RESUMEN

Vernonia is a woody shrub of the family Asteraceae. Over 1500 species are distributed in tropical and subtropical regions of Africa and Asia. There are more than 54 species known to possess similar morphological features with the characteristic bitter taste. The pharmacological properties of different parts like seeds, leaves, and roots are well documented in folk medicine. They are rich in biologically active constituents such as alkaloids, phenolics, flavonoids, terpenoids, steroid tannins, and carotenoids having broad therapeutic activities like antiinflammatory, hypoglycemic, hyperlipidemia, antimicrobial, antitumor, antioxidative, antiproliferative, antihypertensive, hepatoprotective, etc. The present study summarizes and discusses the phytochemical profile, pharmacological properties, and toxicological effects of the Vernonia plant.

RESUMEN

Sepsis is one of the deadliest disorders in the new century due to specific limitations in early and differential diagnosis. Moreover, antimicrobial resistance (AMR) is becoming the dominant threat to human health globally. The only way to encounter the spread and emergence of AMR is through the active detection and identification of the pathogen along with the quantification of resistance. For better management of such disease, there is an essential requirement to approach many suitable diagnostic techniques for the proper administration of antibiotics and elimination of these infectious diseases. The current method employed for the diagnosis of sepsis relies on the conventional culture of blood suspected infection. However, this method is more time consuming and generates results that are false negative in the case of antibiotic pretreated samples as well as slow-growing microbes. In comparison to the conventional method, modern methods are capable of analyzing blood samples, obtaining accurate results from the suspicious patient of sepsis, and giving all the necessary information to identify the pathogens as well as AMR in a short period. The present review is intended to highlight the culture shift from conventional to modern and advanced technologies including their limitations for the proper and prompt diagnosing of bloodstream infections and AMR detection.

RESUMEN

PURPOSE OF REVIEW: Approximately 36-57% of cases of pneumonia are associated with a parapneumonic effusion (PPE). It begins as sterile effusion, which can quickly evolve to a fibrinopurulent stage with evidence of infection called complicated parapneumonic effusions (CPPE). Marked fibrinous organization then follows. This study focuses on literature synthesis on management of CPPE. RECENT FINDINGS: Ultrasound has become an indispensable tool in the identification and treatment of CPPE. Prompt antibiotic administration remains the universal standard of care. Decision to drain the fluid is based on fluid staging, characterization and assessment of risk of poor outcomes vs. risk of complications. There is growing evidence to support use of intrapleural fibrinolytic therapy (IPFT) in case of loculated effusions. Newer areas of research include antibodies against plasminogen activator inhibitors and stratification scores that can identify patients at an increased risk. Lastly, timing of surgical referral is an important area under study. SUMMARY: Evolution of medical therapy over recent years has increased treatment success rates. Use of IPFT in conjunction to thoracostomy is now the standard of care for loculated effusions. Understanding available therapeutic options, both medical and interventional, can ensure evidence-based practice and improve patient-centred outcomes.

RESUMEN

India is the second largest consumer and producer of fruits globally. It leads to ample solid waste per year from fruit processing industries that have been proven hazardous to the surroundings. Punica granatum (Pomegranate) belongs to the Lythraceae subfamily Punicoideae, which exhibits immense nutritional properties and delicious flavoring components. The weight of this fruit mainly consists of peel, i.e., 50%, followed by 40% of arils and 10% of seeds. Thus, the major byproduct is a peel that holds many valuable bioactive compounds in higher concentrations viz saponins, carotenoids, steroids, polyphenols, quercetin derivatives, caffeic acid, phenolic acids, flavonoids, ellagitannins, p-coumaric acid, chlorogenic acid, quinic acid, anthocyanidins, triterpenoids, glycosides, tannins, and many more. Consequently, it results in wide-ranging therapeutic applications, including antioxidative, anti-microbial, antihypertensive, anti-carcinogenic, anti-genotoxic, anti-inflammatory, glucoregulation, cardio-protective, hepato-protective and nephroprotective effects along with prebiotic potential. Considering their nutritional and therapeutic aspects, these peels can be used for many purposes rather than being disposed of. With a value-added approach, it is utilized in many food and non-food sectors. So, this review aims to explore the therapeutic potential of P. granatum peel and enlighten its diverse applications in the food industry.

