RESUMEN
Hemoptysis due to saphenous venous graft (SVG) aneurysm is an extremely rare condition and published literature has described the role of conservative management, surgical resection, and covered stent. Here, we report a successful placement of a covered stent for SVG aneurysm in a 56-year-old male who presented with hemoptysis. He was a known diabetic and had undergone a coronary artery bypass grafting 5 years ago. Computed tomography (CT) chest and fiberoptic bronchoscopy performed in another local hospital had revealed blood in the left lingula with spillover into the left lung parenchyma. Hence, he had received empirical anti-tuberculosis medication for 2 months without any improvement. He was referred to our hospital for further management of hemoptysis. Multidetector CT (MDCT) angiography of the chest covering coronaries performed at our hospital revealed SVG aneurysm that was managed with covered stent placement.

Lung transplantation using RNA+ hepatitis C (HCV+) donors to seronegative recipients is not currently performed due to the very high risk of transmission. Previous reports have shown poor survival when this practice was applied. The emergence of new direct-acting antiviral drugs (DAA) suggests a high chance of sustained virologic response in immunocompetent patients. We report here successful transplantation of lungs from HCV+ donor to HCV- recipient. The recipient was an HCV- patient with chronic lung allograft dysfunction. Viral transmission occurred early posttransplant but excellent clinical outcomes were observed including elimination of HCV after 12 weeks of treatment using DAAs.

BACKGROUND: Vitis vinifera 'muscat hamburg' (Vitaceae) is a blue-black grape variety commonly found in Pakistan. It has been consumed and used in traditional medicine for centuries. Compared to other grapes, M. hamburg records one of the greatest amount of polyphenols and displays potent antioxidant activities, which make it a great candidate for its exploitation in the development of stable cream emulsions destined to improve the skin appearance. OBJECTIVE: Evaluate the effects of stable water-in-oil (W/O) emulsion containing 2% M. hamburg grape seed extract ('formulation') on human cheek skin in comparison with the placebo ('base'). METHODS: An occlusive patch test, containing either the formulation or the base, was topically tested for 8 weeks during a winter period in young adult and healthy Pakistani male volunteers. The subjects were instructed to use twice a day the base and the formulation on their right and left cheek skin, respectively. Non-invasive measurements on these skin areas were carried out every week to assess any effects produced on melanin, elasticity and sebum. Skin compatibility assay (Burchard test) was used to report any potential skin reactivity. ANOVA, paired sample t-test and LSD test were applied to determine the statistical data significance. RESULTS: Significant differences (P ≤ 0.05) were found between the placebo and the formulation in terms of their respective skin effects elicited on melanin, elasticity and sebum content. Nevertheless, placebo and formulation exerted similar effects on skin erythema and moisture contents. Importantly, no skin hypersensitivity cases were reported during the whole course of the study. CONCLUSION: The developed grape-based cream could be efficiently and safely applied to improve a number of skin conditions (e.g. hyper-pigmentation, premature ageing, acne).

Serological diagnosis of cystic echinococcosis (CE) is usually made by detecting specific antibodies in serum samples. However, collection of blood samples is difficult and may be hazardous and unsafe. Thus, it is important to assess alternative simple methods of sampling body fluids that give similar results. Saliva and urine have been suggested as possible alternatives to detect specific antibodies for the diagnosis of various diseases. To the best of our knowledge, there has been no previously published study regarding the detection of CE-specific immunoglobulin (Ig) G subclass antibodies (IgG1-4) in urine. Therefore, the present study was designed to assess the value of hydatid-specific antibodies of IgG, IgM, IgE and IgG subclass in urine and serum samples for the diagnosis of CE. Serum and urine samples of 41 surgically confirmed patients of CE, 40 patients with other diseases and 16 healthy subjects were included in the study. CE-specific total IgG, IgE and IgG4 in sera and total IgG, IgG4 and IgG1 in the urine of CE patients were the most important specific antibodies for the diagnosis of CE. However, total IgG usually persists for an extended period and has a very high cross-reactivity. The diagnostic sensitivity of hydatid-specific IgM in serum and urine samples was very low and therefore cannot be used as a diagnostic marker. There was no significant difference between IgG1 and IgG4 in serum and urine and both showed the best correlation for the diagnosis of CE. These considerations suggest that detection of antibodies in urine could provide a new approach in the diagnosis of CE.

