The development of a normal retina and a retina with an early one-side occlusion in consequence of a cataract or a wall-eye was studied. Autoradiographically and with the help of a scanning cytophotometry method a normal maturing of a retina was shown to be finished in fourteen days of postnatal development without any significant changes. The degenerative changes of ganglion-cells ensuing the maturity of retina were discovered during the experiment. The depression of a protein metabolism of neurons in the deprived eye passes ahead the marked morphological changes. The gangliocytes of the intact eye don't differ much from the normal ones.

Effectiveness of Remote Patient Monitoring Equipped With an Early Warning System in Tertiary Care Hospital Wards: Retrospective Cohort Study.
J Med Internet Res
January 2025
Hospital Administration, Ramaiah Memorial Hospital, Bengaluru, Karnataka, India.
Background: Monitoring vital signs in hospitalized patients is crucial for evaluating their clinical condition. While early warning scores like the modified early warning score (MEWS) are typically calculated 3 to 4 times daily through spot checks, they might not promptly identify early deterioration. Leveraging technologies that provide continuous monitoring of vital signs, combined with an early warning system, has the potential to identify clinical deterioration sooner.

Background: Patients with human epidermal growth factor receptor 2 (HER2)-positive early breast cancer with residual invasive disease after neoadjuvant systemic therapy have a high risk of recurrence and death. The primary analysis of KATHERINE, a phase 3, open-label trial, showed that the risk of invasive breast cancer or death was 50% lower with adjuvant trastuzumab emtansine (T-DM1) than with trastuzumab alone.
Methods: We randomly assigned patients with HER2-positive early breast cancer with residual invasive disease in the breast or axilla after neoadjuvant systemic treatment with taxane-based chemotherapy and trastuzumab to receive T-DM1 or trastuzumab for 14 cycles.
Fracture Prevention with Infrequent Zoledronate in Women 50 to 60 Years of Age.
N Engl J Med
January 2025
From the Department of Medicine, University of Auckland, Auckland, New Zealand (M.J.B., Z.N., A.M., C.G., V.P., B.M., A.G., I.R.R., G.G., A.H.); the Department of Psychology, Stanford University, Stanford, CA (C.G.); and the Department of Radiology, Starship Hospital, Auckland, New Zealand (S.B.).
Background: Zoledronate prevents fractures in older women when administered every 12 to 18 months, but its effects on bone density and bone turnover persist beyond 5 years. Whether infrequent zoledronate administration would prevent vertebral fractures in early postmenopausal women is unknown.
Methods: We conducted a 10-year, prospective, double-blind, randomized, placebo-controlled trial involving early postmenopausal women (50 to 60 years of age) with bone mineral density T scores lower than 0 and higher than -2.
