RESUMO
Health professionals and medical students are at increased risk of the imposter phenomenon (IP) in other words, the imposter syndrome, due to the challenging nature of their professions. It is particularly concerning since it is linked to a higher incidence of burnout and suicidal ideation. We must first thoroughly grasp its prevalence and associated factors to address this issue. However, no published review of the data includes a meta-analysis to help understand the character and associated factors of IP among medical workers and medical students. This study aims to investigate IP prevalence and risk factors among healthcare personnel. Five online databases will be searched for papers published in English between January 2000 and December 2022, and 2 independent reviewers will filter, select studies, extract data, and evaluate the risk of bias in each piece. The retrieved articles will be included based on strict inclusion and exclusion criteria. A third reviewer will decide on any disagreements between the 2 reviewers. Where appropriate, a meta-analysis will be conducted using the random-effects model. The heterogeneity of the studies will be examined, and a sensitivity analysis will be done depending on the study quality. The purpose of this review is to determine the prevalence and risk factors for IP among healthcare personnel. The review's findings will emphasize the severity and contributing factors of the problem, therefore guiding policy for future actions.

Importance: Urinary tract infection (UTI) is one of the most common infections encountered in infancy and childhood. Despite the emerging problem of antibiotic resistance in recent years, the use of antibiotics for better management of UTIs is inevitable. Objective: This study aims to explore the efficacy and adverse effects of the available antimicrobial agents that are used in pediatric UTIs in low- and middle-income countries (LMICs). Methods: Five electronic databases were searched to identify relevant articles. Two reviewers independently performed screening, data extraction, and quality assessment of the available literature. Randomized controlled trials providing antimicrobial interventions in both male and female participants within the age range of 3 months to 17 years in LMICs were included. Results: Six randomized controlled trials from 13 LMICs were included in this review (four trials explored the efficacy). Due to high heterogeneity across the studies, a meta-analysis was not performed. Other than attrition and reporting bias, the risk of bias was moderate to high due to poor study designs. The differences in the efficacy and adverse events of different antimicrobials were not found to be statistically significant. Interpretation: This review indicates the necessity for additional clinical trials on children from LMICs with more significant sample numbers, adequate intervention periods, and study design.
RESUMO
BACKGROUND: Cryptosporidium spp. are responsible for significant diarrheal morbidity and mortality in under-5 children. There is no vaccine; thus, a focus on prevention is paramount. Prior studies suggest that person-to-person spread may be an important pathway for transmission to young children. Here we describe a longitudinal cohort study of 100 families with infants to determine rates of cryptosporidiosis within households during the coronavirus disease 2019 (COVID-19) pandemic. METHODS: Families living in Mirpur, Bangladesh, with 1 infant aged 6-8 months were enrolled and followed with weekly illness survey and stool testing for Cryptosporidium for 8 months. RESULTS: From December 2020 to August 2021, 100 families were enrolled. Forty-four percent of index children and 35% of siblings had at least 1 Cryptosporidium infection. Shedding of Cryptosporidium occurred for a mean (standard deviation) of 19 (8.3) days in index infants, 16.1 (11.6) days in children 1-5 years, and 16.2 (12.8) days in adults. A longer duration of Cryptosporidium shedding was associated with growth faltering in infants. There was a spike in Cryptosporidium cases in May 2021, which coincided with a spike in severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) cases in the region. CONCLUSIONS: In this intensive, longitudinal study of Cryptosporidium infection in families we found high rates of cryptosporidiosis in infants and children, and prolonged parasite shedding, especially among malnourished children. These data support that transmission within the household is an important route of exposure for young infants and that treatment of nondiarrheal infection to interrupt person-to-person transmission within the home may be essential for preventing cryptosporidiosis in infants.

