RESUMO
Context: Psoriasis is a chronic, proliferative, and inflammatory skin disease related to the systemic manifestation of numerous organs. The typical lesion comprises red, scaly, sharply demarcated, indurated plaques, especially over the extensor surfaces and scalp. The degree and severity vary after some time and between people. Morphological variations are normal; both hereditary and environmental factors play important roles in etiology and pathogenesis.Psoriasis is very difficult to treat due to its chronicity. As a medical system, Homoeopathy treats both patients' physical ailments and overall wellness. The use of highly potentized homoeopathic anti-miasmatic intercurrent medicines will be very beneficial in dealing with this. Fifty-millesimal (LM) potency was a great discovery by Dr. Samuel Hahnemann. While treating numerous chronic illnesses, he was able to quickly relieve symptoms without any aggravation by using fifty-millesimal (LM) potency. Case Report: The present case report is of 24-year-old male patient having psoriasis for one year. This case report describes the homoeopathic management of psoriasis using fifty-millesimal (LM) potency. On the basis of presenting sign and symptoms, Arsenic Album 30C was prescribed with frequent repetitions after repertorisation. During follow-ups, Arsenic Album 1LM was prescribed in to accelerate the cure. Psoriasis is a chronic condition that tends to recur. To prevent the recurrence, Psorinum 1000C was prescribed as an intercurrent anti-miasmatic medicine in a single dose during the course of treatment. Psorinum is a nosode that was chosen for therapy since it is recommended when symptoms reappear and the best selected homoeopathic medicine is not very effective. Psorinum was prescribed in this case to clear the miasmatic obstruction because the Arsenic Album was only temporarily easing the complaints. Result: The patient has exhibited improvement in their mental state and quick alleviation from physical issues after receiving multiple doses of Arsenic Album 1LM and a single dose of Psorinum 1000C, all without their symptoms getting worse. The patient's condition was followed up on at every appointment for a considerable amount of time, and no new concerns had surfaced as of yet. Conclusion: This case report shows favourable results of homoeopathic medicine in fifty-millesimal (LM) potency. Therefore, it can be concluded that using fifty-millesimal (LM) potency of accurately selected homoeopathic medicine will shorten the cure process without the aggravation of symptoms. Further research studies are required to explore the efficacy of fifty-millesimal (LM) potency of homoeopathic medicine in treatment of chronic illnesses.
RESUMO
Gram-negative (GN) sepsis is a medical emergency where management in resource-limited settings relies on conventional microbiological culture techniques providing results in 3-4 days. Recognizing this delay in turnaround time (TAT), both EUCAST and CLSI have developed protocols for determining AST results directly from positively flagged automated blood culture bottles (+aBCs). EUCAST rapid AST (RAST) protocol was first introduced in 2018, where zone diameter breakpoints for four common etiological agents of GN sepsis, i.e., Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, and Acinetobacter baumannii complex can be reported. However, those clinical laboratories that have implemented this method in their routine workflow rely on mass spectrometry-based microbial identification, which is not easily available, thus precluding its implementation in resource-limited settings. To circumvent it, we evaluated a direct inoculum protocol (DIP) using a commercial automated microbial identification and antimicrobial susceptibility testing system (aMIAST) to enable early microbial identification within 8 h of positive flagging of aBC. We evaluated this protocol from January to October 2023 to identify the four RAST reportable GN (RR-GN) in the positively flagged aBC. The microbial identification results in DIP were compared with the standard inoculum preparation protocol (SIP) in aMIAST. Of 204 +aBCs with monomorphic GN (+naBC), one of the 4 RR-GN was identified in 105 +naBCs by SIP (E. coli: 50, K. pneumoniae: 20, P. aeruginosa: 9 and A. baumannii complex: 26). Of these, 94% (98/105) were correctly identified by DIP whereas major error and very major error rates were 6% (7/105) and 1.7% (4/240), respectively. When DIP for microbial identification is done using the EUCAST RAST method, provisional clinical reports can be provided within 24 h of receiving the sample. This approach has the potential to significantly reduce the TAT, enabling early institution of appropriate antimicrobial therapy.

