Półilościowa ocena hirsutyzmu u 850 pacjentek z zespołem policystycznych jajników i 2988 kobiet z grupy kontrolnej w Chinach
Introduction: There is considerable individual and racial variation in the degree and pattern of body hair among PCOS patients. The purposes of this study were to define: 1) a suitable standard of hirsutism for Chinese women with PCOS and the general Chinese population; 2) the characteristics of hair distribution and degree in Chinese women with PCOS and the general population; and 3) the correlation of PCOS and FG score in Chinese women.Material and methods: This retrospective study in Chinese women with PCOS in the reproductive centre of Sun Yat-Sen Memorial Hospital, Sun Yat-Sen University, comprised 850 patients with PCOS and 2,988 members of the general population. It was conducted crosssectionally by interview, physical examination, ultrasound scan, and modified Ferriman-Gallwey score. Eight hundred and fifty Chinese women with PCOS (aged 20–41) underwent an interview, blood drawing, physical and ultrasound examination. Body hair at nine sites (lip, chin, arm, thigh, chest, upper belly, lower belly, upper back and lower back) were evaluated using the scoring system described by Ferriman and Gallwey; 2,988 healthy women (aged 20–45) underwent an interview, physical examination, ultrasound scan and FG score evaluation by trained gynaecologists. Terminal body hair growth was assessed using the mFG scoring system in Chinese women with PCOS and the control group; nine body areas were scored from 0–4 for terminal hair growth distribution.Results: Our findings showed that of the 850 patients, 367 had a FG score equal to or greater than 5 points [43.2% (367/850)], 282 patients had a FG score equal to or greater than 6 points [33.18% (282/850)], and 21% had a score of at least 8 points. Nobody’s FG score was equal to or greater than 24 points. Hirsutism was significantly higher in PCOS patients (score≥ 5 = 43.2%) than in the general population (score ≥ 5 = 10%). The lip is the most common place (score 0–3) where terminal hair grows in 850 PCOS patients and the general population. Next came the upper back and chest, and the number of 4 points was only recorded for the region of the lip (16), thigh (3), lower belly (3), arm (1), chest (1), and lower back (1). None of the PCOS patients displayed a score of more than 4 points for the chin, upper belly and upper back.Conclusions: Our data indicates that: 1) an mFG score of 5 or above is out of the norm for the general unselected population and forms almost half of the possibility of diagnosing PCOS in Chinese women; 2) lips and upper back are the most common places that hair grows (score 1–2), but in terms of the serious situation (score 3–4), lips and thighs are the most common places that hair grows; 3) there is a good predictive value to diagnose PCOS by FG score for Chinese people; and 4) hirsutism is more common in PCOS than in the general population in China.

Cele tego badania obejmowały określenie: 1) odpowiedniego standardu hirsutyzmu u Chinek z PCOS i w populacji ogólnej; 2) charakterystyki rozkładu i nasilenia owłosienia u Chinek z PCOS i w populacji ogólnej; oraz 3) korelacji między PCOS a wynikiem w skali Ferrimana-Gallweya (FG) u Chinek.Materiał i metody: Retrospektywnym badaniem w populacji Chinek z PCOS w ośrodku leczenia zaburzeń rozrodu w Sun Yat-Sen Memorial Hospital, Sun Yat-Sen University, objęto 850 pacjentek z PCOS i 2988 kobiet z populacji ogólnej, u których dokonano oceny na podstawie wywiadów, badania przedmiotowego, oceny ultrasonograficznej oraz zmodyfikowanej skali FG. U 850 Chinek z PCOS (wiek 20-41 lat) zebrano wywiady, pobrano krew, przeprowadzono badanie fizykalne i ultrasonograficzne oraz oceniono owłosienie ciała w 9 miejscach (warga, podbródek, ramię, udo, klatka piersiowa, nadbrzusze, podbrzusze oraz górna i dolna część pleców), posługując się systemem punktowym opisanym przez Ferrimana i Gallweya, a u 2988 zdrowych kobiet (wiek 20–45 lat) zebrano wywiady, przeprowadzono badanie fizykalne i ultrasonograficzne oraz dokonano oceny w skali FG. Ocena była dokonywana przez wyszkolonych ginekologów. Wzrost i rozkład włosów końcowych na ciele oceniono za pomocą zmodyfikowanej skali FG u Chinek z PCOS oraz w grupie kontrolnej, określając wartości punktowe w skali od 0 do 4 dla dziewięciu okolic ciała.Wyniki: Wśród 850 pacjentek z PCOS wynik ≥ 5 punktów w skali FG uzyskano u 367 pacjentek [43,2% (367/850)], wynik ≥ 6 punktów u 282 pacjentek [33,18% (282/850)], a co najmniej 8 punktów u 21% pacjentek. U żadnej pacjentki nie uzyskano wyniku ≥ 24 punkty. Nasilenie hirsutyzmu było istotnie większe wśród pacjentek z PCOS (wynik ≥ 5 punktów u 43,2%) niż w populacji ogólnej (wynik ≥ 5 punktów u 10%). Warga była najczęstszym miejscem wzrostu włosów końcowych (wynik 0–3 pkt.) u 850 pacjentek z PCOS oraz w populacji ogólnej, a następne miejsca pod względem częstości wzrostu włosów zajęły górna część pleców i klatka piersiowa. Wzrost włosów oceniony na 4 punkty odnotowano tylko w okolicach wargi (n = 16), uda (n = 3), podbrzusza (n = 3), ramion (n = 1), klatki piersiowej (n = 1) oraz dolnej części pleców (n = 1). U żadnej z pacjentek z PCOS nie odnotowano wzrostu włosów ocenionego na 4 punkty w okolicach podbródka, nadbrzusza i górnej części pleców.Wnioski: Nasze dane wskazują, że: 1) wynik w zmodyfikowanej skali FG wynoszący ≥ 5 punktów jest poza normą w nieselekcjonowanej populacji ogólnej i stwierdza się go u prawie połowy Chinek z rozpoznaniem PCOS; 2) warga i górna część pleców były najczęstszymi miejscami wzrostu włosów (wynik 1–2 pkt.), ale najbardziej nasilony wzrost (wynik 3–4 pkt.), stwierdzono w obrębie wargi i ud; 3) Rozpoznawanie PCOS na podstawie wyniku w skali FG u Chinek charakteryzuje się dobrą wartością predykcyjną; 4) hirsutyzm u Chinek jest częstszy wśród pacjentek z PCOS niż w populacji ogólnej.

