RESUMEN
This study investigates the synthesis and characterization of KSrVO4 phosphors doped with Er3+ ions using combustion synthesis route by using urea as a fuel. X-ray diffraction analysis confirmed the orthorhombic phase and nano-scale crystallite size of around 21 nm, while transmission electron microscopy showed spherical and rod-shaped morphologies. The studies detected upconversion emission spectra at 526, 542 and 643 nm, representing green and red transitions under 980 nm excitation. Downshifting emissions under 350 nm excitation revealed peaks at 492, 544 and 680 nm. The critical quenching concentration was 2.5 mol%, resulting from dipole-quadrupole interactions among dopant ions. The direct and indirect optical band gaps were calculated as 3.61 and 3.41 eV, respectively. The calculated chromaticity coordinates and color correlated temperature values of the phosphor surpassed 5000 K, suggesting its viability for cool LED applications. These findings emphasize KSrVO4:Er3+ as a promising greenish component in white LEDs and a potent upconverting luminescence material for bio-imaging and photovoltaics.
RESUMEN
BACKGROUND: In recent years, the integration ofArtificial intelligence (AI) into various fields of medicine including Gynaecology, has shown promising potential. Surgical treatment of fibroid is myomectomy if uterine preservation and fertility are the primary aims. AI usage begins with the involvement of LLM (Large Language Model) from the point when a patient visits a gynecologist, from identifying signs and symptoms to reaching a diagnosis, providing treatment plans, and patient counseling. OBJECTIVE: Use of AI (ChatGPT versus Google Bard) in the surgical management of fibroid. STUDY DESIGN: Identifyingthe patient's problems using LLMs like ChatGPT and Google Bard and giving a treatment optionin 8 clinical scenarios of fibroid. Data entry was done using M.S. Excel and was statistically analyzed using Statistical Package for Social Sciences (SPSS Version 26) for M.S. Windows 2010. All results were presented in tabular form. Data were analyzed using nonparametric tests Chi-square tests or Fisher exact test.pvalues < 0.05 were considered statistically significant. The sensitivity of both techniques was calculated. We have used Cohen's Kappa to know the degree of agreement. RESULTS: We found that on the first attempt, ChatGPT gave general answers in 62.5 % of cases and specific answers in 37.5 % of cases. ChatGPT showed improved sensitivity on successive prompts 37.5 % to 62.5 % on the third prompt. Google Bard could not identify the clinical question in 50 % of cases and gave incorrect answers in 12.5 % of cases (p = 0.04). Google Bard showed the same sensitivity of 25 % on all prompts. CONCLUSION: AI helps to reduce the time to diagnose and plan a treatment strategy for fibroid and acts as a powerful tool in the hands of a gynecologist. However, the usage of AI by patients for self-treatment is to be avoided and should be used only for education and counseling about fibroids.

A Comparison of Ovarian Loss Following Laparoscopic versus Robotic Cystectomy As Analyzed by Artificial Intelligence-Powered Pathology Software. Background and Objective: To compare the area of ovarian tissue and follicular loss in the excised cystectomy specimen of endometrioma performed by laparoscopic or robotic technique. Methods: Prospective observational study performed between April 2023 to August 2023. There were 14 patients each in Laparoscopic group (LC) and Robotic group (RC). Excised cyst wall sent was for to the pathologist who was blinded to the technique used for cystectomy. The pathological assessment was done by artificial intelligence-Whole Slide Imaging (WSI) software. Results: The age was significantly lower in LC group; the rest of demographic results were comparable. The mean of the median ovarian area loss [Mean Rank, LC group (9.1 ± 15.1); RC (8.1 ± 12.4)] was higher in LC group. The mean of the median total follicular loss was higher in LC group (8.9 ± 9.2) when compared to RC group (6.3 ± 8.9) and was not significant. The area of ovarian loss in bilateral endometrioma was significantly higher in LC group (mean rank 7.5) as compared to RC group (mean rank 3) - (P = .016) despite more cases of bilateral disease in RC group. With increasing cyst size the LC group showed increased median loss of follicles when compared to RC group (strong correlation coefficient 0.347) but not statistically significant (P = .225). AAGL (American Association of Gynecologic Laparoscopists) score did not have any impact on the two techniques. Conclusion: Robotic assistance reduces the area of ovarian and follicular loss during cystectomy of endometrioma especially in bilateral disease and increasing cyst size. It should be considered over the laparoscopic approach if available.

