RESUMO
Rheumatoid arthritis (RA) is a common chronic immune-mediated inflammatory arthritis, impacting 0.5-1% of the global population, and leading to progressive deterioration of the musculoskeletal and joint systems. This study aims to analyze the serum levels of soluble triggering receptors expressed on myeloid cells-1 (sTREM-1) in Iraqi patients with RA and healthy individuals. It also intends to assess the diagnostic significance of these receptors, investigate their association with disease activity and examine their correlation with the sociodemographic and clinical characteristics of the patients. From December 2020 to June 2021, 117 RA patients with a mean age of 50 years participated in the study. The patients were categorized into inactive and active disease groups based on their DAS28 score and CDAI, as determined by a Rheumatologist. The serum levels of a specific triggering receptor expressed on myeloid cells-1 (TREM-1) (Pg/mL) were measured. The results showed that the active RA patients had significantly higher levels of the receptor (270.17±187) compared to both the inactive RA patients (112.81±37.48) and the healthy controls (43.89±29.53) (P < 0.001). The sTREM-1 demonstrated a high discriminatory ability (AUC ≥ 0.936) between RA and control groups. Moreover, a direct association was observed between the DAS-28ESR and sTREM-1 levels.

Prevalence of parasitic skin diseases, cutaneous leishmaniasis is very frequent in Pakistan, especially in Baluchistan where occurrence of phelbotomine sand flies (vector of protozoan parasite of genus Leishmania) is very common. This study was conducted to assess the antileishmaniasis activity of Intericutol plus ointment (2% and 3%) made with ethanolic extract of bark and leaves of Holoptelea integrifolia (Roxb.)Planch. The antileishmaniasis effect was observed by applying the ointments on the lesions of leishmaniasis patients. 150 patients were included in the study that had single and multiple painful wet and dry ulcerative lesions on the exposed area of the body. The patients were divided into two groups of 75 patients each, applying 2% and 3% ointment respectively for 28 days. Dose of 10gm/week was applied topically on wounds. Excellent antileishmaniasis effect was observed with significant quick healing properties in the patients receiving 3% Intericutol plus ointment as compare to 2% showing 89% and 81% cure (p=0.02) respectively. It can be concluded that ointment made from medicinal plant proved to be very effective in treating cutaneous Leishmaniasis.

The fashion industry cannot use 3 D Body Scanning to create custom garment patterns because its measurements fail to meet ISO 20685:2010's tolerances. To advance 3 D Body Scanning's precision, we present Gryphon: an algorithm that removes the two most extreme measurements from five body scans; removing potentially erroneous data. We assess Gryphon's precision against current industry practice, determine if consecutive and non-consecutive data capture influences precision, and determine 3 D Body Scanning's inherent imprecision inherent. We analyse 97 participants over 121 industry-standard measurements for consecutive and non-consecutive data-capture through MANOVA statistical analysis. Under current industry practice, only one measurement meets ISO 20685. However, under Gryphon and consecutive scanning, 97.5% of measurements meet ISO 20685. We also prove that the body's in-scan movement does not affect reliability. Ultimately, we offer the fashion industry, ergonomists, and practitioners an accessible method to increase 3 D Body Scanning's precision at a level unavailable under previous methods. Practitioner Summary: Ergonomists need precise data, yet we prove 0% of 3 D Body Scanning's measurements meet ISO 20685's tolerances. Our analysis of 97 participants scans, shows consecutive scanning is necessary to achieve data suitable for anthropometric applications. We develop the Gryphon process with consecutive scanning, making 97.3% of measurements meet ISO 20685.

