Evaluation of the usefulness of insertion-null markers in critical skeletal remains.

Forensic DNA analysis in compromised skeletal remains may pose challenges due to DNA degradation, often resulting in partial or negative autosomal STRs profiles. To address this issue, alternative approaches such as mitochondrial DNA or SNPs typing may be employed; however, they are labour-intensive and costly. Insertion-null alleles (INNULs), short interspersed nuclear elements, have been suggested as a valuable tool for human identification in challenging samples due to their small amplicon size. A commercial kit including 20 INNULs markers along with amelogenin (InnoTyper® 21) has been developed. This study assesses its utility using degraded skeletal remains, comparing the results obtained (the number of detected alleles, RFU values, PHR, and the number of reportable markers) to those obtained using GlobalFiler™. Subsequently, the random match probability of the two profiles for each sample was determined using Familias version 3 to evaluate the power of discrimination of the results obtained from each kit. In every sample, InnoTyper® 21 yielded more alleles, higher RFU values, and a greater number of reportable loci. However, in most cases, both profiles were similarly informative. In conclusion, InnoTyper® 21 serves as a valuable complement to the analysis of challenging samples in cases where a poor or negative profile was obtained.

Drug-induced orthostatic hypotension: Cluster analysis of co-prescription patterns in older people in UK primary care.

PURPOSE: Over 250 medications are reported to cause orthostatic hypotension, associated with serious adverse outcomes in older adults. Studies suggest a harmful cumulative risk of orthostatic hypotension with multiple medication use. However, there is limited evidence on the potential for harm in practice, particularly which drugs is co-prescribed and may increase risk of orthostatic hypotension. METHODS: Retrospective cohort study and cluster analysis using general practice data from IQVIA Medical Research Data (IMRD) in patients aged ≥50 contributing data between 1 January 2018 and 31 December 2018. Thirteen drug groups known to be associated with orthostatic hypotension by mechanism, were analyzed and clusters generated by sex and age-band. RESULTS: A total of 602 713 individuals aged ≥50 with 283 912 (47%) men and 318 801 (53%) women were included. The most prevalent prescriptions that might contribute to orthostatic hypotension were ACE inhibitors, calcium-channel blockers, beta-blockers, selective serotonin reuptake inhibitors and uroselective alpha-blockers. We identified distinct clusters of cardiovascular system (cardiovascular system) drugs in men and women at all ages. cardiovascular system plus psychoactive drug clusters were common in women at all ages, and in men aged ≤70. cardiovascular system plus uroselective alpha-blockers were identified in men aged ≥70. CONCLUSIONS: Distinct clusters of drugs associated with orthostatic hypotension exist in practice, which change over the life course. Our findings highlight potentially harmful drug combinations that may cause cumulative risk of orthostatic hypotension in older people. This may guide clinicians about the potential of synergistic harm and to monitor for orthostatic hypotension if using combinations of cardiovascular system drugs, cardiovascular system plus psychoactive drugs and/or alpha-blockers-particularly in patients aged ≥70 or at high-risk due to comorbidity. Future research should consider quantifying the risk of drug-induced orthostatic hypotension with such drug combinations.

Understanding the association between pain and delirium in older hospital inpatients: systematic review and meta-analysis.

OBJECTIVE: Delirium and pain are common in older adults admitted to hospital. The relationship between these is unclear, but clinically important. We aimed to systematically review the association between pain (at rest, movement, pain severity) and delirium in this population. METHODS: PubMed, EMBASE, CINAHL, PsycINFO, Cochrane and Web of Science were searched (January 1982-November 2022) for Medical Subject Heading terms and synonyms ('Pain', 'Analgesic', 'Delirium'). Study eligibility: (1) validated pain measure as exposure, (2) validated delirium tool as an outcome; participant eligibility: (1) medical or surgical (planned/unplanned) inpatients, (2) admission length ≥ 48 h and (3) median cohort age over 65 years. Study quality was assessed with the Newcastle Ottawa Scale. We collected/calculated odds ratios (ORs) for categorical data and standard mean differences (SMDs) for continuous data and conducted multi-level random-intercepts meta-regression models. This review was prospectively registered with PROSPERO [18/5/2020] (CRD42020181346). RESULTS: Thirty studies were selected: 14 reported categorical data; 16 reported continuous data. Delirium prevalence ranged from 2.2 to 55%. In the multi-level analysis, pain at rest (OR 2.14; 95% confidence interval [CI] 1.39-3.30), movement (OR 1.30; 95% CI 0.66-2.56), pain categorised as 'severe' (OR 3.42; 95% CI 2.09-5.59) and increased pain severity when measured continuously (SMD 0.33; 95% CI 0.08-0.59) were associated with an increased delirium risk. There was substantial heterogeneity in both categorical (I2 = 0%-77%) and continuous analyses (I2 = 85%). CONCLUSION: An increase in pain was associated with a higher risk of developing delirium. Adequate pain management with appropriate analgesia may reduce incidence and severity of delirium.

