Physical Health in Early and Late Stages of Bipolar Disorder

Introduction

Bipolar disorder (BD) is related to high prevalence of somatic comorbidities, health care costs, and premature mortality [1]. Some evidence supports the view of BD as chronic, progressive and multisystem disorder in which not only mental system, but also somatic systems are involved [2].

Aim

To investigate differences in physical health in patients with bipolar disorder at different stages (early vs. late) of the disease.

Methods

Cross-sectional, naturalistic, multicenter study. Sample: 110 outpatients with BD [68 early stage (diagnosed at least 5 years earlier) and 42 late stage (at least 20 years earlier)]. Assessment: demographic and clinical variables; psychopathology: HDRS, YMRS and CGI; biological information: anthropometric, vital signs and lab results.

Results

Early stage group: mean age 40.1 (11.9), 66.2% females and CGI = 3.6 (1.4). Late stage group: mean age 55.8 (8.2), 69.0% females and CGI = 4.0 (1.4). Patients in early stage have significantly higher levels of glucose (t = −4.007, P < 0.001), urea (t = −2.724, P = 0.008), creatinine (F = 0.560, P = 0.022), triglycerides (t = −3.501, P = 0.001), Fe (t = 2.871, P = 0.005) and insulin (t = −3.223, P = 0.002). Moreover, they have higher Body Max Index (BMI) (t = −3.728, P < 0.000), abdominal circumference (t = −4.040, P < 0.000) and greater number of somatic comorbidities (t = −2.101, P = 0.041).

Conclusions

– patients with bipolar disorders in late stages have worse physical health than those in early stage.

– these results could be an indication that bipolar disorder might better viewed as a multisystem disorder.

Optoacoustic response of gold nanorods in soft phantoms using high-power diode laser assemblies at 870 and 905 nm

In the present paper we show the optoacoustic (OA) response of two solutions of gold nanorods dispersed in distilled water (0.8 mg/ml) and hosted in tissue-like phantoms by using small arrays of high-power diode lasers [corrected] at 870 and 905 nm as excitation sources. The high-power diode lasers [corrected] are coupled to a 7-to-1 optical fiber bundle with output diameter of 675 μm. Each solution of gold nanorods exhibits an absorption peak close to the operating wavelength, i.e. ~860 nm and ~900 nm, respectively, to optimize the generation of OA signals. The phantoms are made of agar, intralipid and hemoglobin to simulate a soft biological tissue with reduced properties of scattering. Three 3-mm diameter tubes done in the phantoms at different depths (0.9 cm, 1.8 cm, and 2.7 cm) have been filled with gold nanorods. In this way, OA signals with appreciable SNR are generated at different depths in the phantoms. The high OA response exhibited by gold nanorods suggests their application in OA spectroscopy as exogenous contrast agents to detect and monitor emerging diseases like metastasis and arteriosclerotic plaques.

Antihypertensive effects of oleuropein-enriched olive leaf extract in spontaneously hypertensive rats

The effects of chronic consumption of oleuropein-enriched (15% w/w) olive leaf extract (OLE) on blood pressure, endothelial function, and vascular oxidative and inflammatory status in spontaneously hypertensive rats (SHR) were evaluated. Ten Wistar Kyoto rats (WKY) and twenty SHR were randomly assigned to three groups: a control WKY group, a control SHR group and a SHR group treated with OLE (30 mg kg(-1)) for 5 weeks. Long-term administration of OLE reduced systolic blood pressure, heart rate, and cardiac and renal hypertrophy. OLE treatment reversed the impaired aortic endothelium-dependent relaxation to acetylcholine observed in SHR. OLE restored aortic eNOS phosphorylation at Ser-1177 and Thr-495 and increased eNOS activity. OLE eliminated the increased aortic superoxide levels, and reduced the elevated NADPH oxidase activity, as a result of reduced NOX-1 and NOX-2 mRNA levels in SHR. OLE reduced the enhanced vascular TLR4 expression by inhibition of mitogen-activated protein kinase (MAPK) signaling with the subsequent reduction of proinflammatory cytokines. In conclusion, OLE exerts antihypertensive effects on genetic hypertension related to the improvement of vascular function as a result of reduced pro-oxidative and pro-inflammatory status.

