[SARS-CoV-2 antibodies after booster vaccination. Identification of subgroups with poor response]. / Anticuerpos contra el SARS-CoV-2 tras la dosis de vacuna de recuerdo. Identificación de subgrupos con respuesta insuficiente.

Objective: To determine which patients within the high-risk group are most likely to have insufficient post-vaccination immunity. Methods: Determination of IgG titers against SARS-CoV-2 after the booster dose. Vaccine response was categorized as negative (IgG titers < 34 BAU/ml), indeterminate (titers 34 - 259 BAU/ml) or positive (≥ 260 BAU/ml). Results: 765 patients were included (31.25% of those vaccinated). 54 (7.1%) on treatment with biologics, 90 (11.8%) with hematologic disease, 299 (39.1%) with oncologic pathology, 304 (39.7%) with solid organ transplant and 18 (2.4%) with immunosuppression for other reasons. 74 patients (9.7%) had negative serology and 45 (5.9%) had indeterminate titers. By diagnostic group, the patients with the highest proportion of negative or indeterminate serology were patients with biologic treatment (55.6%, mainly at expense of antiCD20), hematologic (35.4%) and transplant patients (17.8%, mainly lung and kidney). Oncology and other immunosuppressed patients had a favorable response to vaccination. Conclusion: Patients treated with antiCD20 drugs, hematologic patients and transplanted patients (mainly lung and kidney) have a higher risk of not achieving post-vaccination immunity. It is essential to identify them in order to individualize and optimize their management.

[Health-related quality of life in patients recovered from COVID-19]. / Calidad de vida relacionada con la salud en pacientes recuperados de COVID-19.

INTRODUCTION: The presence of symptoms after acute SARS-CoV-2 infection is frequent and has an impact on patients' quality of life. The aim of this study is to assess the health-related quality of life of COVID-19 survivors and to ascertain which factors are related to worse results. METHODS: An observational, cross-sectional study has been performed, using, a telephone survey that was administered to all patients with COVID-19 from the first pandemic wave in our healthcare area 10months after the acute infection. Patients with dementia and nursing home residents were excluded. Health-related quality of life was assessed using the EQ-5D instrument and its índices EQ-VAS and EQ-Health Index. RESULTS: 443 answers were collected. Mean age was 54±16 and 38.4% of patients were male. The most affected domain was anxiety/depression (23.9% of patients) and mobility (16.5%). Mean global EQ-VAS score was 75.8±18.7, and mean EQ-Health Index was 0.884±0.174. Both VAS and Health Index scores were lower in females, patients older than 65 years, patients with comorbidities, and those who needed hospital admission during the acute infection. VAS scores in our sample were lower than in the general Spanish population, but similar to the scores in our region prior to the pandemic. Female sex, hospital admission, and a lower educational status were independently associated to lower EQ-Health Index scoring. CONCLUSION: While health self-perception is affected after COVID-19, this might not be directly related to the infection. There exist profiles of patients more prone to a worse quality of life in which interventions may be considered.

Analysis of the activity of interconsultations conducted by the departments of internal medicine. REINA-SEMI study: Registry of Interconsultations and Shared Care of the Spanish Society of Internal Medicine. / Análisis de la actividad de interconsulta realizada por los servicios de medicina interna. Estudio REINA-SEMI: Registro de Interconsultas y Asistencia Compartida de la Sociedad Española de Medicina Interna.

OBJECTIVE: To analyse the activity of interconsultations conducted by internal medicine (IM) departments, their formal aspects and the profile of clinical care required and to quantify the workload they represent. MATERIAL AND METHOD: A multicentre, observational prospective study was conducted with consecutive hospitalised patients treated by IM departments using interconsultations between May 15 and June 15, 2016. We estimated the workload related to this activity (1time unit [TU]=10min). RESULTS: We recorded 1,141 interconsultations from 43 hospitals. The mean age of the patients involved was 69.4 years (SD: 16.2), and 51.2% were men. The mean Charlson index was 2.3 (SD: 2.2). The most common reasons for the consultations were general assessments (27.4%), fever (18.1%), dyspnoea (13.6%), metabolic disorder (9.6%), arterial hypertension (6.3%) and delirium (5.3%). The duration of the first visit was 4 TUs (SD: 5.9) and 7.3 (SD: 21.5) for the sum of all subsequent visits. The surgical patients were older (70.6 [SD, 15.9] vs. 64.4 [SD, 16.3] years; P=.0001) and required more follow-up time (5 [SD, 7.3] vs. 3.5 [SD, 4.2] days; P=.009). The following issues were more common in the interconsultation format performed by medical services: number of regular interconsultations (response >24h), specification of the reason for the interconsultation, minimal data regarding the medical history and agreement on the appropriateness of the time spent with the consultant. CONCLUSION: The patients treated through interconsultations by the IM departments represented a significant workload. The interconsultations from the medical departments were more in line with the request format.

