ABSTRACT

Psycho-education may have a positive effect on family caregivers of clients with mental disorders, and promote positive psychological states such as hope. The present study aims to investigate the effect of virtual social network-based psycho-education on the hope of family caregivers of clients with severe mental disorders. This study is a quasi-experimental research with a control and experimental groups. The participants of the study were 72 family caregivers of clients with severe mental disorders (36 in each group). Data were collected using demographic questionnaire and Adult Hope Scale before the study, immediately after the end of the training (first post-test), and 4 weeks afterwards (second post-test). The experimental group received psycho-education through Telegram App for four weeks. The results of the demographic questionnaire showed that both groups were homogeneous. The results of the Adult Hope Scale indicated that the mean score of both control and experimental groups were statistically significant and increased in the experimental group (P < 0.001). In addition, the changes of hope score in the experimental group were statistically significant in the first post-test than the pre-test, and in the second post-test than the first post-test and pre-test (P < 0.001). The findings of this study suggested that virtual social network-based psycho-education promotes the hopes of the family caregivers of clients with severe mental disorders. Due to the low cost and fast access of people to virtual networks, the content of this educational program can be widely used for family caregivers.

ABSTRACT

BACKGROUND: To determine whether there is an association between preoperative nutritional status and preoperative physical function, patient-reported quality of life, and body composition in colorectal cancer patients awaiting elective surgery.

METHODS: We conducted a pooled analysis of individual baseline patient data (n = 266) collected from 5 prehabilitation trials in colorectal cancer surgery. All data were collected approximately 4 weeks before surgery. Each patient’s nutritional status was evaluated using the Patient-Generated Subjective Global Assessment: scores 4-8 indicated need for nutritional treatment, whereas ≥9 indicated critical need for a nutrition intervention. Physical function was measured with the 6-minute walk test; patient-reported quality of life was captured with the SF-36; body mass and composition were determined using multifrequency bioelectrical impedance.

RESULTS: Mean Patient-Generated Subjective Global Assessment score was 5.3 (standard deviation: 3.9). Approximately two-thirds of patients had a Patient-Generated Subjective Global Assessment of 4-8 or ≥9 (n = 162/266). The 6-minute walk test was progressively worse with higher Patient-Generated Subjective Global Assessment scores (PG-SGA <4: 471(119) m; PG-SGA 4-8: 417(125) m; PG-SGA ≥9: 311(125) m, P < .001). Every component of the SF-36 was lower in those with a Patient-Generated Subjective Global Assessment ≥9 compared to Patient-Generated Subjective Global Assessment <4, indicating that malnourished patients suffer worse quality of life. Interestingly, only the male patients with a Patient-Generated Subjective Global Assessment ≥9 presented with statistically significant lower body mass, reduced fat-free mass index, and a lower percent body fat relative to those with Patient-Generated Subjective Global Assessment <4, in part due to the higher variability among the females.

CONCLUSION: The consequences of malnutrition are far-reaching and are strongly associated with the physical and mental health of colorectal cancer patients awaiting elective resection.

ABSTRACT

OBJECTIVE: This study aims to discuss the differential diagnosis value of endometrial volume and flow parameters in combination with serum carbohydrate antigen 125 (CA125) in endometrial benign and malignant lesions.

MATERIALS AND METHODS: The data of 250 patients with endometrial lesions were retrospectively analyzed. Carbohydrate antigen 125 (CA125) was determined before the operation. The morphology, hemodynamics, volume and flow parameters of the endometrium were measured by transvaginal three-dimensional-power Doppler angiography (3D-PDA). The endometrial volume (EV), 3D-PDA vascular index (VI), flow index (FI) and vascularization flow index (VFI) were calculated using the virtual organ computer-aided analysis software (VOCAL).

