Impact of Lung Cancer on Health-Related Quality of Life, Financial Toxicity, and Household Economics in Patients From the Public and the Private Healthcare Sector in Argentina.

OBJECTIVES: Non-small cell lung cancer (NSCLC) is Argentina's first cause of cancer death. Most patients have an advanced stage at diagnosis, with poor expected survival. This study aimed to characterize the health-related quality of life (HRQOL) and economic impact of patients treated in the private healthcare sector and compare it with that of the public sector. METHODS: We undertook an observational cross-sectional study that extended a previous study to a referral private center in Argentina. Outcomes included the EuroQol EQ-5D-3L (to assess HRQOL), Comprehensive Score for Financial Toxicity (financial toxicity instrument), Work Productivity and Activity Impairment - General Health (to assess productivity loss), and out-of-pocket expenses in adults diagnosed of NSCLC. RESULTS: We included 30 consecutive patients from a private healthcare center (July 2021 to March 2022), totaling 131 patients (n = 101 from previous public study). The whole sample had low quality of life and relevant economic impact. Patients in the private healthcare sector showed lower disease severity and higher educational level and household income. In addition, private healthcare system patients showed higher utility (0.77 vs 0.73; P < .05) and lower impairment of daily activities (41% vs 59%; P = .01). Private health system patients also showed lower financial toxicity as measured by the Comprehensive Score for Financial Toxicity score (23.9 vs 20.14; P < .05) but showed no differences when financial toxicity was assessed as a dichotomic variable. CONCLUSIONS: Although patients with NSCLC treated in a private healthcare center in Argentina showed a relevant HRQOL and economic impact, this impact was smaller than the one observed in publicly funded hospitals.

Ether lipids and a peroxisomal riddle in sperm.

Sperm are terminally differentiated cells that lack most of the membranous organelles, resulting in a high abundance of ether glycerolipids found across different species. Ether lipids include plasmalogens, platelet activating factor, GPI-anchors and seminolipid. These lipids play important roles in sperm function and performance, and thus are of special interest as potential fertility markers and therapeutic targets. In the present article, we first review the existing knowledge on the relevance of the different types of ether lipids for sperm production, maturation and function. To further understand ether-lipid metabolism in sperm, we then query available proteomic data from highly purified sperm, and produce a map of metabolic steps retained in these cells. Our analysis pinpoints the presence of a truncated ether lipid biosynthetic pathway that would be competent for the production of precursors through the initial peroxisomal core steps, but devoid of subsequent microsomal enzymes responsible for the final synthesis of all complex ether-lipids. Despite the widely accepted notion that sperm lack peroxisomes, the thorough analysis of published data conducted herein identifies nearly 70% of all known peroxisomal resident proteins as part of the sperm proteome. In view of this, we highlight open questions related to lipid metabolism and possible peroxisomal functions in sperm. We propose a repurposed role for the truncated peroxisomal ether-lipid pathway in detoxification of products from oxidative stress, which is known to critically influence sperm function. The likely presence of a peroxisomal-derived remnant compartment that could act as a sink for toxic fatty alcohols and fatty aldehydes generated by mitochondrial activity is discussed. With this perspective, our review provides a comprehensive metabolic map associated with ether-lipids and peroxisomal-related functions in sperm and offers new insights into potentially relevant antioxidant mechanisms that warrant further research.

A novel Xp11.22 duplication involving HUWE1 in a male with syndromic intellectual disability and additional neurological findings.