Paralysis of the external popliteal sciatic nerve associated with daptomycin administration.

WHAT IS KNOWN AND OBJECTIVE: Peripheral neuropathy has been associated with the administration of certain drugs. Few reports have described the association of daptomycin with the development of peripheral neuropathy, none of them with peroneal nerve involvement. CASE SUMMARY: We report a case of a 62-year-old man who developed external popliteal sciatic nerve paralysis after 22 days of therapy with daptomycin. WHAT IS NEW AND CONCLUSION: We present an uncommon and not previously reported adverse event. We have also analysed a possible alteration in a metabolic pathway (ABCB1 gene polymorphisms) that, in some patients, could explain certain drug adverse events. WHAT IS NEW AND CONCLUSION: We present an uncommon and not previously reported adverse event. We have also analysed a possible alteration in a metabolic pathway (ABCB1 gene polymorphisms) that, in some patients, could explain certain drug adverse events.

Epidemiological and sociodemographic factors associated with complicated alcohol withdrawal syndrome. / Factores epidemiológicos y sociodemográficos asociados al síndrome de abstinencia alcohólica complicado.

OBJECTIVES: To analyse the influence of epidemiological and sociodemographic factors in complicated alcohol withdrawal syndrome (AWS). MATERIAL AND METHODS: A multicentre, observational prospective study was conducted on consecutively added patients with AWS hospitalised in internal medicine departments. We recorded sociodemographic, epidemiological, clinical and progression data. Complicated AWS was defined as that which progressed with seizures or delirium tremens. RESULTS: We studied 228 episodes of AWS in 219 patients. The mean age was 54.5 years (SD, 11.5), and 90.8% were men. AWS was the cause for hospitalisation in 39.9% of the patients. Some 27.1% of the cases presented seizures, and 32.4% presented delirium tremens. The daily quantity of alcohol ingested was 17.8 standard drink units (SD, 21.4), with 16.6 years of dependence (SD, 11.3). The pattern of alcohol abuse was regular in 82.8% of the patients. Some 38.4% of the patients were married or had a partner, and 45.6% had children. Some 72.7% of the patients were unemployed or retired. Some 68.5% had only completed primary studies. Some 4.8% consumed cannabis, 5.2% consumed cocaine and 3% consumed opioids. The independent variables related to complicated AWS were consumption of a drug other than alcohol (OR, 5.3; 95% CI 1.5-18.7), low education level (OR, 3.4; 95% CI 1.6-7.3) and hospitalisation for AWS (OR, 2.9; 95% CI 1.5-5.6). The model's receiver operating characteristic area was 0.718 (95% CI 0.643-0.793). CONCLUSIONS: Concomitant drug abuse and a low educational level could help identify patients at risk of complicated AWS.

Inpatient alcohol withdrawal syndrome. / Síndrome de abstinencia alcohólica en pacientes hospitalizados.

A 55-year-old man was admitted for a femur fracture; an alcohol fetor was noted on admission. The following day, the patient began to experience tremors and nervousness. Intravenous haloperidol was administered. Shortly afterwards, the patient experienced two generalized seizures and then began to experience delirium and uncontrollable agitation. The patient was diagnosed with alcohol withdrawal syndrome; high doses of intravenous midazolam were prescribed and infused. A few hours later, the patient presented signs of respiratory depression, requiring a transfer to the intensive care unit. After a review of the medical history, it was determined that the patient had been admitted on 3 previous occasions due to alcohol withdrawal and had progressed to delirium tremens after experiencing seizures. Can the risk of alcohol withdrawal syndrome and the need for prophylactic treatment be assessed on admission? Were appropriate monitoring and treatment measures employed? Would it have been possible to change his outcome?

Review of use of drugs for conditions not included in product characteristics.

