Background/Objectives: Women of reproductive age are reported to be the largest population that practises geophagia. The short-term and long-term health related conditions originating from the practise of geophagia are often not understood by geophagic women of reproductive age. This study has explored the health-related experiences of geophagia among women of reproductive age of Tshwane District, Gauteng Province. Methods: This was a qualitative study design following inductive thematic content analysis. In-depth interviews and focus group discussions were used to collect data using an interview guide and audio record. Data collection took place in 2023. Results: Mental health disorders, pregnancy complications, appendicitis, cancers, breathing complications, fatigue, premature deaths, worms, piles, and nutrients deficiencies were reported as some of the health-related challenges and diseases experienced by women of reproductive age of Tshwane District, Gauteng Province resulting from the practise of geophagia. Conclusions: The practise of geophagia was associated with various negative health outcomes. The reproductive health statuses of women of reproductive age were negatively impacted by the practise of geophagia affecting maternal and childhood mortalities and morbidities.

Partial separation of a peripheral population may lead to its divergence and, potentially, speciation due to genetic drift followed by selection and geographic isolation. This process may cause taxonomic uncertainty because reproductive isolation in allopatry cannot be verified directly. The two Nearctic allopatric species of magpies (Aves, Corvidae: Pica) serve as a good example of these problems. The Black-billed magpie Pica hudsonia is widely distributed in North America, whereas the Yellow-billed Magpie Pica nuttalli is endemic to a restricted range in California. Their relationships with Palearctic species have been little studied. We obtained complete mitochondrial genomes of both Nearctic magpie species, along with the Eurasian Magpie (Pica pica) and the Oriental Magpie (Pica serica), 20 mitogenomes in total. Phylogenetic analysis reveals a basal position of P. serica , and P. pica as a sister clade to the two Nearctic species. P. hudsonia and P. nuttalli form reciprocal monophyletic subclades, showing recent divergence between and within them. Our data show that the Nearctic magpie lineage diverged from the common ancestor with P. pica , with a single migration wave via the Beringia. Within the Nearctic, we hypothesize a peripatric mode of speciation among Pica taxa due to the divergence and separation of the small marginal population in California below the Sierra-Nevada mountains. Diversifying amino acid substitutions in ND4-ND5-ND6 genes along the branch leading to the New World clade may indicate selection for heat-tolerance. Considering the clear phenotypic differences between P. hudsonia and P. nuttalli , our data, showing their reciprocal monophylies and genetic distinctness, is consistent with the two-species taxonomy.

Congenital lead toxicity is rare. Lead freely crosses the placenta, therefore, placing the developing fetus at a higher risk for lead toxicity. This can lead to adverse consequences, such as spontaneous abortion, low birth weight, low IQ, and neurodevelopmental impairment. We present a rare case of siblings born to a mother with pica behaviors. Her venous lead level was 42 μg/dL at the time of disclosure. The repeat venous level at delivery 2 weeks later was 61 μg/dL. The infant's venous level shortly after birth was 89 μg/dL. The neonate was transferred to the NICU, where he received 9 doses of intramuscular dimercaprol and 5 days of intravenous Ca2Na2EDTA. Seventy-two hours after completing chelation, the blood lead level rebounded to 46 μg/dL. A 19-day course of dimercaptosuccinic acid was then initiated. As of 12 months of age, he has not required additional chelation. Shortly after, the mother conceived another child, who was born prematurely at 29 weeks. Twelve days before delivery, the mother's lead level was 30 ug/dL. The infant's lead level was 32 ug/dL at the time of delivery. The infant's lead trended down without requiring chelation. Both children have since demonstrated developmental delays and have needed early intervention services. [ABSTRACT FROM AUTHOR]

Objectives: Previous analyses of New York City (NYC) health department's lead registry indicated that, among children with lead poisoning, an increased prevalence of sickle cell disease (SCD) exists. However, SCD is not considered a risk factor for lead poisoning. We assessed the association between SCD and childhood lead poisoning to determine if specific lead poisoning prevention efforts are needed for children with SCD. Methods: We analyzed NYC's lead registry data for children with venous blood lead levels (BLLs) ≥15 mcg/dL during 2005 to 2019. t tests and χ² tests were performed to compare demographic characteristics, BLLs, and lead exposure risks in non-Hispanic Black children with and without SCD. A t test was used to compare observed SCD prevalence among Black children with BLLs ≥15 mcg/dL with an estimated 0.43% SCD prevalence among Black NYC children. Results: Among 1728 Black children with BLLs ≥15 mcg/dL identified, 37 (2.14%) had SCD. When comparing children with and without SCD, both mean age at peak BLL (62.8 versus 42.7 months; P = .003) and peak BLL (42.59 versus 23.06 mcg/dL; P = .008) were higher for children with SCD. Among risk factors for lead exposure, children with SCD had higher prevalence of pica. Observed SCD prevalence was 1.71% higher than estimated SCD prevalence among Black NYC children (P < .001). Conclusions: We found a potential association between SCD and childhood lead poisoning. Pica emerged as a potentially important risk factor. Our findings might have implications for lead poisoning prevention guidelines for children with SCD. [ABSTRACT FROM AUTHOR]

Pica is a life-threatening behavior that is relatively common among individuals with intellectual and developmental disabilities. Pica can be conceptualized as a response chain in which the pica item acts as a discriminative stimulus for the next response (i.e. picking up the pica item), which itself acts as a discriminative stimulus for the final response (i.e. consumption). Interventions that disrupt this response chain and alter the discriminative properties of the pica stimulus may be clinically indicated. Preliminary research supports response-interruption and redirection (RIRD) with differential reinforcement of alternative behavior (DRA) as an effective intervention for pica. We evaluated this procedure in an inpatient unit with a young boy with who engaged in pica. Our outcomes provide additional support for DRA with RIRD as an effective pica treatment.

