RESUMO
STUDY QUESTION: In lesbian couples, is shared motherhood IVF (SMI) associated with an increase in perinatal complications compared with artificial insemination with donor sperm (AID)? SUMMARY ANSWER: Singleton pregnancies in SMI and AID had very similar outcomes, except for a non-significant increase in the rate of preeclampsia/hypertension (PE/HT) in SMI (recipient's age-adjusted odds ratio (OR) = 1.9, 95% CI = 0.7-5.2; P = 0.19), but twin SMI pregnancies had a much higher frequency of PE/HT than AID twins (recipient's age-adjusted OR = 21.7, 95% CI = 2.8-289.4; P = 0.01). WHAT IS KNOWN ALREADY: Oocyte donation (OD) pregnancies are associated with an increase in perinatal complications, in particular, preterm delivery and low birth weight, and PE/HT. However, it is unclear to what extent these complications are due to OD process or to the conditions why OD was performed, such as advanced age and underlying health conditions. Unfortunately, the literature concerning perinatal outcomes in SMI is scarce. STUDY DESIGN, SIZE, DURATION: Retrospective study involving 660 SMI cycles (299 pregnancies) and 4349 AID cycles (949 pregnancies) assisted over a 10-year period. PARTICIPANTS/MATERIALS, SETTING, METHODS: All cycles fulfilling the inclusion criteria performed in lesbian couples seeking fertility treatment in 17 Spanish clinics of the same group. Pregnancy rates of SMI and AID cycles were compared. Perinatal outcomes were compared: gestational length, newborn weight, preterm and low birth rates, PE/HT rates, cesarean section rates, perinatal mortality, and newborn malformations. MAIN RESULTS AND THE ROLE OF CHANCE: Pregnancy rates were higher in SMI than in AID (45.3% versus 21.8%, P < 0.001). There was a non-significant trend to higher multiple rate in AID (4.7% versus 8.5%, P = 0.08). In single pregnancies, there were no differences between SMI and AID in gestational age (278 days (268-285) versus 279 (272-284), P = 0.24), preterm rate (8.3% versus 7.3%, P = 0.80), preterm <28 weeks (0.6% versus 0.4%, P = 1.00), newborn weight (3195 g (2915-3620) versus 3270 g (2980-3600), P = 0.296), low birth rate (6.4% versus 6.4%, P = 1.00), extremely low birth weight (0.6% versus 0.5%, P = 1.00), and the distribution of newborns by weight groups. Cesarean section rate, newborn malformation rate, and perinatal mortality were also similar in SMI and AID. Additionally, there was non-significant trend in hypertensive disorders to an increase in PE/HT among SMI (recipient's age-adjusted OR = 1.9, 95% CI = 0.7-5.2). Overall, perinatal data are consistent with what is reported in the general population. In twin pregnancies, the aforementioned perinatal parameters were also very similar in SMI and AID. However, SMI twin pregnancies had a very high risk of PE/HT when compared with AID (recipient's age-adjusted OR = 21.7, 95% CI = 2.8-289.4, P = 0.01). LIMITATIONS, REASONS FOR CAUTION: Our data regarding the pregnancy course were obtained from information registered in the delivery report as well as from what was reported by the patients themselves, so a certain degree of inaccuracy cannot be ruled out. Additionally, in some parameters, there was up to 10% of data missing. However, since the methodology of reporting was the same in SMI and AID groups, one should not expect a differential reporting bias. It cannot be ruled out that the risk of PE/HT in simple gestations would be significant in a larger study. Additionally, in the SMI group allocation to the transfer of 2 embryos was not randomized so some bias is possible. WIDER IMPLICATIONS OF THE FINDINGS: SMI, if single embryo transfer is performed, seems to be is a safe procedure. Double embryo transfer should not be performed in SMI. Our data suggest that the majority of complications in OD could be related more with recipient status than with OD itself, since with SMI (performed in women without fertility problems) the perinatal complications were much lower than usually described in OD. STUDY FUNDING/COMPETING INTEREST(S): No external funding was received. The authors declare that they have no conflict of interest. TRIAL REGISTRATION NUMBER: N/A.

