Misinterpretation of common endocrine hormonal immunoassays can distort the clinical picture and lead to unnecessary medical workups. Potential assay inference is important to recognize when the clinical presentation and laboratory evaluation are inconsistent. This is demonstrated by the case of an 18-month-old girl who initially presented with ketotic hypoglycemia and was found on diagnostic fasting evaluation to have the triad of hypoglycemia, inappropriately high insulin levels, and low C-peptide levels-point-of-care glucose 43 mg/dL (2...

Small streams are essential parts of water ecosystems, such as rivers, lakes, and reservoirs, performing vital functions in the attenuation of nutrient pollution. As eutrophication becomes an increasingly severe problem in waters, it is necessary to investigate how to improve nutrient retention potential in streams. In this study, the effect of artificial manipulation was examined on transient storage and nutrient uptake in streams by setting up the stepping stone structures of flying-geese pattern (SG) and the combination mode of SG and bilaterally staggered spur dikes (SG+SD) in the channel...

OBJECTIVE: Patients with factitious disorder imposed on self (FDIS) seek medical care for deliberately falsified problems. Although a large amount of work has been published, the scientific literature lacks robust data on FDIS. The present study aimed to estimate the annual mean of in-hospital FDIS codings in France, describe the sociodemographic characteristics of subjects with FDIS, assess healthcare utilisation and medical nomadism, and describe the pathologies most frequently associated with FDIS...

INTRODUCTION: In this study, we introduce the concept of comorbidity between factitious disorder (FD), borderline personality disorder (BPD), dysthymia (DY), medically unexplained physical symptoms (MUPS) and functional neurological disorder (FND) characterising patients who may tend to exaggerate physical or psychiatric symptoms of presentation to a general or psychiatric hospital with a constellation of signs that do not receive confirmation from further clinical and instrumental assessments...

BACKGROUND: Factitious disorder imposed on self (FDIS), also known as Munchausen's syndrome, is a psychological disorder characterized by falsification of physical or psychological symptoms without an obvious external incentive. Oral presentations of FDIS are infrequently reported, and diagnosis might be challenging because affected patients often have impressive skills in fabricating symptoms and deceiving healthcare professionals. AIM: To describe the diagnostic dilemma and management challenges in a female patient who presented with tooth ache and oral ulcers...

BACKGROUND: Anastatus japonicus Ashmead, a biological control agent utilized in China to control fruit bugs and forest caterpillars, is efficiently raised on large Chinese oak silkworm (Antheraea pernyi) eggs. Here, we investigated the biological parameters of non-diapaused and diapaused A. japonicus after long-term storage within eggs of the host, A. pernyi, under laboratory conditions. RESULTS: Diapaused mature larvae of A. japonicus were much cold-tolerant than non-diapaused mature larvae, as reflected by a lower supercooling point, lower freezing point, and higher survival rate at cold temperatures...

Diabetes is the leading cause of end-stage kidney disease (ESKD), accounting for approximately 50% of patients starting dialysis. However, the management of these patients at the stage of chronic kidney disease (CKD) remains poor, with fragmented care pathways among healthcare professionals (HCPs). Diagnosis of CKD and most of its complications is based on laboratory evidence. This article provides an overview of critical laboratory evidence of CKD and their limitations, such as estimated glomerular filtration rate (eGFR), urine albumin-to-creatinine ratio (UACR), Kidney Failure Risk Equation (KFRE), and serum potassium...

The predatory mites of the Phytoseiidae family are crucial biological control agents widely utilized in biological pest management targeting phytophagous mites and insects. Key factors in these control strategies are that phytoseiids must be able to find their main target prey and to maintain high populations and efficacy. To reduce expenses and time-consuming production methods of mass rearing of phytoseiids, pollen and other factitious (i.e., non-natural/nontarget) hosts need to be present as an alternative food for predatory mite populations...

Wasps in the genus Sclerodermus are ectoparasitoids that typically attack the larvae of woodboring coleopterans. Interest in these species is increasing as they are used in programs to control longhorn beetle pests of economic importance in China and have invasive pest control potential in Europe. Wasps may be mass reared for field release, but using the target host species can be time consuming and physically demanding. There is thus a need for factitious hosts with lower production costs and that are easier to rear...

Factitious disorders represent deliberately fabricated dissimulation of physical and psychological signs and symptoms seeking medical attention by the patient. Usually, they are ignorant of conventional treatment and consistently change their version of signs and symptoms. Due to various changes in the version, they do not respond to the treatment. They describe their signs and symptoms as dissimulated, imaginative, and exasperated, involving any part of the body. Gingivitis artefacta is an unusual and dramatic presentation with self-inflicted physical injury to the gingival tissues...