BACKGROUND: Malignant pleural effusion (MPE) is a common, serious problem predominantly seen in metastatic lung and breast cancer and malignant pleural mesothelioma. Recurrence of malignant pleural effusion is common, and symptoms significantly impair people's daily lives. Numerous treatment options exist, yet choosing the most suitable depends on many factors and making decisions can be challenging in pressured, time-sensitive clinical environments. Clinicians identified a need to develop a decision support tool. This paper reports the process of co-producing an initial prototype tool. METHODS: Creative co-design methods were used. Three pleural teams from three disparate clinical sites in the UK were involved. To overcome the geographical distance between sites and the ill-health of service users, novel distributed methods of creative co-design were used. Local workshops were designed and structured, including video clips of activities. These were run on each site with clinicians, patients and carers. A joint national workshop was then conducted with representatives from all stakeholder groups to consider the findings and outputs from local meetings. The design team worked with participants to develop outputs, including patient timelines and personas. These were used as the basis to develop and test prototype ideas. RESULTS: Key messages from the workshops informed prototype development. These messages were as follows. Understanding and managing the pleural effusion was the priority for patients, not their overall cancer journey. Preferred methods for receiving information were varied but visual and graphic approaches were favoured. The main influences on people's decisions about their MPE treatment were personal aspects of their lives, for example, how active they are, what support they have at home. The findings informed the development of a first prototype/service visualisation (a video representing a web-based support tool) to help people identify personal priorities and to guide shared treatment decisions. CONCLUSION: The creative design methods and distributed model used in this project overcame many of the barriers to traditional co-production methods such as power, language and time. They allowed specialist pleural teams and service users to work together to create a patient-facing decision support tool owned by those who will use it and ready for implementation and evaluation.

Spectrophotometric technique is considered to be the simplest and operator friendly among other available analytical methods for pharmaceutical analysis. The objective of the study was to develop a precise, accurate and rapid UV-spectrophotometric method for the estimation of chlorpheniramine maleate (CPM) in pure and solid pharmaceutical formulation. Drug absorption was measured in various solvent systems including 0.1N HCl (pH 1.2), acetate buffer (pH 4.5), phosphate buffer (pH 6.8) and distil water (pH 7.0). Method validation was performed as per official guidelines of ICH, 2005. High drug absorption was observed in 0.1N HCl medium with λmax of 261nm. The drug showed the good linearity from 20 to 60µg/mL solution concentration with the correlation coefficient linear regression equation Y= 0.1853 X + 0.1098 presenting R2 value of 0.9998. The method accuracy was evaluated by the percent drug recovery, presents more than 99% drug recovery at three different levels assessed. The % RSD value <1 was computed for inter and intraday analysis indicating the high accuracy and precision of the developed technique. The developed method is robust because it shows no any significant variation in with minute changes. The LOD and LOQ values were assessed to be 2.2µg/mL and 6.6µg/mL respectively. The investigated method proved its sensitivity, precision and accuracy hence could be successfully used to estimate the CPM content in bulk and pharmaceutical matrix tablets.

This study assessed the prescribing pattern of irrational use of antibiotic among children under age of 12 years in public and private sector hospitals in Pakistan. The prospective clinical evaluation of drug utilization pattern of antimicrobials from Patient Bedside File (PBF) of in-patients and Culture Sensitivity Test (CST) reports were evaluated to determine the antibiotic resistance. Two indicators recorded to assess antibiotic prescribing were; dose of prescribed antibiotic (low-dose, rational and high -dose) and Indication (valid or invalid). Antibiotics resistance for 25 selected antibiotics was determined by culture sensitivity test. This study showed that in Private Sector Hospital 77.7% neonates, 13.3% infants and 9% children admitted in ICU were receiving antibiotics, among them only 57.3% neonates, 62% infants and 59.9% children were found valid that is prescribed antibiotics for right indication. 27% neonates, 19% infants and 22.1% children were prescribed under dose of antibiotics, which may lead to antimicrobial resistance and increased cost of hospital stay. Only 29.1% neonates, 30% infants and 36.8% children were receiving rational dosing. In Public Sector Hospital, 65.6% neonates, 19.4% infants and 15% children were receiving antibiotics. Among them valid indication was found in 35.3% neonates, 35.6% infants and 39.8% in children. 33.3% neonates, 26.6% infants and 28.2% children were receiving under dose that may lead to resistance not only among those who were prescribed under dose but also such bacteria become resistant and spread to other population to increase antimicrobial resistance. The irrational prescribing of antibiotics was found very high (above 50%) in Public sector hospital (Hospital-B) for every age group whereas in Private sector hospital (Hospital-A) this practice was found near to 50%. In this study the prescribing frequency of Amikacin, Cefixime, Cefotaxime, Meropenem, Amoxicillin, Vancomycin, Azithromycin, Levofloxacin and Clarithromycin was found above 80% in both hospitals (A and B). Among these, Amoxicillin, Penicillin, Erythromycin and Cephalexin showed higher resistance i.e. 49.2%.