Sequence variants and duplications in the HECT, UBA and WWE domain -containing 1 (HUWE1) E3 ubiquitin ligase gene have been associated with X-linked mild to severe intellectual disability (ID), but a solid phenotype pattern among the affected males is still remaining to be established. Here, we report a male patient with sporadic, severe and syndromic ID, carrying a novel and unique 842 kb duplication at Xp11.22, including the dosage-sensitive HUWE1 gene and other fifteen curated RefSeq genes. Expression analysis in the patient and his female relatives confirmed increased HUWE1 mRNA levels, with different X-chromosome inactivation patterns among the female carriers. Our patient differs from those previously described by us and others as he presents encephalomalacia at brain Magnetic Resonance Imaging and diffuse bilaterally and synchronous intercritical irritating paroxysms at electroencephalogram. Overall, our clinical, molecular, and neurological findings sum up the previous data, expanding the phenotype spectrum in Xp11.22 copy gains involving the whole HUWE1 gene in both males and female carriers in light of X-chromosome inactivation patterns.

Effects of Dietary n-3 LCPUFA Supplementation on the Hippocampus of Aging Female Mice: Impact on Memory, Lipid Raft-Associated Glutamatergic Receptors and Neuroinflammation.

Long-chain polyunsaturated fatty acids (LCPUFA), essential molecules whose precursors must be dietary supplied, are highly represented in the brain contributing to numerous neuronal processes. Recent findings have demonstrated that LCPUFA are represented in lipid raft microstructures, where they favor molecular interactions of signaling complexes underlying neuronal functionality. During aging, the brain lipid composition changes affecting the lipid rafts' integrity and protein signaling, which may induce memory detriment. We investigated the effect of a n-3 LCPUFA-enriched diet on the cognitive function of 6- and 15-months-old female mice. Likewise, we explored the impact of dietary n-3 LCPUFAs on hippocampal lipid rafts, and their potential correlation with aging-induced neuroinflammation. Our results demonstrate that n-3 LCPUFA supplementation improves spatial and recognition memory and restores the expression of glutamate and estrogen receptors in the hippocampal lipid rafts of aged mice to similar profiles than young ones. Additionally, the n-3 LCPUFA-enriched diet stabilized the lipid composition of the old mice's hippocampal lipid rafts to the levels of young ones and reduced the aged-induced neuroinflammatory markers. Hence, we propose that n-3 LCPUFA supplementation leads to beneficial cognitive performance by "rejuvenating" the lipid raft microenvironment that stabilizes the integrity and interactions of memory protein players embedded in these microdomains.

Hyperammonemia Alters the Function of AMPA and NMDA Receptors in Hippocampus: Extracellular cGMP Reverses Some of These Alterations.

Chronic hyperammonemia alters membrane expression of AMPA and NMDA receptors subunits in hippocampus leading to impaired memory and learning. Increasing extracellular cGMP normalizes these alterations. However, it has not been studied whether hyperammonemia alters the function of AMPA and NMDA receptors. The aims of this work were: (1) assess if hyperammonemia alters AMPA and NMDA receptors function; (2) analyze if extracellular cGMP reverses these alterations. A multielectrode array device was used to stimulate Schäffer collaterals and record postsynaptic currents in the CA1 region in hippocampal slices from control and hyperammonemic rats and analyze different features of the excitatory postsynaptic potentials. Hyperammonemia reduces the amplitude and delays appearance of AMPA EPSPs, whereas increases amplitude, hyperpolarization, depolarization and desensitization area of the NMDA EPSPs. These alterations in AMPA and NMDA function are accentuated as the stimulation intensity increases. Adding extracellular cGMP reverses the alteration in amplitude in both, AMPA and NMDA EPSPs. In control slices extracellular cGMP decreases the AMPA and NMDA EPSPs amplitude and delays the response of neurons and the return to the resting potential at all stimulation intensities. In conclusion, hyperammonemia decreases the AMPA response, whereas increases the NMDA response and extracellular cGMP reverses these alterations.

Evidence-Informed Update of Argentina's Health Benefit Package: Application of a Rapid Review Methodology.