Cultural adaptation to Bolivian Quechua and psychometric analysis of the Patient Health Questionnaire PHQ-9.

OBJECTIVE: Cultural adaptation of the Patient Health Questionnaire-PHQ-9 to Bolivian Quechua and analysis of the internal structure validity, reliability, and measurement invariance by sociodemographic variables. METHODS: The PHQ-9 was translated and back-translated (English-Quechua-English) to optimise translation. For the cultural adaptation, experts, and people from the target population (e.g., in focus groups) verified the suitability of the translated PHQ-9. For the psychometric analysis, we performed a Confirmatory Factor Analysis (CFA) to evaluate internal validity, calculated α and ω indices to assess reliability, and performed a Multiple Indicator, Multiple Cause (MIMIC) model for evaluating measurement invariance by sex, age, marital status, educational level and residence. We used standard goodness-of-fit indices to interpret both CFA results. RESULTS: The experts and focus groups improved the translated PHQ-9, making it clear and culturally equivalent. For the psychometric analysis, we included data from 397 participants, from which 73.3% were female, 33.0% were 18-30 years old, 56.7% reported primary school studies, 63.2% were single, and 62.0% resided in urban areas. In the CFA, the single-factor model showed adequate fit (Comparative Fit Index = 0.983; Tucker-Lewis Index = 0.977; Standardized Root Mean Squared Residual = 0.046; Root Mean Squared Error of Approximation = 0.069), while the reliability was optimal (α = 0.869-0.877; ω = 0.874-0.885). The invariance was confirmed across all sociodemographic variables (Change in Comparative Fit Index (delta) or Root Mean Square Error of Approximation (delta) < 0.01). CONCLUSIONS: The PHQ-9 adapted to Bolivian Quechua offers a valid, reliable and invariant unidimensional measurement across groups by sex, age, marital status, educational level and residence.

Witnessing inter-parental violence in childhood and help-seeking behaviours in violence against women in Peru.

BACKGROUND: Violence against women (VAW) severely impacts their physical and mental health. In some cultures, women can normalize certain types of violence if they were linked to home models in childhood and, eventually, do not seek for help in adulthood. We aimed to determine, in Peruvian women, (1) the association between witnessing violence in their family of origin and VAW experienced in adulthood, (2) the extent to which women who have experienced VAW seek some help, and (3) identify VAW prevalence by Peruvian region. METHODS: Cross-sectional study of secondary data obtained from the 2019 National Demographic and Family Health Survey (ENDES). The outcome was VAW (psychological, physical and sexual violence), whereas the exposure was witnessing violence in the home of origin. Help-seeking behavior was a secondary outcome, for which VAW was the exposure. Prevalence ratios (PR) were estimated to assess both associations, unadjusted and adjusted for covariates (aPR). RESULTS: Data from 14,256 women aged 15 to 49 years were analysed. 51.5% reported having experienced VAW and 43.8% witnessed violence in the home of origin during childhood. Witnessing inter-parental violence in childhood was associated with psychological violence aPR = 1.25 (95% CI: 1.17-1.33), physical aPR = 1.52 (95% CI: 1.38-1.67), and sexual aPR = 1.99 (95% CI: 1.57-2.52). Women who have experienced both types of violence (physical and sexual) were more likely to help-seeking (aPR = 1.30, 95% CI: 1.14-1.50) than women suffering only one type of violence. CONCLUSION: Women who reported having witnessed home violence in their childhood are more likely to experience Violence Against Women (VAW) by their current partner. Physical and sexual violence with a current partner was more associated with witnessing inter-parental violence in childhood, and when physical and sexual violence jointly occurred women were more help-seeking. The southern region of Peru is identified as an area of high vulnerability for women. It is crucial to promote educative and community-based programs aimed at the prevention and early recognition of VAW.

