Dyadic coping strategies and quality of care experience: An original study of patients living with multiple sclerosis and their caregivers.

BACKGROUND AND OBJECTIVE: Multiple sclerosis has a major impact on the lives of patients and their caregivers. Measuring their experience is essential for improving the quality of care. Based on a sample of patient-informal caregiver dyads we examine whether coping strategies they implemented influenced their self-experience of quality of care. METHODS: One hundred and eighty three dyads were involved in this cross-sectional study. Self reported data included experience with the quality of care (Musicare) and coping strategies (Brief Cope) for patients and their caregivers. An actor-partner interdependence model (APIM) analysis was performed to assess the dyadic effects of coping strategies on experience of quality of care. RESULTS: Positive coping strategies were the most used by patients and caregivers alike. They were associated with a better experience of relationships with healthcare professionals, information about the disease and patient reception at the sites providing care. APIM analyses confirmed most of these results and identified one "partner" effect. CONCLUSION: The experience of the quality of the care of patients living with MS is related to the use of positive coping strategies.

CRISPR-Based Detection, Identification and Typing of Mycobacterium tuberculosis Complex Lineages.

The polymerase chain reaction (PCR)-based detection of Mycobacterium tuberculosis (M. tuberculosis) complex (MTC) in clinical samples is a first-line approach by which to diagnose tuberculosis in clinical microbiology laboratories. In this study, the genome-wide profiling of 3,156 mycobacterial genomes using Roary determined the CRISPR-csm4 gene as specific for MTB. Real time (RT)-PCR and the PCR-sequencing of CRISPR-csm4, tested on a collection of 20 MTC and 5 nontuberculous mycobacteria, confirmed the 20 MTC isolates, whereas the 5 nontuberculous isolates were not detected. Further, 65 of the leftover clinical samples, including 25 GeneXpert-positive and 40 GeneXpert-negative samples, that were used to evaluate the CRISPR-csm4-MTB assay in the clinical microbiology laboratory setting yielded expected results in every case, further allowing for the identification of the M. tuberculosis Beijing lineage. RT-PCR and the PCR-sequencing of CRISPR-csm4 could be implanted in the clinical microbiology laboratory to complement the currently used assays, with the potential of increasing the specification of the MTC pathogens responsible for tuberculosis. IMPORTANCE The whole-genome sequence comparison of the Mycobacterium tuberculosis complex (MTC) genomic sequences that are available in the NCBI database identified a unique, specific gene to be used directly on clinical diagnostic samples to detect MTC against all species of mycobacteria and to differentiate between MTC species, lineages, and sublineages.

%TTD and %TUDD: New SAS macro programs to calculate the survival data of the time to deterioration for patient-reported outcomes data in oncology.

BACKGROUND AND OBJECTIVE: Longitudinal analysis of patient-reported outcome (PRO) data remains challenging, as no standardization of statistical methods has been proposed, making comparison of PRO results between clinical trials difficult. In this context, the time to deterioration approach has recently been proposed and is regularly used as a modality of longitudinal PRO analysis in oncology. METHODS: Two new SAS macro programs were developed, %TTD and %TUDD, which implement longitudinal analysis of PRO data according to the time to deterioration approach. These programs implement the recommended deterioration definitions. We described the programs with their different functionalities. RESULTS: The %TTD macro calculates the time to first or transient deterioration, and the %TUDD macro calculates the time until definitive deterioration. These macros allow to obtain the survival variables from the time to deterioration approach. We illustrate our programs by presenting different applications on the randomized phase II AFUGEM GERCOR clinical trial. CONCLUSION: The implementation of the deterioration definitions in SAS software allows the dissemination of this approach, in order to move toward the goal of standardization of longitudinal PRO analysis in oncology clinical trials.

Molecular detection of Mycobacterium tuberculosis sensu stricto in the soil of Niger.