AIM: Growth differentiation factor 15 (GDF15) is a stress response cytokine that has been proposed as a relevant metabolic hormone. Descriptive studies have shown that plasma GDF15 levels are regulated by short term changes in nutritional status, such as fasting, or in obesity. However, few data exist regarding how GDF15 levels are regulated in peripheral tissues. The aim of the present work was to study the variations on gastric levels of GDF15 and its precursor under different physiological conditions, such as short-term changes in nutritional status or overfeeding achieved by HFD. Moreover, we also address the sex- and age-dependent alterations in GDF15 physiology. METHODS: The levels of gastric and plasma GDF15 and its precursor were measured in lean and obese mice, rats and humans by western blot, RT-PCR, ELISA, immunohistochemistry and by an in vitro organ culture system. RESULTS: Our results show a robust regulation of gastric GDF15 production by fasting in rodents. In obesity an increase in GDF15 secretion from the stomach is reflected with an increase in circulating levels of GDF15 in rats and humans. Moreover, gastric GDF15 levels increase with age in both rats and humans. Finally, gastric GDF15 levels display sexual dimorphism, which could explain the difference in circulating GFD15 levels between males and females, observed in both humans and rodents. CONCLUSIONS: Our results provide clear evidence that gastric GDF15 is a critical contributor of circulating GDF15 levels and can explain some of the metabolic effects induced by GDF15.
RESUMO
Acne fulminans is a severe and rare form of inflammatory acne. Lesion severity and subsequent scarring has a negative impact on the patient's quality of life. We conducted a narrative review of the literature on acne fulminans based on a search for relevant English- and Spanish-language articles published in Medline. We included case reports and case series. The main aim was to describe the clinical and demographic characteristics of patients with acne fulminans. A secondary aim was to determine whether quality of life was affected by the site or extent of lesions. We reviewed 91 articles describing 212 cases of acne fulminans. The mean age of the patients (91.94% male) was 16.6 years. A personal and family history of acne vulgaris was reported for 97.63% and 54.90% of patients, respectively. A trigger was identified in 44.79% of cases. The main cause was pharmacologic (96.63%) and the main drug isotretinoin (65.28%). The sites most often affected were the face (89.31%), the posterior trunk (77.86%), and the anterior trunk (74.81%). The predominant disease subtype was acne fulminans with systemic symptoms (59.12%), which were mostly general (97.06%). Systemic corticosteroids were the most widely used treatment (81.03%). The impact of the disease on quality of life was reported for two patients. In conclusion, acne fulminans mainly affects the face and trunk of male adolescents with a history of acne vulgaris. The main subtype was acne fulminans with systemic symptoms, and most patients were treated with systemic corticosteroids. The effect of acne fulminans on quality of life is under-reported.

OBJECTIVES: To determine the usefulness of the in vitro and in vivo methods used in the diagnosis of kiwifruit allergy and to specifically assess the impact of seed proteins on sensitivity. METHODS: We performed skin prick tests (SPTs) using various commercial extracts, homemade pulp, and seed extracts and prick-prick tests with kiwifruit on 36 allergic patients. The presence of specific IgE (sIgE) was assessed using the ImmunoCAP (kiwifruit extract), ELISA (Act d 1, Act d 2), ISAC, and FABER assays. Immunoblotting of seed extract was carried out, and a single-blind oral food challenge was performed with whole seeds in seed-sensitized individuals. RESULTS: The prick prick test with kiwifruit demonstrated the highest diagnostic capacity (81.8% sensitivity and 94.1% specificity) among the in vivo tests. The sIgE levels measured using ImmunoCAP (kiwifruit extract) showed a similar sensitivity to that of global ISAC and FABER (63.9%, 59.5%, and 58.3%, respectively). Act d 1 was the major allergen. Sensitization to Act d 1 was associated with positive sIgE results to whole kiwifruit extract detected by ImmunoCAP (P<.000). A positive SPT result to kiwifruit seeds was associated with severe symptoms induced by kiwifruit (P=.019) as a marker of advanced disease, but not with clinically relevant sensitization. Challenge testing with kiwifruit seeds performed on 8 seed-sensitized patients yielded negative results. CONCLUSION: Sensitization to Act d 1 is associated with a positive result in conventional diagnostic techniques, whereas kiwifruit seed sensitization does not increase the sensitivity of the diagnostic techniques evaluated.