A key barrier to epidemiological research on child behaviour problems in developing countries is the lack of culturally relevant, internationally recognized psychometric instruments. This paper proposes a model for the qualitative adaptation of psychometric instruments in developing-country settings and presents a case study of the adaptation of 3 internationally recognized instruments in Pakistan: the Child Behavior Checklist, the Youth Self-Report and the Teacher's Report Form. This model encompassed a systematic procedure with 6 distinct phases to minimize bias and ensure equivalence with the original instruments: selection, deliberation, alteration, feasibility, testing and formal approval. The process was conducted in collaboration with the instruments' developer. A multidisciplinary working group of experts identified equivalence issues and suggested modifications. Focus group discussions with informants highlighted comprehension issues. Subsequently modified instruments were thoroughly tested. Finally, the instruments' developer approval further validated the qualitative adaptation. The study proposes a rigorous and systematic model to effectively achieve cultural adaptation of psychometric instruments.

Organophosphorus compound (OPC) poisoning is common in Bangladesh. The toxicity of the agent and paucity of appropriate medical services has resulted in high mortality rates. To find out the clinical profile and outcome of OPC poisoning patients is the main aim of my study. This descriptive cross-sectional study was conducted in the Department of Medicine, Mymensingh Medical College Hospital, Bangladesh from September 2016 to November 2018. In this study, mean age of the study subjects was 25.90±11.24 years. Males (70.8%) were predominant than female (29.2%). In this study, most of the poisoning was done by ingestion (98.3%) and only two (1.7%) by inhalation. Regarding features, most muscarinic effect was constricted pupil and bronchospasm (65.0%). Common nicotinic effect was fasciculation (25.0%) and central effect was headache (61.67%). Mean amount of OPC ingestion was 26.30±17.24 ml in this study. Regarding circumstances of poisoning, familial disharmony (38.3%) and quarrel with other family members (37.5%) were the major reason followed by failure of personal affairs (15.0%) and other reasons (9.2%). Regarding complications, aspiration pneumonia was found in 6.7% cases, cardiac arrhythmia was in 6.7% cases and intermediate syndrome was in 1.7% cases. Most of the study subjects (95.0%) recovered fully. Most of the patients were from rural area. Suicidal was the common motive and familial disharmony and quarrel with other family members are the common circumstances of poisoning. Mortality rate was 5.0%.

The iPSC-derived 3D models are considered to be a connective link between 2D culture and in vivo studies. However, the sensitivity of such 3D models is yet to be established. We assessed the sensitivity of the hiPSC-derived 3D spheroids against 2D cultures of neural progenitor cells. The sub-toxic dose of Sodium Arsenite (SA) was used to investigate the alterations in miRNA-proteins in both systems. Though SA exposure induced significant alterations in the proteins in both 2D and 3D systems, these proteins were uncommon except for 20 proteins. The number and magnitude of altered proteins were higher in the 2D system compared to 3D. The association of dysregulated miRNAs with the target proteins showed their involvement primarily in mitochondrial bioenergetics, oxidative and ER stress, transcription and translation mechanism, cytostructure, etc., in both culture systems. Further, the impact of dysregulated miRNAs and associated proteins on these functions and ultrastructural changes was compared in both culture systems. The ultrastructural studies revealed a similar pattern of mitochondrial damage, while the cellular bioenergetics studies confirm a significantly higher energy failure in the 2D system than to 3D. Such a higher magnitude of changes could be correlated with a higher amount of internalization of SA in 2D cultures than in 3D spheroids. Our findings demonstrate that a 2D culture system seems better responsive than a 3D spheroid system against SA exposure.