BACKGROUND: A group of characteristics known as metabolic syndrome raises the chance of developing diabetes and cardiovascular disease. Insulin resistance (IR) and obesity are regarded as critical metabolic syndrome pathophysiology. OBJECTIVES: The diagnostic accuracy of IR indicators, triglyceride (TG) glucose index-neck circumference (TyG-NC), and TG glucose index-neck-to-height ratio (TyG-NHtR) to be evaluated for the detection of cardiovascular diseases and metabolic syndrome in nondiabetic individuals. MATERIALS AND METHODS: A cross-sectional study was conducted and passed by the Ethics Committee of the institute. The age should be 18 years or older, and subjects should not have diabetes. Each patient's clinical information was gathered, and lab tests were run. The study was done for a period of 1 year. RESULTS: The study has 100 participants. Around 74% of the group was women. Only 26.5% of the group had an obesity diagnosis. Poor fasting plasma glucose levels were found in 19.4% of the research team. Receiver operating characteristic (ROC)-area under the curve (AUC) testing revealed that all examined IR indices can differentiate individuals with metabolic syndrome from those who are healthy. Our analysis laid out the soaring high area under the ROC curve for TyG index and the low stunted area under the ROC curve for TyG-NC. For obesity, all indices showed appreciable diagnostic efficacy, indicating the maximum achieved area under the ROC curve for TyG index and the minimum recorded metabolic score for IR. The AUC in the case of the metabolic score for IR (METS-IR) male sample population was found to be not statistically compelling. CONCLUSION: The exploration of indirect indices, the proposed ones, namely TyG-NC and TyG-NHtR, emphasized an intricate link between cardiovascular diseases and metabolic syndrome.

Background Medication errors are common, especially by new trainees in primary care settings. Our study aimed at reducing the rate of prescription error in the pediatric outpatient department (OPD) of a secondary healthcare center in suburban north India using a quality improvement methodology. Methods Based on a survey and focused group discussion (FGD) involving all stakeholders, the identified problems and difficulties faced during outpatient prescriptions, interventions, and outcome parameters were drafted. The primary outcome measure was the prescription error rate evaluated by a senior resident (SR) of pediatrics, and the secondary outcome measures included the frequency of antibiotic prescriptions and investigations. Intervention Two cycles of Plan-Do-Study-Act (PDSA) were conducted on accessible drug formularies and standard treatment protocols for common pediatric conditions. Results The mean baseline prescription error was 72.2% (95% confidence interval (CI): 63.2-81.1). After the implementation of the first PDSA cycle, the mean error rate was 46.5% (95% CI: 36.6-56.5). There were eight consecutive points of prescription error below the control limit (63.2% and 81.1%) of the baseline. The PDSA-2 cycle showed the same shift to below the control limit (36.6% and 56.5%). The mean error rate found at the end of the PDSA-2 cycle was 22.5% (95% CI 15.7-29.5). There was no clinically significant difference in the number of investigations or antibiotics prescribed. Conclusion The application of standardized drug formularies and standard treatment protocols (STPs) can help reduce prescription errors, especially in a primary care setting. Expansion of such techniques to other centers could be particularly useful.
RESUMO
Juvenile fibromyalgia (JFMS) is a common disorder in the adolescent population with a prevalence of 1-6%. Our study looked at the prevalence of tinnitus in JFMS patients seen at a pediatric rheumatology clinic between 2016 and 2021. The objective of this study was to retrospectively assess prevalence of tinnitus and compare that with prevalence in non- JFMS patients presenting to the clinic. We also assessed prevalence of other sensory and pain symptoms, Widespread pain index >6 and abdominal pain in these two groups. Of the 290 forms evaluated, tinnitus was present in 31.1 % of JFMS subjects, versus only 3.5 % in non-JFMS subjects. There was a significant association between tinnitus and tingling and numbness among subjects with JFM (p = 0.005). On logistic regression analysis, the odds of having JFMS were 5.2 times higher among tinnitus patients compared to non-tinnitus (p = 0.003, 95 % CI 1.77-15.55). Tingling/numbness were also associated with 21.78 times increased odds for diagnosis of JFMS (p = 0.0003, 95 % CI 4.05-117.21). The odds of having JFMS were 22.6 times higher among patients with Widespread Pain Index >6 (p < 0.0001, 95 % CI 7.88-64.71). Tinnitus is a commonly prevalent condition in patients with JFMS. In patients with JFMS, there is a significant association between tinnitus and tingling/numbness. Further studies are needed to explore the underlying pathogenesis of these symptoms.