Mycobacterium tuberculosis (MTB) complex is comprising of pathogenic mycobacteria responsible for human and animal tuberculosis, a major public health problem in Niger. Although infected individuals are paramount sources of contamination, nevertheless alternative, neglected sources may play some role in minority forms of the infection. Accordingly, we investigated the presence of Mycobacterium tuberculosis complex in soil samples in Niger. A total of 103 soil samples were collected in six different areas in Niger in October and November 2018 and April and May 2020 from residential areas of tuberculosis patients. Screening PCR targeting M. tuberculosis complex CRISPR-Csm4 and Xpert MTB/RIF Ultra assay were applied to detect the M. tuberculosis complex. M. tuberculosis DNA was positively detected in five of 103 (5/103; 4.8%) soil samples (Dosso: one sample, Zinder: one sample and Niamey: three samples) using the CRISPR-Csm4 system. CRISPR-Csm4 gene sequence identified four M. tuberculosis sensu stricto (may be lineages 1, 3 or 4) and one M. tuberculosis L2 lineage (Beijing). Moreover, the five positive samples were confirmed by Xpert MTB/RIF Ultra assay as rifampicin-susceptible M. tuberculosis complex strains. However, culture remained negative after 42 days. In this study, we announced for the first time the presence of M. tuberculosis sensu stricto in the soil of Niger. Moreover, these detected lineages were identical to the dominant M. tuberculosis lineages in patients. The presence of common lineages of M. tuberculosis between the soil and human highlight the risk of transmission from the soil to human.

Time to deterioration in cancer randomized clinical trials for patient-reported outcomes data: a systematic review.

PURPOSE: The time to deterioration (TTD) approach has been proposed as a modality of longitudinal analysis of patient-reported outcomes (PROs) in cancer randomized clinical trials (RCTs). The objective of this study was to perform a systematic review of how the TTD approach has been used in phase III RCTs to analyze longitudinal PRO data. METHODS: A systematic literature search was conducted in PubMed/MEDLINE, the Cochrane Library and through manual search to identify studies published between January 2014 and June 2018. All phase III cancer RCTs including a PRO endpoint using the TTD approach were considered. We collected general information about the study, PRO assessment and the TTD approach, such as the event definition, the choice of reference score and whether the deterioration was definitive or not. RESULTS: A total of 1549 articles were screened, and 39 studies were finally identified as relevant according to predefined criteria. Among these 39 studies, 36 (92.3%) were in advanced and/or metastatic cancer. Several different deterioration definitions were used in RCTs, 10 studies (25.6%) defined the deterioration as "definitive", corresponding to a deterioration maintained over time until the last PRO assessment available for each patient. The baseline score was explicitly stated as the reference score to qualify the deterioration for most studies (n = 31, 79.5%). CONCLUSION: This review highlights the lack of standardization of the TTD approach for the analysis of PRO data in RCTs. Special attention should be paid to the definition of "deterioration", and this should be based on the specific cancer setting.

Study of gene expression alteration in male androgenetic alopecia: evidence of predominant molecular signalling pathways.

BACKGROUND: Male androgenetic alopecia (AGA) is the most common form of hair loss in men. It is characterized by a distinct pattern of progressive hair loss starting from the frontal area and the vertex of the scalp. Although several genetic risk loci have been identified, relevant genes for AGA remain to be defined. OBJECTIVES: To identify biomarkers associated with AGA. METHODS: Molecular biomarkers associated with premature AGA were identified through gene expression analysis using cDNA generated from scalp vertex biopsies of hairless or bald men with premature AGA, and healthy volunteers. RESULTS: This monocentric study reveals that genes encoding mast cell granule enzymes, inflammatory mediators and immunoglobulin-associated immune mediators were significantly overexpressed in AGA. In contrast, underexpressed genes appear to be associated with the Wnt/ß-catenin and bone morphogenic protein/transforming growth factor-ß signalling pathways. Although involvement of these pathways in hair follicle regeneration is well described, functional interpretation of the transcriptomic data highlights different events that account for their inhibition. In particular, one of these events depends on the dysregulated expression of proopiomelanocortin, as confirmed by polymerase chain reaction and immunohistochemistry. In addition, lower expression of CYP27B1 in patients with AGA supports the notion that changes in vitamin D metabolism contributes to hair loss. CONCLUSIONS: This study provides compelling evidence for distinct molecular events contributing to alopecia that may pave the way for new therapeutic approaches.