A comparison between petrous bone and tooth, femur and tibia DNA analysis from degraded skeletal remains.

Skeletal remains are the only biological material that remains after long periods; however, environmental conditions such as temperature, humidity, and pH affect DNA preservation, turning skeletal remains into a challenging sample for DNA laboratories. Sample selection is a key factor, and femur and tooth have been traditionally recommended as the best substrate of genetic material. Recently, petrous bone (cochlear area) has been suggested as a better option due to its DNA yield. This research aims to evaluate the efficiency of petrous bone compared to other cranium samples (tooth) and postcranial long bones (femur and tibia). A total amount of 88 samples were selected from 38 different individuals. The samples were extracted by using an organic extraction protocol, DNA quantification by Quantifiler Trio kit and amplified with GlobalFiler kit. Results show that petrous bone outperforms other bone remains in quantification data, yielding 15-30 times more DNA than the others. DNA profile data presented likeness between petrous bone and tooth regarding detected alleles; however, the amount of DNA extracted in petrous bones allowed us to obtain more informative DNA profiles with superior quality. In conclusion, petrous bone or teeth sampling is recommended if DNA typing is going to be performed with environmentally degraded skeletal remains.

GITAD 2020: quality assurance test through 20 years of experience.

GITAD (Grupo Iberoamericano de Trabajo en Análisis de DNA) was founded in 1998 as the first operational group of AICEF (Academia Iberoamericana de Criminalística y Estudios Forenses), formally created in 1999. The mission and the vision of GITAD are to promote the development of forensic genetics in Ibero-American countries and to achieve the maximum level of innovation and quality in each country, and with that aim, a proficiency test was developed. Since 1999, the member laboratories receive four reference samples with the objective of obtaining the genetic profile with their routine protocols, a theoretical exercise since 2003, and since 2007, it was incorporated a forensic sample, which changes every year. The consensus results and the different discrepancies are discussed in an annual meeting. This article illustrates the evolution of the proficiency test through 20 years from different points of view: the increase of participant laboratories, the evolution of the different DNA typing techniques reported by the Ibero-American participant laboratories, the challenges that the proficiency test have met, and future perspectives for a continuous improvement of the proficiency test, especially regarding its accreditation under ISO 17043.

Association of psychiatric consultant characteristics with clinical outcomes of collaborative care for depression.

Context: Adult depression treatment in primary care is improved by integrated behavioral health such as the Collaborative Care Model (CoCM) but outcomes vary across health centers. Objective: Identify CoCM team factors associated with variation in clinical outcomes. Study Design: Correlative study of survey with linked clinical data from routine care. Setting or Dataset: Primary care health centers in Washington state participating in two CoCM implementation and sustainment initiatives (MHIP and BHIP). Clinical data from the Care Management Tracking System (CMTS) used as part of routine clinical care in all sites. Population studied: CoCM clinical teams and adults diagnosed with depression and receiving care from 31 distinct clinic sites throughout Washington state. Instrument: A survey for CoCM Care Managers was developed based on qualitative work exploring CoCM team function in eight domains: overall team function (OTF), psychiatric consultant (PsyC), relationship with primary care physicians (RPCP), role in the practice (RP), training experience (TE), thoughts on CoCM (TOC), leadership support (LS), and overall experience with CoCM (EXP). Outcome Measures: Depression symptoms (PHQ-9) measured as part of regular clinical care. Clinically significant improvements were defined as ≥50% improvement, last PHQ-9 measured <10, and a last PHQ-9 measured <5 (remission). Results: Data from 59 Care Manager surveys and 2509 patients from 31 clinics showed psychometric evidence for the 8 survey domains. Unadjusted multilevel mixed-effects logistic regression found the PsyC domain was associated (p<0.05) with >50% change in PHQ-9 (OR=1.32, p=0.046), last PHQ-9 <10 (OR=1.34, p=0.009), and last PHQ-9 <5 (OR=1.25, p=0.029). Adjusting simultaneously for both clinic-level and patient-level variables, the PsyC domain was significantly associated with likelihood of patient remission (last PHQ-9 <5; OR=1.22, p=0.031). Conclusions: An instrument to assess perceived functioning of the CoCM team had psychometric support. Perceived characteristics of psychiatric consultants was associated with likelihood of depression remission. Characteristics included interest in teaching, commitment to the site, making efforts to have weekly meetings, and willingness to assist care managers on adjustment of treatment strategies. This study is the first to quantify variation in CoCM team functioning with patient outcomes and can be used to inform training and the use of the CoCM.

