RESUMEN
In order to replenish iron stores and bring hemoglobin (Hb) levels back to normal, oral iron is the primary treatment option for women with iron deficiency anemia (IDA). This study investigated the efficacy and side effects of daily versus alternate-day, given single doses versus double doses oral iron supplementation for treating IDA. A retrospective cohort study was performed between 2021 and 2022, including 120 patients. Study group were divided into 4 age-sex-matched groups; Group I (nâ =â 30) and Group II (nâ =â 30) which were received ferrous sulphate tablets daily in single or double doses, respectively, containing 60 mg of elemental iron each. Groups III (nâ =â 30) and IV (nâ =â 30) were received a single and double dose on alternate days, respectively. The primary outcome was the mean difference in Hb from baseline at week 4. Gastrointestinal (GI) side effects were accepted as a secondary outcome. The daily single dose and alternate day double dose groups had median Hb changes of 2.3 (2.1) and 2.6 (1.8) g/dL. The differences in Hb between Groups I and II, I and III, and Groups IV and II, IV and III were significant (Pâ <â .001, Pâ =â .001, Pâ <â .001, and Pâ <â .001, respectively). There is no significant difference between groups regarding improving iron parameters such as serum iron, total iron binding capacity, transferrin saturation, and ferritin. The incidence of GI side effects were greater in double doses than in single doses of daily or alternate-day therapies (43.3% and 30% vs 10% and 3.3%). Daily or alternate-day double dose resulted in more side effects but less therapeutic efficacy in women with IDA. To find the best supplementation method, randomized controlled trials with a larger sample of participants, longer study lengths, and various iron doses may be helpful.

Oral mucositis (OM) is a common side effect in patients undergoing chemotherapy (CT), especially in children due to their rapid epithelial mitotic rate. It has been associated with a significant reduction in life quality since it leads to pain, an inadequate intake of nutrients, an increased risk of opportunistic infections, and interruptions of CT. Photobiomodulation (PMB) with low-level laser therapy (LLLT) has shown faster healing, reduction in pain, and the reduced use of analgesic compared to placebo groups. The purpose of this review is to analyze and compare the existing clinical trials and identify their shortcomings in hope to make future research easier. Using MeSH terms and keywords, the Embase, Medline, and PubMed databases we searched for the period of the last 5 years. We identified a total of 15 clinical trials, with a total of 929 pediatric patients analyzed in this review. We compared different light sources and other laser technique characteristics used in clinical trials such as wavelength, energy and power density, spot size, irradiation time, PBM protocol, and OM evaluation. The main findings show inconsistent laser parameter quotations, differences in the PBM protocol along with a laser application technique, and a lack of clinical trials. Based on that, more studies with a high methodological quality should be conducted in order to provide a unified PBM protocol suitable for the pediatric population.

BACKGROUND: Nausea and vomiting are among the most common adverse effects experienced by cancer patients undergoing treatment worldwide. Their treatment with pharmacologic therapy can often be complicated by medication interactions and other unwanted side effects. The aim of this systematic review and meta-analysis protocol is to assess the effectiveness and safety of acupuncture therapy for treating nausea and vomiting in patients with cancer. METHODS: Three electronic databases and 2 clinical registry platforms will be searched from inception to May 2022: the MEDLINE via PubMed, Embase via Ovid, the Cochrane Central Register of Controlled Trials via the Cochrane Library, the World Health Organisation International Clinical Trials Registry Platform, and National Institutes of Health Clinical trials.gov. Search terms will include nausea, vomiting, cancer, and acupuncture. Two researchers will independently select studies, extract data and assess the risk of bias. The primary outcome will be the incidence of nausea and/or vomiting or other validated outcome measures. Meta-analysis will be carried out using RevMan V.5.4. The quality of evidence from randomized clinical trials will be evaluated with the Grading of Recommendations Assessment, Development and Evaluation System tool. RESULTS: The results will provide a high-quality synthesis of evidence for clinicians in the field of oncology. CONCLUSION: The conclusion is expected to provide evidence to determine whether acupuncture is an effective and safe treatment for cancer patients with nausea and vomiting.

