Kata kunci: Kekeringan, Produktivitas Padi, Metode SPI Abstract. In Aceh Besar Regency, the majority of people still rely on rain-fed rice fields where the irrigation system relies heavily on rainfall so that rice production in this area is influenced by rainfall. Therefore, study onthe drought index using the SPI method in Aceh Besar Regency is needed. The SPI method was chosen because it has a flexible index and is simple to calculate. SPI can provide information about droughts that last for several months or even years, this makes it possible to understand the impact of long-term droughts and by monitoring SPI values it is possible to anticipate the potential for future droughts. The results of the analysis of the drought index calculation using the SPI method in Aceh Besar Regency show different levels of severity. The worst 1-month SPI incident occurred in 2020, namely -2.22, while the level of wetness occurred in 2014, namely 2.81. The worst 3-month SPI incident occurred in 2020, namely -2.37, while the wetness level occurred in 2020, namely 2.47. The worst incidence of the 6-month SPI occurred in 1998, namely -2.35, while the level of wetness occurred in 2014, namely 2.79. The worst incidence of the 12-month SPI occurred in 1998, namely -2.01, while the level of wetness occurred in 2011, namely 2.34. Keywords: Drought, Rice Productivity, SPI Method

Intravitreal ranibizumab injection very common in treatment of diabetic macular edema also helpful in decreasing the changes caused due to Diabetic Macular Edema, associated with different types of diabetes and works well in overall improvement of visual outcomes. To assess changes in macular thickness using OCT MACULA and intraocular pressure using a noncontact tonometer (NCT) before and after intravitreal ranibizumab injection in diabetic macular edema patients. : This was observational study done on 60 patients. The assessment of macular thickness changes done with the help of optical coherence tomography (OCT) and intraocular pressure monitored with non-contact tonometer (NCT) whereas visual acuity assessment was recorded with Snellen’s chart. Intravitreal injection of 1.25 mg of Ranibizumab was injected 3.5 mm from the limbus under topical anaesthetic drops. Post injection follow up was scheduled on 1st post procedure day and after one month. Post procedure Optical coherence tomography (OCT) was performed in all patients 1 week before and 1 month after 1st injection : Out of a total of 60 eyes, 38 patients had poor control of diabetes, whereas in 22 (64%) patients’ diabetes was under control with treatment. IOP recorded had a mean value of 17mmHg in 95% of cases and 5% had gone to higher side 30mmHg to 45mmHg. The mean Central Macular Thickness pre intravitreal Ranibizumab injection thickness was 385.40 ± 42.25 um. After giving injection, on the final visit after 1 month, the mean thickness had gradually decreased by 324.22 ± 33.55 um. 53patients out of 60 (88%) had Insulin Dependent Diabetic Mellitus whereas 7 cases (12%) had Non-Insulin Dependent Diabetic Mellitus : Ranibizumab intravitreal injection is effective in cases of DME. This is also effective to improve visual outcome. NPDR was most commonly found in Insulin Dependent Diabetic Mellitus and in cases of Proliferative diabetic Retinopathy -Non-Insulin Dependent Diabetic Mellitus was more commonly observed. Central macular thickness after 1 month of injection was reduced in 57 cases 95% whereas the visual acuity improvement also seen in these patients and increased. In 57 / 60 cases (95%) visual acuity was improved, In 2/60 (3.34%) visual acuity remained as it is and in 1/60 (1.66%). case it was decreased. In 95% of cases the IOP maintained under normal limits. In 5% cases it had gone to the higher side.

Sickle cell disease (SCD) is a prevalent genetic disorder marked by chronic hemolysis and vaso-occlusive events, leading to multiorgan complications, including significant ocular morbidity. This study aims to elucidate genotype-specific patterns and clinical implications of ocular morbidity in SCD patients at a tertiary healthcare center in western Odisha, India. A cross-sectional study was conducted at Veer Surendra Sai Institute of Medical Sciences and Research (VSSIMSAR), Burla, Sambalpur, Odisha, from November 2018 to October 2020. A total of 103 SCD patients were enrolled using convenience sampling. Detailed ocular examinations, including visual acuity assessment, anterior segment evaluation, fundoscopy, and additional imaging, were performed. Data were analyzed using SPSS to identify genotype-specific patterns of ocular morbidity. Of the 103 patients, 60 had HbSS and 43 had HbSC genotype. The overall prevalence of ocular manifestations was 76.6%, with HbSC patients showing a slightly higher prevalence (81.4%) compared to HbSS patients (73.3%). Conjunctival corkscrew vessels were significantly more prevalent in HbSC patients (p=0.041). No significant differences were found between genotypes for other anterior segment signs or non-proliferative and proliferative fundus signs. Our study reveals a high prevalence of ocular morbidity in SCD patients, with notable genotype-specific patterns. HbSC patients are more prone to certain ocular manifestations, underscoring the need for genotype-specific screening and management strategies. Early detection and targeted interventions can mitigate vision loss and improve patient outcomes.

