RESUMO

Our study investigates vertebral fractures in individuals with distal radius fractures. Among 512 patients, 41.21% had vertebral fractures, predominantly in the lumbar spine. These findings highlight the importance of screening for vertebral fractures in this population, informing early intervention strategies to mitigate risks associated with osteoporosis. PURPOSE: This study's main goal was to look into the frequency, location, kind, and severity of asymptomatic vertebral fragility fractures (VFF) in people who had fractures of the fragility of the distal radius. Although VFF is frequently misdiagnosed, it is linked to higher mortality, morbidity, and hip fracture risk. The study also attempted to investigate the relationship between VFF and certain demographic and lifestyle factors, as well as FRAX data, in this patient population. METHODS: Between January, 2021, and January, 2022, individuals with low-energy distal radial fractures who presented to the emergency room of tertiary care hospital of Karachi, Pakistan, were the subject of a cross-sectional study and were 45 years of age or older except those who fitted the exclusion criteria (n = 208). The thoracic and/or lumbar spine was imaged using radiology, and information on demographics, way of life, and FRAX (Fracture Risk Assessment Tool) was gathered. Using the Genant semiquantitative approach, an impartial and blinded orthopaedist identified VF in the images and determined their severity. SPSS version 20 was used to analyse the data. RESULTS: Two hundred eleven (41.21%) of them were found to have radiographic VFF and only 12 (2.34%) of the 512 patients who were tested were getting osteoporotic therapy. The thoracic spine (32.7%), followed by the lumbar spine (43.12%), was the area most frequently afflicted. In 24.17% of the patients, multiple fractures of the thoracolumbar spine were found. The wedge form (54.5%), followed by biconcave (30.81%) and crush (14.7%), was the most prevalent VFF type. The majority of detected VFF were rated as having a 25-40% height loss (64.9%) then severe (> 40%) fractures (35.1%), according to the Genant grading method. Notably, there were no variations in smoking, drinking, BMI, or FRAX score between patients with and without VFF that were statistically significant. CONCLUSION: Based on our study's findings, it is clear that osteoporotic vertebral fragility fractures occur in almost half of individuals with distal radius fractures. The lumbar spine is notably the most affected region, predominantly with wedge fractures. Given the high prevalence of asymptomatic vertebral fragility fractures (VFF), proactive measures are necessary to mitigate associated risks. Prioritising comprehensive fall risk assessments for these patients and interventions to enhance bone mineral density and strength are crucial. Early identification of asymptomatic VFF enables timely intervention, optimising patient care and minimising the risk of complications in this vulnerable population.

RESUMO

PURPOSE OF REVIEW: The purpose of this review is to summarize the recent literature regarding regional anesthesia (RA) techniques and outcomes for total hip arthroplasty (THA) in the face of changing surgical techniques and perioperative considerations. RECENT FINDINGS: Based on large meta-analyses, peripheral nerve blocks are indicated for THA. Each block has its own risks and benefits and data for outcomes for particular techniques are limited. New surgical techniques, improved use of multimodal analgesia, and improved ultrasound guided regional anesthetics lead to better pain control for patients undergoing THA with less associated risks. Block selection continues to be influenced by provider comfort, surgical approach, patient anatomy, and postoperative goals. Head-to-head studies of particular nerve blocks are warranted.

RESUMO

This comprehensive review delves into the complex issue of plastic pollution, focusing on the emergence of biodegradable plastics (BDPs) as a potential alternative to traditional plastics. While BDPs seem promising, recent findings reveal that a large number of BDPs do not fully degrade in certain natural conditions, and they often break down into microplastics (MPs) even faster than conventional plastics. Surprisingly, research suggests that biodegradable microplastics (BDMPs) could have more significant and long-lasting effects than petroleum-based MPs in certain environments. Thus, it is crucial to carefully assess the ecological consequences of BDPs before widely adopting them commercially. This review thoroughly examines the formation of MPs from prominent BDPs, their impacts on the environment, and adsorption capacities. Additionally, it explores how BDMPs affect different species, such as plants and animals within a particular ecosystem. Overall, these discussions highlight potential ecological threats posed by BDMPs and emphasize the need for further scientific investigation before considering BDPs as a perfect solution to plastic pollution.