OBJECTIVE: Side-effects of medications cause xerostomia. There have been cases where a medication has been discontinued owing to its severe side-effects. Therefore, the xerostomia must be treated to ensure that the primary disease is managed effectively. This study analyzed the actual status of patients with medication-induced xerostomia and investigates factors associated with its improvement. METHODS: This study assessed 490 patients diagnosed with medication-induced xerostomia who had an unstimulated salivary flow of ≤0.1 mL/min and received treatment for xerostomia at a xerostomia clinic. Patient age, sex, medical history, medications used, disease duration of xerostomia, and psychological disorders were recorded. The anticholinergic burden was assessed using the Anticholinergic Cognitive Burden scale. The unstimulated salivary flow was measured by the spitting method. According to their symptoms and diagnoses, the patients were introduced to oral lubricants, instructed on how to perform massage, and prescribed Japanese herbal medicines, and sialogogues. Factors associated with the subjective improvement of xerostomia and objective changes in the salivary flow rate were recorded at six months. RESULTS: Xerostomia improved in 338 patients (75.3%). The improvement rate was significantly lower in patients with psychiatric disorders (63.6%) (P = 0.009). The improvement rate decreased as more anticholinergics were used (P = 0.018). However, xerostomia improved in approximately 60% of patients receiving three or more anticholinergics. The unstimulated salivary flow increased significantly more in patients who reported an improvement of xerostomia (0.033±0.053 mL/min) than in those who reported no improvement (0.013±0.02 mL/min) (P = 0.025). CONCLUSION: Xerostomia treatment improved oral dryness in 75.3% of patients receiving xerogenic medications in this study. If xerostomia due to side-effects of medications can be improved by treatment, it will greatly contribute to the quality of life of patients with xerogenic medications and may reduce the number of patients who discontinue medications.

Drug-induced kidney injury has historically been associated with renal tubule injury related to small molecule pharmaceuticals such as nonsteroidal anti-inflammatory drugs, antineoplastic agents, or antibiotics, but as a greater number of alternative classes of medicines such as biotherapeutics, molecular-targeted antineoplastic drugs, chimeric antigen receptor T-cell therapies, antibody-drug conjugates, oligonucleotide therapies, or other immunomodulatory drugs come to market, the presentation of drug-induced nephrotoxicity is changing. This review article describes the potential rare clinical events in drug-induced kidney injury that might be noted with these new therapies and their potential impact on patients. Potential pathogenic mechanisms related to immunogenicity, immune complex formation, and stimulation of downstream proinflammatory pathways with some of these alternative medicine classes have resulted in the potential for glomerulonephritis, acute interstitial nephritis, renal vasculitis, and other immune-mediated renal disorders in humans. This contrasts with nonclinical toxicity studies, where biologic therapies more often result in vasculitis and glomerulonephritis associated with antidrug antibodies and immunomodulatory pharmacology, and which are not always predictive of clinical effects. While nonclinical antidrug antibody-related renal disease is generally not clinically relevant, other immune-mediated nephrotoxicities associated with immunomodulatory drugs may be predictive of clinical adverse events. Fortunately, these conditions are still rare and account for a small percentage of serious adverse events in kidneys of patients.

RATIONALE: The Chaga mushroom (Hymenochaetaceae, Inonotus obliquus) is a fungus belonging to the Hymenochaetaceae family. It is parasitic on birch and other tree species. Chaga mushrooms are rich in various vitamins, minerals, and nutrients. Some people consider these mushrooms medicinal as they have been reported to suppress cancer progression through anti-inflammatory and antioxidant effects. However, recent studies have reported that excessive ingestion of Chaga mushrooms can cause acute oxalate nephropathy. PATIENT CONCERNS: A 69-year-old man who ingested Chaga mushroom powder (10-15âg per day) and vitamin C (500âmg per day) for the past 3 months developed acute kidney injury (AKI) with the clinical manifestations of nephrotic syndrome (NS). DIAGNOSIS: Pathological findings showed focal acute tubular injury and the deposition of calcium oxalate crystals in the tubules. Light microscopy showed interstitial fibrosis and tubular atrophy, and electron microscopy showed the effacement of the foot processes in podocytes. Based on these results, the diagnosis was acute oxalate nephropathy accompanied by minimal change disease (MCD). INTERVENTIONS: The patient's kidney function did not improve with supportive care, such as hydration and blood pressure control. Thus, we recommended hemodialysis and the administration of a high dose of steroids (intravenous hydrocortisone 500âmg twice a day for 3âdays and oral prednisolone at 1âmg/kg). OUTCOMES: The patient's kidney function recovered just 1 month after the start of treatment, and the MCD was completely remitted. LESSONS: In cases of AKI with an unknown cause, it is important to closely observe the patient's medication history, and it is recommended to perform kidney biopsy. Furthermore, this study showed that active dialysis and high-dose steroid treatment can restore kidney function in patients with AKI caused by acute oxalate nephropathy with MCD.