Haemolytic Uraemic Syndrome (HUS) is a rare medical condition characterised by microangiopathic haemolytic anaemia, thrombocytopenia, and acute kidney injury. Neurological complications are documented but rarely involve the cerebellum. We present a unique case of a 23-month-old male with HUS triggered by Escherichia coli-O157 (E.coli-O157) infection leading to an isolated cerebellar stroke. The patient initially presented with fever, bloody stools, and seizures. Confirmation of E.coli-O157 infection was obtained, and MRI revealed an isolated cerebellar stroke. Treatment included supportive care, anticoagulation for a right atrial thrombus, with gradual improvement observed. This case highlights the unusual occurrence of isolated cerebellar stroke in HUS patients, emphasising the importance of promptly recognizing manifestations of the central nervous system and the necessity for a multidisciplinary approach. Finally, a comprehensive literature review was conducted to identify cases of HUS patients with cerebellar involvement. [ABSTRACT FROM AUTHOR]

Hyaena faeces and mineral licks represent highly concentrated nutrient resources for leopard tortoises (Stigmochelys pardalis) living in nutrient‐poor environments. Here, we provide direct evidence for the consumption of hyaena faeces and artificial mineral licks by leopard tortoises in the Kalahari Desert. Tortoises aggregated at hyaena latrines and lick sites during the wet season between 10 AM and 6 PM in groups of 1–5 individuals. Where both salt and mineral licks were available, tortoises displayed a preference for salt. We suggest that calcium, phosphorus and sodium deficits are likely driving coprophagy and geophagy behaviours by tortoises in the Kalahari. [ABSTRACT FROM AUTHOR]

An 8-year-old, female, spayed Kelpie cross presented with hyporexia, pica, vomiting, collapse and seizures. It was diagnosed with eunatraemic, eukalaemic hypoadrenocorticism, immune-mediated anaemia and immune-mediated thrombocytopenia, possibly representing an example of multiple autoimmune syndrome type 3. All abnormalities resolved and the patient was alive nearly 3 years later, maintained on physiological doses of prednisolone. This case serves as a reminder of the variable presentations of eunatraemic, eukalaemic hypoadrenocorticism and the potential for concurrent immune-mediated disease. [ABSTRACT FROM AUTHOR]

Background and Objectives: Typically, the vertebral arteries (VAs) enter the posterior fossa through dural rings and further unite, forming the basilar artery. The posterior inferior cerebellar artery (PICA) is usually a branch of the V4 segment of the VA (intradural origin). It may also leave the V3 suboccipital segment of the VA (extradural origin). The transdural origin of the PICA within the VA's dural ring has been consistently overlooked. A study was designed to determine the topographical patterns of the PICA's origin. Materials and Methods: Determinations were performed in a retrospective sample of 225 computed tomography angiograms. Four types of PICA origin were documented: type 0, absent PICA; type 1, the extradural origin of the PICA from the V3 segment of the VA; type 2, the transdural origin of the PICA within the dural ring; and type 3, the intradural origin of the PICA from the V4 segment of the VA. The bilateral symmetry of types was also investigated. Results: Out of 450 VAs, type 0 (absent PICA) was found in 36%, type 1 (extradural) in 0.44%, type 2 (transdural) in 5.56%, and typical type 3 in just 58%. In types 1 and 2, the PICA entered the posterior fossa through the dural ring and the marginal sinus. In the overall group (N = 225), the type combinations 1_1, 1_2 and 1_3 were not found. Bilaterally absent PICAs occurred in 18.67%. The bilateral combinations 0_1/0_2/0_3/2_2/2_3/3_3 were found, respectively, in 0.89%/3.11%/30.67%/1.78%/4.44%/40.44%. Four of the seventy-eight PICAs opposite to an absent one, three intradural and one transdural, were true bihemispheric PICAs. Conclusions: The PICAs with extradural or transdural origins are facultative contents of the dural ring and are at risk during neurosurgical approaches in the foramen magnum. Rare bihemispheric PICAs could originate either intradurally or within the dural ring. [ABSTRACT FROM AUTHOR]

Key Clinical Message: After ingestion rubber gloves harden and can produce dangerous complications. Therefore the choice of treatment is of utmost importance. Aside from a surgical approach, endoscopy should also be considered as a treatment option on a case‐to‐case basis or if not applicable as a useful diagnostic tool. [ABSTRACT FROM AUTHOR]

Posterior inferior cerebellar artery (PICA) aneurysms are uncommon and are typically found at the origin or proximal segments of the vessel. Giant aneurysms are uncommon and present unique treatment challenges. Giant distal PICA aneurysms are exceedingly rare and have traditionally been managed via open surgical approaches. A total of 207 studies were assessed, identifying 26 cases of giant distal PICA aneurysms from 26 separate publications. One additional case is described followed by a review of presentation, anatomical characteristics, treatment and outcome. Presentation was due to local mass effect in 19 (70%), hydrocephalus in 4 (15%) and acute haemorrhage in 5 (19%). All reported cases were partially (86%) or completely (14%) thrombosed. The telovelotonsillar segment was involved in 18/24 (75%) cases. Two cases (7%) were associated with an arteriovenous malformation. Twenty-two (81%) were managed surgically and 5 (19%) managed endovascularly. Outcome was good in 22 (85%) and poor in one (4%). Giant distal PICA aneurysms can be managed effectively through a variety of open surgical and endovascular techniques. [ABSTRACT FROM AUTHOR]

Several places were discovered in the mountains of the Kodar Ridge in Transbaikalia that are regularly visited by snow sheep (Ovis nivicola) for the purpose of consuming coal (Chepa Formation, Jurassic). It was registered by trap cameras that an adult ram eats from tens to hundreds of grams of coal gruss and dust at one time. The "eatable" coals were studied comprehensively, including their geochemistry. The content and balance of mobile forms of trace elements, including rare earth elements (REEs), were determined. It has been established that the sum of REEs in coal varies from 0.19 to 0.27 kg/t, which is 3.5–4 times higher than the clarke value. Elements of the light subgroup (LREEs) predominate in the REE composition. Monazite, xenotime, and rhabdophane were revealed in the consumed coals by analytical scanning electron microscopy. Acid (HCl, pH-1) extract showed that among the elements released from the coal, only a few trace elements, including LREEs, are likely to be significant to the animals. The data that we obtained from the previous landscape-geochemical studies in the areas of mass geophagy in Sikhote-Alin and Gorny Altai and on Olkhon Island (Baikal) suggest that snow sheep on the Kodar Ridge regularly consume coal due to the intention of the animals to restore a disturbed REE balance in the body.

