Enhanced botnet detection in IoT networks using zebra optimization and dual-channel GAN classification.

The Internet of Things (IoT) permeates various sectors, including healthcare, smart cities, and agriculture, alongside critical infrastructure management. However, its susceptibility to malware due to limited processing power and security protocols poses significant challenges. Traditional antimalware solutions fall short in combating evolving threats. To address this, the research work developed a feature selection-based classification model. At first stage, a preprocessing stage enhances dataset quality through data smoothing and consistency improvement. Feature selection via the Zebra Optimization Algorithm (ZOA) reduces dimensionality, while a classification phase integrates the Graph Attention Network (GAN), specifically the Dual-channel GAN (DGAN). DGAN incorporates Node Attention Networks and Semantic Attention Networks to capture intricate IoT device interactions and detect anomalous behaviors like botnet activity. The model's accuracy is further boosted by leveraging both structural and semantic data with the Sooty Tern Optimization Algorithm (STOA) for hyperparameter tuning. The proposed STOA-DGAN model achieves an impressive 99.87% accuracy in botnet activity classification, showcasing robustness and reliability compared to existing approaches.

Effect of Lifestyle Modification Intervention Programme on Bone Mineral Density among Postmenopausal Women with Osteoporosis.

Objectives: Osteoporosis is one of the major public health problems worldwide among postmenopausal osteoporotic women. Lifestyle modification interventions along with pharmacotherapy help to revert bone loss and prevent complications. Methods: A randomised controlled trial was conducted at Kasturba Hospital, Manipal from January 2019 to December 2021 among postmenopausal women with osteoporosis. The postmenopausal women who attended the osteoporosis clinic and were within the age group of 45-65 years, could speak and understand English or Kannada and whose bone mineral density (BMD) score was between -1 and -3 were included in the study. The total sample size of the study was 120 with 60 in each of the experimental and control groups. After obtaining informed consent, a stratified block randomisation method was used to allocate the participants to intervention and control groups. The BMD was monitored by the portable ultrasound densitometer by a technician at the outpatient departments. The baseline information was collected by a structured demographic questionnaire. Intervention group participants received a lifestyle modification intervention program (LMIP) whereas the control group received standard regular care from the physician. Follow-up was done at three and six months. Results: The results revealed that the increase in the BMD median score among the experimental group was from -2.2 (-2.5- -1.8) to -1.5 (-1.8- -0.65) whereas in the control group, it was from -2.3 (-2.6- -1.9) to -2.0 (-2.4- -1.5). The results of the Mann Whitey U test showed a statistical significance between the intervention and control groups in the post-test after six months (U = 505.5; P <0.05). Wilcoxon signed rank test showed a significant change in both the intervention and control groups from pre-test to post-test I (3 months) and post-test II (6 months; P <0.001). Conclusion: The lifestyle modification intervention was found to be effective in improving the bone health status of postmenopausal women. Hence it is very important to integrate it into regular therapy.

Burden of Osteopenia and Osteoporosis Among Postmenopausal Women in India: A Systematic Review and Meta-Analysis.

Aim: Postmenopausal osteoporosis is a major public health problem around the world. The objective of this systematic review is to determine the prevalence of osteoporosis in postmenopausal women in India. Materials and Methods: This review was conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We identified relevant studies through a search of literature published from 2010 to January 2021 in the databases PubMed, Web of Science, ProQuest, CINHAL, and PEDro databases. We searched for cross-sectional studies involving India that were published in English. Results: There was a total of 1631 hits in the initial search and out of which 60 studies were selected for full-text review. Twelve studies were selected for qualitative analysis. Excluded studies were 48 with reasons: 20 studies had included other diseases such as knee arthritis, celiac diseases, diabetes mellitus, and kidney diseases. Eleven studies included premenopausal women, young adults, and men. Ten studies outcomes were different, and seven studies were excluded as they have done retrospective analysis and were commentaries. The pooled prevalence of osteoporosis at the lumbar spine region was 29%, the hip region was 6% and the femoral neck region was 29% whereas the pooled prevalence of osteopenia at the lumbar spine region was 37%, the hip was 6%, and femoral neck region was 37%. Conclusion: This systematic review found that postmenopausal women are at significant risk of developing low bone mineral density, and the prevalence of osteoporosis and osteopenia was high in the lumbar area.

An Enhanced Posture Prediction-Bayesian Network Algorithm for Sleep Posture Recognition in Wireless Body Area Networks.

Wireless body area networks have taken their unique recognition in providing consistent facilities in health monitoring. Several studies influence physiological signal monitoring through a centralized approach using star topology in regular activities like standing, walking, sitting, and running which are considered active postures. Unlike regular activities like walking, standing, sitting, and running, the in-bed sleep posture monitoring of a subject is highly necessary for those who have undergone surgery, victims of breathing problems, and victims of COVID-19 for whom oxygen imbalance is a major issue as the mortality rate in sleep is high due to unattended patients. Suggestions from the medical field state that the patients with the above-mentioned issues are highly suggested to follow the prone sleep posture that enables them to maintain the oxygen level in the human body. A distributed model of communication is used where mesh topology is used for the data packets to be carried in a relay fashion to the sink. Heartbeat rate (HBR) and image monitoring of the subject during sleep are closely monitored and taken as input to the proposed posture prediction-Bayesian network (PP-BN) to predict the consecutive postures to increase the accuracy rate of posture recognition. The accuracy rate of the model outperforms the existing classification and prediction algorithms which take the cleaned dataset as input for better prediction results.

