RESUMO
Waldenström macroglobulinemia (WM) is a chronic B-cell lymphoproliferative disorder characterized by lymphoplasmacytic cell overgrowth in the bone marrow and increased secretion of IgM immunoglobulins into the serum. Patients with WM have a variety of clinical outcomes, including long-term survival but inevitable recurrence. Recent advances in disease knowledge, including molecular and genetic principles with the discovery of MYD88 and CXCR4 mutations, have rapidly increased patient-tolerable treatment options. WM patients may benefit from chemotherapy regimens that include rituximab-based regimens, alkylating drugs, proteasome inhibitors, monoclonal antibodies, and drugs targeting Bruton tyrosine kinase inhibitors. In light of these advancements, patients can now receive treatment customized to their specific clinical characteristics, focusing on enhancing the depth and durability of their response while limiting the adverse effects. Despite the rapidly developing therapeutic armament against WM, a lack of high-quality evidence from extensive phase 3 trials remains a significant challenge in the research. We believe clinical outcomes will keep improving when new medicines are introduced while preserving efficacy and minimizing toxicity.
RESUMO
BACKGROUND: Despite routine evaluation of cytogenetics in myeloma, little is known regarding the impact of high-dose therapy (HDT) consolidation on overall survival (OS) or progression-free survival (PFS) in patients who have high-risk cytogenetics. The authors performed a meta-analysis of randomized controlled trials (RCTs) to assess the heterogeneity of HDT efficacy according to cytogenetic risk. METHODS: All RCTs in patients who had newly diagnosed myeloma from 2000 to 2021 that compared upfront HDT versus standard-dose therapy (SDT) consolidation were included. The primary objective was to assess the difference in HDT efficacy between standard-risk and high-risk cytogenetics in terms of the OS or PFS log(hazard ratio) (HR). The pooled OS and PFS HR was calculated according to cytogenetic-risk subgroup using a random-effects model, and heterogeneity (I2 ) (the percentage of total observed variability explained by between-study differences) was assessed using an interaction test. RESULTS: After screening 3307 citations, 6 RCTs were included for PFS analysis, and 4 were included for OS analysis. The median follow-up ranged from 3.1 to 7.8 years. The pooled OS HR for HDT versus SDT consolidation in patients with standard-risk and high-risk cytogenetics was 0.90 (95% confidence interval [CI], 0.70-1.17; I2 = 0%) and 0.66 (95% CI, 0.45-0.97; I2 = 0%), respectively. The difference in HDT efficacy in terms of OS between standard-risk and high-risk patients was statistically significant in favor of the high-risk group (P for interaction = .03). The pooled PFS HR for HDT versus SDT was 0.65 (95% CI 0.56-0.76; I2 = 0%) versus 0.52 (95% CI, 0.33-0.83; I2 = 55%), respectively. The difference in HDT efficacy in terms of PFS between standard-risk and high-risk patients was not significant (P for interaction = .25). CONCLUSIONS: The magnitude of OS benefit with upfront HDT is cytogenetics-dependent. Patients with high-risk cytogenetics should preferably receive upfront rather than delayed HDT consolidation. LAY SUMMARY: Upfront autologous stem cell transplantation improves overall survival in patients with newly diagnosed myeloma harboring high-risk cytogenetics.