RESUMEN

CASE PRESENTATION: A 62-year-old White man with a history of orthotopic liver transplantation 16 years ago for alcoholic liver cirrhosis on chronic immunosuppression and recurrent decompensated cirrhosis of his graft liver complicated by ascites, hepatic encephalopathy, and esophageal varices presented to the hospital with altered mental status. Over the last few weeks, he had reduced frequency of bowel movements and subsequently developed altered sensorium 3 days before presentation. On arrival to the hospital, he was disoriented and had asterixis consistent with hepatic encephalopathy. He was not in respiratory distress, he was saturating well on room air, and his lungs were clear to auscultation bilaterally. Plain chest radiograph showed multiple ill-defined bilateral airspace opacities. A CT scan of the abdomen and pelvis done on admission incidentally showed bilateral pulmonary nodules with surrounding ground-glass halo in the lower lung zones. Given these findings, a dedicated CT scan of his chest was performed that showed numerous bilateral randomly distributed nodular airspace opacities, many with a central solid component and surrounding ground-glass halo. Antifungal therapy was initiated empirically. Serum aspergillus antigen and 1,3 beta D-glucan were negative. He subsequently underwent a bronchoscopy with BAL and transbronchial biopsy. BAL fluid was negative for bacterial, fungal, and acid-fast bacilli cultures. Pathology from the transbronchial biopsy showed atypical epithelioid cells in intravascular spaces.

RESUMEN

Previous reports from our lab have documented dysregulated host inflammatory reactions in response to bacterial infections in sepsis. Both Gram-negative bacteria (GNB) and Gram-positive bacteria (GPB) play a significant role in the development and progression of sepsis by releasing several virulence factors. During sepsis, host cells produce a range of inflammatory responses including inducible nitric oxide synthase (iNOS) expression, nitrite generation, neutrophil extracellular traps (NETs) release, and pro-inflammatory cytokines production. The current study was conducted to discern the differences in host inflammatory reactions in response to both Escherichia coli and Staphylococcus aureus along with the organ dysfunction parameters in patients of sepsis. We examined 60 ICU sepsis patients identified based on the Acute Physiology and Chronic Health Evaluation II (APACHE II) and Sequential Organ Failure Assessment (SOFA II) scores. Pathogen identification was carried out using culture-based methods and gene-specific primers by real-time polymerase chain reaction (RT-PCR). Samples of blood from healthy volunteers were spiked with E. coli (GNB) and S. aureus (GPB). The incidence of NETs formation, iNOS expression, total nitrite content, and pro-inflammatory cytokine level was estimated. Prevalence of E. coli, A. baumannii (both GNB), S. aureus, and Enterococcus faecalis (both GPB) was found in sepsis patients. Augmented levels of inflammatory mediators including iNOS expression, total nitrite, the incidence of NETs, and proinflammatory cytokines, during spiking, were found in response to S. aureus infections in comparison with E. coli infections. These inflammatory mediators were found to be positively correlated with organ dysfunction in both GN and GP infections in sepsis patients. Augmented host inflammatory response was generated in S. aureus infections as compared with E. coli.

RESUMEN

BACKGROUND: Improvements in health-related outcomes for critically ill adults in low and lower-middle income countries need systematic investments in research capacity and infrastructure. High-quality research has been shown to strengthen health systems; yet, research contributions from these regions remain negligible or absent. We undertook a scoping review to describe barriers and facilitators for the conduct of critical care research. METHODS: We searched MEDLINE and EMBASE up to December 2021 using a strategy that combined keyword and controlled vocabulary terms. We included original studies that reported on barriers or facilitators to the conduct of critical care research in these settings. Two reviewers independently reviewed titles and abstracts, and where necessary, the full-text to select eligible studies. For each study, reviewers independently extracted data using a standardized data extraction form. Barriers and facilitators were classified along the lines of a previous review and based on additional themes that emerged. Study quality was assessed using appropriate tools. RESULTS: We identified 2693 citations, evaluated 49 studies and identified 6 for inclusion. Of the included studies, four were qualitative, one was a cross-sectional survey and one was reported as an 'analysis'. The total number of participants ranged from 20-100 and included physicians, nurses, allied healthcare workers and researchers. Barriers identified included limited funding, poor institutional & national investment, inadequate access to mentors, absence of training in research methods, limited research support staff, and absence of statistical support. Our review identified potential solutions such as developing a mentorship network, streamlining of regulatory processes, implementing a centralized institutional research agenda, developing a core-outcome dataset and enhancing access to low-cost technology. CONCLUSION: Our scoping review highlights important barriers to the conduct of critical care research in low and lower-middle income countries, identifies potential solutions, and informs researchers, policymakers and governments on the steps necessary for strengthening research systems.