Engineered lentivector targeting of dendritic cells for in vivo immunization
We report a method of inducing antigen production in dendritic cells by in vivo targeting with lentiviral vectors that specifically bind to the dendritic cell–surface protein DC-SIGN. To target dendritic cells, we enveloped the lentivector with a viral glycoprotein from Sindbis virus engineered to be DC-SIGN–specific. In vitro, this lentivector specifically transduced dendritic cells and induced dendritic cell maturation. A high frequency (up to 12%) of ovalbumin (OVA)-specific CD8+ T cells and a significant antibody response were observed 2 weeks after injection of a targeted lentiviral vector encoding an OVA transgene into naive mice. This approach also protected against the growth of OVA-expressing E.G7 tumors and induced regression of established tumors. Thus, lentiviral vectors targeting dendritic cells provide a simple method of producing effective immunity and may provide an alternative route for immunization with protein antigens
Effects of the Zishen Yutai Pill compared with placebo on pregnancy outcomes among women in a fresh embryo transfer cycle: a Post Hoc subgroup analysis of a randomized controlled trial
ObjectiveTo assess whether the administration of Zishen Yutai Pill (ZYP) could improve the pregnancy outcomes in different subgroups of women undergoing fresh embryo transfer cycles.Materials and methodsThis is a post hoc analysis of a large scale, placebo-controlled, double blind, randomized clinical trial (RCT) regarding the use of ZYP during assisted reproductive technology (ART) treatment. The RCT was conducted at 19 in vitro fertilization (IVF) centers between April 2014 and June 2017. A total of 2265 women undergoing fresh embryo transfer cycles were randomly assigned in a 1:1 ratio to receive ZYP (n = 1131) or placebo (n = 1134). Post hoc logistic regression analyses were applied in this study to examine the between-group differences of ZYP and placebo on clinical pregnancy rate among different subgroups. Detailed analyses, both in intention-to-treat (ITT) and per-protocol population, were also conducted in specific subgroups with regards to rates of implantation, biochemical pregnancy, clinical pregnancy, live birth, pregnancy loss, as well as other neonatal indices.ResultsZYP showed a significantly higher clinical pregnancy rates than placebo in the ITT population. Detailed subgroup analyses were conducted in subgroup in advanced maternal age (AMA, ≥ 35 years old) and overweight/obese patients (BMI > 24), due to the clinical importance and statistical results. In these subgroups, baseline characteristics were similar between two arms (all P > 0.05). Significantly elevated clinical pregnancy rates were observed in ZYP cohort (both P < 0.05) compared with the placebo group. Results also showed that ZYP treatment resulted in significantly higher rates of implantation, biochemical pregnancy in AMA or overweight/obese patients in ITT analysis (all P < 0.05).ConclusionsThe current post hoc subgroup analysis suggested that AMA and overweight/obese women could experience clinical benefits when treated with ZYP in their fresh embryo transfer cycles. The study provides references for the use of ZYP in ART practices. However, further studies in specific subgroups should be examined in more rigorous clinical trial settings.Clinical trial registrationChictr.org.cn, ChictrTRC-14004494
Vision-based fall detection in aircraft maintenance environment with pose estimation
Fall-related injuries at the workplace account for a fair percentage of the global accident at work claims according to Health and Safety Executive (HSE). With a significant percentage of these being fatal, industrial and maintenance workshops have great potential for injuries that can be associated with slips, trips, and other types of falls, owing to their characteristic fast-paced workspaces. Typically, the short turnaround time expected for aircraft undergoing maintenance increases the risk of workers falling, and thus makes a good case for the study of more contemporary methods for the detection of work-related falls in the aircraft maintenance environment. Advanced development in human pose estimation using computer vision technology has made it possible to automate real-time detection and classification of human actions by analyzing body part motion and position relative to time. This paper attempts to combine the analysis of body silhouette bounding box with body joint position estimation to detect and categorize in real-time, human motion captured in continuous video feeds into a fall or a non-fall event. We proposed a standard wide-angle camera, installed at a diagonal ceiling position in an aircraft hangar for our visual data input, and a three-dimensional convolutional neural network with Long Short-Term Memory (LSTM) layers using a technique we referred to as Region Key point (Reg-Key) repartitioning for visual pose estimation and fall detection
Recommendations from the 2023 international evidence-based guideline for the assessment and management of polycystic ovary syndrome
STUDY QUESTION
What is the recommended assessment and management of those with polycystic ovary syndrome (PCOS), based on the best available evidence, clinical expertise, and consumer preference?
