Risk assessment of biological hazards in University laboratories: checklist and critical control points.

Results: The results highlighted that 40 laboratories fall into the "low risk" and the remaining 2 into the "moderate risk" category. Conclusions: Labs with risk factors are a minority. These were properly identified using the proposed methodology. Background and aim: Biomedical research in academic settings is an important issue for Public Health and Environment protection. As workplaces, the facilities for research expose their personnel to different hazards and health risks. The University of L'Aquila (Italy) carried out a field study aimed at creating and applying a checklist intended for laboratory staff. Methods: The proposed checklist was derived from the procedure illustrated in the Appendix (procedure followed for the identification of a numerical index of biological risk for university facilities) and consists of 9 items. The study was conducted in 42 laboratories.

The SASE1 X-ray beam transport system.

SASE1 is the first beamline of the European XFEL that became operational in 2017. It consists of the SASE1 undulator system, the beam transport system, and the two scientific experiment stations: Single Particles, Clusters, and Biomolecules and Serial Femtosecond Crystallography (SPB/SFX), and Femtosecond X-ray Experiments (FXE). The beam transport system comprises mirrors to offset and guide the beam to the instruments and a set of X-ray optical components to align, manipulate and diagnose the beam. The SASE1 beam transport system is described here in its initial configuration, and results and experiences from the first year of user operation are reported.

Species and antimicrobial susceptibility testing of coagulase-negative staphylococci in periprosthetic joint infections.

The objective was to evaluate the distribution of coagulase-negative staphylococci (CNS) involved in periprosthetic-joint infections (PJIs) and to describe their susceptibility profile to antibiotics. We conducted a multicentre retrospective study in France, including 215 CNS PJIs between 2011 and 2015. CNS PJIs involved knees in 54% of the cases, hips in 39%, other sites in 7%. The distribution of the 215 strains was: Staphylococcus epidermidis 129 (60%), Staphylococcus capitis 24 (11%), Staphylococcus lugdunensis 21 (10%), Staphylococcus warneri 8 (4%), Staphylococcus hominis 7 (3%), Staphylococcus haemolyticus 7 (3%). More than half of the strains (52.1%) were resistant to methicillin, 40.9% to ofloxacin, 20% to rifampicin. The species most resistant to antibiotics were S. hominis, S. haemolyticus, S. epidermidis, with 69.7% of the strains resistant to methicillin and 30% simultaneously resistant to clindamycin, cotrimoxazole, ofloxacin and rifampicin. No strain was resistant to linezolid or daptomycin. In this study on CNS involved in PJIs, resistance to methicillin is greater than 50%. S. epidermidis is the most frequent and resistant species to antibiotics. Emerging species such S. lugdunensis, S. capitis and Staphylococcus caprae exhibit profiles more sensitive to antibiotics. The antibiotics most often active in vitro are linezolid and daptomycin.

NaCl concentration in the medium modulates the secretion of active EmpA protease in Vibrio anguillarum at post-transcriptional level.

AIMS: This study focused on the influence of different amounts of NaCl in the medium in Vibrio anguillarum EmpA protease production at both the transcriptional and post-transcriptional levels. METHODS AND RESULTS: Vibrio anguillarum 975/I was cultivated in cM9 medium with varying concentrations of NaCl: 0·5, 1·5, 3·0%. EmpA protease was monitored in the supernatants by the skim milk test, azocasein assay and Western blot analysis. The empA gene expression was measured by real-time PCR. A mutant strain 975/I defective for the empA gene confirmed the specificity of the response for EmpA protease. Active protease production was induced by 0·5 and 1·5% NaCl-amended media; however, the strain cultivated in 3·0% NaCl was unable to secrete EmpA protease. The quantitative expression of the empA gene was very similar in all tested conditions. CONCLUSIONS: The NaCl concentration in the medium modulates the secretion of active EmpA protease in V. anguillarum at a post-transcriptional level. SIGNIFICANCE AND IMPACT OF THE STUDY: EmpA protease is one of the most important virulence factors in V. anguillarum. We demonstrated the influence of osmotic changes in the regulation of EmpA protease in the V. anguillarum 975/I strain. This finding has an important impact on the evaluation of factors determining the onset of disease in fish.

Identification of novel NOTCH1 mutations: increasing our knowledge of the NOTCH signaling pathway.