RESUMEN

Direct oral anticoagulants (DOACs) are being increasingly used in patients with chronic thromboembolic hypertension (CTEPH), however, the data on their safety and efficacy are scarce and contradictory. We systematically searched MEDLINE and Google Scholar databases from January 2010 to January 2021 for studies of DOACs in CTEPH. Three observational studies, 2 abstracts and one case series met our inclusion criteria. While these studies reported similar or even less rates of major bleeding in patients receiving DOACs compared with vitamin K antagonists, there were concerns about the possibility of increased risk of venous thromboembolism recurrence with DOAC therapy. Further studies are warranted to better define the role of DOACs in CTEPH.

RESUMEN

Background and aim Adenomatous polyps are precursor lesions for colorectal cancer (CRC). Serrated adenomas/polyps are considered a risk factor for the development of proximal and interval CRC. African-Americans are at higher risk for right-sided CRC. Minimal data evaluating serrated adenoma characteristics by race/ethnicity on initial screening colonoscopy (SC) exist. The aim of this investigation was to compare the characteristics of serrated adenomas found in non-Hispanic whites (nHw) and African-Americans (AA) undergoing initial SC. Methods The University of Florida-Jacksonville endoscopy database was searched for all SC performed between January 2000 and December 2014. Inclusion criteria were nHw or AA race/ethnicity and histologically proven serrated adenoma found at SC. Data were collected for all included age at SC, sex, number, location, and size of serrated adenomas found. Results A total of 8693 individuals (nHw - 4199 and AA - 4494) underwent SC between January 2000 and December 2014. Serrated adenomas were found in 479 individuals (nHw, n=294; AA, n=185), and AA were significantly less likely than nHw to have serrated adenomas on SC (AA 4.1% vs nHw 7%; p< 0.0001). No difference was observed in mean age, location, or size between nHw and AA with serrated adenomas. Conclusions Serrated adenomas are more frequent in nHw compared to AA at initial SC. No difference was seen in size or location of serrated adenomas, as well as patient age, between AA and nHw. A study of genetic factors predisposing to serrated adenoma formation and the impact of socioeconomic disparities should be performed across ethnic groups to understand this difference.

RESUMEN

BACKGROUND: Coronavirus disease-19 (COVID-19) infection is associated with an uncontrolled systemic inflammatory response. Statins, given their anti-inflammatory properties, may reduce the associated morbidity and mortality. This study aimed to determine the association between statin use prior to hospitalization and in-hospital mortality in COVID-19 patients. METHODS: In this retrospective study, clinical data were collected from the electronic medical records of patients admitted to the hospital with confirmed COVID-19 infection from March 1, 2020 to April 24, 2020. A multivariate regression analysis was performed to study the association of pre-admission statin use with in-hospital mortality. RESULTS: Of 255 patients, 116 (45.5%) patients were on statins prior to admission and 139 (54.5%) were not. The statin group had a higher proportion of end stage renal disease (ESRD) (13.8% vs. 2.9%, p = 0.001), diabetes mellitus (63.8% vs. 35.2%, p<0.001), hypertension (87.9% vs. 61.1%, p < 0.001) and coronary artery disease (CAD) (33.6% vs. 5%, p < 0.001). On multivariate analysis, we found a statistically significant decrease in the odds of in-hospital mortality in patients on statins before admission (OR 0.14, 95% CI 0.03- 0.61, p = 0.008). In the subgroup analysis, statins were associated with a decrease in mortality in those with CAD (OR 0.02, 95% CI 0.0003-0.92 p = 0.045) and those without CAD (OR 0.05, 95% CI 0.005-0.43, p = 0.007). CONCLUSIONS: Our study suggests that statins are associated with reduced in-hospital mortality among patients with COVID-19, regardless of CAD status. More comprehensive epidemiological and molecular studies are needed to establish the role of statins in COVID-19.