OBJECTIVES: Obesity is subject to strong family clustering. The relatives of participants in weight-loss interventions may also modify their lifestyle and lose weight. The aim of this study was to examine the presence and magnitude of a halo effect in untreated family members of participants enrolled in a randomized, multi-component, lifestyle intervention. METHODS: A total of 148 untreated adult family members of participants in an intensive weight-loss lifestyle intervention (the PREDIMED-Plus study) were included. Changes at 1 and 2 years in body weight, physical activity, and adherence to a traditional Mediterranean diet (MedDiet) were measured. Generalized linear mixed models were used to assess whether the change differed between family members of the intervention group compared to the control. RESULTS: Untreated family members from the intervention group displayed a greater weight loss than those from the control after 1 and 2 years: adjusted 2-year weight change difference between groups was -3.98 (SE 1.10) kg (p < 0.001). There was a halo effect with regard to adherence to the MedDiet at one year which was sustained at two years: 2-year adjusted difference in MedDiet score change +3.25 (SE 0.46) (p < 0.001). In contrast, no halo effect was observed with regard to physical activity, as the untreated family members did not substantially modify their physical activity levels in either group, and the adjusted difference at two years between the 2 groups was -272 (SE 624) METs.min/week (p = 0.665). CONCLUSIONS: In the first prospective study to assess the influence on untreated family members of a diet and physical activity weight-loss intervention, we found evidence of a halo effect in relatives on weight loss and improvement in adherence to a MedDiet, but not on physical activity. The expansion of MedDiet changes from individuals involved in a weight-loss intervention to their family members can be a facilitator for obesity prevention.

BACKGROUND: Scholar photoprotection campaigns are among the most effective strategies for preventing skin cancer. Analysis of the target population constitutes a valuable starting point for the implementation of primary prevention strategies. Our aim is to study photoprotection habits, attitudes and knowledge among a Spanish school community. METHODS: Descriptive cross-sectional study targeting schoolchildren, parents and teachers at 20 schools in the area of the Costa del Sol Health Agency in southern Spain. Two population-specific, validated questionnaires were used: the CHRESI (for children aged 0-10 years) and CHACES Questionnaire(for adults and adolescents aged > 11 years). We collected demographic data, skin colour, skin phototype, sunburn episodes, sun exposure and photoprotection practices, attitudes and knowledge. RESULTS: 1728 questionnaires were analyzed (22% parents, 14.5% teachers, 44.8% adolescents and 18.6% children). The average ages were 8 years (children), 16 years (adolescents), 39 years (teachers) and 42 years (parents). Globally, the predominant features were: male sex (52%), Spanish nationality (92%) and phototypes II-III (61%). Children, followed by adolescents, reported the highest exposure to the sun, both in frequency and in duration. Adolescents had the higher rate of sunburn (75%), followed by parents/teachers (54.1%) and children (44.1%). Children and their parents were the most likely to adopt photoprotection measures, while adolescents presented more risky attitudes. Knowledge regarding photoprotection was acceptable (6.9/10). CONCLUSIONS: This study highlights the need to improve photoprotection knowledge, habits and attitudes among our target population. Scholars, parents and teachers in our area should be addressed in campaigns to promote healthy sun exposure habits, thus reducing skin cancer-related morbidity and mortality in this region.

