RESUMEN

The urgent need to address global carbon emissions and promote sustainable energy solutions has led to a growing interest in carbon dioxide (CO2) conversion technologies. Among these, the transformation of CO2 into methanol (MeOH) has gained prominence as an effective mitigation strategy. This review paper provides a comprehensive exploration of recent advances and applications in the direct utilization of CO2 for the synthesis of MeOH, encompassing various aspects from catalysts to market analysis, environmental impact, and future prospects. We begin by introducing the current state of CO2 mitigation strategies, highlighting the significance of carbon recycling through MeOH production. The paper delves into the chemistry and technology behind the conversion of CO2 into MeOH, encompassing key themes such as feedstock selection, material and energy supply, and the various conversion processes, including chemical, electrochemical, photochemical, and photoelectrochemical pathways. An in-depth analysis of heterogeneous and homogeneous catalysts for MeOH synthesis is provided, shedding light on the advantages and drawbacks of each. Furthermore, we explore diverse routes for CO2 hydrogenation into MeOH, emphasizing the technological advances and production processes associated with this sustainable transformation. As MeOH holds a pivotal role in a wide range of chemical applications and emerges as a promising transportation fuel, the paper explores its various chemical uses, transportation, storage, and distribution, as well as the evolving MeOH market. The environmental and energy implications of CO2 conversion to MeOH are discussed, including a thermodynamic analysis of the process and cost and energy evaluations for large-scale catalytic hydrogenation.

RESUMEN

Tuberculosis being endemic in country like India can affect any organ though pulmonary tuberculosis is rampant and extrapulmonary is rare. Tuberculosis affecting parotid gland is a rare occurrence, usually unilateral. However, Mycobacterium tuberculosis causing cold abscess in bilateral parotid glands is even rarer. Here, we present a case of a young female presented with bilateral slow-growing swelling in the parotid region with evening raise of temperature for two months. On clinical examination, no signs of inflammation were seen. Ultrasonography showed thick-walled hypoechoic collection with septae and internal echoes within involving both superficial and deep lobes of the parotid gland. Fine-needle aspiration cytology (FNAC) suggested a caseating granuloma and acid fast bacilli were detected on ZN staining, thereby confirming the diagnosis of cold abscess. She was put on antitubercular drugs and there was a drastic reduction in the size of swelling.

RESUMEN

Stroke, a neurological disorder, has emerged as a formidable health challenge in India, with its incidence on the rise. Increased risk factors, which also correlate with economic prosperity, are linked to this rise, including hypertension, diabetes, obesity, sedentary lifestyle, and alcohol intake. Particularly worrisome is the impact on young adults, a pivotal segment of India's workforce. Stroke encompasses various clinical subtypes and cerebrovascular disorders (CVDs), contributing to its multifaceted nature. Globally, stroke's escalating burden is concerning, affecting developing nations. To combat this trend effectively and advance prevention and treatment strategies, comprehensive and robust data on stroke prevalence and impact are urgently required. In India, these encompass individuals with elevated BMIs, and those afflicted by hypertension, diabetes, or a familial history of stroke. Disparities in stroke incidence and prevalence manifest across India, with differences in urban and rural settings, gender-based variations, and regional disparities. Early detection, dietary changes, effective risk factor management, and equitable access to stroke care are required to address this issue. Government initiatives, like the National Programme for Prevention and Control of Cancer, Diabetes, Cardiovascular Diseases, and Stroke (NPCDCS) 2019, provide guidelines, but effective implementation and awareness campaigns are vital. Overcoming barriers to stroke care, especially in rural areas, calls for improved infrastructure, awareness campaigns, and support systems. Data standardization and comprehensive population studies are pivotal for informed public health policies.

RESUMEN

Intraosseous hemangiomas are uncommon and account to less than 1% of all osseous tumors. Vertebral body and skull are the most common sites involved. However involvement of facial bones is rare with zygoma being even rarer site. Due to its rarity it creates diagnostic dilemma clinically and radiologically. Its vascular nature carries the risk of intraoperative bleeding hence an accurate preoperative diagnosis with arterial embolization helps to avoid the dire consequences. Fine needle aspiration cytology along with radiological correlation is extremely helpful in such cases. We report such rare case in forty eight years female patient with brief review of literature.