RESULTS: According to the pathological results, 202 patients (80.8%) had benign endometrial lesions and 48 patients (19.2%) had endometrial cancer (EC). The endometrium of EC patients was thicker (15.64 ± 7.26 mm vs. 9.24 ± 5.06 mm, P < 0.001), the endometrial volume was larger (9.23 ± 4.08 ml vs. 2.26 ± 3.42 ml, P < 0.001), and the flow parameters VI, FI and VFI were higher, when compared to those of benign lesions (P < 0.001). The area under the receiver operating characteristic curve (AUROCC) of VI receptors was 0.86, while the AUC of endometrial thickness (ET) was only 0.66. Therefore, the best variable for distinguishing benign and malignant endometrial lesions was VI. The level of CA125 in the EC group significantly increased (40.57 ± 17.45 vs. 17.87 ± 7.64, P < 0.001), and the level of CA125 increased (P < 0.05) with the increase in clinical grade, degree of tumor differentiation, and pelvic lymph node metastasis (P < 0.05). However, the difference in myometrial invasion was not statistically significant (P > 0.05).

CONCLUSION: Transvaginal 3D-PDA can clearly show the morphological and hemodynamic characteristics of endometrial lesions, and assist in the detection of EC in combination with serum CA125. This may have important clinical application value.

ABSTRACT

The microscopic explanation of the physical phenomena represented by a macroscopic theory is often cast in terms of the reduction of the latter to a more fundamental theory, which represents the same phenomena at the microscopic level, albeit in an idealized way. In particular, the reduction of thermodynamics to statistical mechanics is a much discussed case-study in philosophy of physics. Based on the Generalized Nagel-Schaffner model, the alleged reductive explanation would be accomplished if one finds a corrected version of classical thermodynamics that can be strictly derived from statistical mechanics. That is the sense in which, according to Callender (1999, 2001), one should not take thermodynamics too seriously. Arguably, the sought-after revision is given by statistical thermodynamics, intended as a macroscopic theory equipped with a probabilistic law of equilibrium fluctuations. The present paper aims to evaluate this proposal. The upshot is that, while statistical thermodynamics enables one to re-define equilibrium so as to agree with Boltzmann entropy, it does not provide a definitive solution to the problem of explaining macroscopic irreversibility from a microscopic point of view.

ABSTRACT

BACKGROUND: Nurses play a key role in identifying and supporting women with abusive experiences. However, research that evaluated the effectiveness of educational interventions on violence against women is sparse from India.

AIM: To evaluate the effectiveness of a training program in improving nurses’ knowledge and skills related to the identification and management of abused Women with Mental Illness (WMI).

METHODS: A randomized controlled trial design was adopted for the present study. A total of 68 nurses were randomly assigned to either the experimental or control group (34 in each group). The experimental group was provided eight interactive sessions based on a Nursing Module on abuse among women with mental illness. The assessments were done in both groups at baseline, after the intervention, at three months and six months. The data was collected using a self-rated questionnaire and case vignettes.

RESULTS: The mean knowledge score increased significantly in the experimental group after the intervention from 12.26 (SD, 2.03) to 23.60 (SD,1.24) and sustained at three months (23.07 ± 0.94) and six months (23.13 ± 1.61). Similarly, there were significant differences in nurses’ skills after the training program (t = 13.17, p < 0.001) and at different time points of assessment (p < 0.001).

CONCLUSIONS: Results showed that training had a positive impact on nurses’ knowledge and skills related to violence against women with mental illness. Therefore, it is necessary to provide continuous training on this issue to help nurses in providing holistic care to this vulnerable population.