Taking care of persons with intellectual and multiple disabilities (IMD), especially when vulnerability and medical intervention increase, can lead to the question: to what extent is there still quality of life? In the search for answers, caretakers and families are confronted with unsolvable dilemmas such as how can we identify the meaning of this life or recognise when there is suffering? How does one understand and give meaning to quality of life where fragility is present? Society, on the other hand, which rates successful living as the standard, avoids the discussion on limits to quality of life by labelling it as a medical ethical issue. It has recently been argued that the medical perspective is leading in this discussion and is the deciding factor in giving meaning to quality of life. Such statements worry IMD healthcare professionals and caregivers. This article therefore aims to offer an insight into the professional, practical and personal care experience of both authors, to explore the issue in more depth and start a nuanced dialogue without losing sight of the immense complexity of the subject. To do this, we first outline the social context in which the healthcare practice has to take place, explaining the reality of it and the difficulties faced. [ABSTRACT FROM AUTHOR]

Pica, the urge to consume items generally not considered food, such as dirt, raw starch, and ice, are particularly common among pregnant women. However, the biology of pica in pregnancy is not well understood. Therefore, this study aimed to assess how pica relates to endocrine stress and immune biomarkers in a cohort of pregnant Latina women in Southern California. Thirty‐four women completed a structured pica questionnaire. Maternal urinary cortisol and plasma cytokine levels were measured between 21 and 31 weeks' gestation. Associations between pica during pregnancy and biomarkers were assessed using linear regression models adjusting for gestational age. Twelve (35.3%) of the pregnant women reported pica (geophagy and amylophagy) during pregnancy. In multivariate models, those who engaged in pica had higher levels of cortisol (β: 0.37, 95% CI: 0.01, 0.073) and lower levels of IL‐1β (β: −0.06, 95% CI: −0.11, −0.02), IL‐8 (β: −0.30, 95% CI: −0.56, −0.05), IL‐21 (β: −0.35, 95% CI: −0.63, −0.08), and type‐1 inflammation composite (β: −0.29, 95% CI: −0.44, −0.14) than women who did not engage in pica. These results suggest that biological stress and immune response differ for women with pica compared to those without. This study suggests novel physiological covariates of pica during pregnancy. Further research is needed to better understand the mechanisms and temporality underlying the observed associations between pica and endocrine and immune biomarkers. [ABSTRACT FROM AUTHOR]

Neurovascular compression of the rostral ventrolateral medulla (RVLM) has been described as a possible cause of refractory essential hypertension. We present the case of a patient affected by episodes of severe paroxysmal hypertension, some episodes associated with vago-glossopharyngeal neuralgia. Classical secondary forms of hypertension were excluded. Imaging revealed a neurovascular conflict between the posterior inferior cerebellar artery (PICA) and the ventrolateral medulla at the level of the root entry zone of the ninth and tenth cranial nerves (CN IX-X REZ). A MVD of a conflict between the PICA and the RVLM and adjacent CN IX-X REZ was performed, resulting in reduction of the frequency and severity of the episodes. Brain MRI should be performed in cases of paroxysmal hypertension. MVD can be considered in selected patients. [ABSTRACT FROM AUTHOR]

Background: The association of an infratentorial arteriovenous malformations (AVMs) with a PICA aneurysm is very rare and the presence of associated aneurysms was an independent predictive factor of poor outcome at follow-up for posterior fossa AVMs (pfAVMs). We report the case of a 57-year-old female patient admitted to our institution with a challenging management of a pfAVM associated with multiple flow-related aneurysms of the PICA. Case presentation: A 57-year-old patient with no medical past history was admitted to our emergency department with a sudden onset headache and severe neck stiffness. A cerebral CT Scan showed a cerebellar hematoma. Digital subtraction angiography demonstrates a right paramedian supero-posterior infratentorial AVM located at the posterosuperior part of the right cerebellar hemisphere with a small compact nidus supplied by branches of the right PICA and the right superior cerebellar artery. Venous drainage being toward the torcular. The AVM is associated with 3 flow-related aneurysms. We opted for surgical treatment of the 2 high-flow aneurysms on the distal branch of the right PICA. Patient was then sent for radiosurgery for the AVM. We opted for observation of the left small aneurysm. Conclusion: Microsurgery for PICA aneurysms is particularly well suited because exposure through a far-lateral craniotomy is excellent. Endovascular embolization can be used to occlude the aneurysm as well as treat the AVM at the same time in certain circumstances. Clipping or coiling the aneurysm should be discussed in a multidisciplinary meeting. [ABSTRACT FROM AUTHOR]

Mineral licks are key ecological components of the Amazon rainforest, providing critical dietary functions for herbivorous and frugivorous mammals and birds, which help maintain the structure and function of the forest itself through seed and nutrient dispersal. One of the most frequent visitors of interior forest mineral licks in the Amazon is the red brocket deer (Mazama americana), a large‐bodied ruminant frugivore and seed predator. While several hypotheses for the drivers of geophagy exist, including mineral supplementation, toxin adsorption, and habitat selection, robust data on geophagy for the red brocket deer for large numbers of mineral licks is nonexistent. We used soil data from 83 mineral licks in conjunction with camera trap data from 52 of those mineral licks and a mixed‐effects modeling approach to test the three proposed hypotheses of geophagy for the red brocket deer. We found that consumed soils at mineral licks had elevated concentrations of almost all major and minor biologically active minerals measured, including Ca, Na, Mg, K, Cu, Zn, and Mn. Model results suggest that all three hypotheses hold true to some extent for the red brocket deer, with the greatest support for the mineral supplementation hypothesis, in particular with respect to Mg, Ca, Na, Cu, and Zn. This study provides critical information on the feeding ecology of the red brocket deer in the wild, and the first robust analysis of geophagy of an Amazonian mammal involving a large sample size of interior forest mineral licks.

Objective: The present study examined prevalence and correlates of pica behaviors during childhood using data from the Avon Longitudinal Study of Parents and Children (ALSPAC) study. Method: Data on 10,109 caregivers from the ALSPAC study who reported pica behavior at 36, 54, 65, 77, and 115 months on their child were included. Autism was obtained through clinical and education records, while DD was derived from the Denver Developmental Screening Test. Results: A total of 312 parents (3.08%) reported pica behaviors in their child. Of these, 19.55% reported pica at least at two waves (n = 61). Pica was most common at 36 months (N = 226; 2.29%) and decreased as children aged. A significant association was found between pica and autism at all five waves (p <.001). There was a significant relationship between pica and DD, with individuals with DD more likely to experience pica than those without DD at 36 (p =.01), and 54 (p <.001), 65 (p =.04), 77 (p <.001), and 115 months (p =.006). Exploratory analyses examined pica behaviors with broader eating difficulties and child body mass index. Discussion: This study enhances understanding of childhood pica behaviors, addressing a significant gap in knowledge. Pica occurrence in the general population is poorly understood due to few epidemiological studies. Findings from the present study indicate pica is an uncommon behavior in childhood; however, children with DD or autism may benefit from pica screening and diagnosis between ages 36 and 115 months. Children who exhibit undereating, overeating, and food fussiness may also engage in pica behaviors. [ABSTRACT FROM AUTHOR]

