Assessing the effects of violence on women in battering relationships with the Keane MMPI-PTSD Scale

The Minnesota Multiphasic Personality Inventory (MMPI)-Keane Posttraumatic Stress Disorder (PTSD) Scale (PK) has proven to be a reliable and valid measure of PTSD in combat veterans. However, few studies have examined the scale's validity in battered women, who often present with PTSD. Using empirically derived cutoff scores for the PK Scale, 69 battered women were assigned to PTSD-Positive and PTSD-Negative groups and then compared on measures of PTSD, distress, social support, and history of abuse in and out of the battering relationship. The PTSD-Positive group scored significantly higher across all measures of PTSD and distress, supporting the concurrent validity of the PK Scale in this population. However, the two groups differed only for the frequency of death threats, suggesting that the PK Scale is only mildly sensitive to the level of trauma exposure. Finally, lower levels of perceived social support were found in the PTSD-Positive than the PTSD-Negative group. Implications of these findings for the assessment of PTSD in battered women are discussed.     

The ubiquitin-proteasome system and inflammatory activity in diabetic atherosclerotic plaques: effects of rosiglitazone treatment

The role of ubiquitin-proteasome system in the accelerated atherosclerotic progression of diabetic patients is unclear. We evaluated ubiquitin-proteasome activity in carotid plaques of asymptomatic diabetic and nondiabetic patients, as well as the effect of rosiglitazone, a peroxisome proliferator-activated receptor (PPAR)-gamma activator, in diabetic plaques. Plaques were obtained from 46 type 2 diabetic and 30 nondiabetic patients undergoing carotid endarterectomy. Diabetic patients received 8 mg rosiglitazone (n = 23) or placebo (n = 23) for 4 months before scheduled endarterectomy. Plaques were analyzed for macrophages (CD68), T-cells (CD3), inflammatory cells (HLA-DR), ubiquitin, proteasome 20S activity, nuclear factor (NF)-kappaB, inhibitor of kappaB (IkappaB)-beta, tumor necrosis factor (TNF)-alpha, nitrotyrosine, matrix metalloproteinase (MMP)-9, and collagen content (immunohistochemistry and enzyme-linked immunosorbent assay). Compared with nondiabetic plaques, diabetic plaques had more macrophages, T-cells, and HLA-DR+ cells (P < 0.001); more ubiquitin, proteasome 20S activity (TNF-alpha), and NF-kappaB (P < 0.001); and more markers of oxidative stress (nitrotyrosine and O2(-) production) and MMP-9 (P < 0.01), along with a lesser collagen content and IkappaB-beta levels (P < 0.001). Compared with placebo-treated plaques, rosiglitazone-treated diabetic plaques presented less inflammatory cells (P < 0.01); less ubiquitin, proteasome 20S, TNF-alpha, and NF-kappaB (P < 0.01); less nitrotyrosine and superoxide anion production (P < 0.01); and greater collagen content (P < 0.01), indicating a more stable plaque phenotype. Similar findings were obtained in circulating monocytes obtained from the two groups of diabetic patients and cultured in the presence or absence of rosiglitazone (7.0 micromol/l). Ubiquitin-proteasome over-activity is associated with enhanced inflammatory reaction and NF-kappaB expression in diabetic plaques. The inhibition of ubiquitin-proteasome activity in atherosclerotic lesions of diabetic patients by rosiglitazone is associated with morphological and compositional characteristics of a potential stable plaque phenotype, possibly by downregulating NF-kappaB-mediated inflammatory pathways.     

Brazilian Portuguese version of the Revised Fibromyalgia Impact Questionnaire (FIQR-Br): cross-cultural validation,reliability, and construct and structural validation

Purpose: This study aimed to culturally adapt and validate the Revised Fibromyalgia Impact Questionnaire (FIQR) to Brazilian Portuguese, by the use of analysis of internal consistency, reliability, and construct and structural validity.

Method: A total of 100 female patients with fibromyalgia participated in the validation process of the Brazilian Portuguese version of the FIQR (FIQR-Br).The intraclass correlation coefficient (ICC) was used for statistical analysis of reliability (test–retest), Cronbach’s alpha for internal consistency, Pearson’s rank correlation for construct validity, and confirmatory factor analysis (CFA) for structural validity.

Results: It was verified excellent levels of reliability, with ICC greater than 0.75 for all questions and domains of the FIQR-Br. For internal consistency, alpha values greater than 0.70 for the items and domains of the questionnaire were observed. Moderate (0.40?r?r?>?0.70) correlations were observed for the scores of domains and total score between the FIQR-Br and FIQ-Br. The structure of the three domains of the FIQR-Br was confirmed by CFA.

Conclusions: The results of this study suggest that that the FIQR-Br is a reliable and valid instrument for assessing fibromyalgia-related impact, and supports its use in clinical settings and research. The structure of the three domains of the FIQR-Br was also confirmed.

• Implications for Rehabilitation

• Fibromyalgia is a chronic musculoskeletal disorder characterized by widespread and diffuse pain, fatigue, sleep disturbances, and depression. The disease significantly impairs patients’ quality of life and can be highly disabling.

• To be used in multicenter research efforts, the Revised Fibromyalgia Impact Questionnaire (FIQR) must be cross-culturally validated and psychometrically tested. This paper will make available a new version of the FIQR-Br since another version already exists, but there are concerns about its measurement properties.