BACKGROUND: Alterations in the NOTCH1 signaling pathway are found in about 60% of pediatric T-ALL, but its impact on prognosis remains unclear. PROCEDURE: We extended the previously published CoALL cohort (n = 74) to a larger cohort (n = 127) and additionally included 38 Argentine patients from ALL IC-BFM to potentially identify novel mutations and decipher a stronger discriminatory effect on the genotype/phenotype relationship with regard to early treatment response and long-term outcome. RESULTS: Overall, 101 out of 165 (61.2%) T-ALL samples revealed at least one NOTCH1 mutation, 28 of whom had combined NOTCH1 and FBXW7 mutations. Eight T-ALL samples (4.8%) exclusively revealed FBXW7 mutations. Fifty-six T-ALL (33.9%) exhibited a wild-type configuration of either gene. Four novel NOTCH1 mutations were identified localized in the C-terminal PEST domain, in the rarely affected LNR repeat domain and in the ankyrin domain. Novel LNR mutations may contribute to a better understanding of the structure of the NOTCH1 negative regulatory region (NRR) and the R1946 mutation in the ankyrin domain may represent an unusual loss-of-function mutation. CONCLUSIONS: Overall, NOTCH1 pathway mutations did not affect the relapse rate and outcome of the extended T-ALL cohort uniformly treated according to CoALL protocols, although NOTCH1 mutations were associated with good response to induction therapy (P = 0.009). Individually, HD and PEST domain mutations might exert distinct functional effects on cellular homeostasis under treatment NOTCH1 pathway activity with prognostic implications.

Selective excavation and ozone therapy: new frontier of mini-invasive caries treatment in MIH paediatric patients. A case report.

BACKGROUND: The term hypomineralisation of molars and incisors (MIH), introduced in 2001 by Weerheijm et al., describes a clinical state of hypomineralisation of permanent molars with frequent involvement of the incisors. MIH is considered a global dental problem with a prevalence ranging from 2.4% to 40.2% in the entire world paediatric population. The continuous increase in the prevalence of enamel anomalies, including MIH, indicates the need to define new intervention protocols based on the technological advances that are revolutionising paediatric dentistry. The use of ozone associated with the selective and minimally invasive excavation of the dental tissue combines the antibacterial properties of the gas with an ultra-conservative approach aimed at the maximum conservation of the dental tissue. The operative protocol described can be an important tool in the prevention and treatment of MIH. The aim of this work is to illustrate an operative clinical protocol based on the combined use of selective excavation and ozone for the treatment of carious lesions in paediatric patients with MIH.

A mouse model for hereditary thyroid dysgenesis and cleft palate.

Alteration of thyroid gland morphogenesis (thyroid dysgenesis) is a frequent human malformation. Among the one in three to four thousand newborns in which congenital hypothyroidism is detected, 80% have either an ectopic, small and sublingual thyroid, or have no thyroid tissue. Most of these cases appear sporadically, although a few cases of recurring familial thyroid dysgenesis have been described. The lack of evidence for hereditary thyroid dysgenesis may be due to the severity of the hypothyroid phenotype. Neonatal screening and early thyroid hormone therapy have eliminated most of the clinical consequences of hypothyroidism such that the heritability of this condition may become apparent in the near future. We have recently cloned cDNA encoding a forkhead domain-containing transcription factor, TTF-2, and have located the position of the gene, designated Titf2, to mouse chromosome 4 (ref. 3). Titf2 is expressed in the developing thyroid, in most of the foregut endoderm and in craniopharyngeal ectoderm, including Rathke's pouch. Expression of Titf2 in thyroid cell precursors is down-regulated as they cease migration, suggesting that this factor is involved in the process of thyroid gland morphogenesis. Here we show that Titf2-null mutant mice exhibit cleft palate and either a sublingual or completely absent thyroid gland. Thus, mutation of Titf2-/- results in neonatal hypothyroidism that shows similarity to thyroid dysgenesis in humans.

Is there a role for adjuvant therapy in radiation-induced angiosarcoma of the breast? A case report and review of the literature.

