RESUMO

OBJECTIVE: Malvidin is a natural, biologically active polyphenol found in several fruits. It exhibits several therapeutic benefits; however, limited studies are available on its effects on neurodegenerative clinical conditions, including Parkinson's disease. The study aimed to investigate the therapeutic properties of malvidin on rotenone-triggered Parkinson's disease in an animal model. MATERIALS AND METHODS: To determine the effects of malvidin, rotenone (1.5 mg/kg) was injected subcutaneously into Wistar rats for 21 days, followed by a dose of malvidin (200 and 100 mg/kg). Behavioral tests were performed on the experimental animals before sacrifice. On the 22nd day of the experiment, biochemical tests were performed, including superoxide dismutase (SOD), glutathione (GSH), malondialdehyde (MDA), and catalase (CAT). The activity of neurotransmitters and their metabolites, including acetylcholine (ACh), acetylcholinesterase (AChE), dopamine (DA), norepinephrine (NE), serotonin (5-HT), 3,4-dihydroxyphenylacetic acid (DOPAC), homovanillic acid (HVA), and 5-hydroxyindoleacetic acid (5-HIAA) along with neuroinflammatory markers including interleukin-6 (IL-6), interleukin-1ß (IL-1ß), tumor necrosis factor- α (TNF-α), and nuclear factor erythroid 2-related factor 2 (Nrf-2) were estimated. Moreover, the level of the apoptotic marker, caspase-3, was also estimated. In addition, molecular docking was performed. RESULTS: The administration of rotenone resulted in oxidative stress, cholinergic imbalances, dopaminergic alternations, and increased expression of inflammatory compounds. The docking analysis revealed that malvidin displayed a favorable binding affinity for AChE, showcasing a binding energy of -9.329 Kcal/mol. CONCLUSIONS: The investigation concludes that malvidin exhibits neuroprotective effects due to its curative effects against inflammation and oxidative stress. These findings suggest that malvidin possesses therapeutic potential against rotenone-triggered behavioral, oxidative, and inflammatory abnormalities in rodents.

RESUMO

This study was conducted to evaluate how sterubin affects rotenone-induced Parkinson's disease (PD) in rats. A total of 24 rats were distributed into 4 equal groups: normal saline control and rotenone control were administered saline or rotenone (ROT), respectively, orally; sterubin 10 received ROT + sterubin 10 mg/kg po; and sterubin alone was administered to the test group (10 mg/kg). Rats of the normal saline and sterubin alone groups received sunflower oil injection (sc) daily, 1 h after receiving the treatments cited above, while rats of the other groups received rotenone injection (0.5 mg/kg, sc). The treatment was continued over the course of 28 days daily. On the 29th day, catalepsy and akinesia were assessed. The rats were then euthanized, and the brain was extracted for estimation of endogenous antioxidants (MDA: malondialdehyde, GSH: reduced glutathione, CAT: catalase, SOD: superoxide dismutase), nitrative (nitrite) stress markers, neuroinflammatory cytokines, and neurotransmitter levels and their metabolites (3,4-dihydroxyphenylacetic acid (DOPAC), dopamine (DA), norepinephrine (NE), serotonin (5-HT), 5-hydroxyindoleacetic acid (5-HIAA), and homovanillic acid (HVA)). Akinesia and catatonia caused by ROT reduced the levels of endogenous antioxidants (GSH, CAT, and SOD), elevated the MDA level, and altered the levels of nitrites, neurotransmitters, and their metabolites. Sterubin restored the neurobehavioral deficits, oxidative stress, and metabolites of altered neurotransmitters caused by ROT. Results demonstrated the anti-Parkinson's activities of sterubin in ROT-treated rats.