RESUMO

BACKGROUND: Hyperfunction of the muscles of the upper lip is considered as the most common cause of excessive gingival display (EGD). The aim of this study was to demonstrate the effectiveness of botulinum toxin (BT) injection as a conservative treatment for EGD due to muscular hyperfunction and to compare the outcome of 2 injection methods. MATERIAL AND METHODS: This study included 40 participants who were randomly assigned into 2 groups of 20 each, The first group received 2.5IU BT injection at 1 point per side (2-points group), while the second group received a total of 5 IU of BT at 2 points per side (4-points group). The outcome variables were the reduction in the central and lateral gingival display expressed as the difference between the pre- and post-injection measurements and the degree of satisfaction of the participants. The follow up visits were at 2- and 12-weeks postinjection. The study variables were statistically analyzed and probability values of <0.05 were considered significant. RESULTS: There was a significant improvement (P < 0.0001) in both groups throughout the follow up period, but the improvement achieved by 4-points group was significantly better than that of the 2-points group with respect to the gingival display and the degree of satisfaction (P < 0.0001). CONCLUSIONS: Botulinum toxin injection represents a safe and less invasive modality for treatment of EGD, the 4-points method results in better outcome in terms of clinical measurements and degree of satisfaction over the 2-points method.

RESUMO

Granulomatous mastitis (GM) is a rare, benign inflammatory disease of the breast with unknown etiology. There is no universally accepted treatment for GM. The aim of this study was to show our experience with surgical treatment of GM. A retrospective review was performed for 29 cases that were surgically treated at Salmaniya Medical Complex (SMC) in Bahrain between 2010 and 2017. All patients underwent surgical excision with debridement and removal of retroareolar ductal system. None of these patients experienced recurrence in the follow-up period. Complete surgical excision of the whole inflammatory mass is the treatment of choice.

RESUMO

BACKGROUND: Current measures of obesity do not accurately describe body composition. Using cross-sectional imaging, objective measures of musculature and adiposity are possible and may inform efforts to optimize liver transplantation outcomes. METHODS: Abdominal visceral fat area and psoas muscle cross-sectional area were measured on CT scans for 348 liver transplant recipients. After controlling for donor and recipient characteristics, survival analysis was performed using Cox regression. RESULTS: Visceral fat area was significantly associated with post-transplant mortality (p < 0.001; HR = 1.06 per 10 cm(2) , 95% CI: 1.04-1.09), as were positive hepatitis C status (p = 0.004; HR = 1.78, 95% CI: 1.21-2.61) and total psoas area (TPA) (p < 0.001; HR = 0.91 per cm(2) , 95% CI: 0.88-0.94). Among patients with smaller TPA, the patients with high visceral fat area had 71.8% one-yr survival compared to 81.8% for those with low visceral fat area (p = 0.15). At five yr, the smaller muscle patients with high visceral fat area had 36.9% survival compared to 58.2% for those with low visceral fat area (p = 0.023). CONCLUSIONS: Abdominal adiposity is associated with survival after liver transplantation, especially in patients with small trunk muscle size. When coupled with trunk musculature, abdominal adiposity offers direct characterization of body composition that can aid preoperative risk evaluation and inform transplant decision-making.

RESUMO

Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) is a recently described chronic inflammatory central nervous system disease. This case report describes a young female patient presenting with weakness in bilateral upper and lower limbs and tinnitus for 2 months. A neurological examination revealed signs of brainstem and cerebellar involvement. MRI brain showed characteristic features of CLIPPERS, with punctate and nodular enhancement in the pons and cerebellum. Differential diagnoses were systematically considered and excluded. The patient showed significant clinical and radiological improvement with steroid therapy. No clinical or radiological red flags occurred during the follow-up. This case underscores the critical role of integrating clinical and radiological findings to effectively diagnose and manage CLIPPERS. It emphasises the importance of ruling out alternative diagnoses through a thorough evaluation.

