A Predictive Model for Thiamine Responsive Disorders Among Infants and Young Children: Results from a Prospective Cohort Study in Lao People's Democratic Republic.

OBJECTIVE: To develop a predictive model for thiamine responsive disorders (TRDs) among infants and young children hospitalized with signs or symptoms suggestive of thiamine deficiency disorders (TDDs) based on response to therapeutic thiamine in a high-risk setting. STUDY DESIGN: Children aged 21 days to <18 months hospitalized with signs or symptoms suggestive of TDD in northern Lao People's Democratic Republic were treated with parenteral thiamine (100 mg daily) for ≥3 days in addition to routine care. Physical examinations and recovery assessments were conducted frequently for 72 hours after thiamine was initiated. Individual case reports were independently reviewed by three pediatricians who assigned a TRD status (TRD or non-TRD), which served as the dependent variable in logistic regression models to identify predictors of TRD. Model performance was quantified by empirical area under the receiver operating characteristic curve. RESULTS: A total of 449 children (median [Q1, Q3] 2.9 [1.7, 5.7] months old; 70.3% exclusively/predominantly breastfed) were enrolled; 60.8% had a TRD. Among 52 candidate variables, those most predictive of TRD were exclusive/predominant breastfeeding, hoarse voice/loss of voice, cyanosis, no eye contact, and no diarrhea in the previous 2 weeks. The area under the receiver operating characteristic curve (95% CI) was 0.82 (0.78, 0.86). CONCLUSIONS: In this study, the majority of children with signs or symptoms of TDD responded favorably to thiamine. While five specific features were predictive of TRD, the high prevalence of TRD suggests that thiamine should be administered to all infants and children presenting with any signs or symptoms consistent with TDD in similar high-risk settings. The usefulness of the predictive model in other contexts warrants further exploration and refinement. TRIAL REGISTRATION: Clinicaltrials.gov NCT03626337.

Exploring the cell interactome: deciphering relative impacts of cell-cell communication in cell co-culture using a novel microfluidic device.

The human body is made up of approximately 40 trillion cells in close contact, with the cellular density of individual tissues varying from 1 million to 1 billion cells per cubic centimetre. Interactions between different cell types (termed heterotypic) are thus common in vivo. Communication between cells can take the form of direct cell-cell contact mediated by plasma membrane proteins or through paracrine signalling mediated through the release, diffusion, and receipt of soluble factors. There is currently no systematic method to investigate the relative contributions of these mechanisms to cell behaviour. In this paper, we detail the conception, development and validation of a microfluidic device that allows cell-cell contact and paracrine signalling in defined areas and over a variety of biologically relevant length scales, referred to as the interactome-device or 'I-device'. Importantly, by intrinsic device design features, cells in different regions in the device are exposed to four different interaction types, including a) no heterotypic cell interaction, b) only paracrine signalling, c) only cell-cell direct contact, or d) both forms of interaction (paracrine and cell-cell direct contact) together. The device design was validated by both mathematical modelling and experiments. Perfused stem cell culture over the medium term and the formation of direct contact between cells in the culture chambers was confirmed. The I-device offers significant flexibility, being able to be applied to any combination of adherent cells to determine the relative contributions of different communication mechanisms to cellular outcomes.

Risk factors for anaemia among women and their young children hospitalised with suspected thiamine deficiency in northern Lao PDR.

Anaemia among women and young children remains a major public health concern. This secondary study describes the anaemia prevalence among young hospitalised children and their mothers in northern Lao People's Democratic Republic and explores possible nutritional causes and risk factors for anaemia. Hospitalised children (ages 21 days to <18 months) with clinical symptoms suggestive of thiamine deficiency disorders were eligible along with their mothers. Venous blood was collected for determination of haemoglobin, ferritin, soluble transferrin receptor (sTfR), retinol-binding protein (RBP), erythrocyte glutathione reductase activation coefficient (EGRac), thiamine diphosphate (ThDP) and acute phase proteins. Risk factors for anaemia were modelled using minimally adjusted logistic regression controlling for age. Haemoglobin results were available for 436 women (mean ± SD age 24.7 ± 6.4 years; 1.6% pregnant) and 427 children (4.3 ± 3.5 months; 60.3% male). Anaemia prevalence (Hb < 120 g/L for nonpregnant women and <110 g/L for pregnant women and children) was 30.7% among women and 55.2% among children. In bivariate analyses, biomarkers significantly associated with anaemia in women were ferritin, sTfR, RBP, EGRac and ThDP. Other risk factors for women were lower BMI, mid-upper arm circumference < 23.5 cm, lower education, lower socioeconomic index, food insecurity, Hmong ethnicity, not/rarely having attended antenatal care, not having taken antenatal iron-containing supplements and not meeting minimum dietary diversity. Risk factors for anaemia among children were older age, male sex, stunting, sTfR, ThDP and alpha-1-acid-glycoprotein. Anaemia was common among women and their hospitalised children and was associated with micronutrient deficiencies and socioeconomic, dietary and health care-seeking risk factors, suggesting that multiple strategies are required to prevent anaemia among women and children.

