ABSTRACT
Objectives To analyze the spatial and temporal aggregation of multidrug resistant pulmonary tuberculosis (MDR-TB) incidence in Nanning at the township / street scale from 2017 to 2021, to explore the spatial and temporal characteristics of the spread of MDR-TB in Nanning, and to provide a scientific reference basis for the health administrative departments to achieve the precise implementation of MDR-TB prevention and control. Methods Based on the data of MDR-TB cases in Nanning from 2017 to 2021, the spatial-temporal scanning analysis software SaTScan v9.7 was used to retrospectively detect and analyze the areas where MDR-TB cases gathered. Results Through simple spatial scanning analysis, it was found that there were three first-class aggregation areas (the aggregation center was Fujiayuan Street, Jiangnan District, 2017, Xinyang Street, Xixiangtang District, 2019, and Zhonghe Town, Yongning District, 2020), and one second-class aggregation area (the aggregation center was Jinchai Town, Mashan County, 2020). Simple time scanning showed that the clustering occurred from May 2019 to December 2020. Temporal and spatial aggregation analysis showed that Xinyang Street in Xixiangtang District was the center of the first-class aggregation area, Zhonghe Town in Yongning District was the center of the second-class aggregation area, and Jinchai Town in Mashan County was the center of the third-class aggregation area. Conclusion The multidrug resistant pulmonary tuberculosis epidemic in Nanning is distributed in an aggregated manner, especially in Xinyang Street, Xixiangtang District, which has the highest spatial and temporal aggregation. It is necessary to focus on and take regional prevention and control measures to control the epidemic.
ABSTRACT
Aim To establish NCI-H446/EP for small cell lung cancer resistant cells resistant to cisplatin and etoposide, and to evaluate their biological characteristics and multidrug resistance. Methods Nude mice were subcutaneously inoculated with NCI-H446 cells of SCLC to construct an in vivo model of xenograft tumor, and were given first-line EP regimen treatment for SCLC, inducing drug resistance in vivo, and stripping tumor tissue in vitro culture to obtain drug-resistant cells. The resistance coefficient, cell doubling time, cell cycle distribution, expression of multidrug resistance gene (MDR1), and drug resistance-related protein were detected in vitro, and the drug resistance to cisplatin and etoposide in vivo were verified. Results Mice with NCI-H446 tumors acquired resistance after eight weeks' EP regimen treatment, and the drug-resistant cell line NCI-H446/EP was obtained by isolation and culture in vitro. The resistance factors of this cell line to cisplatin, etoposide, SN38 and doxorubicin were 12.01, 18.36, 65.4 and 10.12, respectively. Compared with parental cells, the proportion of NCIH446/EP cells in Q
ABSTRACT
The disease spectrum of ABCB4 gene mutation involves various diseases such as progressive familial intrahepatic cholestasis type 3 （PFIC3）， gallstone disease， intrahepatic cholestasis of pregnancy， portal hypertension， liver cirrhosis， and even primary hepatic and biliary malignancies. A young male patient was admitted to Department of Hepatobiliary Medicine， Eastern Hepatobiliary Surgery Hospital， and was initially diagnosed with liver cirrhosis and gallstones， and he was planned to receive laparoscopic cholecystectomy. Preoperative examination showed abnormal liver function， liver cirrhosis， splenomegaly， and mild esophageal varices， and next-generation sequencing was performed to make a confirmed diagnosis of ABCB4 gene mutation-associated liver cirrhosis with gallstones. The liver function of the patient gradually returned to normal after cholagogic treatment with ursodeoxycholic acid capsules.
ABSTRACT
Modulating Tankyrases (TNKS), interactions with USP25 to promote TNKS degradation, rather than inhibiting their enzymatic activities, is emerging as an alternative/specific approach to inhibit the Wnt/β-catenin pathway. Here, we identified UAT-B, a novel neoantimycin analog isolated from Streptomyces conglobatus, as a small-molecule inhibitor of TNKS-USP25 protein-protein interaction (PPI) to overcome multi-drug resistance in colorectal cancer (CRC). The disruption of TNKS-USP25 complex formation by UAT-B led to a significant decrease in TNKS levels, triggering cell apoptosis through modulation of the Wnt/β-catenin pathway. Importantly, UAT-B successfully inhibited the CRC cells growth that harbored high TNKS levels, as demonstrated in various in vitro and in vivo studies utilizing cell line-based and patient-derived xenografts, as well as APCmin/+ spontaneous CRC models. Collectively, these findings suggest that targeting the TNKS-USP25 PPI using a small-molecule inhibitor represents a compelling therapeutic strategy for CRC treatment, and UAT-B emerges as a promising candidate for further preclinical and clinical investigations.