RESUMO

Objective: Staging workup and detection of distant metastases is important in newly diagnosed breast cancer in order to make treatment decisions and establish the prognosis. There is wide variation in current recommendations for staging investigations in breast cancer. Routine staging is performed for all patients in Bahrain because of lack of consistent guidelines. Optimization of the criteria for staging is important for identification of metastases, while minimizing harm and costs. The aim of this study was to evaluate factors associated with distant metastases in newly diagnosed patients with breast cancer, in order to establish local guidelines for proper selection of patients for systemic staging. Materials and Methods: Patients with newly diagnosed breast cancer at Salmaniya Medical Complex in Bahrain who underwent staging investigations between January 2016 and December 2022 were identified from a pathology database. Patients with previous history of cancer, synchronous tumors, bilateral breast cancer and ductal carcinoma in situ were excluded. Clinical, radiological and pathological data were retrospectively analyzed. Results: A total of 593 patients underwent staging computed tomography and bone scans or a PET scan. Distant metastases were identified in 20.7% of cases. M1 disease was significantly associated with multifocality/multicentricity, high grade tumors, hormone receptor-negative cancers, high Ki67 index, advanced tumor stage, node-positive disease, triple-negative breast cancer, use of PET scans and those who underwent neoadjuvant chemotherapy. Age was not associated with identification of distant metastases. Conclusion: The prevalence of distant metastases in this population of newly diagnosed patients with breast cancer was higher than previously reported. Routine staging of all patients at presentation was not indicated, especially for asymptomatic patients with early breast cancer. This study identified certain groups of patients with a higher risk of distant metastasis, in whom metastatic workup should be performed. These findings may allow for the development of a local guideline that addresses the question of which breast cancer patients need staging investigations for distant metastases.

RESUMO

INTRODUCTION: Within a large, statewide collaborative, significant improvement in surgical quality has been appreciated (9.0% reduction in morbidity for elective general and vascular surgery). Our group has not noted such quality improvement in the care of patients who had emergency operations. With this work, we aim to describe the scope of emergency surgical care within the Michigan Surgical Quality Collaborative, variations in outcomes among hospitals, and variations in adherence to evidence-based process measures. Overall, these data will form a basis for a broad-based quality improvement initiative within Michigan. METHODS: We report morbidity, mortality, and costs of emergency and elective general and vascular surgery cases (N = 190,826) within 34 hospitals participating in the Michigan Surgical Quality Collaborative from 2005 to 2010. Adjusted hospital-specific outcomes were calculated using a stepwise multivariable logistic regression model. Adjustment covariates included patient specific comorbidities and case complexity. Hospitals were also compared on the basis of their adherence to evidence-based process measures [measures at the patient level for each case-Surgical Care Improvement Project (SCIP)-1 and SCIP-2 compliance]. RESULTS: Emergency procedures account for approximately 11% of total cases, yet they represented 47% of mortalities and 28% of surgical complications. The complication-specific cost to payers was $126 million for emergency cases and $329 million for elective cases. Adjusted patient outcomes varied widely within Michigan Surgical Quality Collaborative hospitals; morbidity and mortality rates ranged from 16.3% to 33.9% and 4.0% to 12.4%, respectively. The variation among hospitals was not correlated with volume of emergency cases and case complexity. Hospital performance in emergency surgery was found to not depend on its share of emergent cases but rather was found to directly correlate with its performance in elective surgery. For emergency colectomies, there was a wide variation in compliance with SCIP-1 and SCIP-2 measures and overall compliance (42.0%) was markedly lower than that for elective colon surgery (81.7%). CONCLUSIONS: Emergency surgical procedures are an important target for future quality improvement efforts within Michigan. Future work will identify best practices within high-performing hospitals and disseminate these practices within the collaborative.