RESUMEN

Background: A specific magnesium level is essential to be maintained to ensure appropriate neuromuscular excitability and cardiac function; an increase or decrease in its levels usually leads to critical abnormality. Hypomagnesemia in critically ill patients has many potential ramifications and is found to be an important factor in hindering their recovery. Thus, the study aimed to assess the serum magnesium levels in critically ill participants and explore its effect on their condition. Methods: A prospective observational study was conducted for 21 months, from February 2019 to October 2020, among all critically ill participants admitted to the medical intensive care unit (ICU) of a tertiary care hospital. The Acute Physiology and Chronic Health Evaluation II score questionnaire was used to determine the severity of their condition and blood samples were collected within 24 h of their ICU admission for analysis. Results: One hundred participants were enrolled, of which 40% were between the age group of 46 and 65 years and 71% were males. Among all participants with hypomagnesemia, 52% were diabetic, 19% had a history of alcohol use disorder, and 27% had normal calcium and potassium levels. Hypomagnesemia significantly correlated with a longer duration of ICU stay among participants. Conclusion: A significant correlation was observed between hypomagnesemia and increased ICU length of stay and mortality but not the duration of mechanical ventilation. Monitoring and appropriate supplementation of serum magnesium is recommended to limit further comorbidity and mortality in the critical care setting.

RESUMEN

Introduction: Anaplastic large cell lymphoma (ALCL), which makes up only 2-5% of instances of NHL, is a rare and aggressive form of the disease. Anaplastic Lymphoma Kinase (ALK)-positive ALCL is a variant of the illness that is identified by the presence of an ALK gene fusion. The disease is most commonly confined to the nodes, but extranodal spread has been reported. Skin and soft tissue are the most frequently identified locations for extranodal involvement, while joints are extremely rare. We describe a rare case of ALCL affecting the knee joint that is ALK -positive. Case Report: A 51-year-old female presented with pain in her right knee. It was diagnosed as synovitis and treated accordingly. The symptoms did not relieve and a magnetic resonance imaging (MRI) scan was performed that indicated a meniscus tear. She was treated for it; however, the symptoms worsened. She underwent two more scans (1 MRI and 1 PET) that indicated an enhancing polypoidal mass in the knee joint, and two arthroscopic procedures. The histopathology report indicated an ALK-positive ALCL. She was treated with Brentuximab vedotin + CHP followed by involved-site radiotherapy to the postoperative region with margins. The patient has had a complete clinical and pathological response which was assessed after 1 year from the start of the treatment. Conclusion: This is the first instance of primary ALK-positive ALCL affecting the knee joint that has been documented, to the best of our knowledge. The case emphasizes the significance of taking ALCL into account when determining the differential diagnosis of knee joint tumors as well as the requirement for a thorough assessment of extranodal involvement.

RESUMEN

PURPOSE: Very few studies have demonstrated the rituximab biosimilarity in terms of efficacy, safety, pharmacokinetics, pharmacodynamics, and immunogenicity in patients with diffuse large B-cell lymphoma (DLBCL) in India. Therefore, we compared the efficacy, safety, pharmacokinetic, pharmacodynamic, and immunogenicity of our biosimilar rituximab with the reference rituximab (Ristova, Roche products [India] Pvt. Ltd) in patients with DLBCL in India. METHODS: A phase 3, randomized, assessor-blind, parallel-group, two-arm study was conducted across 28 sites in India. A total of 153 newly diagnosed DLBCL patients were randomized to receive either biosimilar rituximab or reference rituximab. The study drugs were administered at a dose of 375 mg/m2 by intravenous infusion every 3 weeks for six cycles. The primary end point was objective response rate (ORR) at the end of Cycle 6. Secondary end points included: pharmacokinetic, pharmacodynamics, immunogenicity, and safety assessment. RESULTS: The ORR at the end of Cycle 6 was 82.14% in the biosimilar rituximab and 85.71% in the reference rituximab group. The risk difference (90% CIs) was - 3.57 (- 14.80, 7.66). It met the non-inferiority margin of - 20%. The pharmacokinetic and pharmacodynamic parameters were comparable between the two treatment groups. The incidence rate of immunogenicity was very low and similar in both the treatment groups. The safety profile of both the treatments was comparable with no major difference in terms of nature, frequency and severity of TEAEs. CONCLUSION: The study demonstrated the biosimilarity between the biosimilar rituximab and the reference rituximab. Our biosimilar rituximab could add to the cost-effective treatment alternatives for patients with DLBCL in India.