BACKGROUND: The high prevalence of tobacco use in Pakistan poses a substantial health and economic burden to Pakistani individuals, families, and society. However, a comprehensive assessment of the key risk factors of tobacco use in Pakistan is very limited in the literature. A better understanding of the key risk factors of tobacco use is needed to identify and implement effective tobacco control measures. OBJECTIVES: To investigate the key socioeconomic, demographic, and psychosocial determinants of tobacco smoking in a recent large nationally representative sample of Pakistani adults. METHODS: N = 18,737 participants (15,057 females and 3680 males) from the 2017-18 Pakistan Demographic Health Survey, aged 15-49 years, with data on smoking use and related factors were included. Characteristics of male and female participants were compared using T-tests (for continuous variables) and χ2-tests (for categorical variables). Multivariable logistic regression models were used to identify gender-specific risk factors of tobacco use. The Receiver Operating Characteristic Curve test was used to evaluate the predictive power of models. RESULTS: We found that the probability of smoking for both males and females is significantly associated with factors such as their age, province/region of usual residence, education level, wealth, and marital status. For instance, the odds of smoking increased with age (from 1.00 [for ages 15-19 years] to 3.01 and 5.78 respectively for females and males aged 45-49 years) and decreased with increasing education (from 1.00 [for no education] to 0.47 and 0.50 for females and males with higher education) and wealth (from 1.00 [poorest] to 0.43 and 0.47 for richest females and males). Whilst the odd ratio of smoking for rural males (0.67) was significantly lower than that of urban males (1.00), the odds did not differ significantly between rural and urban females. Finally, factors such as occupation type, media influence, and domestic violence were associated with the probability of smoking for Pakistani females only. CONCLUSIONS: This study identified gender-specific factors contributing to the risk of tobacco usage in Pakistani adults, suggesting that policy interventions to curb tobacco consumption in Pakistan should be tailored to specific population sub-groups based on their sociodemographic and psychosocial features.

The advancement in the domain of IoT accelerated the development of new communication technologies such as the Message Queuing Telemetry Transport (MQTT) protocol. Although MQTT servers/brokers are considered the main component of all MQTT-based IoT applications, their openness makes them vulnerable to potential cyber-attacks such as DoS, DDoS, or buffer overflow. As a result of this, an efficient intrusion detection system for MQTT-based applications is still a missing piece of the IoT security context. Unfortunately, existing IDSs do not provide IoT communication protocol support such as MQTT or CoAP to validate crafted or malformed packets for protecting the protocol implementation vulnerabilities of IoT devices. In this paper, we have designed and developed an MQTT parsing engine that can be integrated with network-based IDS as an initial layer for extensive checking against IoT protocol vulnerabilities and improper usage through a rigorous validation of packet fields during the packet-parsing stage. In addition, we evaluate the performance of the proposed solution across different reported vulnerabilities. The experimental results demonstrate the effectiveness of the proposed solution for detecting and preventing the exploitation of vulnerabilities on IoT protocols.
RESUMO
This paper explores the features of accounting for the national carbon emission inventory under four different system boundaries, including the presently operational territorial production-based accounting (PBA) practised by the UNFCCC. Using a recently published input-output table with the base year for 2013-2014, the study calculates India's 'Nationally Determined Contribution (NDC)' to the mitigation of carbon emissions using production-based, consumption-based, sharing-based and equity-based accounting. The study finds India as a net importer of carbon emissions, especially for its high emission-intensive capital and energy goods import such that the country is bearing the minimum burden of emission reduction responsibility. However, the study intends to analyse this burden of responsibility in terms of the criteria of justice and effectiveness and addresses the future policy priorities for India to become a net exporter of industrial goods. We recommend India for supporting and implementing an alternative system boundary of emission inventory accounting which would be more consistent with the provisions of 'equity' subscribed under the UNFCCC while at the same time, helpful for achieving the climate goals by appropriately trace and track the sources of 'carbon leakage'.

Coxiella burnetii, an intracellular zoonotic bacterium, causes query (Q) fever in ruminants. Its role has never been elucidated in small ruminants from Pakistan. The current study is designed to (a) determine the prevalence of coxiellosis in small ruminants, (b) evaluate the association of various potential risk factors and biomarkers in the occurrence of Coxiella burnetii, (c) and determine phylogeny and genetic variability of its various isolates identified during the study. For this purpose, 320 blood samples from sheep (n = 160) and goats (n = 160) were collected from 9 Union Councils of district Kasur, Punjab, and processed for DNA extraction. C. burnetii was confirmed by amplification of IS1111 transposase gene with an amplicon size of 294 bp. The results showed that the overall positive percentage of C. burnetii is 36.87% (sheep: 46.9% and goats: 30%). The phylogenetic tree was also constructed which described the possible origin of this pathogen from environment. Besides, after translation into amino acid, the resultant alignment showed several unique changes at position numbers 18 and 27 in the isolates from goats and at 27 and 66 from those of sheep. These mutations can have major impact on the infectious characteristics of this pathogen. Furthermore, different potential risk factors and clinical biomarkers like age, tick infestation, abortion, mastitis, and infertility were also studied and found that these are significantly (p < 0.05) associated with the occurrence of coxiellosis. It is concluded from the study that C. burnetii is endemic in small ruminants in Punjab, Pakistan. The outcomes of this study are alarming for scientific community as well as for policy makers because coxiellosis is an emerging threat to both humans and animals in this region due to its interspecies transmission ability.