Published: December 2024

A new study finds that in about 14-16% of macular hole repairs using the inverted internal limiting membrane (ILM) flap technique, the hole actually closes itself thanks to a thin layer of the ILM left behind, not the full flap itself. This suggests a potentially simpler closure mechanism for this surgery. This study was conducted to investigates both the physical results (anatomy) and vision improvements experienced by patients who underwent large macular hole surgery using the inverted internal limiting membrane (ILM) flap technique. : 20 patients with significant macular defects participated in the research from January 2019 to December 2019 at the Ispahani Islamia Eye Institute and Hospital. Idiopathic large macular lesions were analyzed in the study using optical coherence tomography (OCT) and biomicroscopy. Exclusion criteria excluded macular holes measuring less than 400 μm and those resulting from other etiologies. Demographic and clinical information was collected, including age, gender, best-corrected visual acuity (BCVA), and intraocular pressure. Slit-lamp biomicroscopy was performed on the anterior region and fundus, and spectral-domain optical coherence tomography (OCT) was used to verify the presence of macular holes. Approval from the institutional ethical committee was obtained, and surgical procedures were performed after informed consent. The final best-corrected visual acuity was documented, and a comprehensive ocular assessment was conducted during appointments. In this study half (50.0%) of patients belonged to those aged≥51 years. The mean age was 41.40±17.87 years with ranged from 20 to 60. Here it was observed that the mean BCVA pre-operative was 1.39±0.65 and the mean BCVA (3 months after surgery) was 0.50±0.16. In OCT all (100.0%) patients had macular holes before surgery and 100.0% closure of MH after surgery. Here ERM is formed in only 1(10.0%) patient. The study found a 100% closure rate for macular holes and superior functional outcomes. Further research is needed to assess the efficacy of this approach with a larger sample size and longer follow-up duration.

To compare efficacy of intrastromal Voriconazole as a primary treatment of deep seated fungal corneal ulcer versus conventional treatment in form of 5% topical Natamycinin Northern India. A prospective, hospital based, interventional study was done between Jan 2022 to Jan 2023 in all deep seated fungal corneal ulcers involving half or more of corneal stromal depth. A total 30 patients (15 patients in each group) were studied. Groups were comparable in terms of age, gender, laterality, causative organism and size and depth of infiltrate. Mean age in intrastromal Voriconazole group was 40.5±19.2 and in topical 5% Natamycin group was 40.8±16. Out of the 15 patients in Natamycin group, 6(40%) patients did not show any improvement, worsening seen in 4(27%), improvement was noted in 3(20%) and 2(13%) patients were cured of fungal corneal ulcer. Out of 15 patients in intrastromal Voriconazole group, 7(47%) patients showed improvement, 6(40%) patients were cured and worsening of ulcer was noted in 2(13%) patients. On comparison, outcome between two groups was found to be statistically significant (p&#60;0.006).5% Natamycin is a drug of choice for fungal corneal ulcer, however, due to poor penetration of topical antifungal drugs, in deep seated fungal corneal ulceration and abscesses it was not found to be very effective. In these cases, due to broader spectrum of activity, higher achieved concentration at infection site and lower complication rate, intrastromal Voriconazole could be considered as a primary therapy. Further prospective studies with larger sample size are needed toestablish the outcome.

Authors: Nehra Kajal , George  T Jisa , Bhardwaj Geeta , Pasricha Rajesh 
Published: December 2024

Objective: Breast cancer constituted 13.5% of all reported new cancer in India, with a notable mortality rate due to late presentation. The current research aims to address the extent of delay in presentation to the hospital and the factors that contribute to delayed presentation among breast cancer patients.
Materials and methods: A descriptive cross-sectional study was conducted among 138 primary breast cancer patients aged 18 to 60 years, with a time lag of more than 2 weeks between the initial recognition of symptoms and the first medical interaction. These patients were attending the oncology Outpatient Department (OPD) of tertiary care center in Central India, where female breast cancer patients receive treatment and follow-up care. The analysis employed binary logistic regression to assess the factors significantly affecting the delayed presentation to the hospital.
Results: Most of the participants were aged between 40 and 50 years and did not have a family history of breast cancer. The median delay in presentation to the hospital was 2 months. Women having breast lump as initial breast symptom tend to present late (> 3 months) to the hospital (p=0.037) and if the breast lump was smaller, they are more likely to delay seeking medical attention compared to those with larger breast lump (p=0.012).
Conclusion: The study indicates that many patients delayed seeking help due to small breast lumps. Improved screening services are needed for early detection. Future awareness campaigns should emphasize the link between breast lumps and cancer to reduce delays and improve patient quality of life.