Association of Migraine and Vasomotor Symptoms.

OBJECTIVE: To further examine a potential link between migraine and vasomotor symptoms as well as hypertension as a cardiovascular disease risk factor, potentially explaining the association in midlife women. PATIENTS AND METHODS: We conducted a cross-sectional analysis from the Data Registry on Experiences of Aging, Menopause, and Sexuality using questionnaire data from women aged 45 to 60 years seen in women's clinics at a tertiary care center from May 15, 2015, through January 31, 2022. A history of migraine was self-reported; menopause symptoms were assessed with the Menopause Rating Scale. Associations between migraine and vasomotor symptoms were evaluated utilizing multivariable logistic regression models adjusting for multiple factors. RESULTS: Of 5708 women included in the analysis, 1354 (23.7%) reported a migraine history. The total cohort had a mean age of 52.8 years, most (5184 [90.8%]) were White, and 3348 (58.7%) were postmenopausal. In adjusted analysis, women with migraine were significantly more likely to have severe/very severe hot flashes vs no hot flashes compared with women without migraine (odds ratio, 1.34; 95% CI, 1.08 to 1.66; P=.007). Migraine was associated with a diagnosis of hypertension in adjusted analysis (odds ratio, 1.31; 95% CI, 1.11 to 1.55; P=.002). CONCLUSION: This large cross-sectional study confirms an association between migraine and vasomotor symptoms. Migraine also was associated with hypertension, potentially providing a link with cardiovascular disease risk. Given the high prevalence of migraine in women, this association may help identify those at risk for more severe menopause symptoms.

Nutrition and health-seeking practices during pregnancy and lactation and potential strategies to increase micronutrient intakes among women in northern Lao PDR.

Access to and utilisation of antenatal care (ANC) is important for optimising health and nutrition during pregnancy. This study aimed to assess adherence to and factors associated with ANC and antenatal supplement use among Laotian women, and consider culturally appropriate strategies to increase micronutrient intakes. Mother-child (aged 21 d to <18 months) dyads (n 699) enrolled in a hospital-based prospective cohort study with the community comparison group in Luang Prabang province were interviewed about their antenatal history, supplement use, household sociodemographic and dietary practices, including postpartum food avoidances. Ninety percent of women (mean age 24⋅7 ± 6⋅3 years) reported receiving ANC during their pregnancy, with the majority reporting four to seven contacts, while 84⋅6 and 17⋅3 % reported supplement use during pregnancy and lactation, respectively. Adequate ANC contacts (≥8) and supplement use was more likely among women with complete primary education and from higher socioeconomic status households, and less likely among women belonging to ethnic minority populations and those who delivered their child at home. All women continued to consume salt while adhering to postpartum food avoidances; however, 58⋅5 and 38⋅7 % of habitual consumers restricted fish and soy sauces, respectively. Eighty-six percent of women reported they would be willing to take supplements when adhering to postpartum dietary restrictions. Overall, women's reported ANC attendance and antenatal supplement use was suboptimal. Understanding predictors of and barriers to ANC and supplement use may help implement effective public health strategies to improve adherence. Alongside targeted supplementation, salt fortification with micronutrients may be a viable population-wide intervention that needs further evaluation.

Evaluating the Link Between Self-Reported Endometriosis and Female Sexual Dysfunction.

