Estimating the cost of HIV services for key populations provided by the LINKAGES program in Kenya and Malawi.

BACKGROUND: Data remain scarce on the costs of HIV services for key populations (KPs). The objective of this study was to bridge this gap in the literature by estimating the unit costs of HIV services delivered to KPs in the LINKAGES program in Kenya and Malawi. We estimated the mean total unit costs of seven clinical services: post-exposure prophylaxis (PEP), pre-exposure prophylaxis (PrEP), HIV testing services (HTS), antiretroviral therapy (ART), sexually transmitted infection (STI) services, sexual and reproductive health (SRH) services, and management of sexual violence (MSV). These costs take into account the costs of non-clinical services delivered alongside clinical services and the pre-service and above-service program management integral to the LINKAGES program. METHODS: Data were collected at all implementation levels of the LINKAGES program including 30 drop-in-centers (DICs) in Kenya and 15 in Malawi. This study was conducted from the provider's perspective. We estimated economic costs for FY 2019 and cost estimates include start-up costs. Start-up and capital costs were annualized using a discount rate of 3%. We used a combination of top-down and bottom-up costing approaches. Top-down methods were used to estimate the costs of headquarters, country offices, and implementing partners. Bottom-up micro-costing methods were used to measure the quantities and prices of inputs used to produce services in DICs. Volume-weighted mean unit costs were calculated for each clinical service. Costs are presented in 2019 United States dollars (US$). RESULTS: The mean total unit costs per service ranged from US$18 (95% CI: 16, 21) for STI services to US$635 (95% CI: 484, 785) for PrEP in Kenya and from US$41 (95% CI: 37, 44) for STI services to US$1,240 (95% CI 1156, 1324) for MSV in Malawi. Clinical costs accounted for between 21 and 59% of total mean unit costs in Kenya, and between 25 and 38% in Malawi. Indirect costs-including start-up activities, the costs of KP interventions implemented alongside clinical services, and program management and data monitoring-made up the remaining costs incurred. CONCLUSIONS: A better understanding of the cost of HIV services is highly relevant for budgeting and planning purposes and for optimizing HIV services. When considering all service delivery costs of a comprehensive HIV service package for KPs, costs of services can be significantly higher than when considering direct clinical service costs alone. These estimates can inform investment cases, strategic plans and other budgeting exercises.

Intoxicación infantil por plomo en México: otras fuentes de exposición más allá del barro vidriado (Ensanut 2022).

OBJETIVO: Describir y actualizar al año 2022 la prevalencia de intoxicación por plomo (Pb) en la población infantil de 1-4 años en México y describir fuentes de exposición ambiental, paraocupacional y uso de barro vidriado (BV). Material y métodos. Estudio en una muestra de menores que participaron en la Encuesta Nacional de Salud y Nutrición 2022 (Ensanut 2022). Se midió la concentración de plomo en sangre (PbS) capilar. Se aplicó un cuestionario para indagar sobre fuentes de exposición a Pb. RESULTADOS: Se midió PbS en 1 158 menores de 1-4 años. La prevalencia nacional de intoxicación por Pb (≥5.0 µg/dL) fue 16.8% (IC95%:13.6,20.5). La proporción de hogares que reportó exposición a una fuente exclusiva fue de 21.2, 17.7 y 7.4% para BV, exposición ambiental y paraocupacional, respectivamente. La prevalencia de intoxicación de los expuestos a una sola fuente fue 21.5%, y esta cifra aumenta a 24.2% entre quienes reportaron exposición combinada tres tipos de fuentes. Conclusión. La prevalencia nacional de intoxicación por plomo permaneció estable con respecto a lo reportado en la Ensanut 2018-19. El uso de BV es una fuente de exposición relevante, pero no es la única. Se identificó una contribución importante por exposición ambiental y, en menor medida, de exposición paraocupacional.

Contribución de diversas fuentes de exposición a la concentración de plomo en sangre en población infantil mexicana, Ensanut 2022.

