RESUMO

Background: Budgeting is the process resource allocation to produce the best output according to the revenue levels involved. Among the constraints that healthcare organizations, including hospitals, both in the public and private sectors, grapple with is budgetary constraints. Therefore, cost control and resource management should be considered in healthcare organizations under such circumstances. Methods: We aimed to identify methods of budgeting in healthcare systems and organizations as a systematic review. To extract and analyze the data, a form was designed by the researcher to define budgeting methods proposed in the literature and to identify their strengths, weaknesses, and dimensions. The search was conducted in Google Scholar, Web of science, Pub med and Scopus databases covering the period 1990-2022. Results: Overall, 33 articles were included in the study for extraction and final analysis. The study results were reported in four main themes: healthcare system budgeting, capital budgeting, global budgeting, and performance-based budgeting. Conclusion: Each budgeting approach has its own pros and cons and requires meeting certain requirements. These approaches are selected and implemented depending on each country's infrastructure and conditions as well as its organizations. These infrastructures need to be thoroughly examined before implementing any budgeting method, and then a budgeting method should be selected accordingly.

RESUMO

BACKGROUND AND AIM: Ultrasound-guided radiofrequency ablation (RFA) is a minimally invasive therapy for thyroid nodules (TNs). Understanding the determinants of RFA efficacy can improve treatment and prognosis. This study aims to investigate the relationship between ultrasound parameters of benign TNs and the efficacy of RFA. METHODS: A pretest-posttest interventional study was conducted in 2021 on 250 randomly sampled patients with benign TNs, receiving RFA. For this purpose, the volume reduction (VR) and the VR ratio (VRR) of the nodules were measured at the 1-, 3-, 6-, and 12-month follow-up periods after the RFA completion. The technical success rate (TSR) of this procedure was then categorized into four states, including low (VRR < 25%), moderate (VRR = 25-49%), high (VRR = 50-74%), and very high (VRR ≥ 75). Ordered logistic regression (OLR) was further utilized to investigate the effect of the ultrasound parameters of TNs on the TSR. The analyses were notably performed using Stata 14.2. RESULTS: The VRR at the 1-, 3-, 6-, and 12-month follow-up periods were 38.7%, 53.6%, 59.3%, and 59.9%, respectively. The mean VR was also statistically significant at all follow-ups (p < 0.001). At the 1-, 3-, and 6-month follow-up periods, the VR of over 50% was observed in 28.2%, 52.1%, and 65.2% of the nodules, respectively. The odds ratios (ORs) of the RFA success were found to be 4.3 times higher for the nodules in the left lobe compared to the right lobe (OR: 4.31, p = 0.002), 6.3 times greater for isoechoic nodules compared to hyperechoic nodules (OR: 6.39, p < 0.001), 6.2 times higher for hyper-vascular nodules compared to hypo-vascular nodules (OR: 6.25, p = 0.005), and 2.3 times greater for mixed nodules compared to solid ones (OR: 2.37, p = 0.049). CONCLUSION: The ultrasound parameters of TNs had a statistically significant effect on the efficacy of RFA. Small-sized, isoechoic, and hyper-vascular nodules, as well as those with mixed tissue, were observed to respond better to RFA, leading to a better prognosis in terms of VR after treatment.

RESUMO

BACKGROUND: Misdiagnosis is still an obstacle in the workup of polycystic ovary syndrome. We compared patients' characteristics among phenotypes of the syndrome and assessed the association of the characteristics with oligo-anovulation, hyperandrogenism, and polycystic ovary. METHODS: In the infertility department of a teaching hospital, we performed a cross-sectional study. Based on the Rotterdam criteria, we included 136 patients with polycystic ovary syndrome and 46 healthy controls. RESULTS: The most common phenotype was A (N=45;33%). Overall, A and C had larger body mass index (P=0.019 and 0.030, respectively) and waist circumference (P=0.005 and 0.003) than control. Also, A and D had higher serum anti-mullerian hormone than control (both P<0.001) or phenotype C (P<0.001 and =0.01). Phenotypes A and C had higher insulin than control (both P=0.004). The highest level of estradiol was for control and the lowest for B. The lowest high-density lipoprotein was for C; and A to C phenotypes had higher triglyceride than control (P=0.002, <0.001, and =0.041). Larger body mass was associated with hyperandrogenism [adjusted odds ratio (95% CI) =1.11(1.01, 1.23), P=0.034]; higher anti-mullerian hormone and high-density lipoprotein were related to oligo-anovulation [1.2(1.07,1.37), P=0.004; 1.1(1.00,1.13), P=0.041]. Higher insulin and lower high-density lipoprotein were associated with polycystic ovary [1.11(1.03,1.21), P=0.013; 0.9(0.82,0.97), P=0.014]. CONCLUSIONS: There are potentials in body mass index, waist circumference, serum anti-mullerian hormone, insulin, estradiol, high-density lipoprotein, and triglyceride concentration for differentiating the phenotypes of polycystic ovary syndrome and for more precise diagnosis of hyperandrogenism, oligo-anovulation, and polycystic ovary morphology.

RESUMO

A novel series of N-phenylacetamide-oxindole-thiosemicarbazide hybrids were synthesized and evaluated for their tyrosinase inhibitory activity. According to tyrosinase inhibition results, all the synthesized compounds showed high tyrosinase inhibitory activity with IC50 values ranging from 0.8 to 3.88 µM in comparison to positive control kojic acid with IC50 value of 36.32 µM. Among tested compounds, analog 7o, containing the 2-methyl-4-nitrophenyl on N-phenylacetamide moiety displayed superior tyrosinase inhibition. This compound was around 45-fold more potent than kojic acid. The kinetic analysis of compound 7o demonstrated that this compound is a competitive inhibitor against tyrosinase. Docking study of this compound demonstrated that compound 7o interacted with critical histidine residues within tyrosinase active site.