The terrestrial ecosystem is the cradle of energy and material basis for human survival and development. However, there are large research deficits in accurately and finely depicting the quality of the terrestrial ecosystem (QTE) and assessing its changing triggers' contribution. Here, we summarized three major principles for selecting image sources in remote sensing data fusion. A continuous 30-m net vegetation productivity (NPP) dataset during 2000-2019 for the Guangdong-Hong Kong-Macao Greater Bay Area (GBA) was derived by using the Carnegie-Ames-Stanford approach model and pre-fused normalized difference vegetation index...

Tetrastichus howardi (Olliff) (Hymenoptera: Eulophidae) parasitizes the diamond back moth Plutella xylostella (L.) (Lepidoptera: Plutellidae), but not much is known about its potential as a biocontrol agent. A rearing protocol has been established for this parasitoid on pupae of the factitious host Tenebrio molitor (L.) (Coleoptera: Tenebrionidae), with the aim of releasing it in the field to manage several lepidopteran species. The potential population growth of a parasitoid can be measured through fertility life tables and provide supporting information for using T...

The term artifactual hypoglycemia refers to a discrepancy between plasma glucose levels and what is noted on fingerstick glucose checks. In this report, we discuss the cases of two patients with scleroderma and Raynaud's phenomenon who developed artifactual hypoglycemia while recovering from critical illness. In both cases, validation by earlobe measurements helped avoid further escalation of care and potential patient safety issues. There have been previous reports of artifactual hypoglycemia in this patient population, but the unique timing of symptom onset in these two patients provides a more nuanced understanding of the pathophysiology of this phenomenon...

BACKGROUND: There is a high prevalence of somatoform disorders and medically unexplained symptoms. When it comes to deciding whether a patient is able to work, it is essential to differentiate a somatoform disorder from a factitious disorder. The case presented demonstrates the impact on disability benefits and the subsequent psychosocial repercussions of misdiagnosing between a factitious disorder and a somatoform disorder. CASE PRESENTATION: A 42-year-old Caucasian woman worked as a 100% fiduciary accountant until the age of 32 when she was placed on medical leave due to persistent trigeminal neuralgia...

UNLABELLED: Munchausen syndrome is known as a factitious disorder imposed on the self. Factitious Cushing's syndrome (CS) is a very rare form of Munchausen syndrome, presenting with varied clinical and biochemical features, making diagnosis challenging. CASE PRESENTATION: A 40-year-old female patient who worked as a registered nurse presented with clinical features of CS but denied any exogenous corticosteroid use. The endocrine workup revealed that the patient had a high 24 h urinary-free cortisol collection before admission...

UNLABELLED: Two hospitals noted increased newborn hyperbilirubinemia coinciding with an undisclosed total serum bilirubin (TSB) assay change. Clinicians rapidly applied quality improvement methodologies to ascertain increased jaundice evaluations, readmissions, and possible safety issues. METHODS: In January 2020, 2 hospitals (A and B) transitioned to a new method of measuring TSB using a new clinical chemistry analyzer (Siemens Atellica CH), which measured TSB by vanadate oxidase assay instead of the previous diazo assay...

The spider mites Eotetranychus sexmaculatus , Eutetranychus orientalis and Oligonychus biharensisin are severe pests of rubber trees in China. The predatory mite Neoseiulus barkeri has been found to be a natural enemy of these three pests, while nothing is known about the biological performance of this phytoseiid predator against these phytophagous mites. In this study, the development, survivorship, reproduction, adult longevity, fecundity, sex ratio and population growth parameters of N. barkeri fed on these pests were evaluated in comparison to the factitious prey Tyrophagus putrescentiae in the laboratory at 25 ± 1 °C, 75 ± 5% relative humidity and a 12:12 (L:D) h photoperiod...

We present the case of a young woman with an extensive medical history that most notably includes over 60 emergency-room visits for unfounded respiratory distress that often prompted intubations. Each presentation displays elements of deceitfulness or inappropriate demands that align with factitious disorder imposed on self. Top experts in the Consultation-Liaison field provide guidance for this commonly encountered clinical case based on their experience and review of available literature. Key teaching topics include a review of risk factors for development of deceptive syndromes, distinguishing factitious disorder from malingering and conversion disorder, and the role of a consulting psychiatrist in such cases...