OBJECTIVES: Argentina has a fragmented healthcare system with social security covering almost two thirds of the population. Its benefit package-called compulsory medical program (PMO; by its Spanish acronym Programa Médico Obligatorio)-has not been formally and widely updated since 2005. However, laws, clinical practice guidelines (CPGs), and a high-cost technology reimbursement fund complement it. Our objective was to comprehensively review such a PMO and propose an update considering the corresponding complementary sources. METHODS: We followed four steps: (i) identification of health technologies from the current PMO and complementary sources, (ii) prioritization, (iii) assessment through rapid health technology assessment (HTA), and (iv) appraisal and recommendations. We evaluated three value domains: quality of evidence, net benefit, and economics, which were summarized in a five-category recommendation traffic-light scale ranging from a strong recommendation in favor of inclusion to a strong recommendation for exclusion. RESULTS: Eight hundred fifty technologies were identified; 164 of those, considered as high priority, were assessed through rapid HTAs. Those technologies mentioned in laws and CPGs were mostly outpatient essential medicines, whereas those from the reimbursement system were mostly high-cost drugs; of these 101 technologies, 50 percent were recommended to be kept in the PMO. The other 63 (identified by the Superintendence of Health Services, technology producers, and patients) were mostly medical procedures and high-cost drugs; only 25 percent of those resulted in a favorable recommendation. CONCLUSIONS: A methodology based on four clearly identified steps was used to carry out a comprehensive review of an outdated and fragmented benefit package. The use of rapid HTAs and a traffic-light recommendation framework facilitated the deliberative evidence-based update.

European clinical practice guidelines on the use of chemotherapy for advanced oesophageal and gastric cancers: a critical review using the AGREE II and the AGREE-REX instruments.

PURPOSE: To assess the methodological quality of all relevant and recent European clinical practice guidelines (CPGs) for advanced oesophageal and gastric cancers, and to synthesise their recommendations on the use of chemotherapy. METHODS: We searched PubMed, EMBASE, guidelines repositories, and other sources from 2010 onwards. We appraised quality using AGREE-II and AGREE-REX. RESULTS: 11 CPGs were included (five high, five low, and one moderate quality). Most guidelines showed deficiencies in the domain "applicability", with only three scoring above 60%. Nine did not report having sought the views and preferences of the target population. The lowest scores for AGREE-REX were item Values and Preferences of Target Users (1.6; SD 1.3), and item Values and Preferences of Policy/Decision-Makers (1.8; SD 1.7). The domain Clinical Applicability got the highest score and the domain Implementability got the lowest. CONCLUSIONS: An urgent area of research is how to develop credible and implementable recommendations on the clinical use of CT for advanced oesophageal and gastric cancer.

Critical Care in SARS-CoV-2 Infected Pregnant Women: A Prospective Multicenter Study.

Evidence suggests that pregnant women are at a higher risk of complications compared to the general population when infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and the reasons that lead them to need intensive care are not clear. This is a prospective multicenter study of SARS-CoV-2 positive pregnant women, registered by the Spanish Obstetric Emergency Group, with the objective to define the characteristics of the mothers who were admitted to the Intensive Care Unit (ICU) and to investigate the causes and risk factors for ICU admission. A total of 1347 infected pregnant women were registered and analyzed, of whom, 35 (2.6%) were admitted to the ICU. No differences in maternal characteristics or comorbidities were observed between ICU and non-ICU patients, except for in vitro fertilization and multiple pregnancies. The main causes of admission to the ICU were non-obstetric causes (worsening of the maternal condition and respiratory failure due to SARS-CoV-2 pneumonia, 40%) and a combination of coronavirus disease 2019 (COVID-19) symptoms and obstetrical complications (31.4%). The multivariable logistic analysis confirmed a higher risk of ICU admission when pre-eclampsia or hemorrhagic events coexist with pneumonia. The incidence of thromboembolic events and disseminated intravascular coagulation were also significantly higher among patients admitted to the ICU. Therefore, surveillance and rapid intervention should be intensified in SARS-CoV-2 infected pregnant women with the mentioned risk factors and complications. Emphasis should always be placed on anticoagulant therapy in these patients due to the increased thromboembolic risk, C-section surgery and immobilization in the ICU.

