay of these psychosocial factors, may help to mitigate their impact on diabetes self-management as well as MDD, thus early screening and treatment for symptoms is recommended.
To examine the effects of chlorpromazine for psychosis-induced aggression or agitation.
Method
We searched the Cochrane Schizophrenia Group Trials Register (2008) for randomised control trials or double blind trials implying randomisation, comparing chlorpromazine with another drug or placebo for people thought to be acutely aggressive due to psychotic illness. For selected studies we extracted data and calculated relative risks (RR) and 95% confidence intervals (CI) on an intention-to-treat basis, based on a fixed-effects model.
Results
118 studies were identified, two met inclusion criteria. One compared oral chlorpromazine with oral thioridazine and one intramuscular chlorpromazine with intramuscular haloperidol.Those allocated chlorpromazine did not remain on medication (RR 2.00 CI 0.94 to 4.26), or stay in hospital (RR 1.87 CI 0.70 to 4.95) longer than those allocated thioridazine. No differences were found for adverse effects.Those allocated chlorpromazine were no more likely to have one (RR 3.00 CI 0.13 to 68.26), 2-4 (RR 0.90 CI 0.52 to 1.55) or 5+ (RR 0.75 CI 0.20 to 2.79) injections than those allocated haloperidol. Two patients allocated chlorpromazine had, serious hypotension (RR 5.00 CI 0.26 to 96.13), one developed status epilepticus (RR 3.00 CI 0.13 to 68.26), no one allocated haloperidol had these effects
Conclusion
Overall the quality of evidence is limited and dated. Chlorpromazine was just as effective as similar medicines, but it may be associated with more side effects. Where better, more evaluated drugs are available it may be best to avoid using chlorpromazine. Carefully designed clinical trials are urgently needed.
The discharge letter plays a crucial role in continuity of care from secondary to primary care. We found no existing study of outpatient discharge letters, including Mental Retardation services. New Ways of Working for psychiatrists has encouraged the discharge of stable outpatients to primary care in order to provide a responsive, flexible service. This study set standards for discharge communication and identified areas for improvement.
Methodology
This was a retrospective random audit of 30 service users discharged from a psychiatric outpatient clinic. Standards were set with consultant psychiatrists and general practioners. Data was collected from the service users’ last two clinic letters using a pre-developed audit tool and compared the current practice with the standards identified.
Results
Standards for status and future planning were largely achieved with reference to current mental state (97%), current medication (90%), other LD professionals involved (95%), advice and how to re-refer (90%).Standards for historical factors were partially achieved; including summary of contact with services (70%), summary (57%) and evaluation (67%) of treatments received. Some standards were not achieved; including requesting view of primary care prior to discharge (27%), statement of capacity (23%), risk factors (23%) and relapse indicators (27%).
Conclusion
The audit showed areas of good practice and areas for improvement. Results were disseminated to MDT's and a template developed for outpatient discharge letters. A re-audit has commenced to ensure progress in this important information-sharing process and to enhance the delivery of safe and effective health care.
Risperidone has been recommended for the management of disruptive behaviour disorders in children with learning disabilities. This study explored the effects of Risperidone on absolute body weight in children with learning disabilities who received Risperidone for disruptive behaviour disorders.
Methodology
Data was collected for children (n = 70) with learning disabilities who were prescribed Risperidone for disruptive behaviour disorders in out patient clinic. Weight, height and BMI were recorded at the first appointment and at the follow up for up to one year. Data was analysed to find any changes in weight and BMI during the course of treatment with Risperidone.
Results
Mean weight gain for the sample was 6.1 kg (sd = 2.7), 1.7 kg more than expected in one year which was statistically significant (t = 6.2, df = 69, p < 0.001). Mean BMI change was 1.51 kg; significantly larger than the mean expected BMI change of 0.62 of this sample (t = 4.98, df = 1.6, P = 0.001). Change in BMI was more for girls, 2.17 (sd = 1.00) compared with boys 1.36 (sd = 1.18), but this was not significant (t = 1.90, df = 49, p = 0.06). There is no significant relationship between Risperidone dose and weight gain (Pearson's r = 0.21, p = 0.42) and BMI (Pearson's r = 0.03, p = 1.00).
