ABSTRACT

Approximately one billion individuals suffer from mental health disorders, such as depression, bipolar disorder, schizophrenia, and anxiety. Mental health professionals use various assessment tools to detect and diagnose these disorders. However, these tools are complex, contain an excessive number of questions, and require a significant amount of time to administer, leading to low participation and completion rates. Additionally, the results obtained from these tools must be analyzed and interpreted manually by mental health professionals, which may yield inaccurate diagnoses. To this extent, this research utilizes advanced analytics and artificial intelligence to develop a decision support system (DSS) that can efficiently detect and diagnose various mental disorders. As part of the DSS development process, the Network Pattern Recognition (NEPAR) algorithm is first utilized to build the assessment tool and identify the questions that participants need to answer. Then, various machine learning models are trained using participants' answers to these questions and other historical data as inputs to predict the existence and the type of their mental disorder. The results show that the proposed DSS can automatically diagnose mental disorders using only 28 questions without any human input, to an accuracy level of 89%. Furthermore, the proposed mental disorder diagnostic tool has significantly fewer questions than its counterparts; hence, it provides higher participation and completion rates. Therefore, mental health professionals can use this proposed DSS and its accompanying assessment tool for improved clinical decision-making and diagnostic accuracy.

ABSTRACT

Singlet oxygen generated by photosensitization has limited potential in vivo due to light attenuation in tissues. However, controlled chemical generation of this reactive oxygen species is likely to open new therapeutic spaces to explore. The fact that its activity is limited by the rate of cycloreversion reaction and the diffusion distance of the excited state molecular oxygen species, is a clear advantage, considering the serious side effects of off-target anticoagulants. In this work, we present novel 1,4-naphthalene endoperoxides as potential anti-coagulant agents due to thermal release of singlet oxygen.

ABSTRACT

Precise spatiotemporal control of singlet oxygen generation is of immense importance considering its involvement in photodynamic therapy. In this work, we present a rational design for an endoperoxide which is highly stable at ambient temperatures yet, can rapidly be converted into a highly labile endoperoxide, thus releasing the "stored" singlet oxygen on demand. The "off-on" chemical switching from the stable to the labile form is accomplished by the reaction with fluoride ions. The potential utility of controlled singlet oxygen release was demonstrated in cell cultures.

ABSTRACT

Background/aim: The aim of the study was to investigate the effect of systemic sclerosis (SSc) on quality of life and sexual function in female patients. Materials and methods: The study included 30 sexually active female patients with SSc and 30 healthy control subjects. For all participants in both the patient and control groups, the female sexual index and SF-36 forms were completed and a detailed medical and sexual history was taken. Results: The mean age was 45.03 ± 9.22 years in the SSc group and 44.6 ± 11.52 years in the control group (P = 0.87). The SF-36 scores in the patient group were significantly lower than those in the control group. Sexual dysfunction was found in 26/30 (86.6%) of the SSc patients and in 6/30 (20%) of the control group (P = 0.0001). Significant differences were determined between the groups with respect to sexual desire, arousal, lubrication, orgasm, sexual satisfaction, and pain. There was no significant relationship between the subgroups of SSc patients, duration of disease, lung involvement, and FSFI scores. Conclusion: Sexual dysfunction and lower health quality are common problems in female patients with systemic sclerosis.

ABSTRACT

BACKGROUND/AIM: Acute pancreatitis is the most common adverse event of endoscopic retrograde cholangiopancreatography (ERCP). We aimed to evaluate the efficacy of intramuscular diclofenac sodium for prophylaxis of post-ERCP pancreatitis (PEP) in comparison to the rectal form. MATERIALS AND METHODS: One hundred and fifty consecutive patients who underwent ERCP were enrolled in this single-center, prospective, randomized controlled study. Patients were randomized into three groups. The first group received 75 mg of diclofenac sodium via intramuscular route and the second group received 100 mg of diclofenac sodium rectally 30-90 min before the procedure. The third group served as the control group. Patients were evaluated for post-ERCP pancreatitis with serum amylase levels and abdominal pain 24 h after the procedure. RESULTS: The overall incidence of PEP was 6% (n = 9) and 2% (n = 1) in the intramuscular (IM) and rectal groups, respectively, and 14% in the control group (P = 0.014). Nineteen (12.7%) patients developed post-ERCP abdominal pain (8% in IM, 10% in rectal, and 20% in control group; P = 0.154). Twenty-five (16.6%) patients developed post-ERCP hyperamylasemia (10% in IM, 12% in rectal, and 24% in control group; P = 0.03). CONCLUSION: Prophylaxis with diclofenac given rectally or intramuscularly is an effective option for the management of post-ERCP pancreatitis.

ABSTRACT

The most important cause of anemia in CKD is relative deficiency of erythropoietin (EPO) secretion from the diseased kidney and EPO therapy has become the standard treatment for anemia of CKD. However, some patients do not respond well to erythropoiesis stimulating agent (ESA), so-called ESA resistance. One of the most important causes of ESA resistance is chronic inflammation in hemodialysis (HD) patients. ESA hyporesponsiveness index (EHRI), calculated as the weekly dose of EPO divided by kilograms of body weight divided by the hemoglobin level, and has been considered useful to assess the EPO resistance. Neutrophil/lymphocyte (NLR) ratio and platelet/lymphocyte ratio (PLR) were also found to be associated with inflammation in HD patients. However, the relationship between NLR, PLR and EHRI has not been investigated before. HD patients underwent medical history taking, physical examination, calculation of dialysis adequacy and biochemical analysis and calculation of EHRI. Logarithmically converted EHRI (logEHRI) was correlated only with hemoglobin (r -0.381, P < 0.0001) and PLR (r = 0.227, P = 0.021) but not with NLR. Comparison of PLR among 25th, 50th and 75th percentile of EHRI showed that PLR levels increased going from the 25th to 75(th) percentile (P = 0.032). Posthoc analysis revealed that 25-75th percentile (P = 0.014) and 50-75th percentile (P = 0.033) were different with respect to PLR. In linear regression analysis, PLR (standardized ß = 0.296, confidence interval: 0.000-0.001, P = 0.003) was independently associated with logEHRI. We found that PLR was independently associated with EHRI in HD patients. PLR, which is quite a simple and cheap method, may guide clinicians for detecting EPO resistance.