Intracellular and extracelluar cyclic GMP in the brain and the hippocampus.

Cyclic Guanosine-Monophosphate (cGMP) is implicated as second messenger in a plethora of pathways and its effects are executed mainly by cGMP-dependent protein kinases (PKG). It is involved in both peripheral (cardiovascular regulation, intestinal secretion, phototransduction, etc.) and brain (hippocampal synaptic plasticity, neuroinflammation, cognitive function, etc.) processes. Stimulation of hippocampal cGMP signaling have been proved to be beneficial in animal models of aging, Alzheimer's disease or hepatic encephalopathy, restoring different cognitive functions such as passive avoidance, object recognition or spatial memory. However, even when some inhibitors of cGMP-degrading enzymes (PDEs) are already used against peripheral pathologies, their utility as neurological treatments is still under clinical investigation. Additionally, it has been demonstrated a list of cGMP roles as not second but first messenger. The role of extracellular cGMP has been specially studied in hippocampal function and cognitive impairment in animal models and it has emerged as an important modulator of neuroinflammation-mediated cognitive alterations and hippocampal synaptic plasticity malfunction. Specifically, it has been demonstrated that extracellular cGMP decreases hippocampal IL-1ß levels restoring membrane expression of glutamate receptors in the hippocampus and cognitive function in hyperammonemic rats. The mechanisms implicated are still unclear and might involve complex interactions between hippocampal neurons, astrocytes and microglia. Membrane targets for extracellular cGMP are still poorly understood and must be addressed in future studies.

Implementing Strategies at the Workplace Level to Increase Colorectal Cancer Screening Uptake in Argentina: A Controlled Interrupted Time-series Study.

Colorectal cancer is the third most common neoplasm. The immunochemical fecal occult blood test (iFOBT) is recommended for screening. The worksite setting has great potential to deliver preventive interventions. We aimed to design and evaluate the feasibility and potential impact of a multicomponent strategy in a workplace [Internal Revenue Agency of the Province of Buenos Aires (ARBA from its acronym in Spanish "Agencia de Recaudación de Buenos Aires") in Argentina].We used a quasi-experimental research design, a controlled interrupted time-series (ITS). The study involved: (i) a preintervention period (July 2015-September 2018); and (ii) an intervention period (October 2018-February 2019). We used semi-structured interviews and focus groups to design the intervention and to ensure feasibility and implementability. We fitted segmented linear regression models to evaluate changes in the monthly rates per 10,000 tests done in ARBA employees and controlling for the proportion of tests done in non-ARBA workers. A total of 1,552 ARBA employees aged 50 or more participated. Overall, iFOBT mean uptake rates were 16 times higher in the intervened during the five-month intervention period, remaining statistically significant after adjusting by the proportion of tests done in the control group (P < 0.001). The effect was higher in women aged 50 to 59 years. Activities were suspended due to the COVID-19 pandemic. A multifaceted workplace-based intervention proved to be feasible and acceptable to increase the uptake of colorectal cancer screening in employees of Argentina. Achieving high implementation rates requires building a healthy relationship with the partner organization, adding their values and views, and establishing agreed-upon mechanisms. PREVENTION RELEVANCE: Employee-facing multifaceted worksite cancer screening interventions are a valuable means to increase knowledge and utilization of workers. The controlled ITS showed that colorectal cancer screening mean uptake rates were 16 times higher in the intervened versus the control population during the intervention period, particularly among women aged 50 to 75.

Combined use of monensin and virginiamycin to improve rumen and liver health and performance of feedlot-finished steers.

