Population's Potential Accessibility to Specialized Palliative Care Services: A Comparative Study in Three European Countries.

BACKGROUND: Palliative care is a priority for health systems worldwide, yet equity in access remains unknown. To shed light on this issue, this study compares populations' driving time to specialized palliative care services in three countries: Ireland, Spain, and Switzerland. METHODS: Network analysis of the population's driving time to services according to geolocated palliative care services using Geographical Information System (GIS). Percentage of the population living within a 30-min driving time, between 30 and 60 minutes, and over 60 min were calculated. RESULTS: The percentage of the population living less than thirty minutes away from the nearest palliative care provider varies among Ireland (84%), Spain (79%), and Switzerland (95%). Percentages of the population over an hour away from services were 1.87% in Spain, 0.58% in Ireland, and 0.51% in Switzerland. CONCLUSION: Inequities in access to specialized palliative care are noticeable amongst countries, with implications also at the sub-national level.

Middle Cranial Fossa Approach: The Incudomalleolar Joint as a Reliable Landmark

Abstract Introduction The middle cranial fossa approach is performed by fewer neurotologists owing to a reduced number of indications. Consistent landmarks are mandatory to guide the surgeon in a narrow field. Objectives We have evaluated the incus and malleus head and the incudomalleal joint (IMJ) as a key landmark for identifying the superior semicircular canal (SSC) and to get oriented along the floor of the middle cranial fossa. Methods A combination of 20 temporal bone dissections and CT imaging were utilized to test and describe these landmarks. Results The blue line of the SSC is consistently identified along the prolongation of a virtual line through the IMJ and the angulation toward the root of zygoma. The mean distance from the zygoma toward the IMJ ranged from 1.60 to 1.90cm. Once the IMJ was identified, the blue line of the SSC was consistently found along the virtual line through the IMJ within 5 to 9mm. Conclusions The IMJ is a safe and consistent anatomical marker in the surgical approach to the middle cranial fossa floor. Opening the tegmen 1.5 to 2cm medial to the root of the zygoma and identifying the joint allows to trace a virtual line toward the SSC within 5 to 9mm. Knowledge of the close relationship between the direction of the IMJ and the superior canal can be used in all transtemporal approaches, thus orienting the surgeon in a rather narrow field with limited retraction of the dura and brain.

Combined Phacoemulsification and 360-Degree Endocyclophotocoagulation with and without a Kahook Dual Blade in Patients with Primary Open-Angle Glaucoma.

PURPOSE: The present study aimed to compare the outcomes of combined phacoemulsification and 360-degree endocyclophotocoagulation with and without goniotomy using a Kahook Dual Blade in patients with glaucoma. PATIENTS AND METHODS: We enrolled 37 patients, 21 of whom underwent combined phacoemulsification with 360-degree endocyclophotocoagulation and goniotomy using a Kahook Dual Blade (tri-modal therapy (T-MT) group). The remaining 16 patients underwent phacoemulsification with endocyclophotocoagulation (bi-modal therapy (B-MT) group). Visual acuity, intraocular pressure, and number of glaucoma medications were recorded before the study and postoperatively on the first day, at week 1, and at 1, 3, 6, 9, and 12 months. Surgical success was defined as an IOP ≤12 mmHg and ≥6 mmHg or an at least 20% reduction in IOP from baseline with (qualified success) or without medications (complete success). RESULTS: Forty-nine eyes were included. Baseline mean IOP was 16.96±3.66 mmHg and 15.64±4.88 mmHg in the T-MT and B-MT groups (p=0.122), respectively. At the 12-month follow-up, mean IOP values were 11.44±2.15 mmHg and 12.45±1.90 mmHg (p=0.031) in the T-MT and B-MT groups, respectively. Complete success rates were 37% in the T-MT group and 31% in the B-MT group, while qualified success rates were 74% and 50%, respectively. Glaucoma medications decreased from 2.0±1.4 to 0.8±1.0 (p<0.001) in the T-MT group and from 1.5±1.3 to 1.0±1.5 in the B-MT group (p=0.032). Similar improvements in visual acuity were observed in both groups. Complications were mild and resolved without intervention. CONCLUSION: The tri-modal treatment is safe and may be more effective in reducing IOP and glaucoma medication requirements than bi-modal treatment.

Primary outcomes of combined cataract extraction technique with Ab-Interno trabeculectomy and endoscopic Cyclophotocoagulation in patients with primary open angle Glaucoma.