OBJECTIVES: The objective of this study is to understand how Cuba responds to extreme weather events, which can help identify and disseminate good public health practice. STUDY DESIGN: The study design of this study is an observational study using routinely collected mortality data. METHODS: National daily mortality counts after severe hurricanes arrived on the Cuba landmass since 1990 were compared with baseline values. Incidence rate ratios of mortality during the hurricane and for the four weeks afterwards were calculated for four eligible hurricanes: Georges (1998), Dennis (2005), Ike (2008) and Irma (2017). RESULTS: Mortality rates decreased over time (P < 0.001 for interaction), and no excess mortality counts were observed after Hurricane Irma in 2017. CONCLUSIONS: Mortality rates for severe hurricanes that have made landfall in Cuba have decreased over three decades, despite the most recent hurricane (Irma) being one of the strongest observed in recent decades. This suggests that the Cuban public health preparations and responses to recent severe hurricanes are probably contributing to this mitigation in national mortality rates during these periods.

BACKGROUND: The anaerobic infection management is usually based on empirical treatment because anaerobic culture techniques take a long time due to their fastidious nature. The aim of this study was to analyze the etiological profile of severe anaerobic infections and AST data from clinical anaerobic bacteria isolated in a tertiary hospital in Madrid (Spain). MATERIAL AND METHODS: A consecutive study was carried out over 19 months in Ramón y Cajal Universitary Hospital, Madrid. Clinical samples were processed in appropriate anaerobic media and incubated using Anoxomat system. Identification was performed by MALDI-TOF. AST were determined with gradient diffusion method using EUCAST (penicillin, co-amoxiclav, imipenem, clindamycine and metronidazole) or CLSI (cefoxitin) breakpoints. RESULTS: During the period of study, 503 anaerobic microorganisms isolated from 424 clinical samples were included. Twenty-six percent of the cultures were monomicrobial, while 70.0% also contained aerobic bacteria. The most common source of infection was abscesses (26%), while blood infections represented the 11%. Anaerobic gram-negative bacilli were predominant (41%), being Bacteroides fragilis (13%) the most prevalent overall; anaerobic gram-positive bacilli represented 35%, anaerobic gram-positive cocci 19% and anaerobic gram-negative cocci 5%. Metronidazole and imipenem were the most effective agents tested against anaerobic bacteria, while clindamycin presented higher resistance rates. CONCLUSION: Antimicrobial susceptibility surveillance of anaerobic bacteria should be performed to monitor changes in resistance patterns and to be able to optimize empiric antimicrobial treatment. Reliable species identification and quick reporting of results would guide clinicians to select the optimal antimicrobial therapy.

Coronavirus disease 2019 (COVID-19) pandemic has caused significant impact on the health care system. As a consequence, diagnosis and treatment of vector borne diseases including dengue has been equally affected. Nepal is no exception to this, where COVID-19 cases is exponentially increased and all resources are concentrated on its prevention, control and management. Dengue, one of the major vector-borne diseases in Nepal, is apparently overlooked despite approaching the peak season of the disease. The aim of this paper is to describe the double burden of COVID-19 and dengue in Nepal, particularly highlighting the co-circulation and possible coinfections. This has posed higher risk of increased severity, more severe cases and deaths in Nepal. Moreover, potential misdiagnosis of these viral diseases may lead to delayed or, inappropriate treatment and poor allocation of resources.