Currently, the demand for natural colorants is increasing instead of synthetic colorants for foodstuff, because they are harmless to human health. Betalain is group of compounds containing nitrogen and water soluble pigment. Betalain is classified into two main classes, betacyanin which is the condensation of betalamic acid with cyclo-DOPA and betaxanthin which is the conjugation of amino acid or amines with betalamic acid. They are used to color various foods and medicines. Betalain is different from anthocyanin because betalains contain nitrogen in their structures. It is interesting to hear that betalains and anthocyanins are individually significant but they have not seen together in the same plant. Their stability influenced by various factors such as, temperature, pH, water activity and light. In this review basic chemistry of betalains, classes, subclasses, their sources and biosynthesis, factors affecting their stability, health and food industry applications are discussed. Moreover, mentioned work signifies the potent anticancer, antioxidant and antimalarial activities of betalains, furthermore provides a help to do more scientific work on it.

Between 11 and 37% of extranodal marginal zone lymphoma (EMZL) patients present with disease involvement in multiple mucosal sites (MMS). We analyzed 405 EMZL patients seen between 1995 and 2017: 265 (65.4%) patients presented with stage I disease, 49 of 309 (15.8%) patients with bone marrow involvement, and 35 of 328 (10.7%) patients with monoclonal gammopathy (MG). Forty-three (10.6%) patients had MMS presentation, which was more frequently seen in patients aged >60 years (55.8%). Five (17.9%) of 28 MMS patients had MG. MMS patients commonly exhibited the International Prognostic Index (IPI) >2 (79.1%), Follicular Lymphoma International Prognostic Index (FLIPI) >2 (39.5%), and Mucosa-Associated Lymphoid Tissue Lymphoma International Prognostic Index (MALT-IPI) 2-3 (60.5%). Both MMS presentation and MG were associated with shorter survival univariately. In multivariable Cox regression models, shorter progression-free survival (PFS) and overall survival (OS) were observed in patients with MMS (hazard ratio [HR] = 3.08 and 2.92, respectively), age ≥60 years (HR = 1.52 and 2.45, respectively), and in patients who failed to attain a complete remission following initial therapy (HR = 3.27 and 2.13, respectively). Elevated lactate dehydrogenase was associated with shorter PFS (HR = 1.92), while anemia (HR = 2.46) was associated with shortened OS. MALT-IPI ≥2 (HR = 2.47 and 4.75), FLIPI >2 (HR = 1.65 and 2.09), and IPI >2 (HR = 2.09 and 1.73) were associated with shorter PFS and OS, respectively. Higher grade transformation (HGT) occurred in 11 (25.6%) MMS patients with a 5-year cumulative incidence of 13.2% (95% CI 4.7-26.1%). EMZL patients with MMS presentation represent a novel clinical subset associated with shorter PFS, OS, and higher incidence of HGT that needs novel therapeutic approaches.

The genus Datura comprises wild shrub plants that belong to the Solanaceae family. Naturally, they possess both medicinal and poisonous properties due to the presence of many biologically active phytochemical constituents. Traditionally, Datura had been used for mystic and religious purposes, as a natural drug to treat asthma, pain, gout, boils, abscesses, and wounds, and as psychoactive infusions and fumitories. Different Datura species exhibit diverse ethnopharmacological activities against different diseases, and many ancient and traditional cultures have used various forms of Datura to treat ailments and to prevent many diseases. In this article, we comprehensively summarize various phytochemical constituents isolated from Datura, their pharmacological properties against different diseases, parts of the plants used as traditional therapeutic agents, regions where they are located, and botanical descriptions of different Datura species. The ethnopharmacological properties of Datura may provide new insights for discovery and development of natural drugs. Further research is needed for the investigation of mechanisms of action and to develop safety profiles of the phytochemical constituents isolated from Datura species.