OBJECTIVES: We prospectively implemented a diagnostic stewardship care-bundle checklist, 'Sepsis-48 DSB', with the aim of reducing intervening duration of key steps of automated blood culture diagnostics (aBCD). METHODS: Sepsis-48 DSB was implemented for automated blood culture bottles (BCBs) received from adult intensive care units (AICUs) during the intervention period (P2; July 2020-June 2021) and intervening durations were compared with those during the retrospective, pre-intervention period (P1; March-June 2020). During both periods, provisional blood culture reports (pBCR) were issued wherein direct microbial identification (dID) was performed in BCBs with Gram-negatives by directly inoculating conventional biochemical tests and direct antimicrobial susceptibility testing (dAST) using EUCAST RAST method. The results were compared with the standard of care (SoC) method (i.e. full incubation followed by identification and AST by VITEKâ-2 Compact). RESULTS: During P2, significant reductions in loading time (LT; median: 63.5 vs. 32 minutes, P < 0.001), time to dID+dAST performance (TTD; 186 vs. 115 minutes, P = 0.0018) and an increase in compliance to bundle targets (LT ≤45: 44% vs. 66%, P = 0.006 and TTD ≤120: 34% vs. 51.7%, P = 0.03) were observed. Using dID+dAST method, results were read 694 minutes earlier than SoC method. Of 176 pBCR, 165 (94%) were concordant with SoC in microbial identification of species. Categorical agreement for any drug-bug combination was 92.7% (1079/1164) and corresponding major, very major, and minor error rates were 8.8% (19/216), 4.9% (45/921), and 1.8% (21/1164), respectively. CONCLUSION: The 'diagnostic stewardship care-bundle' strategy was successfully implemented with considerable diagnostic accuracy leading to significant reductions in duration of targeted steps of aBCD.
RESUMO
Background: Mineral buildups called kidney stones can be free-floating or affixed to the renal papillae and occur in the renal calyces and pelvis. A major morbidity is associated with the widespread problem of renal stone disease. Open surgical lithotomy and minimally invasive endourological procedures are now the standard for the management of kidney stone symptoms. However, individualized homeopathy (iHOM) has greatly improved treatment of Multiple Renal Calculi. Methods: In the OPD of Dr. D. Y. Patil Homoeopathic Medical College and Research Centre, a 26-year-old female patient with multiple renal calculus was treated homeopathically from August 2021 to January 2022. During the follow-up visits outcome was assessed. To assess whether the changes were due to homoeopathic medicine, an assessment using the modified Naranjo criteria was performed. Results: Over an observation period of 5 months beneficial result from iHOM medicine was seen and so can be used by the physicians in the treatment of Renal Calculi as a complementary health practice. Conclusion: Based on the totality of symptoms, individualized Homoeopathic Medicine (iHOM) Lycopodium Clavatum 30C was given and worked well to dissolve and expel all renal stones. Hence, homeopathy is effective in the fragmentation and ejection of renal calculi and remains one of the most popular treatments for urological problems.

The green approach has been employed for the synthesis of various types of nanomaterials including metal nanoparticles, metal oxides, and carbon-based nanomaterials. These processes involve natural sources that contain bioactive compounds that act as reducing, stabilizing, and capping agents for the formation and stabilization of nanomaterials. This study reports the green synthesis of CdS and CdS/rGO nanocomposites using Lactobacillus bacteria. The UV-visible spectrophotometer, field emission scanning electron microscopy, transmission electron microscopy, energy-dispersive X-ray spectroscopy, Raman spectroscopy, and Fourier transform infrared spectroscopy spectra confirm the synthesis of the nanocomposite. The electrochemical characterization using cyclic voltammetry, differential pulse voltammetry, and EIS revealed that the CdS/rGO nanocomposites showed a higher electron transfer rate compared with CdS nanoparticles, indicating the potential of the nanocomposites for biosensing applications. The zone of inhibition revealed significant antimicrobial activity against Escherichia coli and Staphylococcus aureus for both CdS nanoparticles and CdS/rGO nanocomposites. Additionally, CdS/rGO nanoparticles exhibited high photocatalytic activity for the degradation of methylene blue dye. Overall, this study demonstrates that the synthesized CdS and CdS/rGO nanocomposites have good electrochemical properties, photocatalytic, and antimicrobial activity and, therefore, can be employed for various applications such as biosensing, photocatalysis, and antimicrobial activity.