BACKGROUND: Studies have found that women with endometriosis have a higher risk of female sexual dysfunction (FSD). AIM: To evaluate the relationship between self-reported endometriosis and FSD utilizing validated surveys. METHODS: A cross-sectional analysis was conducted among sexually active women aged 18-90 who presented to 3 Mayo Clinic sites from 2015 to 2021. FSD was determined utilizing a combined endpoint of Female Sexual Function Index score ≤ 26.55 and Female Sexual Distress Scale-Revised score ≥ 11. Associations between history of endometriosis and FSD were evaluated by fitting 3 multivariable logistic models and were stratified by menopause status. In the first model, the association was adjusted for age, BMI, race/ethnicity, marital status, and education. The second model adjusted for the variables in Model 1 and hormone therapy, hormonal contraceptive use, self-reported history of abuse within the last year, and co-morbidities including the history of diabetes, heart disease, hypertension, osteoporosis, and stroke. The third model adjusted for the variables in Model 1, Model 2, and anxiety, depression, relationship satisfaction, and SSRI/SNRI use. OUTCOMES: The outcomes included self-reported endometriosis and female sexual dysfunction determined utilizing a combined endpoint of Female Sexual Function Index score ≤ 26.55 and Female Sexual Distress Scale-Revised score ≥ 11. RESULTS: Of 7118 patients (mean age 51.3), 92.2% were white, 78.4% were peri- or postmenopausal, 8.7% reported endometriosis history, and 57.2% met the criteria for FSD. Women with endometriosis were more likely to be overweight or obese, be smokers, have had a history of heart disease and osteoporosis, have had anxiety and depressed mood, have had a hysterectomy and bilateral salpingo-oophorectomy, and have used hormone therapy. Compared to those without endometriosis, women with endometriosis were significantly more likely to have FSD only among premenopausal women (74.2% vs 57.4%). Similarly, in multivariable analysis the relationship was only seen for premenopausal women in all 3 models (Model 1: OR 2.74 (95% CI 1.43-5.27); Model 2: OR 2.55 (95% CI 1.30-5.04); Model 3: OR 2.30 (95% CI 1.13-4.68)). CLINICAL IMPLICATIONS: These findings highlight the opportunity for healthcare practitioners to evaluate sexual function in premenopausal women with endometriosis. For peri and postmenopausal women with endometriosis, the risk of FSD was lower than for premenopausal women with endometriosis. STRENGTHS AND LIMITATIONS: This study analyzed the association between endometriosis and FSD in women by menopause status using validated tools that included a measure of distress associated with sexual dysfunction. Limitations include its cross-sectional design which does not allow for determination of the direction of this association. CONCLUSION: The risk for FSD associated with endometriosis depends on menopause status. Endometriosis increased the odds of FSD only in premenopausal women. Kling JM, Ghaith S, Smith T, et al.

Sexual dysfunction in female cancer survivors: Addressing the problems and the remedies.

This narrative review examines current evidence regarding sexual function in female cancer survivors, focusing on the impact of cancer treatments as well as the evaluation and management of sexual concerns in this population. Sexual dysfunction in female cancer survivors is prevalent, yet underdiagnosed and undertreated. Many healthcare professionals feel ill-equipped to address the sexual health needs of female cancer survivors. Multiple direct and indirect factors can contribute to sexual dysfunction in female cancer survivors, including effects on the hormonal milieu and physical and sexual well-being. Factors influencing sexual function after cancer may be multifaceted, warranting a multidisciplinary approach to care. Validating and normalizing sexual health concerns and providing education and appropriate therapies, as well as timely referral to appropriate sexual health experts, are key to optimizing cancer survivorship care in women. Clinicians should, at a minimum, be aware of the various potential treatment modalities, taking into account contributing physical, psychological and interpersonal factors. Management of sexual health concerns should be individualized based on contributing factors.

A Clinical Review on Paroxetine and Emerging Therapies for the Treatment of Vasomotor Symptoms.

Most women experience vasomotor symptoms (VMS) during their menopausal transition. Menopausal hormone therapy (HT) is the most effective treatment for VMS, but some women choose not to use HT or have contraindications to using HT. Non-hormonal treatment options should be offered to these symptomatic menopausal women. Multiple large randomized controlled trials have demonstrated statistically significant reductions in hot flash severity and/or frequency with the use of selective serotonin reuptake inhibitors (SSRIs) and serotonin norepinephrine reuptake inhibitors (SNRIs). To date, paroxetine mesylate remains the only non-hormonal treatment that has been approved by the United States Food and Drug Administration (FDA) for the management of moderate to severe postmenopausal vasomotor symptoms. Lower doses are needed to reduce VMS than those used to treat anxiety or depression, which is beneficial since side effects are typically dose dependent. The recommended dosage is 7.5 mg once daily at bedtime. Dose dependent side effects include nausea, fatigue, and dizziness. Knowing potential medication interactions is critical such as with medications that can lead to serotonin syndrome, concomitant use with monoamine oxidase inhibitors and being aware of p450 drug metabolism is essential for patients taking drugs that utilize the CYP2D6 enzyme for metabolism including tamoxifen. This review discusses in detail the available data supporting the use of paroxetine for the treatment of VMS, including side effects and considerations regarding prescribing. A discussion of other emerging treatments is included as well, including estetrol, oxybutynin and neurokinin 3 (NK3) receptor antagonists.