BACKGROUND: Pakistan ranks 149th in the maternal mortality ratio (MMR) and has failed to keep pace with other countries in the region, except Afghanistan, with respect to health indicators. Home deliveries are linked to a higher risk of maternal death; therefore, discouraging home deliveries is imperative to improve maternal health. This study provides a holistic view and analyses factors affecting home birth decisions within the context of maternal socio-demographic characteristics in Pakistan. METHODS: The study exploits the latest data from the Pakistan Demographic and Health Survey (2012-2013), which includes a nationally representative sample of 13,558 women aged 15-49 years. However, the sample was reduced to 6977 women who had given birth in the 5 years preceding the survey. Statistical techniques, including bi-variate and multivariate logistic regression, were used to analyse the data. The dependent variable was dichotomous and coded as 0 for home deliveries and 1 for deliveries at a health facility. The dependent variable was constructed based on information regarding the most recent birth in the 5 years preceding the survey. RESULTS: The study reveals that giving birth at home is highly prevalent among mothers in Pakistan (Baluchistan, 74%; Khyber-Pakhtunkhwa, 53%; Gilgit Baltistan, 46%; Punjab, 45% and Sindh, 34%) because of their difficulty obtaining permission to visit a health facility, financial barriers, the distance to health facilities and transportation. Substantial variation is observed when geo-demographic characteristics are considered. Higher home childbirth rates have been recorded in rural areas compared with those in urban areas (OR 1.32; p ≤ 0.000). The likelihood of home birth is highest (OR 2.67; p = 0.000) among women in Baluchistan province and lowest (OR 0.48; p = 0.000) among mothers in Punjab province. After controlling for all odds ratios and demographic characteristics, the parents' education levels remain a significant factor (p = 0.000) that affects women's decisions to deliver at home rather than at a health facility. CONCLUSION: The study findings provide a better understanding of why women prefer to give birth at home. These results can help policymakers to introduce appropriate interventions to increase the number of deliveries at health facilities. These findings are expected to reduce maternal and neonatal mortality in Pakistan.

BACKGROUND: Postoperative state is characterized by increased thrombotic risk by virtue of platelet activation. Whether aspirin ameliorates this risk in patients with established coronary artery disease undergoing cardiac or noncardiac surgery is unknown. We conducted a systematic review and meta-analysis to compare the risk of major adverse cardiac events (MACE) and the risk of bleeding in patients with early (3-5 or more days before surgery) vs. late discontinuation(<3-5 days)/no discontinuation of aspirin. METHODS: Multiple databases were searched from inception of these databases until March 2015 to identify studies that reported discontinuation of aspirin in patients undergoing surgery. The outcomes measured were all cause mortality, nonfatal myocardial infarction and other relevant thrombotic events (MACE) which also may include, fatal and nonfatal MI, stent thrombosis and restenosis, stroke, perioperative cardiovascular complications (heart failure, MI, VTE, acute stroke) and perioperative bleeding during the perioperative period to up to 30 days after surgery. RESULTS: A total of 1,018 titles were screened, after which six observational studies met the inclusion criteria. Our analysis suggests that there is no difference in MACE with planned discontinuation of aspirin (OR = 1.17, 95% CI = 0.76-1.81; P = 0.05; I2 = 55%). Early discontinuation of aspirin showed a decreased risk of peri-operative bleeding (OR 0.82, 95% CI = 0.67-0.99; P = 0.04; I2 = 42%). CONCLUSION: Our analysis suggests that planned short-term discontinuation in the appropriate clinical setting appears to be safe in the correct clinical setting with no increased risk of thrombotic events and with a decreased risk of bleeding. © 2016 Wiley Periodicals, Inc.