Introduction: Anemia is a significant public health concern, primarily affecting young children, pregnant and postpartum women, and menstruating adolescent girls and women. This study aimed to evaluate the prevalence of anemia and associated factors in women of reproductive age visiting a tertiary care hospital in Karachi, Pakistan. Objective: The primary objective was to determine the prevalence of anemia in women of reproductive age, while the secondary objective was to investigate potential causes of anemia within this demographic group. Design: A prospective cross-sectional approach was employed, adhering to Strengthening the Reporting of Observational Studies in Epidemiology guidelines. A questionnaire-based method was used to assess anemia, and data were collected from women aged 14 to 40 years. Method: The study was conducted at the Jinnah Postgraduate Medical Center from January to May 2023. The study was approved by the Institutional Review Board of Jinnah Sindh Medical University (Institutional Review Board reference number JSMU/IRB/2023/699). A sample of 397 women was included, and various demographic and lifestyle factors were assessed. Results: In this study of 397 participants, 71.5% were found to have anemia, primarily microcytic anemia (48.2%). Anemia prevalence was highest among the 14–18 years age group (80.7%) and those from lower socioeconomic backgrounds (73.6%). Factors such as frequent tea consumption, irregular mealtimes, and pica consumption were associated with higher anemia rates. Pregnant women and those with more children were at a heightened risk of anemia. Conclusion: The study reveals a notable prevalence of anemia among women of reproductive age with a surprising emphasis on younger individuals and lower socioeconomic groups. Dietary habits, lifestyle choices, and pregnancy status play significant roles in anemia development. Targeted interventions are essential, particularly for younger women, those from disadvantaged backgrounds, and pregnant individuals, to combat anemia effectively in this region. Plain Language Summary: Anemia is a widespread health concern, especially in young children, pregnant women, and menstruating adolescent girls. This condition, characterized by low hemoglobin levels, leads to insufficient oxygen delivery to organs. Globally, nearly 30% of women of reproductive age suffer from anemia, with a higher prevalence in certain regions such as Pakistan. This study aimed to assess anemia prevalence and associated factors among women of reproductive age in Karachi, Pakistan. Of the 397 participants, 71.5% were anemic. Microcytic anemia was more prevalent than macrocytic anemia. Various factors contributed to anemia, including age (highest prevalence in 14 to 18 years), lower socioeconomic status, irregular meal times, and frequent tea consumption. Surprisingly, individuals who consumed iron supplements exhibited a higher prevalence of anemia. Factors contributing to higher rates of anemia included frequent tea consumption, irregular mealtimes, and the consumption of non-nutritive substances (pica). Pregnant women and those with more children were identified as having an increased risk of anemia. In addition, women with hectic schedules were more prone to anemia. These results highlight the importance of lifestyle choices, dietary habits, and pregnancy status in the development of anemia. The study underscores the need for targeted interventions to address anemia effectively, with a particular focus on younger women, individuals from disadvantaged backgrounds, and pregnant women. By understanding the specific factors contributing to anemia in this population, public health strategies can be tailored to address the unique needs of these groups, ultimately improving the overall health outcomes for women of reproductive age in the region.

Introduction: Pica and avoidant/restrictive food intake disorder are two of the three new eating and feeding disorders introduced in the DSM-5, this inclusion has drawn attention to the immediate need for research into their prevalence, diagnostic assessment, underlying risk factors and optimal treatment. There are very few studies available that explored the predictors or causes of these eating disorders specifically in Pakistani context. Objectives: The objectives of the current study include (a) to estimate the presence of pica and avoidant/restrictive food intake disorder symptomology among young adults in Pakistan, (b) to examine the relationship between dimensions of impulsivity, stress and presence of pica and avoidant/restrictive food intake disorder, (c) to explore the mediation role of stress. Methods: The sample consisted of 660 young adults with age range 18–25 years, recruited through convenient sampling. The respondents were provided with a questionnaire comprising of an informed consent, a demographic information sheet and self-report measures including PARDI-AR-Q to assess symptomology of pica and avoidant/restrictive food intake disorder, UPPS-P Impulsive Behaviour Scale to assess dimensions of impulsivity and Perceived Stress Scale to measure perceived stress. Results: The findings show that 28 participants (4.2%) reported Pica symptomology, of which eleven participants indicated that they currently consume more than one non-food item. 19 respondents (2.8%) reported avoidant/restrictive food intake disorder symptomology. 13 respondents reported varying degrees of all three symptom clusters namely sensory based food avoidance, lack of interest in food, and fear of negative consequences of eating. Additionally, each of the dimensions of impulsivity was found to be positively correlated to the presence of pica and avoidant/restrictive food intake disorder. Perceived stress was identified as a mediating factor between each of the dimensions of impulsivity and presence of pica and avoidant/restrictive food intake disorder. Conclusion: Although current study focused on a particular age range, it has drawn attention to the necessity of screening and investigating other strata of Pakistani population for pica and avoidant/restrictive food intake disorder. The clinical utility of the present research resided in the identification of factors associated with pica and avoidant/restrictive food intake disorder, an information which can be used to tailor psychological interventions, modify existing ones, and inform the future research on evidence-based treatment. Plain English Summary: The study explored pica and avoidant/restrictive food intake disorder in young adults in Pakistan. It found a presence of these disorders and identified connections with impulsivity and stress. These disorders, characterized by unusual eating behaviors and food avoidance, showed links with impulsivity dimensions and stress levels. Importantly, stress seemed to play a role between impulsivity and these disorders. This study emphasizes the need for broader research across different age groups in Pakistan to understand these disorders better. The study suggests that these eating disorders aren't confined to specific demographics, supporting the DSM-5 decision to lift age limits. In essence, this research opens doors for understanding and addressing pica and avoidant/restrictive food intake disorder in diverse populations, fostering a more comprehensive approach to mental health in the context of eating behaviors.

We evaluated the composition of soil involved in antelope jackrabbit (Lepus alleni) geophagy as a potential source of micronutrient supplementation. We identified evidence of soil digging and ingestion by antelope jackrabbits at sites with the assistance of motion-sensing cameras. Fifteen soil samples from sites with evidence of soil ingestion and 15 control samples from noningested sites were collected and analyzed for water content, iron, potassium, calcium, and sodium. We found more calcium and sodium in areas where soils were ingested, whereas potassium, water, and iron content did not differ. In conclusion, the evidence may suggest that antelope jackrabbits ingested soil to uptake necessary nutrients such as sodium and calcium. [ABSTRACT FROM AUTHOR]