INTRODUCTION: Melioidosis is caused by the Gram-negative bacilli Burkholderia pseudomallei, which is found in contaminated water and soil and spreads via inhalation, inoculation, and ingestion. Melioidosis manifests diversely in immunocompetent and immunocompromised patients, ranging from asymptomatic to life-threatening respiratory distress, septic shock, localized tissue infection, necrotizing pneumonia, and soft organ abscesses. Methods: An 18-month observational study was conducted at a tertiary center in central India among various confirmed melioidosis cases, with data gathered and analyzed. Aerobic culture and sensitivity were performed in all studied cases, either in blood/body fluid/localized collection - using blood agar media for the culture and disc diffusion method on Mueller Hinton agar for sensitivity. Other tests, such as radiological imaging, were conducted according to symptoms and signs of localized infection. RESULTS: The melioidosis cases under study were compared on various clinical/presenting parameters. Melioidosis has a variety of risk factors, but we found that, in India, diabetic patients are at a higher risk of this infection, particularly fatal forms, as all of the patients in our study were diabetic. Melioidosis is known to have joint involvement, either as a source of infection or later in the course of the disease. All cases were successfully treated with antibiotics and surgical procedures, demonstrating the significance of determining disease etiology, early diagnosis, and rapid early management. CONCLUSION: Melioidosis is a potentially fatal disease, particularly in diabetics, with a wide range of symptoms and complications. Physicians face a variety of challenges, including clinical symptoms resembling other chronic illnesses, such as tuberculosis, delays in laboratory confirmation, underdiagnosis, reduced reporting, and a lack of suspicion. Because there are very little data and it is a seldom reported infection from central India, we are publishing a study on seven melioidosis patients.
RESUMO
OBJECTIVES: We prospectively implemented a diagnostic stewardship care-bundle checklist, 'Sepsis-48 DSB', with the aim of reducing intervening duration of key steps of automated blood culture diagnostics (aBCD). METHODS: Sepsis-48 DSB was implemented for automated blood culture bottles (BCBs) received from adult intensive care units (AICUs) during the intervention period (P2; July 2020-June 2021) and intervening durations were compared with those during the retrospective, pre-intervention period (P1; March-June 2020). During both periods, provisional blood culture reports (pBCR) were issued wherein direct microbial identification (dID) was performed in BCBs with Gram-negatives by directly inoculating conventional biochemical tests and direct antimicrobial susceptibility testing (dAST) using EUCAST RAST method. The results were compared with the standard of care (SoC) method (i.e. full incubation followed by identification and AST by VITEKâ-2 Compact). RESULTS: During P2, significant reductions in loading time (LT) [median: 63.5 vs. 32 minutes, P < 0.001], time to dID+dAST performance (TTD) [186 vs. 115 minutes, P = 0.0018] and an increase in compliance to bundle targets [LT ≤45: 44% vs. 66%, P = 0.006 and TTD ≤120: 34% vs. 51.7%, P = 0.03] were observed. Using dID+dAST method, results were read 694 minutes earlier than SoC method. Of 176 pBCR, 165 (94%) were concordant with SoC in microbial identification of species. Categorical agreement for any drug-bug combination was 92.7% (1079/1164) and corresponding major, very major, and minor error rates were 8.8% (19/216), 4.9% (45/921), and 1.8% (21/1164), respectively. CONCLUSION: The 'diagnostic stewardship care-bundle' strategy was successfully implemented with considerable diagnostic accuracy leading to significant reductions in duration of targeted steps of aBCD.