Vesicular stomatitis virus (VSV) vectors that express heterologous antigens have shown promise as vaccines in preclinical studies. The efficacy of VSV-based vaccines can be improved by engineering vectors that enhance innate immune responses. We previously generated a VSV vaccine vector that incorporates two enhancing strategies: an M protein mutation (M51R) that prevents the virus from suppressing host antiviral responses and a gene encoding bacterial flagellin (M51R-F vector). The rationale was that intracellular expression of flagellin would activate innate immune pathways in addition to those activated by virus alone. This was tested with dendritic cells (DCs) from mice containing deletions in key signaling molecules. Infection of DC with either M51R or M51R-F vector induced the production of interleukin-12 (IL-12) and IL-6 and increased surface expression of T cell costimulatory molecules. These responses were dramatically reduced in DCs from IPS-1(-/-) mice. Infection with M51R-F vector also induced the production of IL-1ß. In addition, in approximately half of the DCs, M51R-F vector induced pyroptosis, a proinflammatory-type of cell death. These responses to flagellin were ablated in DCs from NLRC4(-/-) mice but not Toll-like receptor 5-deficient (TLR5(-/-)) mice, indicating that they resulted from inflammasome activation. These results demonstrate that flagellin induces additional innate immune mechanisms over those induced by VSV alone.

The percentage of overweight and obese person has increased markedly since several decays. Obesity is associated with increased risked factor for many diseases such as, diabetes, heart complications, arthritis and certain types of cancer. Feeding behavior is in controlled by a major interaction between central nervous system and many organs of the body. The role of serotonin (5-HT) in feeding behavior is well recognized. The aim of present study was to evaluate the effect of Anethum graveolens seeds aqueous extract (AGAE) on food intake, body weight and serotonin metabolism in over weight rats. Five weeks oral administration of AGAE shows significant decrease in body weight, food intake and significant increase in whole brain 5-HT, 5-HIAA and tryptophan level in brain and plasma of experimental animals. Increased level of 5-HT induced satiety and suppressed food intake and result is the reduction in body weight.

Inhibition of host-directed gene expression by the matrix (M) protein of vesicular stomatitis virus (VSV) effectively blocks host antiviral responses, promotes virus replication, and disables the host cell. However, dendritic cells (DC) have the capacity to resist these effects and remain functional during VSV infection. Here, the mechanisms of DC resistance to M protein and their subsequent maturation were addressed. Flt3L-derived murine bone marrow dendritic cells (FDC), which phenotypically resemble resident splenic DC, continued to synthesize cellular proteins and matured during single-cycle (high-multiplicity) and multicycle (low-multiplicity) infection with VSV. Granulocyte-macrophage colony-stimulating factor (GM-CSF)-derived myeloid DC (GDC), which are susceptible to M protein effects, were nevertheless capable of maturing, but the response was delayed and occurred only during multicycle infection. FDC resistance was manifested early and was type I interferon (IFN) receptor (IFNAR) and MyD88 independent, but sustained resistance required IFNAR. MyD88-dependent signaling contributed to FDC maturation during single-cycle infection but was dispensable during multicycle infection. Similar to FDC, splenic DC were capable of maturing in vivo during the first 24 h of infection with VSV, and neither Toll-like receptor 7 (TLR7) nor MyD88 was required. We conclude that FDC resistance to M protein is controlled by an intrinsic, MyD88-independent mechanism that operates early in infection and is augmented later in infection by type I IFN. In contrast, while GDC are not intrinsically resistant, they can acquire resistance during multicycle infection. In vivo, splenic DC resist the inhibitory effects of VSV, and as in multicycle FDC infection, MyD88-independent signaling events control their maturation.