RESUMEN

Hyperglycemia is reported to predict worse outcome in patients with stroke, including intracerebral hemorrhage (ICH). In 83 consecutive cases of ICH at a tertiary stroke center, hyperglycemia (serum glucose >7 mmol/L) compared to normoglycemia at presentation was associated with higher rates of in-hospital mortality (51.2% vs. 26.2%, OR 2.3, CI 1.2-7.6, p = 0.02). The association with in-hospital mortality withstood adjustment for age, ICH volume, intraventricular hemorrhage, and infratentorial ICH location, but not baseline Glasgow Coma Scale. Acute hyperglycemia is associated with in-hospital mortality in spontaneous ICH patients, though this may be an indirect, rather than a causal relationship.

RESUMEN

Introduction: The rising demographic trend towards elderly population and increased incidence of osteosynthesis of proximal femur fractures are associated with increased recurrent falls and rise in incidence of peri- implant fractures. Case Report: Here, we present a difficult case of a peri-implant femur shaft fracture in a 55-year-old male, with stuck short proximal femur nail (PFN) removal followed by long distal femur plating with bone grafting showing good fracture union at 1 year with satisfactory functional outcome. Conclusion: Peri- implant femur fractures are quite rare and more commonly occur in elderly. Among all treatment modalities for intertrochanteric femur fracture fixation, the literature shows short PFN having highest comparative risk for peri-implant fractures. Implant removal followed by locking plates for long spiral fractures provides a stable, anatomical, and reliable fixation. Bone grafting augments bony union, especially in cases of bone defects .

RESUMEN

Context: Population-based seroepidemiological studies are recommended to measure the extent of spread of coronavirus disease of 2019 (COVID-19) infection in an area. The present seroprevalence survey was planned with the aim to estimate the cumulative burden of the COVID-19 disease in the Pimpri Chinchwad corporation area. Aims: To estimate the cumulative burden of the COVID-19 disease in the Pimpri Chinchwad corporation area. Settings and Design: The study was carried out in Pimpri Chinchwad Municipal Corporation (PCMC) city area. It was a descriptive cross-sectional survey. Materials and Methods: A population-based seroprevalence study for immunoglobulin G (IgG) antibodies for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) was carried out among 10082 residents in the age group of 6 years and above selected by cluster random sampling. Thirty-five clusters were in slums, 45 clusters in tenements and 120 clusters from housing societies. The fieldwork for the collection of samples was carried out from 16 June to 17 June 2021. For antibody testing, a kit from Abbott (SARS-CoV-2 IgG) was used which employs chemiluminescent microparticle immunoassay (CMIA) technology. Statistical Analysis Used: Frequency analysis was done for sociodemographic variables, the cumulative incidence of COVID-19, age-stratified infection rate, risk factors and COVID symptomatic versus asymptomatic cases. Chi-square test of association was applied to test the association between seropositivity and sociodemographic and clinical profile of participants. Results: The overall seropositivity for IgG antibodies was 81.34%. Those living in the Gaothan area (tenements) had a positivity rate of 84.5%. The age group between 45 and 60 years had a seropositivity of 91%. Conclusions: The study indicates that a considerable proportion of the population had encountered the novel coronavirus approaching herd immunity.

RESUMEN

Harlequin ichthyosis (HI) is the most severe type of congenital ichthyosis. It is extremely rare with very few cases reported in India. It is inherited in an autosomal recessive fashion. The importance of antenatal diagnosis by ultrasonography, DNA-based molecular studies on chorionic villus sampling, and amniocentesis has been emphasized. We report a new case of HI in an infant, diagnosed postnatally by correlation of clinical and histopathological features on skin biopsy. The infant succumbed on the second day of birth despite intensive supportive care. A short review of the literature regarding the condition is also presented.