Monensin and virginiamycin are included in beef cattle finishing diets as prophylaxis to minimize the incidence of ruminal acidosis and liver abscesses. Due to different and probably complementary modes of action, this study aimed to determine the effects of a combination of monensin and virginiamycin, both included in the diet at recommended doses, on ruminal health, the occurrence of liver abscesses, and growth performance of feedlot-finished cattle. One hundred and forty-four steers (6 animals/pen) were fed 1 of 3 corn-based finishing diets containing 30 mg of monensin (MN), 25 mg of virginiamycin (VM), or 30 and 25 mg of monensin and virginiamycin (MN + VM), respectively, per kilogram of dry matter. Ruminal pH probes were inserted into two animals per pen and set to record pH every 10 min. On d 100, animals were slaughtered, and rumens and livers were recovered, on which occurrence and degree of ruminal damage, prevalence and number of liver abscesses, and liver scores (A-: livers with no more than two small abscesses; A+: livers with at least one large abscess or more than four medium abscesses; A: any other abscessed liver) were determined. Simultaneous inclusion of monensin and virginiamycin resulted in a 4.3% decrease (P < 0.04) in dry matter intake (DMI; 8.8, 9.2, and 9.2 ± 0.19 kg/d for MN + VM, MN, and VM-fed animals, respectively) and similar (P > 0.13) average daily body weight gain (ADG; 1.49 ± 0.021 kg/d) and hot carcass weight (HCW; 269 ± 1.7 kg), compared with feeding diets containing one additive or the other. Therefore, in terms of ADG, a 9.4% improvement (P < 0.01) in feed efficiency was observed in MN + VM-fed animals. Backfat thickness (5.6 ± 0.08 mm) and ribeye area (69.9 ± 0.53 cm2) remained unaffected (P ≥ 0.74), as well as the minimum (4.98 ± 0.047), mean (6.11 ± 0.037), and maximum ruminal pH (7.23 ± 0.033) values and the time (125 ± 22.3 min/d), area (57.67 ± 12.383 pH × h), and episodes (22 ± 3.8 bouts) of pH below 5.6 (P ≥ 0.12). Overall, prevalence (24 ± 3.4%) and the number of liver abscesses (1.6 ± 0.14 abscesses/abscessed liver), liver scores (20 ± 3.1% of A- and 4 ± 1.8% of A livers), and prevalence (67 ± 3.5%) and degree of damage to the ruminal epithelium (2.5 ± 0.22% affected surface) were similar (P ≥ 0.18) across treatments; however, the occurrence of ruminal lesions tended (P ≤ 0.07) to be associated with that of liver abscesses and reduced ADG when feeding monensin alone.

[Formative research for the design and implementation of a strategy to increase colorectal cancer screening in the workplace in Argentina]. / Investigación formativa para el diseño e implementación de una estrategia para aumentar el rastreo de cáncer colorrectal en el ámbito laboral en Argentina.

The workplace has great potential to disseminate information and implement health promotion activities such as cancer prevention and early detection. Due to the challenges of deploying health interventions in this setting, formative studies are needed to adjust the design and implementation of successful strategies. To inform the intervention's design and implementation and improve the adherence rate to screening with fecal occult blood test in a workplace in Argentina, a formative study was conducted to identify potential barriers and facilitators. The formative study adopted a qualitative methodological design. Interviews were held with 10 individuals in charge of key areas in the institution where the main study was conducted, besides 8 focus groups with workers over 50 years of age. Challenges were identified at the institutional level for the intervention's implementation, such as workers' geographic dispersion and the complexity of the institution's flowchart, as well as at the population level, such as low knowledge about colorectal cancer and diagnostic tests and low risk perception. The facilitators featured the intervention's acceptability and the availability of human and material resources to proceed with the intervention, such as institutional communications channels for disseminating the information and logistics for distribution of diagnostic kits. The formative study allowed identifying resources and potential barriers that informed the intervention's design and implementation.

Surgical resection versus stereotactic radiosurgery on local recurrence and survival for patients with a single brain metastasis: a systematic review and meta-analysis.

