BACKGROUND: Epidemiological data offer conflicting views of the natural course of binge-eating disorder (BED), with large retrospective studies suggesting a protracted course and small prospective studies suggesting a briefer duration. We thus examined changes in BED diagnostic status in a prospective, community-based study that was larger and more representative with respect to sex, age of onset, and body mass index (BMI) than prior multi-year prospective studies.
METHODS: Probands and relatives with current DSM-IV BED (n = 156) from a family study of BED (\'baseline\') were selected for follow-up at 2.5 and 5 years. Probands were required to have BMI > 25 (women) or >27 (men). Diagnostic interviews and questionnaires were administered at all timepoints.
RESULTS: Of participants with follow-up data (n = 137), 78.1% were female, and 11.7% and 88.3% reported identifying as Black and White, respectively. At baseline, their mean age was 47.2 years, and mean BMI was 36.1. At 2.5 (and 5) years, 61.3% (45.7%), 23.4% (32.6%), and 15.3% (21.7%) of assessed participants exhibited full, sub-threshold, and no BED, respectively. No participants displayed anorexia or bulimia nervosa at follow-up timepoints. Median time to remission (i.e. no BED) exceeded 60 months, and median time to relapse (i.e. sub-threshold or full BED) after remission was 30 months. Two classes of machine learning methods did not consistently outperform random guessing at predicting time to remission from baseline demographic and clinical variables.
CONCLUSIONS: Among community-based adults with higher BMI, BED improves with time, but full remission often takes many years, and relapse is common.

UNASSIGNED: Acute low back pain (LBP) is increasingly recognized for its potential recurrent nature and long-term implications.
UNASSIGNED: This community-based inception cohort study aimed to delineate trajectories of acute LBP over one year and investigate associated biopsychosocial variables.
UNASSIGNED: One hundred seventy-six participants with acute LBP were monitored at 5 follow-up time points over 52 weeks. Pain trajectories were identified using a latent class linear mixed model, and their associations with baseline biopsychosocial factors were evaluated through multinomial logistic regression.
UNASSIGNED: Four distinct LBP trajectories were discerned: \"mild/moderate fluctuating pain\" (54.0%), \"delayed recovery by week 52\" (6.2%), \"persistent moderate pain\" (33.0%), and \"moderate/severe fluctuating pain\" (6.8%). Increased baseline pain intensity and history of LBP episodes were significantly linked with less favorable trajectories. Contrary to expectations, psychological variables like stress, anxiety, and depression did not significantly associate with unfavorable trajectories.
UNASSIGNED: This study underscores the heterogeneity of acute LBP\'s course over a year, challenging the conventionally benign perception of the condition. Recognizing these distinct trajectories might enable more tailored, effective clinical interventions for LBP patients. The small sample size of certain trajectories may influence the generalizability of the results.
UNASSIGNED: Acute LBP can manifest in different trajectories, with nearly half of the participants experiencing less favorable trajectories. Baseline pain intensity and previous episodes of LBP emerged as key factors, whereas psychological variables had no discernible influence. Recognition of these trajectories may be necessary for improved patient management and targeted interventions.

OBJECTIVE: Research on the natural course of symptoms of atypical anorexia nervosa (AN) relative to AN and bulimia nervosa (BN) is limited yet needed to inform nosology and improve understanding of atypical AN. This study aimed to 1) characterize trajectories of eating disorder and internalizing (anxiety, depression) symptoms in college students with and without a history of atypical AN, AN, and BN; and 2) compare sex and race/ethnicity distributions across groups.
METHODS: United States college students who participated in Spit for Science™, a prospective cohort study, were classified as having a history of atypical AN (n = 125), AN (n = 160), BN (n = 617), or as non-eating-disorder controls (NCs, n = 5876). Generalized and linear mixed-effects models assessed group differences in eating and internalizing symptom trajectories, and logistic regression compared groups on sex and race/ethnicity distributions.
RESULTS: Atypical AN participants demonstrated elevated eating disorder and internalizing symptoms compared to NCs during college, but less severe symptoms than AN and BN participants. Although all eating disorder groups showed signs of improvement in fasting and driven exercise, purging and depression remained elevated. Atypical AN participants showed increasing anxiety and stable binge-eating trajectories compared to AN and/or BN participants. The atypical AN group comprised significantly more people of color than the AN group.
CONCLUSIONS: Findings underscore that atypical AN is a severe psychiatric disorder. As atypical AN may present as less severe than AN and BN and disproportionately affects people of color, clinicians should be mindful of biases that could delay diagnosis and care.
UNASSIGNED: College students with histories of atypical AN, AN, and BN demonstrated improvements in fasting and driven exercise and stable purging and depression levels. Atypical AN students showed worsening anxiety and stable binge-eating trajectories compared to favorable changes among AN and BN students. A higher percentage of atypical AN (vs. AN) students were people of color. Findings may improve the detection of atypical AN in college students.

