Anti-VEGF injections have been effective in treating age-related macular degeneration but can cause side effects from frequent injections. A clinical trial studied using low-dose radiation therapy combined with anti-VEGF injections in 230 patients over 3 years. Results showed the radiation therapy group had a reduction in needed injections of 26% after 2 years while maintaining comparable vision. Some patients developed localized microvascular changes from the radiation but vision was not significantly affected. Radiation exposure was low risk and radiation retinopathy can now be treated with anti-VEGF drugs.

Role of Topical Tranexamic Acid in Hemostasis of Locally Advanced Basal Cell ...J W
Tranexamic acid (TXA) is a synthetic derivative of
the amino acid, lysine. Conventionally used orally or
intravenously, topical administration of TXA has the
ability to reduce bleeding with minimal systemic
absorption and, in turn, reduce the risk of systemic
side effects. Previous clinical trials found that topical
TXA reduces blood loss in cardiac, orthopedic, and
otolaryngologic surgery.1 However, the hemostatic
role of topical TXA for the skin has not been fully
established. We describe a case of an elderly female
with locally advanced basal cell carcinoma (BCC) of
the scalp that was managed conservatively. The
bleeding from the tumor was reduced with the aid
of topical TXA.
My Works is a Common task for the majority of Security Forces Officers Club/administrators include Food processing, Managing Staff Work Schedule, letter writing and email inquiries, keeping diaries, arranging meetings appointments discrepancies for accounting, reimbursement, and record-keeping.

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection

Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

2. In Treatment of age related Macular
Degeneration Anti VEGF injections played
pivotal role since their discovery in mid
2000s.
Earlier treatments merely slowed the on going
visual loss, whereas with Anti VEGF injections,
one could expect visual improvement.
4. Clue taken from oncology
Uses a low energy X ray source
X ray is collimated to a narrow beam
I. Enables rapid dose fall off
II. Precise targeting
III. Minimum radiation scatter
During treatment, a vaccum coupled contact
are used to stabilise globe
Real time monitoring done
5. One year clinical trial, double blind
prospective study.
230 patients of neovascular wet AMD * 3
years, already receiving anti VEGF injections.
All received an initial dose of ranibizumab
and were randomised to receive 16Gy
radiation.
Single 26 min radiotherapy treatment was
given.
Patients were evaluated monthly *12months
6. After 1 year- Injections were reduced by
1/3rd with comparable visual acuity. Then
patients were returned to their original
drug schedule
After 2 years- Safety and efficacy data
were collected. Injections were reduced by
26%. Vision changes were similar.
After 3 years- Only safety data were
collected. No significant difference visual
outcome.
Radiation retinopathy- 33/122
18 regressed
14% wet amd
8% dry amd
7. Radiations are anti-angiogenic, anti-
inflammatory, anti-proliferative.
Doesn’t treat scar tissue.
Eyes with actively proliferative leisons,
producing fluid leakage are more likely to
respond.
Fibers grow centrifugaly, so fibers remain
proliferative at edges.
Lesions with diameter <4mm, and/or macular
volume >7.4mm^3 reqired fewer injections.
8. Radiation radiotherapy rare below 30 Gy.
Develops within 7-36 months.
Long term s/e like radiation radiotherapy and
microvasculopathy.
Simultaneous clinical trial of s/e was
conducted.
9. Over 3 yrs, 30 % patients receiving
radiations developed small localised
microvascular abnormality.
It didn’t modify visual outcome
significantly.
Few regressed themselves over time.
Radiation exposure is 10% of CT Head &
same as dental radiography.
Fractioning total dose reduces the risk
Radiation retinopathy is now treatable by
Anti VEGF drugs.
10. Most tolerated the treatment well and
were satisfied.
Decreasing injections was most imp
cause.