RESUMO

OBJECTIVE: Recent research suggests that butin may also exert neuroprotective effects. However, its influence on cognitive performance and, specifically, its potential to mitigate scopolamine-induced memory impairment remains unexplored. The aim of the study is to investigate the effects of butin on the cognitive and behavioral performance of rats with scopolamine-induced memory impairment. MATERIALS AND METHODS: Scopolamine-injected memory-impediment model in rats was used to determine the efficacy of butin in higher and lower doses (10 and 20 mg/kg) for 14 days. Y-maze, along with Morris water, was used to assess the ability to recall spatial and working information. Biochemistry-related functions such as acetylcholinesterase, choline acetyltransferase, superoxide dismutase, glutathione transferase, malonaldehyde, catalase, nitric oxide, and neurotransmitters levels were estimated as indicators of free radical damage. Furthermore, we evaluated neuro-inflammatory responses by assessing tumor necrosis factor-alpha (TNF-α), interleukin 1 beta (IL-1ß), interleukin-6 (IL-6), brain-derived neurotrophic factor (BDNF) and caspase-3 immuno-reactive proteins. RESULTS: When assessed through behavioral paradigms, the butin-treated group enhanced the spatial and working memory of rodents. Scopolamine caused a substantial alteration in biochemical-related parameters, neuronal enzymatic, inflammation responses and apoptosis markers prominently restored by butin. CONCLUSIONS: This study concludes that butin protects scopolamine-injected rats from behavioral impairments and neuronal damage by reducing apoptosis and neuroinflammation.

RESUMO

BACKGROUND: Low back pain is a common health problem globally. Based on the duration of pain, it is classified as acute, subacute, or chronic low back pain. Different treatment strategies are available to reduce chronic low back pain. Virtual reality (VR) is a novel approach in back pain rehabilitation. OBJECTIVE: This study aimed to compare the effects of VR games on chronic low back pain. METHODS: This quasi-experimental study was conducted among 40 patients with chronic low back pain. The data were collected using a nonprobability, convenient sampling technique. Patients visiting the Department of Physiotherapy, Government Services Hospital, Lahore, Pakistan, were recruited and equally divided into 4 groups. Group A received the Reflex Ridge game; group B received the Body Ball game; group C combined the 2 games without back-strengthening exercises; and group D combined the 2 games with back-strengthening exercises. The participants received 8 treatment sessions, with 3 sessions/wk. The outcomes were pre- and posttest measurements of pain intensity, low back disability, and lumbar range of motion. The repeated measurement ANOVA was used for inter- and intragroup comparison, with significance at P≤.05. RESULTS: The study comprised a sample of 40 patients with low back pain; 12 (40%) were female and 28 (60%) were male, with a mean age of 37.85 (SD 12.15) years. The pre- and posttest mean pain scores were 7.60 (SD 1.84) and 4.20 (SD 1.62) in group A, 6.60 (SD 1.776) and 5.90 (SD 1.73) in group B, 6.90 (SD 1.73) and 5.40 (SD 1.07) in group C, and 7.10 (SD 1.53) and 3.60 (SD 0.97) in group D, respectively. The mean pain score differences of group D (combining the Reflex Ridge and Body Ball games with back-strengthening exercises) compared to groups A, B, and C were -.60 (P=.76), -2.30 (P<.001), and -1.80 (P=.03), respectively. Regarding the range of motion, the forward lumbar flexion mean differences of group D compared to groups A, B, and C were 3.80 (P=.21), 4.80 (P=.07), and 7.40 (P<.001), respectively. Similarly, the right lateral lumbar flexion mean differences of group D compared to groups A, B, and C were 2.80 (P=.04), 5.20 (P<.001), and 4.80 (P<.001), respectively. The left lateral lumbar flexion mean differences of group D compared to groups A, B, and C were 2.80 (P<.001), 4.80 (P=.02), and 2.20 (P<.001). respectively, showing significant pre- and posttreatment effects. CONCLUSIONS: VR exercises had statistically significant effects on improving pain, low back disability, and range of motion in all groups, but the combination of Reflex Ridge and Body Ball games with back-strengthening exercises had dominant effects compared to the other groups.

RESUMO

BACKGROUND: The activity of the amiloride-sensitive epithelial sodium channel (ENaC) in the tight epithelia of the lung is regulated by proteolytic activation and ubiquitination. Pathophysiology of lung diseases is directly related to changes in one or both of these mechanisms. METHODS: In this study, we investigated the impact of ubiquitination and cathepsin-mediated proteolytic activation mechanisms on the functional regulation of ENaC in lung cancer A549 cells using the patch-clamp technique. RESULTS: Our findings suggest that inhibiting the proteasome (polyubiquitination) with MG132 improves ENaC activity, whereas altering the pH of the lysosome (monoubiquitination inhibition) with NH4Cl has no effect on ENaC activity. In A549 cells, inhibition of cathepsin B (CSTB) decreased the ENaC current, open probabilities (NPo and Po), and the number of active channels. CONCLUSION: These findings delineate novel modes of ENaC degradation and proteolytic activation of functional channels in A549 cells. Our findings indicate that both proteolytic activation and ubiquitination of ENaC significantly affect channel function and add new insights into the endogenous ENaC processing which might help to further understand the pathophysiology of the lung disease.