BACKGROUND: In Pakistan, 84% of healthcare is provided by the private sector. We conducted an epidemiological and programme review for TB to document progress and guide further efforts. METHODS: Surveillance and data systems were assessed before analysing epidemiological data. We reviewed the programme at federal, provincial and peripheral levels and compiled national data along with WHO estimates to describe the evolution of epidemiological and programme indicators. RESULTS: In 2021, of the estimated number of TB cases, 55% of overall cases and 18% of drug-resistant cases were diagnosed and treated respectively. The contribution of the private sector in case detection increased from 30% in 2017 to 40% by 2021. For newly diagnosed pulmonary TB cases, the overall proportion of confirmed cases was 52%. In 2021, testing for rifampicin resistance among confirmed cases was 66% for new and 84% for previously treated patients. The treatment success rate exceeded 90% for drug susceptible TB. The main challenges identified were a funding gap (60% in 2021-2023), fragmented electronic systems for data collection and suboptimal coordination among provinces. CONCLUSIONS: The main challenges prevent further progress in controlling TB. By addressing these, Pakistan could improve coverage of interventions, including diagnosis and treatment. Bacteriological confirmation using recommended diagnostics also requires further optimisation.
CONTEXTE: Au Pakistan, le secteur privé assure 84% des services de santé. Une étude épidémiologique et programmatique a été réalisée sur la TB afin de recueillir des informations sur les avancées réalisées et de guider les actions à venir. MÉTHODES: Les systèmes de surveillance et de données ont été évalués préalablement à l'analyse des données épidémiologiques. Nous avons examiné le programme aux niveaux fédéral, provincial et local et compilé les données nationales ainsi que les estimations de l'OMS afin de décrire l'évolution des indicateurs épidémiologiques et du programme. RÉSULTATS: En 2021, environ 55% de l'ensemble cas de TB et 18% des cas résistants aux médicaments ont été diagnostiqués et traités respectivement. La contribution du secteur privé dans la détection des cas est passée de 30% en 2017 à 40% en 2021. La proportion totale de cas confirmés pour les nouveaux diagnostics de TB pulmonaire s'élevait à 52%. En 2021, les tests de résistance à la rifampicine parmi les cas confirmés s'élevaient à 66% pour les nouveaux patients et de 84% pour les patients déjà traités. Le taux de réussite du traitement a dépassé 90% pour la TB sensible aux médicaments. Les défis majeurs comprennent un manque de financement (60% pour la période 20212023), des systèmes électroniques de collecte de données fragmentés et une coordination insuffisante entre les provinces. CONCLUSIONS: Les défis majeurs entravent les avancées dans la lutte contre la TB. En les mettant en évidence, le Pakistan pourrait améliorer la portée des interventions, y compris le diagnostic et le traitement. Il est également essentiel d'optimiser la confirmation bactériologique en utilisant les diagnostics recommandés.
RESUMEN
Stroke, usually a focal rather than global neurological deficit resulting from vascular origin with sudden onset, may be with cerebral infarction or intracerebral haemorrhage. It results in brain oedema following vascular injury and electrolyte imbalance. A descriptive cross sectional study was carried out in the Department of Medicine, Mymensingh Medical College Hospital, Mymensingh, Bangladesh during March 2016 to May 2018 to assess the electrolyte levels among 220 purposively selected patients with stroke confirmed by CT scan. Data were collected by the principal investigator himself by using interview schedule and case record form after attaining consent. Blood samples were collected from the patients to carry out biochemical and haematological tests and to assess serum electrolyte levels. Data were cross-checked for completeness, consistency and relevancy, and were analyzed by computer software SPSS 20.0. Age was significantly higher in haemorrhagic stroke (64.88±13.00 years) than ischaemic stroke (60.92±13.96 years). Male (55.91%) were predominant than female (44.09%). One hundred nineteen (54.09%) patients had ischaemic stroke and 101(45.91%) patients had haemorrhagic stroke. The serum concentration of Na+, K+, Cl- and HCO3- were measured during acute period of stroke. Imbalance in serum Sodium, Chloride, Potassium and Bicarbonate level were observed in 37.27%, 29.55%, 23.18% and 6.36% patients respectively. Hyponatremia, hypokalemia, hypochloremia and acidosis were most common electrolyte imbalance in both ischaemic and haemorrhagic strokes. In ischaemic stroke hyponatremia was 35.29%, hypernatremia was 3.36%, hypokalemia 19.33%, hyperkalemia 0.84%, hypochloraemia 30.25%, hyperchloraemia 3.36%, acidosis was in 6.72% and alkalosdis in 1.68% patients while in haemorrhagic stroke hyponatremia 33.66%, hypernatremia 1.98%, hypokalaemia 22.77% hyperkalemia 3.96%, hypochloremia 19.80%, hyperchloraemia 4.95%, acidosis 2.97% and alkalosis was in 0.99% of patients. Mortality was more in hyponatremic, hypokalemic and in hypochloremic patients.