Background: Artisanal and small-scale gold mining (ASGM) areas potentially pose increased exposure to arsenic and mercury through community contamination, occupations at gold mines, and/or geophagy when soil is locally sourced. This study examined the effects of geophagy, a deliberate soil eating practice, along with community and occupational exposures in ASGM areas on urinary arsenic and blood mercury levels among pregnant women in the Mining and Health Longitudinal Cohort in northwestern Tanzania. Methods: Data on maternal arsenic and mercury levels were captured for 1056 pregnant women using an unprovoked morning urine samples and dried blood spots respectively. We used a step-wise generalized linear regression model to retain the most relevant covariates for the model. A generalized linear regression model with identity link function was used to predict the effect of geophagy practices on arsenic and mercury levels separately. The model was adjusted using sociodemographic correlates, including maternal age, education level, whether respondents lived in mining or non-mining area, years of residence, marital status, maternal occupation, individual partner's education, and occupational, and socioeconomic status. Results: In the adjusted regression model, eating soil during pregnancy increased arsenic concentration by almost 23% (β = 1.229, 95% CI: 1.094, 1.38, p < 0.001) and living in mining areas had a 21.2% (β = 1.212; 95% CI: 1.039,1.414, p = 0.014) increased risk. Geophagy significantly increased mercury levels by 13.3% (β = 1.133, 95% CI: 1.022, 1.257, p = 0.018). Living in areas with ASGM activities was associated with a 142% (β = 2.422, 95% CI: 2.111, 2.776, p < 0.0001) increase in blood mercury. Conclusion: Geophagy practices increased urinary arsenic and blood mercury levels in pregnant women, which was especially true for arsenic when living in areas with ASGM activities. Working in mining = increased risk for blood mercury levels. Community-based environmental health policies should address reductions in occupational and community exposures, along with strategic geophagy reduction interventions. [ABSTRACT FROM AUTHOR]

Anemia in pregnancy represents a major global health problem, and progress is insufficient to meet the World Health Assembly's global nutrition target of halving anemia prevalence by 2030. We assessed the prevalence and factors associated with anemia among pregnant women in northern Sudan. This community-based cross-sectional study was conducted at Almatamah, River Nile State, Sudan. Sociodemographic and obstetric data were collected using a questionnaire. Hemoglobin (Hb) was measured using an automated hematology analyzer. Multivariate and simple linear regression analyses were performed. A total of 586 pregnant women were enrolled. Their median (interquartile range, IQR) age was 25 (21–30) years. The median (IQR) of body mass index (BMI) was 26.67 (24.34–30.04) kg/m2. The median (IQR) for Hb was 11.0 (10.0–11.9) g/dL. Of the 586 women, 271 (46.2%) had anemia (Hb: <11 gm/dL). In multivariate analysis, increasing BMI and obesity were significantly associated with decreased odds ratios (ORs) of anemia, while pica was associated with increased ORs of anemia. In conclusion, anemia in pregnant women is a major public health problem, as approximately half of pregnant women in northern Sudan have anemia. Increasing BMI and obesity were associated with a lower risk for anemia. More efforts are needed to improve the maternal nutritional status for good pregnancy outcomes. [ABSTRACT FROM AUTHOR]

Pabellón de Pica, Tarapaca, Chile, is a former guano mine exploited in the late 19th and early 20th centuries. Guano is in a direct contact with Cu sulfide mineralization leading to the formation of minerals with a highly unusual chemical composition, especially Cu‐organic complexes and nitrogen‐bearing phases. In this work, we report results of the Raman spectroscopic investigation of several unique Cu‐bearing minerals that are the result of supergene processes at the Pabellón da Pica site. We focus on several minerals with new and interesting structure types which were described from this locality for the first time, namely, antipinite (K–Na–Cu oxalate), ammineite (Cu ammine complex), chanabayaite (Cu ammine triazolate complex), and joanneumite (Cu isocyanurate). The Raman spectra contain specific bands attributed to the characteristic vibrations of the molecular groups present in the minerals (oxalate, ammine, triazolate, and isocyanurate groups) and vibrations within Cu‐centered polyhedra. A comparison was made with the vibrational spectra of related minerals and synthetic phases, which revealed substantial proliferation and shifting of numerous bands, which is in agreement with the complex composition of the investigated minerals.

The purpose of this study was to investigate the outcome of microvascular decompression (MVD) in patients with hemifacial spasm (HFS) who have no definite radiological neurovascular compression (NVC). Sixteen HFS patients without radiological NVC on preoperative MRI underwent MVD surgery. The symptoms were left-sided in fourteen (87.5%) and right-sided in two patients (12.5%). Intraoperatively, the most common vessel compressing the facial nerve was the AICA (8, 44.4%), followed by arterioles (5, 27.8%), veins (4, 22.2%), and the PICA (1, 5.6%). The most common compression site was the cisternal portion (13, 76.5%) of the facial nerve, followed by the REZ (4, 23.5%). One patient (6.3%) was found to have multiple NVC sites. Arachnoid type (7, 50%) was the most common compressive pattern, followed by perforator type (4, 28.6%), sandwich type (2, 14.3%), and loop type (1, 7.1%). A pure venous compression was seen in two patients, while a combined venous-arterial "sandwich" compression was detected in two patients. Symptom improvement was observed in all of the patients. Only one patient experienced recurrence after improvement. Based on our experience, MVD surgery can be effective for primary HFS patients with no definite radiological NVC. MVD can be considered if the patient shows typical HFS features, although NVC is not evident on MRI. [ABSTRACT FROM AUTHOR]

The relevance of this research is based on systematic study of the causes of geophagy from the viewpoint of the rare-earth hypothesis. It follows from the original results of comprehensive geological–hydrobiogeochemical studies carried out on Olkhon Island (Lake Baikal) that the phenomenon of geophagy in wild and domestic ungulates is due to a deficiency of light rare-earth elements (LREEs) in plant foods and natural waters. This deficiency is related to a low LREE concentration in the composition of the most common metamorphic terrigenous–carbonate rocks, talus, and soils in the island. This geochemical specificity of landscapes can be the cause of LREE imbalance in the hormonal system of the body. The hormonal stress makes animals consume regularly and periodically kaolinite clays of weathering rocks enriched in the necessary elements. [ABSTRACT FROM AUTHOR]

Purpose: To demonstrate that occipital artery (OA)-p1 posterior inferior cerebellar artery (PICA) bypass can be an alternative for complex posterior circulation aneurysms. Methods: A far-lateral approach to craniotomy was performed on 20 cadaveric specimens, and the OA was obtained 'in-line.' Its length, diameter, and the number of p1/p2 and p3 segmental perforators were determined, and the relationship between the caudal loop and cerebellar tonsil position was also assessed. The distance between the PICA's origin and the cranial nerve XI (CN XI), the buffer length above the CN XI after dissection, the OA length required to complete the OA-p1/p3 PICA bypass, and the p1 and p3 segment diameters were all measured. A bypass training practical scale (TSIO) was used to evaluate the quality of the anastomosis. Results: All specimens underwent OA-p1 PICA end-to-end bypass and had favorable results for the TSIO score, 15 sides underwent OA-p3 PICA end-to-side bypass, and the other bypass protocols were less common. The buffer length above the CN XI after dissection, the distance between the PICA's origin and the CN XI, and the first perforator were all of sufficient length. The direct length of the OA needed to complete the OA-p1 PICA end-to-end bypass was significantly less than the available length and the OA-p3 PICA end-to-side bypass, with the OA matching the p1 segment diameter. The number of p1 perforators was less than that of p3, and the OA diameter was equal to that of the p1 segment. Conclusion: OA-p1 PICA end-to-end bypass is a feasible alternative in cases in which p3 segment has high caudal loops or anatomic anomalies. [ABSTRACT FROM AUTHOR]