Initiating antiepilepsy treatment: An update of expert consensus in Spain.

Following publication in 2014 of the International League Against Epilepsy (ILAE) official report changing the definition of epilepsy, a number of questions remain unresolved in regard to deciding when to start treatment and to the choice of a particular antiseizure medication (ASM). This study uses a Delphi method to update consensus among a panel of experts on the initiation of epilepsy treatment in order to provide insight regarding those questions. The study was undertaken in four phases. Firstly, a multi-center steering committee met to review relevant bibliography and to draft a questionnaire. Secondly, a panel of neurologists specialized in epilepsy was selected and convened. Thirdly, an online survey was carried out in two rounds. Fourthly, the final results were discussed at a face-to-face meeting of the steering committee to draw conclusions. The final questionnaire focused on three independent sections: the decision to commence ASM in different clinical situations, the choice of initial monotherapy depending on the type of epilepsy and the patient's age/sex (including childbearing potential), and the choice of initial monotherapy depending on comorbidity. In these two latter sections, fourteen ASMs approved for monotherapy use by the EMA and available in Spain were considered. Regarding the decision as to when to commence treatment, the results show agreement exists to initiate treatment following a first generalized tonic-clonic seizure or a focal seizure if the electroencephalography (EEG) reveals epileptiform activity, if the MRI reveals a lesion, or when it occurs in elderly patients. With respect to the choice of initial monotherapy depending on the type of epilepsy and the patient's age/sex profile, it is agreed to avoid valproic acid (VPA) in women with childbearing potential, with levetiracetam (LEV) and lamotrigine (LTG) being the preferable options in generalized epilepsy. In focal epilepsy, the options are broader, particularly in men, and include the most recent ASMs approved for monotherapy. In the elderly, LEV, lacosamide (LCM), eslicarbazepine acetate (ESL) and LTG are considered the most suitable drugs for initiating treatment. With regard to comorbidities, the recommendation is to avoid enzyme inducing ASMs, with LEV, the most recent ASMs approved for monotherapy and LTG being the preferred options. In conclusion, as the ILAE definition states, there are different situations that lead to treatment initiation after a first seizure. When choosing the first ASM, the type of epilepsy, childbearing potential and drug-drug interaction are key factors.

Clinical evolution of patients treated with aripiprazole long-acting injectable: a preliminary, prospective, observational study.

Objective: To evaluate the effectiveness of 6-month treatment with aripiprazole long-acting injectable (LAI) in improving psychotic symptoms, social functioning and side effects and reducing co-administered antipsychotic drugs.Methods: Multicentre, observational, prospective study that enrolled 53 patients with diagnosis of schizophrenia spectrum disorders who initiated or switched to aripiprazole LAI. The effectiveness of aripiprazole LAI was assessed through the Positive and Negative Syndrome Scale (PANSS), the Udvalg for Kliniske Undersogelser scale for side effects, the Global Assessment of Functioning and the Clinical Global Impression-Schizophrenia (CGI-SCH).Results: Upon treatment with aripiprazole LAI, patients significantly improved all the domains of PANSS (p < .05). Adverse event severity significantly improved after a 6-month aripiprazole LAI treatment (p < .05). Differences from baseline to month 6 in Global Assessment of Functioning score were significant (p = .0002). The proportion of severely ill patients decreased upon treatment with aripiprazole LAI (CGI-SCH scale). Prolactin levels were normalised after a 6-month treatment (from 43.0 to 14.7 ng/mL). Co-administered antipsychotic drugs significantly decreased after a 6-month treatment with aripiprazole LAI.Conclusion: A 6-month treatment with aripiprazole LAI improved the clinical status of our patients without modifying their metabolic profile, and allowed the reduction of co-administered antipsychotic drugs.Practice implicationsLong-acting injectable antipsychotics are effective treatment options for the maintenance of patients with schizophrenia and related disorders, and to ensure treatment adherence. This study describes the evolution of patients over six months of treatment with aripiprazole long-acting injectable. The results from this study support previous data on the efficacy and safety of this atypical antipsychotic. This study may be of wide interest to the community of psychiatrists and may help clinicians optimise treatment adherence in patients with schizophrenia spectrum disorders.Key pointsAripiprazole long-acting injectable is an atypical antipsychotic intended to improve treatment adherence and prevent relapses.This multicentre prospective study evaluated the effectiveness of aripiprazole long-acting injectable over six months of treatment on the control of a comprehensive set of clinical variables.Clinical rating scales showed that treatment with aripiprazole long-acting injectable improved clinical symptoms and social functioning, and reduced the severity of adverse events.Aripiprazole long-acting injectable contributed to the maintenance of adequate metabolic profiles and the normalisation of prolactin levels.Patients significantly decreased co-administered antipsychotic drugs after 6-month treatment with aripiprazole.