Identification of the Photoreceptor Transcriptional Co-Repressor SAMD11 as Novel Cause of Autosomal Recessive Retinitis Pigmentosa

Retinitis pigmentosa (RP), the most frequent form of inherited retinal dystrophy is characterized by progressive photoreceptor degeneration. Many genes have been implicated in RP development, but several others remain to be identified. Using a combination of homozygosity mapping, whole-exome and targeted next-generation sequencing, we found a novel homozygous nonsense mutation in SAMD11 in five individuals diagnosed with adult-onset RP from two unrelated consanguineous Spanish families. SAMD11 is ortholog to the mouse major retinal SAM domain (mr-s) protein that is implicated in CRX-mediated transcriptional regulation in the retina. Accordingly, protein-protein network analysis revealed a significant interaction of SAMD11 with CRX. Immunoblotting analysis confirmed strong expression of SAMD11 in human retina. Immunolocalization studies revealed SAMD11 was detected in the three nuclear layers of the human retina and interestingly differential expression between cone and rod photoreceptors was observed. Our study strongly implicates SAMD11 as novel cause of RP playing an important role in the pathogenesis of human degeneration of photoreceptors.

[Medical treatment of symptoms associated with double J catheters: Scientific evidence.]

Double J stents are used in Urology in an important number of pathologies. These devices contribute to solve very prevalent pathologies such as upper urinary tract lithiasis. However, there are very frequent symptoms associated with double J catheters that may produce a very important constraint on the quality of life of patients. Although theses symptoms are not severe in most cases, they require medical treatment to be solved in certain patients. Several types of drugs such as analgesics, anti-inflammatories, antibiotics, anticholinergics and alpha-blockers have been used for this pathology, with variable results depending on the authors. We consider the use of certain drugs may help patients to solve the symptoms associated with double J catheters, mainly the first days after insertion. In the mid term, urinary symptoms are associated with problems related to double J catheter, so it is necessary to establish the proper measures to have this devices not loose their physical characteristics, that may condition these adverse symptoms.

Flavonoid and lignan intake and pancreatic cancer risk in the European prospective investigation into cancer and nutrition cohort

Despite the potential cancer preventive effects of flavonoids and lignans, their ability to reduce pancreatic cancer risk has not been demonstrated in epidemiological studies. Our aim was to examine the association between dietary intakes of flavonoids and lignans and pancreatic cancer risk in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. A total of 865 exocrine pancreatic cancer cases occurred after 11.3 years of follow-up of 477,309 cohort members. Dietary flavonoid and lignan intake was estimated through validated dietary questionnaires and the US Department of Agriculture (USDA) and Phenol Explorer databases. Hazard ratios (HR) and 95% confidence intervals (CIs) were calculated using age, sex and center-stratified Cox proportional hazards models, adjusted for energy intake, body mass index (BMI), smoking, alcohol and diabetes status. Our results showed that neither overall dietary intake of flavonoids nor of lignans were associated with pancreatic cancer risk (multivariable-adjusted HR for a doubling of intake = 1.03, 95% CI: 0.95-1.11 and 1.02; 95% CI: 0.89-1.17, respectively). Statistically significant associations were also not observed by flavonoid subclasses. An inverse association between intake of flavanones and pancreatic cancer risk was apparent, without reaching statistical significance, in microscopically confirmed cases (HR for a doubling of intake = 0.96, 95% CI: 0.91-1.00). In conclusion, we did not observe an association between intake of flavonoids, flavonoid subclasses or lignans and pancreatic cancer risk in the EPIC cohort.

Cerebellar atrophy supporting diagnosis of alcohol dependence: A case report

Chronic use of alcohol is a known cause of cerebellar atrophy. This finding could be a valuable diagnosis support when there are not other information sources. In this case report, we describe a 65-year-old male patient who was referred from primary care to specialized consultation because a depressive syndrome it was unresponsive to treatment with desvenlafaxine and lorazepam. In psychopathological exploration we found overvalued ideas of suffering some kind of injury and damage by the family, which oriented the diagnostic hypothesis of delusional disorder with secondary mood symptoms, although the clinical suspicion of abuse of alcohol was proposed as a differential diagnosis. The continuing minimization and denial of consumption by the patient as well as their reluctance to incorporate an external informant made that the workup was a key element to elucidate the diagnosis. We found a discrete increase in transaminases, gamma glutamyl transferase and alkaline phosphatase. Magnetic resonance imaging showed cerebellar atrophy (vermian and, in a lesser extent, in both hemispheres). Once the patient was confronted with these results, he agreed to disclose his problem, which fulfilled alcohol dependence criteria. After that, he accepted to initiate treatment and detoxification in a specialized unity.