INTRODUCTION: In Denmark, physicians are legally obliged to report serious adverse drug reactions (ADRs), such as intracranial hemorrhage (ICH) following anticoagulant (AC) treatment, to the Danish Medicines Agency. We were therefore puzzled to discover a high number of reports concerning ICHs following treatment with the direct oral anticoagulants (DOACs) dabigatran, rivaroxaban, and apixaban compared with warfarin. This was surprising, as all DOACs have been found to be associated with a lower risk of ICH compared with warfarin in phase III randomized controlled trials. OBJECTIVES: The primary aim of the study was to estimate the level of underreporting of ICH as an ADR following treatment with warfarin, dabigatran, rivaroxaban, and apixaban. METHODS: This observational study covered a 5-year period (2014-2018). Using nationwide registries held by the Danish Health Data Authority, the number of users, exposure time in person-years, and related ICH events for each of the study drugs were estimated. Data on ADR-ICH reports were extracted from the interactive ADR overviews held by the Danish Medicines Agency. RESULTS: From 2014 to 2018, 97.0% of the identified warfarin-related ICH events were not reported as ADRs. For the DOACs, the level of underreporting ranged from 88.8 to 90.8%. CONCLUSION: We found a heavy and differentiated level of underreporting of ICH as an ADR following treatment with the four study drugs.

CONTEXT: Drug-induced liver and kidney injuries are the most common adverse drug reactions in the clinic, and they have similar pathogeneses. AIMS: To analyze the clinical characteristics of patients with drug-induced liver and/or kidney injury. SETTINGS AND DESIGN: This was a retrospective study. METHODS AND MATERIALS: We analyzed data from 162 patients with drug-induced liver and/or kidney injury from 2008 to 2018 at the Chinese Rocket Force Characteristic Medical Center. Univariate and multivariate logistic analyses were performed on the drugs used, sex, age, weight, complications, and laboratory test results. Statistical analysis was performed using SPSS 25.0 statistical software. RESULTS: (1) The most common drugs causing organ injury in this study were antineoplastic drugs, antibiotics, traditional Chinese medicine, lipid-lowering drugs, and nonsteroidal anti-inflammatory drugs. (2) Among 22 patients with drug-induced liver and kidney injuries, 68.18% had a hepatocellular pattern, 13.64% had a mixed pattern, and 18.18% had a cholestatic pattern. Among the three groups, the P value for creatinine was 0.002. (3) The P value for urinary protein between the isolated kidney injury group and the liver and kidney injury group was 0.028. (4) Multivariate analysis showed that, among the drug-induced renal injury patients and all injury patients, those with a higher neutrophil percentage had a lower risk of liver injury (OR = 0.574, 95% CI: 0.390-0.846; OR = 0.545, 95% CI: 0.396-0.749). CONCLUSIONS: (1) The serum creatinine level was higher in liver injury patients with the cholestatic pattern than in those with the hepatocellular or mixed pattern. (2) There was a significant difference in urinary protein between the isolated kidney and the liver and kidney injury groups. (3) Among patients with drug-induced organ injury, those with a higher neutrophils percentage had a lower risk of liver injury.