The purpose is to investigate the natural course and long-term prognosis of postpartum depression (PPD). In this retrospective longitudinal cohort study, mothers diagnosed as either suffering from PPD or without PPD were reassessed 5-8 years thereafter by a semi-structured interview and their charts were reviewed for past psychiatric illness prior to the index (initial) episode and for new-onset episodes in the following years. Present psychiatric state was also evaluated by interview and questionnaires. Sixty-five mothers with and 35 without past PPD underwent the full assessment. A total of 66.2% of mothers with past PPD had any axis I psychopathology before their index PPD episode, compared with only 8.6% in the non-PPD group (p < 0.001, φ = .55). Furthermore, 37.2% of the females who had a history of PPD and experienced subsequent childbirths during the follow-up years, developed at least one new episode of PPD. Throughout the 5 years subsequent to the index PPD episode, 42.5% of the PPD group compared with only 3.7% for the non-PPD group developed a new episode of depression (p < 0.001). Lastly, reported psychopathology was higher and functional level was significantly worse in the PPD group at the time of reassessment. Females who develop an episode of PPD show a high degree of subsequent psychopathology and unfavorable prognosis. Clinicians treating females for PPD should consider a longer treatment continuation phase in an effort to prevent further psychopathology and a closer follow-up program.

UNASSIGNED: Warts are very common in military personnel, either at war or during peace times. However, little is known about the prevalence and natural course of warts in military recruits in China.
UNASSIGNED: To investigate the prevalence and natural course of warts in Chinese military recruits.
UNASSIGNED: In this cross-sectional study, the head, face, neck, hands, and feet of 3093 Chinese military recruits aged 16-25 years in Shanghai were examined for the presence of warts upon enlistment medical examinations. Questionnaires were distributed to collect the general information of the participants before the survey. All the patients were followed up by telephone interview for 11-20 months.
UNASSIGNED: The prevalence rate of warts in Chinese military recruits was 2.49%. The diagnosis of most cases was common and plantar warts, which were usually less than 1 cm in diameter and with mild discomfort. Multivariate logistic regression analysis showed that smoking and sharing personal items with others were risk factors. Coming from southern China was a protective factor. Over 2/3 of patients recovered within 1 year and the type, number, and size of warts and treatment choice did not predict resolution.Study limitations and Conclusions This study demonstrated that warts had a relative lower morbidity and a higher spontaneous resolution rate in Chinese military recruits. The telephone interviews following the initial survey and the limitations of a cross-sectional study were the main drawbacks.