RESUMO

BACKGROUND: While prostate multiparametric-magnetic resonance imaging (MP-MRI) has improved the diagnosis of clinically significant prostate cancer (CSPC), the complementary use of prostate-specific antigen (PSA) levels to risk-stratify for CSPC requires further study. The objective of this project was to determine if prostate MP-MRI and PSA can provide complementary insights into CSPC risk stratification. METHODS: In an IRB-approved study, pathologic outcomes from patients who underwent MR/US fusion-targeted prostate biopsy were stratified by various parameters including PSA, PSA density (PSAD), age, race, and PI-RADS v2 score. CSPC was defined as a Gleason score ≥7. Logistic regression was used to determine odds ratios (OR) with 95% confidence intervals (CI). P values were reported as two-sided with p < 0.05 considered statistically significant. ROC curves were generated for assessing the predictive value of tests and sensitivity + specificity optimization was performed to determine optimal testing cutoffs. RESULTS: A total of 327 patients with 709 lesions total were analyzed. PSAD and PI-RADS scores provided complementary predictive value for diagnosis of CSPC (AUC PSAD: 0.67, PI-RADS: 0.72, combined: 0.78, p < 0.001). When controlling for PI-RADS score, age, and race, multivariate analysis showed that PSAD was independently associated with CSPC (OR 1.03 per 0.01 PSAD increase, 95% CI 1.02-105, p < 0.001). The optimal cutoff of PSAD ≥ 0.1 ng/ml/cc shows that a high versus low PSAD was roughly equivalent to an increase in 1 in PI-RADS score for the presence of CSPC (4% of PI-RADS ≤3 PSAD low, 6% of PI-RADS 3 PSAD high vs. 5% of PI-RADS 4 PSAD low, 22% of PI-RADS 4 PSAD high vs. 29% of PI-RADS 5 PSAD low, 46% of PI-RADS 5 PSAD high were found to have CSPC). CONCLUSIONS: PSAD with a cutoff of 0.1 ng/ml/cc appears to be a useful marker that can stratify the risk of CSPC in a complementary manner to prostate MP-MRI.

RESUMO

Hematological and hematopoietic cells malignancies of the genes and hematopoietic cells are associated with the genetic mutation, often at the chromosomal level. The standard cytogenetic study is widely accepted as one of the main diagnostics and prognostic determinants in patients. Therefore, the current descriptive and cross sectional study sought to determine the cytogenetic analysis of frequent hematological malignancies in Pakistan. A total of 202 peripheral bone marrow or blood samples from patients with benign and malignant hematological malignancy were taken using a conventional G-banding technique. Among enrolled patients, the mean age was 21.5 years ± 23.4, and gender-wise distribution showed a marked predominance of the male 147 (73%) population compared to the female 55 (27%). Patients in the age group (2-10 years) had the highest frequency, 48 (24%), of hematological neoplasms, followed by age (11-20 years) with 40 (20%). Normal karyotypes (46, XX/46, XY) was found in 51% (n=103) patients. Furthermore, the frequency of complex karyotype was 30 (15%), while normal was seen in 171 (85%) patients. Pre-B Acute Lymphoblastic Leukemia (Pre-B ALL) was the most prevalent malignancy of 66 (33%), followed by Chronic Myelogenous Leukemia (CML) of 41 (20%) and Acute Lymphocytic Leukemia of 29 (14%). Translocation was the most prevalent 50 (25%), followed by hypotriploidy 14 (7%) and monosomy 8 (4%) on chromosome aberration analysis. In addition, t(9:22) translocation was found to be 20 (10%) in CML, with the majority in the age group (31-40 years). This study recommends that karyotyping should be tested frequently in hematological conditions because it may provide insight into the relative chromosomal changes associated with particular malignancies.