Prolonged and intensive exercise induces transient immunosuppression and is associated with an increased risk and severity of infections. The goal of this study was to characterize the antiviral and antibacterial properties of the bioactive metabolites of a blueberry-green tea-polyphenol soy protein complex (PSPC) in the serum of supplemented subjects during a 3-day intensified training period. Long-distance runners, randomly divided into two groups, ingested 40 g/day PSPC or placebo (soy protein and colorings) for 17 days, with a 3-day running period inserted at day 14. Blood serum samples were collected pre-14 days and post-14 days supplementation, and immediately and 14 h after the third day of running. The post-exercise serum from both groups significantly promoted the growth of Escherichia coli and Staphylococcus aureus in culture by 20-70%, but returned to normal levels following recovery. Furthermore, the serum from subjects ingesting PSPC did not display antibacterial properties at any time point. In contrast, there was a significant difference in the ability of serum from PSPC-supplemented versus placebo-supplemented athletes to protect cells in culture from killing by vesicular stomatitis virus following strenuous exercise. In addition, the serum of subjects who ingested PSPC significantly delayed an exercise-induced increase in virus replication. These results indicate that polyphenol complexes containing blueberry and green tea have the potential to protect athletes from virus infections following rigorous exercise.

Trigonella foenum- graecum Linn (Fabaceae) is an annual aromatic herb and no wit is cultivated globally like in Pakistan, Egypt, India, Middle East etc. Traditionally it was used in anorexia, as febrifuge, to soothe gastritis and gastric ulcers, as a galactagogue and as condiment, hypoglycemic agent and employed in various as nervous disorders. The study aimed to investigate the antidepressant effect of ethanolic extract of seeds of Trigonella foenum graecum and underlying mechanism of action. For assessment of antidepressant activity Forced Swimming Test (FST), Tail Suspension Test (TST), Monoamine (MAO) Assay and Locomotor Activity Test were studied. Acute toxicity, Rota Rod and Grip Strength Tests were also performed. The significant declining in immobility time as compared to control was shown in Forced swimming test as compared to tail suspension test. Considerable change was not found in open field test (OFT). EtOH extract of seeds of fenugreek represent maximum significant reduction which was 30 and 24.65% in MAO- A and B activity respectively in the rat's whole brain as compared to control animals in Monoamine oxidase (MAO) assay. All tested doses were found ineffective in impairment of muscle coordination in Rota rod and in grip strength related to muscle relaxant property. According to experimental findings it is revealed that ethanolic extract of seeds of Trigonella foenum graecum showed antidepressant effect by inhibiting the activity of MAO-A and B.

Cancer is a common cause of death in human populations. Surgery, chemotherapy and radiotherapy still remain the corner stone of treatment. However, herbal medicines are gaining popularity on account of their lesser harmful side effects on non-targeted human cells and biological environment. Annona squamosa Linn is a common delicious edible fruit and its leaf have been used for the treatment in various types of diseases. The objective of present study is to determine the anticancer potential of the organic and aqueous extracts of leaf of Annona squamosa L. MTT (3-(4, 5-dimethylthiazole-2yl)-2, 5-biphenyl tetrazolium bromide) assay against hepatocellular carcinoma cell line BEL-7404, lung cancer line H460, human epidermoid carcinoma cell line KB-3-1, prostatic cancer cell line DU145, breast carcinoma cell line MDA-MB-435, and colon cancer cell line HCT-116 Human primary embryonic kidney cell line HEK293 as control were used for the study. The crude extract (Zcd) and Ethyl acetate extract (ZE) were found significant anticancer activity only on human epidermoid carcinoma cell line KB-3-1 and colon cancer cell line HCT-116.