BACKGROUND: Glaucoma surgery have been developed to lower intraocular pressure in a less invasive manner than traditional glaucoma surgery. The purpose of this article is to determine the outcome of using combined phacoemulsification technique, ab-interno trabeculectomy dual blade and endoscopic cyclophotocoagulation (ECP) surgeries in patients with primary open angle glaucoma. METHODS: A retrospective case series was performed on 27 consecutive eyes with both primary open-angle glaucoma (POAG) and cataract; each eye was treated with combined phacoemulsification, ab-interno trabeculectomy-Kahook Dual Blade and Endocyclophotocoagulation at Instituto de ojos Oftalmosalud, Lima, Peru, between April 2017 and May 2017. INCLUSION CRITERIA: 1) Patients with uncontrolled mild to advanced POAG (according to Glaucoma Grading Scale HODAPP) 2) cataract condition 3) treatment with two or more glaucoma medications due to rapid progression in the visual fields (at least two in a short period of time). Intraocular pressure (IOP), best corrected visual acuity (BCVA) logMAR and number of glaucoma medications were recorded prior to the study, at day 1, week 1, and 1,3,6 and 9 months after surgery. Primary outcome measure was surgical success defined in terms of IOP < 14 mmHg either with no medications (complete success) or with medications (qualified success). RESULTS: A total of 27 eyes from 27 patients were included. The mean basal IOP was 17.0 ± 3.7 mmHg and postoperatively was 11.6 ± 1.9 mmHg and 11.4 ± 1.8 mmHg (P < 0.001) at 6 and 9 months respectively. Glaucoma medications decreased from 1.9 ± 1.4 to 0.56 ± 1.05 at 9 month follow-ups (P < 0.001). Preoperative best corrected visual acuity (BCVA) showed and improvement from 0.4 ± 0.4 LogMAR to 0.2 ± 0.4 logMAR at 9 months. The main complication was blood reflux intra-operatively (66.7%), which resolved without re-operation. The mean IOP was reduced by 32.9% from baseline and the surgical success was 92,6%, (complete success 70,3% and qualified success 29,6%) at 9 months. CONCLUSIONS: In patients with POAG, combined treatment with phacoemulsification, ab-interno trabeculectomy and endoscopic cyclophotocoagulation effectively reduced IOP and glaucoma medication dependence.

Subclinical hypothyroidism and the risk of cancer incidence and cancer mortality: a systematic review.

BACKGROUND: Thyroid hormone has been shown to be involved in carcinogenesis via its effects on cell proliferation pathways. The objective of this study is to determine the association between subclinical hypothyroidism (SCH) and the risk of incident cancer and cancer mortality via systematic review. METHODS: A systematic search was performed on Medline and Pubmed to identify relevant studies. Randomized controlled trials, and observational studies assessing SCH or its treatment and the risk of incident cancer or cancer mortality were identified. RESULTS: A total of 7 cohort and 2 case-control studies met our inclusion criteria. In general, these studies were of medium to good quality. Overall, studies revealed no association between SCH and breast and prostate cancer. One study found that untreated SCH may be associated with an increased risk of colorectal cancer (adjusted odds ratio [OR]: 1.16; 95% confidence interval [CI]: 1.08-1.24). One study showed an increased risk in thyroid cancer incidence (adjusted OR: 3.38; 95% CI: 2.05-5.59) associated with elevation of a thyroid stimulating hormone (TSH) of > 1.64mIU/L. Two studies found an increase in cancer mortality among patients with SCH compared to euthyroid individuals; in contrast one study found no association between subclinical hypothyroidism and cancer mortality among aging men. CONCLUSION: The number of studies examining thyroid dysfunction and cancer risk and mortality is limited. Future studies assessing the association between thyroid dysfunction and cancer risk and mortality are needed, which will further address the need to treat subclinical hypothyroidism.

Imaging the Human Immunological Synapse.