OBJECTIVES: We sought to pool data from all studies with reported strut-level data in human subjects evaluated by optical coherence tomography (OCT) surveillance and to compare the aggregate data of stent strut coverage on a longitudinal temporal timeline from initial implantation for different coronary stent subtypes. BACKGROUND: Delayed strut coverage following drug-eluting stent (DES) implantation is an important contributor to late stent thrombosis (LST). OCT can detect stent strut coverage. METHODS: We conducted a systematic search of published or presented studies reporting OCT stent strut coverage of bare-metal stents (BMS) and DES in PubMed, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials to June 2014. Data from 3,515 patients with strut-level data on 731,761 struts were analyzed. RESULTS: The temporal kinetics of strut coverage differed according to stent type. The rate of strut coverage, reflected by the calculated regression coefficient, was found to be the highest in BMS, followed by early generation zotarolimus-eluting stent, everolimus-eluting stent, newer-generation zotarolimus-eluting stent, paclitaxel-eluting stent, and sirolimus-eluting stent (p < 0.0001). CONCLUSIONS: Aggregate rates of stent strut coverage assessed by OCT surveillance differed according to stent type. The clinical implications of these differences require further study but may underlie the differences in rates of stent thrombosis observed in clinical trials with different stent types. © 2015 Wiley Periodicals, Inc.

In the realm of infective endocarditis, a distinct and infrequent player emerges - Pasteurella multocida, an organism more commonly associated with zoonotic infections, now warranting careful consideration in this unique case report. P . multocida is a Gram-negative, facultative anaerobic cocco-bacillus and a common member of the oral bacterial flora of cats and dogs. In humans, it commonly causes skin and wound infections after bites and scratches. Disseminated P . multocida infection seeded into the heart valve is very rare and has only been reported in about one case per year worldwide with only 42 cases found in the literature and only five cases reported to have underlying liver cirrhosis as in our case. This is a case of a 73-year-old female with a past medical history of Child-Pugh B liver cirrhosis secondary to primary biliary cholangitis with portal hypertension, splenomegaly, pancytopenia, severe aortic stenosis, and paroxysmal atrial fibrillation presented to hospital with generalized weakness, fever, and new lower extremity rash 48 hours after last dose of antibiotic. She had recent hospitalization for left lower extremity cellulitis and P. multocida bacteremia and received 14 days of high-dose oral amoxicillin-clavulanate with negative blood culture prior to discharge. She occasionally helps her son to feed his cats and dog whenever he travels. She was readmitted and a repeat blood culture showed P. multocida. Transthoracic echocardiogram showed a 1.9 cm × 1 cm mobile mass attached to the anterior mitral valve leaflet, which was new compared to the prior study obtained during her first admission. She was not a suitable candidate for valve surgery due to her comorbidities. P. multocida was found to be susceptible to penicillin, ampicillin, levofloxacin with negative beta lactamase. Her cellulitis, fever, and bacteremia eventually resolved with intravenous antibiotics. She was ultimately discharged with a two-week course of intravenous ceftriaxone, continued with oral levofloxacin to complete six weeks of total treatment, and followed by long-term penicillin suppression. In this case report, we delve into a rare and intriguing clinical presentation of P . multocida endocarditis. Our patient is the second reported case which showed complication of native mitral valve endocarditis even in the setting of bacteremia resolution. This report sheds light on the challenging diagnosis and management of this uncommon yet clinically significant condition, highlighting the importance of vigilant and prompt intervention in cases of infective endocarditis with atypical causative agents.
RESUMO
BACKGROUND: Prehypertension is a preclinical state of hypertension which leads to an increased likelihood of coronary heart disease, myocardial infarction, cerebrovascular disease as well as target organ damage. Addressing pre-hypertension through early lifestyle interventions is crucial to mitigating these detrimental effects and improving long-term health outcomes. So, the main objective of this study is to develop a lifestyle intervention program (LSIP) for the management of prehypertension using consensus building approach. METHODS: It was a three round online modified Delphi study with 70 members panellists. All panellists had an experience of prehypertension either as patients (n = 30) or professionals (n = 40). Round 1 included initial recommendations developed from a previous systematic review and metanalysis, which were rated by panellists for their importance on a 5-point Likert scale. Panellists could also suggest additional items in the Round 1. Round 2 and 3 included all items from the Round 1 with new items suggested by the panellists. Data was analysed descriptively using SPSS version 29. All items receiving at least 70% of all respondents combined rating of 'Important' and 'Very Important' in Round 3 were included in the final set of recommendations. RESULTS: Fifty-one panellists (80.9%) (patients = 25, professionals = 26) completed Round 3. Twenty-six recommendation items were included in the Round 1. Twenty new items were added in Round 2 with 46 total items in Round 2 and 3. Thirty-five of these items reached consensus in Round 3. The final set of recommendation comprised of 15 educational. 10 dietary, and 10 exercise recommendations. CONCLUSION: This modified Delphi study developed a comprehensive LSIP for the prevention of prehypertension, incorporating a holistic approach with educational, dietary, and exercise components aimed at the general population. Previously established standards of care (SOC) for managing prehypertension varied significantly and often provided fragmented guidance particularly on physical activity and education. This preventive model offers a novel and scalable approach for early intervention in prehypertension, potentially reducing reliance on medications and improving long-term health outcomes.