BACKGROUND: Besides clinical signs and imaging, in recent years, biomarkers have proven to be a viable diagnostic resource for acute appendicitis (AA). OBJECTIVE: The objective of this study was to develop a clinical score including clinical signs and a combination of biomarkers to identify children with abdominal pain at low risk of AA. DESIGN/METHODS: We prospectively included children 2 to 14â¯years of age with abdominal pain suggestive of AA who presented to the emergency department between July 2016 and September 2017. A new score, the Pediatric Appendicitis Laboratory Score (PALabS) including clinical signs, leucocyte (WBC) and neutrophil (ANC) counts and plasma C-reactive protein (CRP) and calprotectin (CP) levels was developed and validated through secondary analyses of two distinct cohorts The validation sample included visits to a single pediatric emergency department from 2012 to 2013 and 2016 to 2017. RESULTS: The derivation sample included 278 children, 35.9% of whom had AA and the validation sample included 255 children, 49% of whom had AA. Using logistic regression, we created a 6-part score that consisted of nausea (3 points), history of focal right lower quadrant pain (4 points), ANC of ≥7500/µL (7 points), WBC of ≥10,000/µL (4 points), CRPâ¯≥â¯10.0â¯mg/L (2 points) and CPâ¯≥â¯0.50â¯≥â¯ng/mL (3 points). This score exhibited a high discriminatory power (area under the curve: 0.88; 95% confidence interval: 0.84 to 0.92) and outperformed the PAS and Kharbanda scores (area under the curve: 0.76; 95% confidence interval: 0.71 to 0.82 and 0.82; 95% confidence interval: 0.77 to 0.87, respectively). A PALabS ≤6 had a sensitivity of 99.2% (95% confidence interval [CI]: 95.6-99.9), negative predictive value of 97.6% (95% CI: 87.7-99.6), and negative likelihood ratio of 0.03 (95% CI: 0.00-0.18) in the validation set. CONCLUSION: In our validation cohort of patients with acute abdominal pain, the new score can accurately predict which children are at low risk of appendicitis and could be safely managed with close observation.

BACKGROUND: China and Spain are world leaders in the consumption of edible bulbs (garlic and onion), but there are few references to their capacity to cause allergic symptoms. The target was to study allergic sensitization and clinical symptoms associated with garlic and onion consumption in a large sample of allergic patients. METHODS: An observational cross-sectional study was conducted, testing garlic and onion extracts in 8109 patients of all ages seen by our allergy clinic in 2018. Forty-four aeroallergens and foods were tested, including garlic and onion, with prick test and determination of specific IgE. Oral provocation and contact tests were performed if a delayed reaction was suspected. Western Blot was performed in the serum of patients positive to garlic and onion. RESULTS: We conducted 356,798 skin tests and 4254 specific IgE determinations. Of the 8109 patients tested, 2508 (30.92%) presented with symptoms associated with food intake and, in these patients, food hypersensitivity was detected by skin test, positive specific IgE or provocation in 924 patients, and was caused by garlic or onions in 27, indicating a prevalence of 2.92%. Immunodetection showed an association between the symptoms and a specific LTP to these bulbs, without cross-reactivity with other LTPs in the Mediterranean diet (peach, wheat). CONCLUSIONS: Allergic hypersensitivity to garlic and onions should not be underestimated and, given their high consumption, should be included in the diagnostic food allergy battery.

Epidemiological studies report strong association between mood disorders and tobacco addiction. This high comorbidity requires adequate treatment but the underlying mechanisms are unknown. We demonstrate that nicotine exposure, independent of drug withdrawal effects, increases stress sensitivity, a major risk factor in mood disorders. Nicotine and stress concur to induce long-lasting cellular adaptations within the dopamine (DA) system. This interplay is underpinned by marked remodeling of nicotinic systems, causing increased ventral tegmental area (VTA) DA neurons' activity and stress-related behaviors, such as social aversion. Blocking ß2 or α7 nicotinic acetylcholine receptors (nAChRs) prevents, respectively, the development and the expression of social stress-induced neuroadaptations; conversely, facilitating α7 nAChRs activation specifically in the VTA promotes stress-induced cellular and behavioral maladaptations. Our work unravels a complex nicotine-stress bidirectional interplay and identifies α7 nAChRs as a promising therapeutic target for stress-related psychiatric disorders.