ABSTRACT
ABSTRACT Objective: To determine the role of the IL8 rs4073 polymorphism in predicting the risk of central nervous system (CNS) toxicity in patients receiving standard pharmacological treatment for multidrug-resistant tuberculosis (MDR-TB). Methods: A cohort of 85 consenting MDR-TB patients receiving treatment with second-line antituberculosis drugs had their blood samples amplified for the IL8 (rs4073) gene and genotyped. All patients were clinically screened for evidence of treatment toxicity and categorized accordingly. Crude and adjusted associations were assessed. Results: The chief complaints fell into the following categories: CNS toxicity; gastrointestinal toxicity; skin toxicity; and eye and ear toxicities. Symptoms of gastrointestinal toxicity were reported by 59% of the patients, and symptoms of CNS toxicity were reported by 42.7%. With regard to the genotypes of IL8 (rs4073), the following were identified: AA, in 64 of the study participants; AT, in 7; and TT, in 11. A significant association was found between the dominant model of inheritance and CNS toxicity for the crude model (p = 0.024; OR = 3.57; 95% CI, 1.18-10.76) and the adjusted model (p = 0.031; OR = 3.92; 95% CI, 1.13-13.58). The AT+TT genotype of IL8 (rs4073) showed a 3.92 times increased risk of CNS toxicity when compared with the AA genotype. Conclusions: The AT+TT genotype has a tendency to be associated with an increased risk of adverse clinical features during MDR-TB treatment.
RESUMO Objetivo: Determinar o papel do polimorfismo rs4073 do gene IL8 na previsão do risco de toxicidade do sistema nervoso central (SNC) em pacientes em tratamento farmacológico padrão para tuberculose multirresistente (TBMR). Métodos: Amostras de sangue de uma coorte de 85 pacientes com TBMR que assinaram um termo de consentimento livre e esclarecido e que estavam recebendo tratamento com medicamentos antituberculosos de segunda linha foram amplificadas para o gene IL8 (rs4073) e genotipadas. Todos os pacientes foram avaliados clinicamente quanto a evidências de toxicidade do tratamento e categorizados de acordo com os achados. Foram avaliadas as associações brutas e ajustadas. Resultados: As principais queixas enquadraram-se nas seguintes categorias: toxicidade do SNC; toxicidade gastrointestinal; toxicidade cutânea; e toxicidade ocular e ototoxicidade. Sintomas de toxicidade gastrointestinal foram relatados por 59% dos pacientes, e sintomas de toxicidade do SNC foram relatados por 42,7%. Foram identificados os seguintes genótipos de IL8 (rs4073): AA, em 64 dos participantes; AT, em 7; TT, em 11. Houve associação significativa entre o modelo dominante de herança e toxicidade do SNC no modelo bruto (p = 0,024; OR = 3,57; IC95%: 1,18-10,76) e no ajustado (p = 0,031; OR = 3,92; IC95%: 1,13-13,58). O genótipo AT+TT do gene IL8 (rs4073) apresentou risco 3,92 vezes maior de toxicidade do SNC que o genótipo AA. Conclusões: O genótipo AT+TT tende a se associar a um maior risco de características clínicas adversas durante o tratamento da TBMR.
ABSTRACT
Vivenciamos a trajetória de uma usuária-guia no tratamento para tuberculose multidroga resistente (TB-MDR). As narrativas das redes vivas na produção de cuidado apontam para os seguintes itens: 1) cuidar no ato de viver: suplantar os estigmas e cultivar vínculos que ajudem a superar os discursos fomentados pelo medo, preconceitos, exclusão e invisibilidade dos sujeitos; 2) redes vivas de cuidado: os entremeios da norma; e 3) as interfaces de atenção usuário-trabalhador da saúde: como desmistificar o julgamento dos trabalhadores da saúde, que, subordinados a protocolos limitantes, muitas vezes estigmatizam o usuário como "abandonador de tratamento"?. A usuária-guia vislumbrou que cuidar é se desterritorializar, é colocar os desejos como potência para transformação, saindo do modus operandi rumo à criatividade, tendo o usuário no centro do processo.

We followed the trajectory of a guiding user undergoing treatment for multidrug-resistant tuberculosis (MDR-TB). The narratives of Live Networks in care production showed: 1) Caring in the act of living: Overcoming stigmas and cultivating bonds that help overcome discourses fostered by fear, prejudice, exclusion and invisibility of subjects; 2) Live Networks of care: The in-betweens of the norm; and 3) Interfaces of user-health worker care: How can we demystify the judgment of health workers who, subordinated to limiting protocols, often stigmatize the user as someone who "abandons the treatment"? The guiding user perceived that caring means deterritorializing oneself, expressing one's desires as power for transformation, and leaving the modus operandi towards creativity, with the user at the center of the process.