Conclusion
Risperidone should be used with caution in children where weight gain could have long lasting impact. Prescribing clinicians should obtain baseline measures of weight, height, BMI and monitor them at regular intervals. Emphasis should be placed on life style interventions such as diet, physical activities etc. Further comparable studies with larger sample sizes using more homogenous diagnostic samples are needed.
Our aim was to describe the contribution of ‘Low and middle-income’ (LAMI) countries to six leading general psychiatric journals; Archives of General Psychiatry, American Journal of Psychiatry, Journal of Clinical Psychiatry, British Journal of Psychiatry, Acta Psychiatrica Scandinavica and Psychological Medicine.
Methods
We surveyed the journals from January 2005 to December 2009. We searched all research articles, reviews and identified potential candidate articles, defined as an article containing original data collected from one or more low or middle-income countries, as defined by the World Bank criteria. We also compared our findings with the similar reviews of the periods 2002–2004 and 1996–1998
Results
Our search identified a total of 3791 research articles; less than 7% (n = 259) were from low and middle-income countries. The three European journals published more articles from LAMI countries than the three American journals. Compared with the findings of a similar review of the period 1996–1998 and 2002–2004, there has been little change. The British Journal of Psychiatry and Acta Psychiatrica Scandinavica provided the major contribution from the LAMI countries of 8.7% and 9.6% respectively.
Conclusion
It is interesting that almost all journals describe themselves as International; however, our findings clearly suggest that there is a nine-to-one rule with most of the articles coming from richer countries. We suggest that there is a need to break the barriers, so that there should be no more under-representation of research from LAMI countries; which will lead towards the development of a truly international psychiatry.
To review current practice of lipid monitoring for patients prescribed colzapine and to improve the health of patients taking clozapine.
Methodology
This was a retrospective audit targeting all patients who were taking Clozapine from May 2008 to April 2009 inclusive. Data was collected from pharmacy records, the heath centre records and patients’ personal care records. Current practice within the hospital was then compared with the standards proposed by the Maudsley Guidelines.
Results
The total number of patients who were prescribed clozapine between May 2008 to April 2009 was 65. Of these patients 54 met the identified standards. We identified two patient groups; 56 patients were taking clozpaine for more than one year and nine patients were taking clozapine for less than one year. Out of those patients who were taking clozapine for more than one year, standards were met for 89% of patient (n = 50) compared to only 44% (n = 9) of those patients who were taking it for less than 1 year. Also, of those patients who had been taking clozapine for less than one year and do not meet the standard, none of them had lipid monitoring at three monthly intervals.
Conclusion
Although the vast majority of patients in the hospital who were prescribed Clozapine had their lipids monitored appropriately, a small percentage did not. Monitoring of lipid levels was particularly lacking in the first year of treatment.
To review current practice of Antipsychotics prescribing in patients with Behavioural and Psychiatric symptoms of Dementia in secondary care hospital.
Methodology
This was a retrospective audit targeting all patients who were diagnosed with a dementing illness in a large secondary care hospital from September 2008 to December 2008 inclusive. Data was collected from patients’ health care records and central computer database. Current practice was then compared with the standards proposed by the NICE Guidelines (National Institute of Clinical Excellence, 2006).
Results
Out of 18 patients who were diagnosed with dementia, 66% (n = 12) were prescribed antipsychotics. Out of these, 66%(n = 8) were males and 34%(n = 4) were females. 75%(n = 9) had explicitly documented indications for antipsychotics use in their health care records with only 25% cases (n = 3) alternative treatment options such as psychosocial interventions were considered.
Discussions
with patients and/or the carers’ were documented in 50%(n=6) cases. Periodic reviews were carried out in 66% (n = 8) cases.