OBJETIVO: Analizar la asociación entre fuentes de exposición al plomo (FEPb) y la concentración en sangre capilar (PbS) en menores de 1 a 4 años de edad a nivel nacional y regional, así como cuantificar la contribución relativa de las distintas FEPb. Material y métodos. Se utilizaron datos de la Encuesta Nacional de Salud y Nutrición (Ensanut 2022). Las FEPb consideradas fueron uso de loza de barro vidriada con plomo (LBVPb), residencia cercana a sitios contaminados y exposición paraocupacional. Se estimaron prevalencias de intoxicación (PbS ≥ 5.0 mg/dL) y medias geométricas de PbS. Se utilizaron modelos de regresión para PbS (escala logarítmica) y la descomposición Shapley-Owen de R2 para evaluar la contribución relativa de cada FEPb. RESULTADOS: Las FEPb estudiadas explican el 6% de la variabilidad de PbS a nivel nacional; de este, el 87.3% lo explica el uso de LBVPb, el 4.2% otras FEPb ambiental y 1.3% FEPb paraocupacionales. La contribución relativa del uso de LBVPb varía entre regiones, desde 38.1 a 76.8%. Algunas regiones destacan la FEPb ambiental, pero no paraocupacional. CONCLUSIONES: Los resultados confirman que el uso de LBVPb es la principal fuente de exposición reportada y sugieren que la población no identifica las principales FEPb documentadas hasta ahora.

Psoriatic arthritis in patients with psoriasis: A clinical-epidemiological study at a dermatology center in western Mexico.

BACKGROUND/OBJECTIVE: Psoriatic arthritis (PsA) is a chronic inflammatory illness. Approximately, 15% of psoriasis patients have undiagnosed PsA. In Mexico, we found no related studies. Our objective was to investigate the clinical-epidemiological characteristics of PsA in psoriasis patients in western Mexico. METHODS: A cross-sectional study including Mexican patients with clinical and histopathological diagnosis of psoriasis. Physical examination, rheumatoid factor analysis and radiographies of axial and peripheral skeleton were performed. The prevalence of PsA using the CASPAR criteria, age, sex; clinical variants of PsA, psoriasis type and the Psoriasis Area and Severity Index (PASI), were assessed. Descriptive and inferential statistics were used. RESULTS: Of 90 patients with psoriasis, 48 met the criteria for PsA, with a prevalence of 53%, and average age of 50 ± 15 years. Predominating were, the female sex in 29 (60%), the axial variant of PsA in 24 (50%), and psoriasis plaques in 40 (83%). The average PASI was 12 ± 11. All cases were rheumatoid factor negative. These variables were not significantly different when comparing subjects with and without PsA, except for the female sex (60% vs. 7%; P < 0.001). CONCLUSIONS: Patients with psoriasis should intentionally be evaluated jointly Dermatologists and Rheumatologists searching joint involvement given the high prevalence of PsA previously undiagnosed.

Ex post adjustment for measurement error in stunting calculations: an illustration from Egypt.

OBJECTIVE: The present study provides ranges for the magnitude of bias caused by measurement error in stunting rates, a widely used a proxy for long-term nutritional status. DESIGN: Stunting, which is determined by the number of cases that fall below -2 sd from the mean height-for-age in the population, mechanically increases with higher variance. This variance stems from both natural heterogeneity in the population and measurement error. To isolate the effect of measurement error, we model the true distributions which could give rise to the observed distributions after subtracting a simulated measurement error. SETTING: We analyse information from three rounds of the Demographic and Health Survey (DHS) in Egypt (2005, 2008 and 2014). Egypt ranks high among developing countries with low-quality anthropometric data collected in the DHS, currently the main source of anthropometry in the country. PARTICIPANTS: The study relies on re-analysis of existing DHS data, which record height, weight and age data for children under 5 years old. RESULTS: Under the most conservative assumptions about measurement error, the stunting rate falls by 4 percentage points for the most recent DHS round, while assuming higher levels of measurement error reduces the stunting rate more dramatically. CONCLUSIONS: Researchers should be aware of and adjust for data quality concerns in calculating stunting rates for cross-survey comparisons or in communicating to policy makers.

[Increase in medical offices in pharmacies in Mexico and health care in public healthservices between 2012 and 2018]. / Aumento en la oferta de consultorios adyacentes a farmacias y atenciónen servicios públicos en Méxicoentre 2012 y 2018.

OBJECTIVE: To study changes in health care utilization in the public and private sector in Mexico in 2012 and 2018. MATERIALS AND METHODS: We used the 2012 and 2018-19 National Health and Nutrition Surveys and aggregated data on the supply of health services. RESULTS: There was an acceler-ated increase in medical offices in pharmacies (MOP) that was related to a lower use of public health services, even among the population with social security. We found that individu-als living in municipalities with a high density of MOP had a lower probability of using public services. The increase in the affiliation to the Seguro Popular (SP) was not followed by an increase in public health services and was not associated with a higher utilization of public health services. CONCLUSIONS: Affiliation or health insurance does not guarantee access to public services. Given the high increase in MOP, it is urgent to design and evaluate strategies to regulate their performance.