We followed 100 families with infants living in Bangladesh and studied the incidence of Cryptosporidium infection. We found prolonged Cryptosporidium shedding in stool was common among infants and adults.
RESUMO
BACKGROUND: Persistent kidney illness in children and those on dialysis therapy, risk of vitamin and mineral deficiencies due to abnormal renal metabolism, anorexia, inadequate intake, poor gastrointestinal absorption, drug-nutrient interaction, and dialysis-related losses. Adequate nutritional management is essential to achieve and maintain an optimal nutritional status for the usual pattern of growth, sexual and neurocognitive development, metabolic abnormalities, and ultimately reducing the risk of chronic mortality and morbidity in adulthood. The purpose of this paper is to describe a protocol for a systematic review to assess the effects of vitamin and mineral supplementation in children with chronic renal disease. METHODS: This systematic review protocol is developed according to the Preferred Reporting Item for Systematic Review and Meta-Analysis Protocols (PRISMA-P) as well as the Cochrane group guidelines. Comprehensive searching for all possible relevant works of literature- such as PubMed, Google Scholar, MEDLINE, Embase, Web of Science, Cochrane Central Register of Controlled Trials (CENTRAL), Science-Direct, Scopus, Research-Gate, Clinical Trials for all randomized controlled studies, full paper articles, and articles written in English will be considered. The primary outcome of this review will be measuring any changes (such as changes in body mass, BMI, and overall Z-score) in the nutritional status of the children (ageâ <â 18 years) with chronic kidney disease following vitamin and mineral supplementations. This review will help better understand the effects of vitamin and mineral supplementation to improve nutritional status in CKD children and will create a guideline to determine the applicability of these interventions in different feasible settings. CONCLUSION: The systematic review protocol has been evaluated and approved by the institutional review board of North South University. Finding will be shared using traditional approaches, including scientific presentations, open-access peer-reviewed platforms. PROSPERO REGISTERED NUMBER: CRD42022341339.

Background and objectives: Abnormal uterine bleeding is a significant clinical and gynaecological concern that necessitates its safe and effective treatment. The present study aims to compare the cost-effectiveness, safety, efficacy, and health-related quality of life of ormeloxifene with medroxyprogesterone acetate in women with non-structural abnormal uterine bleeding. Materials and Methods: A prospective, randomized, single-blinded clinical trial of 367 patients was carried out at a tertiary care hospital for a period of one year from 5 January 2019 to 4 January 2020. Patients were randomized into two groups for administering ormeloxifene and medroxyprogesterone acetate for a 3-month treatment duration and were evaluated by laboratorial investigations like anaemic status, bleeding duration, endometrial thickness, pictorial blood loss assessment chart (PBLAC) score, and patient's medical and medication history. Health-related quality of life was assessed using short form survey-36 (SF-36) questionnaire scale. Cost-effectiveness was determined on the basis of the three-month treatment regimen. Results: The mean duration of bleeding reduced from 16.88 ± 6.46 to 7.76 ± 1.55 in the ormeloxifene group and from 15.91 ± 5.04 to 8.7 ± 1.91 (p < 0.001) in the medroxyprogesterone acetate. Similarly, mean haemoglobin increased from 8.56 ± 0.77 to 10.1 ± 0.087 g/dL and from 8.60 ±0.97 to 9.551 ± 0.90 g/dL (p < 0.001), and endometrial thickness showed a reduction from 8.52 ± 1.61 mm to 6.92 ± 1.68 mm and from 8.40 ± 2.09 mm to 7.85 ± 2.0 mm (p < 0.001) in the ormeloxifene and medroxyprogesterone acetate groups, respectively. PBLAC score reduced from 289.92 ± 42.39 to 128.11 ± 33.10 and from 287.38 ± 40.94 to 123.5 ± 29.57 (p < 0.001) in these groups, respectively. Health-related quality of life improved in the ormeloxifene group more than the medroxyprogesterone group, which was evidenced by SF-36 scale parameters (physical function, energy/fatigue and pain) that changed from 24.39, 12.99, 6.25 to 28.95, 18, 9 and from 25.41, 13.6, 7.1 to 27.02, 16, 8.3 in the ormeloxifene and medroxyprogesterone acetate groups, respectively. Conclusions: The study concludes that both medroxyprogesterone acetate and ormeloxifene are safe and efficacious in controlling abnormal uterine bleeding, but ormeloxifene was the better of the two in terms of cost effectiveness, reduction in pictorial blood loss assessment score, endometrial thickness, bleeding duration (days), increase in haemoglobin concentration (g/dL) and improvement in the quality of life.