ABSTRACT

This meta-analysis was performed to compare the efficacy and safety of dilatation and curettage (D&C) (simply D&C or combined with other treatments) and lesion resection for cesarean scar pregnancy (CSP). A search of English and Chinese databases from 2010 to 2019 was conducted. Thirty one studies were retrieved including sixteen random controlled and fifteen case controlled trials. Compared with abdominal resection surgery(ARS) and vaginal resection surgery(VRS), uterine artery embolization(UAE)+D&C has no obvious difference in curative effect and safety (UAE + D&C versus ARS: Cure rate(CR): P = 0.076, time for menstruation recovery/β-HCG normalization: P = 0.545/0.949,Blood loss: P = 0.005, adverse event: P = 0.420; versus VRS: CR: P = 0.085, time for menstruation recovery/β-HCG normalization: P < 0.001/P = 0.031,Blood loss: P = 0.902, adverse event: P = 0.249). UAE + D&C associated with lower blood loss and less postoperative complication than laparoscopic resection surgery(LRS), but LRS take more advantages in terms of the curative effect (CR: P = 0.047, time for menstruation recovery/β-HCG normalization: P = 0.352/0.103). The efficacy and safety of VRS are better than D&C, methotrexate (MTX) + D&C (D&C versus VRS: CR: P < 0.001, time for β-HCG normalization: P = 0.363,blood loss: P < 0.001, adverse event: P = 0.046; MTX + D&C versus VRS: CR: P < 0.001, time for menstruation recovery/β-HCG normalization: P < 0.001/P = 0.005, blood loss: P < 0.001, adverse event: P < 0.001). Lesion resection had advantages in shorter time for menstrual recovery/β-HCG normalization and less adverse events, lower failure rate over the administration of D&C treatments. In detail, the curative effect of UAE + D&C is similar to ARS and VRS, but inferior to LRS, while the safety of UAE + D&C is better than LRS. The efficacy and safety of simply D&C and MTX + D&C are not as good as VRS.

ABSTRACT

OBJECTIVE: There are few nationwide studies regarding the long-term analysis of cervical cancer patients in Taiwan. Thus, this study aimed to evaluate medical service utilization, and survival among cervical cancer patients initially diagnosed with or without anxiety and/or depressive disorders.

MATERIALS AND METHODS: This was a retrospective longitudinal study using data from the National Health Insurance Research Database from 1996 to 2010. The study subjects were cervical cancer patients identified by ICD-9-CM codes 180.X, while subjects with anxiety and/or depressive disorders were identified using the following codes: 300.0X-300.9X (minus 300.4X) for anxiety disorder, and 296.2X, 296.3X, 300.4, and 311.X for depressive disorder. The cervical patients with anxiety or/and depression disorder were classified as anxiety/depression (AD) group or the non-disorder (ND) group. Propensity score matching (PSM) was used to adjust for differences between the AD and ND groups. T-tests were used to evaluate differences in medical utilization and the Kaplan-Meier method was used to evaluate survival conditions between the two groups. Statistical analyses were performed using SPSS Statistics 20.0.

RESULTS: A total of 3664 patients were identified, with 862 (23.5%) having anxiety, 149 (4.1%) with depression, and 349 (9.5%) having both anxiety and depression. In total, 1360 cervical cancer patients had anxiety/depression disorders. After PSM, the AD group had significantly more outpatient department (OPD) visits than the ND group (p < 0.001) but the survival status was better in the AD group than the ND group (p < 0.001).

CONCLUSIONS: Cervical cancer patients with anxiety/depression disorders visited the OPD more frequently than those without anxiety/depression disorders but had better survival status. Gynecologists should also consider cancer patients’ mental status during follow-up, referring patients to psychiatric professionals for appropriate psychiatric care if appropriate.

ABSTRACT

OBJECTIVES: Women with polycystic ovary syndrome (PCOS) have an increased cardiometabolic risk. Similarly, it was previously shown that atherosclerotic and cardiovascular risk is increased in the general population with lower serum Klotho levels. The aim of this study was to investigate the lotho and thiol/disulfide levels in women with non-obese PCOS compared to healthy controls and also to investigate the relationship of serum Klotho and thiol/disulfide homeostasis with cardiometabolic risk factors.

MATERIALS AND METHODS: In this prospective case control study, human serum alpha Klotho levels and thiol/disulfide homeostasis of women with PCOS aged between 19-33 were compared to their age and BMI matched non – PCOS healthy controls. In addition, the correlation of these molecules with other metabolic markers/measurements were also investigated.

