The isolation of cellulose has found considerable applications recently due to its attractive characteristics. Cellulose from of different size classifications (425 μm-599 μm and 600 μm-849 μm) was investigated using Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), scanning electron microscopy (SEM), and energy dispersive X-ray (EDX) analyses. The crystal plane of the preferred orientation was at (020) for the most prominent peaks. The two size classifications have a strong broad peak around 3320 cm (425 μm-599 μm), and 3330 cm (600 μm-849 μm), which corresponds to a different stretching mode of O-H. High percentages of carbon (C) and oxygen (O) were noticed among the elements observed in the two size classifications. The crystallinity index (CrI) obtained for the two sizes were 61.1% for 425-599 μm, and 55.8% for 600 μm-849 μm. The 425 μm-599 μm size classification had a greater crystallinity index than the 600 μm-849 μm size classification, which indicates a stronger capacity for reinforcing. These particles were also effective as fillers in composite materials. The results revealed that cellulose possessed promising potential for device applications and capable of being used in the preparation of composite materials.

Predictors of Bilateral Disease in Low-Risk Papillary Thyroid Cancer: Histopathologic Insights and Preoperative Ultrasonography.
Ann Surg Oncol
January 2025
Department of Endocrine Surgery, Royal North Shore Hospital, University of Sydney, Sydney, Australia.
Background: With the current shift toward de-escalation of surgical management in low-risk papillary thyroid cancer (PTC), understanding predictors and the clinical significance of additional tumors in the contralateral lobe is important. This study investigated the histopathologic predictors of bilateral disease in low-risk PTC patients and the utility of preoperative ultrasonography in guiding completion thyroidectomy decisions.
Methods: Patients treated with total thyroidectomy (TT) for low-risk PTCs (< 4 cm) at the Endocrine Surgical Unit of the Royal North Shore Hospital, University of Sydney from 2013 to 2020 were identified from a prospectively maintained database.
The value of 5-HT, leptin, and NE in the classification of premature ejaculation.
Sex Med

Department of Urology, The First Affiliated Hospital of Anhui Medical University, Hefei 230032, Anhui, China.
Background: While premature ejaculation (PE) can be divided into lifelong PE (LPE), acquired PE, natural variable PE (NPE), and subjective PE (SPE), there is no objective method to classify PE.
Aim: To determine the value of serum serotonin (5-HT), leptin, and norepinephrine (NE) levels in the classification of PE.
Methods: From July 2023 to July 2024, we recruited 150 participants and divided them into 4 groups: LPE (43 cases), NPE (32 cases), SPE (35 cases), and non-PE (40 cases) groups.
Birth defects reporting and the use of dydrogesterone: a disproportionality analysis from the World Health Organization pharmacovigilance database (VigiBase).
Hum Reprod Open
January 2025
Regional Center of Pharmacovigilance, Pharmacology Department, Cochin Hospital, AP-HP.Centre-Université Paris Cité, Paris, France.
Study Question: Is there an association between dydrogesterone exposure during early pregnancy and the reporting of birth defects?
Summary Answer: This observational analysis based on global safety data showed an increased reporting of birth defects, mainly hypospadias and congenital heart defects (CHD), in pregnancies exposed to dydrogesterone, especially when comparing to progesterone.
What Is Known Already: Intravaginal administration of progesterone is the standard of care to overcome luteal phase progesterone deficiency induced by ovarian stimulation in ART. In recent years, randomized controlled clinical trials demonstrated that oral dydrogesterone was non-inferior for pregnancy rate at 12 weeks of gestation and could be an alternative to micronized vaginal progesterone.
Effectiveness of potent topical corticosteroids versus mild ones in primary care for children with moderate flare-ups of atopic dermatitis; results of a randomised controlled trial.
BMJ Open

Department Dermatology, Center of Pediatric Dermatology, Erasmus MC University Medical Center-Sophia Children's Hospital, Rotterdam, the Netherlands.
Objective: To assess the effectiveness of a potent topical corticosteroid (TCS) as an initial treatment in primary care for children with moderate flare-ups of atopic dermatitis (AD), compared to starting on a mild TCS.
Design: An observational prospective cohort study with an embedded pragmatic multicentre open-label randomised controlled trial.
Setting: A total of 53 general practices in the southwest of the Netherlands took part in the study.
The genetics of non-syndromic dentinogenesis imperfecta: a systematic review.
Eur Arch Paediatr Dent
January 2025
Dental School, The University of Western Australia, 17 Monash Avenue, Nedlands, WA, 6009, Australia.
Purpose: This systematic review aims to consolidate existing genetic and clinical data on non-syndromic dentinogenesis imperfecta (DI) to enhance understanding of its etiology.
Methods: Electronic databases were searched for genetic familial linkage studies published in English without time restrictions. Genetic familial linkage studies that reported cases of Shield's classifications: DI-II, DI-III or DD-II were included.