Cardiovascular Disease Screening in Women: Leveraging Artificial Intelligence and Digital Tools.

Cardiovascular disease remains the leading cause of death in women. Given accumulating evidence on sex- and gender-based differences in cardiovascular disease development and outcomes, the need for more effective approaches to screening for risk factors and phenotypes in women is ever urgent. Public health surveillance and health care delivery systems now continuously generate massive amounts of data that could be leveraged to enable both screening of cardiovascular risk and implementation of tailored preventive interventions across a woman's life span. However, health care providers, clinical guidelines committees, and health policy experts are not yet sufficiently equipped to optimize the collection of data on women, use or interpret these data, or develop approaches to targeting interventions. Therefore, we provide a broad overview of the key opportunities for cardiovascular screening in women while highlighting the potential applications of artificial intelligence along with digital technologies and tools.

Traditional prenatal and postpartum food restrictions among women in northern Lao PDR.

Culturally determined food restrictions are common among pregnant and postpartum women in Asia. This study aimed to describe perinatal dietary restrictions, factors associated with food avoidances and attainment of minimum dietary diversity (MDD-W) among women in Lao PDR. Mother-child (aged 21 days to <18 months) dyads (n = 682) were enrolled into a cohort study in northern Lao PDR and interviewed at one time point postpartum. During pregnancy and postpartum, 1.6% and 97% of women reported following dietary restrictions, respectively. Cluster analysis identified four distinct postpartum dietary patterns: most restrictive (throughout first 2 months postpartum); least restrictive; 2 weeks highly restrictive and 1 month highly restrictive, followed by 19%, 15%, 5% and 62% of women, respectively. Greater maternal age, gravidity and higher household socioeconomic status were associated with allowing more diverse foods, while women from food insecure households followed more restrictive diets for longer. Women belonging to the Hmong ethnic group followed a highly restrictive diet of white rice and chicken for the first month postpartum. MDD-W was achieved by 10% of women restricting their diet at the time of the interview compared with 17% of women who were consuming their normal diet (p = 0.04). Postpartum dietary restrictions are widespread among women in northern Lao PDR. These highly restrictive diets, low dietary diversity and food insecurity likely contribute to micronutrient deficiencies in women that may have important consequences for their breastfed infants through reduced breastmilk micronutrient content, which requires further exploration. Culturally appropriate strategies to increase micronutrient intakes among women should be considered.

Assessing age, breeding stage, and mating activity as drivers of variation in the reproductive microbiome of female tree swallows.

Sexually transmitted microbes are hypothesized to influence the evolution of reproductive strategies. Though frequently discussed in this context, our understanding of the reproductive microbiome is quite nascent. Indeed, testing this hypothesis first requires establishing a baseline understanding of the temporal dynamics of the reproductive microbiome and of how individual variation in reproductive behavior and age influence the assembly and maintenance of the reproductive microbiome as a whole. Here, we ask how mating activity, breeding stage, and age influence the reproductive microbiome. We use observational and experimental approaches to explain variation in the cloacal microbiome of free-living, female tree swallows (Tachycineta bicolor). Using microsatellite-based parentage analyses, we determined the number of sires per brood (a proxy for female mating activity). We experimentally increased female sexual activity by administering exogenous 17ß-estradiol. Lastly, we used bacterial 16S rRNA amplicon sequencing to characterize the cloacal microbiome. Neither the number of sires per brood nor the increased sexual activity of females significantly influenced female cloacal microbiome richness or community structure. Female age, however, was positively correlated with cloacal microbiome richness and influenced overall community structure. A hypothesis to explain these patterns is that the effect of sexual activity and the number of mates on variation in the cloacal microbiome manifests over an individual's lifetime. Additionally, we found that cloacal microbiome alpha diversity (Shannon Index, Faith's phylogenetic distance) decreased and community structure shifted between breeding stages. This is one of few studies to document within-individual changes and age-related differences in the cloacal microbiome across successive breeding stages. More broadly, our results contribute to our understanding of the role that host life history and behavior play in shaping the cloacal microbiomes of wild birds.

Note-taking by nursing students: the case for implementing writing strategies to encourage best practice.

