RESUMO

Tyrosine is one of the essential metabolites present in the human body for nutritional maintenance and normal physiological functioning. Its concentration in the body is crucial in predicting various hereditary, emotional, and physiological disorders. Therefore, quantitative monitoring of tyrosine in clinical samples is indispensable. We state the use of carbon nanocoils/manganese tetraphenylporphyrin convened glassy carbon electrode (CNC/MnTPP/GC) for the streamlined electrochemical sensing of tyrosine. Cutting-edge analytical techniques were employed to perform a comprehensive physicochemical analysis of the synthesized materials. To investigate the electrochemical properties, various techniques such as cyclic voltammetry (CV), differential pulse voltammetry (DPV), electrochemical impedance spectroscopy, and chronocoulometry were employed. CNC/MnTPP/GC displayed an optimal response at pH 5 and exhibited remarkable linearity within the concentration range of 0.05 to 100 µM for tyrosine. Using DPV, it demonstrated a low limit of detection (21 nM ± 1.17) and a sensitivity of 0.12 µA µM-1 cm-2. CNC/MnTPP/GC displayed excellent performance in terms of repeatability, reproducibility, and stability for up to 30 days, making it suitable for real-time analysis, particularly in the analysis of tyrosine in blood serum. Notably, CNC/MnTPP/GC showcased a superior detection limit compared to previously reported methods.

RESUMO

INTRODUCTION: Cutaneous leishmaniasis (CL) is one of the neglected tropical diseases that affects impoverished communities throughout the world. In Pakistan CL is an endemic disease. AIMS AND OBJECTIVES: This study aimed to determine the incidence of CL infection in the Baluchistan province of Pakistan from January 2020 to March 2022 during the COVID-19 pandemic. METHODOLOGY: A total of 1047 clinically suspected cases of CL from Bolan Medical College Hospital, Quetta, were followed up in the study. The data regarding the epidemiological characterstics, pathological information, and treatment of patients was collected. RESULTS: Out of 1047 probable cases of CL, 594 (56.73%) cases were found to be positive for CL. Females had the highest infection rate, with the majority of reported cases being in the 0-9-year age group. Most CL cases were reported in April in the year 2020, with a few cases reported in June. But in the year 2021, the highest number of cases were reported in December. The number of overall cases has gradually increased in the year 2022, most likely because of the reduction in COVID-19 pandemic restrictions. The p value for the positive as compared to suspected cases in the years 2020, 2021, and 2022 was calculated as 0.8925, 0.8763, and 0.8535 respectively. CONCLUSIONS: Further epidemiological studies and health education campaigns are recommended to increase public awareness. It is strongly advised that local, provincial, and national health authorities establish and maintain effective leishmaniasis surveillance systems to promptly identify disease outbreaks and implement timely control measures.

RESUMO

Cancer is a long-standing disease, and the use of anticancer drugs can cause many different harmful side effects. Therefore, the quantitative analysis of anticancer drugs is crucial. Among all the analytical techniques that have been utilized for the detection of doxorubicin, electrochemical sensors have drawn exceptional consideration because they are simple, affordable, and highly sensitive. Manganese tetraphenylporphyrin decorated reduced graphene oxide (Mn-TPP/RGO), tetraphenylporphyrin decorated reduced graphene oxide (TPP/RGO), and reduced graphene oxide (RGO) nanostructure based glassy carbon electrodes (GCEs) were fabricated for the detection of doxorubicin (DOX). The synthesized materials were characterized by FTIR, scanning electron microscopy (SEM), ultraviolet-visible spectroscopy (UV/vis), energy dispersive X-ray spectroscopy (EDS), and X-ray diffraction (XRD). Doxorubicin detection was performed using differential pulse voltammetry (DPV), electrochemical impedance spectroscopy (EIS), and cyclic voltammetry (CV). Among the prepared electrodes, Mn-TPP/RGO modified GCE gave an optimum peak current at pH 3. The Mn-TPP/RGO modified electrode showed significant linear response range (0.1-0.6 mM); effective sensitivity (112.09 µA mM-1 cm-2); low detection limit (63.5 µM); and excellent stability, selectivity, repeatability, and reproducibility toward doxorubicin. With differential pulse voltammetry, LoD and sensitivity were 27 µM and 0.174 µA µM-1 cm-2, respectively. Real sample analysis was also performed in human serum, and it depicted reasonable recovery results for spiked doxorubicin.