RESUMEN

The world's population explosion creates a need for natural resources for energy, which will become a significant contributor to global climate change. As we all know, carbon dioxide (CO2) is one of the most critical elements of the global greenhouse gas effect. CO2 capture and storage innovations have piqued researchers' attention in recent decades. Compared to other methods, membrane separation has some positive performance in CO2 capture. CO2 capture with membrane separation using enhanced ionic liquids (ILs) is described in this review. ILs have made an appearance in CO2 capture work as the potential additive, and companies and academics have been interested in CO2 separation for the past two decades. This article comprehensively analyzes the current modern approach in ILs and IL-based membranes for gas separation processes. Based on the latest literature and performance data, this work provides a complete compressive examination of types of ILs and IL-supported membrane performances. ILs for CO2 capture were also explored, and IL-based membranes for different ILs were also studied. This study emphasizes the supremacy of novel ILs for CO2 capture in membrane separation.

RESUMEN

Background and aims: The utility of proposed non-contrast computed tomography (NCCT) markers for the prediction of hematoma expansion in patients with antithrombotic-related spontaneous intracerebral hemorrhage (ICH) is limited. Additionally, there is significant overlap between different suggested ICH shape and density markers. Methods: We assessed the prognostic yield for hematoma expansion of a combined score incorporating features of ICH shape irregularity (satellite sign and/or Barras score ≥ 3), heterogeneous ICH density (swirl sign and/or Barras score ≥ 3) on baseline NCCT and timing from ICH onset to NCCT. Results: We evaluated data from 79 patients with antithrombotic-related spontaneous ICH (32% with hematoma expansion). Swirl (84% vs. 39%) and satellite signs (20% vs. 7%) on baseline NCCT were significantly more prevalent (p < 0.001) in patients with hematoma expansion. Patients with hematoma expansion had more irregular and heterogeneous bleeds on baseline NCCT scans, as quantified by higher (p < 0.001) Barras shape (4 (4−5) vs. 3 (2−4)) and density scores (4 (3−5) vs. 2 (1−3)), respectively. The overall diagnostic yield of the combined score (area under the curve: 0.86, 95%CI: 0.78−0.94) significantly outperformed (p < 0.001) the diagnostic yield of each individual marker. Scores of 4 or 5 in the combined score were associated with a sensitivity of 60.0%, specificity of 90.7%, overall diagnostic accuracy of 81.0%, positive likelihood ratio (LR) of 6.48, negative LR of 0.44, positive predictive value (PV) of 0.76 and negative PV of 0.83. Conclusion: Combined NCCT marker assessment seems to increase the prognostic accuracy for hematoma expansion in antithrombotic-related spontaneous ICH patients.

RESUMEN

INTRODUCTION: Osteoid osteoma is a benign tumor of bones involving mainly the tubular bones and rarely axial skeletons. The patient mainly complains of night pain in the affected region or the joint nearby. Pain always subsides with analgesics and gradually increased over the period of time. It is mostly missed on the plain radiograph so magnetic resonance imaging or computed tomography (CT) scan are preferred for accurate and early diagnosis of the tumor. CASE REPORT: A 20-year-old male presented with pain in the left hip region which was gradually increased over the period of 6 months and was experiencing pain more in the night, used to relieve on medications. CT scan of the left hip showed the presence of osteoid osteoma of 0.5 cm diameter, which was managed with radiofrequency ablation. Moreover, the patient had pain relief immediately after the procedure. At present 1-year follow-up, the patient is symptomless with no recurrence. CONCLUSION: The neck of femur osteoid osteomas is best managed with radiofrequency ablation as it causes less morbidity to the patient and helps in early return to normal activities with fewer complications as compared to open procedures.

RESUMEN

Introduction We document our data on the course of the coronavirus disease 2019 (COVID-19) infection in cancer patients in an attempt to help optimize their management in India and globally. Material and Methods Between February 2020 and January 2021, participating oncologists from Pune (members of the Oncology Group of Pune) documented effect of COVID-19 infection in their cancer patients. Binomial logistic regression analysis as well as correlation analysis was done using Pearson Chi-square test to determine significance of clinical factors. Results A total of 29 oncologists from 20 hospitals contributed their data involving 147 cancer patients who developed COVID-19 infections. COVID-19 infection resulted in higher deaths (likelihood ratio of 4.4) amongst patients with hematological malignancies (12/44 = 27.2%) as compared with those with solid tumors (13/90 = 14.4%, p = 0.030). Patients with uncontrolled or progressive cancer (11/34 = 32.4%) when they got infected with COVID-19 had higher mortality as compared with patients whose cancer was under control (14/113 = 12.4%; p = 0.020). Complication of thromboembolic episodes (seen in eight patients; 5.4% cases) was associated with higher risk (25.6 times) of death (five-eighths; 62.5%) as compared with those who did not develop it (20/139;14.4%; p <0.001). Discussion Patients with cancer should be advised to take strict precautions to reduce the risk of being infected with COVID-19. They should also be given priority for COVID-19 vaccination. If infected with COVID-19, patients with hematological malignancy and uncontrolled cancer are at higher risk of morbidity and mortality. When they are being treated (OPD or inpatient basis), additional precautions are necessary to ensure their exposure to potential COVID-19 virus is minimized. If they get infected with COVID-19, they should be given aggressive treatment to prevent complications, especially thromboembolic episodes. If they develop any thromboembolic complication, their risk of dying are significantly higher, and management should be modified accordingly.