The aim was to investigate the effect of modifiable vascular risk factors on the risk of first and recurrent bleeding for patients with a cavernous malformation (CM) of the central nervous system (CNS) over a 10-year period.
A retrospective review of our CM institutional database was performed spanning from 2003 to 2021. The inclusion criteria were non-missing serial magnetic resonance imaging studies and clinical baseline metrics such as vascular risk factors. The exclusion criteria were patients who underwent surgical CM removal and patients with less than a decade of follow-up. Kaplan-Meier and Cox regression analyses were performed to determine the cumulative risk (10 years) of hemorrhage.
Eighty-nine patients with a CM of the CNS were included. Our results showed a non-significant increased risk of hemorrhage during 10 years of follow-up in patients using nicotine (hazard ratio 2.11, 95% confidence interval 0.86-5.21) and in patients with diabetes (hazard ratio 3.25, 95% confidence interval 0.71-14.81). For the presence of modifiable vascular risk factors at study baseline different cumulative 10-year risks of bleeding were observed: arterial hypertension 42.9% (18.8%-70.4%); diabetes 66.7% (12.5%-98.2%); hyperlipidemia 30% (8.1%-64.6%); active nicotine abuse 50% (24.1%-76%); and obesity 22.2% (4%-59.8%). Overall cumulative (10-year) hemorrhage risk was 30.3% (21.3%-41.1%).
The probability of hemorrhage in untreated CNS CM patients increases progressively within a decade of follow-up. None of the modifiable vascular risk factors showed strong indication for an influence on hemorrhage risk, but our findings may suggest a more aggressive course in patients with active nicotine abuse or suffering from diabetes.

The purpose of this study was to investigate the 5-year risk of a third bleeding event in cavernous malformations (CMs) of the central nervous system.
Patients with cerebral or spinal CMs treated between 2003 and 2021 were screened using our institutional database. Patients with a complete magnetic resonance imaging dataset, clinical baseline characteristics, and history of two bleeding events were included. Patients who underwent surgical CM removal were excluded. Neurological functional status was obtained using the modified Rankin Scale score at the second and third bleeding. Kaplan-Meier and Cox regression analyses were performed to determine the cumulative 5-year risk for a third haemorrhage.
Forty-two patients were included. Cox regression analysis adjusted for age and sex did not identify risk factors for a third haemorrhage. 37% of patients experienced neurological deterioration after the third haemorrhage (p = 0.019). The cumulative 5-year risk of a third bleeding was 66.7% (95% confidence interval [CI] 50.4%-80%) for the whole cohort, 65.9% (95% CI 49.3%-79.5%) for patients with bleeding at initial diagnosis, 72.7% (95% CI 39.3%-92.7%) for patients with a developmental venous anomaly, 76.9% (95% CI 55.9%-90.3%) for patients with CM localization to the brainstem and 75% (95% CI 50.6%-90.4%) for patients suffering from familial CM disease.
During an untreated 5-year follow-up after a second haemorrhage, a significantly increased risk of a third haemorrhage compared to the known risk of a first and second bleeding event was identified. The third bleeding was significantly associated with neurological deterioration. These findings may justify a surgical treatment after a second bleeding event.

Visual snow syndrome is characterized by a continuous visual disturbance resembling a badly tuned analogue television and additional visual and non-visual symptoms causing significant disability. The natural course of visual snow syndrome has not hitherto been studied. In this prospective longitudinal study, 78 patients with the diagnosis of visual snow syndrome made in 2011 were re-contacted in 2019 to assess symptom evolution using a semi-structured questionnaire. Forty patients (51% of 78) were interviewed after 84 ± 5 months (mean ± SD). In all patients, symptoms had persisted. Visual snow itself was less frequently rated as the most disturbing symptom (72 versus 42%, P = 0.007), whereas a higher proportion of patients suffered primarily from entopic phenomena (2 versus 17%, P = 0.024). New treatment was commenced in 14 (35%) patients, of whom in seven, visual snow syndrome was ameliorated somewhat. Three (7%) experienced new visual migraine aura without headache, and one (2%) had new migraine headache. There were no differences in the levels of anxiety and depression measured by the Patient Health Questionnaire 8 and the Generalized Anxiety Disorder Scale 7. Thirty-eight patients (49%) were lost to follow-up. In visual snow syndrome, symptoms can persist over 8 years without spontaneous resolution, although visual snow itself might become less bothersome.