BACKGROUND: Angiosarcoma (AS) of the breast is very rare, accounting for 1% of all soft tissue breast tumors. AS may present as primary tumors of the breast or as secondary lesions usually associated with previous radiotherapy. Commonly, secondary AS affects older women (median age 67-71 years) with a clinical history of breast cancer. The preferred site of onset of RIAS is the edge of radiation fields, where radiation doses and tumor necrosis may be heterogeneous, resulting in a DNA damage and instability. Radical surgery is the treatment of choice, but no clear consensus exists on surgical management of breast AS. CASE REPORT: We describe an atypical case of relapsed RIAS after radical mastectomy, treated with new surgery and, considering the higher risk of recurrence, subsequent adjuvant chemotherapy with weekly paclitaxel. CONCLUSIONS: The frequency of radiation-induced angiosarcomas (RIAS) after breast-conserving surgery and radiotherapy has been increased to 0.14-0.5% among long survivors. Nevertheless, even if RIAS continues to be prognostically an extremely unfavorable cancer due to a high rate of recurrence, distant spread, and median overall survival (OS) of about 60 months, the benefits of loco-regional breast radiotherapy are clearly higher than the risk in developing angiosarcoma.

Art therapy as a comprehensive complementary treatment for Parkinson's disease.

Introduction: Parkinson's disease (PD) is the second most prevalent neurodegenerative disease. Complementary and alternative therapies are increasingly utilized to address its complex multisystem symptomatology. Art therapy involves motoric action and visuospatial processing while promoting broad biopsychosocial wellness. The process involves hedonic absorption, which provides an escape from otherwise persistent and cumulative PD symptoms, refreshing internal resources. It involves the expression in nonverbal form of multilayered psychological and somatic phenomena; once these are externalized in a symbolic arts medium, they can be explored, understood, integrated, and reorganized through verbal dialogue, effecting relief and positive change. Methods: 42 participants with mild to moderate PD were treated with 20 sessions of group art therapy. They were assessed before and after therapy with a novel arts-based instrument developed to match the treatment modality for maximum sensitivity. The House-Tree-Person PD Scale (HTP-PDS) assesses motoric and visuospatial processing-core PD symptoms-as well as cognition (thought and logic), affect/mood, motivation, self (including body-image, self-image, and self- efficacy), interpersonal functioning, creativity, and overall level of functioning. It was hypothesized that art therapy will ameliorate core PD symptoms and that this will correlate with improvements in all other variables. Results: HTP-PDS scores across all symptoms and variables improved significantly, though causality among variables was indeterminate. Discussion: Art therapy is a clinically efficacious complementary treatment for PD. Further research is warranted to disentangle causal pathways among the aforementioned variables, and additionally, to isolate and examine the multiple, discrete healing mechanisms believed to operate simultaneously in art therapy.

Dramatic response to regorafenib in early glioblastoma progression: case report and review of the literature.

BACKGROUND: Glioblastoma (GBM) is a highly lethal disease despite integrated treatment comprising radiotherapy plus concomitant and adjuvant temozolomide, with a median overall survival of less than 15 months. For recurrent glioblastoma, there is yet no standard therapy, considering that Bevacizumab have failed to improve overall survival (OS) while regorafenib had a little benefit over standard chemotherapy. In addition, the disease control rate is almost exclusively stability, with a poor objective response rate. CASE REPORT: Here we present a case of rapid response to regorafenib in early glioblastoma progression at the end of adjuvant radiotherapy: after a single cycle of regorafenib the patient observed an impressive improvement in clinical condition, disappearance of headaches and a clear reduction of neoplastic tissue in MRI. A brief review about new radiological patterns in Magnetic Resonance Imaging (MRI) related to the introduction in clinical practice of antiangiogenic drugs and tyrosine kinase inhibitors has also been carried out. CONCLUSIONS: Regorafenib was certainly a first turning point in the second-line treatment of GBM, showing longer response rates and mostly disease stability than bevacizumab. A switch-maintenance strategy with tyrosine kinase inhibitors may represent a valid second-line therapeutic option.

[Adhesion the vaccination against HPV in ASL of L'Aquila]. / Adesione alla vaccinazione contro l'HPV nella ASL dell'Aquila.