The purpose of the method is to generate an immunological synapse (IS), an example of cell-to-cell conjugation formed by an antigen-presenting cell (APC) and an effector helper T lymphocyte (Th) cell, and to record the images corresponding to the first stages of the IS formation and the subsequent trafficking events (occurring both in the APC and in the Th cell). These events will eventually lead to polarized secretion at the IS. In this protocol, Jurkat cells challenged with Staphylococcus enterotoxin E (SEE)-pulsed Raji cells as a cell synapse model was used, because of the closeness of this experimental system to the biological reality (Th cell-APC synaptic conjugates). The approach presented here involves cell-to-cell conjugation, time-lapse acquisition, wide-field fluorescence microscopy (WFFM) followed by image processing (post-acquisition deconvolution). This improves the signal-to-noise ratio (SNR) of the images, enhances the temporal resolution, allows the synchronized acquisition of several fluorochromes in emerging synaptic conjugates and decreases fluorescence bleaching. In addition, the protocol is well matched with the end point cell fixation protocols (paraformaldehyde, acetone or methanol), which would allow further immunofluorescence staining and analyses. This protocol is also compatible with laser scanning confocal microscopy (LSCM) and other state-of-the-art microscopy techniques. As a main caveat, only those T cell-APC boundaries (called IS interfaces) that were at the right 90° angle to the focus plane along the Z-axis could be properly imaged and analyzed. Other experimental models exist that simplify imaging in the Z dimension and the following image analyses, but these approaches do not emulate the complex, irregular surface of an APC, and may promote non-physiological interactions in the IS. Thus, the experimental approach used here is suitable to reproduce and to confront some biological complexities occurring at the IS.

Do clinical and laboratory variables have any impact on the diagnostic performance of 18F-FDG PET/CT in patients with fever of unknown origin?

OBJECTIVE: To assess the influence of clinical features and laboratory test results on the determination of fever of unknown origin (FUO) by means of 18F-FDG PET/CT. METHODS: Retrospective and longitudinal analysis, including all the PET/CT studies requested for FUO. Reference standard was established by serology, cultures or biopsy with other laboratory tests or clinical follow-up when necessary. Clinical variables, inflammation markers, protein analysis, serology and culture results close to the PET scan were obtained. The final diagnosis was classified into three groups attending to the etiology; group 1: infection or neoplasm, group 2: vasculitis, autoimmune disease or non-infectious inflammatory disease and group 3: auto-limited fever or persistent fever without diagnosis. PET/CT scans were classified as positive or negative and helpful or not in the diagnosis of the fever origin. The effect of clinical features and laboratory variables on the PET/CT results was analyzed. RESULTS: Sixty-seven patients were evaluated. The final diagnosis was: Group 1 (25), Group 2 (20) and Group 3 (22). 89.6% of patients had a positive inflammation marker, 28.4% proteinogram alterations and 20.9% positive cultures. PET/CT was positive in 52/67 patients. PET/CT helped in the establishment of the fever origin in 35 cases and was especially helpful in groups 1 and 2. Sensitivity, specificity and accuracy of PET/CT were: 84, 31 and 61%. PET results shown significant relations with the final diagnosis (p = 0.035) and culture results (p = 0.037). No significant relations were observed with the rest of clinical or laboratory variables. CONCLUSIONS: 18F-FDG PET/CT had a high sensitivity but a low specificity in the diagnosis of the fever origin, probably due to the high rate of diffuse and auto-limited aetiologies. Patients who are most likely to benefit from the PET/CT study would be those with several positive inflammation markers, reflecting a higher pre-test probability of active disease.

Goal-directed Fluid Therapy Does Not Reduce Primary Postoperative Ileus after Elective Laparoscopic Colorectal Surgery: A Randomized Controlled Trial.

BACKGROUND: Inadequate perioperative fluid therapy impairs gastrointestinal function. Studies primarily evaluating the impact of goal-directed fluid therapy on primary postoperative ileus are missing. The objective of this study was to determine whether goal-directed fluid therapy reduces the incidence of primary postoperative ileus after laparoscopic colorectal surgery within an Enhanced Recovery After Surgery program. METHODS: Randomized patient and assessor-blind controlled trial conducted in adult patients undergoing laparoscopic colorectal surgery within an Enhanced Recovery After Surgery program. Patients were assigned randomly to receive intraoperative goal-directed fluid therapy (goal-directed fluid therapy group) or fluid therapy based on traditional principles (control group). Primary postoperative ileus was the primary outcome. RESULTS: One hundred twenty-eight patients were included and analyzed (goal-directed fluid therapy group: n = 64; control group: n = 64). The incidence of primary postoperative ileus was 22% in the goal-directed fluid therapy and 22% in the control group (relative risk, 1; 95% CI, 0.5 to 1.9; P = 1.00). Intraoperatively, patients in the goal-directed fluid therapy group received less intravenous fluids (mainly less crystalloids) but a greater volume of colloids. The increase of stroke volume and cardiac output was more pronounced and sustained in the goal-directed fluid therapy group. Length of hospital stay, 30-day postoperative morbidity, and mortality were not different. CONCLUSIONS: Intraoperative goal-directed fluid therapy compared with fluid therapy based on traditional principles does not reduce primary postoperative ileus in patients undergoing laparoscopic colorectal surgery in the context of an Enhanced Recovery After Surgery program. Its previously demonstrated benefits might have been offset by advancements in perioperative care.