Background: Bacteriophages offer one of the most promising solutions to the challenges of antimicrobial resistance in bacteria. The aim of this study is to investigate bacteriophages as a source of new antimicrobial therapy. Methodology: Waste water samples were randomly collected from 8 different locations in the city of Lomé for bacteriophage isolation. The phages were isolated using multi-resistant clinical isolates (Escherichia coli 1642 and Staphylococcus aureus 0868) as hosts by means of a spot test. The host range of the phages was determined also by a spot test using 8 other clinical bacterial isolates including two reference strains (E. coli ATCC 25922 and S. aureus ATCC 29213). The virulence of the phages and their effects on bacterial growth were assessed by in vitro experiments using E. coli 1642 BBec phage suspension. Results: Isolation of phages by the spot test was positive only with the host E. coli 1642. A reduced host range was observed with the other bacteria. The BBec phage suspension showed a titer of 1.6 x 107 PFU/ml. Virulence studies revealed a latency time of less than 10 minutes, a degree of absorption of 87% and a burst size of 63 PFU/cell. The effect of BBec phage suspension on E. coli 1642 showed an almost total reduction in the population of E. coli 1642 after 4 hours. Conclusion: This study provided scientific data showing the antibacterial effect of a phage suspension (BBec) on a multi-resistant clinical isolate of E. coli 1642. This phage could therefore be explored as a candidate for the development of new antibacterial therapies.

Objectives: To compare the clinical, epidemiological, and laboratory profiles of bacterial infection or colonization among patients hospitalized in COVID-19 and non-COVID-19 intensive care units (ICUs) in Southeast Pará, Brazil. Methods:This was a retrospective analytical study based on the analyses of electronic medical records and microbiological reports of patients admitted to the ICU of a regional hospital located in Pará in the Brazilian Amazon due to complications associated with COVID-19 and other causes from March 2020 to December 2021. The sample consisted of data from the medical records of 343 patients collected after approval by the ethics and research committee (opinion number 5281433) was granted. The data extracted from the bacteriological and antibiogram culture reports were analyzed to characterize the clinical-epidemiological profile of the patients. The data were transferred and tabulated in Microsoft Excel 2019 to conduct a descriptive analysis, and the associated statistical analyses were performed using Stata 17.0 statistical soft-ware. Results: Of the total patients, 59.5% were hospitalized in the COVID-19 ICU and 40.5% were hospitalized in the non-COVID-19 ICU. Most individuals admitted to the COVID-19 ICU and non-COVID-19 ICU were aged between 66 and 78 years and between 54 and 66 years, respectively. The hospitalization duration in the COVID-19 ICU was fewer than 15 days, whereas that in the non-COVID-19 ICU was 15 to 30 days. Deaths were more frequent in the Covid-19 ICU compared to the non-Covid-19 ICU (64% versus 41%). In contrast, hospital discharge was more frequent in the non-Covid-19 ICU (58.3% versus 34.8%).The most prevalent comorbidity in both ICUs was circulatory system disease. Gram-negative bacteria were the most frequent etiological agent in both groups and were present in 63.1% of the cultures analyzed. Regarding the phenotypic profile of resistance, carbapenemase production was detected in 43.0% of the cultures analyzed. Multidrug resistance against antimicrobial drugs was more frequent in the non-COVID-19 ICU (55.7%). Most of the antimicrobial drug prescriptions for were empirical. Conclusions: The recurrence of secondary infections and bacterial colonization in both COVID-19 and non-COVID-19 ICU patients should not be underestimated. The clinical, microbiological, and bacterial resistance profiles elucidated in this study highlight the need to develop and implement holistic and assertive strategies to control and mitigate these problems. Which will contribute to an improved prognosis for patients and quality of life patients (AU).