Population genetic data of 20 insertion-null allele markers in the Andalusian population.

Genetic data from 21 autosomal insertion-null (INNULs) markers found in the InnoTyper® 21 Human DNA Analysis (InnoGenomics®) was evaluated in 190 unrelated individuals from Andalusia. Allele frequencies and forensic parameters were estimated for the 20 INNULs. All loci were in Hardy-Weinberg equilibrium in the study population after Bonferroni correction and showed no signs of linkage between them. The combined power of discrimination and the power of exclusion for the 20 INNULs were 1-7.42352 × 10-9 and 93.60946%, respectively. These data might be useful for the research of population genetics and for individual identification and paternity testing in forensic science.

Accelerometry-Based Distance Estimation for Ambulatory Human Motion Analysis.

In human motion science, accelerometers are used as linear distance sensors by attaching them to moving body parts, with their measurement axes its measurement axis aligned in the direction of motion. When double integrating the raw sensor data, multiple error sources are also integrated integrated as well, producing inaccuracies in the final position estimation which increases fast with the integration time. In this paper, we make a systematic and experimental comparison of different methods for position estimation, with different sensors and in different motion conditions. The objective is to correlate practical factors that appear in real applications, such as motion mean velocity, path length, calibration method, or accelerometer noise level, with the quality of the estimation. The results confirm that it is possible to use accelerometers to estimate short linear displacements of the body with a typical error of around 4.5% in the general conditions tested in this study. However, they also show that the motion kinematic conditions can be a key factor in the performance of this estimation, as the dynamic response of the accelerometer can affect the final results. The study lays out the basis for a better design of distance estimations, which are useful in a wide range of ambulatory human motion monitoring applications.

Parity and Overweight/Obesity in Peruvian Women.

INTRODUCTION: The rise in noncommunicable diseases and their risk factors in developing countries may have changed or intensified the effect of parity on obesity. We aimed to assess this association in Peruvian women using data from a nationally representative survey. METHODS: We used data from Peru's Demographic and Health Survey, 2012. Parity was defined as the number of children ever born to a woman. We defined overweight as having a body mass index (BMI, kg/m2) of 25.0 to 29.9 and obesity as a BMI ≥30.0. Generalized linear models were used to evaluate the association between parity and BMI and BMI categories, by area of residence and age, adjusting for confounders. RESULTS: Data from 16,082 women were analyzed. Mean parity was 2.25 (95% confidence interval [CI], 2.17-2.33) among rural women and 1.40 (95% CI, 1.36-1.43) among urban women. Mean BMI was 26.0 (standard deviation, 4.6). We found evidence of an association between parity and BMI, particularly in younger women; BMI was up to 4 units higher in rural areas and 2 units higher in urban areas. An association between parity and BMI categories was observed in rural areas as a gradient, being highest in younger women. CONCLUSION: We found a positive association between parity and overweight/obesity. This relationship was stronger in rural areas and among younger mothers.

Genetic variation of 17 STR loci in a Mexican Mestizo population from Mexico City.

Genetic data from 17 autosomal short tandem repeat (STR) loci found in the Powerplex® ESX 17 System (Promega, Madison, WI, USA) was evaluated in 162 unrelated Mexican Mestizo individuals from Mexico City. Allele frequencies and forensic parameters were estimated for the 17 STRs. All loci analyzed were in Hardy-Weinberg equilibrium in the studied population and showed not any signs of linkage between loci. The combined power of discrimination and the power of exclusion for the 16 aSTRs studied were 1-2.56409·10-19 and 99.999938 %, respectively. Genetic distances reveal a close relationship within different populations of Mexican Mestizos. The obtained data might be useful for population genetics research and for individual identification and paternity testing in forensic science.