BACKGROUND: Cardio embolism and cerebrovascular atherosclerosis are two major mechanisms of stroke. Studies investigating associations between advanced echocardiographic parameters and stroke mechanisms are limited. METHODS: This study is a standardized review of 633 patients admitted to the stroke service of a tertiary care hospital following a standardized stroke investigation and management pathway. Stroke subtypes were characterized using the Causative Classification System, using the hospitals online radiologic archival system with CCS certified stroke investigators. Patients with two mechanisms were excluded. RESULTS: Patients with cardioembolic stroke had a higher proportion of atrial fibrillation (p < 0.001), acute myocardial infarction (p < 0.001) and ischemic heart disease (p < 0.001). On electrocardiogram (ECG) and transthoracic Echo (TTE), patients with cardioembolic stroke had a greater atrial fibrillation (p < .00), left ventricular thrombus (p < .00), left ventricular ejection fraction <30% (p < .00) and global hypokinesia (p < .00) Patients with cardioembolic stroke had higher mean left atrial volume indices (LAVi) (p < 0.001), mean left ventricular mass indices (LVMi) (p < 0.05) and mean left atrial diameters (LAD) (p < 0.05). At LAVi of 29-33 ml/m2, the risk of atherothrombotic stroke increased. The risk of cardioembolic stroke increased with LAVi of 34 ml/m2 and above. CONCLUSION: Left atrial volume indices may be linked to specific stroke phenotype. At mild increases in left atrial dimensions, the risks of atherosclerotic stroke are high, and probably reflect hypertension as the unifying mechanism. Further increases in left atrial dimensions shifts the risk towards cardioembolic stroke.

Cancer remains the major public health concern with a number of cancer patients relying on chemotherapy as a treatment option. Although, advances in biomedical research have led to increased anticancer agents in recent years, the treatment is not always effective due to resistance, toxicity or other factors. Phytochemicals and their active components isolated from plants have provided diversified effective drugs many of them are currently used against cancer and other diseases. Holoptelea integrifolia (Roxb) Planch (Ulmaceae) is a widely distributed plant in many parts of the world, also grown in gardens of Pakistan. It is an ornamental plant with certain medicinal characteristics due to many valuable and active phyto constituents in various parts of the plant. We looked at in vitro antineoplastic effects of four different extracts, in butanol (BMBU), hexane (BMHx), ethyl acetate (BMET) and chloroform (BMCHF), from bark of Holoptelea integrifolia on small cell lung cancer, breast, prostate, coloretal and hepatocellular cancer cell lines. Plant extracts BMHx and BMET showed significant cytotoxic effects on breast and prostate cancer cells. These preliminary studies are encouraging to proceed further this research in future, regarding the isolation of active phytoconstituents in these extracts as well as its mechanism in chemoprevention and combination anticancer therapy.

BACKGROUND: The incidence of hip fractures in the elderly is increasing. Minimally displaced and undisplaced hip fractures can be treated with either internal fixation or hemiarthroplasty. OBJECTIVES: To identify the revision rate of internal fixation and hemiarthroplasty in patients 60 years or older with Garden I or II hip fractures and to identify risk factors associated with each method. METHOD: A retrospective analysis was conducted from 2 Major Trauma Centres and 9 Trauma Units between 01/01/2015 and 31/12/2020. Patients managed conservatively, treated with a total hip replacement and missing data were excluded from the study. RESULTS: 1273 patients were included of which 26.2% (n = 334) had cannulated hip fixation (CHF), 19.4% (n = 247) had a dynamic hip screw (DHS) and 54.7% (n = 692) had a hemiarthroplasty. 66 patients in total (5.2%) required revision surgery. The revision rates for CHF, DHS and hemiarthroplasty were 14.4%, 4%, 1.2% (p<0.001) respectively. Failed fixation was the most common reason for revision with the incidence increasing by 7-fold in the CHF group [45.8% (n = 23) vs. 33.3% (n = 3) in DHS; p<0.01]. The risk factors identified for CHF revision were age >80 (p<0.05), female gender (p<0.05) and smoking (p<0.05). The average length of hospital stay was decreased when using CHF compared to DHS and hemiarthroplasty (12.6 days vs 14.9 days vs 18.1 days respectively, p<0.001) and the 1 year mortality rate for CHF, DHS and hemiarthroplasty was 2.5%, 2% and 9% respectively. CONCLUSIONS: Fixation methods for Garden I and II hip fractures in elderly patients are associated with a higher revision rate than hemiarthroplasty. CHF has the highest revision rate at 14.4% followed by DHS and hemiarthroplasty. Female patients, patients over the age of 80 and patients with poor bone quality are considered high risk for fixation failure with CHF. Hemiarthroplasty is a suitable alternative with lowest revision rates. When considering an internal fixation method, DHS is more robust than a screw construct.