Objective Indian hospitals (especially government-run public sector hospitals) have a nonexistent antimicrobial stewardship program (AMSP). After successfully initiating AMSPs in tertiary care hospitals of India, the Indian Council of Medical Research envisages implementing AMSP in secondary care hospitals. This study is about the baseline data on antibiotic consumption in secondary care hospitals. Materials and Methods It was a prospective longitudinal observational chart review type of study. Baseline data on antibiotic consumption was captured by a 24-hour point prevalence study of antibiotic usage and bacterial culture rate. The prescribed antibiotics were classified according to the World Health Organization (WHO) Access, Watch, and Reserve classification. All data were collated in Microsoft Excel and summarized as percentages. Results Out of the 864 patients surveyed, overall antibiotic usage was 78.9% (71.5% in low-priority areas vs. 92.2% in high-priority areas). Most of the antibiotic usage was empirical with an extremely low bacterial culture rate (21.9%). Out of the prescribed drugs, 53.1% were from the WHO watch category and 5.5% from the reserve category. Conclusion Even after 5 years of the launch of the national action plan on AMR (NAP-AMR) of India, AMSP is still non-existent in small- and medium-level hospitals in urban cities. The importance of trained microbiologists in the health care system is identified as a fulcrum in combating antimicrobial resistance (AMR); however, their absence in government-run district hospitals is a matter of grave concern and needs to be addressed sooner than later.
RESUMO
Background Intestinal parasites are a major public health problem in tropical countries. Over 1.5 billion people are infected with soil-transmitted helminths (STH), of which 225 million are in India. Parasitic infections are associated with poor sanitation, lack of safe potable water, and improper hygiene. Materials and Methods The study was undertaken to ascertain the impact of control strategies, namely open-defecation free drive and mass drug administration of single dose albendazole. Stool samples received at AIIMS Bhopal Microbiology laboratory, across all age groups, were studied for protozoan trophozoites/cysts and helminthic ova. Results Out of 4,620 stool samples, 389 (8.41%) were positive either for protozoal or helminthic infections. Protozoan infections were more common than helminthic infections with Giardia duodenalis infection being the most common, 201 (51.67%), followed by Entamoeba histolytica , 174 (44.73%). The helminthic infections constituted 14 (3.5%) of the positive stool samples with Hookworm ova in 6 (1.5%) cases. Conclusion This study proves that strategies, namely "Swachh Bharat Abhiyan" and "National Deworming Day" started in 2014 and 2015 led to significant reduction of intestinal parasite infections in Central India, with a higher reduction of STH compared with protozoan parasite infection being ascribed to the activity spectrum of albendazole.
RESUMO
Introduction Bloodstream infection (BSI) and subsequent sepsis are life-threatening medical conditions. The onset of antimicrobial resistance and subsequent multi-drug resistant organisms (MDRO) significantly increase healthcare-associated expenditure with adverse clinical outcomes. The present study was undertaken to identify the trends of BSI in community settings in secondary care hospitals (smaller private hospitals and district hospitals) in the state of Madhya Pradesh in Central India with the support of the Indian Council of Medical Research (ICMR) and National Health Mission, Madhya Pradesh. Methodology The present study was a prospective, longitudinal observational chart review type of study. The study was carried out at 10 secondary care hospitals (eight smaller private hospitals and two government district hospitals) nominated by the State Government as part of the ICMR Antimicrobial Resistance Surveillance and Research Network (AMRSN). The hospitals were nominated depending on the availability of a microbiology laboratory and a full-time microbiologist. Result A total of 6202 blood samples were received from patients with suspected BSI, out of which 693 samples were positive for aerobic culture. Among these, 621 (89.6%) showed bacterial growth and 72 (10.3%) grew Candida species (spp). Out of the 621 bacterial growth samples, Gram-negative bacteria were 406 (65.3%) and Gram-positive bacteria were 215 (34.6%). Among the Gram-negative isolates (406), the predominant isolate was Escherichia coli (115; 28.3%) followed by Klebsiella pneumoniae (109; 26.8%), Pseudomonas aeruginosa (61; 15%), Salmonella spp. (52; 12.8%), Acinetobacter spp. (47; 11.6%) and the other Enterobacter spp. (22; 5.4%). Among the Gram-positive isolates (215), the predominant isolate was Staphylococcus aureus (178; 82.8%) followed by Enterococcus spp. (37; 17.2%). Among the Escherichia coli, third-generation cephalosporin resistance was identified in 77.6%, piperacillin-tazobactam resistance in 45.2%, carbapenem resistance in 23.5% and colistin resistance in 16.5% of cases. Among the Klebsiella pneumoniae, third-generation cephalosporin resistance was identified in 80.7%, piperacillin-tazobactam resistance in 72.8%, carbapenem resistance in 63.3% and colistin resistance in 14% of cases. Among the Pseudomonas aeruginosa, ceftazidime resistance was identified in 61.2%, piperacillin-tazobactam resistance in 55%, carbapenem resistance in 32.8%, and colistin resistance in 38.3% of cases. Among the Acinetobacter spp., piperacillin-tazobactam resistance was identified in 72.7%, carbapenem resistance in 72.3%, and colistin resistance in 9.3% cases. While analyzing the antibiogram for Staphylococcus aureus isolates, methicillin resistance (MRSA) was seen in 70.3% of cases, followed by vancomycin resistance (VRSA) in 8% of cases and linezolid resistance in 8.1%. Among the Enterococcus spp. isolates, linezolid resistance was found in 13.5%, vancomycin resistance (VRE) in 21.6%, and teicoplanin resistance in 29.7% of cases. Conclusion In conclusion, the first-ever study to identify the risk of high-end antibiotics causing significant drug resistance in secondary and tertiary care settings has highlighted the urgent need for more randomized control studies and proactive measures from healthcare authorities and serves as a beacon for future research efforts and underscores the importance of implementing antibiograms to combat the growing threat of antibiotic resistance.