Efficacy and safety of CARTIGROW® in patients with articular cartilage defects of the knee joint: a four year prospective studys.

INTRODUCTION: Research shows autologous chondrocyte implantation (ACI) is a promising treatment for articular cartilage lesions. In this study, we assessed mid-term efficacy and safety of gel-based ACI or autologous adult live cultured chondrocytes (CARTIGROW®) implantation in patients with cartilage defects of the knee joint. METHODS: In this prospective, open-label study, patients (19-38 years) with focal, international cartilage repair society grade III or IV articular cartilage defects of the knee joint were enroled at four centres across India from April 2015 to September 2015. Punch biopsy was conducted to harvest cartilage, from which chondrocytes were isolated and cultured, and the characterised chondrocytes were implanted into the cartilage defect. Key efficacy outcomes were assessed by quantitative changes in international knee documentation committee (IKDC), visual analogue scale (VAS) scores, and qualitative changes in magnetic resonance imaging at six months and four years from baseline. RESULTS: Of the14 patients enroled in the study, all patients completed the six month follow-up and 11 completed the four year follow-up. The IKDC score improved significantly from 32.84 ± 9.25 at baseline to 67.49 ± 13.03 at six months (mean difference [MD] 34.66 ± 13.00, p < 0.0001) and to 60.18 ± 10.33 at four years (MD 28.21 ± 15.14, p = 0.0001). The VAS score reduced from 72.00 ± 14.40 at baseline to 16.64 ± 17.03 at six months (MD 55.36 ± 24.50, p < 0.0001) and further to 12.72 ± 9.05 at four years (MD 62.09 ± 10.66, p < 0.0001). All patients showed improvement on MRI of the knee joint. No adverse events were reported. CONCLUSION: Autologous adult live cultured chondrocytes (CARTIGROW®) implantation showed good mid-term efficacy in patients with cartilage defects of the knee joint with no side-effects.

Mycoplasma pneumoniae co-infection with SARS-CoV-2: A case report.

We report co-infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and Mycoplasma pneumoniae in a patient with pneumonia in India. Atypical bacterial pathogens causing community-acquired pneumonia may share similar clinical presentations and radiographic features with SARS-CoV-2 making a thorough differential diagnosis essential. The co-infection of SARS-CoV-2 and M. pneumoniae is infrequently reported in the literature. Broader testing for common respiratory pathogens should be performed in severe COVID-19 cases to rule out other concurrent infections. Early identification of co-existing respiratory pathogens could provide pathogen-directed therapy, and can save patient lives during the ongoing COVID-19 outbreak.

Prevalence of low bone mineral density in inflammatory bowel disease and factors associated with it.

BACKGROUND: Patients with inflammatory bowel disease (IBD) have numerous risk factors for low bone mineral density (BMD). We aimed to study the prevalence of low BMD in IBD and the factors associated with it. METHODS: BMD was measured by radial quantitative ultrasound, and clinical and biochemical characteristics were compared in prospectively enrolled patients and healthy age and gender-matched controls. Chi-square test, t test for independent samples, analysis of variance (ANOVA), Mann-Whitney U test and Kruskal-Wallis H tests were used as appropriate for univariate analysis to compare the characteristics between patients with and without abnormal BMD. Binary logistic regression analysis was done to determine the factors associated with low BMD in IBD patients. RESULTS: One hundred and six patients (Crohn's disease [CD] = 35, ulcerative colitis [UC] = 71) and 55 controls were included. Low BMD was equally prevalent in CD, UC and controls (42.9%, 36.6%, 36.4% respectively, p = 0.791). Serum calcium and vitamin D were significantly lower in IBD patients compared to controls (p < 0.001 and p = 0.003, respectively) but not between patients with low and normal BMD. Older age (Odds ratio [OR] = 66.12 [9.299-470.243], p < 0.001), late onset of disease (OR = 4.795 [1.067-21.543], p = 0.041) and absence of steroid usage (OR = 0.272 [0.089-0.832], p = 0.022) were significantly associated with low BMD. CONCLUSIONS: The prevalence of low BMD in patients with IBD was similar to controls and this was associated with increasing age, late onset of disease, and absence of steroid usage. Judicious use of steroids can help preserve bone health in IBD.

Clinical and Structural Outcomes after Arthroscopic Repair of Medium- to Massive-Sized Delaminated and Nondelaminated Rotator Cuff Tears.