INTRODUCTION: Gastrointestinal neuropathies are frequently found in diabetic patients. AIM: The aim of this study was to find out the safety, adverse reactions, and long-term effectiveness of Pistacia lentiscus plant extract (mastic gum) in diabetic gastroparesis (DG) with respect to sustainable improvement in gastroparesis symptoms (Gastrointestinal Cardinal Symptom Index [GCSI] score) by observational follow-up study of a single-centric double-blind noninferiority randomized control trial. MATERIALS AND METHODS: Thirty-eight individuals were recruited and equally randomized in two study groups based on GCSI score and TC99 radionuclide gastric emptying scintigraphy (GES), i.e. the mastic gum group and the levosulpiride group. After 24 weeks, the GCSI score was recalculated in both the groups, and patients were evaluated for the safety, adverse reactions, and long-term effectiveness of mastic gum and the standard drug levosulpiride. RESULTS: In the extended study, mean GCSI score changes at 24 weeks were statistically significant (P < 0.001) (t-test) between the two groups. In the mastic gum arm, the change in mean GCSI score at 24 weeks was statistically nonsignificant mean ± (standard deviation [SD]) 16.7± (3.81) compared to the GCSI score at 2-month postintervention mean (SD) 16.35± (2.27) (intragroup P = 0.89) (repeated measures ANOVA). It strongly indicates that mastic gum provided a sustainable improvement in DG symptoms in comparison to levosulpiride, with excellent subjective well-being postintervention, without any obvious significant adverse effects. CONCLUSION: Six-month (24-week) interim analysis of patients suggests that mastic gum gives a sustainable improvement in DG symptoms without any obvious adverse effects as compared to levosulpiride.

Introduction: Gastrointestinal neuropathies are frequently found in diabetic patients. The pathogenesis of diabetic gastroparesis (DG) is multifactorial. The usual treatment for DG includes dietary modifications, prokinetic and antiemetic agents. There is increasing demand for more effective medicines to treat DG. The current study was conducted on the Pistacia lentiscus stem extract to add to the armamentarium of DG treatment and to find the efficacy of P. lentiscus plant extract (mastic gum) in comparison to levosulpiride in DG for improvement in gastroparesis symptoms and gastric emptying scintigraphy (GES) in a single centric double-blind non-inferiority randomised control trial. Methods: Thirty-eight individuals were recruited and equally randomised into two study groups based on Gastroparesis Cardinal Symptom Index (GCSI) score and TC99 Radionuclide GES, mastic gum group and levosulpiride group. Both pre and post-intervention (8 weeks) GCSI scores were calculated, GES was performed to quantify the improvement in gastric emptying. Power analysis was performed using G*POWER software version 3.1.9.7 and data analysis using SPSS 23.0, variables measured in mean ± standard deviation (SD). Various statistical tests were used such as independent t-test, Chi-square test or Fisher's exact test, Wilcox Mann-Whitney test, analysis of variance (ANOVA) test, and posthoc pairwise tests. Results: The mastic gum is found effective in the improvement of 4 h gastric emptying percentage from the mean (SD) 76.60 (± 9.96) to mean (SD) 97.20 (2.17)% (P < 0.001). Mastic gum has the property of HbA1c reduction, which is more significant than that of levosulpiride (P = 0.044). Mastic gum also had significant Low density lipoprotein (LDL) (mg/dL) levels reduction, (P < 0.001), compared to levosupiride. An absolute increase was observed in haemoglobin (HB) level in mastic gum at a 2-month mean (SD) of 1.03 (0.77) (g/dL) (P-value <0.001). Conclusions: To our knowledge, this is the first study to compare the effect of levosulpiride with mastic gum concerning improvement in diabetic gastroparesis (DG) using GES. In the study, mastic gum was found to have great properties to improve DG with many important pleiotropic effects.