BACKGROUND: Note-taking is an integral component of professional nursing practice. If students are to complete this effectively, a range of teaching, learning and assessment strategies are required to support their development of this skill. OBJECTIVES: This study aimed to identify lecturers' perspectives of students' note-taking on placement to identify factors that limit the development of this skill; these perspectives could be used to explore strategies to support students to develop this skill while at university. DESIGN: A qualitative study taking a phenomenological approach was carried out. PARTICIPANTS: Three senior nursing practice visitors agreed to be interviewed. METHODS: Semistructured interviews were carried out and thematic analysis carried out to explore lecturers' perspectives of students' experiences of note-taking while on placement. These interviews were intended to obtain detailed accounts of note-taking and allow challenges to be explored. RESULTS: Each participant observed and supported students' note-taking within practice placement settings. Three main themes emerged from the data: limitations to students' vocabulary and literacy; inconsistency between trusts resulting in an inability to articulate experience; and note-taking clarity and accuracy. CONCLUSION: Note-taking is central to nurses' education and professional documentation to support best practice and high-quality patient care. Variations in processes between trusts, stringency of standards required by the trusts where students attend placements, and students' writing abilities differ widely, which directly affect the consistency and accuracy of written notes.

Prescribing testosterone and DHEA: The role of androgens in women.

In women, the androgens testosterone and dehydroepiandrosterone (DHEA) play important physiologic roles in reproductive tissues, mood, cognition, the breast, bone, muscle, vasculature, and other systems. This article reviews the effects of androgens in women, as well as the indications and best-practice recommendations for the use of androgen therapy.

Thiamine fortification strategies in low- and middle-income settings: a review.

Thiamine (vitamin B1 ) is an essential micronutrient in energy metabolism and cognitive and neurological health. Thiamine deficiency disorders (TDDs) have a range of clinical presentations that result in various morbidities and can be fatal if not promptly recognized and treated, especially in infants. To intervene, thiamine intakes by breastfeeding mothers and others at risk of thiamine deficiency should be increased to ensure adequate thiamine intake. Although thiamine fortification programs have a long history in high-income countries, there are few mandatory fortification programs to address TDDs in low- and middle-income countries (LMICs), particularly in the regions of greatest concern, South and Southeast Asia. This review highlights essential aspects for consideration in the development of a mandatory fortification program in LMICs, including an overview of the data required to model fortification dosing schemes, available thiamine fortificants, and potential fortification vehicles, as well as identifies current knowledge gaps.

Thiamine deficiency disorders: a clinical perspective.

Thiamine is an essential water-soluble vitamin that plays an important role in energy metabolism. Thiamine deficiency presents many challenges to clinicians, in part due to the broad clinical spectrum, referred to as thiamine deficiency disorders (TDDs), affecting the metabolic, neurologic, cardiovascular, respiratory, gastrointestinal, and musculoskeletal systems. Concurrent illnesses and overlapping signs and symptoms with other disorders can further complicate this. As such, TDDs are frequently misdiagnosed and treatment opportunities missed, with fatal consequences or permanent neurologic sequelae. In the absence of specific diagnostic tests, a low threshold of clinical suspicion and early therapeutic thiamine is currently the best approach. Even in severe cases, rapid clinical improvement can occur within hours or days, with neurological involvement possibly requiring higher doses and a longer recovery time. Active research aims to help better identify patients with thiamine-responsive disorders and future research is needed to determine effective dosing regimens for the various clinical presentations of TDDs. Understanding the clinical diagnosis and global burden of thiamine deficiency will help to implement national surveillance and population-level prevention programs, with education to sensitize clinicians to TDDs. With concerted effort, the morbidity and mortality related to thiamine deficiency can be reduced.

Contemporary Non-hormonal Therapies for the Management of Vasomotor Symptoms Associated with Menopause: A Literature Review.

Nearly 75% of all menopausal women experience bothersome vasomotor symptoms including hot flushes and night sweats. Yet vasomotor symptoms continue to be an undertreated and underdiagnosed symptom of menopause which can negatively affect a woman's overall quality of life. While hormone therapy has been widely utilized to ameliorate hot flushes, not all women are candidates for use, especially those with increased risk of cardiovascular disease, thromboembolic disease, and/or women at an increased risk of certain hormone-dependent cancers. The current literature provides strong evidence for non-hormonal therapies in women who experience vasomotor symptoms. This article reviews the evidence for the use of non-hormonal pharmacologic therapies for the treatment of menopausal symptoms including antidepressants, gabapentinoids, clonidine and anticholinergics. We also review data on emerging therapies including the latest evidence on neurokinin-1 and -3 antagonists. These therapies should be considered when hormonal options are contraindicated and/or not preferred by the patient. While there are many options available, clinicians should individualize therapy based on the patient's needs and goals while mitigating bothersome side effects.