Geophagy has been documented in different animal taxa including Aves and particularly in Passeriformes. However, no geophagic activity has been reported in the genus Turdoides of the family Leiothrichidae belonging to the passerine order. Studies reveal the behaviour of geophagy to be aiding in nutrient supplementation, toxin neutralisation, cytoprotection, gut pH stabilisation and parasite liberation. Here, we provide a record of geophagy in Jungle Babbler Turdoides striata in a peri-urban area of Berhampur city in India. Although this species, being insectivorous, was thought to be feeding on insects, nevertheless, close observations confirmed the activity to be a case of geophagy, which was followed up by nest-building, egg-laying and hatching. The soil samples from the geophagic sites (Ca = 2415 mg/kg) contained 130% more Ca than that of the non-geophagic sites (Ca = 1050 mg/kg). The biochemical requirement of calcium throughout the reproductive phase of Turdoides sp. may corroborate the soil consumption instinct, which was also extrapolated from the reproductive success observed, because the demand for calcium in birds remains high during the egg-laying time. Although the possible explanations for geophagy, reported for the first time in this species, were oriented specifically towards Ca supplement, the present findings provide impetus for furthering research in this domain.

Pica is a severe behavior disorder involving the persistent consumption of nonnutritive substances. Due to health complications and risks for fatality, designing effective behavioral treatments that are feasible for implementation by family members at home is imperative. This case report presents a parent‐conducted functional analysis and treatment evaluation of automatically maintained pica in a teenager with autism spectrum disorder. Initial treatment with a competing stimulus was effective when paired with response interruption and redirection. Although effective, this combination of treatment components required very close parental proximity and led to increases in untargeted body‐oriented pica (e.g., ingestion of skin, hair, and nails). Upon extending treatment to include the second topography of pica, both the originally targeted (object‐oriented) pica and body‐oriented pica decreased. Nonetheless, treatment effects were not sustained while fading parent proximity. The treatment was then augmented a third time with response cost. This final treatment package produced clinically significant reductions in all pica, facilitated parent proximity fading until the participant was alone, extended to their home, and maintained over a year of follow up.

From the novel results of comprehensive geological–hydrobiogeochemical studies conducted on Olkhon Island (Lake Baikal), it follows that the phenomenon of geophagy among wild and domestic ungulates on the island is caused by the deficiency of light subgroup rare earth elements (LREE) in plant food and natural waters, while not denying the possible role of other factors. This deficiency reflects the low LREE specificity of the most abundant metamorphic terrigenous carbonate rocks on the island, as well as their overlying eluvium–deluvium and soils. The resulting specificity of the landscapes may be the cause of the LREE imbalance in the nervous and hormonal systems of the body, which makes the animals regularly and periodically consume clay (kaolinite) products from weathering, enriched with the necessary nutritional elements. The identified cause of geophagy on Olkhon Island is likely to extend to a significant part of geophagy cases among animals, including humans, especially in the equatorial zone of the Earth.

Many primate species have been observed descending to the forest floor to intentionally consume soil (geophagy) at licks. The practice of geophagy is assumed to provide health benefits, such as mineral supplementation and/or gastrointestinal tract protection. We collected data on geophagy events through the use of camera traps at Tambopata National Reserve in southeastern Peru. Two geophagy sites were monitored for 42 months, during which time we observed repeated geophagy events by a group of large-headed capuchin monkeys (Sapajus apella macrocephalus). To the best of our knowledge, this is the first report of its kind for the species. Geophagy was rare, with only 13 events recorded over the study period. All but one event took place during the dry season, and 85% of events took place in the late afternoon between 1600 and 1800 hours. The monkeys were observed consuming soil both in situ and ex situ, and displayed heightened vigilance behavior during geophagy events. Although the small sample size makes it difficult to draw clear conclusions as to the drivers of this behavior, the seasonal timing of the events and the high percentage of clay in the consumed soils suggest that these events are linked to the detoxification of secondary plant compounds in the monkeys' diet.

This article discusses the case of a 42-year-old man with severe chronic schizophrenia who presented with vomiting and weight loss. The patient had a history of ingesting small objects, which were found to be causing a blockage in his stomach. The diagnosis was pica, malnutrition, and anemia, and the patient underwent surgery to remove the objects. Despite treatment, the patient continued to ingest objects and required further endoscopic removal. The article highlights the potential dangers of pica and the need for appropriate intervention based on the clinical presentation. [Extracted from the article]

Background: Pica, the craving for and purposive eating of non-food items, is a common worldwide problem, especially among children and pregnant women. There are few published data on pica among adolescents in sub-Saharan Africa, and no study has been carried- out in Sudan. This study was conducted to determine the prevalence and associated factors of symptoms of pica among adolescent schoolchildren in northern Sudan. Methods: A school‑based cross‑sectional study was conducted from July to September 2022 among adolescent students (aged 10–19 years) in four public primary and secondary schools in Almatamah locality in north Sudan. Sociodemographic information (age, sex, mother's education, mother's occupation, and father's education) was collected through a questionnaire. Weight and height were measured using a standard procedure, and the body mass index Z-score was computed using the World Health Organization's reference values. Logistic regression analysis was performed. Results: Of the 384 enrolled adolescents, 180 (46.9%) were male and 204 (53.1%) were female. Their median (interquartile range) age was 15.1 (13.1‒16.3) years. The prevalence of symptoms of pica was found to be 30.7%, accounting for 118 adolescents. The most common type of pica was geophagia (eating clay and sand; 102 adolescents, 86.4%), followed by pagophagia (eating ice; 14 adolescents, 11.8%) and flour (starch; two adolescents, 1.6%). In the logistic regression analysis, females (adjusted odds ratio = 3.52, 95% confidence interval (CI) = 2.15‒5.78) and a lower level of father's education (adjusted odds ratio = 2.05, 95% CI = 1.26‒3.34) were associated with symptoms of pica. Conclusion: In Sudan, symptoms of pica are common among adolescents, especially females. Caregivers need to assess pica in adolescents. Further research is needed to develop guidelines, medical training, and practice. Plain English summary: We conducted this study from July to September 2022 to estimate the rate of adolescents who would eat non-food items (pica) in Sudan. We gathered sociodemographic characteristics through a questionnaire. Of the 384 enrolled adolescents, 180 (46.9%) were male and 204 (53.1%) were female. We found that 118 (30.7%) adolescents would eat non-food items (pica) and that the most common type was eating clay and sand (102 adolescents, 86.4%), followed by eating ice (14 adolescents, 11.8%) and flour (starch; 2 adolescents, 1.6%). Females and those with a lower level of father's education were likely to eat non-food items. [ABSTRACT FROM AUTHOR]