RESUMEN

OBJECTIVES: Accurate diagnosis and management of undifferentiated diffuse parenchymal lung disease (DPLD) in critically ill patients is challenging. Transbronchial forceps biopsies have limited utility and surgical lung biopsies can be detrimental for critically ill patients. Transbronchial cryobiopsy (TBC) has shown increased diagnostic yield compared to conventional forceps biopsy in DPLD. However, TBC has not been studied in intensive care unit (ICU) patients. In this case series, we describe our experience with TBC for diagnosis of DPLD in ICU patients with acute hypoxemic respiratory failure. METHODS: This case series includes critically ill patients who underwent TBC at two different tertiary care hospitals. Procedures were performed by the same interventional pulmonologist using the two therapeutic bronchoscopes with a 2.8-mm working channel, and a 1.9- or 2.4-mm cryoprobe. RESULTS: We performed TBC in 17 patients of which 12 (70.1%) were performed at bedside in ICU without fluoroscopic guidance. Pathological diagnosis was made in 15 (88%) patients which resulted in changes in management in most of these patients. Six patients (35.3%) developed pneumothorax post-procedure with 5 (29.4%) requiring a chest tube. Moderate bleeding was noted in one (6%) patient and no severe or fatal bleeding occurred. Our 30-day ICU mortality was 47% (n = 8); however, no deaths were directly attributable to the procedure. CONCLUSIONS: TBC is a feasible technique with an acceptable complication rate and a fairly high histopathological yield in ICU patients with DPLD and acute hypoxemic respiratory failure. Appropriate diagnosis can be crucial in making management decisions for these patients.

RESUMEN

To study whether a diagnosis of cancer affects the clinical presentation and outcomes of patients with pulmonary embolism (PE). A retrospective analysis was performed of all consecutive patients diagnosed with PE on a computed tomography scan from 2014 to 2016 at an urban tertiary-referral medical center. Baseline characteristics, treatment decisions, and mortality data were compared between study subjects with and without a known diagnosis of active cancer. There were 581 subjects, of which 187 (33.0%) had a diagnosis of cancer. On average, cancer subjects tended to be older (64.8 vs. 58.5 years, p < 0.01), had lower body mass index (BMI) (29.0 vs. 31.5 kg/m2, p = 0.01), and were less likely to be active smokers (9.2% vs. 21.1%, p < 0.01), as compared to non-cancer subjects. Cancer subjects were also less likely to present with chest pain (18.2% vs. 37.4%, p < 0.01), syncope (2.7% vs. 6.6%, p = 0.05), bilateral PEs (50% vs. 60%, p = 0.025), and evidence of right heart strain (48% vs. 58%, p = 0.024). There was no difference in-hospital length of stay (8.9 vs. 9.4 days, p = 0.61) or rate of intensive care unit (ICU) admission (31.9% vs. 33.3%, p = 0.75) between the two groups. Presence of cancer increased the risk of all-cause one-year mortality (adjusted HR 9.7, 95% CI 4.8-19.7, p < 0.01); however, it did not independently affect in-hospital mortality (adjusted HR 2.9, 95% CI 0.86-9.87, p = 0.086). Patients with malignancy generally presented with less severe PE. In addition, malignancy did not independently increase the risk of in-hospital mortality among PE patients.