RESUMO

Group B Streptococcus (GBS), also known as Streptococcus agalactiae, is a gram-negative, beta-hemolytic facultative anaerobe that causes neonatal pneumonia and sepsis. The neoplastic epithelial cells in adults, especially those of squamous origin, can show special adhesive properties toward GBS, which tends to reside within these tumors. There are some animal and human studies proving this association. Here, we present a 64-year-old female patient who had lung carcinoma of mixed adeno and squamous origin found to have persistent GBS every time the bronchoscopy was done for tumor ablation or cryotherapy. Subsequently, after starting her on chemo-radiotherapy, she also presented with multiple episodes of pneumonia caused by GBS and Pseudomonas aeruginosa. Moreover, many animal studies have shown the anti-tumor properties of GBS toxin that can prevent its metastasis and stop vascular growth surrounding the tumor. This property of GBS toxin can prove a blessing in disguise.

RESUMO

This study aimed to prepare three imine derivatives (1, 2, and 3) via a condensation reaction of phenyl hydrazine, 2-hydrazino pyridine, and 4-methoxy aniline with 4-formyl pyridine. Electron impact mass spectrometry (EIMS), proton nuclear magnetic resonance (1H-NMR), ultraviolet-visible (UV-Vis) and Fourier transform infrared (FTIR) spectroscopy were utilized for the characterization. The chemosensing properties of [4((2-phenyl hydrazono)methyl) pyridine] (1), [2-(2-(pyridin-4-ylmethylene)hydrazinyl) pyridine] (2), and [4-methoxy-N-yl methylene) aniline] (3) imino bases have been explored for the first time in aqueous media. The photophysical properties of chemosensors (1, 2, and 3) were examined by various cations (Na+, NH4+, Ba+2, Ni+2, Ca+2, Hg+2, Cu+2, Mg+2, Mn+2, and Pd+2). The chemosensor (1) showed very selective binding capability with copper ions at low concentrations (20 µM) without the influence of any other mentioned ions. The maximum complexation was noted with Cu+2 and 1 at pH between 7 to 7.5. The stoichiometry binding ratio between chemosensor (1) and Cu+2 was determined by Job's plot and it was found to be 1:2. The current study explored the use of these Schiff bases for the first time as heterocyclic chemosensors. DPPH radical scavenging, urease enzyme inhibition activities, molecular docking simulation, and density functional theory (DFT) analysis of compounds 1, 2, and 3 were also conducted.

RESUMO

Background: Virtual reality (VR) based meditation has been shown to help increase relaxation and decrease anxiety and depression in younger adults. However, this has not been studied in Randomized Controlled Trials (RCT) in the older adult population. The aim of this RCT is to assess the feasibility and acceptability of a VR-guided meditation intervention for community-dwelling older adults and its effect on stress and mental health. Methods: We will recruit 30 participants aged ≥ 60 years, whose perceived stress score (PSS) is > 14 (moderate stress), and randomize them 1:1 to the intervention or control waitlist group. The intervention will involve exposure to eight 15-min VR-guided meditation sessions distributed twice weekly for 4-weeks. Two modalities will be offered: in-home and at the hospital. Data analysis: Baseline and post-intervention assessments will evaluate perceived stress, anxiety, depression, sleep quality, quality of life, and mindfulness skills. Analyses will employ mixed methods repeated ANOVA tests. Qualitative analyses through semi-structured interviews and participant observation will be used to assess participants' experiences. Study outcomes include: (A) feasibility and acceptability compared to a waitlist control (B) stress, using the Perceived Stress Scale (PSS); (C) anxiety, and depression, using the Generalized Anxiety Disorder-7 (GAD-7) and Patient Health Questionnaire-9 (PHQ-9); (D) insomnia, quality of life and mindfulness skills, using the Athens Insomnia Scale (AIS), Quality of Life Questionnaire (EQ-5D-5L) and Five Facets Mindfulness Questionnaire Short Forms (FFMQ-SF), respectively. We will also measure immersive tendencies, sickness and sense of presence using the Simulator Sickness Questionnaire (SSQ) and the Presence Questionnaire (PQ). Discussion: Virtual reality-guided meditation could be an acceptable, feasible, safe, and cost-effective novel alternative health intervention for improving older adults' mental health.Clinical trial registration: NCT05315609 at https://clinicaltrials.gov.

RESUMO

Multidrug-resistant (MDR) gram-negative bacteria have been causing havoc for the healthcare system because of the rarity of the treatment options available. Stenotrophomonas maltophilia is a non-fermenting gram-negative bacterium that causes different infections, particularly respiratory tract infections. It displays resistance to many antibiotics (e.g., carbapenems, fluoroquinolones, and trimethoprim-sulfamethoxazole). Cefiderocol is a novel antibiotic which still in the preclinical stages of Food and Drug Administration (FDA) approval for S. maltophilia. We present the case of a 76-year-old male with end-stage renal disease (ESRD), intubated for acute hypoxemic respiratory failure due to volume overload and worsening oxygenation, who subsequently developed ventilator-associated pneumonia, found to be due to MDR Stenotrophomonas maltophilia. The patient ultimately showed clinical improvement with a 7-day course with a renally adjusted dose of cefiderocol. This shows that cefiderocol can prove to be a potential treatment option against serious infections caused by difficult-to-treat S. maltophilia.