Sexually transmitted human papillomaviruses (HPVs) are responsible for anogenital infections and tumours. Types 16 and 18 cause 70% of cervical carcinomas, the incidence of which is higher among young women. The aim of this study was to evaluate the propensity of mothers to have their 12-year-old daughters vaccinated against HPV and identify the variables that may influence their agreement, such as their kowledge of HPV and its relationship with cervical cancer. A 17-item questionnaire was anonymously administered to 312 mothers of girls born in 1997 who were invited to undergo vaccination by their local health authority. The results were analysed using the chi-squared test and STATA 9 statistical software. The analysis showed that 69% of the mothers had had their daughters vaccinated, that most of them know about HPV but only 20% clearly understood the relationship between HPV and cancer Acceptance of the vaccination seems to be associated more with a general predisposition to vaccinate than with a knowledge of HPV and its causal relationship with cervical carcinoma. This indicates a need for educational/ information programmes before and during the vaccination cycle.

[Hypothalamic syndrome as an unusual presentation of CNS relapse of acute lymphoblastic leukemia in children: report of 4 cases]. / Síndrome hipotalámico como presentación inusual de recaída en el sistema nervioso central de leucemia linfoblástica aguda en niños: reporte de 4 casos.

Acute lymphoblastic leukemia (ALL) is the most common malignancy in childhood, corresponding to 23 % of cancer in children younger than 15 years old. About 20 % of ALL cases will relapse, commonly in the bone marrow. Extramedullar relapses are unusual, and the two most frequent locations are CNS and testicles. ALL relapses, when diagnosed in the CNS, frequently present with clinical features of a meningeal syndrome. The hypothalamic syndrome, consisting of hyperphagia, obesity and / or behavior disturbances, corresponds to an unusual presentation of relapses in this location and should alert pediatricians to suspect it. We describe 4 ALL cases of hypothalamic syndrome at the time of CNS relapse.

La leucemia linfoblástica aguda (LLA) es la patología oncológica más frecuente en pediatría, y corresponde al 23 % de las neoplasias en menores de 15 años. Alrededor del 20 % de los pacientes con LLA presentan recaídas, en la mayoría de los casos, en la médula ósea. Las recaídas extramedulares son inusuales y las dos localizaciones más frecuentes son el sistema nervioso central (SNC) y los testículos. Cuando las recaídas ocurren en el SNC, suelen manifestarse con un síndrome meníngeo. El síndrome hipotalámico se define como la presencia de hiperfagia, obesidad y/o cambios en el estado de ánimo, y es una forma de presentación clínica inusual de las recaídas en el SNC y debe alertar al pediatra para mantener un alto índice de sospecha. Se describen cuatro casos que se presentaron con síndrome hipotalámico al momento de desarrollar una recaída de LLA en el SNC.

Obesity in the elderly.

Obesity is a prevalent health disease among the elderly as it contributes to the early onset of chronic morbidity and functional impairment and is also related to premature mortality. The prevalence of sarcopenic-obesity increases too with age in each sex leading to a significantly higher prevalence of physical impairment and disability, as well as higher prevalence of metabolic syndrome. We observe a natural phenomenon (ageing) and a complex world-wide illness (obesity) that should not be merely treated as the sum of the treatments for the elderly and for the obese. The balance between the potential benefits of treatment interventions, reducing premature morbidity and mortality, and the impact on quality of life in old age may be different from young and adult age in case of obesity and need to be seriously considered.

Opiate-induced persistent pronociceptive trigeminal neural adaptations: potential relevance to opiate-induced medication overuse headache.

Medication overuse headache (MOH) is a challenging, debilitating disorder that develops from the frequent use of medications taken for the treatment of migraine headache pain. MOH affects an estimated 3-5% of the general population. The mechanisms underlying the development of MOH remain unknown. Opiates are one of the major classes of medications used for the treatment of migraine at least in some countries, including the USA. Although the effects of repeated opiate use for headache are unknown, it is possible that opiate use may contribute to increased frequency and occurrence of such headaches. Recent preclinical studies exploring the neuroadaptive changes following sustained exposure to morphine may give some insights into possible causes of MOH. Peripherally, these changes include increased expression of calcitonin gene-related peptide (CGRP) in trigeminal primary afferent neurons. Centrally, they include increased excitatory neurotransmission at the level of the dorsal horn and nucleus caudalis. Critically, these neuroadaptive changes persist for long periods of time and the evoked release of CGRP is enhanced following morphine pretreatment. Stimuli known to elicit migraine, such as nitric oxide donors or stress, produce hyperalgesia in morphine- but not in saline-pretreated rats even long after the discontinuation of the opiate. CGRP plays a prominent role in initiating vasodilation of the intracranial blood vessels and subsequent headache. Furthermore, studies have demonstrated increased excitability of the nociceptive pathway in migraine sufferers, and CGRP receptor antagonists have been shown to be efficacious in migraine pain. Thus, such persistent neuroadaptive changes may be relevant to the processes that promote MOH.