Objetivos: Comparar o perfil clínico, epidemiológico e laboratorial das infecções ou colonizações bacterianas entre pacientes internados em UTI COVID-19 e não-COVID-19 no Sudeste do Pará, Brasil. Métodos: Trata-se de um estudo analítico retrospectivo baseado na análise de prontuários eletrônicos e laudos microbiológicos de pacientes internados em um hospital regional localizado no Pará, na Amazônia brasileira, devido a complicações associadas à COVID-19 e outras causas no período de março de 2020 a dezembro de 2021. A amostra foi constituída por dados dos prontuários de 343 pacientes coletados após aprovação pelo Comitê de ética em Pesquisa (parecer número 5281433). Os dados extraídos dos laudos de cultura bacteriológica e antibiograma foram analisados para caracterizar o perfil clínico-epidemiológico dos pacientes. Foram realizadas análises descritivas e inferenciais utilizando o Stata 17.0 statistical software. Resultados: Do total de pacientes, 59,5% estavam internados na UTI COVID-19 e 40,5% na UTI não-COVID-19. A maioria dos indivíduos apresentavam idades entre 54 e 78. O tempo de internação na UTI COVID-19 foi inferior a 15 dias, enquanto na UTI não-CO-VID-19 foi de 15 a 30 dias. Os óbitos foram mais frequentes na UTI Covid-19 em relação à UTI não-Covid-19 (64% versus 41%). Em contrapartida, a alta hospitalar foi mais frequente na UTI não Covid-19 (58,3% versus 34,8%). A comorbidade mais prevalente em ambas as UTIs foi a doença do aparelho circulatório. As bactérias Gram-negativas foram os agentes etiológicos mais frequentes em ambos os grupos e estiveram presentes em 63,1% das culturas analisadas. Em relação ao perfil fenotípico de resistência, a produção de carbapenemase foi detectada em 43,0% das culturas analisadas. A multirresistência aos antimicrobianos foi mais frequente na UTI não COVID-19 (55,7%). A maioria das prescrições de antimicrobianos foram empíricas. Conclusões: A recorrência de infecções secundárias e colonizações bacterianas em pacientes com COVID-19 e não COVID-19 em UTIs não devem ser subestimadas. Os perfis de resistência bacteriana elucidados neste estudo destacam a necessidade da implementação de estratégias holísticas e assertivas visando o controle e mitigação dessa problemática, o que contribuirá para a melhoria do prognóstico, bem como, a qualidade e segurança dos paciente (AU).

ABSTRACT
Background & objectives: Multidrug-resistant (MDR) Acinetobacter baumannii is a serious threat for human health worldwide. The studies on agents targeting A. baumannii are imperative due to identified A. baumannii co-infections in COVID-19. Bacteriophages are promising antibacterial agents against drug-resistant bacteria. This study intended to isolate bacteriophages against MDR A. baumannii from the water of river Ganga, to be used potentially as therapeutic and disinfectant particles. Methods: Acinetobacter phages were isolated from the Ganga water collected from Kanpur and further tested on 50 MDR A. baumannii isolates to determine host range. The phages were morphologically characterized by transmission electron microscopy. The disinfectant property of the isolated phages was tested by spraying of bacteriophage cocktail on MDR A. baumannii contaminated plastic surface, analyzed by colony-forming unit (CFU) and bioluminescence assay (adenosine triphosphate monitoring). Results: A total of seven bacteriophages were isolated against MDR A. baumannii. The bacteriophages lysed three MDR A. baumannii isolates out of 50 tested, showing narrow host range. Electron microscopy revealed hexagonal heads and long tails of bacteriophages, belonging to order Caudovirales. The bacteriophage cocktail reduced the MDR A. baumannii load efficiently on plastic surface, evidenced by reduction in CFUs and bioluminescence. Interpretation & conclusions: The findings of this study suggest that the isolated bacteriophages are potential lytic agents for MDR A. baumannii clinical isolates, and may be used as potential therapeutic agents as well as disinfectant to combat MDR A. baumannii with due consideration to phage host specificity, with further characterization.n
ABSTRACT
Este estudo tem por objetivo avaliar a evolução do grau de incapacidade física e do escore olhos, mãos e pés, do diagnóstico à alta medicamentosa, segundo as variáveis sociodemográficas e clínicas, em pacientes diagnosticados com hanseníase. Trata-se de estudo transversal, baseado na análise de 71 pacientes com diagnóstico de hanseníase, acompanhados no Hospital Eduardo de Menezes, centro de referência em Belo Horizonte, Minas Gerais, Brasil, entre janeiro de 2017 a dezembro de 2020. Foi observado predomínio do sexo feminino (53,5%), média de idade de 46 anos, sendo a maioria procedente de outros municípios do interior de Minas Gerais (54,9%). A forma clínica mais frequente foi a dimorfa (64,8%), classificação operacional multibacilar (84,5%). O grau de incapacidade física 0 foi o mais prevalente no diagnóstico (56,5%) e na alta (53,1%), e em relação ao escore olhos, mãos e pés, houve variação entre 0 e 10 no diagnóstico e entre 0 e 8 na alta. Pelo teste de McNemar foi observado que dentre os pacientes que apresentavam algum grau de incapacidade física no momento do diagnóstico, 30,8% apresentaram ausência de incapacidade na alta. Ao comparar a evolução do grau de incapacidade física de paucibacilares e multibacilares no momento do diagnóstico e da alta, houve manutenção em 59,3% e melhora em 17,2% dos pacientes. Os dados apresentados indicam que muitos pacientes foram tratados tardiamente já apresentando as formas graves e com sequelas, já que o estudo foi desenvolvido em um centro de referência, que atende casos mais complexos e com complicações já instaladas. Os dados sugerem que pacientes assistidos que realizam o tratamento com poliquimioterapia podem ter melhora das incapacidades já instaladas. O mesmo ocorreu com o escore olhos, mãos e pés, que ao final do tratamento instituído houve melhora se comparado com a admissão.(AU)