The emerging concept of planetary health needs to be discussed in a more organized and sustainable way within the global public health and healthcare disciplines. Therefore, planetary health should be considered a cardinal component of the global academic framework for healthcare professionals. The availability of related curricula and courses is crucial to equip health professionals in this relatively new discipline of planetary health. In this review article, we aimed to explore published articles and online databases of courses to summarize the available planetary health education opportunities and discussions for health professionals, to identify the gaps in resource allocation and to suggest future recommendations. We observed a visible resource inequity in the global south with the lack of a universal planetary health module for healthcare professionals. Additionally, there is minimal inclusion of allied health disciplines in this learning process. We therefore recommend a dedicated network of motivated healthcare professionals and regional hubs with an agenda to ensure a comprehensive, uniform, and inclusive planetary health education curriculum and practice.

Following the worldwide COVID-19 pandemic, individuals have begun to take preventive measures to avoid exposure. Among the precautionary measures, facemask was mostly emphasized. This study aimed to determine the prevalence of dermatological symptoms linked with face mask usage and explore other associated factors. This cross-sectional survey was conducted throughout all eight divisions of Bangladesh. 1297 people were approached using a fixed-step procedure on a random route sample where 803 fulfilled the inclusion criteria. The overall prevalence of dermatological manifestation in this study was 40.85%. The common dermatological manifestations due to facemasks use were acne (26%), allergy symptoms (24%), traumatic symptoms (24%), and other symptoms (26%). Two important frequently reported risk factors were previous history of skin diseases and obesity. Females were more likely to have acne (CI: 1.199, 3.098; p = .007) and allergy issues (CI: 1.042, 2.359; p = .031). N95 and KN95 masks were more likely to produce allergic symptoms, while surgical mask users were more likely to develop acne. Acne was prevalent more than twice (CI: 1.42, 4.26; p = 0.001) in persons with a COVID-19 infection history. Further exploration is required to find out the reason. Surgical mask users reported more complaints than other types of masks, and prolonged use caused more skin symptoms. Modifications in the pattern of facemask usage and planning for work recesses might also be advised to provide for a pause from uninterrupted facemask use.

INTRODUCTION: Urinary tract infection (UTI) is a frequently diagnosed infection in women and children. Treatments are often initiated with broad-spectrum antibiotics without performing any culture and sensitivity test. Inappropriate and empirical antimicrobial regimens and poor adherence to the drugs lead to the recurrence of the disease. Moreover, resistance against antibiotics in the urinary tract bacteria due to inadequate therapies is a more significant cause of concern. This systematic review will explore the different antimicrobial options for treating UTIs in children and compare their effectiveness. METHODS AND ANALYSIS: Four electronic databases MEDLINE, Cochrane Central Register of Controlled Trials, Scopus and Web of Science will be searched in February 2022 to find relevant studies. After the initial screening by two independent review authors, the selected articles will go through the full-text evaluation to filter the inclusion criteria. Using an appropriate tool, the risk of bias will also be assessed by two independent review authors. The review results showing the treatment effects of different antimicrobials will be presented as a narrative synthesis, and a meta-analysis will be conducted if applicable. Assessment of heterogeneity between studies, assessment of publication bias, and sensitivity analysis will also be performed. ETHICS AND DISSEMINATION: The study protocol of this systematic review has been approved by the institutional review board of North South University. The dissemination of the results will be conducted in the form of scientific publication in a peer-reviewed journal and presentations in different regional and international conferences. PROSPERO REGISTRATION NUMBER: CRD42021260415.

