Patients with chronic urinary and urogenital multidrug resistant bacterial infections received phage therapy (PT) using intravesical or intravesical and intravaginal phage administration. A single course of PT did not induce significant serum antibody responses against administered phage. Whilst the second cycle of PT caused a significant increase in antibody levels, they nevertheless remained quite low. These data combined with good therapy results achieved in some patients suggest that this mode of PT may be an efficient means of therapy for urogenital infections and a reliable model for a clinical trial of PT.

Introduction: Systemic bacterial infections are a common cause of mortality and morbidity in hemodialysis patients. Zinc has a critical role in several immune system functions. Patients who have enough amounts of zinc are able to better face infections caused by various pathogens in comparison to those with zinc insufficiency Objective We sought to assess the role of zinc deficiency in dialysis-associated bacterial infections. Patients and Methods: Eighty-Three adult patients with end-stage renal disease (ESRD) on hemodialysis including 43 patients with bacterial infectious complications and 40 non-infected patients as well as 41 healthy individuals were enrolled. Clinical data, laboratory values including serum zinc level and imaging findings were collected. SPSS was utilized to analyze the data with a significance cutoff set at P < 0.05. Results: Out of 124 participants, 80 (64.51%) were males and 44 (35.49%) were females. The mean age of infected hemodialysis group, non-infected hemodialysis group, and healthy controls were 50.8 ± 16.25, 49.1 ± 18.1, and 56.3 ± 18.2 years, respectively. Catheter site infection (37.3%) and urinary tract infection (30.2%) were the most common infections. The mean serum zinc concentration was significantly lower in the infected patients, compared to non-infected patients and healthy individuals (P < 0.001). Conclusion: The ESRD patients on hemodialysis have lower serum zinc levels which are associated with increased risk of bacterial infection. The role of screening for zinc deficiency and use of supplemental zinc in these patients need to be studied.

Powerful Strategy

Various bacterial pathogens are responsible for nosocomial infections resulting in critical pathophysiological conditions, mortality, and morbidity. Most of the bacterial infections are associated with biofilm formation, which is resistant to the available antimicrobial drugs. As a result, novel bactericidal agents need to be fabricated, which can effectively combat the biofilm-associated bacterial infections. Herein, for the first time we report the antimicrobial and antibiofilm properties of silver-platinum nanohybrids (AgPtNHs), silver nanoparticles (AgNPs), and platinum nanoparticles (PtNPs) against Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus. The AgPtNHs were synthesized by a green route using Dioscorea bulbifera tuber extract at 100°C for 5 h. The AgPtNHs ranged in size from 20 to 80 nm, with an average of ∼59 nm. AgNPs, PtNPs, and AgPtNHs showed a zeta potential of −14.46, −1.09, and −11.39 mV, respectively. High antimicrobial activity was observed against P. aeruginosa and S. aureus and AgPtNHs exhibited potent antimicrobial synergy in combination with antibiotics such as streptomycin, rifampicin, chloramphenicol, novobiocin, and ampicillin up to variable degrees. Interestingly, AgPtNHs could inhibit bacterial biofilm formation significantly. Hence, co-administration of AgPtNHs and antibiotics may serve as a powerful strategy to treat bacterial infections.

Background: Opportunistic bacterial infections remain a serious morbidity among cancer patients. This study was aimed to determine the bacteriological and antibiotic profile of cancer patients admitted to the ICU of a tertiary care centre.Methods: Cross sectional study was done among cancer patients admitted in the Oncology neutropenic ICU during the period from August 2017 to July 2019. All patients admitted with a proven diagnosis of cancer for whom at least one bacterial culture was sent from any site were included in the study. Laboratory on culture reports were obtained from patient files and analysed.Results: A total of 278 samples from 256 patients (60±11.6 years) were analysed. Among the 111/278 positive cultures, 29 were blood samples and 1 was a pleural fluid sample. Gram negative organisms were 62.1% with Escherichia coli (25, 36.2%) as prevalent. Among the 37.8% gram positives, Staphylococcus aureus (18. 42.8%) was prevalent. Most of the E. coli strains showed highest resistance to ceftazidime (96%) and highest sensitivity to amikacin. The commonest gram-positive organism, Staphylococcus species were 100 % sensitive to vancomycin and linezolid and 100 % resistance to penicillin.  Conclusions: E. coli (gram negative) showed highest resistance to ceftazidime and sensitivity to amikacin. S. aureus (gram positive) was sensitive to vancomycin and linezolid and resistance to penicillin. An antibiogram for cancer patients helps the clinician to initiate an appropriate empirical antibiotic therapy to reduce mortality and morbidity.