• The availability of an instrument adapted to and validated for Brazilian Portuguese may make it possible to reliably verify the effects of rehabilitation programs on disability from fibromyalgia.

• The FIQR-Br showed results comparable with other versions of the FIQR in other languages, thereby enabling comparison of effects of rehabilitation interventions on disability from fibromyalgia conducted in Brazil with results of studies carried out in other parts of the world.

     

Video-assisted thoracic surgery major pulmonary resections. Present experience.

OBJECTIVE: The purpose of this report is to review our experience of video-assisted thoracic surgery (VATS) major pulmonary resections. METHODS: From January 1993 to December 1999 we proposed VATS, for major pulmonary resections, with these indications: benign lesions and solitary metastases not removable by wedge resection and stage I non-small cell lung cancer (NSCLC). The maximum size of the lesion had to be less than 4 cm. RESULTS: There were 125 patients, 87 men and 38 women with a mean age of 62. We successfully performed VATS procedure in 112 cases (one hamartoma, one tubercoloma, 12 typical carcinoids, 11 metastases and 87 lung cancers), while in another 13 (10.4%) a conversion to open surgery was required. There were 108 lobectomies, three bilobectomies and one pneumonectomy. Out of the first three cases of NSCLC, in all patients mediastinal node sampling or lymphadenectomy was performed. We recorded 13 (11.6%) postoperative complications, one of which required re-operation (bleeding). In the 99 patients without complications, the mean postoperative stay was 5.8 days. In a mean follow-up period of 36 months with patients having lung cancer we achieved a 3-year survival rate of 85+/-9 and 90+/-8% when only the patients in Stage I were considered. CONCLUSIONS: We believe that VATS, in performing pulmonary lobectomy, is a safe and effective approach and it seems to give the same long-term results as open surgery. Now the main problems concern the indications that should be strictly respected and the conversion to thoracotomy which should be undertaken without hesitation when the anatomic or pathologic conditions are not favourable.     

Recent developments on dry eye disease treatment compounds

Dry eye syndrome is a common tears and ocular surface multifactorial disease, described by changes in the ocular surface epithelia related to reduced tears quantity and ocular surface sensitivity, leading to inflammatory reaction. Managing the eye inflammation proved helpful to patients with dry eye disease and current treatment is based on the use of topically applied artificial tear products/lubricants, tear retention management, stimulation of tear secretion and using anti-inflammatory drugs. In this article we revise the corresponding literature and patents assembling the new treatment approaches of novel and future pharmaceutical compounds destined for the dry eye disease treatment. The most frequent categories of compounds presented are secretagogues and anti-inflammatory drugs. These compounds are the research outcome of novel therapeutic strategies designed to reduce key inflammatory pathways and restore healthy tear film.     

Ectopic immature renal tissue: clues for diagnosis and management

Ectopic immature renal tissue has rarely been reported in literature, associated or not with teratoma. Its finding could be matter of concern, owing to the occasional possibility that Wilms tumor may develop in this setting. We report a 1-year-old male patient who underwent surgery for a sacral subcutaneous small teratoma with a prevalent component of immature renal tissue. The lesion appeared completely excised and, in absence of features of malignancy, only follow-up was suggested. The patient was alive and well 15 months postoperatively. Whenever ectopic immature renal tissue is detected, a proper histological interpretation is mandatory, in order to plan a suitable treatment of the patient. From an extensive analysis of cases reported in literature we draw some practical suggestions for the diagnosis and treatment of this rare condition.     

Efficacy of flash glucose monitoring in pregnant women with poorly controlled pregestational diabetes (FlashMom): A randomized pilot study

Background and aimsGood glycemic control is crucial to reduce the risk of adverse pregnancy outcomes. Our aim was to evaluate the efficacy of Flash Glucose Monitoring (FGM) on glucose control in women with pregestational diabetes.Methods and resultsForty women with inadequately controlled type 1 (T1D, n = 34) and type 2 (T2D, n = 6) diabetes at conception were randomly assigned to two arms: the Flash Glucose group (FG, n = 21) using FGM, and the control group (CG, n = 19) using self-monitoring of blood glucose (SMBG). Glycated hemoglobin (HbA1c, %), time in (TIR), below (TBR) and above (TAR) range, glucose variability as well as the occurrence of maternal and neonatal adverse outcomes, were evaluated.HbA1c decreased significantly (p < 0.01) and similarly (?0.65 ± 0.7 vs. ?0.67 ± 0.8 for FG and CG, respectively; p = 0.89) in both groups during pregnancy. HbA1c reduction was positively associated with the number of daily FGM scans (p < 0.01). TBR (12.1 ± 2.0% vs. 19.6 ± 3.9%, p = 0.04) and the mean of the daily serum glucose difference (MODD) index (59.1 ± 5.4 vs. 77.7 ± 4.6, p = 0.02) were significantly lower in FG at second trimester. The rates of perinatal adverse outcomes were not different in the two studied groups.ConclusionsIn women with pregestational diabetes, FGM and SMBG had similar efficacy on glucose control during pregnancy. FGM showed additional advantages in terms of TBR and glucose variability. Achievement of good metabolic results depended on the adequate use of glucose sensor.RegistrationAt ClinicalTrials.gov as NCT04666818 on December 14, 2020.