Squalene synthase (SQS: EC 2.5.1.21) is a potential branch point regulatory enzyme and represents the first committed step to diverge the carbon flux from the main isoprenoid pathway towards sterol biosynthesis. In the present study, cloning and characterization of Withania somnifera squalene synthase (WsSQS) cDNA was investigated subsequently followed by its heterologous expression and preliminary enzyme activity. Two different types of WsSQS cDNA clones (WsSQS1and WsSQS2) were identified that contained an open reading frames of 1,236 and 1,242 bp encoding polypeptides of 412 and 414 amino acids respectively. Both WsSQS isoforms share 99 % similarity and identity with each other. WsSQS deduced amino acids sequences, when compared with SQS of other plant species, showed maximum similarity and identity with Capsicum annuum followed by Solanum tuberosum and Nicotiana tabacum. To obtain soluble recombinant enzymes, 24 hydrophobic amino acids were deleted from the carboxy terminus and expressed as 6X His-Tag fusion protein in Escherichia coli. Approximately 43 kDa recombinant protein was purified using Ni-NTA affinity chromatography and checked on SDS-PAGE. Preliminary activity of the purified enzymes was determined and the products were analyzed by gas chromatograph-mass spectrometer (GC-MS). Quantitative real-time PCR (qRT-PCR) analysis showed that WsSQS expresses more in young leaves than mature leaves, stem and root.

This study was aimed to formulate and evaluate anti-aging effects of a topical cream (w/o emulsion) containig extract of Fennel (Foeniculum vulgare) versus its base. Formulation containing 4% concentrated extract of Foeniculum vulgare was developed by entrapping in the inner aqueous phase of w/o emulsion and base contained no extract. Both the base and formulation were stored under different storage conditions to predict their stability. The formulation and base were evaluated for effect on skin moisture and transepidermal water loss (TEWL). The base showed insignificant while the formulation showed significant effects on skin moisture and TEWL. The parameter volume and surface evaluation of living skin (SELS) parameters SEr, SEsc, SEsm, SEw were also evaluated and showed a significant (p < or = 0.05) decline. The texture parameter energy showed a significant increase proving that the formulation possesses potential anti-aging effects.

This study explores the antioxidant activity, phytochemical screening, total phenolic and flavonoids contents in the extracts of four locally available weeds plants namely Convolvulus arvensis, Chenopodium murale, Avena fatua and Phalaris minor with different solvents. The antioxidant activities of these extracts were determined via various in-vitro methods such as total antioxidant activity (TAA), reducing power (RP), DPPH (2,2-Diphenyl-1-Picrylhydrazyl) free radical scavenging and hydrogen peroxide scavenging assays. Phytochemical screening was performed both qualitatively as well as quantitatively. Total phenolic content (TPC) and total flavonoid content (TFC) were determined through Folin- Ciocalteu reagent and aluminium chloride methods respectively. Methanol-chloroform solvent showed the presence of a high amount of TPC in milligram of gallic acid equivalent per gram of dry weight (mg of GAE/g of DW) in the extracts of all weeds. Their descending sequence was Avena fatua (74.09) Ë Phalaris minor (65.66) Ë Chenopodium murale (64.04) Ë Convolvulus arvensis (61.905), while, chloroform solvent found to be best solvent for the extraction of TFC. Methanol-chloroform solvent was also found to be best solvent for TAA (Total antioxidant activity assay) which showed values in milligram of ascorbic acid equivalent per gram of dry weight (mg of AAE /g of DW), for DPPH scavenging activity, reducing power (antioxidant activity) and hydrogen peroxide scavenging activity. Phytochemical screening indicated the presence of polyphenols, flavonoids, tannins, saponins, alkaloids and glycosides in these weeds.