Emotional intelligence and coping strategies as determinants of quality of life in depressed patient-caregiver dyads: An actor-partner interdependence analysis.

OBJECTIVE: Patients with major depressive disorder (MDD) and their natural caregivers experience major lifestyle difficulties. Little is known concerning dyadic (i.e., patient and natural caregiver) characteristics' impact on quality of life. In a sample of depressed patient-caregiver dyads, we examined quality of life (QoL) levels compared with the general population and whether QoL is influenced by emotional intelligence (EI) and coping strategies using the actor-partner interdependence model (APIM). METHODS: This cross-sectional study involved 79 patient-caregiver dyads. The self-reported data, completed by patients and their primary caregivers, included QoL (SF-36), EI (TEIQue-SF) and coping strategies (BriefCope). The QoL of patients and caregivers was compared with 158 French age-sex-matched healthy controls. The dyadic interactions were analyzed using structural equation modeling. RESULTS: Patients and their caregivers experienced lower QoL levels than French age-sex-matched controls. The EI findings showed actor (degree to which the person's EI was associated with his/her own QoL) and partner (degree to which the person's EI was associated with QoL of the other member of the dyad) effects for patients and caregivers. The coping strategies (i.e., problem solving, positive thinking, avoidance and social support) revealed only actor effects. CONCLUSION: QoL is seriously impaired in depressed patients and their primary caregivers and is associated with EI and coping strategies. Targeted interventions focusing on EI and coping strategies could be offered to improve QoL in dyads.

Coping with a newly diagnosed high-grade glioma: patient-caregiver dyad effects on quality of life.

Patients with high-grade gliomas (HGG) and their caregivers have to confront a very aggressive disease that produces major lifestyle disruptions. There is an interest in studying the ability of patients and their caregivers to cope with the difficulties that affect quality of life (QoL). We examine, in a sample of patient-caregiver dyads in the specific context of newly diagnosed cases of HGG, whether the QoL of patients and caregivers is influenced by the coping processes they and their relatives use from a specific actor-partner interdependence model (APIM). This cross-sectional study involved 42 dyads with patients having recent diagnoses of HGG and assessed in the time-frame between diagnosis and treatment initiation. The self-reported data included QoL (Patient-Generated Index, EORTC QLQ-C30, and CareGiver Oncology QoL), emotional status, and coping strategies (BriefCope). The APIM was used to test the dyadic effects of coping strategies on QoL. Coping strategies, such as social support, avoidance, and problem solving, exhibited evidence of either an actor effect (degree to which the individual's coping strategies are associated with their own QoL) or partner effect (degree to which the individual's coping strategies are associated with the QoL of the other member of the dyad) for patients or caregivers. For positive-thinking coping strategies, actor and partner effect were not observed. This study emphasizes that the QoL for patients and their caregivers was directly related to the coping strategies they used. This finding suggests that targeted interventions should be offered to help patients and their relatives to implement more effective coping strategies.

[Health-related quality of life in patients treated for ovarian cancer: tools and issues]. / Étude de la qualité de vie dans les néoplasies ovariennes : outils et enjeux.