Entre os pacientes inscritos, a média de idade foi de 21,5 anos ± 23,4, e a distribuição por gênero mostrou uma marcada predominância da população masculina de 147 (73%) em comparação com a feminina de 55 (27%). Pacientes na faixa etária (2-10 anos) tiveram a maior frequência, 48 (24%), de neoplasias hematológicas, seguida da idade (11-20 anos) com 40 (20%). Cariótipos normais (46, XX / 46, XY) foram encontrados em 51% (n = 103) dos pacientes. Além disso, a frequência de cariótipo complexo foi de 30 (15%), enquanto normal foi observada em 171 (85%) pacientes. Leucemia linfoblástica aguda pré-B (LLA Pré-B) foi a doença maligna mais prevalente de 66 (33%), seguida por leucemia mieloide crônica (LMC) de 41 (20%) e leucemia linfocítica aguda de 29 (14%). A translocação foi o 50 mais prevalente (25%), seguido por hipotriploidia 14 (7%) e monossomia 8 (4%) na análise de aberração cromossômica. Além disso, a translocação t (9:22) encontrada foi de 20 (10%) na LMC, com a maioria na faixa etária (31-40 anos). Este estudo recomenda que o cariótipo deve ser testado com frequência em condições hematológicas porque pode fornecer informações sobre as alterações cromossômicas relativas associadas a doenças malignas específicas.

RESUMO

Ertapenem is a member of carbapenem antibiotics used for the treatment of moderate-to-severe intra-abdominal, urinary tract, acute pelvic, and post-surgical gynecologic infections. The antibacterial activity of ertapenem is mediated through binding to penicillin-binding proteins which results in inhibiting the cross-linking of the peptidoglycan layer of the bacterial cell wall. Therefore, ertapenem can be labeled with technetium-99m (99mTc), a gamma emitter radionuclide, for the diagnosis of deep-seated bacterial infections, such as urinary tract, intra-abdominal, osteomyelitis, and post-surgical gynecologic infections. The labeling procedure was carried out by varying the reaction conditions, such as the amount of the ligand and reducing agent, pH, reaction time and temperature, and radioactivity. At optimized reaction conditions more than 93% 99mTc-ertapenem radioconjugate was obtained. 99mTc-ertapenem was found 90% intact in saline medium up to 6 h, while 88% intact in human blood serum up to 3 h. Biodistribution study showed target-to-non-target ratios of 2.91 ± 0.19, 2.39 ± 0.31, and 1.23 ± 0.22 in S. aureus, E. coli, and turpentine oil-infected rat models, respectively. The SPECT scintigraphy showed high uptake of 99mTc-ertapenem in bacterial-infected abscesses, and low counts were recorded in normal and turpentine oil-inflamed tissues. In conclusion, 99mTc-ertapenem can be a potent infection-imaging agent, which can diagnosis deep-seated bacterial infections at early stage but need further pre-clinical evaluation in variety of infection models.

RESUMO

Introduction Peritonitis secondary to gastrointestinal perforation causes high morbidity and mortality rates in the emergency department with an immediate need for surgical intervention. Despite improved surgical management procedures, patients are still suffering from gastrointestinal leak causing peritonitis that demands surgical management by highly skilled surgeons in high-quality surgical units. Material and methods This paper presents one year of experience in the surgical treatment of gastrointestinal perforation-related peritonitis by surgeons in Lahore General Hospital, Lahore, Pakistan. Data was retrospectively collected from patient records and quantitatively analyzed. Involved patients developed peritonitis secondary to gastrointestinal perforation requiring surgical exploration and interventions in the emergency department between November 2020 and October 2021. Results One hundred and fifty-eight patients were involved; the mean age was 43.46 years. The number of males was 87 (55.06%). The patients mostly presented with generalized abdominal pain (57.6%). All the patients had perforation-related peritonitis, which was most prevalent in the ileum (62%). The most performed surgical intervention was loop ileostomy (36.71%). Compared to other published reports, the incidence rate of wound dehiscence in the hospital was relatively higher. Postoperatively, wound infection was low if the skin was left open (23.62%) compared to closed skin (38.7%). Patient outcomes were acceptable as the death rate was low (3.2%, 5/158). Conclusion Peritonitis caused by gastrointestinal perforation is associated with a high risk of morbidity that necessitates surgical exploration. Leaving skin wound open after the surgical intervention is recommended to decrease the incidence of wound infection and dehiscence.