Adult Prevalence of Epilepsy in Spain: EPIBERIA, a Population-Based Study.

BACKGROUND: This study assesses the lifetime and active prevalence of epilepsy in Spain in people older than 18 years. METHODS: EPIBERIA is a population-based epidemiological study of epilepsy prevalence using data from three representative Spanish regions (health districts in Zaragoza, Almería, and Seville) between 2012 and 2013. The study consisted of two phases: screening and confirmation. Participants completed a previously validated questionnaire (EPIBERIA questionnaire) over the telephone. RESULTS: A total of 1741 valid questionnaires were obtained, including 261 (14.99%) raising a suspicion of epilepsy. Of these suspected cases, 216 (82.75%) agreed to participate in phase 2. Of the phase 2 participants, 22 met the International League Against Epilepsy's diagnostic criteria for epilepsy. The estimated lifetime prevalence, adjusted by age and sex per 1,000 people, was 14.87 (95% CI: 9.8-21.9). Active prevalence was 5.79 (95% CI: 2.8-10.6). No significant age, sex, or regional differences in prevalence were detected. CONCLUSIONS: EPIBERIA provides the most accurate estimate of epilepsy prevalence in the Mediterranean region based on its original methodology and its adherence to ILAE recommendations. We highlight that the lifetime prevalence and inactive epilepsy prevalence figures observed here were compared to other epidemiological studies.

Analysis of factors influencing telephone call response rate in an epidemiological study.

Descriptive epidemiology research involves collecting data from large numbers of subjects. Obtaining these data requires approaches designed to achieve maximum participation or response rates among respondents possessing the desired information. We analyze participation and response rates in a population-based epidemiological study though a telephone survey and identify factors implicated in consenting to participate. Rates found exceeded those reported in the literature and they were higher for afternoon calls than for morning calls. Women and subjects older than 40 years were the most likely to answer the telephone. The study identified geographical differences, with higher RRs in districts in southern Spain that are not considered urbanized. This information may be helpful for designing more efficient community epidemiology projects.

[Superimposed lichen planus pigmentosus]. / Liquen plano pigmentoso sobreimpuesto.

Lichen planus pigmentosus is an uncommon variant of lichen planus that is characterized by the insidious onset of dark brown macules in sun-exposed areas and flexural folds. Superimposed linear lichen planus is an exceedingly rare disorder, but it has been found in both lichen planopilaris and lichen planus types. A 39-year-old woman is presented showing a segmental and linear lichen planus associated with non-segmental lesions meeting all criteria for the diagnosis of superimposed linear planus pigmentosus. The segmental lesions were always more pronounced.

Risk of Parkinson's disease in people aged ≥50 years with new-onset anxiety: a retrospective cohort study in UK primary care.

BACKGROUND: A history of anxiety is more common in people with Parkinson's disease (PD). The prospective risk of PD in those newly presenting with anxiety and factors that increase the risk of PD in patients with anxiety have not been investigated. AIM: To investigate the incidence of PD in people with anxiety aged ≥50 years and clinical features associated with later diagnosis of PD in people with anxiety. DESIGN AND SETTING: A retrospective cohort study using UK primary care data between 2008 and 2018, assessing patients with new-onset anxiety aged ≥50 years. METHOD: Weibull survival regression models were fitted and hazard ratios (HRs) for modelling time-to-PD was estimated in those with and without anxiety, and when determining the risk of developing PD in those with anxiety. Results were adjusted for sociodemographic and lifestyle factors, and relevant physical and mental health conditions. RESULTS: The risk of PD increased two-fold compared with the non-anxiety group after adjustment for age, sex, social deprivation, lifestyle factors, severe mental illness, head trauma, and dementia (HR 2.1, 95% confidence interval = 1.9 to 2.4). In those with anxiety, the presence of depression, hypotension, tremor, rigidity, balance impairment, constipation, sleep disturbance, fatigue, and cognitive impairment were associated with an increased risk of developing PD. CONCLUSION: The risk of developing PD was at least doubled in people with anxiety compared with those without. The clinical features of those who developed PD can help identify patients presenting with anxiety who are in the prodromal phase of PD.