INTRODUCTION: The Patient-Generated Subjective Global Assessment (PG-SGA) is currently the standard nutritional assessment tool for patients with cancer. In a retrospective assessment of a prospective cohort, we showed that the Nutritional Risk Index (NRI) seemed to be associated with treatment toxicity and survival in patients with metastatic colorectal cancer (mCRC). OBJECTIVE: The objective of this study was to compare these two nutritional tools (PG-SGA and NRI) on their correlation with chemotherapy-related toxicity and survival in non-pre-treated patients with mCRC. METHODS: This prospective multicentre observational study enrolled non-pre-treated patients with mCRC. PG-SGA and NRI were performed at the onset of first-line chemotherapy. Treatment-related toxicities were registered according to National Cancer Institute Common Toxicity Criteria Adverse Event version 4.0. Progression-free survival (PFS) and overall survival (OS) were calculated from the start of treatment. RESULTS: A total of 168 patients were included from eight French centres. Patients were considered malnourished in 41% of cases according to PG-SGA and 56% of cases according to the NRI. In multivariate analysis, malnutrition according to PG-SGA was significantly associated with chemotherapy-related grade ≥2 clinical toxicities (odds ratio: 3.7; 95% confidence interval [CI]: 1.7-8.4; p = 0.001) and OS (hazard ratio [HR]: 2.6; 95% CI: 1.3-5.3; p = 0.006), but not with PFS (HR: 1.5; 95% CI: 0.8-2.6; p = 0.2). Conversely, malnutrition according to the NRI was not significantly associated with these tolerance and efficacy parameters. CONCLUSION: Although more complex to perform in daily oncology practice, the PG-SGA score appears to be the best nutritional assessment tool because of its strong association with clinically relevant oncological outcomes such as OS and treatment-related toxicities in patients with mCRC.

RESUMEN • Introducción: Con el envejecimiento creciente de la población, la práctica estomatológica exige la utilización del conocimiento para identificar y tratar pacientes con enfermedades sistémicas cada vez más frecuentes, lo cual puede requerir el uso de medicamentos capaces de interactuar con el tratamiento farmacológico de su enfermedad de base. La literatura refleja esta relación de manera fragmentada y carente de un enfoque sistémico. Objetivo: Identificar en la literatura el uso de medicamentos en pacientes con riesgo quirúrgico y describir su repercusión durante el tratamiento estomatológico. Material y Métodos: Se realizó una revisión bibliográfica y se consultaron artículos científicos, tesis de titulación de especialistas, maestrías y doctorales entre otras referencias principalmente de los últimos 5 años mediante Google. Desarrollo: Se abordan las generalidades, manejo estomatológico y las interacciones medicamentosas de cada una de las enfermedades a estudiar (Diabetes Mellitus, hipertensión arterial y cardiopatía), así como las situaciones que requieren profilaxis antibiótica. Conclusiones: Los pacientes con riesgo quirúrgico utilizan medicamentos que producen interacciones importantes con fármacos como AINES, anestésicos locales y glucocorticoides que habitualmente se emplean en los tratamientos estomatológicos; existen además enfermedades sistémicas en las cuales hay que tener en cuenta la profilaxis antibiótica antes de realizar determinados procederes estomatológicos.
ABSTRACT • Introduction: With the growing of population aging, the dental practice requires the adequate knowledge to identify and treat patients with increasingly frequent systemic diseases, which may require the use of drugs capable of interacting with the pharmacological treatment of their underlying diseases. The literature reflects this relationship in a fragmented manner and lacking a systemic approach. Objective: To identify the drugs used in risk patients undergoing surgery and describe their repercussion during dental treatment. Material and Method: A bibliographic review was carried out. Scientific articles, specialists´ theses, Master´s and PhD degrees among other references were consulted, mainly the ones obtained from the search carried out in Google during the last 5 years. Results: The generalities, dental management and drug interactions between the diseases studied (diabetes mellitus, arterial hypertension and heart disease) were addressed, as well as the situations that require antibiotic prophylaxis. Conclusions: The surgical risk patients studied use drugs that produce important interactions with drugs such as NSAIDs, local anesthetics and glucocorticoids that are usually used in dental treatments. There are also systemic diseases in which antibiotic prophylaxis must be taken into account before performing certain dental procedures.