This study aims to evaluate the evolution of the degree of physical disability and the eye, hand and foot score, from diagnosis to medication discharge, according to sociodemographic and clinical variables, in patients diagnosed with leprosy. This is a cross-sectional study, based on the analysis of 71 patients diagnosed with leprosy, followed by Hospital Eduardo de Menezes, a reference center in Belo Horizonte, Minas Gerais, Brazil, between January 2017 and December 2020. There was a predominance of females (53.5%), average age of 46 years old, the majority coming from other municipalities in the interior of Minas Gerais (54.9%). The most frequent clinical form was borderline (64.8%), multibacillary operational classification (84.5%). Degree of physical disability 0 was the most prevalent at diagnosis (56.5%) and at discharge (53.1%); in relation to the eye, hand and foot score, there was variation between 0 and 10 at diagnosis and between 0 and 8 at discharge. By the McNemar test, it was observed that of the patients who had degree of physical disability at the time of diagnosis, 30.8% had no disability at discharge. When comparing the evolution of the GIF in paucibacillary and multibacillary patients at the time of diagnosis and discharge, there was maintenance in 59.3% and improvement in 17.2% of the patients. The presented data indicates that many patients were treated late, already presenting severe forms and with sequelae, since the study was carried out in a reference center, which treats cases with complications already installed and more complex cases. The data suggest that assisted patients undergoing treatment with multidrug therapy may experience improvement in disabilities already established. The same occurred with eye, hand and foot score, at the end of the established treatment there was an improvement compared to admission.(AU)

O objetivo do estudo foi avaliar a percepção dos pacientes quanto ao atendimento nas Redes de Atenção à Saúde, desde o surgimento dos sintomas até o diagnóstico de hanseníase. Trata-se de um estudo qualitativo com 15 pacientes com hanseníase atendidos em um centro de referência no estado do Piauí. A coleta de dados foi realizada entre agosto e setembro de 2022, com o uso de um roteiro de entrevista semiestruturado de três blocos: 1) perfil sociodemográfico e econômico; 2) dados clínicos; e 3) questões semidirigidas relacionadas ao itinerário terapêutico para o diagnóstico e tratamento. Foram incluídos pacientes com hanseníase em tratamento e idade superior a 18 anos. Excluiu-se aqueles que não responderam questionamentos essenciais para os objetivos do estudo ou tangenciaram o tema nesse sentido. Predominaram pacientes mulheres, casadas, com média de idade de 58 anos, ensino fundamental completo, que recebiam menos de um salário-mínimo, autodeclaradas como pardas, residentes em Teresina e com a forma multibacilar da doença. Após a análise de conteúdo, emergiram três categorias temáticas: 1) dificuldades no autorreconhecimento das manifestações clínicas da hanseníase; 2) itinerário terapêutico do usuário com hanseníase na rede de atenção à saúde; e 3) percepção dos pacientes com hanseníase sobre o aten-dimento dos profissionais de saúde. A percepção dos pacientes permite concluir que a busca pelo diagnóstico e o atendimento em saúde foi um processo longo e conflituoso até que estes chegassem a ser atendidos na Atenção Primária.(AU)
The aim of the study was to evaluate patients' perception regarding care in healthcare networks, from the emergence of symptoms to the diagnosis of leprosy. This is a qualitative study with 15 patients with leprosy managed in a referral center in the state of Piauí. Data collection occurred from August to September 2022, with the use of a 3-block semi-structured interview guide: 1) sociodemographic and economic profile; 2) clinical data; and 3) semi-structured questions about the therapeutic itinerary taken for diagnosis and treatment. Included were leprosy patients aged undergoing treatment aged 18 years or above. Excluded were patients who failed to answer questions that were essential to meet study objectives or who barely touched upon the subject. There was a predominance of female, married patients, self-declared as brown (parda), at a mean age of 58 years, with complete elementary school education that earned less than minimum wage and lived in Teresina, with the multibacillary form of disease. After content analysis, three thematic categories emerged: 1) difficulty in self-recognizing the clinical manifestations of leprosy; 2) therapeutic route of the leprosy user in the healthcare network; and 3) perception of leprosy patients about treatment provided by healthcare professionals. The patients' perception allows us to conclude that the search for diagnosis and health care was a long and conflicting process until they reached Primary Care.(AU)

Objective: The goal of this investigation was to look at the frequency and dispersal of bacteria isolated from pus/wound, as well as their susceptibility patterns. Materials and Methods?A study was conducted on 175 patients who provided pus and/or wound discharge samples in different wards (outpatient department or inpatient department). MacConkey agar and blood agar plates were immediately inoculated with samples and incubated at 37°C for 24?hours. The Gram stain and biochemical tests were used to identify all isolates after incubation. Kirby–Bauer's disc diffusion method was used to perform sensitivity tests on Mueller–Hinton agar plates. Results?This study covered 175 patients, with a bacterial isolation rate of 102 (58.28%). Males outnumbered females in the samples (M:F?=?1.8:1), with a median age of 45 years as majority were in the age group of 40 to 60 years which was 41 (40.20%). Total 90.1% samples showed monomicrobial infection, whereas 9.8% showed polymicrobial infection, and total 112 bacterial strains were isolated. Conclusion?Escherichia coli was the most prevalent isolate in present investigation, followed by Pseudomonas aeruginosa. Chloramphenicol is the only antibiotic which is effective for both gram-negative bacilli and gram-positive cocci. This report's susceptibility statistic may be worth considering for developing empiric treatment regimens for pyogenic infections.