BACKGROUND: Brain metastases (BM) are the most frequent intracranial tumours in adults. In patients with solitary BM, surgical resection (SR) or stereotactic radiosurgery (SRS) is performed. There is limited evidence comparing one treatment over the other. OBJECTIVE: To compare SR versus SRS on patients with solitary BMs, regarding local recurrence (LR) and overall survival (OS) conducting a systematic review and meta-analysis. METHODS: Systematic review of literature following PRISMA guidelines, using the databases of Medline, Clinicaltrials.gov, Embase, Web of Science, Sciencedirect, CINAHL, Wiley Online Library, Springerlink and LILACS. Following study selection based on inclusion and exclusion criteria, data extraction and a critical analysis of the literature was performed according to the GRADE scale. For quantitative analysis, a random effects model was used. Data were synthetized and evaluated on a forest plot and funnel plot. RESULTS: Two randomized clinical trials, four cohort studies and one case-control studies met our inclusion criteria for the qualitative analysis. None was excluded subsequently. Overall, 614 patients with single metastasis were included. Studies had high heterogeneity. Multiple significant variables affecting the outcome were signalized. Meta-analysis showed no significant differences for survival (HR, 1.10; 95% CI, 0.75-1.45) or LR (HR, 0.81; 95% CI, 0.42-1.20). CONCLUSIONS: According to current evidence, in patients with a single small metastasis there is no statistically significant difference in OS or LR among the chosen techniques (SR or SRS). Multiple significant co-variables may affect both outcomes. Different outcomes better than OS should be evaluated in further randomized studies.

Association of ABO and Rh blood groups with obstetric outcomes in SARS-CoV-2 infected pregnancies: A prospective study with a multivariate analysis.

OBJECTIVE: To evaluate the influence of ABO and Rh blood groups on morbidity among SARS-CoV-2 infected pregnancies. DESIGN: Prospective observational study. SETTING: 78 centers of the Spanish Obstetric Emergency Group. POPULATION: Pregnant women with SARS-CoV-2 tested with polymerase-chain-reaction between 26-February and 5-November 2020. A cohort of 1278 SARS-CoV-2(+) pregnant women was analyzed and a concurrent comparison group of 1453 SARS-COV-2(-) patients was established. METHODS: Data were collected from medical charts. SARS-COV-2(+) was compared with SARS-COV-2(-) for differences in distribution of blood groups. We performed multivariate analysis, controlling for maternal age and ethnicity, to evaluate association of ABO and Rh blood groups with maternal and perinatal outcomes in SARS-CoV-2(+) patients with adjusted odds ratios (aOR) and 95% confidence intervals (CI). MAIN OUTCOMES MEASURES: Medical morbidity: Symptomatic COVID-19 and medical complications. Obstetric outcomes: caesarean delivery, preterm deliveries, preterm premature rupture of membranes (PPROM), hemorrhagic events, pre-eclampsia, maternal and neonatal mortality, stillbirth. RESULTS: Differences were noted between blood types and Rh for age and ethnicity comparing SARS-CoV-2(+) and SARS-CoV-2(-) groups (p < 0.05). Among the SARS-CoV-2(+) cohort, the odds of symptomatic COVID-19 and obstetric hemorrhagic event were higher in Rh+ vs Rh- mothers (aOR 1.48, 95% CI 1.02-2.14, p = 0.037, and aOR 8.72, 95% CI 1.20-63.57, p = 0.033, respectively), and PPROM were higher among blood type A vs non-A mothers (aOR 2.06, 95% CI 1.01-4.18, p = 0.046). CONCLUSIONS: In SARS-CoV-2(+) pregnant women, Rh- status was associated with a lower risk of symptomatic COVID-19, while Rh+ and blood group A were associated with obstetric hemorrhage and PPROM, respectively.

Metabolic syndrome and male fertility disorders: Is there a causal link?