RESUMO

Cocaine abuse has an overwhelming effect on the healthcare system due to its multiple complications. Cardiovascular complications carry the highest burden. Common cardiovascular manifestations of cocaine are related to its adrenergic effects due to the inhibition of dopamine and norepinephrine uptake at the postsynaptic terminal. However, chronic abuse can lead to desensitization of adrenergic receptors, which can lead to bradycardia. Sinus bradycardia can be one of the markers of chronic cocaine abuse, as exemplified in this case report. Therefore clinicians should be aware of this association.

RESUMO

Abdominal tuberculosis (TB) is a common form of extrapulmonary TB (EXPTB). It is being reported increasingly, especially in high-burden regions of the world. We present a case of a 37-year-old male who presented to the emergency department with clinical features suggestive of bowel obstruction. On clinical examination, the patient exhibited generalized tenderness in the abdomen. A subsequent CT scan revealed features consistent with small bowel obstruction. The patient underwent a diagnostic laparoscopy, which was converted to an exploratory laparotomy due to intraoperative findings of adhesions. Notably, there were extensive peritoneal deposits and adhesions between bowel loops. Peritoneal biopsies were obtained and subjected to the acid-fast bacillus (AFB) smear and culture, which demonstrated the growth of the Mycobacterium tuberculosis complex. As a result, the patient was initiated on antituberculous therapy.

RESUMO

Moxifloxacin and gemifloxacin are the two newer broad-spectrum 8-methoxy-quinolone derivatives that are used to treat various bacterial infections in cardiac patients. In this research study, we assessed the impact of moxifloxacin and gemifloxacin on the QT intervals of electrocardiograms in normal adult doses and draw a comparison, in a controlled environment, on healthy volunteers. Additionally, the effect of both test drugs on the QRS complex was checked. Sixty healthy volunteers were randomly assigned to two groups via R-software, and each respectively received moxifloxacin and gemifloxacin for five days. The research ethics committee approved the research, and it was registered for clinical trial under NCT04692623. The participants' electrocardiograms were obtained before the start of the dose (baseline) and on the fifth day. Significant prolongation of QT interval was noted in moxifloxacin (p < 0.0001) as compared to gemifloxacin treated groups. There were no cases of QTc prolongation over the usual limits (450-470 ms) in the gemifloxacin-treated group, however, QTc prolongations at the rate of 30 and 60 ms from the baseline were noted, interpreted as per the EMEA guidelines. These findings indicate that moxifloxacin caused significant (p < 0.0001) QT interval prolongation (QTIP) as compared to gemifloxacin. In contrast to the previously reported literature, the prominent effect of moxifloxacin on the widening of the QRS-complex was noted with no such effect on QRS-widening in the gemifloxacin-treated group. It is concluded that both drugs have the potential for considerable QT interval prolongation (QTIP) effects, which is one of the risk factors for developing torsade de pointes (TdPs) in cardiac patients. Thus, clinicians should exercise caution when prescribing moxifloxacin and gemifloxacin to cardiac patients and should consider alternate treatment options.

RESUMO

Pakistani's men with Premature ejaculation (PE) hardly prefer to go for treatment due to cultural barriers (men dominating society). This research objective is the gives knowledge about the effective treatment of premature ejaculation, how it can be effectively treated with the help of different techniques. Premature ejaculation (PE) is happened when a man has an orgasm and ejaculated earlier at the time of intercourse then he or his spouse would like. PE is a men sexual dysfunction that creates a significant anguish for men, partner and their relationships'. Premature ejaculation is not only one illness; it contains 4 subtypes with a unique psychological concern and problems (longtime, acquired, organic and subjective). PE men and couples are treated psychologically for sexual ability but also for self-esteem, performance anxiety and interpersonal disputes. Psychotherapy outcomes alone are hard to compare and to appreciate due to insufficient methodology (lacking control groups, limited sample sizes, poor results and insufficient monitoring). Rare researches, however, which overcome these methodological barriers, indicate that psychological intervention provides a promising treatment choice for men and partners. A detail literature review was done via an electronic database, "Cochrane library databases", "PsychInfo", and "PubMed" from June to July 2021. The most effective procedure for lifetime and acquired PE is pharmaco- and psychotherapy combination. Men and partners develop sexual abilities and resolve the intra-psychological, interpersonal and cognitive problems that trigger and sustain dysfunction.