RESUMO

Despite recent improvements to current therapies and the emergence of novel agents to manage advanced non-small cell lung cancer (NSCLC), the patients' overall survival remains poor. Re-challenging with first-line chemotherapy upon relapse is common in the management of small cell lung cancer but is not well reported for advanced NSCLC. NSCLC relapse has been attributed to acquired drug resistance, but the repopulation of sensitive clones may also play a role, in which case re-challenge may be appropriate. Here, we report the results of re-challenge with gemcitabine plus carboplatin in 22 patients from a single institution who had previously received gemcitabine plus platinum in the first-line setting and had either partial response or a progression-free interval of longer than 6 months. In this retrospective study, the charts of patients who underwent second-line chemotherapy for NSCLC in our cancer center between January 2005 and April 2010 were reviewed. All the patients who received a combination of gemcitabine and carboplatin for re-challenge were included in the study. These patients were offered second-line treatment on confirmation of clear radiological disease progression. The overall response rate was 15% and disease control rate was 75%. The median survival time was 10.4 months, with 46% of patients alive at 1 year. These results suggest that re-challenge chemotherapy should be considered in selected patients with radiological partial response or a progression-free survival of longer than 6 months to the initial therapy.

RESUMO

Human health/socioeconomic development is closely correlated to environmental pollution, highlighting the need to monitor contaminants in the real environment with reliable devices such as biosensors. Recently, variety of biosensors gained high attention and employed as in-situ application, in real-time, and cost-effective analytical tools for healthy environment. For continuous environmental monitoring, it is necessary for portable, cost-effective, quick, and flexible biosensing devices. These benefits of the biosensor strategy are related to the Sustainable Development Goals (SDGs) established by the United Nations (UN), especially with reference to clean water and sources of energy. However, the relationship between SDGs and biosensor application for environmental monitoring is not well understood. In addition, some limitations and challenges might hinder the biosensor application on environmental monitoring. Herein, we reviewed the different types of biosensors, principle and applications, and their correlation with SDG 6, 12, 13, 14, and 15 as a reference for related authorities and administrators to consider. In this review, biosensors for different pollutants such as heavy metals and organics were documented. The present study highlights the application of biosensor for achieving SDGs. Current advantages and future research aspects are summarized in this paper.Abbreviations: ATP: Adenosine triphosphate; BOD: Biological oxygen demand; COD: Chemical oxygen demand; Cu-TCPP: Cu-porphyrin; DNA: Deoxyribonucleic acid; EDCs: Endocrine disrupting chemicals; EPA: U.S. Environmental Protection Agency; Fc-HPNs: Ferrocene (Fc)-based hollow polymeric nanospheres; Fe3O4@3D-GO: Fe3O4@three-dimensional graphene oxide; GC: Gas chromatography; GCE: Glassy carbon electrode; GFP: Green fluorescent protein; GHGs: Greenhouse gases; HPLC: High performance liquid chromatography; ICP-MS: Inductively coupled plasma mass spectrometry; ITO: Indium tin oxide; LAS: Linear alkylbenzene sulfonate; LIG: Laser-induced graphene; LOD: Limit of detection; ME: Magnetoelastic; MFC: Microbial fuel cell; MIP: Molecular imprinting polymers; MWCNT: Multi-walled carbon nanotube; MXC: Microbial electrochemical cell-based; NA: Nucleic acid; OBP: Odorant binding protein; OPs: Organophosphorus; PAHs: Polycyclic aromatic hydrocarbons; PBBs: Polybrominated biphenyls; PBDEs: Polybrominated diphenyl ethers; PCBs: Polychlorinated biphenyls; PGE: Polycrystalline gold electrode; photoMFC: photosynthetic MFC; POPs: Persistent organic pollutants; rGO: Reduced graphene oxide; RNA: Ribonucleic acid; SDGs: Sustainable Development Goals; SERS: Surface enhancement Raman spectrum; SPGE: Screen-printed gold electrode; SPR: Surface plasmon resonance; SWCNTs: single-walled carbon nanotubes; TCPP: Tetrakis (4-carboxyphenyl) porphyrin; TIRF: Total internal reflection fluorescence; TIRF: Total internal reflection fluorescence; TOL: Toluene-catabolic; TPHs: Total petroleum hydrocarbons; UN: United Nations; VOCs: Volatile organic compounds.