Conclusions

Although psychiatric diagnosis is based on the clinical features and the exclusion of associated medical conditions, in this case the workup provided support to our clinical suspicion, favouring recognition of the problem and willingness to treatment by the patient.

Posterior vitreous detachment and electroconvulsive therapy: Insights from a case

A case of bilateral posterior vitreous detachment after electroconvulsive therapy (ECT) has been reported previously in the literature. There is not enough evidence about ocular side effects of this treatment. The literature supports a slight increase in intraocular pressure (IOP), although no ocular complications have been reported in normal, glaucomatous or postsurgical eyes. In this case report, we describe a 73-year-old female patient suffering a recurrent depressive disorder, who was admitted to acute psychiatric unit because a treatment-resistant major depressive episode (after an adequate trial of antidepressant drugs and transcranial magnetic stimulation) and clinical suspicion of visual delusions by her reference psychiatrist. The nonpsychiatric history consisted of hypertension, glaucoma and ulcerative colitis in treatment with azathioprine and mesalazine. After a careful examination in the emergency room, we consulted to ophthalmologist because miodesopsias and glaucoma history. The IOP was normal, but a bilateral posterior vitreous detachment (PVD) was identified. Because this entity is not an absolute contraindication for ECT, and there is scarce evidence, we informed the patient and her family. After that, and through informed consent, we decided to undergo ECT. After fourteen sessions, the patient could be discharged because significant clinical benefit and no ocular complications. Outpatient continuation ECT was indicated.

Conclusions

ECT can be a safe treatment choice in cases of PVD.

Addictive behaviour and bariatric surgery: Case report and literature review

Even though the scientific evidence supports the benefits of bariatric surgery, its indications and contraindications must be continually revised in order to avoid psychiatric complications. Substance use is more common in patients subjected to bariatric surgery than in the general population. There are reports of increased incidence of alcohol abuse in patients after bariatric surgery.

Objective

To review the available evidence, after treat the case of a 50-year-old man with addiction history whose addictive behaviour worsened after undergoing bariatric surgery, with decreased tolerance to alcohol effect and increase of the intake, as well as changes in the graduation of alcohol used (including antiseptic). As a result, a dangerous revolving door that led him to repeated admissions, including Intensive Care Unit.

Results

The case is consistent with the literature that suggests that there is an increased risk of later alcohol-related problems after bariatric surgery. This risk is higher several years post surgery, in patients with previous history of problems related to alcohol, young, men, and Roux-en-Y Gastric Bypass procedure.

Conclusions

The indications for bariatric surgery should thoroughly consider the history of addiction, an adequate assessment of the patient's mental status and psychoeducation about the possible psychiatric side effects, in order to develop preventive strategies.

Dual time-point (18)F-FDG PET/CT to assess response to radiofrequency ablation of lung metastases

AIM

To establish the usefulness of dual time-point PET/CT imaging in determining the response to radiofrequency ablation (RFA) of solitary lung metastases from gastrointestinal cancer.

MATERIALS AND METHODS

This prospective study included 18 cases (3 female, 15 male, mean age 71±15 yrs) with solitary lung metastases from malignant digestive tract tumors candidates for RFA. PET/CT images 1h after injection of 4.07MBq/kg of (18)F-FDG (standard images) were performed at baseline, 1 month, and 3 months after RFA. PET/CT images 2h after injection centered in the thorax at 1 month after RFA were also performed (delayed images). A retention index (RI) of dual time-point images was calculated as follows: RI=(SUVmax delayed image-SUVmax standard image/SUVmax standard image)*100. Pathological confirmation of residual tumor by histology of the treated lesion was considered as local recurrence. A negative imaging follow-up was considered as complete response.

RESULTS

Local recurrence was found in 6/18 lesions, and complete response in the remaining 12. The mean percentage change in SUVmax at 1 month and at 3 months showed a sensitivity and specificity for PET/CT of 50% and 33%, and 67% and 92%, respectively. The RI at 1 month after RFA showed a sensitivity and specificity of 83% and 92%, respectively.

CONCLUSIONS

Dual time point PET/CT can predict the outcome at one month after RFA in lung metastases from digestive tract cancers. The RI can be used to indicate the need for further procedures to rule out persistent tumor due to incomplete RFA.