RESUMO

BACKGROUND: Blunt aortic injury (BAI) and traumatic brain injury (TBI) are the leading causes of death after blunt trauma. The purposes of this study were to identify predictors of mortality for BAI and to examine the impact of procedural heparinization during thoracic endovascular aortic repair (TEVAR) on neurologic outcomes in patients with BAI/TBI. METHODS: Patients with BAI were identified over an 8 year period. Age, gender, severity of injury and shock, time to TEVAR, morbidity, and mortality were recorded and compared. Multivariable logistic regression (MLR) was performed to determine independent predictors of mortality. Youden's index determined optimal time to TEVAR. RESULTS: A total of 129 patients were identified. The majority (74%) were male with a median age and injury severity score (ISS) of 40 years and 29, respectively. Of these, 26 (20%) had a concomitant TBI. Patients with BAI/TBI had higher injury burden at presentation (ISS 37 vs. 29, P = 0.002; Glasgow Coma Scale [GCS] 6 vs. 15, P < 0.0001), underwent fewer TEVAR procedures (31 vs. 53%, P = 0.039), and suffered increased mortality (39 vs. 16%, P = 0.009). All TEVARs had procedural anticoagulation, including patients with TBI, without change in neurologic function. The optimal time to TEVAR was 14.8 hr. Mortality increased in TEVAR patients before 14.8 hr (8.7 vs. 0%, P = 0.210). MLR identified TEVAR as the only modifiable factor that reduced mortality (odds ratio 0.11; 95% confidence interval 0.03-0.45, P = 0.002). CONCLUSIONS: TEVAR use was identified as the only modifiable predictor of reduced mortality in patients with BAI. Delayed TEVAR with the use of procedural heparin provides a safe option regardless of TBI with improved survival and no difference in discharge neurologic function.

RESUMO

BACKGROUND: Somalia has been without an effective government since the collapse of the military regime in 1991. Years of conflict, disasters, and insecurity have all contributed to very low scores for most health indicators due to poor governance, protracted conflict, underdevelopment, economic decline, poverty, social and gender inequality, and environmental degradation. The three-decade long protracted conflict has led to widespread psychosocial trauma, social deprivation and substance abuse with devastating consequences on mental health. A WHO study showed Somalia has one of the highest rates of mental illness in the world. The main aim of this study is to assist policy makers in setting priorities for the design and delivery of interventions to promote mental health and psychosocial wellbeing in Somalia. METHODS: The study uses a systematic mapping technique (from January 1991 to May 2020) and data collected from public domain, to collect, collate, and present mental health data mainly from WHO's Global Health Observatory. Since there is no primary database for Somalia's public health research, the bibliographic databases used for mental health in this study included Medline, PubMed, CINAHL, PsycINFO, and Google Scholar. Data were extracted using techniques for web data mining for public health. RESULTS: Systematic mapping of mental health-related issues in Somalia showed that policy-related determinants and mental health services dominated (74.4%), followed by the disaster-related determinants and women's health consequences (39.3%). The ratio of the number of beds for mental health in general hospitals (per 100,000 population) in Somalia in 2017 is 0.5 compared to the Eastern Mediterranean region (EMR) at 6.4 and globally at 24. One of the biggest casualties of the civil war was loss of essential human resources in healthcare as most either fled the country or were part of the victims of the war. CONCLUSIONS: The vast scale of the mental health problems in Somalia and the priority setting guidelines for interventions to address the issues outlined in this paper, prompt a dire need that the Somali government and its national/international partners should prioritize and emphasize the need to invest in the prevention and the treatment of mental illness across the country.