RESUMO

Composting with food waste was assessed for its efficacy in decontaminating Bisphenol A (BPA). In a BPA-treated compost pile, the initial concentration of BPA 847 mg kg-1 fell to 6.3 mg kg-1 (99% reduction) over a 45-day composting period. The biodegradation rate was at its highest when bacterial activity peaked in the mesophilic and thermophilic phases. The average rate of total biodegradation was 18.68 mg kg-1 day-1. Standard methods were used to assess physicochemical parameters of the compost matrix and gas chromatography combined with mass spectrometry (GC/MS) was used to identify BPA intermediates. Next-generation sequencing (NGS) was used to detect BPA degraders and the diverse bacterial communities involved in BPA decomposition. These communities were found consist of 12 phyla and 21 genera during the composting process and were most diversified during the maturation phase. Three dominant phyla, Firmicutes, Pseudomonadota, and Bacteroidetes, along with Lactobacillus, Proteus, Bacillus, and Pseudomonas were found to be the most responsible for BPA degradation. Different bacterial communities were found to be involved in the food waste compost biodegradation of BPA at different stages of the composting process. In conclusion, food waste composting can effectively remove BPA, resulting in a safe product. These findings might be used to expand bioremediation technologies to apply to a wide range of pollutants.

RESUMO

Objective: Sentinel lymph node biopsy (SLNB) is the standard of care for axillary staging in clinically node negative breast cancer. If predictive factors for sentinel lymph node (SLN) metastasis could be identified, it would allow selection of candidates for SLNB and omit axillary surgery in those with the lowest risk of axillary lymph node involvement. The aim of this study was to determine risk factors associated with SLN metastasis in breast cancer patients in Bahrain. Materials and Methods: Patients with clinically node-negative breast cancer who underwent SLNB at a single institution between 2016 and 2022 were identified from the pathology database. Patients who had failure of localization of SLN, those with bilateral cancers and those treated for a local recurrence were excluded. Results: A total of 160 breast cancer patients were retrospectively analyzed. Of these, 64.4% had a negative SLNB and 21.9% of all cases underwent axillary dissection. The following parameters emerged as predictors of SLN metastasis in univariate analysis: age; tumour grade; ER status; presence of lymphovascular invasion (LVI) and tumor size. On multivariate analysis, age was not independently associated with the incidence of SLN metastasis. Conclusion: This study showed that high tumour grades, presence of LVI and large tumour size were all risk factors related to axillary metastasis after SLNB in breast cancer. In the elderly, the incidence of SLN metastasis appeared to be relatively low, providing an opportunity to de-escalate axillary surgery in these patients. These findings may allow for the development of a nomogram to estimate the risk of SLN metastasis.

RESUMO

Anatomical variations of the brachial plexus are very common. Knowledge of the possible anatomical variations encountered in ultrasound imaging is crucial for the safe and effective practice of regional anesthesia. The interscalene block (ISB) targets the brachial plexus roots in the interscalene groove, between the anterior and middle scalene muscles (MSM), at the level of the sixth cervical vertebra. Blockade of the brachial plexus roots anesthetizes the shoulder region, making the ISB one of the preferred regional anesthesia options in shoulder surgeries. Abnormalities of the muscular structures surrounding the brachial plexus roots can pose a challenge while performing an ultrasound-guided ISB. We present a case of an unanticipated anatomical variation of the anterior scalene muscle (ASM) encountered on ultrasound imaging when performing an ISB. Our patient was found to have a small redundant ASM, which necessitated an alternative scanning approach and the use of a nerve stimulator to properly identify the brachial plexus roots. Based on our findings, we recommend placing the ultrasound probe parallel to the clavicle in the supraclavicular area and scanning in a cranial direction, tracing the brachial plexus back to the roots, and then confirming the needle placement by using a traditional nerve stimulator before local anesthetic deposition.