Childhood obesity is a significant and growing issue, with the WHO recognising worldwide childhood obesity rates as an epidemic. Primary care is often the first point for monitoring a child's development over time, hence could play an integral part in recognising and addressing childhood obesity. As a result, our systematic review has two objectives. The primary objective is to review the current evidence on best practices in diagnosing and treating childhood obesity. The secondary objective is to review recent qualitative studies looking into the view of primary care practitioners on the treatment and diagnosis of childhood obesity. The rationale for this is to help determine what opportunities there are in primary care in the NHS to tackle childhood obesity. Using searches in MEDLINE, EMBASE, PSYCHINFO, HMIC and NHS evidence over a five-year period from March 2014 to March 2019, a total of 37 studies were eligible for inclusion in the review. Out of these, 25 studies identified exploring the diagnosis and treatment of childhood obesity. A few key themes in these studies were identified, including motivational interviewing, m-health, tools and resources used in consultations, the use of dieticians in the primary care team and factors concerned with the identification of obesity in children. The rest of the 12 qualitative studies involved eliciting the views of direct stakeholders about the diagnosis and treatment of obesity in children. Eight of the studies investigated providers' views towards the role of primary care practitioners in treating childhood obesity, two investigated the parents of obese children's perspectives and the other two investigated general practitioners' (GPs) views towards specific tools and resources. Regarding our primary objective, our findings showed many studies looking at interventions to reduce the BMI in obese children fail to do so in a statistically significant way. However, a few interventions have been more consistent in reducing BMI and obesogenic behaviours. Those interventions include ones utilising the motivational interviewing technique and those targeting families, rather than children. Another key finding was that tools and resources available to primary care providers can significantly impact their ability to diagnose and treat obesity, particularly when looking at the detection. Finally, evidence regarding the clinical effectiveness of e-health is limited, with views on their use also mixed. Regarding our secondary objective, the qualitative research identified demonstrated many common views from GPs across different countries. It showed healthcare providers (HCPs) perceiving the parents as lacking in motivation to address the issue, HCPs not wanting to damage the relationship with their patients due to it being a sensitive topic to bring up, and a lack of time, training and confidence. However, some of these views may not be generalisable to the UK due to cultural and system differences.
RESUMO
Vaccine-induced immune thrombocytopenia and thrombosis (VITT) following the adenoviral vector COVID-19 vaccine is a rare adverse event. Although the risk of VITT following the COVID-19 vaccine appears to be low, early diagnosis and management can be lifesaving. We present a case of VITT in a young female who presented with persistent headaches and fevers followed by anisocoria and right-sided hemiplegia. Initial imaging was unremarkable, and labs showed thrombocytopenia and elevated d-dimers. Repeat imaging revealed thrombosis in the left transverse and superior sagittal sinuses, and she was diagnosed with VITT. She received combined treatment with intravenous immunoglobulins and systemic anticoagulation, resulting in an increased platelet count and resolution of her neurological symptoms.