OBJECTIVE: The aim of this study was to analyze the impact of OCT characteristics on the natural course of optic disc pit maculopathy (ODP-M).
METHODS: This was a single-center, retrospective, observational case series. Patients with ODP-M were included in the study. Baseline demographic characteristics, central macular thickness (CMT), IPP, subretinal fluid (SRF), subretinal precipitations, outer retinal fluid (ORF), and outer retinal layer hole were evaluated. The changes in the OCT characteristics were analyzed with respect to the best-corrected visual acuity (BCVA) from baseline to the last visit.
RESULTS: Twenty-two eyes of 22 patients were evaluated with a mean follow-up time of 37.6 (median 22) months. The mean BCVA was 0.31 logMAR at baseline and 0.28 logMAR at the final visit (p = 0.521). Baseline BCVA was significantly related to CMT (β coefficient 0.001, p = 0.002). Mean BCVA increased in 7 patients (group 1), remained stable in nine (group 2), and decreased (group 3) in 6 patients. No significant difference was found between the groups regarding the baseline BCVA, CMT, and extent of retinal fluid. In patients with subretinal deposits, BCVA remained stable in 3 patients and worsened in one. ORF was recorded in all patients. In patients with SRF, the mean change of BCVA during follow-up differed significantly, depending on the presence (0.07 logMAR) or absence (-0.125 logMAR) of SRF (p = 0.019).
CONCLUSIONS: Among the OCT characteristics, SRF was a negative prognostic factor in ODP-M. Most ODP-M patients showed improved or stable vision over 3 years of follow-up. Therefore, observation may be considered in patients with reasonable vision and without SRF even when they present with remarkable OCT findings.

BACKGROUND: The management of cervical intraepithelial neoplasia grade 2 is a clinical dilemma. Cervical intraepithelial neoplasia grade 3 is considered a cancer precursor and is always treated with excision. Most of the cervical intraepithelial neoplasia grade 1 cases regress spontaneously, and it is internationally mostly monitored with expectant management. Surgical treatment of cervical intraepithelial neoplasia entails increased risk of preterm birth in future pregnancies. Cervical intraepithelial neoplasia grade 2 in women aged under 25 years is quite well-studied; the regression rate is high and the cervical cancer risk is low. Cervical intraepithelial neoplasia grade 2 in women aged 25 years and above, in whom the risk of occult cancer is higher, has been less studied.
OBJECTIVE: This study aimed to evaluate the natural course, over 2 years, of untreated cervical intraepithelial neoplasia grade 2 in women aged 25 to 30 years and its association with human papillomavirus 16.
METHODS: The study was conducted as a prospective longitudinal multicenter clinical study during February 2017 to June 2021 at 5 colposcopy clinics managing referrals after abnormal cervical screening in Region Västra Götaland, Sweden. The per protocol group comprised 127 women, aged 25 to 30 years, with fully visible squamocolumnar junction and histologically verified cervical intraepithelial neoplasia grade 2. The patients were followed up for 2 years with colposcopy, cytology, human papillomavirus tests, and at least 2 cervical biopsies every 6 months until progression or regression. The main outcome measures were the rates of regression of cervical intraepithelial neoplasia grade 2 at 6, 12, 18, and 24 months in cases with human papillomavirus 16 and those without human papillomavirus 16. The secondary outcomes were persistence and progression.
RESULTS: In the per protocol analysis, partial or total regression during the 2-year period was found in 72% of patients (95% confidence interval, 63-79). In patients with human papillomavirus 16, the regression rate was 51% (95% confidence interval, 36-66) and the progression rate was 47% (95% confidence interval, 32-62). In the human papillomavirus-non-16 group, 83% (95% confidence interval, 73-90) regressed and 16% (95% confidence interval, 9-26) progressed. Most of the regression and progression in both the groups occurred within 15 months. The difference in regression between human papillomavirus 16 and human papillomavirus-non-16 cases was statistically significant (P value=.0001), as was the difference in progression (P=.0002).
CONCLUSIONS: The regression rate of cervical intraepithelial neoplasia grade 2 is high, and human papillomavirus 16 is a strong determinant of the natural course. Patients aged 25 to 30 years with a fully visible squamocolumnar junction and without human papillomavirus 16 should generally be recommended active surveillance for 15 months, whereas immediate treatment should be considered in cases with human papillomavirus 16.