INTRODUCTION: Current evidence is controversial about the outcomes after the repair of the delaminated versus nondelaminated rotator cuff tears. The objective of this study was to evaluate the factors affecting delamination of the cuff and clinical and structural outcomes after en masse arthroscopic repair of delaminated versus nondelaminated cuff of varying sizes. MATERIALS AND METHODS: A total of 233 patients with full-thickness posterosuperior cuff tears were divided in two groups: Group 1: Delaminated tears (n = 131) and Group 2: Nondelaminated tears (n = 102) of medium, large, and massive sizes. Both groups were evaluated by clinical scores (Constant-Murley [CM], American shoulder and elbow score [ASES]) and ultrasonography (USG), at a minimum followup of 2 years. RESULTS: The mean followup was 45.47 months. There was a weak but statistically significant linear correlation (P = 0.02) between the increasing size of tear and delamination, whereas increasing age and duration of symptoms did not correlate with increasing tendency of delamination. Final followup USG analysis revealed that there was no significant difference (P = 0.55) between healing rates of Group 1 and Group 2. Further taking various tear sizes into account, USG revealed no significant difference between the healing rates of two groups. The mean overall final postoperative CM and ASES scores of two groups did not show any significant difference (CM; P = 0.36, ASES; P = 0.4). However, the clinical outcome was significantly better in the completely healed group as compared to partially healed or retear group. CONCLUSIONS: A weak linear correlation between delamination and increasing size of the tear was noted. Although overall structural and clinical outcome is no different between two groups, the clinical outcomes of completely healed tear are better than partially healed ones. LEVEL OF EVIDENCE: Level III, Retrospective comparative.

Does application of moderately concentrated platelet-rich plasma improve clinical and structural outcome after arthroscopic repair of medium-sized to large rotator cuff tear? A randomized controlled trial.

BACKGROUND: Platelet-rich plasma (PRP) has the potential to improve tendon-bone healing. The evidence is still controversial as to whether PRP application after repair of medium-sized to large cuff tears leads to superior structural and clinical outcome, especially after single-row repair. METHODS: In a randomized study, 102 patients (PRP group, 52 patients; control group, 50 patients) with medium-sized and large degenerative posterosuperior tears were included for arthroscopic repair with a minimum follow-up of 2 years. Patients were evaluated with clinical scores (visual analog scale score, Constant-Murley score, University of California-Los Angeles score, and American Shoulder and Elbow Surgeons score) and ultrasound to assess retear and vascularity pattern of the cuff. RESULTS: Visual analog scale scores were significantly lower in the PRP group than in controls at 1 month, 3 months, and 6 months but not later. Constant-Murley scores were significantly better in the PRP group compared with controls at 12 and 24 months, whereas University of California-Los Angeles scores were significantly higher in the PRP group at 6 and 12 months (P < .05). The American Shoulder and Elbow Surgeons score in both groups was comparable at all the times. At 24 months, retear in the PRP group (n = 2; 3.8%) was significantly lower than in the control group (n = 10; 20%; P = .01). The retear difference was significant only for large tears (PRP:control group, 1:6; P = .03). Doppler ultrasound examination showed significant vascularity in the PRP group repair site at 3 months postoperatively (P < .05) and in peribursal tissue until 12 months. CONCLUSION: Application of moderately concentrated PRP improves clinical and structural outcome in large cuff tears. PRP also enhances vascularity around the repair site in the early phase.

Nonfatal air embolism during shoulder arthroscopy.

An air embolism is a rare but potentially fatal complication of shoulder arthroscopy. In this article, we report the case of a patient who developed a nonfatal air embolism during shoulder arthroscopy for an acute bony Bankart lesion and a greater tuberosity avulsion fracture. The venous air embolism occurred immediately after the joint was insufflated with air for diagnostic air arthroscopy. The diagnosis was based on a drop in end-tidal carbon dioxide and blood pressure and presence of mill wheel (waterwheel) murmur over the right heart. Supportive treatment was initiated immediately. The patient recovered fully and had no further complications of air embolism. This patient's case emphasizes the importance of being aware that air embolisms can occur during shoulder arthroscopy performed for acute intra-articular fractures of the shoulder. Monitoring end tidal carbon dioxide can be very useful in early detection of air embolisms.

An intraarticular fibroma of the tendon sheath in the knee joint.

Fibromas that usually occur in the tendon sheaths of the wrist and hand are extremely rare in intra-articular locations. Only five such cases in the knee joint have been reported so far. This is a case report of an intra-articular fibroma of the tendon sheath of the knee joint arising adjacent to posterior cruciate ligament (PCL). Magnetic resonance imaging (MRI) revealed a well-defined intra-articular lesion in the region of the intercondylar notch of the femur behind the PCL. The mass was excised by arthrotomy. Histopathological study confirmed the diagnosis.

Ring meniscus mistaken for incomplete discoid meniscus: a case report and review of literature.

Ring meniscus is a known but rare abnormal variant of a meniscus. An incomplete discoid meniscus or an old bucket handle tear of a meniscus can be easily mistaken for a ring meniscus. In this case; during the first arthroscopy, the ring lateral meniscus was mistaken for an incomplete discoid lateral meniscus. On repeat arthroscopy, it was confirmed as ring lateral meniscus.