RESUMO

High resistance to antimicrobials is associated with biofilm formation responsible for infectious microbes to withstand severe conditions. Therefore, new alternatives are necessary as biofilm inhibitors to control infections. In this study, the antimicrobial and antibiofilm activities of Fagonia indica extracts were evaluated against MDR clinical isolates. The extract exhibited its antibiofilm effect by altering adherence and disintegration of bacterial cell wall. Fagonia indica has antibacterial effect as minimum inhibitory concentration (MIC) values ranging from 125 to 500 µg mL-1 and minimum bactericidal concentration (MBC) value was 500-3000 µg mL-¹ against multidrug resistant (MDR) clinical isolates. The extract exhibited its antibiofilm effect by altering adherence and disintegration of bacterial cell wall. Fagonia indica had antibacterial effect as minimum inhibitory concentration (MIC) values ranging from 125 to 500 µg mL-¹ and minimum bactericidal concentration (MBC) value was 500-3000 µg mL-¹ against MDR isolates. The maximum inhibitory effects of Fagonia indica chloroform extract on biofilm formation was observed on Staphylococcus aureus (71.84%) followed by Klebsiella pneumoniae (70.83%) after 48 hrs showing that inhibition is also time dependent. Our results about bacterial cell protein leakage indicated that MDR isolates treated with chloroform extract of Fagonia indica showed maximum protein leakage of K. pneumoniae (59.14 µg mL-¹) followed by S. aureus (56.7 µg mL-1). Cell attachment assays indicated that chloroform extract resulted in a 43.5-53.5% inhibition of cell adherence to a polystyrene surface. Our results revealed that extracts of Fagonia indica significantly inhibited biofilm formation among MDR clinical isolates, therefore, could be applied as antimicrobial agents and cost effective biofilm inhibitor against these MDR isolates.

RESUMO

Hematological and hematopoietic cells malignancies of the genes and hematopoietic cells are associated with the genetic mutation, often at the chromosomal level. The standard cytogenetic study is widely accepted as one of the main diagnostics and prognostic determinants in patients. Therefore, the current descriptive and cross-sectional study sought to determine the cytogenetic analysis of frequent hematological malignancies in Pakistan. A total of 202 peripheral bone marrow or blood samples from patients with benign and malignant hematological malignancy were taken using a conventional G-banding technique. Among enrolled patients, the mean age was 21.5 years ± 23.4, and gender-wise distribution showed a marked predominance of the male 147 (73%) population compared to the female 55 (27%). Patients in the age group (2-10 years) had the highest frequency, 48 (24%), of hematological neoplasms, followed by age (11-20 years) with 40 (20%). Normal karyotypes (46, XX/46, XY) was found in 51% (n=103) patients. Furthermore, the frequency of complex karyotype was 30 (15%), while normal was seen in 171 (85%) patients. Pre-B Acute Lymphoblastic Leukemia (Pre-B ALL) was the most prevalent malignancy of 66 (33%), followed by Chronic Myelogenous Leukemia (CML) of 41 (20%) and Acute Lymphocytic Leukemia of 29 (14%). Translocation was the most prevalent 50 (25%), followed by hypotriploidy 14 (7%) and monosomy 8 (4%) on chromosome aberration analysis. In addition, t(9:22) translocation was found to be 20 (10%) in CML, with the majority in the age group (31-40 years). This study recommends that karyotyping should be tested frequently in hematological conditions because it may provide insight into the relative chromosomal changes associated with particular malignancies.

RESUMO

Cystic echinococcosis (CE) is a zoonotic disease caused by the larval stage of Echinococcus granulosus tapeworms. These parasites have a worldwide geographic distribution and pose a serious threat to livestock industry as well as human health in the endemic areas. CE is widely distributed in Pakistan. However, very few reports are available related to the regional transmission of E. granulosus. A retrospective analysis was conducted of surgically confirmed CE patients who were treated at Shoukat Khanum Memorial Cancer Hospital and Research Centre in Lahore, Punjab Province, Pakistan from 2007 - 2018. In total, 536 CE patients were evaluated during the study period. Cases originated from the provinces of Khyber Pakhtunkhwa (n=336), Punjab (n=147), Baluchistan (n=18), Sindh (n=3), Islamabad (n=2), Gilgit Baltistan (n=1), and Azad Jammu and Kashmir (n=1). An additional 28 cases were from Afghanistan. The highest number of CE cases was reported in 2013 (n=90). Females made up a larger proportion of cases (n=310; 57.8 %) than males (n=226; 42.2 %). Most patients were members of the Pashtun (n=197; 36.7 %), Hindku (n=142; 26.5 %), and Punjabi (n=118; 22.0 %) ethnic groups. The largest number of cysts was obtained from the liver (137/536; 25.6 %). This study showed that CE is likely present throughout Pakistan. In order to control the disease, a comprehensive control program and regional surveillance are needed.