RESUMO
This article describes a case of melioidosis, a severe and potentially fatal disease caused by the Gram-negative bacillus Burkholderia pseudomallei, in a 55-year-old female in India. The disease is endemic in Southeast Asia and Northern Australia. Recently there has been an increased number of cases reported in India. The source of B. pseudomallei in India is thought to be soil and water, with the most common mode of infection being through skin contact. The clinical presentation of melioidosis in India varies greatly, making diagnosis difficult. The case presented here with a history of acute febrile illness and progressive dyspnoea, with clinical worsening leading to intensive care unit (ICU) care. We managed this acute pneumonia-like melioidosis with antibiotics and supportive care which showed rapid recovery at follow-up. This case highlights the need for a high index of suspicion and increased awareness of early diagnosis of melioidosis in the Indian subcontinent to improve the patient.
RESUMO
G0/G1 switch gene 2 (G0S2) is known to inhibit lipolysis by inhibiting adipose triglyceride lipase (ATGL). In this report, we dissect the role of G0S2 in ER+ versus ER- breast cancer. Overexpression of G0S2 in ER- cells increased cell proliferation, while G0S2 overexpression in ER+ cells decreased cell proliferation. Transcriptome analysis revealed that G0S2 mediated distinct but overlapping transcriptional responses in ER- and ER+ cells. G0S2 reduced genes associated with an epithelial phenotype, especially in ER- cells, including CDH1, ELF3, STEAP4 and TACSTD2, suggesting promotion of the epithelial-mesenchymal transition (EMT). G0S2 also repressed estrogen signaling and estrogen receptor target gene signatures, especially in ER+ cells, including TFF1 and TFF3. In addition, G0S2 overexpression increased cell migration in ER- cells and increased estrogen deprivation sensitivity in ER+ cells. Interestingly, two genes downstream of ATGL in fat utilization and very important in steroid hormone biosynthesis, HMGCS1 and HMGCS2, were downregulated in G0S2 overexpressing ER+ cells. In addition, HSD17B11, a gene that converts estradiol to its less estrogenic derivative, estrone, was highly upregulated in G0S2 overexpressing ER+ cells, suggesting G0S2 overexpression has a negative effect on estradiol production and maintenance. High expression of G0S2 and HSD17B11 was associated with improved relapse-free survival in breast cancer patients while high expression of HMGSC1 was associated with poor survival. Finally, we deleted G0S2 in breast cancer-prone MMTV-PyMT mice. Our data indicates a complex role for G0S2 in breast cancer, dependent on ER status, that may be partially mediated by suppression of the estrogen signaling pathway.