RESUMEN

INTRODUCTION: Synovial chondromatosis is a rare, benign disorder of the synovium, which leads to loose body formation due to metaplastic transformation. It presents as multiple cartilaginous bodies in the synovial joints, bursae and in tendon sheaths. The diagnosis often delayed in hip involvement due to insidious onset of symptoms. Surgical management is essential to manage synovial chondromatosis, which includes hip dislocation and debridement, arthroscopic removal or using arthrotomy. CASE REPORT: A 20-year-old male patient presented with complaints of pain in the left hip since 1 year and difficulty in walking for 6 months. On examination, the patient had mild tenderness over the left hip with the restriction of joint movements. He had flexion deformity of 30°, adduction and external rotation deformity of 10 and 15°, respectively. X-ray of the pelvis with both hips anteroposterior and left hip lateral view revealed calcified nodular mass over superior, inferior part of the femoral head, and anterior part of the neck with decreased joint space. As the patient was disabled with pain, stiffness especially restricted flexion and abduction and difficulty in daily routine activities, we planned for surgical excision of the loose bodies. Using lateral approach to the hip, intra-articular loose bodies were removed through arthrotomy without hip dislocation. At present 2-year follow-up, the patient is having full hip range of motion with no difficulty in squatting, sitting cross-legged, and radiological examination showed no evidence of recurrence. The patient is fully satisfied with the chosen treatment and participating in running and other sports. CONCLUSION: Although hip synovial chondromatosis are rare, early surgical intervention with complete removal of loose bodies, joint distraction for 6 weeks to allow healing, and early initiation of hip physiotherapy helps in getting better outcome even in patients with early stages of hip arthritis. The early surgical intervention also prevents the progression of the joint degeneration, which in turn helps in postponing replacement surgeries in young patients. Satisfactory outcomes can be achieved by salvaging the natural hip joint.

RESUMEN

Tumor-stroma interactions are important determinants for the disease course in cancer. While stromal influence has been known to often play a tumor-promoting role, incomplete mechanistic insight into this phenomenon has prevented its therapeutic targeting. Stromal fibroblasts can be activated by tumor cells to differentiate into cancer-associated fibroblasts (CAFs), that exhibit the traits of myofibroblasts, and in turn, they increase cancer aggressiveness. Here, we report the crosstalk between the cancer cells and stromal fibroblasts that leads to tumor progression. The process is initiated by secretion of a chemokine like protein, osteopontin (OPN) from the cancer cells that differentiates the fibroblasts to myofibroblasts. Tumor-derived OPN achieves this transition by engaging CD44 and αvß3 integrins on the fibroblast surface, which mediates signaling via Akt and ERK to induce Twist1-dependent gene expression. The OPN-driven CAFs then secrete CXCL12, which in turn triggers epithelial to mesenchymal transition (EMT) in the tumor cells. OPN, produced by the cancer cells, and CXCL12, secreted by activated fibroblasts, are necessary and sufficient to perpetuate the crosstalk. Knocking out OPN in carcinogen-induced mammary tumors or knocking down OPN in cancer cells and fibroblast co-implanted xenografts abrogates myofibroblast differentiation, Twist1, and CXCL12 expression. OPN expression is correlated with CAF-specific gene signature as shown by breast tumor tissue microarray consisting of 100 patient specimens. Bioinformatics analyses have confirmed that the expression of OPN is significantly correlated with the expression of myofibroblast-specific markers as demonstrated in human breast carcinoma dataset of 2509 patients. Our findings describe OPN and CXCL12 act as compelling targets to curb the tumor-promoting features of the stromal components and further suggested that OPN-regulated CXCL12 network might act as potential therapeutic target for the management of CAF-mediated breast cancer progression.