Liver fibrosis is initial stage of any chronic liver disease and its end stage is develops into cirrhosis. Chronic liver diseases are a crucial global health issue and the cause of approximately 2 million deaths per year worldwide. Cirrhosis is currently the 11th most common cause of death globally. Mesenchymal stem cell (MSCs) treatment is the best way to treat acute and chronic liver disease. The aim of this study is to improve the therapeutic potential of MSCs combined with melatonin (MLT) to overcome CCl4-induced liver fibrosis and also investigate the individual impact of melatonin and MSCs against CCl4-induced liver impairment in animal model. Female BALB/c mice were used as CCL4-induced liver fibrotic animal model. Five groups of animal model were made; negative control, Positive control, CCl4+MSCs treated group, CCl4+MLT treated group and CCl4+MSCs+MLT treated group. Cultured MSCs from mice bone marrow were transplanted to CCl4-induced liver injured mice model, individually as well as together with melatonin. Two weeks after MSCs and MLT administration, all groups of mice were sacrificed for examination. Morphological and Histopathological results showed that combined therapy of MSCs+MLT showed substantial beneficial impact on CCl4-induced liver injured model, compared with MSCs and MLT individually. Biochemically, considerable reduction was observed in serum bilirubin and ALT levels of MLT+MSC treated mice, compared to other groups. PCR results shown down-regulation of Bax and up-regulation of Bcl-xl and Albumin, confirm a significant therapeutic effect of MSCs+MLT on CCI4-induced liver fibrosis. From the results, it is concluded that combined therapy of MSCs and MLT show strong therapeutic effect on CCL4-induced liver fibrosis, compared with MSCs and MLT individually.

Human metapneumovirus (hMPV) is an emerging human pulmonary pathogen that is genetically related to respiratory syncytial virus. It has been increasingly associated with respiratory illnesses over the last few decades. Immunocompromised patients are particularly susceptible with resultant morbidity and mortality. We describe our experience with 9 immunocompromised patients diagnosed with pneumonia secondary to hMPV, 2 of whom were successfully treated with aerosolized and oral ribavirin along with intravenous immunoglobulin (IVIG). We suggest that hMPV should be considered in the differential diagnosis of immunocompromised patients with acute respiratory illness. Ribavirin (oral and aerosolized) with IVIG is potentially an effective treatment option for those with severe disease.

STUDY DESIGN: Review. OBJECTIVES: In subjects with spinal cord injury (SCI), there is strong evidence for platelet hyperactivity, which may stimulate atherosclerosis and coronary heart disease (CHD). The literature was reviewed. BACKGROUND: Individuals with SCI develop premature CHD. In addition to the conventional risk factors associated with CHD, there are pathologic hematological factors involved in atherogenesis that are similar to those that have been demonstrated in individuals with diabetes, and these hematological factors might affect individuals with SCI. One such hematological factor, platelet aggregation, is essential for the development of CHD, which results from thrombus formation in the coronary vasculature. Prostacyclin (PGI(2)) is a potent inhibitor of platelet aggregation and is thought to have a beneficial role in inhibiting atherogenesis; therefore, it is possible that individuals with SCI have impaired PGI(2) receptor function. METHODS: We reviewed the literature by conducting a search using PubMed (1970-2007). RESULTS: Acute thrombosis is emerging as an important factor in the etiology of CHD and therefore could mediate the risk of CHD in persons with SCI, in addition to previously known risk factors such as hyperlipidemia, hypertension, hyperlipidemia, diabetes mellitus and hyperinsulinemia. Because PGI(2) may retard atherogenesis through its inhibitory effects on platelet function, we discuss the effects of PGI(2) on platelets in persons with SCI in this review. CONCLUSIONS: Subjects with chronic SCI develop abnormal platelet function, resulting in the production of atherogenic and thrombogenic factors for the following reasons: (1) the PGI(2) and insulin receptors on their platelets are impaired; (2) thrombin generation and platelet-derived growth factor release are elevated; (3) insulin-induced nitric oxide production by platelets is markedly impaired; and (4) a circulating antibody (immunoglobulin G (IgG)) blocks the antithrombotic effect of both insulin and PGI(2) receptors. Thus, this IgG molecule is thought to be one of the pathological mediators of the increased incidence of CHD in individuals with SCI.