RESUMO

Background: A pressing challenge during the COVID-19 pandemic and beyond is to provide accessible and scalable mental health support to isolated older adults in the community. The Telehealth Intervention Program for Older Adults (TIP-OA) is a large-scale, volunteer-based, friendly telephone support program designed to address this unmet need. Methods: A prospective cohort study of 112 TIP-OA participants aged ≥60 years old was conducted in Quebec, Canada (October 2020-June 2021). The intervention consisted of weekly friendly phone calls from trained volunteers. The primary outcome measures included changes in scores of stress, depression, anxiety, and fear surrounding COVID-19, assessed at baseline, 4 and 8-weeks. Additional subgroup analyses were performed with participants with higher baseline scores. Results: The subgroup of participants with higher baseline depression scores (PHQ9 ≥10) had significant improvements in depression scores over the 8-week period measured [mean change score = -2.27 (±4.76), 95%CI (-3.719, -0.827), p = 0.003]. Similarly, participants with higher baseline anxiety scores (GAD7 ≥10) had an improvement over the same period, which, approached significance (p = 0.06). Moreover, despite peaks in the pandemic and related stressors, our study found no significant (p ≥ 0.09) increase in stress, depression, anxiety or fear of COVID-19 scores. Discussion: This scalable, volunteer-based, friendly telephone intervention program was associated with decreased scores of depression and anxiety in older adults who reported higher scores at baseline (PHQ 9 ≥10 and GAD7 ≥10).

RESUMO

Introduction: Diabetes and thyroid disorders are the two most common disorders amongst endocrine diseases. Uncontrolled diabetes mellitus (DM) may disturb thyroid metabolism by disturbing the levels of thyroid hormones in the plasma. This study was undertaken to determine the prevalence and thyroid dysfunction in type 2 diabetic population presenting in a public sector tertiary care teaching hospital. Materials and Methods: This descriptive cross-sectional study was conducted in Civil Hospital Karachi (CHK) in the department of medicine from October 01, 2018, to March 31, 2019. The study population consisted of 317 patients diagnosed with DM type 2 based on American Diabetes Association (ADA) criteria. Patients with fasting blood sugar ≥ 126 mg/dL, or HbA1c >6.5 (%), and 2 h postprandial blood glucose levels >200 mg/dL were included. After a minimum of 8 h of fasting, plasma samples of patients were collected and sent for fasting blood glucose, HbA1c, FT3, FT4, and thyroid-stimulating hormone (TSH). Descriptive statistics were calculated. Post-stratification Chi-squared test was applied, and a P value of ≤ 0.05 was considered significant. Results: Among all enrolled DM type 2 patients, 207 (65.3%) were male with a mean age of 46.54 ± 8.72 years. Mean fasting blood sugar (FBS), random blood sugar (RBS), and HbA1c were 212.76 ± 26.91 (mg/dL), 328.89 ± 52.89 (mg/dL), and 9.43 ± 2.47 (%), respectively. The mean duration of DM was 7.81 ± 3.15 years. Mean FT3, FT4, and TSH were 113.13 ± 44.40 (ng/dL), 7.63 ± 3.11 (mg/dL) and 2.64 ± 2.57 (mIU/mL), respectively. In the present study, 55 (17.4%) patients had subclinical hypothyroidism, 27 (8.5%) had hypothyroidism, 19 (6.0%) had hyperthyroidism, and 16 (5.0%) had subclinical hyperthyroidism. Significant association of thyroid dysfunction was established with age group, female gender, and family history of thyroid dysfunction (P =< 0.001). Conclusion: The prevalence of thyroid dysfunction is higher among patients with type 2 diabetes mellitus (T2DM), in which hypothyroidism was the most common dysfunction with more prevalence among female patients.

RESUMO

In this work, Dodonaea oil was studied as a potential biodiesel source. Dodonaea (Dodonaea viscosa Jacq.) is an evergreen shrubby plant that thrives in tropical and subtropical conditions. The plant produces high-grade biodiesel in terms of both quantity and quality despite its naturally high fat content. In the transesterification followed by esterification reaction, varied ratios of oil to methanol, constant temperature (60°), reaction duration (1 h), and different catalyst concentrations (0.25-0.75% (w/w) were utilized. A maximum biodiesel yield of 90% was achieved. For fuel characteristic analysis, the prepared biodiesel was specified and compared to ASTM criteria. The chemical composition was verified using analytical techniques such as FT-IR and NMR spectroscopy. As a result of the foregoing, Dodonaea is considered a possible bioenergy source, particularly in the transport sector.