The TotaltrackTM is a new video laryngeal mask, which combines a supraglottic airway with a videolaryngoscope. We evaluated the performance of this device in an observational study in 300 adult patients. The Totaltrack was inserted at the first attempt and the glottis seen in all cases. In 249 patients (83%; 95%CI 78.7-87.3%) the glottis was seen at the first attempt. Adequate ventilation and tracheal intubation were achieved in all patients. The median time to visualisation of vocal cords, to confirmation of ventilation and to successful tracheal intubation was 5 s, 13 s and 24 s, respectively. Nineteen patients (6.3%; 95%CI 3.55-9.05%) suffered minor complications, such as mucosal lesion or blood staining. The Totaltrack appears effective for airway management.

INTRODUCTION AND OBJECTIVES: Biological aerosols play a vital role in the interactions between the atmosphere, biosphere, climate and public health and fungal spores are a component with allergic importance. We constructed a database in Castile & Leon (Spain) and carry out molecular-level component-resolved diagnosis to complete the air quality study carried out since 2006 by our aerobiological network (RACYL) to aid clinical diagnosis and treatment. METHODS: We reviewed a database of 19,774 patients (adults and children) with allergic respiratory disease treated in our unit during the last 12 years. We also made a component-resolved diagnosis of the molecules involved in the pathology in a randomly selected population of 150 patients. RESULTS: The dimeric glycoprotein Alt a1 from Alternaria is the most prevalent and most useful allergen in the diagnosis of patients with allergy to fungi in our area (94.4%), followed by enolase Alt a 6 (Alternaria), ribonuclease Asp f 1 of Aspergillus and mannitol dehydrogenase from Cla h 8 (Cladosporium). CONCLUSIONS: Our results have helped determine which spore molecules are most-closely associated with allergies. Molecular analysis will be useful to determine more accurate and useful immunotherapy in these patients.

OBJECTIVES: Cuba is a tobacco-producing country that has been economically isolated as a consequence of an embargo imposed by the USA. It has also experienced a severe economic depression in the 1990s after the withdrawal of support by the former Soviet Union. These characteristics provide a unique opportunity to study the relation between large changes in economic activity, cigarette price and demand for cigarettes in a relatively isolated socialist economy. STUDY DESIGN: This is an observational epidemiological study. METHODS: Data were obtained on the annual price of a packet of cigarettes and the mean number of cigarettes consumed per adult living in Cuba from 1980 to 2014. Descriptive and regression analysis were used to explore the relationship between cigarette consumption and price in Cuba. RESULTS: In 1980, the mean price of a packet of cigarettes was 1.53 Cuban peso (CUP) in 1997 prices and the mean annual per capita consumption was 2237 cigarettes. In 2014, the mean price had increased to 5.57 CUP (1997 prices) per packet of cigarettes, and consumption had fallen to 1527 cigarettes per capita. There were significant negative associations between annual cigarette consumption and both price and living through an economic depression. The elasticity was approximately -0.31 with price, and living through an economic depression was also associated with lower consumption of cigarettes (a reduction of 9%, 95% confidence intervals -0.18 to -0.001). CONCLUSIONS: Higher cigarette pricing, along with other public health interventions, are required to protect the national population from the adverse effects of tobacco smoke exposure.

Candida albicans is a commensal fungus of the skin and mucous membranes in humans, but it is also responsible for mucocutaneous and systemic infections in immunocompromised patients like low birth weight neonates and premature newborns. The epicutaneous application of C. albicans is widely used to study the immune response against this pathogen in adult mice models. However, the immune response of newborns against infections caused by the genus Candida is poorly understood. In order to mimic premature human infection, we developed a model of C. albicans epicutaneous infection in newborn mice. We found that yeasts were able to colonize while the pseudohyphae invaded the epidermis. Recruitment of polymorphonuclear and mononuclear cells at the infection zone was observed. Fungal invasion, fungal burden and cellular infiltration displayed a time- and dose-dependent response. Interestingly, newborn mice were able to control C. albicans primary infection. Finally, we showed that the epicutaneous infection of C. albicans in newborn mice at birth results in the induction of cell-mediated immunity as evinced by delayed-type hypersensitivity assays.