Postmenopausal Hormone Therapy-Local and Systemic: A Pharmacologic Perspective.

Every woman, if she lives long enough, will transition into menopause, and as the US population ages, women will be spending more time in a postmenopausal state than before. For postmenopausal women, the decision to initiate menopausal hormone therapy should be individualized. A thorough evaluation of the patient's cardiovascular, venous thromboembolic, cancer, and fracture risk should be considered along with the woman's quality of life. Hormone therapy exerts its therapeutic effects on vasomotor symptoms, the skeleton, and the genitourinary system independent of age since menopause and these benefits are lost once hormone therapy is stopped. Here we review the pharmacologic properties dose, formulation, mode of administration, timing of initiation, and duration of hormonal therapies in regard to optimizing benefit and minimizing risk to the patient. This discussion will focus on the effects of common hormonal therapies including estrogen (local and systemic), progesterone, estrogen receptor agonist/antagonist, and local dehydroepiandrosterone and include a brief review of compounded bioidentical hormone therapy.

Establishing a case definition of thiamine responsive disorders among infants and young children in Lao PDR: protocol for a prospective cohort study.

INTRODUCTION: Diagnosis of infantile thiamine deficiency disorders (TDD) is challenging due to the non-specific, highly variable clinical presentation, often leading to misdiagnosis. Our primary objective is to develop a case definition for thiamine responsive disorders (TRD) to determine among hospitalised infants and young children, which clinical features and risk factors identify those who respond positively to thiamine administration. METHODS AND ANALYSIS: This prospective study will enrol 662 children (aged 21 days to <18 months) seeking treatment for TDD symptoms. Children will be treated with intravenous or intramuscular thiamine (100 mg daily for a minimum of 3 days) alongside other interventions deemed appropriate. Baseline assessments, prior to thiamine administration, include a physical examination, echocardiogram and venous blood draw for the determination of thiamine biomarkers. Follow-up assessments include physical examinations (after 4, 8, 12, 24, 36, 48 and 72 hours), echocardiogram (after 24 and 48 hours) and one cranial ultrasound. During the hospital stay, maternal blood and breast-milk samples and diet, health, anthropometric and socio-demographic information will be collected for mother-child pairs. Using these data, a panel of expert paediatricians will determine TRD status for use as the dependent variable in logistic regression models. Models identifying predictors of TRD will be developed and validated for various scenarios. Clinical prediction model performance will be quantified by empirical area under the receiver operating characteristic curve, using resampling cross validation. A frequency-matched community-based cohort of mother-child pairs (n=265) will serve as comparison group for evaluation of potential risk factors for TRD. ETHICS AND DISSEMINATION: Ethical approval has been obtained from The National Ethics Committee for Health Research, Ministry of Health, Lao PDR and the Institutional Review Board of the University of California Davis. The results will be disseminated via scientific articles, presentations and workshops with representatives of the Ministry of Health. TRIAL REGISTRATION NUMBER: NCT03626337.

The Positive Predictive Value of Smartphone Photoscreening in Pediatric Practices.

PURPOSE: To compare smartphone photoscreening with other commercial objective screeners for amblyopia screening for young children. METHODS: Ten pediatricians in four practices employed Nokia 1020 smartphones (Espoo, Finland) with single-axis Gobiquity software (Scottsdale, AZ) during well-child visits. Outcomes of confirmatory pediatric ophthalmology examinations were prospectively compared using American Association for Pediatric Ophthalmology and Strabismus uniform standards. RESULTS: Five percent of 6,310 in-office screenings were referred: 25% for high anisometropia, 31% for hyperopia, and 15% for myopia. The positive predictive value (PPV) in 217 follow-up examinations was 68% (95% confidence interval: 62% to 74%) by 2013 age-stratified standards and 77% (confidence interval: 71% to 83%) by 2003 American Association for Pediatric Ophthalmology and Strabismus standards. The follow-up rate was 65%. CONCLUSIONS: Smartphone photoscreening had PPV comparable with other commercial objective screeners. Simple, valid photoscreeners should help pediatricians achieve widespread compliance with screening guidelines to reduce the burden of pediatric amblyopia vision impairment.