Introducción: La Organización Mundial de la Salud (OMS) recomendó el uso de la poliquimioterapia (PQT) desde 1981, y desde 1998 esta pauta de tratamiento fue introducida en Paraguay. Desde ese entonces y hasta la actualidad el esquema Multibacilar (MB) comprende tres drogas: rifampicina, clofazimina y dapsona, y, el esquema Paucibacilar (PB), dos drogas: rifampicina y dapsona. Todas ellas relacionadas en mayor o menor medida a efectos colaterales. A pesar de ello, hay pocos estudios a nivel mundial, y ningún estudio en el Paraguay. Métodos: Estudio retrospectivo, observacional, de corte transversal con componente analítico, llevado a cabo en la Cátedra de Dermatología del Hospital de Clínicas - Universidad Nacional de Asunción, en San Lorenzo, Paraguay. En el periodo de enero de 2013 a octubre de 2017. Resultados: Fueron incluidos en el estudio 58 pacientes con enfermedad de Hansen, de los cuales 45 (78%) presentaron al menos un efecto colateral a la PQT, 3 pacientes presentaron más de un efecto colateral. De los 45, 25 (56%) fueron del sexo masculino y 20 (44%) del sexo femenino. En cuanto a la distribución por rango de edad: Dos (4%) en menores de 18 años, 8 (18%) de 19 a 30 años, 27 (18%) de 31 a 59 años y 8 (18%) 60 y más años. Seis (3%) pacientes de procedencia rural y 39 (87%) de procedencia urbana. Cuarenta y siete (98%) casos de efectos colaterales hematológicos (Anemia: 45; leucopenia: 1 y trombocitopenia: 1) y 1 (2%) caso de efecto colateral gastrointestinal (hepatitis). La conducta en casos de anemia: suplementación con hierro y ácido fólico: 40, suspensión de dapsona: 10 y ninguna conducta: 6 suspensión de la dapsona en 1 caso de leucopenia, suspensión de la dapsona en 1 caso de trombocitopenia y suspensión de la rifampicina en 1 caso de hepatitis. En 26 (58%) pacientes los efectos colaterales se presentaron al mes del inicio de la PQT, en 15 (33%) pacientes entre 2 y 5 meses del inicio y en 4 (9%) pacientes a los 6 y más meses del inicio. En 14 (31%) de los pacientes con efectos colaterales existía comorbilidad y en 31 (69%) casos, eran pacientes sanos. De los 45 pacientes, 41 (91%) estaban en tratamiento MB, 4 (9%) en tratamiento PB. Conclusión: La mayoría de los pacientes incluidos en el estudio presentaron efectos colaterales. Los hombres fueron los más afectados, el rango etario en el cual se presentaron con mayor frecuencia fue entre los 31 y 59 años. La mayoría procedían del medio urbano. Los efectos colaterales más frecuentes fueron los hematológicos y, de entre ellos, la anemia. Ante tal situación la medida más frecuentemente adoptada fue la suplementación con hierro y ácido fólico. En la mayoría de los casos los efectos colaterales aparecieron en el primer mes de recibir la medicación. Aquellos pacientes que recibieron PQT MB presentaron la mayor frecuencia de efectos colaterales
Introduction: The World Health Organization (WHO) recommends the implementation of multidrug (MDT) since 1981, and this régimen was introduced in Paraguay in 1998. The MDT administrate three drugs: rifampicin, clofazimine and dapsone to multibacillary patients (MB) and only two: rifampicina and dapsone to paucibacillary patients (PB). All the drugs have some adverse effects. But very few statistics have been carried out in the world on this matter and none at all in Paraguay. Methods: The work is a retrospective, observational, cross-sectional and analytical study carried out at Catedra de Dermatología del Hospital de Clínicas-Universidad Nacional de Asunción, San Lorenzo, Paraguay between January 2013 and October 2017. Results: Fifty eight leprosy patients were registered in the study and 45 (78%) presented at least one adverse effect to the MDT and 3 patients presented more tan one. 25/45 were men and 20 (44%) women. The age distributions were: Two (4%) less than 18 years old, 8 (18%) between 19-30 years old, 27(18%) 31-59 years old and 8 (18%) 60 and older. Six (3%) lived in rural setting and 39 (87%) urban. Forty seven (98%) presented adverse hematological effects (anemia: 45, leucopenia: 1 and thrombocytopenia:1) and 1 (2%) presented a gastrointestinal effect. Forty patients with anemia received iron and folic acid supplements and 6 cases with no modifications. There was 1 case leucopenia, 1 thrombocytopenia, and 1 hepatitis due to rifampicine. In 26 patients (58%) adverse effects were detected during first month of MDT, in 15 (33%) between 2-5 of treatment and in 4 (9%) patients after 6 or more months of treatment. Fourteen (31%) patients had comorbility and 31 (69%) were healthy patients. Forty one (91%) patients were receiving MB MDT and 4 (9%) PB MDT. Conclusions: The mayority of the patients in the study presented adverse effects. Men were the most affected and the mayority were in the 31-59 years age group and from urban settings. Most of the effects were hematological and among them, anemia the most frequent. These cases were supplemented with iron and folic acid. Most adverse effects appeared during the first month of treatment and MB MDT group was the most affected