RESUMEN
Background: Psychotropic medications are prescription drugs that are commonly used to control some symptoms associated with many different types of mental ill health. Although they cannot cure a patient illness, they can assist with the management of some extremely distressing symptoms and this in turn can facilitate individuals in leading a more fulfilled life. Aims and Objective: This study attempts to collect the demographic details of the outpatient in the psychiatric department and to describe the usage, prescribing trends and cost-effectiveness of antipsychotics in psychiatry OPD among various clinical conditions to older and younger patients with psychiatry disorders. Material and Methods: This study was a prospective observational study, conducted over a period of 6 months from November 2021 to April 2022 in the Department of Psychiatry, Chidambaram Government Medical College and Hospital, a 1400 bedded multi-specialty tertiary care teaching hospital, Tamil Nadu Dr. M.G.R. Medical University Chennai, Tamil Nadu. The recruitment of subjects was carried out with the help the physicians who had the knowledge of patient's history and caregivers consenting to the study protocol and patients with case sheets carrying antipsychotics prescription. Observation and Results: A total number of 150 cases were enrolled in this study. All psychiatric OPD cases were studied and the results were taken. Based on the inclusion and exclusion criteria, 93 were the anti-psychotics prescribed cases and 57 were the non-anti-psychotics prescribed cases. Out of 93 patients, 69.89% (65 patients) were male and 30.10% (28 patients) were female. Out of non-psychotic 57 patients, 27 were male patients and 30 were female patients. Out of the 93 OPD patients, 40% of the patients have psychological based symptoms followed by 17% of patients have behavioral symptoms. 86.02% of patients received atypical antipsychotic medications in comparison with 36.55% of patients received the typical antipsychotic medications. Conclusion: In this study, we had observed the usage and types of anti-psychotic drugs to control and minimize the different psychotic symptoms among the OPD patients. Maximum antipsychotics studied were cost-effective and cheaper in Pradhan Mantri Bhartiya Janaushadhi Pariyojana (PMBJP) as compared to Intas, Torrent, Sun, Linux, Cipla, Abbott, Alkem, and Sanofi.
RESUMEN
Diabetes mellitus (DM) is a clinical syndrome that is manifested by hyperglycemia. Out of the numerous causes of diabetes, an uncommon cause is chronic pancreatic disease due to destruction of islet cells. Diabetic ketoacidosis is a rare entity in such cases as alpha cells are destroyed along with beta cells, which causes lack of glucagon that is responsible for ketogenesis. We hereby report a case of a 55-year-old woman with history of gall stone disease and who presented to the emergency department with multiple episodes of non-bilious, non-blood mixed vomiting along with increased frequency of micturition on background of malaise and anorexia along with significant weight loss. Her capillary blood glucose was 501 mg/dl, arterial blood gas showed high anion gap metabolic acidosis, and urine ketone were largely positive. Thus, she was diagnosed with diabetic ketoacidosis. She was admitted to the high dependency unit and her condition was treated along the lines of diabetic ketoacidosis. Further evaluation showed high HbA1c values without previous history of diabetes and computed tomography of the abdomen revealed presence of chronic pancreatitis. Though being a rare entity, this case outlines that DM3c can present with diabetic ketoacidosis (DKA); thus, early diagnosis and management are crucial to prevent mortality.
RESUMEN
Background: Diabetes mellitus (DM) is a chronic hyperglycaemic state associated with microvascular structural alterations. Nailfold capillaroscopy (NFC) is an in vivo study of microvascular circulation. Aims and Objectives: This study aimed to investigate the diameters of capillary loops and morpho-structural changes using a handheld dermatoscope in patients with type 2 DM (T2DM) with and without diabetic retinopathy (DR) and to establish nailfold capillary changes and NFC score as a non-invasive method to identify microvascular complication in T2DM patients. Material and Methods: A cross-sectional observational study was conducted in AIIMS Rishikesh for 6 months from August 2022 to February 2023. Our study participants were 100 adults more than 18 years of age diagnosed with T2DM, based on the American Diabetes Association (ADA) criteria. All patients were evaluated thoroughly for the presence of microvascular complications in the form of retinopathy. Based on this, they were divided into two groups-group 1 (T2DM with retinopathy) and group 2 (T2DM without retinopathy). Both groups were further subdivided into three subgroups based on haemoglobin A1c (HbA1c): the first group with HbA1c <7%, the second group with HbA1c 7-8.9% and the third group with HbA1c >=9%. For all the study participants, a detailed NFC was done for all 8 fingernails (excluding the thumb), using a handheld dermatoscope. Abnormal capillary shapes (ACS) were recorded by semi-quantitative score (NFC score). Results: A significant association was seen in capillary density (loops/mm) (5.83 ± 0.72 in the DR group and 6.3 ± 0.89 in the no-DR group) (P value = 0.005), capillary density (loops/3 mm) (P value = 0.005), total number of microhaemorrhages/3 mm (P value < .0001), total number of giant capillaries/3 mm (P value = 0.0004), total number of avascular areas/3 mm (P value = 0.0005), enlarged capillaries/3 mm (P value = 0.002), tortuous capillaries/3 mm (P value < .0001), abrogated/bushy capillaries/3 mm (P value = 0.004), number of fingers involved excluding the thumb (P value < .0001) and total nailfold capillaroscopic score (P value < .0001) between the two groups, one with DR and another without DR. Furthermore, the proportion of patients with abnormal nailfold capillaroscopic findings, abnormal NFC score, was significantly higher in patients with DR as compared to patients without DR (51.85% vs 4.35%, respectively) (P value < 0.0001). Conclusion: Our results suggest that NFC could possibly be used as an adjunctive tool in diabetics for diagnosing or monitoring microvascular complications with total NFC score being the significant predictor of DR at a cut-off point of >0 with the area under the curve (AUC) of 0.745 for correctly predicting DR.