RESUMO
OBJECTIVE: The growing availability of cannabis products through home delivery services may affect cannabis-related health outcomes. However, research is impeded by a lack of data measuring the scale of home delivery. Prior research demonstrated that crowdsourced websites can be used to validly enumerate brick-and-mortar cannabis outlets. We piloted an extension of this method to explore the feasibility of measuring availability of cannabis home delivery. METHOD: We tested implementation of an automated algorithm designed to webscrape data from Weedmaps, the largest crowdsourced website for cannabis retail, to count the number of legal cannabis retailers offering home delivery to the geographic centroid of each Census block group in California. We compared these estimates to the number of brick-and-mortar outlets within each block group. To assess data quality, we conducted follow-up telephone interviews with a subsample of cannabis delivery retailers. RESULTS: We successfully implemented the webscraping. Of the 23,212 block groups assessed, 22,542 (97%) were served by at least one cannabis delivery business. Only 461 block groups (2%) contained one or more brick-and-mortar outlets. In interviews, availability varied dynamically as a function of staffing levels, order sizes, time of day, competition, and demand. CONCLUSIONS: Webscraping crowdsourced websites could be a viable method for quantifying rapidly evolving availability of cannabis home delivery. However, key practical and conceptual challenges must be overcome to conduct a full-scale validation and develop methodological standards. Acknowledging data limitations, cannabis home delivery appears to be nearly universal in California, whereas availability of brick-and-mortar outlets is limited, underscoring the need for research on home delivery.

Objectives Surgical-site infections (SSIs) can complicate virtually any surgical procedure. While SSI can result from numerous causes, contamination of the surgical field can also contribute to it. Intraoperative bacterial contamination during clean orthopaedic procedures can be detected using perioperative cultures. We hypothesized that perioperative cultures could be used to predict possibility of development of SSI in patients undergoing clean orthopaedic surgeries. Materials and Methods We conducted a prospective cohort study at a tertiary care hospital over a 2-year period. Intraoperative surgical wound lavage fluid and closed suction drain tip obtained in the postoperative period were sent for aerobic culture. All patients were followed up to look for the development of SSI for a period of at least 30 days for those undergoing nonimplant surgery, and 90 days for those with implant surgery. Statistical Analysis Means with standard deviation of the continuous data were calculated. Fisher's exact test and chi-square test were used for the analysis of the categorical variables. Relative risk and odds ratio were calculated to evaluate the association of the parameters under study with SSI. Results A total of 384 patients satisfying the inclusion and exclusion criteria were included. Perioperative cultures detected surgical wound contamination in 39 patients (10.1%). Forty-five patients (11.7%) developed SSI during the follow-up period. Skin commensals constituted 59% of perioperative contaminants and accounted for 20% of the SSIs. The relative risk of developing SSI with perioperative contamination was 0.41 (95% confidence interval: 0.09-1.63). Conclusion Intraoperative surgical-site contaminants could be detected using perioperative cultures. However, these contaminants did not lead to SSI. Timely treatment of perioperative contamination with appropriate antibiotics and local wound care probably helped in the reduction of SSI.
RESUMO
PURPOSE: To determine the accuracy of direct microbial identification (dID) and antimicrobial susceptibility testing by EUCAST rapid antimicrobial susceptibility testing (rAST) methodology from positively flagged blood culture bottles (BCBs) as well as reduction in turnaround time (TAT) compared to standard methodology. METHODS: It was a hospital based, prospective cohort study conducted over a period of 21 months from March 2020 to November 2021 in which positively flagged blood culture bottles were simultaneously processed by dID â+ ârAST and by VITEK®-2 Compact system or Kirby-Bauer disk diffusion method. TAT was calculated as the time (hours) taken from receipt of sample in bacteriology laboratory to release of clinical reports with complete identification and susceptibility testing results in both methods. RESULTS: Of 301 dID â+ ârAST performed in study, 125 (41.5%) BCBs were identified as having one of the 8 reportable micro-organisms by EUCAST rAST standard. Amongst VITEK concordant BCBs with gram-negatives, mean reduction in TAT by dID â+ ârAST methodology was 23 â± â1.4 âh. Amongst VITEK concordant gram-negatives, Categorical Agreement (CA) rates for any drug-bug combination were 94.4%, 94.5% and 93.6% and Very Major Error (VME) rates were 3.1%, 3.4% and 3.9% at 4-, 6- and 8-h reading time, respectively. CONCLUSIONS: EUCAST rAST methodology can generate susceptibility testing reports a day earlier if incorporated into the laboratory workflow. For resource-limited settings, implementing EUCAST rAST approach can be used effectively in early reporting, which can reduce antimicrobial use and improve patient outcomes by promoting timely escalation or de-escalation of empirical antibiotic therapy.