SUMMARY ANSWER
International evidence-based guidelines address prioritized questions and outcomes and include 254 recommendations and practice points, to promote consistent, evidence-based care and improve the experience and health outcomes in PCOS.
WHAT IS KNOWN ALREADY
The 2018 International PCOS Guideline was independently evaluated as high quality and integrated multidisciplinary and consumer perspectives from six continents; it is now used in 196 countries and is widely cited. It was based on best available, but generally very low to low quality, evidence. It applied robust methodological processes and addressed shared priorities. The guideline transitioned from consensus based to evidence-based diagnostic criteria and enhanced accuracy of diagnosis, whilst promoting consistency of care. However, diagnosis is still delayed, the needs of those with PCOS are not being adequately met, evidence quality was low and evidence-practice gaps persist.
STUDY DESIGN, SIZE, DURATION
The 2023 International Evidence-based Guideline update reengaged the 2018 network across professional societies and consumer organizations, with multidisciplinary experts and women with PCOS directly involved at all stages. Extensive evidence synthesis was completed. Appraisal of Guidelines for Research and Evaluation-II (AGREEII)-compliant processes were followed. The Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) framework was applied across evidence quality, feasibility, acceptability, cost, implementation and ultimately recommendation strength and diversity and inclusion were considered throughout.
PARTICIPANTS/MATERIALS, SETTING, METHODS
This summary should be read in conjunction with the full Guideline for detailed participants and methods. Governance included a six-continent international advisory and management committee, five guideline development groups, and paediatric, consumer, and translation committees. Extensive consumer engagement and guideline experts informed the update scope and priorities. Engaged international society-nominated panels included paediatrics, endocrinology, gynaecology, primary care, reproductive endocrinology, obstetrics, psychiatry, psychology, dietetics, exercise physiology, obesity care, public health and other experts, alongside consumers, project management, evidence synthesis, statisticians and translation experts. Thirty-nine professional and consumer organizations covering 71 countries engaged in the process. Twenty meetings and five face-to-face forums over 12 months addressed 58 prioritized clinical questions involving 52 systematic and 3 narrative reviews. Evidence-based recommendations were developed and approved via consensus across five guideline panels, modified based on international feedback and peer review, independently reviewed for methodological rigour, and approved by the Australian Government National Health and Medical Research Council (NHMRC).
MAIN RESULTS AND THE ROLE OF CHANCE
The evidence in the assessment and management of PCOS has generally improved in the past five years, but remains of low to moderate quality. The technical evidence report and analyses (∼6000 pages) underpins 77 evidence-based and 54 consensus recommendations, with 123 practice points. Key updates include: i) further refinement of individual diagnostic criteria, a simplified diagnostic algorithm and inclusion of anti-Müllerian hormone (AMH) levels as an alternative to ultrasound in adults only; ii) strengthening recognition of broader features of PCOS including metabolic risk factors, cardiovascular disease, sleep apnea, very high prevalence of psychological features, and high risk status for adverse outcomes during pregnancy; iii) emphasizing the poorly recognized, diverse burden of disease and the need for greater healthcare professional education, evidence-based patient information, improved models of care and shared decision making to improve patient experience, alongside greater research; iv) maintained emphasis on healthy lifestyle, emotional wellbeing and quality of life, with awareness and consideration of weight stigma; and v) emphasizing evidence-based medical therapy and cheaper and safer fertility management.
LIMITATIONS, REASONS FOR CAUTION
Overall, recommendations are strengthened and evidence is improved, but remains generally low to moderate quality. Significantly greater research is now needed in this neglected, yet common condition. Regional health system variation was considered and acknowledged, with a further process for guideline and translation resource adaptation provided.
WIDER IMPLICATIONS OF THE FINDINGS
The 2023 International Guideline for the Assessment and Management of PCOS provides clinicians and patients with clear advice on best practice, based on the best available evidence, expert multidisciplinary input and consumer preferences. Research recommendations have been generated and a comprehensive multifaceted dissemination and translation program supports the Guideline with an integrated evaluation program.
