Good inventory management can plan, control, and manage the company's inventory to consumer demand. Poor inventory management has a significant impact on the company. Excess raw materials will affect high inventory costs, and a lack of raw materials will impact dissatisfied consumers. Therefore it is necessary to have a valid inventory policy. This research aims to minimize PT XYZ's inventory costs using the Continuous Review and Periodic Review methods. The research was conducted by taking data from PT XYZ and then doing ABC analysis, normality test, Continuous Review and Periodic Review methods, and sensitivity analysis. The results showed that the most optimal inventory policy for minimizing inventory costs is the continuous review method (s, S). The results of this study can be used as a reference in determining inventory policies to minimize costs.

Published: October 2022

Una preocupación constante a nivel mundial y para las organizaciones internacionales es la frecuencia de los casos de violencia intrafamiliar, por lo cual se han establecido políticas públicas con la finalidad de prevenir, sancionar, erradicar y finalmente proteger a las víctimas; en Ecuador han existido normativas que regulan los derechos de las dos partes durante el proceso penal, tanto al victimario como a la víctima, la participación activa de la parte ofendida siempre es importante dentro de estos procesos penales debe ser participativa, con la finalidad de evitar la impunidad, si esto no sucede, la determinación de la responsabilidad del agresor se dificulta por parte del sistema de administración de justicia; considerando este contexto, se plantea como objetivo: analizar desde el punto de vista crítico-jurídico la falta de participación activa de la víctima de violencia intrafamiliar al momento de determinar la responsabilidad del agresor; para dar respuesta al objeto de estudio se recurrirá a la investigación explicativa como método de investigación, y el paradigma cualitativo; los métodos teóricos a utilizar serán el método de análisis y síntesis, el método histórico, y el método exegético, mientras que los métodos empíricos a os cuales se recurrirá serán la encuesta; luego de encuestar a 25 mujeres víctimas de violencia intrafamiliar fue posible evidenciar que muchas de las mujeres que no quisieron responder tenían un menor nivel educativo, y que en su mayoría existe los abandono de procesos.

Objectives: This study was conducted to assess the predictive value of Shock Index-Creatinine Clearance (SI-C) for the risk stratification of contrast induced nephropathy (CIN) in patients after primary percutaneous coronary intervention (PPCI).
Methodology: 1150 consecutive patients of STEMI and candidates of PPCI presenting at our tertiary care cardiac center were included in this study. Patients with significant hemodynamic instability, allergic reaction to contrast agent or having exposure to contrast agent within a week prior to PPCI and those requiring renal replacement therapy were excluded from this study. SI-C and Mehran risk scores were calculated and the rise in post procedure serum creatinine level by 0.5 mg/dL or up to 25% from baseline was characterized as CIN. The predictive power of both SIC and Mehran risk score was assessed with help of receiver operating characteristic (ROC) curve analysis.
Results: Out of 1150 participants, 960 were male with a mean age of 55.64 ± 11.45 years. Out of which 113 (9.8%) patients developed CIN. Area under the cure (AUC) for the prediction of CIN was 0.702 [95% confidence interval (CI): 0.651 to 0.753] for SI-C as against 0.633 [95% CI: 0.574 to 0.692] for Mehran score. SIC also retained its statistical significance as independent predictor of CIN with adjusted odds ratio of 1.01 [95% CI: 1.01 to 1.02] on multivariable regression analysis.
Conclusion: SI-C has demonstrated strong discriminative power to determine the risk of CIN in PPCI setting when compared with Mehran risk score.

Objectives: This study was designed to compare the in-hospital outcomes of primary PCI with export vs. primary PCI with the balloon in patients with total occlusion.
Methodology: Consecutive patients with STEMI undergoing primary PCI with TA and pre-balloon dilatation were recruited in 1:1 ratio and post-procedure in-hospital mortality and complication rate (slow flow/no-reflow, contrast-induced nephropathy (CIN), and arrhythmias) were compared. Patients in the TA group were further stratified based on export time (time from onset of chest pain to the use of export) as ≤ 6 hours or > 6 hours.
Results: A total of 200:199 patients were recruited in export and balloon group. Overall complications were significantly higher in balloon group, 39.7% (79/199) vs. 23.0% (46/200); p<0.001, which included slow flow/no-reflow (24.6% vs. 14.5%; p=0.005), CIN (10.1% vs. 4.5%; p=0.022), and arrhythmias (14.6% vs. 5.5%; p=0.006) with in-hospital mortality rate of 3.0% (6/200) vs. 6.0% (12/199); p=0.153. Upon stratifications, outcomes were more favorable when export time was ≤ 6 hours as compared to > 6 hours with mortality rate of 0% vs. 6.3%; p=0.010 and complication rate of 19.2% vs. 27.1%; p=0.187.
Conclusion: TA in patients with total occlusion was associated with lesser complications and relatively better mortality benefits. The benefits of TA were directly associated with export time. Therefore, timely use of export can be considered in patients with total occlusion.

Impact of Celebrity Suicides on mental health of vulnerable population

Published: October 2022

Suicide is culminating into a grave public health concern. Approximately 800,000 people worldwide commit suicide annually, with 3/4th owing to low- middle-income countries.(1) In 2016, the suicide rate in India was 16.5, exceeding the global average of 10.5/1,00,000.(1) Suicide is the deliberate ending of one's own life(2) and primarily done due to persistent sense of despair, depression, drug misuse, and various personal and financial stress factors. One such trigger is suicide by an eminent figure, also known as werthering effect, modelling effect, or copycat suicide. This phenomenon commonly affects the adolescent and younger adults. In India, the 15-29 age group were found most vulnerable.(1) Nearly 5% of consecutive suicides occur after a celebrity death primarily among young, female, and unemployed without being prompted by adverse life circumstances.(3) Given the global gravity of suicide and India's contribution to it, it is critical to identify the psychopathology and risk factors behind it.