CONTEXT: : Local anesthetics (LAs) are in widespread use by dental practitioners, and erroneous administration, such as intravenously or exceeding the maximum dose, can cause the life-threatening condition of local anesthetic systemic toxicity (LAST). AIMS: The objective of the present study was evaluate the ability of dentists to recognize signs of LAST and quantify how often they have used lipids to treat LAST in dentistry patients. MATERIALS AND METHODS: The study administered 600 questionnaires that asked about the frequency with which dentists encountered LAST and the symptoms of LAST and its treatment, especially with lipids. RESULTS: The results showed that 520 (86.66%) respondents had never seen LAST, and 404 (67.3%) had no idea about lipid treatment. In addition, 128 (21.3%) had heard about lipid treatment but had inadequate knowledge of it and 59 (9.8%) had read an article about lipid treatment, but only 9 (1.5%) knew how to use lipid treatment. Finally, 80 (13.33%) participants had seen LAST but had used a treatment other than lipids. CONCLUSION: Dentists and all facilities using LA must be aware of LAST, and knowledge of lipid treatment must be increased by education. Twenty percent lipid solutions must be kept handy in their offices by dentists.

OBJETIVOS: Describir los hallazgos clínicos, de laboratorio e histopatológicos en pacientes con DRESS. MATERIALES Y MÉTODOS: Estudio retrospectivo de fichas clínicas de pacientes con DRESS entre los años 2007 y 2017 con score regiSCAR mayor o igual a caso probable. RESULTADOS: Se estudiaron 24 pacientes: 14 fueron mujeres (58,3%), 2 tuvieron enfermedad autoinmune (8,3%), la edad promedio fue 45,04 años DS 17,2 (16-78). Los medicamentos frecuentemente implicados fueron Lamotrigina (33,3%) y Carbamazepina (20,8%). La latencia fue 28 días DS 17,7 (10-90). La clínica más frecuente fue prurito 87,5%, fiebre 75%, edema facial 62,5% y adenopatías 45,8%. En laboratorio lo más alterado fueron pruebas hepáticas (70,8%) y eosinofilia (45,8%). 11 pacientes (45,8%) presentaron eosinófilos en la histopatología y 21 pacientes (87,5%) fueron tratados con corticoides. La mortalidad fue 11,1% (2 pacientes, por causas distintas a DRESS). DISCUSIÓN: DRESS es una reacción adversa a medicamentos severa con variados hallazgos clínicos y analíticos que requieren de su conocimiento para no retrasar el diagnóstico y su tratamiento.