PURPOSE: Sexually transmitted infections are a major worldwide concern, and human papillomavirus (HPV) is one of the significant risk factors. Many populations suffer from various diseases caused by HPV, and the overall death toll due to cervical carcinoma is remarkable. Despite vaccine availability, perception about vaccine safety and efficacy, its' preventive outcome is still inferior among the health professionals and vaccine providers. So, this study aims to assess the knowledge, attitude, and practice level of HPV and its' vaccination among doctors, dentists, and medical students. MATERIALS AND METHODS: This cross-sectional survey was carried out between April to August 2021, where 626 participants from all types of medical institutions of Bangladesh were interviewed using a validated and structured questionnaire that consists of four extensive areas; socio-demographic characteristics, HPV knowledge, attitude, and practices regarding vaccination. RESULTS: The knowledge and practice standards showed very poor outcomes where 43.29% of the participants showed good knowledge and only 11.82% conveyed good practices. Nevertheless, the attitude towards HPV vaccination was revealed high (75.88%). Female participants showed more positive attitudes than males. CONCLUSION: Physicians and dentists play vital roles in raising public knowledge about HPV and awareness regarding HPV vaccination programs. The provision of medical education on HPV must be prioritized, and current training techniques must be re-evaluated. Thus, by implementing this strategy, improvement in national vaccination policy can be expected.
RESUMO
Polycystic ovary syndrome (PCOS), the most common endocrinopathy in women is characterized by polycystic ovaries, chronic anovulation and hyperandrogenism. The treatment in PCOS is mainly symptomatic and involves lifestyle interventions and medications such as Metformin, Oral contraceptives and Antiandrogens. However, the management of PCOS is challenging and current interventions are not able to deal with outcomes of this syndrome. This review encompasses latest pharmacotherapeutic and non-pharmacotherapeutic interventions currently in use to tackle various symptomatic contentions in PCOS. Our focus has been mainly on novel therapeutic modalities for treatment/management of PCOS, like use of newer insulin sensitizers viz., Inositols, Glucagon-like peptide-1(GLP-1) agonists, Dipeptidyl pepdidase-4 (DPP-4) inhibitors, and sodium-glucose transport protein 2 (SGLT2) inhibitors. Also, evidence suggesting the use of vitamin D, statins, and Letrozole as emerging therapies in PCOS have been summarized in this review. Additionally, novel cosmetic techniques like electrolysis, laser and use of topically applied eflornithine to tackle the most distressing feature of facial hirsutism associated with PCOS, non-pharmacological therapy like acupuncture and the role of herbal medicine in PCOS management have also been discussed.

BACKGROUND: Frailty syndrome is a medical condition defined by a progressive loss of function that usually begins beyond 65 and necessitates assistance with daily activities. There are both pharmacological and nonpharmacological approaches to prevent frailty. The purpose of this systematic review is to investigate viable nonpharmacological therapies for reducing frailty among the elderly in low- and middle-income countries, to develop an appropriate guideline to determine the applicability of these nonpharmacological interventions in various feasible settings. METHODS: Two independent researchers will explore 5 electronic databases for relevant and promising studies. The selected articles will be subjected to a full-text examination following the initial screening. Two independent authors will analyze the risk of bias using the Cochrane risk of bias assessment tool. The review findings on various nonpharmacological approaches to prevent frailty will be presented as a narrative synthesis. There will be a sensitivity analysis and an assessment of study heterogeneity if possible. RESULTS AND CONCLUSION: The systematic review protocol has been evaluated and approved by the institutional review board of North South University. The preferred reporting items for systematic review and meta-analysis protocol recommendations for precisely reporting health care interventions and the Cochrane group standards will be strictly followed in this systematic review protocol.

