Background: While several studies have noted smell impairment in schizophrenia, it is unclear whether this impairment extends to acute psychosis and whether it is associated with more severe illness as expressed in extended hospitalization.

Objectives: To evaluate the olfactory function of patients in an acute psychotic state and correlate it with clinical symptomatology and length of hospitalization.

Methods: Olfactory function was assessed in 20 patients with schizophrenia in their first week of hospital admission for acute psychosis compared with matched controls. Olfaction was evaluated via three stages: threshold, discrimination, and identification of different odors utilizing the Sniffin' Sticks test battery.

Results: Schizophrenia patients scored significantly lower on total smell score, discrimination, and identification abilities. A significant association was observed between hospitalization duration and total smell score and smell discrimination. No significant associations between smell and clinical symptomatology were observed.

Conclusions: Study observations confirm impaired sense of smell in schizophrenia patients and suggest that smell impairment may be a potential marker of more serious illness as expressed in longer hospital stay.

Background: Previously described as a subcategory of obsessive compulsive disorder (OCD), hoarding disorder was added to the fifth Diagnostic and Statistical Manual of Mental Disorders (DSM-V) as a stand-alone diagnosis for the first time. The first formal research in the 1990s surprisingly found no connection between material deprivation early in life and hoarding; however, later studies linked early traumatic life experiences with hoarding. Subsequent familial studies demonstrated a genetic predisposition for hoarding. Emerging evidence suggests a link between a post-traumatic stress disorder (PTSD) and hoarding in Jewish Holocaust survivors.

Objectives: To evaluate the literature on PTSD among Jewish Holocaust survivors for associations between PTSD and hoarding.

Methods: A systematic search of selected databases, including PubMed, Google Scholar, NCBI, Psych Info, and EBSCO Host was conducted from 1 March 2017 to 15 July 2018 using the following search terms: hoarding, hoarding disorder, obsessive compulsive disorder, OCD, compulsive hoarding, Jewish Holocaust survivors, Shoa, post-traumatic stress disorder, and PTSD. Inclusion criteria included peer reviewed research published on adults in English since 1990. Because no publications linking hoarding and PTSD in Jewish Holocaust survivors were found, references in retained papers were also searched for any relevant published work.

Results: Seven articles linking PTSD and hoarding were identified for this review. However, no articles were found linking PTSD and hoarding in Jewish Holocaust survivors.

Conclusions: A relationship between PTSD and hoarding in Jewish Holocaust survivors is conceivable and should be explored to effectively diagnose and care for affected individuals.

Background: Standardization of the dietetic care process allows for early identification of malnutrition and metabolic disorders, interdisciplinary collaboration among the medical team, and improved quality of patient care. Globally, dietitians are adopting a nutrition care model that integrates national regulations with professional scope of practice. Currently, Israel lacks a standardized dietetic care process and documentation terminology.

Objectives: To assess the utilization of a novel sectoral documentation system for nutrition care in Israel.

Methods: Seventy dietitians working in 63 geriatric facilities completed an online training program presenting the proposed patient-sectoral-model. Training was followed by submission of sample case studies from clinical practice or completion of a case simulation. Application of the proposed model was assessed by measuring the frequency participants implemented different sections of the model and responses to an approval questionnaire.

Results: Fifty-four participants (77%) provided completed cases. Over 80% of participants reported each step of the proposed dietary care process with 100% reporting the “nutrition diagnosis”. Fifty-one dietitians (72.8%) completed the approval survey with the section on nutrition diagnosis receiving a highly favorable response (95%), indicating that the new documentation system was beneficial. Over 80% of participants rated the model useful in clinical practice.

Conclusions: A sectoral approach for documenting dietetic care may be the ideal model for dietitians working in specific patient populations with the potential for improving interdisciplinary collaboration in patient care.

Background: Anti-ribosomal-P antibodies have been associated with central nervous manifestations of systemic lupus erythematosus. However, inconsistencies in their prevalence and clinical correlations have become an obstacle to their use as a diagnostic marker of the disease. This lack of consistency might stem from several factors, such as the lag period between clinical manifestations and the time blood was drawn, or the different methods used for antibodies detection.

Objectives: To evaluate three different enzyme-linked immunosorbent assay tests for the detection of anti-Rib-P Abs[1] in patients with SLE[2] and normal controls.

Methods: Sera from 50 SLE outpatients and 50 healthy subjects were tested with three ELISA[3] kits: Kit-1, which uses synthetic peptide comprising the 22 C-terminal amino-acids; Kit-2, which uses native human ribosomal proteins (P0, P1, P2); and Kit-3, which is coated with affinity-purified human ribosomal proteins. ELISA studies were performed according to the manufacturers' instructions.

Results: The prevalence of anti-Rib-P Abs in SLE patients and controls was 30% vs. 0%, 17% vs. 21%, and 30% vs. 14% in kits 1-3 respectively. Anti-Rib-P Abs detected by Kit-1 correlated with the SLEDAI score (SLE Disease Activity Index). No correlation between prior CNS[4] manifestations and anti-Rib-P Abs was observed.

Conclusions: A significant difference was documented between the ELISA kits used for the detection of anti-Rib-P Abs. A correlation was found between these antibodies (evaluated by Kit-1) and concurrent SLEDAI scores, in contrast to the lack of correlation with previous CNS manifestations. This supports the notion of "active serology" that is evaluated at the same time manifestations are present, as well as the need for standardization of laboratory assays in the future that enable a better assessment of anti-Rib-P Abs presence and clinical correlation. 

Primary biliary cirrhosis is an autoimmune cholestatic liver disease characterized by humoral and cellular response directed at mitochondrial autoantigens, mainly the E2 component of the pyruvate dehydrogenase complex. The etiology of PBC[1], like most polygenic autoimmune diseases, belongs to the "complex" category, including genetic elements and environmental factors. Many environmental factors, such as xenobiotics, smoking, hormonal therapy, toxins, oxidative stress and recurrent urinary tract infections, are associated with PBC. Infectious agents can trigger autoimmunity via several mechanisms and are associated with various autoimmune diseases. A relationship between PBC and several infectious agents, and a possible role for Escherichia coli in the pathogenesis of PBC has been suggested. The identification of a culprit agent that induces or exacerbates PBC might have diagnostic and therapeutic implications. This review evaluates the evidence for an infectious agent role in the pathogenesis of PBC.