RESUMO

Cytoreduction surgery with hyperthermic intraperitoneal chemotherapy is a complex and painful procedure that can cause postoperative hypotension and coagulopathy. Epidural analgesia may worsen hypotension and is contraindicated in the setting of coagulopathy. While alternative regional techniques are being explored, the use of erector spinae plane blocks has not been reported. We present a case series of 6 patients who had erector spinae plane catheters for cytoreduction surgery with hyperthermic intraperitoneal chemotherapy. They remained stable intraoperatively and had adequate pain control postoperatively. Erector spinae plane catheters may be a suitable alternative for epidural analgesia for these patients.

RESUMO

This study developed and examined the application of bismuth sulfide doped on graphitic carbon nitride (Bi2S3@g-C3N4) in the degradation of NO under solar irradiation. Bi2S3@g-C3N4 was prepared through the calcination method. The morphological structure and chemical properties of the synthesized photocatalyst were analyzed before the degradation tests. After doping with Bi2S3@g-C3N4, the bandgap was reduced to 2.76 eV, which increased the absorption of solar light. As a result, the Bi2S3@g-C3N4 achieved higher NO degradation (55%) compared to pure Bi2S3 (35%) and g-C3N4 (45%). The trapping test revealed that the electrons were the primary species responsible for most of the NO degradation. The photocatalyst was stable under repeated solar irradiation, maintaining degradation efficiencies of 50% after five consecutive recycling tests. The present work offers strong evidence that Bi2S3@g-C3N4 is a stable and efficient catalyst for the photocatalytic oxidation of NO over solar irradiation.

RESUMO

We report a 61-year-old woman with primary right breast cancer and metastatic lymphadenopathy in the contralateral axilla. This case represents a clinical dilemma because primary breast cancer, occult contralateral breast cancer and extra-mammary primary lesion can all be the source of the contralateral axillary metastasis. The patient underwent bilateral modified radical mastectomy. Immunohistochemistry revealed that the right breast was positive for estrogen receptor (ER) and progesterone receptor (PR), but negative for human epidermal growth factor receptor-2 (HER2). In contrast, the right and left axillary lymph nodes were positive for ER, but negative for PR and HER2. There was no evidence of occult primary cancers or extra-mammary tumours.

RESUMO

Intussusception in adults is a rare condition. Unlike in children, it is often associated with a pathologic lesion that serves as a lead point. We report an unusual case of ileo-caecal intussusception due to lipoma. A 51-year-old male presented with symptoms and signs of intestinal obstruction. CT scan revealed bowel obstruction, resulting from ileo-caecal intussusception with the lead point being a lipoma of the terminal ileum. Ileocaecal resection with primary anastamosis was performed with histology confirming lipoma. Intussusception is not a common cause for intestinal obstruction in adults and is best diagnosed with CT scan. Surgical resection remains the definitive treatment in adult intussusception.

RESUMO

Although colonic volvulus is a relatively rare cause of large bowel obstruction, accounting for up to 5% of all cases of intestinal obstruction, transverse colon volvulus is extremely uncommon compared with volvulus of the sigmoid colon or caecum and is responsible for only 3% of all reported cases. We report an unusual case of spontaneous volvulus of the transverse colon in a young man with sickle cell disease who underwent resection with primary anastamosis. Having a high index of suspicion and early operative intervention allowed for this patient to have an uneventful postoperative course.

A 58-year-old female patient presented with left breast lump. Mammography and ultrasonography were performed, which reported lesions suspicious of malignancy in the left breast and axilla. Core biopsy of the lesions revealed invasive ductal carcinoma with axillary lymph node metastasis. Staging CT scan (thorax, abdomen and pelvis) identified a coexisting neoplasm in the ascending colon. Colonoscopy was performed and the tumour in the ascending colon was biopsied. Histopathological examination revealed adenocarcinoma. In the multidisciplinary team cancer meeting, it was decided to treat the breast cancer first and then the colon cancer, followed by adjuvant chemotherapy. In the first operation, left modified radical mastectomy was performed. Two weeks after her initial operation, the patient underwent laparoscopic right hemicolectomy. Postoperatively, the patient did not develop any complications and was referred to oncology for chemotherapy.