Abstract Background: Severe acute respiratory syndrome COVID-19 infection has evolved into a global pandemic. This study has been designed to evaluate colchicine anti-inflammatory effect on the symptoms course, duration of hospitalization, morbidity and mortality rate, of COVID-19 patients.Methods: In this prospective, open-label, randomized and double blind clinical trial, 100 patients hospitalized with COVID-19 were randomized in a 1:1 allocation from May 21 to June 20, 2020, to either standard medical treatment (Hydroxychloroquine) or colchicine with standard medical treatment. The study took place in Imam Reza hospital of Ardabil city in Iran, with trial registration ID: 47707 (irct.ir). Colchicine group were received 1 mg tablet of colchicine daily alongside the Hydroxychloroquine for 6 days. Primary end points were (1) Length of hospitalization; (2) symptoms and (3) Co-existed disease. Secondary end points were examined 2 weeks after discharge and included (1) mortality and morbidity; (2) re-admission and (3) symptoms. Results: Overall, 100 patients (59 [59%] female; median age, 56 years) fulfilled the admission criteria and were included and randomized at 2 clinical groups. There was no significant difference between the two groups in terms of age and sex. Two groups were not significantly different in terms of underlying diseases and various clinical and para clinical findings although there were not any different during Post-discharge follow-up except for duration of fever (P<0.05). Comparing two groups showed significantly different only in the duration of hospitalized (P<0.05). Although in colchicine group dyspnea was improved more rapid than the placebo group, but it was not meaningful. Conclusion: Colchicine can be effective in reducing systemic symptoms of COVID-19 by inhibiting inflammatory biomarkers.Current Controlled prospective Trials registration ID that has been approved by ICMJE and WHO ICTRP registry is IRCT20200418047126N1, and the date of registration is 2020-05-14.

The menace of multidrug resistance among bacterial infections is an issue of global public health. Treatment of these superbugs with first line antibiotics is associated with significant treatment failure leading to increased mortality and morbidity. Carbapenems and polymyxins are the saviour antibiotics in case of such infections. But the problem is compounded when these antimicrobials also fail. The addition of beta-lactamase inhibitor like sulbactam and disodium ethylenediaminetetraacetic acid broaden the in vitro antibacterial action of ceftriaxone. This novel combination has been found to be effective in most of the drug resistant bacterial strains.

Sthaulya / Atisthaulya in Ayurveda comes under the heading of Medoroga which results due to dysfunc-tion of Meda Dhatvagni (factor responsible for nourishment / metabolism of Meda dhatu) and in modern parlance it is equated with Obesity due to its close similarities. It is the main cause for so many complica-tions like Hypertension, Diabetes mellitus, Osteoarthritis, Infertility, Impotency etc. as well as psychologi-cal disturbances like anxiety, depression etc. Thus, the mortality and morbidity rate were high in obese per-sons compared to others. This shows the importance of the need for further researches of effective measures in the management of Sthaulya. Hence in the present study a clinical trial was carried out with Trikatu Churna in the management of Sthaulya (obesity) for 30 days. 30 patients were selected with diag-nosis of Sthaulya out of which 24 completed the treatment. The study concluded with the positive results of Trikatu churna in reducing the signs and symptoms of Sthaulya.

Abstract BackgroundPopulation aging will be one of humanity’s major challenges in the decades to come. In addition to focusing on the pathologies causing the greatest mortality and morbidity in this population, such as dementia, health research in elderly people must consider a myriad of other interlinked factors, such as geriatric syndromes, social aspects, and factors related to preserving quality of life and promoting healthy aging. This study aims to identify the main subject areas attracting research attention with regard to very old (≥ 80 years) populations.MethodsDocuments assigned with the medical subject heading “Aged, 80 and over” were retrieved from MEDLINE and the Web of Science. This dataset was used to determine publication output by disease, geographic region, country, and discipline. A co-word analysis was undertaken to identify thematic research clusters.ResultsSince the mid-2000s, there has been a boom in scientific output focusing specifically on very old populations, especially in Europe (43.7% of the documents) but also in North America (30.5%) and Asia (26%); other regions made only nominal contributions (0.5% to 4.4%). The USA produced the most research, while the most growth over the study period occurred in Japan, Spain, and China. Four broad thematic clusters were identified: a) geriatric diseases, health services for the aged, and social and psychological issues of aging; b) cardiovascular diseases; c) neoplasms, and d) bacterial infections & anti-bacterial agents.ConclusionsScientific research in very old populations covers a wide variety of interrelated topics. In quantitative terms, the top subject areas have to do with cardiovascular and cerebrovascular diseases (including aortic valve stenosis and stroke), dementia, and neoplasms. However, other degenerative pathologies, geriatric syndromes, and different social and psychosocial aspects also attract considerable interest. It is necessary to promote more equal participation in global research on pathologies and topics related to very elderly populations, as the highest rates of population aging and the largest numbers of elderly people in the next decades will be in low- and middle-income countries.

Of all the medications available to physicians worldwide, antibiotics play an essential role in inpatient and outpatient settings. Discovered in the early nineteenth century by Alexander Fleming, penicillin was the first antibiotic isolated from a mold. Dr. Gerhard Domagk developed synthetic sulfa drugs by altering the red dye used in chemical industries. Since then, multiple antibiotic classes have been discovered with varying antimicrobial effects enabling their use empirically or in specific clinical scenarios. Antibiotics with different mechanisms of action could be either bactericidal or bacteriostatic. However, no clinical significance has been observed between cidal and static antibiotics in multiple trials. Their presence has led to safer deep invasive surgeries, advanced chemotherapy in cancer, and organ transplantation. Indiscriminate usage of antibiotics has resulted in severe hospital-acquired infections, including nosocomial pneumonia, Clostridioides difficile infection, multidrug-resistant invasive bacterial infections, allergic reactions, and other significant side effects. Antibiotic stewardship is an essential process in the modern era to advocate judicial use of antibiotics for an appropriate duration. They play a vital role in medical and surgical intensive care units to address the various complications seen in these patients. Antibiotics are crucial in severe acute infections to improve overall mortality and morbidity.