BACKGROUND: Despite the availability and success of live-attenuated oral vaccines, rotavirus (RV) remains the leading cause of pediatric gastroenteritis worldwide. Next-generation vaccines targeting RV VP8∗ are under evaluation, but the role of VP8∗-specific antibodies in human immunity to RV and their potential as immune correlates of protection remains underexplored. METHODS: We measured plasma RV VP8∗-binding antibodies in 2 cohorts of young children in Dhaka, Bangladesh. Plasma from a cohort study of 137 unvaccinated children aged 6-24 months old hospitalized with acute gastroenteritis was assessed for VP8∗ antibody seropositivity. VP8∗ antibodies were compared with the current standard for RV immunity, total RV-specific IgA (RV-IgA). Additionally, VP8∗ antibody responses were measured as part of an immunogenicity trial of a monovalent, oral, live-attenuated RV vaccine (Rotarix). RESULTS: Fewer children with acute RV gastroenteritis were seropositive for VP8∗-binding IgA or IgG antibodies at hospital admission compared with RV-IgA, suggesting that the absence of VP8∗-binding antibodies more accurately predicts susceptibility to RV gastroenteritis than RV-IgA in unvaccinated children. However, when present, these antibodies appeared insufficient to protect fully from disease and no threshold antibody level for protection was apparent. In vaccinated children, these antibodies were very poorly induced by Rotarix vaccine, suggesting that VP8∗-specific antibodies alone are not necessary for clinical protection following oral vaccination. CONCLUSIONS: This work suggests that VP8∗-binding antibodies may not be sufficient or necessary for protection from RV gastroenteritis following prior RV infection or oral vaccination; the role of VP8∗ antibodies induced by parenteral vaccination with non-replicating vaccines remains to be determined.

Molecular diagnostic methods improve the detection of Shigella, yet their ability to detect Shigella drug resistance on direct stool specimens is less clear. We tested 673 stool specimens from a Shigella treatment study in Bangladesh, including 154 culture-positive stool specimens and their paired Shigella isolates. We utilized a TaqMan array card that included quantitative PCR (qPCR) assays for 24 enteropathogens and 36 antimicrobial resistance (AMR) genes. Shigella was detected by culture in 23% of stool specimens (154/673), while qPCR detected Shigella at diarrhea-associated quantities in 49% (329/673; P < 0.05). qPCR for AMR genes on the Shigella isolates yielded >94% sensitivity and specificity compared with the phenotypic susceptibility results for azithromycin and ampicillin. The performance for trimethoprim-sulfamethoxazole susceptibility was less robust, and the assessment of ciprofloxacin was limited because most isolates were resistant. The detection of AMR genes in direct stool specimens generally yielded low specificities for predicting the resistance of the paired isolate, whereas the sensitivity and negative predictive values for predicting susceptibility were often higher. For example, the detection of ermB or mphA in stool yielded a specificity of 56% but a sensitivity of 91% and a negative predictive value of 91% versus the paired isolate's azithromycin resistance result. Patients who received azithromycin prior to presentation were universally culture negative (0/112); however, qPCR still detected Shigella at diarrhea-associated quantities in 34/112 (30%). In sum, molecular diagnostics on direct stool specimens greatly increase the diagnostic yield for Shigella, including in the setting of prior antibiotics. The molecular detection of drug resistance genes in direct stool specimens had low specificity for confirming resistance but could potentially "rule out" macrolide resistance.