RESUMEN

BACKGROUND: Although it is well known that the coronavirus disease (COVID-19) pandemic has had a profound effect on health care, its impact on fellowship training in Pulmonary and Critical Care Medicine (PCCM) has not been well described. OBJECTIVE: We conducted an anonymous survey of PCCM program directors (PDs) to assess the impact of the COVID-19 pandemic on PCCM fellowship training across the United States. METHODS: We developed a 30-question web-based survey that was distributed to U.S. PCCM PDs through the Association of Pulmonary and Critical Care Medicine Program Directors. RESULTS: The survey was sent to 242 PDs, of whom 28.5% responded. Most of the responses (76.8%) came from university-based programs. Almost universally, PDs reported a decrease in the number of pulmonary function tests (100%), outpatient visits (94.1%), and elective bronchoscopies (96%). Three-quarters (77.6%) of the PDs reported that their PCCM fellows spent more time in the intensive care unit than originally scheduled. CONCLUSION: The COVID-19 pandemic has had a variable impact on different aspects of fellowship training. PDs reported a significant decrease in the core components of pulmonary training, whereas certain aspects of critical care training increased. It is likely that targeted mitigation strategies will be needed to ensure no gaps in PCCM training while optimizing well-being.

RESUMEN

BACKGROUND: Inappropriate antibiotic therapy in sepsis is associated with poor outcomes, clinicians often provide routine coverage for multidrug resistant (MDR) bacteria. However, these regimens may contribute to problems related to antibiotic overuse. To understand the incidence and related factors of multidrug resistant bacterial infections in ED patients with sepsis, we examined how often patients with sepsis in our emergency department had MDR infections. We also explored risk factors for, and outcomes from, MDR bacterial infections. METHODS: We reviewed records of patients presenting to our emergency department (ED) meeting criteria for severe sepsis or septic shock from March 2012 to July 2013. Patient demographics, comorbidities, preadmission location, and APACHE II scores were analyzed, as were clinical outcomes. RESULTS: A total of 191 episodes were examined. 108 (57%) cases were culture-positive, and of these, 23 (12.0%) had an MDR pathogen recovered. Among patients with positive cultures, MDR patients used mechanical ventilation more often 29% vs. 52% (P = 0.03) and had longer mean ICU and hospital length of stays: 4.0 vs 9.3 (P < 0.08) and 10.6 vs 20.8 (P = 0.01), respectively. We did not identify statistically significant predictors of MDR infection. CONCLUSIONS: The overall number of infections due to MDR bacteria was low, and MDR gram-negative infections were uncommon. The use of multiple empiric antibiotics for resistant gram-negative infections in the ED may be beneficial in only a small number of cases. Additionally, empiric coverage for vancomycin-resistant enterococci may need to be considered more often. Larger studies may help further elucidate the rates of MDR infections in ED patients, and identify specific risk factors to rationally guide empiric antibiotic treatment.

RESUMEN

We report a case of a 59-year-old male with a one-month history of pleuritic chest pain who was diagnosed with tracheobronchopathia osteochondroplastica (TO). TO is a rare benign condition characterized by protruding submucosal nodules into the tracheobronchial lumen. The disease is generally asymptomatic, with rare cases of progressive nodularity, cough, dyspnoea, and haemoptysis. Diagnosis can be made via bronchoscopic visualization of bony and cartilaginous nodules on tracheal walls. Although generally benign, the rarity of this condition makes diagnosis difficult even for trained pulmonologists and frequently predisposes patients to unnecessary invasive diagnostic testing and improper management of symptoms and contributing co-morbid conditions. We present this case to increase physician and patient awareness about this disease to help improve diagnostic strategy and knowledge of disease manifestations and potential complications.

RESUMEN

INTRODUCTION: Driving pressure (DP) while on ECMO has been studied in acute respiratory distress syndrome (ARDS) but no studies exist in those on ECMO without ARDS. We aimed to study association of mortality with DP in all patients on ECMO and compare change in DP before and after initiation of ECMO. METHODS: Consecutive patients placed on ECMO either veno-arterial ECMO or veno-venous ECMO between August 2010 and February 2017 were reviewed. The outcomes were compared based on DP before and after ECMO initiation. RESULTS: A total of 192 patients were included: 68 (35%) had ARDS while 124 (65%) did not. There were 70 individuals for whom DP was available, 33 (47%) had a decrease in DP, whereas 32 (46%) had an increase in DP and 5 (7%) had no change in DP after ECMO initiation. Those with an increase in DP had a higher initial PEEP (14 vs 9 cm H2O, p < 0.001) and a higher PEEP decrease after ECMO (6.4 cm H2O vs by 2.5 cm H2O, p < 0.001). Those with an increase in DP had a significantly longer stay on ECMO than those without (p = 0.022). On multivariable analysis, higher DP 24 h after ECMO initiation was associated with an increase in 30-day mortality (OR 1.15, 75% CI 1.07-1.24, p ≤ 0.001). CONCLUSION: A significant proportion of patients experienced an increase in driving pressure and decrease in compliance after initiation of ECMO. Higher driving pressure after initiation of ECMO is associated with increased adjusted 30-day mortality. Individualized ventilator strategies are needed to reduce mechanical stress while on ECMO.