The Influence of Proton-Pump Inhibitors on Glycemic Control: A Systematic Review of the Literature and a Meta-Analysis.

OBJECTIVES: Proton-pump inhibitors (PPIs) have shown antihyperglycemic effects by stimulating insulin secretion. The aim of this study was to analyze the effect of PPIs on glucose metabolism in general and any potential antidiabetes effects in patients with type 2 diabetes. METHODS: A systematic search was conducted in MEDLINE, Embase, Cochrane and PubMed. Studies using PPIs as interventions and reporting glucose levels, glycated hemoglobin (A1C) levels and insulin levels were selected. Weighted-mean differences (WMDs) were calculated for all outcomes. A random-effects model was used for moderate and high heterogeneity and a fixed-effects model for low heterogeneity data. RESULTS: The research included 9 studies have involving 320 patients in total. Among patients with type 2 diabetes, those exposed to PPIs did not see significant reductions in A1C levels; WMD -0.36, 95% confidence interval (CI) -0.87, 0.15; p=0.17. Pantoprazole resulted in a statistically significant reduction in A1C levels in patients with type 2 diabetes when compared to control interventions; WMD -0.93, 95% CI -1.49, -0.37; p=0.001. There was no statistically significant difference in other outcomes (p≥0.05). CONCLUSIONS: This meta-analysis demonstrates that PPIs, in general, do not decrease A1C levels in patients with type 2 diabetes. However, pantoprazole produced significant reductions in A1C levels in patients with type 2 diabetes. Given the limitations and the presence of bias in the primary studies, larger and better-quality studies are warranted.

Living at Higher Altitude and Incidence of Overweight/Obesity: Prospective Analysis of the SUN Cohort.

BACKGROUND: Residence at high altitude has been associated with lower obesity rates probably due to hypoxia conditions. However, there is no evidence of this association in a free-living population. OBJECTIVES: We assessed the association between the altitude where each participant of a Spanish cohort (the SUN Project) was living and the incidence of overweight/obesity. METHODS: The SUN Project is a dynamic, prospective, multipurpose cohort of Spanish university graduates with a retention rate of 89%. We included in the analysis 9 365 participants free of overweight/obesity at baseline. At the baseline questionnaire, participants reported their postal code and the time they had been living in their city/village. We imputed the altitude of each postal code according to the data of the Spanish National Cartographic Institute and categorized participants in tertiles. We used Cox regression models to adjust for potential confounding variables. RESULTS: During a median follow-up of 10 years, we identified 2 156 incident cases of overweight/obesity. After adjusting for sex, age, time of residence at current city, baseline body mass index, physical activity, sedentarism and years of education (≤ 3 years, ≥ 4 years, Master/PhD), those participants in the third tertile (>456 m) exhibited a statistically significant 14% reduction in the risk of developing overweight/obesity in comparison to those in the first tertile (<124 m) (adjusted HR = 0.86; 95% CI: 0.77, 0.96). CONCLUSIONS: Living in cities of higher altitude was inversely associated with the risk of developing overweight/obesity in a cohort of Spanish university graduates.

Performance of Dengue Diagnostic Tests in a Single-Specimen Diagnostic Algorithm.

BACKGROUND: Anti-dengue virus (DENV) immunoglobulin M (IgM) seroconversion has been the reference standard for dengue diagnosis. However, paired specimens are rarely obtained, and the interval for this testing negates its usefulness in guiding clinical case management. The presence of DENV viremia and appearance of IgM during the febrile phase of dengue provides the framework for dengue laboratory diagnosis by using a single serum specimen. METHODS: Archived paired serum specimens (n = 1234) from patients with laboratory-confirmed dengue from 2005 through 2011 were used to determine the diagnostic performance of real-time reverse transcription polymerase chain reaction (RT-PCR), for detection of DENV serotypes 1-4, and enzyme-linked immunosorbent assays (ELISAs), for detection of DENV nonstructural protein 1 (NS1) antigen and anti-DENV IgM. RESULTS: During 1-3 days after illness onset, real-time RT-PCR and NS1 antigen testing detected 82%-69% and 90%-84% of cases, respectively, as viremia levels declined, while anti-DENV IgM ELISA detected 5%-41% of cases as antibody appeared. Over the 10-day period of the febrile phase of dengue, the cumulative effect of using these 3 types of tests in a diagnostic algorithm confirmed ≥90% of dengue cases. CONCLUSIONS: The use of molecular or NS1 antigen tests to detect DENV and one to detect anti-DENV IgM in a single serum specimen collected during the first 10 days of illness accurately identified ≥90% of dengue primary and secondary cases.