This study aimed to identify the phylogenetic similarities among the muntjac (Muntiacus spp.). The phylogenetic similarities among seven major muntjac species were studied by comparing the nucleotide sequence of 16s rRNA and cytochrome b genome. Nucleotide sequences, retrieved from NCBI databases were aligned by using DNASTAR software. A phylogenetic tree was created for the selected species of muntjac by using the maximum likelihood method on MEGA7 software. The results of nucleotide sequences (16s rRNA) showed phylogenetic similarities between, the M. truongsonensis and M. rooseveltorum had the highest (99.2%) while the lowest similarities (96.8%) found between M. crinifrons and M. putaoensi. While the results of nucleotide sequences (Cty b) showed the highest similarity (100%) between M. muntjak and M. truongsonensis and the lowest s (91.5%) among M. putaoensis and M. crinifrons. The phylogenetic tree of muntjac species (16s rRNA gene) shows the main two clusters, the one including M. putaoensis, M. truongsonensis, M. rooseveltorum, and M. muntjak, and the second one including M. crinifrons and M. vuquangensis. The M. reevesi exists separately in the phylogenetic tree. The phylogenetic tree of muntjac species using cytochrome b genes shows that the M. muntjak and M. truongsonensis are clustered in the same group.

OBJECTIVE: Diabetes mellitus is a chronic metabolic disease which has an adverse impact on the quality of patient's life, so patients often need to receive treatment for a long time. Selection of medications with high therapeutics effects and low cost is very important for patients to take medicine for a longer period of time. Sitagliptin is a drug which is widely used in clinics and can effectively control blood glucose level. This article explores the pharmacoeconomic value of Sitagliptin in the treatment of diabetes mellitus. PATIENTS AND METHODS: A total of 100 patients with diabetes mellitus treated were recruited in this study. The patients were randomly divided into 4 groups with 25 cases in each group. Patients in group A were treated with pioglitazone, group B with Sitagliptin, group C with metformin and group D with glimepiride. The cost of the drugs, the treatment results and adverse effects were compared. RESULTS: Compared with group A, C and D, the cost-effectiveness ratio of group B was low (p<0.05), and the therapeutic effect was high (p<0.05). In addition, the incidence of adverse reactions in group B was lower than that in group A, C and D (p<0.05). There was no significant difference in the levels of FPG, 2hPG and HbAlc in patients among the four groups before treatment (p>0.05). After treatment, the levels of FPG, 2hPG and HbAlc in group B were significantly lower than those in groups A, C and D (p<0.05). Finally, there was no significant difference in waist circumference and BMI among the four groups before treatment (p>0.05). After treatment, the waist circumference and BMI in group B were lower than those in groups A, C and D (p<0.05). CONCLUSIONS: The application of Sitagliptin in the treatment of diabetic patients can effectively enhance the therapeutic effect.

Poisoning is one of the commonest methods employed for committing suicide, especially in Developing countries like Bangladesh. In this retrospective study, a total of 114 organophosphorus poisoningcases autopsied at Sir Salimullah Medical College morgue, Dhaka, Bangladesh, were analyzed during the period from January 2016 to December 2017. Male predominance was noted accounting for 75% of total cases compared to females 25% cases. Most common age group involved was 21-30 years 31% followed by 31-40 years 22% belonging to lower socioeconomic status. Suicide was the commonest manner of death in majority of cases. The reason may be the increasing stress in the family and economic constraints. Accidental deaths due to occupational exposure or inhalation of OPC compounds are reported but in these cases mortality rate is less than that suicidal poisoning. To reduce poisoning cases proper emphasis should be given for safe use of pesticides and consciousness should becreated among the population about poisonous compounds.