RESUMEN
Kimura disease is an uncommon disease entity that typically involves the lymph nodes predominantly in the head and neck region together with frequent involvement of salivary glands. Very few cases of it have been reported in literature globally, and in the context of India, it is even rare. Early suspicion of Kimura disease may prevent the patient from unnecessary invasive diagnostic tests. We present a case scenario of a 35 years old female, from a hilly area who presented with painless neck swelling for 3 months that was followed by fever, new onset pain at the site of neck swelling, and skin rashes. Diagnosis of Kimura disease was made based on histopathological findings aided by peripheral eosinophilia and elevated serum Immunoglobulin E (IgE) levels. Following the diagnosis, the patient was treated with a short course of oral steroids which produced an excellent response with a consequent decrease in the size of lymph nodes and resolution of the skin rashes.
RESUMEN
BACKGROUND: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus has become a pandemic for the last 2 years. Inflammatory response to the virus leads to organ dysfunction and death. Predicting the severity of inflammatory response helps in managing critical patients using serology tests IgG and IgM. AIM: To investigate the correlation of the serology (IgM and IgG) with reverse transcriptase polymerase chain reaction (RT-PCR) status, disease severity [mild to critical], intensive care unit (ICU) admission, septic shock, acute kidney injury, and in-hospital mortality. METHODS: We conducted a longitudinal study to correlate serum SARS-CoV-2 immunoglobulin M (IgM) and immunoglobulin G (IgG) serology with clinical outcomes in coronavirus disease 2019 (COVID-19) patients. We analyzed patient data from March to December 2020 for those who were admitted at All India Institute of Medical Sciences Rishikesh. Clinical and laboratory data of these patients were collected from the e-hospital portal and analyzed. A correlation was seen with clinical outcomes and was assessed using MS Excel 2010 and SPSS software. RESULTS: Out of 494 patients, the mean age of patients was 48.95 ± 16.40 years and there were more male patients in the study (66.0%). The patients were classified as mild-moderate 328 (67.1%), severe 131 (26.8%), and critical 30 (6.1%). The mean duration from symptom onset to serology testing was 19.87 ± 30.53 d. In-hospital mortality was observed in 25.1% of patients. The seropositivity rate (i.e., either IgG or IgM > 10 AU) was 50%. IgM levels (AU/mL) (W = 33428.000, P ≤ 0.001) and IgG levels (AU/mL) (W = 39256.500, P ≤ 0.001), with the median IgM/ IgG levels (AU/mL), were highest in the RT-PCR-Positive group compared to RT-PCR-Negative clinical COVID-19. There was no significant difference between the two groups in terms of all other clinical outcomes (disease severity, septic shock, ICU admission, mechanical ventilation, and mortality). CONCLUSION: The study showed that serology levels are high in RT-PCR positive group compared to clinical COVID-19. However, serology cannot be useful for the prediction of disease outcomes. The study also highlights the importance of doing serology at a particular time as antibody titers vary with the duration of the disease. In week intervals there was a significant correlation between clinical outcomes and serology on week 3.
RESUMEN
COVID-19 has caused devastating effects worldwide ever since its origin in December 2019. IL-6 is one of the chief markers used in the management of COVID-19. We conducted a longitudinal study to investigate the role of IL-6 in diagnosis, treatment, and prognosis of COVID-19-related cytokine storm. Patients with COVID-19 who were admitted at AIIMS Rishikesh from March to December 2020 were included in the study. Patients with no baseline IL-6 value at admission and for whom clinical data were not available were excluded. Clinical and laboratory data of these patients were collected from the e-hospital portal and entered in an excel sheet. Correlation was seen with other inflammatory markers and outcomes were assessed using MS Excel 2010 and SPSS software. A total of 131 patients were included in the study. Of these, 74.8% were males, with mean age 55.03 ± 13.57 years, and mean duration from symptom onset being 6.69 ± 6.3 days. A total of 82.4% had WHO severe category COVID-19, with 46.56% having severe hypoxia at presentation and 61.8% of them having some comorbidity. Spearman rank correlation coefficient of IL-6 with D-dimer was 0.203, with LDH was -0.005, with ferritin was 0.3, and with uric acid was 0.123. A total of 11 patients received Tocilizumab at a mean duration from symptom onset of 18.09 days, and 100% mortality was observed. Deaths were reported more in the group with IL-6 ≥ 40 pg/mL (57.1% vs. 40.2%, p = 0.06). ICU admissions and ventilator requirement were higher in the IL-6 ≥ 40 pg/mL group (95.9% vs. 91.4%, p = 0.32 and 55.1% vs. 37.8%, p = 0.05). The study showed that IL-6 can be used as a possible "thrombotic cytokine marker". Higher values of IL-6 (≥40 pg/mL) are associated with more deaths, ICU admissions, and ventilator requirement.