Health-related quality of life (QoL) in patients treated for ovarian cancer is directly and heavily impacted by the natural history of cancer, its evolution and its therapeutic modalities. The evaluation and consideration of various parameters of QoL seems to be a major issue. Indeed, on the one hand, it is essential to take into account the opinion of patients in the choice of therapeutic strategies for this cancer with a poor prognosis and, on the other hand, more and more studies show that QoL is an independent prognostic factor in ovarian cancer. Improvement in this case, in addition to being an endpoint by itself, would potentially improve the overall survival of patients. To date there are several tools to assess QOL of patients with ovarian cancer. The 2 questionnaires most commonly used are: FACT-O and the EORTC QLQ-OV28. The aim of our study was to evaluate from a review of the literature, the reciprocal effects of ovarian cancer on QoL and QoL on ovarian cancer survival, as well as specificities of each of the 2 questionnaires most commonly used in assessing the QoL.

A lipohydroxyacid-containing shampoo improves scalp condition and quality of life in patients with seborrheic dermatitis and light-to-moderate scalp psoriasis.

BACKGROUND: Dandruff is a common scalp disorder affecting almost half of the post-pubertal population of any ethnicity and both genders. It is one of the major reasons for patients to consult a dermatologist and it is the cause of significant psychological and social distress. AIMS: The aim of this open study was to evaluate the benefit of a 4-week treatment with a shampoo containing 0.1% lipohydroxyacid (LHA) and 1.3% salicylic acid on the scalp condition and on the quality of life of 275 volunteers with seborrheic dermatitis (SD) (n = 226) or light-to-moderate scalp psoriasis (SP) (n = 49). METHODS: The clinical benefit of the treatment was assessed by scoring the following parameters, i.e., severity of the dermatosis, scaling, itching, excoriations, and superficial burning sensation. The impact on the quality of life was assessed using the Scalpdex, a questionnaire specially developed by Chen et al. for patients with scalp dermatitis, which includes 23 questions regarding the symptoms, functioning and emotions affected by scalp dermatosis. RESULTS: The shampoo used in this study was well tolerated. After a 4-week treatment, dermatologists noticed a significant clinical improvement of all the scalp parameters evaluated (i.e., the composite lesional score was improved in 91% and 77% of the patients with SD or SP respectively). The symptoms, functioning and emotions scores of quality of life were also significantly improved in relation to the improvement of scalp condition. CONCLUSION: This study not only allowed a better understanding of the SD and SP patient's profile but also demonstrated that the shampoo evaluated is a convenient, efficient, safe, and well-tolerated cosmetic treatment of SD and light-to-moderate SP improving greatly the quality of life of the treated patients.

[Primary epiploic appendicitis: CT diagnosis for conservative treatment]. / Les appendicites épiploïques primitives: diagnostic tomodensitométrique pour un traitement conservateur.

OBJECTIVE: Primary epiploic appendicitis is an uncommon, self-limited disease with spontaneous resolution. Diagnosis is usually made at surgery as the disease is generally mistaken for acute appendicitis or sigmoid diverticulitis. CT allows a non-invasive diagnosis, thus avoiding unnecessary surgery. The condition can be managed conservatively with the use of analgesic drugs only, and clinical evolution is uneventful. The aim of this study is to report the CT features of this pathologic process before and after medical treatment by analgesics. PATIENTS AND METHOD: Six patients (4 men and 2 women aged from 23 to 70 year old mean; 29 year old) underwent abdominal CT scan because of acute abdominal pain located in the left lower quadrant (n = 3) and right lower quadrant (n = 3). No patient had fever. Laboratory findings were normal in all cases. Follow-up CT scans were obtained in 4 patients respectively at 2, 4, 8 and 80 weeks. RESULTS: CT scan showed in all cases a fatty mass located to the anterolateral wall of the colon, delineated by an hyper attenuating rim. Infiltration of the pericolic fat was noted in all cases. Follow up CT scans obtained in 4 patients showed that the inflammatory signs had cleared in all cases, the lesion had disappeared (n = 2), decreased in size (n = 1) or a residual paracolic node was observed (n = 1). CONCLUSION: Primary epiploic appendicitis is a rare disease. Knowledge of CT signs allowed the correct diagnosis and a conservative management.
