It is necessary to identify which factors or comorbidities are associated with more severe hidradenitis suppurativa, aiming to identify which patients may benefit more from early systemic treatment or a more aggressive approach. A retrospective study was conducted, including patients diagnosed with HS at the dermatology department of a Spanish hospital over a 5-year period. A total of 322 patients were included. A relationship was found between diagnostic delay, the presence of acne conglobata, pilonidal sinus, cardiovascular risk factors (hypertension, dyslipidemia, and/or diabetes mellitus) and more severe HS. No significant relationship was found between psychiatric comorbidities and the severity of the HS. The presence of perianal or truncal involvement was significantly associated with severe HS. Female sex and the presence of a family history of HS were associated with an earlier onset of the disease.

Hidradenitis suppurativa (HS) is a chronic and debilitating inflammatory disease derived from the pilosebaceous unit, that affects approximately 1% of the general population. Clinically, it is characterized by inflammatory nodules, abscesses, and tunnels in the intertriginous areas of the body, especially in the axillary, inguinal, and anogenital regions. The etiopathogenesis of HS is not completely understood, although it is considered to be multifactorial, and the result of a complex interaction between genetic, hormonal, environmental, and immunological factors. In this sense, several proinflammatory cytokines, such as tumor necrosis factor-alpha (TNF-α), interleukin (IL)-L-1β, and IL-17, among others, appear to play a crucial role in the pathogenesis of the disease. Currently, HS is recognized as a systemic disease associated with numerous comorbidities, including cardiovascular, immune-mediated, and endocrine-metabolic diseases. The treatment of HS must be carried out with an individualized and patient-oriented approach, considering medical and surgical treatment modalities.

BACKGROUND: Excess weight is a public health problem associated with a greater burden of chronic diseases and increased use of health resources.
METHODS: A subsample of Spanish adults aged 18-45 from the 2017 Spanish National Health Survey (N=7081) was used. The odds ratios of service utilisation of the group with BMI≥30kg/m2 were compared to the normal-weight group, using a model adjusted for sex, age, education, socioeconomic level, perceived health status and the presence of comorbidities.
RESULTS: In all, 12.4% of the sample had obesity. Of these, 24.8% visited their general physician, 37.1% attended emergency services and 6.1% were hospitalised during the last 12 months, which were significantly higher rates than in the normal-weight population (20.3%, 29.2%, 3.8%, respectively). However, 16.1% visited a physiotherapist and 3.1% used alternative therapies, compared to 20.8% and 6.4% in the healthy weight group. After adjusting for confounding factors, people with obesity were more likely to visit emergency services (OR: 1.225 [1.037-1.446]) and less likely to visit a physiotherapist (OR: 0.720 [0.583-0.889]) or use alternative therapies (OR: 0.481 [0.316-0.732]).
CONCLUSIONS: Spanish young adults suffering from obesity are more likely to use some health resources than those of normal weight, even after adjusting for socioeconomic variables and comorbidities, but they are less likely to attend physical therapy. The literature shows that these differences are less marked than in older ages, so this stage of life could be a window of opportunity for prevention to achieve better resource management.

BACKGROUND: Psoriatic arthritis (PsA) is a chronic inflammatory disorder that primarily affects the joints and entheses. In addition, it is associated with depressive syndrome (DS), cardiovascular disease, hypertension (HT), diabetes mellitus (DM), obesity and psoriasis (Pso). There are few studies aimed to analyze the association of the involvement of the musculoskeletal system with sexual function (SF).
METHODS: A cross-sectional observational study was proposed in patients diagnosed with PsA, to whom self-administered validated questionnaires were applied to determine alterations in SF: MGH-SFQ and CSFQ-14, which assess the 4 domains of sexual function; Qualisex and DLQI designed for joint and dermatological pathology respectively, which explore sexual aspects. The objective was to describe the existence of altered sexual function in patients with PsA; analyze the association between sociodemographic characteristics, comorbidities (Pso, DS, cardiovascular risk factors) and the treatments of patients on SF; and describe differences of SF according to gender.
RESULTS: 72 patients were evaluated. It was observed that the variables of patients with PsA that were associated with lower scores in SF were gender and age in the CSFQ-14 and MGH-SFQ; annual incomes, treatment with NSAIDs, DL and depression were associated with worse results in some domains of the sexual sphere.
CONCLUSIONS: Patients with PsA had impaired SF, especially women, elder patiens, those with low annual incomes, DL and emotional disorders. Anti-inflammatory treatments were associated with better SF. Globally, the chronic disease and the psychological burden behaved as factors associated with sexual dysfunction.

Heart failure (HF) is among the leading causes of morbidity and mortality worldwide. Several conditions trigger left ventricular chronic pressure or volume overload, hypertrophy, systolic and diastolic dysfunction, leading to cardiac remodeling and a rapid progression toward HF. Therapeutic interventions elicit reverse remodeling (RR), a highly variable myocardial response that ranges from none to total ventricular structural/functional recovery. However, HF patients present several comorbidities and medications that mask a comprehensive molecular knowledge of RR and hinder the identification of potential biomarkers of its progression or prognosis. Therefore, instead of using this heterogeneous population or even animal models to understand myocardial remodeling, we propose studying pregnancy-induced cardiovascular remodeling and postpartum-induced RR.
To assess cardiovascular functional and structural adaptations during pregnancy and in postpartum, characterizing the associated molecular changes; as well as to explore the impact of hypertension, obesity and diabetes on these processes.
We will perform echocardiography and assess endothelial function and arterial stiffness (EndoPAT® and pulse wave velocity, respectively) and assess potential markers of remodeling and RR using plasma and urine samples from pregnant women. To translate to a HF context, we will determine the impact of risk factors (hypertension, obesity and diabetes) by studying subgroups of pregnant women with these comorbidities.
Not applicable.
We are convinced that understanding the impact of these comorbidities in such a homogeneous population, such as pregnant women, provides a valuable model to unveil the most relevant pathologic and often masked signaling pathways underlying cardiac remodeling and incomplete RR in a heterogeneous population, such as HF patients. Moreover, we expect to identify potential novel biomarkers of RR progression/prognosis more easily.