Pica is an eating disorder characterized by compulsive eating of non-food items. It can present to dentists through patient medical histories, and also through causing atypical patterns of non-carious tooth surface loss. In highlighting two cases of pica presenting in general practice, we aim to raise awareness of this condition and its dental implications. CPD/Clinical Relevance: This article advises on how pica may present to a general dentist and gives advice on management. [ABSTRACT FROM AUTHOR]

Background: The parapharyngeal internal carotid artery (pICA) could be surgically exposed through the transnasal and transoral corridors. However, their potential degree of exposure has not been established sufficiently. This study aims to elucidate the maximal exposure of the pICA via the transnasal and transoral corridors. Methods: An endonasal transpterygoid nasopharyngectomy for exposure of the pICA was performed on eight cadaveric specimens (16 sides), while a transoral approach for exposure of the pICA was performed on six additional specimens (12 sides). In addition, the CT angiography of 60 consecutive patients (120 sides) was analyzed to establish the potential maximal exposure of the pICA through each corridor. Results: The hard palate becomes a restricting factor for the inferior exposure of the pICA via the transnasal approach, whereas the entire pICA segment could be adequately displayed through the transoral corridor. The maximal exposed length of the pICA for a transnasal and transoral approach was 3.08 ± 0.30 cm and 6.56 ± 0.57 cm, respectively. This difference was statistically significant (p < 0.001). Conclusion: An endonasal exposure of the pICA seems limited to its superior aspect, whereas the transoral corridor could provide adequate exposure of the entire length of pICA.

Die Bibliographia Cartographica ist seit fast 50 Jahren eine wichtige Recherchequelle der internationalen kartographischen Fachcommunity. Ursprünglich als Druckausgabe veröffentlicht und dann in eine Datenbank migriert, muss sie aktuell, funktional und erweiterbar bleiben. Aus diesem Grund wurden ihre Daten aus veralteten Datenbankstrukturen in den Verbundkatalog des GBV migriert. Der Artikel beschreibt Herausforderungen und Arbeitsschritte dieses Migrationsprojekts, in dessen Mittelpunkt das Werkzeug OpenRefine stand. Weiterhin werden alle dafür verwendeten Tools vorgestellt und das erforderliche Mapping der Daten ins PICA-Format beschrieben. The Bibliographia Cartographica has been a major search resource for specialists and professionals in the cartographic community across the globe for the last 50 years. Originally a print edition, it has been migrated to a database, which must be functional, extendable and permanently updated. The data have seen a migration from rather outdated database structures to the GBV union catalogue. The paper describes the challenges and procedures of this migration project in which OpenRefine was instrumental. We introduce tools that were used and describe the process of mapping the data in PICA format. [ABSTRACT FROM AUTHOR]

Pica is a life threating form of challenging behavior displayed by individuals with intellectual and developmental disabilities. In most cases, pica is maintained by automatic reinforcement. Common interventions for pica use some combination of response blocking, response interruption and redirection (RIRD), differential reinforcement of alternative behavior (DRA), and noncontingent reinforcement with competing stimuli. However, there is need for additional research regarding DRA procedures that emphasize skills acquisition by teaching alternative behaviors that modify the established behavioral chain of pica responses that occur in the presence of non‐edible stimuli. There is also a need to examine the generality of recent advances in competing stimulus assessment (CSA) methodologies—namely, the augmented‐CSA (A‐CSA)—to pica. Thus, the purpose of the present investigation was to systematically replicate and extend previous research for the assessment and treatment of pica in an individual with IDD. First, we conducted a functional analysis to identify environmental variables associated with pica. Next, taught Patrick a differential response (i.e., discard pica items in trash receptacle) to earn reinforcers in conjunction with a RIRD procedure. Finally, we conducted an A‐CSA for pica. Overall, low rates of pica were maintained over time with a combination of these procedures, and treatment was generalized across settings and people. [ABSTRACT FROM AUTHOR]

Ingestion of foreign bodies are common emergency situations. Pica is a form of eating disorder in adults. We report 3 cases of digestive lesions in patients with Pica in the visceral emergency department of the Yalgado Ouédraogo University Hospital. The 1st case was that of a 36-year-old female patient with a 5-year history of psychiatric disorders. She was treated for acute generalized peritonitis due to ileal perforation. The plane abdominal x-ray showed numerous non consumable intra-abdominal objects. Laparotomy was performed. The second case describes a 21-year-old female patient who was seen for fever and right iliac fossa pain. Plain abdominal x-ray revealed calcium like opacities describing the colonic framework and the small intestine compatible with geophagy, an appendectomy was performed. The 3rd patient was a 22-year-old patient who was admitted with acute generalized peritonitis. There was a 3-year history of depression. The plain abdominal x-ray showed an intra-abdominal metallic object compatible with a mechanic's flat key. Laparotomy was performed. The management of pica should be mainly preventive and educational. Surgery remains necessary in case of mechanical complications of these ingested bodies. [ABSTRACT FROM AUTHOR]

Data on the diet of Testudo hermanni and T. graeca have been published in Bulgaria for more than a century. Yet, few studies have provided more details on the feeding habits of the two species. Here, we present information about their diet in south-western Bulgaria where they coexist. The results showed that T. graeca fed exclusively on plants, whereas T. hermanni was more opportunistic and supplemented its diet with other food sources, including ants and soil particles.