Multidisciplinary approach to obesity.

UNLABELLED: Obesity, associated with morbidity and mortality, is a complex disorder, characterised by an increase in fat mass (FM). Most authors agree in considering essential an integrated treatment made up of nutritional intervention, physical reconditioning programme and cognitive-behavioural psychotherapy. However, the feasibility is problematic and data in literature confirming the validity of this approach are poor. AIM: To verify the efficacy of a multidimensional approach (Nutritional Psycho-Physical Reconditioning - NPPR) in obesity treatment. METHODS: All patients admitted from June 2002 to June 2004 (464 subjects) ranged from 18 to 65 years old, with a body mass index (BMI) >30 kg/m2 were included in the programme. After the nutritional status evaluation a standard dietetic treatment (group N) or an integrated and multidisciplinary obesity treatment (group NPPR) was proposed. RESULTS: In group NPPR treatment duration was significantly higher (142.6+/-26 vs 48.6+/-55 days - p=0.000), while the drop-out amount was definitely lower (5.5 vs 54.4%; p=0.000). Weight loss compared to the initial weight and the difference between initial and final FM resulted significantly higher in group NNPR. Subjects in NPPR obtained a higher increase in the distance covered in a 6-minute walk test (59.9+/-19 vs 40.5+/-17 m; p=0.04) and in muscular strength. State and trait anxiety, mood and quality of life scores improved in NPPR subjects while remained substantially stable in group N. CONCLUSIONS: An integrated approach to obesity is the way to be pursued in order to obtain important and at least short-term results.

Characteristics of Enterobacter cloacae prosthetic joint infections.

OBJECTIVES: Enterobacter cloacae prosthetic joint infections (PJI) are rare and poorly documented. PATIENTS AND METHODS: We conducted a retrospective and monocentric study in an orthopedic unit supporting complex bone and joint infections. Between 2012 and 2016 we collected background, clinical, biological, and microbiological data from 20 patients presenting with prosthetic joint infection and positive for E. cloacae, as well as data on their surgical and medical treatment and outcome. RESULTS: Infections were localized in the hip (n=14), knee (n=5), or ankle (n=1). The median time between arthroplasty and septic revision was three years. Fourteen patients (70%) had undergone at least two surgeries due to previous prosthetic joint infections. The median time between the last surgery and the revision for E. cloacae infection was 31 days. Eleven patients (55%) were infected with ESBL-producing strains. The most frequently used antibiotics were carbapenems (n=9), cefepime (n=7), quinolones (n=7), and fosfomycin (n=4). The infection was cured in 15 patients (78.9%) after a 24-month follow-up. Five patients had a recurrent infection with another microorganism and four patients had a relapse of E. cloacae infection. The global success rate was 52.7% (58.3% for DAIR and 75% for DAIR+ciprofloxacin). CONCLUSION: Prosthetic joint infections due to E. cloacae usually occur early after the last prosthetic surgery, typically in patients with complex surgical and medical histories. The success rate seems to be increased when DAIR is associated with ciprofloxacin.

No Correlation between Blood Benzene Levels and Luteinizing Hormone Plasma Values in Outdoor Workers.

OBJECTIVE: The purpose of the study is to evaluate whether low-dose exposure to benzene, an environmental pollutant to which male and female traffic policemen are daily exposed to could cause alterations in plasma luteinizing hormone (LH) levels. METHODS: From an initial sample of 1594 workers, we only selected 95 workers of whom study we knew the values of late-shift benzene and LH hormone. All subjects underwent biological monitoring (final blood benzene evaluation) and luteinizing hormone dosing. Excluding subjects with the main confounding factors, the final sample included 76 workers. The normal distribution of the variables was evaluated using the Kolmogorov - Smirnov test, followed by the logarithmic transformation of the LH and benzene values. The comparison among means was performed by using the t-test for the independent samples. The ANOVA test was performed for variables with more than 2 modes (ages and seniority) and Pearson correlation index between variables in the total sample and after subdivision as to sex, job, sports activity and smoking. The results were considered significant when p values were less than 0.05. RESULTS/CONCLUSION: The study did not show a correlation between benzene levels and LH plasma levels in outdoor workers.