OBJETIVO: Estudiar los cambios en la utilización de servicios de salud públicos y privados en México entre 2012 y 2018. MATERIAL Y MÉTODOS: Usamos la Encuesta Nacional de Salud y Nutrición de los años 2012 y 2018 (Ensanut 2012 y Ensanut 2018-19), y datos agregados de la oferta de servicios de salud. RESULTADOS: Los consultorios adyacentes a farma-cias (CAF) crecieron aceleradamente y esto se relacionó con un menor uso de servicios públicos, aun en la población con seguridad social. Individuos que viven en municipios con alta densidad de CAF tienen menor probabilidad de usar servicios públicos. El aumento en la afiliación al Seguro Popular (SP) no se acompañó de un incremento de la oferta de servicios públicos y no se relaciona con mayor utilización de servicios públicos. CONCLUSIONES: Derechohabiencia y afiliación no garantizan el acceso a la atención médica en servicios públicos. Dada la creciente importancia de los CAF, es urgente diseñar y evaluar estrategias para regular su desempeño.

Nutritional training in a humanitarian context: Evidence from a cluster randomized trial.

Behavioural change communication interventions have been shown to be effective at improving infant and young child nutrition knowledge and practices. However, evidence in humanitarian response contexts is scarce. Using data on secondary outcomes of breastfeeding, water treatment, and knowledge from a cluster randomized control trial of the Yemen Cash for Nutrition programme's impact on child nutritional status, this paper shows that the programme significantly improved knowledge and practices for poor women with young children in the pilot districts. The intervention consisted of cash transfers and monthly group nutrition education sessions led by locally recruited community health volunteers. Data are based on self-reports by participants. Estimating impacts among all 1,945 women in 190 clusters randomly assigned to treatment versus control and controlling for baseline levels and community characteristic and adjusting for noncompliance with randomization, the programme increased the probability of breastfeeding initiation within the first hour after delivery by 15.6% points (p < .05; control = 74.4% and treatment = 83.6%), the probability of exclusive breastfeeding during the first 6 months by 14.4% points (control = 13.5% and treatment = 25.3%), the probability of households treating water consumed by adults by 16.7% points (p < .01; control = 13.9% and treatment = 23.4%), and treating water consumed by children under two by 10.3% points (p < .10; control = 31.2% and treatment = 37.9%). Impacts on knowledge and breastfeeding are similar for both literate and illiterate women, and water treatment impacts are significantly larger for literate women. This study was registered at 3ie (RIDIE-STUDY-ID-5b4eff881b29a) and funded by the Nordic Trust Fund and Consultative Group on International Agricultural Research programme on Policies, Institutions, and Markets.

A surge in food insecurity during the COVID-19 pandemic in a cohort in Mexico City.

BACKGROUND: The COVID-19 pandemic has not only caused tremendous loss of life and health but has also greatly disrupted the world economy. The impact of this disruption has been especially harsh in urban settings of developing countries. We estimated the impact of the pandemic on the occurrence of food insecurity in a cohort of women living in Mexico City, and the socioeconomic characteristics associated with food insecurity severity. METHODS: We analyzed data longitudinally from 685 women in the Mexico City-based ELEMENT cohort. Food insecurity at the household level was gathered using the Latin American and Caribbean Food Security Scale and measured in-person during 2015 to 2019 before the pandemic and by telephone during 2020-2021, in the midst of the pandemic. Fluctuations in the average of food insecurity as a function of calendar time were modeled using kernel-weighted local polynomial regression. Fixed and random-effects ordinal logistic regression models of food insecurity were fitted, with timing of data collection (pre-pandemic vs. during pandemic) as the main predictor. RESULTS: Food insecurity (at any level) increased from 41.6% during the pre-pandemic period to 53.8% in the pandemic stage. This increase was higher in the combined severe-moderate food insecurity levels: from 1.6% pre-pandemic to 16.8% during the pandemic. The odds of severe food insecurity were 3.4 times higher during the pandemic relative to pre-pandemic levels (p<0.01). Socioeconomic status quintile (Q) was significantly related to food insecurity (Q2 OR = 0.35 p<0.1, Q3 OR = 0.48 p = 0.014, Q4 OR = 0.24 p<0.01, and Q5 OR = 0.17 p<0.01), as well as lack of access to social security (OR = 1.69, p = 0.01), and schooling (OR = 0.37, p<0.01). CONCLUSIONS: Food insecurity increased in Mexico City households in the ELEMENT cohort as a result of the COVID-19 pandemic. These results contribute to the body of evidence suggesting that governments should implement well-designed, focalized programs in the context of economic crisis such as the one caused by COVID-19 to prevent families from the expected adverse health and well-being consequences associated to food insecurity, especially for the most vulnerable.

