Trends in managing femoral neck fractures with arthroplasty in the ≥ 50 years age group.

Objective: To know about the trends in the management of neck of femur fractures with arthroplasty in patients ≥ 50 years. Methods: It is a retrospective cross-sectional study with data collection from Hospital Management Information System from 1st January 2020 to 31st July 2023. SPSS version 25 was used for data analysis. Mean & standard deviation was reported for quantitative variable & frequency and proportion were reported for qualitative variables. The cross- tabulations were performed to evaluate the association between the variables. Results: Total number of patients in this study was 305. Mean age was 67.80 ± 10.5 SD. Male to female ratio was 150:155. Co-morbidities were found in 126 patients. The surgical options used were Austin Moore prosthesis (64), Cemented Bipolar (36), Hybrid Total Hip Replacement (7), Non-cemented Total Hip Replacement (86), Cemented Total Hip Replacement (32), Uncemented Bipolar (71). Garden Type-2 fracture was noted in 33 patients, Type-3 in 170 patients and Type-4 in 87 patients. Cemented stem was used in 74 patients while 222 patients had non-cemented stem. Conclusion: One quarter of the patients had cemented stem implanted compared to three quarter of the patients who had non-cemented stem.

Epidemiology of hip & knee replacement across Pakistan: Multicenter cross-sectional study.

Objective: To know about the predictive prevalence of hip and knee arthroplasty across Pakistan. Methods: It is retrospective cross-sectional study with data collection from Pakistan National Joint Registry (PNJR) of number of hip and knee arthroplasty cases in seven years (2014-2021). Fourteen high volume centers across Pakistan who consented for data publication were included. Stata version 16 was used for data analysis. Mean & standard deviation was reported for quantitative variable & frequency and proportion were reported for qualitative variables. Results: Our results showed a total of 9572 people had total knee replacement in last seven years from 2014-2021 with the rate of 9.57/100,000 population. Mean age of the patient was 61.7±8.95 with 69.5% patients being female and 30.5% being male. Our results showed a total of 2265 people had total hip replacement in last seven years from 2014-2021with the rate of 2.26/100,000 population. Mean age of the patient was 50.7±15.4 with 62% patients being male and 38% being female. Conclusion: This is the first epidemiological study in Pakistan on the rates of hip and knee arthroplasty cases in Pakistan based on registry data, showing that more knee arthroplasty cases are being performed as compared to hip arthroplasty.

A comprehensive review of the pharmacological potential of Crocus sativus and its bioactive apocarotenoids.

Crocus sativus is an herbaceous plant that belongs to family Iridaceae. It is commonly known as saffron and has been used for medicinal purposes since many centuries in India and other parts of the world. Saffron of commercial importance comprises of dried stigmas of the plant and is rich in flavonoids, vitamins, and carotenoids. Carotenoids represent the main components of saffron and their cleavage results in the formation of apocarotenoids such as crocin, picrocrocin, and safranal. Studies conducted during the past two decades have revealed the immense therapeutic potential of saffron. Most of the therapeutic properties are due to the presence of unique apocarotenoids having strong free radical scavenging activity. The mode of action of these apocarotenoids could be: modulatory effects on detoxifying enzymes involved in combating oxidative stress, decreasing telomerase activity, increased the proapoptotic effect, inhibition of DNA, RNA and protein synthesis, and by a strong binding capacity of crocetin with tRNA. The present review focuses on the therapeutic role of saffron and its bio oxidative cleavage products and also highlights the possible molecular mechanism of action. The findings reported in this review describes the wide range of applications of saffron and attributes its free radical scavenging nature the main property which makes this spice a potent chemotherapeutic agent for the treatment of various diseases.

OUTCOME OF OPERATIVE TREATMENT OF ACETABULAR FRACTURES: SHORT TERM FOLLOW-UP.

BACKGROUND: Fractures of the acetabulum result from high energy accidents. The anatomic location of the acetabulum, as well as the three-dimensional structure of the bone, makes the treatment of these injuries extremely challenging. The objective of this study was to determine the outcome of operative treatment of acetabulum fractures with one year follow-up. METHODS: In this descriptive case series, 31 patients with-acetabular fracture were admitted in North West General Hospital, Peshawar, from July 2010 to Sept 2013. Patients were followed-up till one year. In follow-up, patients were assessed clinically with Merle d' Aubigne and Postel grading method. Radiological assessment was done using Matta criteria. RESULTS: All patients were male. Twelve (38.7%) were managed non-operatively, as they fulfilled criteria for non-operative treatment and 19 (61.3%) patients were operated after fulfilling the criteria for internal fixation; they were included for analysis. Ages ranged from 20-60 years with mean age of 37.21 +/- 10.07 years. Fourteen (73.7%) patients had anatomic reduction and 5 (26.3%) patients had imperfect reduction based on Matta radiographic criteria. At 1 year follow-up, we had 16 (84.2%) excellent hips, 2 (10.5%) good hips and 1 (5.3%) poor hip, based on radiographs; and clinically we had 9 (47.4%) hips with excellent function, 7 (36.8%) hips with good outcome, 2 (10.5%) had fair function and 1 (5.3%) patient had poor function. CONCLUSION: Our results show that internal fixation of acetabular fractures lead to good outcome in maiority of patients.

Safranal of Crocus sativus L. inhibits inducible nitric oxide synthase and attenuates asthma in a mouse model of asthma.

The present study involves evaluation of antioxidant potential of Crocus sativus and its main constituents, safranal (SFN) and crocin (CRO), in bronchial epithelial cells, followed antiinflammatory potential of the active constituent safranal, in a murine model of asthma. To investigate the antioxidizing potential of Crocus sativus and its main constituents in bronchial epithelial cells, the stress was induced in these cells by a combination of different cytokines that resulted in an increase in nitric oxide production (NO), induced nitric oxide synthase (iNOS) levels, peroxynitrite ion generation, and cytochrome c release. Treatment with saffron and its constituents safranal and crocin resulted in a decrease of NO, iNOS levels, peroxynitrite ion generation, and prevented cytochrome c release. However, safranal significantly reduced oxidative stress in bronchial epithelial cells via iNOS reduction besides preventing apoptosis in these cells. In the murine model of asthma study, antiinflammatory role of safranal was characterized by increased airway hyper-responsiveness, airway cellular infiltration, and epithelial cell injury. Safranal pretreatment to these allergically inflamed mice lead to a significant decrease in airway hyper-responsiveness and airway cellular infiltration to the lungs. It also reduced iNOS production, bronchial epithelial cell apoptosis, and Th2 type cytokine production in the lungs.

Linking GATA-3 and interleukin-13: implications in asthma.

INTRODUCTION: Asthma is one of the serious global health problems and cause of huge mortality and morbidity. It is characterized by persistent airway inflammation, airway hyperresponsiveness, increased IgE levels and mucus hypersecretion. Asthma is mediated by dominant Th2 immune response, causing enhanced expression of Th2 cytokines. These cytokines are responsible for the various pathological changes associated with allergic asthma. MATERIALS AND METHODS: The role of Th2 cells in the pathogenesis of the asthma is primarily mediated through the cytokine IL-13, also produced by type 2 innate lymphoid cells, that comes under the transcriptional regulation of GATA3. In this review we will try to explore the link between IL-13 and GATA3 in the progression and regulation of asthma and its possible role as a therapeutic target. CONCLUSION: Inhibition of GATA3 activity or blockade of GATA3 expression may attenuate the interleukin-13 mediated asthma phenotypes. So, GATA3 might be a potential therapeutic target for the treatment of allergic asthma.