Multidrug-resistant Pseudomonas aeruginosa is one of the pathogenic bacteria associated with wound infections. Aim: This study isolated and identified multidrug-resistant Pseudomonas aeruginosa from infected wounds and determine the antibacterial activity of Lawsonia inermis leaf extracts against it. Design: This is a Clinical and laboratory-based study involving patients with defined cases of wound infections. Place and Duration of Study: This study was conducted in the Microbiology (Bacteriology) laboratory of Specialist Hospital, Bauchi, Nigeria, from February to November 2021. Methods: Twenty-eight (28) Pseudomonas aeruginosa isolates were recovered from 179 wound swabs using standard laboratory procedures and were screened for multidrug-resistant patterns according to the Kirby-Bauer disc diffusion method. Antibacterial efficacy of the aqueous, ethanolic, and methanolic leaf extracts of Lawsonia inermis was tested against the multidrug-resistant isolates using agar well diffusion techniques. The zone of inhibition was measured and the differences between means were statistically analyzed (p<0.05). Results: A total of twenty-eight (28) multidrug-resistant Pseudomonas aeruginosa were confirmed, showing resistance to Amoxicillin (64.3%), Ceftazidime (85.71%), and Cefotaxime (78.57%) but sensitivity to Imipenem (95.5%). The phytochemical screening revealed the presence of flavonoids, glycosides, saponins, steroids, and tannins among others. MDR P. aeruginosa was inhibited at varied concentrations of the extracts with the diameter mean zone of inhibition increasing as the concentration increased. The Methanol extracts showed the highest antibacterial activity against MDR P. aeruginosa with a mean zone of inhibition of 9.500±0.288mm at 400mg/ml. Conclusion: These results indicated that Lawsonia inermis leaf extracts possess antibacterial activities on Multidrug-resistant Pseudomonas aeruginosa which could be a good source for the production of plant-based antibacterial drugs., although somewhat less than the synthetic standard drugs (Imipenem) having a mean of 13.83±0.288mm.
ABSTRACT
Background: In endemic regions of several countries, the prevalence of leprosy has not come down to the level of elimination. On the contrary, new cases are being detected in large numbers. Clinically, it is frequently noted that despite completion of multibacillary multidrug therapy for 12 months, the lesions remain active, especially in cases with high bacteriological indices. Aim: The present study focused on finding out the viable number of Mycobacterium leprae during the 12-month regimen of multibacillary multidrug therapy, at six and 12 months intervals and, attempting to determine their role in disease transmission. Methods: Seventy eight cases of multibacillary leprosy cases were recruited from leprosy patients registered at The Leprosy Mission hospitals at Shahdara (Delhi), Naini (Uttar Pradesh) and Champa (Chhattisgarh), respectively. Slit skin smears were collected from these patients which were transported to the laboratory for further processing. Ribonucleic acid was extracted by TRIzol method. Total Ribonucleic acid was used for real-time reverse transcription-polymerase chain reaction (two-step reactions). A standard sample with a known copy number was run along with unknown samples for a reverse transcription-polymerase chain reaction. Patients were further assessed for their clinical and molecular parameters during 6th month and 12th month of therapy. Results: All 78 new cases showed the presence of a viable load of bacilli at the time of recruitment, but we were able to follow up only on 36 of these patients for one year. Among these, using three different genes, 20/36 for esxA, 22/36 for hsp18 and 24/36 for 16S rRNA cases showed viability of M. leprae at the time of completion of 12 months of multidrug therapy treatment. All these positive patients were histopathologically active and had bacillary indexes ranging between 3+ and 4+. Patients with a high copy number of the Mycobacterium leprae gene, even after completion of treatment as per WHO recommended fixed-dose multidrug therapy, indicated the presence of live bacilli. Limitations: Follow up for one year was difficult, especially in Delhi because of the migratory nature of the population. Patients who defaulted for scheduled sampling were not included in the study. Conclusion: The presence of a viable load of bacilli even after completion of therapy may be one of the reasons for relapse and continued transmission of leprosy in the community
ABSTRACT