Off-label use of medication is common in hospital clinical practice and should be applied together with follow-up of a healthcare treatment protocol and in compliance with a procedure which ensures that the patient is informed and that he or she provides informed consent. A review of the literature on controlling 310 disorders showed that off-label use was indicated for 69 of them (22.3%) with the minimum required scientific evidence. It would be useful for the Pharmacy and Therapeutics Committee to have a list of the disorders that can be controlled using off-label drugs, providing a reference to those disorders which must follow a healthcare treatment protocol. A list of the mentioned characteristics is also useful for the hospital pharmacist for validating prescriptions, as it would provide a reference for assessing prescriptions which at first sight could seem questionable. Finally, this list would be very useful if a search index of all the drugs by disorder were to be included in the Pharmacotherapeutic Guide. It would complement the usual indices which include active ingredients and specialties.

[Risk factors for the development of medical complications in patients with hip fracture]. / Factores de riesgo para la presentación de complicaciones médicas en enfermos con fractura de cadera.

OBJECTIVE: To evaluate the clinical features and outcome of inpatients with hip fracture and to investigate the clinical variables associated with the risk of medical complications. METHODS: Prospective study of hip fracture patients aged 65 or more, admitted to the Department of Orthopaedic Surgery of the Xeral-Calde Hospital, in Lugo, Spain, in 2008. The different clinical and biochemical variables as regards the baseline health status and presentation features of the hip fracture and its complications were all recorded. The factors associated with the development of medical inpatient complications, including death, were determined, using univariate and multivariate analyses. RESULTS: A total of 258 patients were studied. The mean age was 82.2 (9.5) years, and 76% were women. The fracture was osteoporotic in 96.8%, and 92.6% were treated surgically. The mean Barthel index was 72.9 (25.7) and the age adjusted Charlson comorbidity index was 5.2 (1.5). A total of 63.9% patients had a major medical complication during their hospital stay. Mortality was 5.8%. The following variables were associated with the development of medical inpatient complications: Barthel index (OR=2.21; 95% CI, 1.1-4.25; p=0,01), age (OR=1.09; 95% CI, 1.02-1.12; p=0.006), haemoglobin at admission (OR=0.76; 95% CI, 0.62-0.93; p=0.01). CONCLUSIONS: Patients with hip fracture are fragile elderly with a high degree of functional dependence and comorbidity. Those with a high risk of developing medical inpatient complications can be identified at admission.

[Clinical course and features of the alcohol withdrawal syndrome in a general hospital]. / Manifestaciones y curso clínico del síndrome de abstinencia alcohólica en un hospital general.

INTRODUCTION: Despite its frequency and high clinical burden, few studies have analyzed the clinical features of the alcohol withdrawal syndrome in a hospital setting. Our purpose was to describe its manifestations and clinical course in a general hospital. PATIENTS AND METHODS: Patients with a diagnosis of alcohol withdrawal since January 1983 to December 2003, according to the revised fourth edition of the Diagnostic and Statistical Manual of Mental Disorders criteria, at the Xeral-Calde General Hospital in Lugo, were studied. Clinical and biochemical data at admission were collected, as well as those referred to the clinical course and complications. RESULTS: 539 episodes in 436 patients were included. Mean age was 45 (standard deviation: 12), and 91,3% were men. Abstinence was the reason for admission in 62,3%. 71,1% had a diagnosis of delirium tremens during their stay. Hallucinations were present in 59,7%, and convulsions (most of them generalized) in 41%. Patients with delirium tremens had greater elevations in temperature, heart rate and blood pressure, as well as more convulsions than minor withdrawal cases. Cirrhosis was present in 10%. The admission rate to the Intensive Care Unit (ICU) was 37,8% (95% confidence interval [95%IC]: 33,1-37,8). Of these, 69,9% needed mechanical ventilation. Mortality rate was 6,6% (95%IC: 4,2-9,1). 62% of patients died after admission in the ICU. CONCLUSION: The majority of complications related to the alcohol withdrawal syndrome in a hospital setting develop in patients with delirium tremens. They are especially related to the rate of admissions to the ICU and the use of mechanical ventilation.

[Analysis of the investigation activity of the internist from the Public Bid of Employment in Galicia]. / Análisis de la actividad investigadora de los internistas gallegos a partir de los resultados de la oferta pública de empleo.