BACKGROUND: Azithromycin is frequently used to treat shigellosis; however, clinical outcomes are uncertain. METHODS: We performed an observational cohort study in Bangladesh of patients with invasive diarrhea treated empirically with azithromycin. Susceptibility testing was performed by broth microdilution and disk diffusion post hoc on all Shigella isolates and clinical response was correlated with in vitro susceptibility. RESULTS: There were 149 Shigella culture-positive patients in the primary analysis. Infection with Shigella with decreased susceptibility to azithromycin was significantly associated with persistence of diarrhea at day 5 (31% vs 12%; relative risk [RR], 2.66; 95% confidence interval [CI], 1.34-5.28), culture positivity at day 5 or 6 (35% vs 5%; RR, 5.26; 95% CI, 1.84-14.85), and a higher rate of overnight hospitalization (58% vs 39%; RR, 1.49; 95% CI, 1.06-2.09). Shigella flexneri was more common than Shigella sonnei (58% vs 36%); however, S. sonnei constituted most of the isolates with decreased susceptibility to azithromycin (67%) and most of the multidrug-resistant strains (54%); thus, poor clinical outcomes were associated with S. sonnei. The current epidemiological cutoff for S. flexneri of ≥16 µg/mL to define decreased susceptibility to azithromycin was clinically predictive of poor outcome. Patients with S. sonnei and a low MIC (4 µg/mL) still had elevated rates of persistent diarrhea and culture positivity. CONCLUSIONS: This study documents worse clinical outcomes for S. flexneri with decreased susceptibility to azithromycin, as well as S. sonnei, and supports the utility of susceptibility testing and clinical breakpoints for azithromycin. S. sonnei is an emerging drug-resistant threat. CLINICAL TRIALS REGISTRATION: NCT03778125.

OBJECTIVE: The Onco E6™ Cervical Test, based on detection of the E6 oncoprotein of HPV 16 and 18 genotypes is evaluated as a screen for the early detection cervical neoplasia in resource-limited countries. METHODS: This prospective study from June 2018 to June 2019 evaluated 235 women aged 21-65 years, who came to Gynaecological Oncology Outpatient Department by VIA, cytology, E6 oncoprotein test and by colposcopy. Screen-positive women by any of the tests or women with suspicious findings were further evaluated by biopsy at colposcopy. The McNemar test was used to compare the performance of E6 oncoprotein test with other screening tests. RESULTS: The E6 oncoprotein positivity rate was 6.8% (n = 16) with 81.25% HPV 16 positive and 18.75% HPV 18 positive. Among VIA positive cases (n = 100), E6 oncoprotein was positive in 9% (p < .001). In histopathology confirmed chronic cervicitis, CIN I, CIN II, CIN III and invasive cervical cancer, E6 test was positive for 2.8%, 4.7%, 25%, 50% and 100% respectively. E6 oncoprotein test had the highest specificity and Positive Predictive Value (PPV; 97% and 75%) compared to VIA (42% and 18%), cytology (95% and 46%) and colposcopy (94% and 59%). Sensitivity of the E6 oncoprotein test for detection of CIN3+ was significantly higher than that of cytology (52% VS 25%) but lower than that of VIA (52% VS 74%). CONCLUSIONS: The HPV E6 oncoprotein test is highly specific and is an effective triage test to reduce colposcopy referrals for the large number of false positive test outcomes seen with VIA.

PURPOSE: The aim of the study was to evaluate the efficacy of hysterectomy in the control of pelvic disease in patients with post-irradiated residual cervical cancer. PATIENTS AND METHODS: Forty patients were treated at either National Institute of Cancer Research and Hospital (NICRH) or Delta Cancer Hospital in Dhaka, Bangladesh, with International Federation of Gynecology and Obstetrics stage IIB to IIIB disease with residual disease after the following: either concurrent chemoradiation with or without brachytherapy, induction chemotherapy and external-beam radiotherapy (EBRT) with or without brachytherapy, or only EBRT. Patients were treated by either radical hysterectomy or extrafascial hysterectomy. RESULTS: From 2009 to June 2013, 55 patients were evaluated for central residual disease on their presentations to NICRH or Delta Hospital. Patients with distant recurrences after primary radiation were excluded. Forty patients had invasive cancer on biopsy and underwent either radical hysterectomy or extrafascial hysterectomy. Surgery was performed 14 to 18 weeks after the initial treatment. Of the 29 women who underwent extrafascial hysterectomy, four (13.8%) developed recurrent disease, and one died; none of the 11 patients treated by radical hysterectomy experienced recurrences during the study period. Morbidity was increased in patients who underwent radical hysterectomy. Overall 90% of patients (36 of 40 patients) who underwent surgery had no evidence of disease at 5 years of follow-up. CONCLUSION: Surgery is a viable treatment option for patients with residual cervical cancer after radiation. Radical hysterectomy after radiation is more morbid but has better tumor control than extrafascial hysterectomy.