Background: Increasing bacterial resistance to antimicrobial agents is resulting in high morbidity and mortality. Antimicrobial stewardship (AMS) programs aim at rationale use of antimicrobial agents in clinical settings by development and implementation of antibiotic policy. As the patterns of antimicrobial resistance vary with organism and time, there is a need for periodic surveillance. Aims and Objectives: The aim of the study was to study the impact of AMS program on appropriate use of antimicrobial agents and clinical outcomes in patients with multidrug-resistant Gram-negative bacterial (MDR GNB) infections. Materials and Methods: This is a prospective observational study that included patients diagnosed with multidrug-resistance Gram-negative bacterial infections during June to July 2019. Identification of multidrug-resistant organisms was performed as per clinical and laboratory standards institute guidelines 2016. Information on the use of empirical antibiotic and other antimicrobial agents after culture and sensitivity report were collected and assessed for appropriateness. All the patients were followed up till discharge. Results: From 170 patients, there were 211 specimens sent for culture and sensitivity and 249 pathogens were isolated. The most frequent pathogen isolated was Escherichia coli (42.6%) followed by Klebsiella spp. (22.9%). Isolates were most resistant to cefazolin (86.7%) and ceftriaxone (83.9%), and most sensitive to polymyxin B (100%) and tigecycline (97.2%). All patients were administered antimicrobial agents as per antibiotic policy of the institute and 154 (90.6%) patients have recovered from illness with a mean length of hospital stay of 19.4 ± 6.6 days. Conclusion: Adherence to antimicrobial policy helps in improved outcomes in patients with MDR GNB infections. Hence, the need to implement AMS program in all hospitals.
ABSTRACT
Resumen El abuso y mal uso de los antimicrobianos aceleró la propagación de bacterias resistentes. La asociación entre las infecciones que presentan resistencia a antimicrobianos (RAM) en humanos y el uso de antimicrobianos en la producción agropecuaria es compleja, pero está bien documentada. Proporcionamos una revisión sistemática y metaanálisis sobre la diseminación de la resistencia a antimicrobianos designados como críticamente importantes por la Organización Mundial de la Salud (OMS) en cerdos, aves y bovinos de producción intensiva y extensiva en Argentina. Se buscó información en bases de datos electrónicas (Medline-PubMed, Web of Science, SciELO, Sistema Nacional de Repositorios Digitales de Argentina) y en la literatura gris. Se incluyeron estudios epidemiológicos sobre la RAM en las principales bacterias transmitidas por los alimentos - Salmonella spp., Campylobacter spp., Escherichia coli y Enterococcus spp. - y bacterias causantes de mastitis aisladas de cerdos, pollos y bovinos. Los resultados de este estudio apoyan la hipótesis de que la RAM de las bacterias transmitidas por los alimentos alcanza niveles alarmantes. Los metaanálisis seguidos de análisis por subgrupos mostraron asociación entre la RAM y (a) el animal (p<0,01) para estreptomicina, ampicilina y tetraciclina o (b) el sistema productivo (p<0,05) para estreptomicina, cefotaxima, ampicilina, ácido nalidíxico y tetraciclina. La mayor prevalencia conjunta de multirresistencia se detectó en cerdos (0,47 [0,29; 0,66]) y producción intensiva (0,62 [0,34; 0,83]), mientras que la menor correspondió a bovinos de leche (0,056 [0,003; 0,524]) y producción extensiva (0,107 [0,043; 0,240]). Se observó un vacío de información respecto de los bovinos de feedlot. Es urgente adoptar medidas políticas para coordinar y armonizar la vigilancia de la RAM y regular el uso de antimicrobianos en animales.
Abstract Abuse and misuse of antimicrobial agents has accelerated the spread of antimicrobial-resistant bacteria. The association between antimicrobial-resistant infections in humans and antimicrobial use in agriculture is complex, but well-documented. This study provides a systematic review and meta-analysis of the dissemination of antimicrobial resistance (AMR) to antimicrobials defined as critically important by the WHO, in swine, chicken, and cattle from intensive and extensive production systems in Argentina. We conducted searches in electronic databases (MEDLINE-PubMed, Web of Science, SciELO, the National System of Digital Repositories from Argentina) as well as in the gray literature. Inclusion criteria were epidemiological studies on AMR in the main food-transmitted bacteria, Salmonella spp., Campylobacter spp., Escherichia coli and Enterococcus spp., and mastitis-causing bacteria, isolated from swine, chicken, dairy and beef cattle from Argentina. This study gives evidence for supporting the hypothesis that AMR of common food-transmitted bacteria in Argentina is reaching alarming levels. Meta-analyses followed by subgroup analyses confirmed the association between the prevalence of AMR and (a) animal species (p<0.01) for streptomycin, ampicillin and tetracycline or (b) the animal production system (p<0.05) for streptomycin, cefotaxime, nalidixic acid, ampicillin and tetracycline. Moreover, swine (0.47 [0.29; 0.66]) and intensive production (0.62 [0.34; 0.83]) showed the highest pooled prevalence of multidrug resistance while dairy (0.056 [0.003; 0.524]) and extensive production (0.107 [0.043; 0.240]) showed the lowest. A research gap regarding beef-cattle from feedlot was identified. Finally, there is an urgent need for political measures meant to coordinate and harmonize AMR surveillance and regulate antimicrobial use in animal production.