RESULTS: Metabolic parameters such as mean waist circumference, lipid accumulation product, visceral adiposity index, fasting insulin, homeostasis model assessment of insulin resistance and triglyceride values were higher in the PCOS group (p = 0.038, p = 0.008, p = 0.001, p = 0.001, p = 0.002 and p = 0.002, respectively) compared to controls. However, mean serum Klotho and native thiol levels (respectively p < 0.0001 and p = 0.038) were lower compared to controls. Correlation analysis revealed that serum Klotho levels were negatively correlated with BMI, waist circumference, disulphide/total thiol, disulphide/native thiol, HOMA-IR and LAP-index.

CONCLUSIONS: Findings of decreased serum Klotho and native thiol values of the PCOS group compared to controls and the negative correlation of serum Klotho levels with metabolic markers supports the idea that decreased Klotho may be another mechanism by which cardiovascular risk is increased in women with PCOS.

ABSTRACT

BACKGROUND: Platelet indices are used to evaluate platelet activation and function which change in inflammatory diseases. We hypothesise that platelet indices such as plateletcrit, mean platelet volume, and platelet distribution width may be more useful as prognostic indicators for myopericarditis in children.

METHODS: A total of 60 children were included in this study. Group 1 consists of children with myopericarditis, Group 2 is those with respiratory infections, and Group 3 consists of control group children of similar age and gender with the patient groups. Complete blood count parameters, C-reactive protein, and troponin values of the whole study group were recorded. Myopericarditis was diagnosed based on acute chest pain, dyspnea, palpitations, heart failure signs, arrhythmia symptoms and ST/T wave change, low voltage, supraventricular tachycardia/ventricular tachycardia on ECG, or elevated troponin T/troponin I levels or functional abnormalities on echocardiography. A comparison of the platelet indices made during diagnosis and 2 weeks after treatment was done for the myopericarditis patients.

RESULTS: There was no statistically significant difference in platelet indicies values. However, the increase in platelets and plateletcrit values after the treatment of myopericarditis was statistically significant. This study pointed out that there was a negative correlation between platelet-plateletcrit values and the troponin I-C-reactive protein.

CONCLUSION: We found that platelet count and plateletcrit values increased after treatment. This is important as it is the first study in children to investigate the possible role of platelet indications for myopericarditis in children.

ABSTRACT

Regulation of the transforming growth factor beta (TGFβ) superfamily by gonadotrophins in swine follicular cells is not fully understood. This study evaluated the expression of steroidogenic enzymes and members of the TGFβ superfamily in prepubertal gilts allocated to three treatments: 1200 IU eCG at D -3 (eCG); 1200 IU eCG at D -6 plus 500 IU hCG at D -3 (eCG + hCG); and the control, composed of untreated gilts. Blood samples and ovaries were collected at slaughter (D0) and follicular cells were recovered thereafter. Relative gene expression was determined by real-time PCR. Serum progesterone levels were greater in the eCG + hCG group compared with the other groups (P < 0.01). No differences were observed in the expression of BMP15, BMPR1A, BMPR2, FSHR, GDF9, LHCGR and TGFBR1 (P > 0.05). Gilts from the eCG group presented numerically greater mean expression of CYP11A1 mRNA than in the control group that approached statistical significance (P = 0.08) and greater expression of CYP19A1 than in both the eCG and the control groups (P < 0.05). Expression of BMPR1B was lower in the eCG + hCG treatment group compared with the control (P < 0.05). In conclusion, eCG treatment increased the relative expression of steroidogenic enzymes, whereas treatment with eCG + hCG increased serum progesterone levels. Although most of the evaluated TGFβ members were not regulated after gonadotrophin treatment, the downregulation of BMPR1B observed after treatment with eCG + hCG and suggests a role in luteinization regulation.