Ab Initio Calculations of Chitosan Effects on the Electronic Properties of Unpassivated Triangular ZnO Nanowires Oriented along [0001] Directions.

In recent years, both chitosan and ZnO nanostructures have been identified as potential antibacterial substances; however, the potential applications of chitosan adsorbed on ZnO nanowires have not been explored and could offer exciting new perspectives for both materials, for example, in biocompatible electronic circuits. In this work, we investigate the effect of chitosan on the electronic properties of triangular ZnO nanowires (ZnO NWs) from a theoretical perspective. All calculations were performed using density functional theory within the generalized gradient approximation. We considered six different positions of the chitosan molecule (CS) on the nanowire surface. We varied the amine position of CS, viewing it parallel, perpendicular, and at a 45° angle with respect to the NW axis. Our results show that all configurations are chemically stable; moreover, the interaction of the NW surface with the OH radical of CS creates flat states within the band gap energy of the ZnO NWs that might resemble p-doping. In addition, these states induce changes in the band gap energy of the ZnO NWs. All NWs show high chemical stability regardless of the CS position; hence, the adsorption results of all NW assemblies appear to be chemically favorable.

The Cost of Providing Comprehensive HIV Services to Key Populations: An Analysis of the LINKAGES Program in Kenya and Malawi.

INTRODUCTION: Timely data on HIV service costs are critical for estimating resource needs and allocating funding, but few data exist on the cost of HIV services for key populations (KPs) at higher risk of HIV infection in low- and middle-income countries. We aimed to estimate the total and per contact annual cost of providing comprehensive HIV services to KPs to inform planning and budgeting decisions. METHODS: We collected cost data from the Linkages across the Continuum of HIV Services for Key Populations Affected by HIV (LINKAGES) program in Kenya and Malawi serving female and male sex workers, men who have sex with men, and transgender women. Data were collected prospectively for fiscal year (FY) 2019 and retrospectively for start-up activities conducted in FY2015 and FY2016. Data to estimate economic costs from the provider's perspective were collected from LINKAGES headquarters, country offices, implementing partners (IPs), and drop-in centers (DICs). We used top-down and bottom-up cost estimation approaches. RESULTS: Total economic costs for FY2019 were US$6,175,960 in Kenya and US$4,261,207 in Malawi. The proportion of costs incurred in IPs and DICs was 66% in Kenya and 42% in Malawi. The costliest program areas were clinical services, management, peer outreach, and monitoring and data use. Mean cost per contact was US$127 in Kenya and US$279 in Malawi, with a mean cost per contact in DICs and IPs of US$63 in Kenya and US$104 in Malawi. CONCLUSION: Actions undertaken above the service level in headquarters and country offices along with those conducted below the service level in communities, comprised important proportions of KP HIV service costs. The costs of pre-service population mapping and size estimation activities were not negligible. Costing studies that focus on the service level alone are likely to underestimate the costs of delivering HIV services to KPs.

Reproductive performance of the Mesa silverside (Chirostoma jordani Woolman, 1894) under natural and controlled photoperiods.

Chirostoma jordani is a native annual species inhabiting lacustrine waters of the Central Mexico Plateau. It is widely distributed and is currently facing high environmental pressures. Five experiments were performed to study the reproductive performance of this species. Four of the experiments were conducted in 270-L indoor recirculation tanks. Two males and one female at the first stage of reproduction were included in each test. A photoperiod of 14 light hours and 10 dark hours was used. In a fifth experiment, 10 females and 15 males were kept in an outdoor 3,000-L recirculation tank under natural photoperiod. The number of spawns, fertilised eggs and 30-day-old juveniles were counted and the survival rate was calculated. The results indicated significant differences (P < 0.05) between treatments. Higher spawn numbers and greater egg production were observed under controlled photoperiod, and higher numbers of juveniles and a higher survival rate were observed under natural photoperiod. The trials exhibited different patterns of egg production during the experiment. The egg production in the natural-photoperiod trials followed a polynomial curve model. In contrast, the trials under the controlled photoperiod showed an irregular pattern of increases and decreases in egg production.