BACKGROUND: We describe a series of pediatric cases of bacteremia, all of them with a history of heart disease, use of central venous catheter and coinfections. A review of the published literature was carried out in order to enrich the available information.
METHODS: Pediatric observational retrospective study in which three cases of catheter-related bloodstream infection due to Chryseobacterium indologenes were reported in a period of two years in a tertiary care hospital. The analysis was performed with the cases previously reported in the literature.
RESULTS: Three cases were reported in our center in a period of two years. We found 26 cases reported in the literature. Overall mortality was 26.92% (7/26).
CONCLUSIONS: This microorganism with characteristics of multidrug resistance is associated with the use of medical devices in hospitalized patients. Early identification of this pathogen is crucial to starting treatment.

BACKGROUND: Different obesity-related comorbidities already present in childhood, such as: vitamin D deficiency, impaired carbohydrate metabolism, dyslipidaemia, arterial hypertension and non-alcoholic steatohepatitis. In this study, we aim to analyse the prevalence of comorbidities and to determine the predictive factors that affect these comorbidities.
METHODS: Anthropometric, demographic and biochemical variables were collected from obese patients between six and 18 years of age. Subsequently, a statistical analysis was performed to describe the characteristics of the patients and the prevalence of comorbidities, as well as their predictive factors.
RESULTS: A total of 158 obese children (76 boys and 82 girls) with a mean age at diagnosis of 12.48 years and a BMI Z-score of +3.24 SDS were included. The most prevalent comorbidities were vitamin D deficiency (64.2%), insulin resistance (45.1%), dyslipidaemia (32.2%), hyperuricaemia (18.5%) and arterial hypertension (15%). Age, BMI Z-score, percentage of fat mass and male sex have been found to be predictors of these comorbidities.
CONCLUSIONS: Obese children and adolescents have a high prevalence of comorbidities. Once the diagnosis of obesity has been established, it would be very useful to identify early those patients with a higher risk of comorbidities, knowing their relationship with sex, age, BMI Z-score, percentage of fat mass and pubertal stage.

OBJECTIVE: Chronic nodular prurigo (CNPG) is a recently defined and currently underdiagnosed disease with a variety of causes. It is associated with multiple comorbidities, and its management and treatment have improved with a better understanding of its pathogenesis. The aim of this study was to describe our experience with a series of patients with CNPG.
METHODS: Single-center, observational, retrospective study of the sociodemographic and clinical characteristics of patients with CNPG seen at the dermatology department of a tertiary care hospital between 2009 and 2021.
RESULTS: We included 74 patients, mostly women (63.5%), with a mean age of 57 years. Overall, 39.2% of patients had a concomitant skin condition, mainly atopic dermatitis (62%). Other comorbidities included endocrine disorders (54.1%), cardiovascular disease (44.4%), and psychiatric disorders (36.5%). Skin biopsy helped confirm the clinical diagnosis in 70% of cases. The mean immunoglobulin E level was higher than normal (516IU/mL), regardless of atopic predisposition. On average, patients received three treatments, the most common choices being methotrexate, antihistamines, and topical and oral corticosteroids. Methotrexate was among the most effective options.
CONCLUSIONS: CNPG is a complex disease associated with multiple comorbidities. It requires a multidisciplinary approach, with the dermatologist at the center. Classical treatment approaches are probably insufficient.

BACKGROUND: Necrotising fasciitis is a potentially life-threatening soft tissue infection that mainly affects the fascia and deep planes, with a very high mortality rate and severe related complications.
OBJECTIVE: To evaluate clinical and demographic characteristics of patients with necrotising fasciitis in our hospital and to describe their diagnostic and therapeutic management.
METHODS: Retrospective review of medical records of 21 patients diagnosed with necrotising fasciitis with limb involvement between January 2003 and February 2021 in our hospital. Demographic data, clinical features and details of management and prognosis were collected for each patient.
RESULTS: Of 21 patients included, 15 were male (71.43%), with a mean age at diagnosis of 54.38±19.55 years. The most frequent comorbidities were insulin-dependent diabetes mellitus in seven patients (33.33%) and a history of cancer in five patients (23.81%). Infection was monomicrobial in 14 cases (66.66%), with Streptococcus pyogenes being the most frequent microorganism; multiple pathogens were isolated in 2 patients (9.52%) and no microorganism was identified in 5 patients (23.81%). All patients underwent surgery at our hospital, with a mean of 4.14±3.98 surgeries. Only one patient underwent amputation of the affected limb. The mean hospital stay was 23.14±16.44 days, with an overall mortality of 47.62% (10 cases).
CONCLUSIONS: Despite being a rare disease, necrotising fasciitis is a very aggressive pathology, with a high mortality rate, especially in immunocompromised patients. Advanced age and oncological disease are potential factors of worse prognosis in the evolution of this condition.
