This study aimed to develop a predictive tool for identifying individuals with high antibody titers crucial for recruiting COVID-19 convalescent plasma (CCP) donors and to assess the quality and storage changes of CCP. A convenience sample of 110 plasma donors was recruited, of which 75 met the study criteria. Using univariate logistic regression and random forest, 6 significant factors were identified, leading to the development of a nomogram. Receiver operating characteristic curves, calibration plots, and decision curve analysis (DCA) evaluated the nomogram’s discrimination, calibration, and clinical utility. The nomogram indicated that females aged 18 to 26, blood type O, receiving 1 to 2 COVID-19 vaccine doses, experiencing 2 symptoms during infection, and donating plasma 41 to 150 days after symptom onset had higher likelihoods of high antibody titres. Nomogram’s AUC was 0.853 with good calibration. DCA showed clinical benefit within 9% ~ 90% thresholds. CCP quality was qualified, with stable antibody titres over 6 months (P > 0.05). These findings highlight developing predictive tools to identify suitable CCP donors and emphasize the stability of CCP quality over time, suggesting its potential for long-term storage.

Of the wildlife casualties admitted to rehabilitation centres in England, less than half are subsequently released back into the wild. If the factors associated with survival within rehabilitation centres can be determined, they may be used to focus efforts on individuals with high chances of successful recovery, and thus improve welfare by devoting resources to those animals that are more likely to benefit. We analysed the medical record cards of eight species admitted to four wildlife rehabilitation centres run by the Royal Society for the Prevention of Cruelty to Animals between 2000-2004 to determine those factors that affected the chance of survival in care until release, and whether trends in predictive factors occurred across taxonomic groups. We found that the most important predictive factor, across all species, was the severity of the symptoms of injury or illness. Factors commonly used as important indicators of rehabilitation success in published practice guidelines, such as mass and age, were not found to affect survival significantly. Our results highlight the importance of triage based on clinical diagnosis as soon as a wildlife casualty is admitted, and indicate that although the ethos of many rehabilitation centres is to attempt the treatment of all wildlife casualties, the attempted treatment of those with severe injuries may be adversely affecting welfare by prolonging suffering.

This paper reviews and presents data of practical impact for those administering electroconvulsive therapy (ECT). In the first section, physical and physiological aspects of the stimulus as well as methods of stimulation are discussed. The second section deals with indications for ECT, efficacy and treatment modalities such as seizure duration, treatment frequency and total number of ECT applications. The last section is devoted to side effects, risks, comedication and comorbidity.

This study aimed to investigate the psychological disorders following rape as well as the course of Post-Traumatic Stress Disorder (PTSD), and to determine clinical factors predictive of chronic PTSD. Seventy-three rape victims were observed in a systematic follow-up study over 1 year following rape using structured interview schedules. The frequency of PTSD was massive. The early disorders predicting PTSD 1 year after rape included somatoform and dissociative disorders, agoraphobia and specific phobias as well as depressive and gender identity disorders and alcohol abuse. Through stepwise logistic regressions, the following were found to be good models of prediction of chronic PTSD 1 year after rape: for the characteristics of the traumas, intrafamily rape, being physically assaulted outside rape, and added physical violence during rape; for the early psychological and behavioural attitudes, low self-esteem, permanent feelings of emptiness and running away; and for early mental disorders, agoraphobia and depressive disorders. Finally, among all these predictive factors, added physical violence during rape, low self-esteem, permanent feelings of emptiness and agoraphobia were shown to constitute a strong model of predictors. People presenting features such as the predictive factors of chronic PTSD found in the study should be asked about a history of rape and symptoms of PTSD.