Authors: Gayathri G.R. , Mini C. , Aparna B. 
Published: December 2024

Background: Anthocyanin is a natural non-toxic, water soluble and heat sensitive colouring pigment which is abundantly found in nature. Standardization of simple and viable technology for anthocyanin extraction from processing waste can replace the synthetic food colourants. Study on standardisation of dehydration method and solvent for anthocyanin extraction from pomegranate (Punica granatum L.) peel was carried out using maceration. Methods: Ripe pomegranate fruits (var. kabuli) of good quality and uniform maturity were cleaned, surface sanitized using 2 ppm ozonised water for 10 minutes and outer peel was separated from the arils and mesocarp. The peels were cut into uniform pieces of approximate 2cm3 and subjected to different dehydration treatments. Best dehydration treatment was selected based on highest anthocyanin content. The peel after dehydrating with the best method was macerated using three different solvents for selection of best solvent for extraction based on highest anthocyanin content. Result: Dehydration resulted in enhanced anthocyanin content. Cabinet drying of peel pieces at 50±5°C for 24 hrs followed by maceration using acidified ethanol with 1% HCl at 2:1 solvent to solid ratio can yield 25.5% colour extract with high anthocyanin content (84.57 mg 100 g-1) and antioxidant activity (82.83%).

Authors: Milton Cynthia , Vidhya Lokesh , Thiruvengadam Gayathri 
Published: December 2024

The level of reliance on AI-Powered Writing Tools (AI-PWT) profoundly impacts the independent writing skill of English as Second Language (ESL) learners. The present study explores the familiarity and utility of two different types of AI -Powered Writing Tools (Independent Writing with AI editing assistance; Generative writing with AI assistance) among ESL health science graduates and to understand the role of these tools in shaping their independent writing skills. Method: The study adopted a survey technique to understand the knowledge, attitude and utility of AI-powered writing tools among 309 Health Science graduates from a South Indian private Medical University. Result: The findings showed the overall frequency distribution of the participants’ level of knowledge had a higher score range of 14-20 in 213 (68.9%) samples. Although 215 (70%) were familiar on using AI-PWT to improve vocabulary and grammar, around 17-19 % were uncertain about receiving real-time writing feedback to optimize the content. 199 (64%) expressed a positive perspective in using AI-PWT. Around 214 (69.3 %) took assistance from AI-PWT for generative writing purposes than revising the independently written content. In practice, only 64 (20.7 %) received feedback to refine the vocabulary and 60 (19.4%) to revise grammar, indicating an inclination for more generative writing with AI utility than Independent Writing with editing assistance. Conclusion: AI-Powered Writing Tools are well-recognised and powerful writing assistance to help students with their academic writing. However, relying on these tools only for generative purposes could significantly affect independent writing. The study insists on the need for teacher-guided assistance to train students to adopt the right tool that could best serve as a collaborative writing assistant adhering to the ethics.
Position control systems with friction compensation for servo pneumatic actuators
Authors: Nikitin Artur , Levchenko Oleh 
Published: December 2024

This work is devoted to the development of control systems for a tracking pneumatic actuator, taking into account the current position of the working body of the actuator and the amount of friction in the friction pairs of the actuator. Implementing the positioning of a pneumatic actuator is a complex technical task, but at the same time extremely relevant, since industrial systems of modern production require the performance of technological operations not only with high speed but also with high accuracy of positioning the working body of the actuator. The paper also considers control systems for pneumatic actuators based on the position of the working body, taking into account the nonlinearity of motion caused by friction forces in the pneumatic actuator. Friction in the contact pairs of pneumatic actuators adversely affects the operation of the actuators, especially taking into account the dependence of friction on ambient temperature, the surface condition of the contact pairs, the availability and quality of lubricants, etc. The study demonstrates existing control systems and implemented static and dynamic models of friction compensation and the impact of such models on the accuracy and controllability of systems with different types of regulators and implementation schemes, including proportional distributors with analog control and high-speed direct-acting distributors. The paper analyzes positioning systems with the ability to regulate the inlet pressure and the impact of such system solutions on the system rigidity and its performance. The paper formulates a goal for further research and identifies a list of tasks necessary to achieve the goal set in the paper. The paper also presents a design solution for a test bench with the ability to implement adaptive control of the actuator force depending on changes in the operating parameters of the technological operation and changes in the parameters of the pneumatic system as a whole.