OBJECTIVES: The aim of the present study was to assess the investigative activity of the internists. Data were collected from the Public Bid of Employment (PBE) performed in Galicia in 2005, and compared with the rest of medical subspecialities. METHODS: The results from the PBE related to internal medicine and medical subspecialities are available in the web page of the Galician Service of Health. The following data were studied: speciality, sex, method of attainment of the specialist degree, thesis, and scores obtained in Galician language exam, professional experience, professional report, postgraduate teaching and published scientific papers. RESULTS: Data from 355 specialists were analyzed: 118 (33.2%) were internists, and 237 (66.8%) were medical subspecialists. There were no differences between internal medicine and the rest of subspecialities in terms of sex, method of attainment of the specialist degree, thesis, and scores obtained in Galician language exam, professional experience and postgraduate teaching. Internists presented fewer scientific papers than subspecialists, even when they were classified according to different levels of professional experience. Degrees obtained by the MIR system were associated with more publications (p < 0.001). The attainment of the job was associated to scores obtained in the professional report, professional experience, and published scientific papers (p < 0.001). The obtaining of the job was associated to the accomplishment of the doctoral thesis in the university teaching hospitals (A Coruña, Santiago y Vigo, p < 0.005). CONCLUSIONS: The investigative activity of the internists in Galicia is inferior to the rest of the medical subspecialists. It seems necessary to stimulate the internists to developing scientific investigation and to improve those skills of the internal medicine residents.

[Should we use oral replacement for vitamin B12 deficiency as the first option of treatment?]. / 'Debemos utilizar la vía oral como primera opción para el tratamiento del déficit de vitamina B12?

OBJECTIVE: Analyze whether the tablets available in Spain are useful for oral replacement in the treatment of vitamin B12 deficiency. METHODS: From June 2003 to December 2005, patients with vitamin B12 deficiency attended at the Internal Medicine Clinic, were offered the possibility of starting or switching to oral therapy. Clinical and biochemical responses were monitored at baseline and at 2, 4, 6, 12, 18 y 24 months of follow-up. RESULTS: Twenty-eight patients were included (55.6% women), with a mean age of 74.96 +/- 9.98 years. Twenty-three cases (82.1%) had pernicious anemia, and 5 were gastrectomized. Patients who switched from intramuscular to oral therapy (16 cases) showed no decrease in the mean values of hemoglobin and B12 levels during the follow-up. Patients who started on oral therapy showed an increase in the values of hemoglobin (from 9.9 +/- 2.8 g/dl to 13.5 +/- 1.1, p = 0.003) and vitamin B12 (from 118 +/- 50 pg/ml to 496 +/- 229, p = 0.001) as early as two months after baseline, maintaining the response during the follow-up. No patient refused oral therapy and no toxic effect attributed to oral therapy was recorded. CONCLUSIONS: Oral replacement of vitamin B12 deficiency with the tablets available in Spain is safe, effective and acceptable to patients.

[Health status of the oldest old: functional and medical situation in centenarians]. / Estado de salud de los muy ancianos: situación clínica y funcional de la población centenaria.

OBJECTIVE: We planned a prospective and descriptive analysis of the centenarian population in Lugo sanitary area, establishing their social, functional and medical status as well as its relationship with their basic hematological and biochemical parameters. MATERIAL AND METHODS: During the study period between January 2001 and September 2003, participants were visited at home by a doctor and a nurse. The following variables were assessed: social status, past medical history, physical examination, functional status (Barthel index), blood analysis. RESULTS: 54 centenarians were interviewed, 16 men and 38 women. 75.9% were widows; 87% lived with their family and 57,4% in urban areas. 79.6% had followed studies. All of them had their own incomes. Regarding past medical history, 64.8% had some visual or auditive disturbances, 81.5% were taking medical drugs, 59.3% had some surgical intervention and 46.3% had been hospitalized for medical reasons. Their vaccination status was poor. Functional status, assessed by Barthel index, showed an average of 59 +/- 36.4, higher in men (82.7 +/- 28.7) than in women (49.6 +/- 35.1) (p<0.003). Blood samples were analyzed in 51 cases, there were not significant differences among them regarding sex or physical disability. CONCLUSION: The features of the centenarian population of Lugo are similar to other countries. It is an heterogeneous group. There are more women, but their clinical and functional status are significantly worse than in males. We have not founded a relationship between hematological and nutritional parameters and the degree of functional dependence in centenarians.