RESUMO

Fluoroquinolones (FQs) have been reported to cause dysglycemia in both diabetic and non-diabetic patients. However, diabetic patients are usually on polypharmacy, so we cannot attribute the dysglycemia specifically to FQs. To answer the question as to whether Moxifloxacin and Gemifloxacin influence blood glucose levels and serum insulin levels or otherwise, rabbits were used as experimental animals in an in vivo model followed by a phase I randomized clinical trial in euglycemic healthy volunteers. The effects on the serum insulin and blood glucose levels in the Moxifloxacin and Gemifloxacin treated groups were, respectively, determined on the fifth day in both the in-vivo rabbits model and in the test subjects of the phase I clinical trial. The effects of these drugs were also checked on the histomorphology of the pancreas in the rabbits. The findings of our study suggest that Moxifloxacin and Gemifloxacin significantly (p < 0.05) reduced the blood glucose levels via a subsequent significant shift in the serum insulin levels both in the in vivo animal model and in the test subjects of the phase I clinical trial. No prominent effects on the beta cells histomorphology were noted in this study. Moxifloxacin showed a more significant effect than Gemifloxacin. The insulinotropic effect was comparable to the effect of Glibenclamide. It is concluded that Moxifloxacin and Gemifloxacin have a significant blood glucose lowering effect mediated through insulinotropic action. (Clinical Trials.gov identifier: NCT04692623).

RESUMO

Cu-doped TiO2 (0.1, 0.25, and 0.5% Cu-TiO2) photocatalyst was prepared by sol-gel method and was characterized by powder XRD, FTIR, TEM, SEM, EDX, UV-vis diffuse reflectance (DRS), photoluminescence (PL), and Raman spectroscopy. The XRD spectrum shows tetragonal anatase phase. TEM analysis indicate that the nanoparticles were spherical with sizes 12-13 nm. The degradation of NB was studied, and an optimal degradation time of 180 min led to 98.6% NB abatement of NB = 0.05 mM, pH = 4, and catalyst loading = 50 mg/100 mL, under visible light. The degradation of NB follows the pseudo-first-order kinetics. The reusability studies indicated the excellent stability of 0.25% Cu-TiO2.

RESUMO

Objectives: To compare the effects of exergaming and vestibular training on gaze stability, balance and gait performance of older adults. METHODS: The single-blind randomised controlled trial was conducted from August to October 2020 at the Doctor Raza Clinic, Swabi, Pakistan, and comprised individuals of both genders aged 60-75 years. The subjects were randomised into two groups using the sealed envelope method. Group 1 received exergaming, while group 2 received vestibular training 3 days a week for 6 weeks. The outcomes measures were dynamic gait index, time up and go test and non-instrumented dynamic visual acuity test. Data was analysed using SPSS 21. RESULTS: Of the 24 subjects, 12(50%) were in each of the two groups. Overall, there were 16(66%) males and 8(33%) females with a mean age of 66.3±4.36 years. Intra-group improvement was significant compared to the baseline (p<0.05) in both the differences, but inter-group differences across all parameters were non-significant (p>0.05). CONCLUSIONS: Both exergaming and vestibular training has similar effects on gaze stability, balance, and gait performance among the older adults. Clinical Trials.gov Identifier: NCT04414462.

RESUMO

Nanotheranostics is an emerging frontier of personalized medicine research particularly for cancer, which is the second leading cause of death. Supramolecular aspects in theranostics are quite allured to achieve more regulation and controlled features. Supramolecular nanotheranostics architecture is focused on engineering of modular supramolecular assemblies benefitting from their mutable and stimuli-responsive properties which confer an ultimate potential for the fabrication of unified innovative nanomedicines with controlled features. Amalgamation of supramolecular approaches to nano-based features further equip the potential of designing novel approaches to overcome limitations seen by the conventional theranostic strategies, for curing even the lethal diseases and endowing personalized therapeutics with optimistic prognosis, endorsing their clinical translation. Among many potential nanocarriers for theranostics, lipid nanoparticles (LNPs) have shown various promising advances in theranostics and their formulation can be tailored for several applications. Despite the great advancement in cancer nanotheranostics, there are still many challenges that need to be highlighted to fill the literature gap. For this purpose, herein, we have presented a systematic overview on the subject and proposed LNPs as the potential material to manage cancer via non-invasive approaches by highlighting the use of supramolecular approaches to make them robust for cancer theranostics. We have concluded the review by entailing the future perspectives of lipid nanotheranostics towards clinical translation.