BACKGROUND: Iron deficiency anemia (IDA) is a significant problem worldwide particularly in women. The aim of the study was to evaluate the effectiveness and safety of intravenous ferric carboxymaltose (FCM) in comparison to iron sucrose (IS) in women with IDA. METHOD: Two hundred patients at Department of Obstetrics and Gynaecology, Sher-i-Kashmir Institute of Medical Sciences Medical College and Hospital, Jammu & Kashmir, India identified with IDA were enrolled for the study. Intravenous FCM and IS were both given as per the protocol. Change in the laboratory parameters such as hemoglobin (Hb), mean corpuscular value, and serum ferritin levels at two weeks and four weeks interval after the treatment was recorded. RESULT: A significant increase in the mean Hb was observed from 7.76 ± 0.709 to 13.25 ± 0.606 in patients treated with FCM and 7.64 ± 0.710 to 11.59 ± 0.733 g/dL (P < 0.001) in patients treated with IS after four weeks of therapy. The rise in mean corpuscular volume was from 66.82 ± 5.24 to 86.76 ± 3.765 and 68.05 ± 5.56 to 93.80 ± 3.80 and rise in serum ferritin levels were from 8.32 ± 1.787 to 38.94 ± 6.095 µg/L and 8.16 ± 1.540 to 27 ± 8.175 µg/L in patients treated with FCM and IS respectively after four weeks of therapy. No serious adverse effects were reported. CONCLUSION: Parenteral therapy is effective in IDA, but FCM elevates hemoglobin level and restored iron stores faster than IS with minimum adverse drug reactions.

The synthesis, spectroscopic, enzyme-inhibition, and free-radical-scavenging properties of a series of vanadium(IV) complexes, compounds 1-10, were investigated. These complexes exhibit a dimeric structure with hydrazide ligands coordinated in a bidentate fashion. All complexes are stable in the solid state, but exhibit varying degrees of stability in solution. In coordinating solvent such as DMSO, stepwise binding of two solvent molecules at the 6th positions trans to the V double bond O bond of the dimeric unit is observed. The dimeric compounds are converted to monomeric species in which both solvent molecules and the hydrazide ligands are coordinated to the V(IV) center. The free hydrazide ligands 11-20 were inactive against alpha-glucosidase, but the V(IV) complexes showed varying degrees of inhibition, depending on the type of ligand. The DPPH-radical-scavenging activities of 1-20 were determined, which indicated that steric and/or electronic effects responsible for changes in geometry play important roles in terms of antioxidant potential.

Vanadium plays an important role in biological systems and exhibits a variety of bioactivities. In an effort to uncover the chemistry and biochemistry of vanadium with nitrogen- and oxygen-containing ligands, we report herein the synthesis and spectroscopic characterization of vanadium(IV) complexes with hydrazide ligands. Substituents on these ligands exhibit systematic variations of electronic and steric factors. Elemental and spectral data indicate the presence of a dimeric unit with two vanadium(IV) ions coordinated with two hydrazide ligands along with two H(2)O molecules. The stability studies of these complexes over time in coordinating solvent, DMSO, indicates binding of the solvent molecules to give [V2O2L2(H2O)2(DMSO)2]2+ (L=hydrazide ligand) and then conversion of it to a monomeric intermediate species, [VOL(DMSO)3]1+. Hydrazide ligands are inactive against urease, whereas vanadium(IV) complexes of these ligands show significant inhibitory potential against this enzyme and are found to be non-competitive inhibitors. These complexes also show low phytotoxicity indicating their usefulness for soil ureases. Structure-activity relationship studies indicate that the steric and/or electronic effects that may change the geometry of the complexes play an important role in their inhibitory potential and phytotoxicity.