Estudio transversal realizado a través de un análisis secundario de la base de datos de una cohorte de tuberculosis, que incluyó datos de pruebas antropométricas y pruebas de sensibilidad a drogas en la visita basal de pacientes con y sin tratamiento previo para tuberculosis. Resultados. Se evaluaron 3,734 casos nuevos y 766 con antecedente de haber recibido tratamiento para tuberculosis. El sobrepeso/obesidad no se asoció a la multidrogoresistencia en pacientes con antecedente de tratamiento para tuberculosis, mostrando una razón de prevalencia de 0,97 con un intervalo de confianza al 95% de 0,68-1,38. Conclusiones. El sobrepeso/obesidad no está asociado a la multidrogoresistencia en tuberculosis; siendo el sobrepeso/obesidad un proceso dinámico que puede influir en las relaciones entre el sistema inmune y el sistema metabólico.
Objective. To evaluate the association between overweight/obesity and multidrug resistance in patients with and without a history of tuberculosis treatment. Materials and methods. Cross-sectional study of secondary data from a tuberculosis cohort, which included anthropometric and drug-sensitivity testing data at the baseline visit of patients with and without previous tuberculosis treatment. Results. We evaluated 3,734 new cases and 766 with a history of having received treatment for tuberculosis. Overweight/obesity was not associated with multidrug resistance in patients with a history of tuberculosis treatment, with a prevalence ratio of 0.97 and a 95% confidence interval of 0.68-1.38. Conclusions. Overweight/obesity is not associated with multidrug resistance in tuberculosis. Overweight/obesity is a dynamic process that may influence the relationship between the immune system and the metabolic system.

OBJECTIVE@#To investigate the efficacy and safety of colistin sulfate in the treatment of hematonosis patients infected by multidrug-resistant (MDR) gram-negative bacteria (GNB), and discuss the possible factors that affect the efficacy of colistin sulfate.@*METHODS@#The clinical data of 85 hematologic patients infected with MDR GNB in the Soochow Hopes Hematonosis Hospital from April 2022 to November 2022 were collected and divided into clinically effective group with 71 cases and ineffective group with 14 cases according to the therapeutic efficacy of colistin sulfate. The age, gender, type of hematologic disease, status of hematopoietic stem cell transplantation, infection sites, type of pathogen, timing of administration, daily dose and duration of colistin sulfate, and combination with other antibacterial agents of patients in two groups were compared. Logistic regression was used to analyze on the meaningful variables to study the influencing factors of colistin sulfate. The adverse reactions of colistin sulfate were also evaluated.@*RESULTS@#There were no significant differences in age, gender, type of hematologic disease, hematopoietic stem cell transplantation status, infection sites and pathogen type between the effective group and the ineffective group (P>0.05). Compared with the medication time more than 7 days, meropenem used within 7 days in the clinical effective group, and timely replacement with colistin sulfate could obtain better efficacy, the difference was statistically significant (P=0.018). The duration of tigacycline before colistin sulfate did not affect the efficacy, and there was no significant difference in efficacy between the effective and ineffective groups. The therapeutic effect of colistin sulfate at daily dose of 500 000 U q8h was better than that of 500 000 U q12h, the difference was statistically significant (P=0.035). The time of colistin sulfate use in the clinically effective group was longer than that in the ineffective group, which had a statistical difference (P=0.003). Compared with the clinical ineffective group, the efficacy of combination regimens with colistin sulfate was better than that of colistin sulfate monotherapy, and the difference was statistically significant (P=0.013). Multivariate logistic regression analysis was performed on the indicators with statistical differences in the two groups of patients, which suggested that the use time of colistin sulfate (B: 2.358; OR: 10.573; CI: 1.567-71.361; P=0.015) and the combination of colistin sulfate (B: 1.720; OR: 5.586; CI: 1.210-25.787; P=0.028) were influential factors in the efficacy of colistin sulfate. During the treatment, the incidence of nephrotoxicity, hepatotoxicity and peripheral neurotoxicity were 5.9%, 1.2% and 1.2%, respectively.@*CONCLUSION@#The use of colistin sulfate improves the clinical efficacy of MDR GNB infections in hematological patients, and the timing of colistin sulfate administration and the combination of drugs are independent factors affecting its clinical efficacy, and the safety during treatment is high.