RESUMEN
Antiphospholipid syndrome (APS) is an autoimmune disease present most commonly in young women, characterized by the presence of antibodies against various phospholipids and culminating in alteration of the flow of blood, leading to arterial and venous thrombosis. Although it can present with a wide range of manifestations, digital gangrene is one of the important ones. We present a case of a young female with antiphospholipid syndrome who presented with acute onset bilateral upper limb symmetrical digital gangrene with prior history of multiple fetal losses. Acute onset, symmetrical gangrene, limited to the bilateral upper limbs without venous system involvement, that too in association with systemic lupus erythematosus (SLE) which does not usually manifest as such make this case a unique and interesting one.
RESUMEN
Pseudomonas aeruginosa is the leading nosocomial and community-acquired pathogen causing a plethora of acute and chronic infections. The Centers for Disease Control and Prevention has designated multidrug-resistant isolates of P. aeruginosa as a serious threat. A novel delivery vehicle capable of specifically targeting â¯P. aeruginosa, and encapsulating antimicrobials, may address the challenges associated with these infections. We have developed hetero-multivalent targeted liposomes functionalized with host cell glycans to increase the delivery of antibiotics to the site of infection. Previously, we have demonstrated that compared with monovalent liposomes, these hetero-multivalent liposomes bind with higher affinity to P. aeruginosa. Here, compared with nontargeted liposomes, we have shown that greater numbers of targeted liposomes are found in the circulation, as well as at the site of P. aeruginosa (PAO1) infection in the thighs of CD-1 mice. No significant difference was found in the uptake of targeted, nontargeted, and PEGylated liposomes by J774.A1 macrophages. Ciprofloxacin-loaded liposomes were formulated and characterized for size, encapsulation, loading, and drug release. In vitro antimicrobial efficacy was assessed using CLSI broth microdilution assays and time-kill kinetics. Lastly, PAO1-inoculated mice treated with ciprofloxacin-loaded, hetero-multivalent targeted liposomes survived longer than mice treated with ciprofloxacin-loaded, monovalent targeted, or nontargeted liposomes and free ciprofloxacin. Thus, liposomes functionalized with host cell glycans target P. aeruginosa resulting in increased retention of the liposomes in the circulation, accumulation at the site of infection, and increased survival time in a mouse surgical site infection model. Consequently, this formulation strategy may improve outcomes in patients infected with P. aeruginosa.

INTRODUCTION: One of the competencies expected of all doctors posted in coronavirus disease 2019 (COVID-19) wards, is ECG rhythm identification, interpretation, and intervention for immediate management of patients. This study was undertaken to evaluate the effectiveness of the ECG training module as a component of preparedness training to combat COVID-19. METHODOLOGY: This was a cross-sectional study conducted during training on ECG rhythm identification, interpretation, its management in COVID-19 patients. Study participants included faculty, senior residents, junior residents, and interns of medical, surgical, and paraclinical disciplines. The training session included one hour of didactic lecture and one and half hours of interactive session during which case scenarios were discussed. An objective assessment was conducted through pre-test and post-test. Mean of pre and post-test scores were compared using paired t-test for evaluating statistical significance. Feedback was also taken from participants. RESULTS: Out of the 800 participants who gave consent, only 682 who completed both pre and post-test were included in the final analysis. Mean pre-test and post-test scores were 9.29/15 (61.9%) and 11.63/15 (77.5%), respectively, with a mean improvement of +2.34/15 (+15.6%). Of the participants, 38.6% obtained low scores in pre-test and 82% of respondents agreed that knowledge and skills gained from training would be useful in providing patient care. CONCLUSION: Low baseline knowledge on ECG highlights the need for re-training doctors posted in COVID-19 care on cardiac rhythm identification and interpretation. Interactive training is effective in improving ECG interpretative skills among doctors across disciplines and is the appropriate method to retrain/reskill, especially for large-scale capacity building.