Conclusion
Antipsychotics are commonly used in behavioural and psychiatric symptoms of dementia. Considering higher risk of morbidity and mortality with antipsychotics use in this population group, it is of paramount importance that reasons for prescribing and discussion with patients and/or their carers should be clearly documented. If antipsychotics are prescribed patients should be reviewed on regular basis.
Poor oral health can have a serious impact on quality of life, social inclusion and self-esteem. There is evidence to suggest that people with serious mental illness have a greater risk of experiencing oral disease and have greater oral treatment needs than the general population. Oral health problems are not well recognized by mental health professionals. We therefore conducted a retrospective study to review oral health care monitoring within the community mental health team.
Aims and objectives
To review the oral health care monitoring for patients accessing the community mental health team.
Methodology
Audit tool was developed based on oral health care guidelines outlined by the department of health, and literature review. We then retrospectively review medical records of 25 patients against following standards:.
– every client should have the most basic of oral hygiene equipment–toothbrush;
– clients should have basic oral hygiene knowledge, (i.e. brush twice or at least once a day);
– every client should be registered to a dental practitioner;
– every client should have at least one dental check-up per year;
– clients with dentures should have their dentures checked up at least once in five years;
– have a tooth brush less than three months old.
Results
Out of the 25 patients none had met the standards. It could be a reflection of lack of documentation rather than not providing appropriate information.
Conclusion
Oral health care advice should be part of care plan for people accessing mental health service.

Background: Previous studies have shown varied results with respect to the diagnostic utility of a positive nerve root sedimentation sign (SedSign) on MRI for symptomatic lumbar stenosis. The objective of this study was to analyze the clinical characteristics of SedSign utilizing a validated classification for low back and leg pain (Saskatchewan Spine Pathway classification; SSPc). Methods: This was a retrospective review of prospectively-collected data in 367 consecutive adult patients presenting to a spine surgeon with back and/or leg pain between January 1, 2012 and May 31, 2018. Inter- and intra-rater reliability for SedSign was 73% and 91%, respectively (3 examiners). Results: SedSign was positive in 111 (30.2%) and negative in 256 (69.8%) of patients. On the univariate analysis, a positive SedSign was correlated with age, male sex, several components of ODI, EQ5D mobility, cross-sectional area (CSA) of stenosis, and SSPc pattern 4 (intermitted leg dominant pain). On multivariate analysis, SedSign was associated with age, male sex, CSA stenosis and ODI sub-score for walking distance. The sensitivity and specificity of SedSign for neurogenic claudication was 50.3 and 82.9, respectively (positive predictive value 65.8%, negative predictive value 71.9%). Conclusions: The SedSign has high specificity for neurogenic claudication, but the sensitivity is poor.
Background: The nerve root sedimentation sign (SedSign) has been correlated with clinically significant lumbar spinal stenosis (LSS), and promoted as a possible prognostic indicator. However, diagnostic methods were not clearly defined in prior reports. In this study, the clinically validated Saskatchewan Spine Pathway enabled diagnosis of neurogenic claudication due to LSS. The objective was to compare the outcome of lumbar laminectomy for neurogenic claudication with respect to SedSign. Methods: This was a retrospective analysis of prospectively-collected data in patients with neurogenic claudication who underwent lumbar laminectomy. Outcome measures included Oswestry Disability Index, Visual Analogue Scale (VAS) for back and leg pain, and EuroQol 5-Dimension questionnaire. Results: Laminectomy was performed in 106 patients, and 60 were SedSign positive. Outcomes did not differ with respect to SedSign for all outcome measures, in non-instrumented and instrumented cohorts. Improvement in walking distance was associated with dural cross-sectional area of stenosis (p=0.02). VAS back and leg improvements were associated with back dominant (p=0.038) and leg dominant (p=0.0036) pain. Conclusions: This is the largest analysis of SedSign with respect to operative outcomes, and the only study with validated criteria for defining neurogenic claudication. Although other radiological and clinical factors are associated with improvements, SedSign did not correlate with laminectomy outcome.