Objective - The aim of the present paper is to assess the supply and demand of psychotherapy in mental health services and to identify the factors predicting the start of psychotherapy, using routine data, including 18 clinic and extraclinic variables, collected at 10 Mental Health Centers. Setting - Ten Mental Health Services of Regione Emilia-Romagna. Design - A prospective longitudinal study regarding all «new» users in 1995 followed for one year after the first visit. Results - The percentage of the new users starting a psychotherapy was 11.5%, corresponding to an overall one-year incidence of 5.6/10000 inhabitans ≥18 years old (range 0.9-14.8 across the 10 centres). The demand of psychotherapy in 1995 was 16.1%, including both the request of the patients and the primary care physicians (range 0.6-33%). The predictive factors for the beginning of the psychotherapy were: the presence of a psychologist at the first encounter, the request of the patient for a psychotherapy, age < 48 years, high educational level, being student, living with the family, the Mental Health Center; the broad diagnostic group of «neurotic» diagnoses resulted to have a twofold probability with respect to controls to start a psychotherapy. The logistic regression analysis of 18 variables coudn't find a predictive model with more than 33% sensitivity. Conclusions - The psychotherapeutic treatment is not predictable in the 10 Centers we studied, because of extreme differences in psychotherapy supply among Centers and probably because of uncertainty of therapeutic recommendations for psychotherapies.

Objectives: To identify predictive factors of complications occurring during paediatric interventional catheterisation. Background: Interventional paediatric catheterisation is still burdened by a substantial risk. Risk factors, however, have rarely been investigated. Methods: We analysed prospectively 1,022 interventional procedures performed over a period of 8 years, excluding 260 procedures for atrial septostomy. We considered several patient-related variables, specifically age, weight, and gender, type of procedure, times required for fluoroscopy and the overall procedure, technical challenge, and the severity of the clinical condition. We also analysed variables linked to the environment, specifically the date of the examination, whether the operator remained in training, the novelty of the material, any breakdown in the installation, and errors made by the operator. We classified complications as those without clinical consequence, those which proved lethal, those requiring cardiopulmonary resuscitation, elective or emergency surgery, hospitalisation in the intensive care unit, and those leading to recatheterisation. Results: Our average incidence of complications was 4.1 per cent, which did not change significantly during the period of study. Of the patients, 4 died, 7 needed urgent surgery, 5 elective surgery, 3 hospitalisation in intensive care unit, and 8 recatheterisation. Independent risk factors for complications were technical challenge, critical clinical condition, operator in training, operator error, and breakdown of the installation. Young age was not associated with a higher risk of complications. Patients in whom no cause for complication could be found, either related to their own features or the environment, had a risk of complication of 1.4 per cent (95 per cent confidence intervals from 0.7 to 2.5 per cent). Conclusions: Our data show that variables relating either to the patient or the environment of catheterisation are associated with an increased risk of procedural complications. Knowledge of the risk factors can improve the odds of paediatric interventional catheterisation.

Une étude longitudinale auprès de 327 adolescents scolarisés suivis de 16 à 18 ans a permis de mettre en évidence l’évolution de la consommation de drogue illicite et les facteurs liés à cet usage. Au total, à 18 ans, 26% des garçons et 16% des filles ont essayé la drogue au moins une fois dans leur vie, et respectivement 10 et 8% en ont pris urant plusieurs périodes de l’enquête. L’expérimentation d’une drogue illicite est peu corrélée aux variables socioemographiques de la famille, ce que traduit l’homogénéisation de la population qui en fait l’essai. En revanche, les jeunes consommateurs se caractérisent par un mode de vie centré sur les relations avec les pairs, mettant l’accent sur la sphère relationnelle au détriment des relations familiales et de l’intérêt pour leur scolarité. L’alcoolisation et le tabagisme précoce sont des facteurs prédictifs de l’usage (unique mais surtout répété) d’une drogue illicite. De même que le cumul des problèmes de santé (dépressivité, troubles du sommeil, troubles somatiques). Toutefois, pour l’ensemble e ces variables corrélées à l’essai d’une drogue illicite, une prédictivité différentielle selon le sexe est observée. La consultation médicale augmente après l’usage répété de drogue. Les jeunes expérimentateurs conservent un contact Privilégié avec leurs parents et avec les jeunes en cas de problèmes (scolaire, santé, sentimentaux, graves). Il est discuté a Place des parents, des adultes responsables (médecins, professionnels de la santé, enseignants) et des pairs dans une Prévention précoce des difficultés de l’adolescent.