Molecular genetics of congenital hypothyroidism.

Congenital thyroid gland defects - resulting in reduced production of the hormones triiodothyronine (T3) and thyroxine (T4) - can be a consequence of either reduced or absent thyroid tissue (thyroid dysgenesis) or, less frequently, of impairment in the biochemical mechanisms responsible for hormone biosynthesis (thyroid dyshormonogenesis). Recent studies have revealed how mutations in the genes encoding either transcription factors or the thyroid stimulating hormone receptor cause, in humans or in mouse models, thyroid dysgenesis. This demonstrates, for the first time, the heritability of this condition. New genes responsible for thyroid dyshormonogenesis have also been discovered.

Characterization of spore forming Bacilli isolated from the human gastrointestinal tract.

AIMS: To isolate and characterize spore-former bacteria able to colonize the human gastrointestinal tract (GIT). METHODS AND RESULTS: A total of 25 spore-formers was isolated from faeces and ileal biopsies of healthy human volunteers and identified at the species level. Physiological analysis was performed to evaluate the ability of the various isolates to form biofilms, to swarm, to produce surfactants and molecules that have antimicrobial activity against selected pathogens. To assess the potential probiotic activity of the isolates, we tested the resistance of cells and spores to simulated gastric conditions, the ability to grow and sporulate in anaerobic conditions and the presence of toxin-encoding genes in their genome. CONCLUSIONS: Spore-formers belonging to various bacterial species have been isolated from the gut of healthy human volunteers. These strains appear to be well adapted to the intestinal environment and we propose them as potential probiotic strains for human use and as oral vaccine vehicles. SIGNIFICANCE AND IMPACT OF THE STUDY: To our knowledge this is the first detailed characterization of spore-forming Bacilli from the human GIT. Our data suggest that the isolated species do not transit, but rather colonize this specific habitat and propose them as probiotic strains for human use.

[Interest of admission blood sampling for the detection of somatic comorbidity in hospitalized psychiatric patients]. / Intérêt du bilan biologique d'entrée dans le dépistage de comorbidités chez les patients hospitalisés en psychiatrie.

INTRODUCTION: Elevated prevalence of somatic disorders among psychiatric patients is well known and studied since latest years. According to several studies, all-cause death risk is three to fivefold to that in the general population, and a somatic comorbidity was found in 30 to 60% of patients hospitalized in a psychiatric hospital, but was unknown in 50% of cases. OBJECTIVE: Our aim was to evaluate the interest of admission blood sampling analyses for the detection of somatic comorbidity, such as impaired glucose tolerance, diabetes mellitus, lipid abnormalities or infectious diseases among hospitalized psychiatric patients. DESIGN: During three months, laboratory tests (blood cell count, glucose, total cholesterol, HDL-cholesterol, LDL-cholesterol, triglycerides, sodium, potassium, chlorine, urea, creatinine, alanine aminotransferase, aspartate aminotransferase, gamma glutamyltransferase, alkaline phosphatase, and TSH) were determined in admission blood samples from 366 patients of two psychiatric hospitals. Then, according to the blood results, other biological tests (iron, ferritin, etc.) were made. RESULTS: For 194 of the 366 blood samples included (53%), at least one biological abnormality was detected. Moreover, variations in haematological variables, glucose and lipid concentrations were the most frequent. We found that 45 (10.6%) of the patients had impaired glucose tolerance (glycaemia > or =1.10 g/l), 21 (5.7%) had glycaemia > or =1.26 g/l, and 76 (23%) had dyslipidemia (HDL-cholesterol < or =0.40 g/l, LDL-cholesterol > or =1.60 g/l, or triglycerides > or =1.50 g/l). None of them had used glucose or cholesterol lowering drugs before the blood sampling. Furthermore, low haemoglobin concentrations were detected in 34 patients (9.3%) and high white cell counts (above 12 g/l) in 26 patients (7.1%). CONCLUSION: Despite methodological limits, these results showed the frequency of somatic comorbidity in patients hospitalized in psychiatric hospitals. Thus, admission blood sampling would be likely to improve the detection of somatic disorders, such as diabetes mellitus, dyslipidemia, or infectious diseases.