Amanitinas / Amanitines

La intoxicación por consumo de hongos es un fenómeno estacional que se produce con relativa frecuencia en áreas geográficas donde es habitual su consumo, en especial de especies silvestres. Dependiendo del tipo de hongo ingerido pueden aparecer distintos cuadros clínicos (gastrointestinal, nefrotóxico, alucinatorio, etc.). El cuadro más grave es el hepatotóxico, asociado a una alta mortalidad, y causado por hongos que contienen amatoxinas (síndrome ciclopeptídico). Presentamos una revisión actualizada de las características de las amatoxinas, su cinética y mecanismo de acción, los métodos utilizados para su determinación analítica, así como las diferentes opciones para el tratamiento de la intoxicación (AU)

Mushroom poisoning is a seasonal phenomenon that occurs relatively frequently in geographical areas where its consumption is common. Depending on the type of fungus ingested different clinical symptoms (gastrointestinal, nephrotoxic, hallucinatory, etc.) can occur. Hepatotoxic syndrome caused by fungi containing amatoxins is the most serious condition, associated to high mortality. We present an updated review of amatoxins characteristics, kinetics, mechanism of action, methods used for analytical determination, as well as the different options for the treatment of poisoning (AU)

Desoxipipradrol. Fármacos antiguos, problemas nuevos / Desoxypipradrol. Old drugs, new problems

A través de Internet recientemente se han comercializado algunas sustancias estimulantes estructuralmente parecidas a neurotransmisores derivadas de medicamentos ya retirados, que potencialmente pueden causar cuadros clínicos de diversa gravedad. Su efecto estimulante y el hecho de que aparecen antes de prohibirse su consumo explican la denominación genérica de legal highs. La exposición a estas sustancias se manifiesta como cuadros parecidos a los del consumo de productos como fenciclidina, anfetaminas o cocaína, ya que muy probablemente compartan mecanismos de acción sobre la recaptación de dopamina en los núcleos cerebrales implicados en el comportamiento de gratificación. La escasez de información médica contrastada, y las dificultades para disponer de material de calibración constituyen un reto diagnóstico. El desoxipipradol, sintetizado hace más de 6 décadas para el tratamiento del trastorno hipercinético, fue relegado por el metilfenidato, un compuesto análogo. En 2009 reapareció como droga recreativa responsable de algunos cuadros clínicos de intoxicación (AU)

Stimulant substances previously used for therapeutic purposes, and are currently banned, have recently been marketed through the Internet. These drugs, structurally similar to neurotransmitters, can potentially cause severe clinical conditions. Exposure to these 'legal highs' results in symptoms similar to those of well-known substances such as phencyclidine, amphetamines or cocaine, probably because they share mechanisms of action related to dopamine reuptake in brain nuclei involved in the regulation of reward behavior. The limitations of medical evidence, as well as difficulties in obtaining calibration material, constitute an analytical challenge. Desoxypipradol was synthesized more than six decades ago for the treatment of hyperkinetic disorder, but was surpassed by methylphenidate, a similar compound with a better pharmacokinetic performance. In 2009 desoxypipradol appeared as a recreational drug involved in several cases of clinical intoxication (AU)

Predegenerated great auricular nerve graft in facial nerve defects.

OBJECTIVE: To compare axonal regeneration in an animal model after the repair of facial nerve defects with pre-degenerated (PD) and non-PD (NPD) great auricular nerve grafts. MATERIALS AND METHODS: The buccal branch of the facial nerve was completely sectioned in 18 New Zealand rabbits, which were randomized to 3 treatment groups: PD great auricular nerve graft repair (PD group), NPD great auricular nerve graft repair (NPD group), and immediate end-to-end repair (control group). Axonal regeneration was examined using optical microscopy to assess the following variables: total number of myelinated axons and regenerating sprouts (MARS) that crossed the distal anastomosis, numbers of intra and extrafascicular MARS, and area of myelinated axons. RESULTS: The total number of myelinated axons (p = 0.008) and intrafascicular axons (p = 0.02) that crossed the distal anastomosis significantly differed between the NPD and control group. No significant differences were observed between the PD and control group or between the PD and NPD groups. CONCLUSION: Nerve repair with PD grafts could be an alternative treatment in the management of injuries resulting in facial nerve gaps.