Effects of salinity on growth and survival in five Artemia franciscana (Anostraca: Artemiidae) populations from Mexico Pacific Coast.

Salinity is an important factor influencing growth and survival of aquatic organisms such as Artemia, a valuable aquaculture species. This study evaluated the effects of salinity on A. franciscana populations from different water bodies in Mexico's Pacific Coast. With this purpose, five autochthonous bisexual Artemia populations were tested to assess their survival and growth values against salinities of 40, 60, 80, 100 and 120 g/l, under laboratory conditions (25 +/- 2 degrees C; pH 8-10; constant light and aeration). The organisms were fed with 100 mL of rice bran and 2L of Tetraselmis suecica (500 000 cel/ml). The culture experiments were made in 200L plastic tanks, and survival and growth final values were obtained after 21 culture days. Survival and growth curves were determined by a regression analysis (R2). The significant differences between salinities were determined by ANOVA test (p < 0.05). The best survival and growth rates were found at salinities of 100-120 g/l. When the Mexican Artemia populations were cultivated at 40 g/l of salinity, 100% mortality was observed in the juvenile stage. This study determined that survival and growth values of A. franciscana populations increased with salinity. The five A. franciscana populations presented significant differences in their survival rate under various salinity regimes. The studied populations experienced high mortality at salinities under 60 g/l and over 200 g/l, and especially during the metanauplius stage. The present study confirms that growth rates in Mexican A. franciscana populations from Pacific Coast habitats are not inversely proportional to salinity. These A. franciscana populations should be cultured at 100-120 g/l of salinity to obtain better survival and growth rates. This data is useful to improve culture systems in aquaculture biomass production systems.

Association between density of stores and purchases of ultra-processed food and sugar-sweetened beverages in Mexico.

In Mexico, purchases of ultra-processed food and sugar-sweetened beverages (SSB) and the number of large supermarkets, discount and convenience stores are growing. The objective of this study was to analyze the association between the density of different types of food stores and ultra-processed food and SSB (taxed beverages) purchases in a representative sample of Mexican households. Results show that the density of convenience stores (national and in urban areas) was significantly associated with higher purchases of ultra-processed food and that supermarkets were marginally associated. Our findings are stronger for beverages where we found that convenience stores, discount stores, small grocery stores and stores speciliazed in selling candies, popsicles, soft drinks and other food were associated with higher purchases of taxed beverages. Mexico should implement or strengthen current policies to reduce purchases of ultra-processed food and sugar-sweetened beverages and to regulate the location and density of stores.

Update of the Mexican College of Rheumatology Guidelines for the Pharmacological Treatment of Rheumatoid Arthritis, 2018. / Actualización de las guías del tratamiento farmacológico de la artritis reumatoide del Colegio Mexicano de Reumatología 2018.

Therapeutic advances in rheumatoid arthritis require periodic review of treatment guidelines. OBJECTIVE: To update the Mexican College of Rheumatology guidelines on the pharmacological treatment of rheumatoid arthritis. METHOD: Board certified rheumatologists from different health institutions and regions of the country participated. Work teams were formed that reviewed the previous guidelines, elaborated new questions, reviewed the literature, and scored the evidence that was presented and discussed in plenary session. The conclusions were presented to infectologists, gynaecologists and patients. Recommendations were based on levels of evidence according to GRADE methodology. RESULTS: Updated recommendations on the use of available medications for rheumatoid arthritis treatment in Mexico up to 2017 are presented. The importance of adequate and sustained control of the disease is emphasized and relevant safety aspects are described. Bioethical conflicts are included, and government action is invited to strengthen correct treatment of the disease. CONCLUSIONS: The updated recommendations of the Mexican College of Rheumatology on the pharmacological treatment of rheumatoid arthritis incorporate the best available information to be used in the Mexican health care system.

Enhancing the energy spectrum of graphene quantum dot with external magnetic and Aharonov-Bohm flux fields.