South African communities, especially in rural areas, still use indigenous practices such as applying soil paste as sunscreen, building huts with soil and stones and geophagia among others. This study aimed at identifying non-agricultural uses of soil in uMgungundlovu district of KwaZulu-Natal, South Africa, while focusing on the three areas Elandskop, KwaNxamalala and Willowfontein. Information was gathered using key informant interviews and household questionnaires. Results showed that the most common soil uses were for cosmetics and as geophagia, followed by construction, with medicinal use being the least common. Cosmetic use involved using soil as sunscreen or skin cleaner. While geophagic soil was mostly consumed for enjoyment, to satisfy cravings and least of all as a nutrient supplement. Medicinal soil was mostly used to treat wounds and skin ailments such as rashes and acne. Users believed that their pre-treatment methods such as boiling, burning or baking before use were effective in reducing microbial loads and other contaminants in the soil. [ABSTRACT FROM AUTHOR]

Pica is a sustained, compulsive eating behavior of nonedible substances. Pica has been described as sequelae of psychosis due to its state of disorganization; however, temporal and causal relationship between the two has not been reported in the context of exacerbation of pica before psychosis. Various causes of pica have been identified including malnutrition, iron-deficiency anemia, zinc deficiency, intellectual disability, and obsessive and impulse control disorders. Here, we describe a case of worsening pica which preceded exacerbation of psychosis in an 18-year-old female which was managed with antipsychotics along with complete remission of psychosis and improvement in the severity of pica. The present case highlights the association between psychosis and pica. There has been a rising voice in academia to reclassify pica alongside obsessive-compulsive disorder (OCD) with no absolute consensus. In conclusion, our findings suggest that the exacerbation of pica preceded psychosis and can be construed as an indicator for an upcoming psychotic episode or as a prodromal aspect of psychosis and may be useful for early identification and initiation of treatment in cases of relapsing psychosis.

The posterior inferior cerebellar artery (PICA) has a unique anatomical complexity, which is of great clinical importance and is involved in many pathologies, such as aneurysm, ischemic stroke, neurovascular compression syndrome (NVCS), arteriovenous malformation (AVM) and brain tumour (1). PICA has a sinuous and variable trajectory, divided into 5 segments. PICA infarction usually manifests lateral bulbar syndrome and is more likely to cause mass effects. PICA frequently compresses the bulb and cranial nerves, resulting in various neurovascular compression syndromes (NVCS) (2). The ischemic stroke caused by thromboembolism in the PICA segment is accounted for more than 2% of all cases of ischemic stroke (3). Moreover, it tends to be underdiagnosed due to the symptomatology, represented usually by vertigo which mimics a possible peripheral vestibulopathy (4). [ABSTRACT FROM AUTHOR]

Zones of secondary contact provide a good opportunity to investigate the origin and dynamics of reproductive isolation between related populations. We analyzed genetic and phenotypic patterns and gene flow between two subspecies of the Eurasian magpie Pica pica s.l. which recently came into contact after presumably long periods of isolation. We describe the distribution of subspecies in a young contact zone at Argun' river basin in southern Siberia where populations occur in parapatry and an older hybrid population in eastern Mongolia. Based on genome-wide SNP data, we analyzed patterns and strength of gene flow between the subspecies. Our results indicate occasional hybridization with backcrossing and asymmetric introgression along a wide range in Transbaikalia and locally in eastern Mongolia. Males of P. p. jankowskii apparently exhibit higher dispersal ability towards the west compared to P. p. leucoptera (towards the east). The former occasionally migrates to eastern Mongolia and Transbaikalia where introgression of nuclear, but not mitochondrial DNA was evident. Bioacoustic investigations showed differences between the subspecies in speed and structure of vocalization. We discovered intermediate calls of hybrid magpies and bilingual birds alternating calls that are typical for the two taxa. Furthermore, we found dramatically decreased reproductive success in hybridogeneous populations. By complementing our results with established phylogeographic patterns of P. pica s.l. based on a mitochondrial marker sequence, and considering indications of sterility of hybrids in the contact zone, we propose to elevate the two corresponding subspecies to species level: P. pica for the western form and P. serica for the eastern form.

Background: The Pica, ARFID, and Rumination Disorder Interview (PARDI) is a structured interview that can be used to determine diagnosis, presenting characteristics, and severity across three disorders, including avoidant/restrictive food intake disorder (ARFID). The purpose of this study was to evaluate the psychometric properties of a questionnaire focused specifically on ARFID (PARDI-AR-Q), which has the potential to provide related information with less participant burden. Methods: Adolescents and adults (n = 71, ages 14–40 years) with ARFID (n = 42) and healthy control participants (HC, n = 29) completed the PARDI-AR-Q and other measures. A subset of the ARFID group (n = 27) also completed the PARDI interview. Results: An exploratory factor analysis of proposed subscale items identified three factors corresponding to the ARFID phenotypes of avoidance based on the sensory characteristics of food, lack of interest in eating or food, and concern about aversive consequences of eating. Further analyses supported the internal consistency and convergent validity of the PARDI-AR-Q subscales, and subscale ratings on the questionnaire showed large and significant correlations (all p-values < 0.001; r's ranging from 0.48 to 0.77) with the corresponding subscales on the interview. The ARFID group scored significantly higher than HC on all subscales. Furthermore, 90% of the ARFID group scored positive on the PARDI-AR-Q diagnostic algorithm while 93% of the HC scored negative. Conclusions: Though replication in larger and more diverse samples is needed, findings provide early support for the validity of the PARDI-AR-Q as a self-report measure for possible ARFID in clinical or research settings. Plain English summary: Few measures are available for detecting avoidant/restrictive food intake disorder (ARFID) in clinics or research settings. This makes it difficult for individuals with the disorder to be identified and offered appropriate care. We developed the Pica, ARFID, and Rumination Disorder Interview ARFID Questionnaire (PARDI-AR-Q), a brief self-report measure of possible ARFID, and evaluated how well it worked in the current study. In our preliminary study of 71 adolescents and adults, most individuals with ARFID (90%) scored positive on this measure, whereas most healthy control participants (93%) scored negative. Our findings provide early support for the PARDI-AR-Q as a promising new measure for detecting possible ARFID when a full clinical interview is not possible. [ABSTRACT FROM AUTHOR]

Geological and hydrobiogeochemical studies carried out in two areas of active geophagy among herbivorous animals in the area of Teletskoye Lake in the Altai Mountains suggest that consumption of lithogenic substances by animals is typical for mountain-taiga and mountain-steppe landscapes with high soluble REE contents in rocks. The high soluble REE contents were measured in the deluvial deposits of some magmatic and metamorphic rocks, as well as in the associated glacial deposits and in the derived soils and vegetation. The revealed geochemical specificity of landscapes similar to that previously established in the Sikhote-Alin becomes the cause of unbalance in the composition and concentration of REEs in the neuroimmunoendocrine system of the animal body. Being in a state of hormonal stress, animals try to compensate for this problem by consuming mineral sorbents, which, as we found out, can remove excess REEs from the body. [ABSTRACT FROM AUTHOR]

SUMMARY: Pica is a condition associated with a number of physical and mental health diagnoses. The potentially fatal consequences of pica and the links with significant physical health problems are not always recognised. Pica is like other forms of behaviour that can challenge: clinicians must seek the underlying cause and treat this first, before primarily pursuing a behavioural form of treatment. In this article, we discuss the associations, consequences, assessment and management options available for pica to guide professionals. Pica often presents in a way individual to the particular patient, so tailoring of assessment and treatment is important. [ABSTRACT FROM AUTHOR]