Infertility is a global health problem affecting 10-15% of couples in reproductive age. Recent studies have provided growing evidence supporting that lifestyle factors can affect male fertility through alterations in endocrine profiles, spermatogenesis and/or sperm function. One of these critical factors could be the change in the food intake behavior in modern societies that produces metabolic alterations. Regarding this, metabolic syndrome (MetS) prevalence has increased in epidemic in the last 40-50 years. Although MetS is associated with advanced age, changes in lifestyles have accelerated the appearance of symptoms in the reproductive age. We review herein the current understanding of the relationship between MetS and the male reproductive status. For this purpose, in this narrative review a comprehensive literature search was made in both animal models and men, allowing us to evaluate such relationship. This analysis showed a high variability in the reproductive phenotypes observed in patients and mice suffering MetS, including sperm parameters, fertility and offspring health. In view of this, we proposed that the reproductive effects, which are diverse and not robust, observed among MetS-affected males, might depend on additional factors not associated with the metabolic condition and contributed not only by the affected male but also by his partner. With this perspective, this review provides a more accurate insight of this syndrome critical for the identification of specific diagnostic indicators and treatment of MetS-induced fertility disorders.

A Novel Method Based on Headspace-Ion Mobility Spectrometry for the Detection and Discrimination of Different Petroleum Derived Products in Seawater.

The objective of the present study is to develop an optimized method where headspace-ion mobility spectrometry is applied for the detection and discrimination between four petroleum-derived products (PDPs) in water. A Box-Behnken design with a response surface methodology was used, and five variables (incubation temperature, incubation time, agitation, sample volume, and injection volume) with influences on the ion mobility spectrometry (IMS) response were optimized. An IMS detector was used as a multiple sensor device, in which, each drift time acts as a specific sensor. In this way, the total intensity at each drift time is equivalent to multiple sensor signals. According to our results, 2.5 mL of sample incubated for 5 min at 31 °C, agitated at 750 rpm, and with an injection volume of 0.91 mL were the optimal conditions for successful detection and discrimination of the PDPs. The developed method has exhibited good intermediate precision and repeatability with a coefficient of variation lower than 5%, (RSD (Relative Standard Deviation): 2.35% and 3.09%, respectively). Subsequently, the method was applied in the context of the detection and discrimination of petroleum-derived products added to water samples at low concentration levels (2 µL·L-1). Finally, the new method was applied to determine the presence of petroleum-derived products in seawater samples.

Direct Medical Costs, Productivity Loss Costs and Out-Of-Pocket Expenditures in Women with Breast Cancer in Latin America and the Caribbean: A Systematic Review.

OBJECTIVE: Our objective was to conduct a systematic review of the literature to identify, categorise, assess, and synthesise the healthcare costs of patients with breast cancer (BC) and their relatives in Latin America and the Caribbean (LAC). METHODS: In December 2020, we searched for published data in PubMed, LILACS, EMBASE, and other sources, including the grey literature. Studies were eligible if they were conducted in LAC and reported the direct medical costs, productivity loss costs, out-of-pocket expenditure, and other costs to patients with BC and their relatives. No restrictions were imposed on the type of BC population (metastatic BC or human epidermal growth factor receptor 2-positive/negative BC, among others). We summarised the characteristics and methodological approach of each study and the healthcare costs by cancer stage. We also developed and applied an original ad hoc instrument to assess the quality of the cost estimation studies. RESULTS: We identified 2725 references and 63 included studies. In total, 79.3% of the studies solely reported direct medical costs and five solely reported costs to patients and their relatives. Only 14.3% of the studies were classified as of high quality. The pooled weighted average direct medical cost per patient-year (year 2020 international dollars [I$]) by BC stage was I$13,179 for stage I, I$15,556 for stage II, I$23,444 for stage III, and I$28,910 for stage IV. CONCLUSION: This review provides the first synthesis of BC costs in LAC. Our findings show few high-quality costing studies in BC and a gap in the literature measuring costs to patients and their relatives. The high costs associated with the advanced stages of BC call into question the affordability of treatments and their accessibility for patients. Registered in PROSPERO (CRD42018106835).