BACKGROUND: Psychological distress (PD) is a major health problem that affects all aspects of health-related quality of life including physical, mental and social health, leading to a substantial human and economic burden. Studies have revealed a concerning rise in the prevalence of PD and various mental health conditions among Australians, particularly in female individuals. There is a scarcity of studies that estimate health state utilities (HSUs), which reflect the overall health-related quality of life in individuals with PD. No such studies have been conducted in Australia thus far. OBJECTIVE: We aimed to evaluate the age-specific, sex-specific and PD category-specific HSUs (disutilities) in Australian adults with PD to inform healthcare decision making in the management of PD. METHODS: Data on age, sex, SF-36/SF6D responses, Kessler psychological distress (K10) scale scores and other characteristics of N = 15,139 participants (n = 8149 female individuals) aged >15 years were derived from the latest wave (21) of the nationally representative Household, Income and Labor Dynamics in Australia survey. Participants were grouped into the severity categories of no (K10 score: 10-19), mild (K10: 20-24), moderate (K10: 25-29) and severe PD (K10: 30-50). Both crude and adjusted HSUs were calculated from participants' SF-36 profiles, considering potential confounders such as smoking, marital status, remoteness, education and income levels. The calculations were based on the SF-6D algorithm and aligned with Australian population norms. Additionally, the HSUs were stratified by age, sex and PD categories. Disutilities of PD, representing the mean difference between HSUs of people with PD and those without, were also calculated for each group. RESULTS: The average age of individuals was 46.130 years (46% male), and 31% experienced PD in the last 4 weeks. Overall, individuals with PD had significantly lower mean HSUs than those likely to be no PD, 0.637 (95% confidence interval [CI] 0.636, 0.640) vs 0.776 (95% CI 0.775, 0.777) i.e. disutility: -0.139 [95% CI -0.139, -0.138]). Mean disutilities of -0.108 (95% CI -0.110, -0.104), -0.140 (95% CI -0.142, -0.138), and -0.188 (95% CI -0.190, -0.187) were observed for mild PD, moderate PD and severe PD, respectively. Disutilities of PD also differed by age and sex groups. For instance, female individuals had up to 0.049 points lower mean HSUs than male individuals across the three classifications of PD. There was a clear decline in health-related quality of life with increasing age, demonstrated by lower mean HSUs in older population age groups, that ranged from 0.818 (95% CI 0.817, 0.818) for the 15-24 years age group with no PD to 0.496 (95% CI 0.491, 0.500) for the 65+ years age group with severe PD). Across all ages and genders, respondents were more likely to report issues in certain dimensions, notably vitality, and these responses did not uniformly align with ageing. CONCLUSIONS: The burden of PD in Australia is substantial, with a significant impact on female individuals and older individuals. Implementing age-specific and sex-specific healthcare interventions to address PD among Australian adults may greatly alleviate this burden. The PD state-specific HSUs calculated in our study can serve as valuable inputs for future health economic evaluations of PD in Australia and similar populations.