Los trastornos funcionales del tubo digestivo, entre los que se encuentra el síndrome de intestino irritable con predominio de diarrea, constituyen una patología muy prevalente en todo el mundo, con un gran impacto tanto económico como en la calidad de vida de los pacientes, que no cuenta con alternativas terapéuticas completamente satisfactorias. Estas circunstancias han propiciado la investigación de diferentes moléculas con unas dianas terapéuticas más específicas como los receptores opioides. Eluxadoline (Vibercy(R) en Estados Unidos/Truberzi® en Europa, de Allergan) es una molécula agonista con efectos locales mixtos tanto agonista de los receptores opioides μ- y κ- como antagonista del receptor δ-opioide, que fue aprobada en 2015 por la Food and Drug Administration (FDA) y en 2016 por la Agencia Europea del Medicamento (EMA) para su indicación en el síndrome de intestino irritable con predominio de diarrea. Eluxadoline es un fármaco que ofrece, con ventaja sobre los que se utilizan en esta patología, el control tanto de la consistencia de las deposiciones como del dolor abdominal, con una buena tolerancia en la mayoría de los casos y una mejoría en la calidad de vida de estos pacientes, por lo que es una molécula a considerar en el abordaje de esta patología. Como en todo producto de reciente incorporación terapéutica, es de esperar una farmacovigilancia adecuada así como que se vaya generando conocimiento de estudios que nos ofrezcan información sobre diferentes escenarios tales como el tratamiento a demanda, la valoración de la pérdida de respuesta, la utilización del tratamiento como rescate a otras moléculas y la valoración del coste-eficacia del fármaco, para caracterizar y posicionar de una manera más precisa eluxadoline dentro del espectro terapéutico (AU)
Functional gut disorders, including diarrhea-predominant irritable bowel syndrome, are highly prevalent conditions worldwide that significantly impact health economy and patient quality of life, yet lacking fully satisfactory therapeutic options. These circumstances fostered research on various molecules with more specific therapeutic targets, including opioid receptors. Eluxadoline (Allergans Vibercy® in the USA, Truberzi® in Europe) is a locally-acting mixed mu- and kappa-opioid receptor agonist, and delta-opioid receptor antagonist, that was licensed in 2015 by the Food and Drug Administration (FDA) and in 2016 by the European Medicines Agency (EMA) for use in diarrhea-predominant irritable bowel syndrome. Eluxadoline provides, with advantage over the current standard of care, control of both stool consistency and abdominal pain, good tolerability in most cases, and improved quality of life, hence it deserves consideration when approaching a patient with this disorder. As with any recently approved therapy, adequate pharmacovigilance is to be expected, as well as studies to inform on different scenarios such as on-demand therapy, loss of response assessment, use as rescue therapy for other molecules, and cost-effectiveness, to further characterize and more accurately position eluxadoline within the therapeutic spectrum (AU)

Many cytotoxic chemotherapeutics elicit a proinflammatory response which is often associated with chemotherapy-induced behavioral alterations. The immune system is under circadian influence; time-of-day may alter inflammatory responses to chemotherapeutics. We tested this hypothesis by administering cyclophosphamide and doxorubicin (Cyclo/Dox), a common treatment for breast cancer, to female BALB/c mice near the beginning of the light or dark phase. Mice were injected intravenously with Cyclo/Dox or the vehicle two hours after lights on (zeitgeber time (ZT2), or two hours after lights off (ZT14). Tissue was collected 1, 3, 9, and 24 hours later. Mice injected with Cyclo/Dox at ZT2 lost more body mass than mice injected at ZT14. Cyclo/Dox injected at ZT2 increased the expression of several pro-inflammatory genes within the spleen; this was not evident among mice treated at ZT14. Transcription of enzymes within the liver responsible for converting Cyclo/Dox into their toxic metabolites increased among mice injected at ZT2; furthermore, transcription of these enzymes correlated with splenic pro-inflammatory gene expression when treatment occurred at ZT2 but not ZT14. The pattern was reversed in the brain; pro-inflammatory gene expression increased among mice injected at ZT14. These data suggest that inflammatory responses to chemotherapy depend on time-of-day and are tissue specific.

The internal clock located in the suprachiasmatic nuclei of the anterior hypothalamus is controlled by external (environment and social life) and genetic factors. Desynchronisation of the organism occurs when the clock does no longer work in harmony with the environ- mentalfactors. Rhythm desynchronization can be related to a conflict between the clock and environmentalfactors (shift work, night shift, transmeridianflight), to inefficient synchro- nizers (aging, psychiatric diseases..), to badly received synchronizers (circadian rhythm sleep disorders with e.g delayed or advanced sleep phase syndromes), or to the use of some drugs (lithium, propofol, alcohol...). In the long term rhythm desynchronisation can result in serious illnesses and the use of resynchronizing agents like melatonin or bright light are useful to the clock resynchronization.