[The internist's role in the medical evaluation of surgical patients]. / Papel del internista como consultor de servicios quirúrgicos.

OBJECTIVE: To describe the characteristics of the consultations carried out by surgical services to an Internal Medicine service and to determine what factors influence the prognosis of these patients. METHODS: A prospective study of the consultations carried out by the surgical services of a 540-bed hospital to an Internal Medicine service. Analyzed variables were: age, sex, service of reference, reason for consultation, medical and admission diagnoses done during the admission, and clinical evolution. RESULTS: In the study 453 interconsultations were included, corresponding to 0.96 new interconsultations by working day and to 4.05 interconsultations per every 100 admissions in surgical services during the period study. The reasons for the more common consultations were dyspnea, fever, electrolytic and metabolic disorders, assessment of multiple conditions and acute confusional syndrome. Two or more diagnoses were carried out in 257 patients (56.7%). The average number of visits carried out by patient was 3.9 +/- 3.9. The average hospital stay in the study group was 28 +/- 33.05 days, while the average hospital stay of patients admitted in the surgical services during the same period was 11.6 days. Fifty patients (11%) had died at the time of the "medical discharge", and this percentage amounted to 20.5% (93 cases) upon considering the end of the hospital admission, compared with the global mortality of 3.7% registered during that period in the surgical services. The number of medical diagnoses and the age were independent predictors of mortality in the multivariate analysis. CONCLUSIONS: The interconsultations of the surgical services to an Internal Medicine service imply an important workload. The patients are complex from the medical standpoint. The average hospital stay and mortality of these patients are different from that of the patients cared in surgical services.

[Advanced gastric cancer: characteristics at presentation and therapeutic possibilities].

OBJECTIVE: To analyse the presentation forms and prognosis of patients with advanced gastric cancer at the time of diagnosis. DESIGN: Retrospective cohort study. PATIENTS AND METHODS: We studied all patients with gastric cancer (n=2,334) and synchronic metastases diagnosed in Lugo and A Coruña hospitals between 1975 and 1993. We estimated survival probability using the Kaplan-Meier method, and prognostic factors with Cox's regression models. RESULTS: Metastases were detected at the time of diagnosis in 585 (25.1%) patients, with the liver (346; 14.8%) and peritoneum (61; 6.9%) being the most frequently involved sites. The liver was exclusively affected in 213 (9.1%) cases, the peritoneum in 70 (3.3%), and another intraabdominal site in 121 (5.2%). Patients with peritoneal metastases were older (p=0.05), more commonly had a diffuse type of cancer according to Lauren's tumor classification (p<0.001), and underwent surgery more frequently (p=0.01). Curative resection was possible for only 11 (5.2%), 7 (10%), and 25 (20.7%) patients with metastases in only the liver, peritoneum, or another site, respectively, but in all cases survival probability was significantly enhanced. No surgery (HR=2.92), and simultaneous involvement of the liver and peritoneum (HR=1.62) were factors associated with a higher mortality rate. CONCLUSIONS: Patients with gastric cancer and metastases in only one intraabdominal organ show characteristic forms of presentation. Furthermore, in all cases candidacy for surgery should be carefully evaluated, as prognosis may improve in selected patients.

[Centenarian patients attended at a general hospital]. / Pacientes centenarios atendidos en un hospital general.

BACKGROUND: To report the social and medical situation of centenarian patients who required emergency hospital care during the last 8 years. METHOD: Retrospective study of patients aged over 100 years attended at the Emergency Department of a general hospital. The percentages of admissions and mortality rates were then compared with those among patients aged over 65. RESULTS: A total of 51 consultations from 41 patients were recorded, with a mean age of 101.2 years. The number of consultations increased gradually with time (p = 0.008). Ninety-three percent of patients lived with their families, predominantly in the rural setting. The most prevalent conditions included the prostatic syndrome (among males), heart failure and chronic obstruction to the airflow. Only 20% of patients had dementia. Sixty-four percent of consultations required hospital admission, with a mortality rate of 20.5% in this group of patients. The most common discharge diagnoses were heart failure and acute cerebrovascular accident. CONCLUSIONS: A gradual increase in hospital care is likely to be excepted among centenarians, who have an acceptable health status, although with a high risk of mortality during hospital admission.