Prior literature is substantive in highlighting the nexus between pollutant and socio-economic predictors; however, the role of human interaction has not been sufficiently explored. Thus, the present study examines the validity of the environmental Kuznets Curve (EKC) hypothesis in the presence of energy consumption, overpopulation, and human capital index in five South Asian countries. It employs fixed effects, random effects, and dynamic panel causality techniques with a set of panel data from 1972 to 2021. The baseline results validate the existence of the EKC hypothesis in the recipient panel. Nevertheless, the findings reveal that energy consumption and population density have positive effects, while human capital has negative impacts on CO2 emissions. Furthermore, the study observes that energy consumption and per capita GDP have a significant causal link with CO2 emissions, whereas CO2 emissions are evident to have causality with population density and human capital index. The results are robust and suggest that the consolidation of an effective regulatory framework and technological improvements are substantial measures to improve environmental quality in South Asia. Moreover, allocating sufficient resources to uplift contemporary educational and health status would be imperative to improving environmental quality as aspired to by the Paris Agreement.

The majority of cyanotic congenital cardiac defects are caused by the tetralogy of Fallot. Some symptoms include a biventricular connection of the aortic root, right ventricular hypertrophy, blockage of the right ventricular outflow tract, and a ventricular septal defect. Our understanding of tetralogy of Fallot (TOF) has significantly advanced since it was first described in 1888, and early diagnosis has led to improved surgical management and increased life expectancy. Adults with unrepaired and repaired TOF present with a range of late complications, including heart failure, the need for re-interventions, and late arrhythmias. Right ventricular (RV) failure, often caused by chronic pulmonary regurgitation, is a significant cause of heart failure in patients with TOF. Current treatment options are limited, and mainstay surgical procedures such as pulmonary-valve replacement (PVR), trans-annular repair (TAR), or infundibular widening repair have not shown a significant reduction in preventing right ventricular (RV) failure or death. Here, we explain the mechanisms of RV failure in ToF, chronic pulmonary regurgitation, heart failure, and secondary polycythemia. HF management in untreated adults is discussed. The progression of the disease, as well as complications, are also discussed. The treatment plan and the need to investigate the best management approach for this unsolved problem are included. This review aims to fill the knowledge gaps and supply valuable information regarding mechanisms of RV failure, chronic pulmonary regurgitation, and secondary polycythemia. To summarize, a new combat strategy must be found to battle RVF, and a more profound vision of these mechanisms is required. If it is not corrected, it will be one of the future research lines that will contribute to designing more efficacious treatment techniques for adults with TOF.
RESUMO
Purpose: The purpose of this study was to analyze potential differences in antitumor efficacy and pharmacokinetics between intravenous (IV) bendamustine (BEN) and a novel orally administered bendamustine agent (PO) that is utilizing the beneficial properties of superstaturated solid dispersions formulated in nanoparticles. Methods: Pharmacokinetics of IV versus PO BEN were determined by analysis of plasma samples collected from NSG mice treated with either IV or PO BEN. Plasma samples were analyzed using liquid chromatography-mass spectrometry (LC/MS/MS) following a liquid-liquid extraction to determine peak BEN concentration (Cmax), area under the concentration-time curve (AUC) and the half-life (t1/2) in-vivo. in-vitro cytotoxicity of BEN against human non-Hodgkin's Burkitt's Lymphoma (Raji), multiple myeloma (MM.1s), and B-cell acute lymphoblastic leukemia (RS4;11) cell lines was determined over time using MTS assays. Luciferase-tagged versions of the aforementioned cell lines were used to determine in-vivo BEN cytotoxicity of IV versus PO BEN at two different doses. Results: Bendamustine at a high dose in-vitro causes cell death. There was no significant difference in antitumor efficacy between IV and novel PO BEN at a physiologically relevant concentration in all three xenograft models. In-vivo pharmacokinetics showed the oral bioavailability of BEN in mice to be 51.4%. Conclusions: The novel oral BEN agent tested exhibits good oral bioavailability and systemic exposure for in-vivo antitumor efficacy comparable to IV BEN. An oral BEN formulation offers exciting clinical potential as an additional method of administration for bendamustine and warrants further evaluation in clinical studies.