The unavailability of sufficient numbers of human primary cells is a major roadblock for in vitro repair of bone and/or cartilage, and for performing disease modelling experiments. Immortalized mesenchymal stromal cells (iMSCs) may be employed as a research tool for avoiding these problems. The purpose of this review was to revise the available literature on the characteristics of the iMSC lines, paying special attention to the maintenance of the phenotype of the primary cells from which they were derived, and whether they are effectively useful for in vitro disease modeling and cell therapy purposes. This review was performed by searching on Web of Science, Scopus, and PubMed databases from 1 January 2015 to 30 September 2019. The keywords used were ALL = (mesenchymal AND ("cell line" OR immortal*) AND (cartilage OR chondrogenesis OR bone OR osteogenesis) AND human). Only original research studies in which a human iMSC line was employed for osteogenesis or chondrogenesis experiments were included. After describing the success of the immortalization protocol, we focused on the iMSCs maintenance of the parental phenotype and multipotency. According to the literature revised, it seems that the maintenance of these characteristics is not guaranteed by immortalization, and that careful selection and validation of clones with particular characteristics is necessary for taking advantage of the full potential of iMSC to be employed in bone and cartilage-related research.

INTRODUCTION: A surgical intervention is a stress situation for every human being. Parents of children who undergo scheduled surgeries have some degree of anxiety about them. OBJECTIVE: To identify the main paternal concerns regarding surgery. Assess the influence of working in health (nurses, auxiliary staff and doctors) to underestimate, magnify or mislead the real concerns. MATERIAL AND METHOD: A comparative cross-sectional study was conducted between two populations divided by their relationship with the hospital setting that completed a questionnaire with 35 items. 138 questionnaires were collected and analyzed. RESULTS: Differences are observed regarding the perception we have, as hospital staff, of the levels, relationships and types of concerns that we believe parents present before their child's surgery regarding the true perceptions that these parents present. CONCLUSION: The present study shows that, although the hospital staff has experience in the management of pediatric patients and their family environment, the habituation to the hospital environment can generate small distortions in terms of the levels and groupings of the different concerns present before the hospital surgery of a child, having to take it into account to offer the best care work.
INTRODUCCION: Una intervención quirúrgica es una situación de estrés para todo ser humano. Los padres de niños que se someten a cirugías programadas presentan cierto grado de ansiedad con respecto a las mismas. OBJETIVO: El objetivo del presente estudio es identificar las principales preocupaciones paternas frente a la cirugía y valorar si la pertenencia laboral al mundo sanitario (enfermeros, personal auxiliar y médicos, principalmente) supone infravalorar, magnificar o equivocar dichas preocupaciones reales. MATERIAL Y METODOS: Se realizó un estudio transversal comparativo entre dos poblaciones divididas por su relación o no con el ámbito hospitalario que cumplimentaron un cuestionario con 37 ítems. Se recogieron y analizaron 138 cuestionarios. RESULTADOS: Se observan diferencias en cuanto a la percepción que tenemos, nosotros, como personal hospitalario, de los niveles, de las relaciones y los tipos de preocupaciones que creemos presentan los padres ante la cirugía de su hijo respecto a las verdaderas percepciones que presentan estos padres sin las vivencias diarias de una persona que trabaja en el mundo hospitalario. en dos ML al suspender el tratamiento. Tres pacientes presentaron hipertransaminasemia e hipercolesterolemia, sin precisar tratamiento médico. CONCLUSIONES: El presente estudio pone de manifiesto que, aunque el personal hospitalario tenga la experiencia sobre el manejo de pacientes pediátricos y su entorno familiar y, a pesar incluso, de poder tener hijos propios a su cargo, parece que la habituación a dicho ambiente hospitalario puede generar pequeñas distorsiones en cuanto a los niveles reales y a las agrupaciones de las distintas preocupaciones presentes ante la cirugía de un hijo. Esto debería tenerse en cuenta para ofrecer la mejor labor asistencial y mejorar el nivel de ansiedad que genera una intervención quirúrgica en el entorno familiar del paciente pediátrico.