RESUMEN

BACKGROUND: Clinical and epidemiological differences between acute respiratory distress syndrome (ARDS) that presents at the initiation of mechanical ventilation [MV] (ARDS at MV onset) and that which develops during the course of MV (ARDS after MV onset) are not well understood. We conducted an observational study in five Peruvian ICUs to characterize differences between ARDS at MV onset and after MV onset and identify risk factors for the development of ARDS after MV onset. METHODS: We consecutively enrolled critically ill patients with acute respiratory failure requiring at least 24 h of mechanical ventilation and followed them prospectively during the first 28 days and compared baseline characteristics and clinical outcomes by ARDS status. RESULTS: We enrolled 1657 participants on MV (mean age 60.0 years, 55% males) of whom 334 (20.2%) had ARDS at MV onset and 180 (10.9%) developed ARDS after MV onset. Average tidal volume at the initiation of MV was 8.7 mL/kg of predicted body weight (PBW) for participants with ARDS at MV onset, 8.6 mL/kg PBW for those who developed ARDS after MV onset, and 8.5 mL/kg PBW for those who never developed ARDS (p = 0.23). Overall, 90-day mortality was 56% and 55% for ARDS after MV onset and ARDS at MV onset, respectively, as compared to 46% among those who never developed ARDS (p < 0.01). Adults with ARDS had a higher body mass index (BMI) than those without ARDS (27.3 vs 26.5 kg/m2, p < 0.01). Higher peak pressure (adjusted interquartile OR = 1.51, 95% CI 1.21-1.88), higher mean airway pressure (adjusted interquartile OR = 1.41, 95% CI 1.13-1.76), and higher positive end-expiratory pressure (adjusted interquartile OR = 1.29, 95% CI 1.10-1.50) at MV onset were associated with a higher odds of developing ARDS after MV onset. CONCLUSIONS: In this study of mechanically ventilated patients, 31% of study participants had ARDS at some point during their ICU stay. Optimal lung-protective ventilation was not used in a majority of patients. Patients with ARDS after MV onset had a similar 90-day mortality as those with ARDS at MV onset. Higher airway pressures at MV onset, higher PEEP, and higher BMI were associated with the development of ARDS after MV onset.

RESUMEN

BACKGROUND: Previous study from this lab has discerned oxidative, nitrosative stress and their relationship with cytokines contributing to the severity of sepsis and organ dysfunction. Cytokines are known to induce neutrophil extracellular traps (NETs) formation via free radicals generation. Hyper-activation of neutrophil leads to the increased NETs formation or ineffective clearance of NETs would likely increase the risk of auto-antibody generation against NETs components and being partly responsible for the sepsis severity and organ dysfunction. The present study was undertaken to further assess the status of NETs formation and their correlation with severity of sepsis, with the cytokines and organ dysfunction. METHODS: The level of NETs formation, DNA release, elastase release, and inflammatory cytokines was determined in 80 sepsis patients and 45 healthy volunteers. Their linearity with organ parameters and associations with sepsis severity were also assessed. RESULTS: NETs formation experiment was carried out and it was significantly higher in sepsis (70%) compared to control (30%). NETs % were positively correlated with severity of sepsis and organ dysfunction. Pearson's correlation coefficient demonstrated a direct relation between NETs components and organ parameters with Sepsis severity scores. CONCLUSION: NETs formation is significantly higher due to which it is contributing to the sepsis severity and organ failure.