In this paper, we have to apply the Dirac-Weyl equation to find the analytical energy eigenvalues of the graphene quantum dot interacting in the presence of AB-flux field and external magnetic field. We find that the energy eigenvalue of the graphene quantum dot decreases with both magnetic and AB-flux field but the effect of AB-flux field is more dominant. By ameliorating the intensity of the AB-flux field and keeping the magnetic field constant, the quantum-dot states entangled to produce Landau Levels. We show that besides using the graphene sheet and external magnetic field, the Aharonov-Bohm AB-flux field could as well be used to manipulate the carriers state energies in graphene.

Clinical practice guidelines for the treatment of systemic lupus erythematosus by the Mexican College of Rheumatology. / Guía de práctica clínica para el manejo del lupus eritematoso sistémico propuesta por el Colegio Mexicano de Reumatología.

There are national and international clinical practice guidelines for systemic lupus erythematosus treatment. Nonetheless, most of them are not designed for the Mexican population or are devoted only to the treatment of certain disease manifestations, like lupus nephritis, or are designed for some physiological state like pregnancy. The Mexican College of Rheumatology aimed to create clinical practice guidelines that included the majority of the manifestations of systemic lupus erythematosus, and also incorporated guidelines in controversial situations like vaccination and the perioperative period. The present document introduces the «Clinical Practice Guidelines for the Treatment of Systemic Lupus Erythematosus¼ proposed by the Mexican College of Rheumatology, which could be useful mostly for non-rheumatologist physicians who need to treat patients with systemic lupus erythematosus without having the appropriate training in the field of rheumatology. In these guidelines, the reader will find recommendations on the management of general, articular, kidney, cardiovascular, pulmonary, neurological, hematologic and gastrointestinal manifestations, and recommendations on vaccination and treatment management during the perioperative period.

Recurrent postinfectious glomerulonephritis: an unusual evolution compatible with C3 glomerulopathy.

Acute endocapillary glomerulonephritis, as its name suggests, is a one-time process, which usually resolves within weeks. However, in a small percentage of patients, the disease becomes chronic. In these cases, a deregulation in the alternative complement pathway, which can be caused by mutations or autoantibodies, has been proposed as a pathophysiological mechanism. As a result, the alternative complement pathway remains active after resolution of infection. We report a patient with two episodes of acute renal failure, both times diagnosed by renal biopsy of acute endocapillary glomerulonephritis, with slow recovery after two episodes of low-serum complement C3, haematuria and proteinuria.

Abstract: Objective. To study changes in health care utilization in the public and private sector in Mexico in 2012 and 2018. Material and methods: We used the 2012 and 2018-19 National Health and Nutrition Surveys and aggregated data on the supply of health services. Results. There was an accelerated increase in medical offices in pharmacies (MOP) that was related to a lower use of public health services, even among the population with social security. We found that individuals living in municipalities with a high density of MOP had a lower probability of using public services. The increase in the affiliation to the Seguro Popular (SP) was not followed by an increase in public health services and was not associated with a higher utilization of public health services. Conclusions. Affiliation or health insurance does not guarantee access to public services. Given the high increase in MOP, it is urgent to design and evaluate strategies to regulate their performance.

Clinical practice guidelines for the management of pregnancy in women with autoimmune rheumatic diseases of the Mexican College of Rheumatology. Part I.

BACKGROUND: Pregnancy in women with autoimmune rheumatic diseases is associated with several maternal and fetal complications. The development of clinical practice guidelines with the best available scientific evidence may help standardize the care of these patients. OBJECTIVES: To provide recommendations regarding prenatal care, treatment, and a more effective monitoring of pregnancy in women with lupus erythematosus (SLE), rheumatoid arthritis (RA) and antiphospholipid antibody syndrome (APS). METHODOLOGY: Nominal panels were formed for consensus, systematic search of information, development of clinical questions, processing and grading of recommendations, internal validation by peers, and external validation of the final document. The quality criteria of the AGREE II instrument were followed. RESULTS: The various panels answered the 37 questions related to maternal and fetal care in SLE, RA, and APS, as well as to the use of antirheumatic drugs during pregnancy and lactation. The recommendations were discussed and integrated into a final manuscript. Finally, the corresponding algorithms were developed. We present the recommendations for pregnant women with SLE in this first part. CONCLUSIONS: We believe that the Mexican clinical practice guidelines for the management of pregnancy in women with SLE integrate the best available evidence for the treatment and follow-up of patients with these conditions.