RESUMEN

Introduction: Finger dislocations account for 5% of upper extremity injuries. Metacarpophalangeal (MCP) joint/Kaplan dislocations post-trauma are of rare occurrence. An MCP joint dislocation is considered simple when it can be managed by closed reduction and considered complex when open reduction is necessary. Case Report: Here, we present a rare case of dorsal Kaplan dislocation of left second MCP joint in an 11 years old male child, which was managed by open dorsal approach with stable reducion and good functional outcome. Conclusion: We experienced closed reduction should not be tried in cases of complex dorsal dislocations. The dorsal approach of complex MCP dislocation is found to be safe and simple even in hands of inexperienced surgeons which may or may not need division of deep transverse ligament.

RESUMEN

Eyelid metastases are relatively rare, and they can occasionally lead the way to an unknown primary malignancy elsewhere. The authors report a case of 65-year-old diabetic gentleman with a right-sided eyelid lesion that was present for 1 month and turned out to be a presenting sign of a previously undiagnosed pancreatic adenocarcinoma. The eyelid mass had been treated elsewhere for 2 weeks for a presumed infectious lesion, using systemic antibiotics and was then referred to us in view of no response. The right-sided lesion involving the subbrow and eyelid area was tender and showed surface ulceration, as well as induration with scabbing. An incision biopsy of the mass was performed followed by computed tomography imaging. Histopathologic findings were suggestive of adenocarcinoma of a probable secondary origin. A whole-body positron emission tomography (PET) scan along with raised serum tumor markers (carcinoembryonic antigen 125 [CEA 125] and carbohydrate antigen 19-9 [CA-19-9]) was helpful in diagnosing a stage IV probable primary carcinoma of the pancreas, with metastasis to paraaortic nodes, liver, lungs, and eyelid. After a detailed systemic work-up, the patient was put on systemic chemotherapy with carboplatin and capacitabane. He responded well to the treatment. At a follow up of 12 months, upon clinical examination and PET imaging, he showed a complete resolution of eyelid, lung, and liver disease and a near-complete resolution of the pancreatic lesion. This case delineates the role of a prompt biopsy and histopathologic evaluation of an atypical eyelid mass in diagnosing asymptomatic primary malignancy.

RESUMEN

BACKGROUND AND AIM: Luteolin belongs to flavone group of flavonoids, present in many plants with potent antioxidant, anti-inflammatory and anti-proliferative effects. The objective of present study was to investigate protective effect of luteolin on injury induced inflammation via Monosodium urate (MSU) crystals induced and Acetaminophen (AMP) induced liver injury in rats. EXPERIMENTAL PROCEDURE: Protective effect of luteolin was observed by measurement of rat paw edema, lysosomal enzymes, antioxidants status and cytokine level. Measurement of uric acid level and neutrophil infiltration were done in AMP induced liver injury in rats. Luteolin was tested at 30 and 50 mg/kg doses and compare with colchicine. RESULTS AND CONCLUSION: Luteolin significantly decreases paw edema in dose dependent manner compare to control group in MSU crystal-induced rats. Luteolin (50 mg/kg) was showed significant decrease in serum level of oxidative and lysosomal enzymes, proinflammatory cytokines i.e. tumor necrosis factor (TNF)-α (39.28 ±â€¯3.17), interleukin (IL)-1ß (12.07 ±â€¯1.24), and IL-6 (24.72 ±â€¯2.52) in MSU crystal-induced rats. In AMP induced liver injury, tissue uric acid level and myeloperoxidase were decreased significantly after treatment with luteolin as well as N-acetylcysteine. Serum level of liver enzymes was significantly reduced after treatment with luteolin. Histological observation of ankle joints and liver was support to protective effect of luteolin at both doses. In conclusion, luteolin showed anti-inflammatory effect through restoration of cytokine level, lysosomal enzymes level and antioxidants status. The reduction of liver tissue uric acid content may be one of the mechanisms for protective effect of luteolin. It can contribute to reduce injury induced inflammation.
