Systemic lupus erythematosus is a rare, chronic autoimmune disease that can affect multiple organ systems. It is characterized by hyperactivity of B lymphocytes and autoantibodies that can cause tissue damage. Common symptoms include arthritis, skin rashes, kidney issues, and fatigue. Diagnosis requires meeting certain criteria related to constitutional symptoms, skin and joint involvement, serological markers, and organ system dysfunction. Treatment focuses on managing symptoms and preventing disease flares and organ damage using medications like corticosteroids, immunosuppressants, and hydroxychloroquine. Prognosis has improved but risks of infection and accelerated cardiovascular disease remain higher than the general population.

an overview of Lupus for journalist
Lupus has a wide spectrum of manifestation. Some mild but in most cases it has a high impact of life and quality of life
this research is made by a dental student (me) under supervision of our oral medicine specialist dr. muhassad almudhafer and this research is collected from several articles hope u like it
this my email if u would like to contact me - mnmmnz4503.mm@gmail.com
The term ‘lupus’ (Latin for ‘wolf’) was first used during the Middle Ages to describe erosive skin lesions evocative of a ‘wolf’s bite’.
Lupus is an autoimmune disease, which means that the body's natural defense system (immune system) attacks its own tissues instead of attacking foreign substances like bacteria and viruses. This causes inflammation which can causes swelling, pain, and tissue damage throughout the body.
systemic lupuse rythematosus by formation of autoantibodiesssuser45f282
Systemic lupus erythematosus is a chronic, multisystem, inflammatory, autoimmune disorder characterized by formation of autoantibodies directed against self-antigens and immune-complex formation resulting in damage to essentially any organ.
The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

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

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.

NVBDCP was launched in 2003-2004 . Vector-Borne Disease: Disease that results from an infection transmitted to humans and other animals by blood-feeding arthropods, such as mosquitoes, ticks, and fleas. Examples of vector-borne diseases include Dengue fever, West Nile Virus, Lyme disease, and malaria.
Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.

2. Introduction
Systemic Lupus erythromatosus is a rare, autoimmune based chronic
inflammatory disease of un-known aetiology.
Maybe confined to the skin or may involve multiple organs system.
Some 90% of affected patients are female.
Peak age at onset is 20 to 30 years.
Lupus is associated with morbidity and a five-fold increase in mortality
mainly because of an increased risk of premature cardiovascular
disease.
Most common cause of death are infections and Renal Failure.
3. Pathophysiology
SLE is characterized by hyper-reactivity of B
lymphocytes, hypergammaglobulinaemia,
multiple autoantibodies, circulating immune
complexes, and complement activation (low C3 ,
C4).
Autoantibodies to self antigens, increased
apoptosis and impaired clearance of apoptotic
bodies play an important role. Tissue damage is
the result of immune complex deposition as well
as direct cellular injury.

Active lupus is characterised by anaemia, leucopaenia,
lymphopaenia, and thrombocytopaenia
Proteinuria and active urinary sediment point to active
glomerulonephritis.
Rising anti-dsDNA titres and falling C3 C4 levels.
38. Prevention
All patients with lupus erythematosus
should be counseled on photoprotection,
including protecting skin from sunlight
and avoiding sun exposure during peak
hours (i.e., between 10 AM and 2 PM).
Broad-spectrum sunscreen that contains
titanium, zinc, Mexoryl (L’Oreal), or
Helioplex
(Neutrogena) should be used whenever
patients are outdoors.
Photoprotective clothing, available from
multiple vendors, is useful for limiting sun
exposure.
39. Medium-potency topical corticosteroids
Use of triamcinolone 0.1% cream (Flutex) for lesions on the
head and neck up to 2 weeks
Foam or liquid- or lotion based corticosteroids for the scalp
lesions.
Intralesional corticosteroids may cause mild discomfort,
atrophy of the skin or subcutis, or stretch marks.
Topical calcineurin inhibitors such as pimecrolimus (Elidel) or
tacrolimus (Protopic) may be used for maintenance treatment
Recurrent or refractory lesions require systemic treatment.
Treatment of Cutaneous Lupus Erythematosus
40. Antimalarials hydroxychloroquine (HCQ) are disease-
modifying agents that limit the progression of lupus.
Hydroxychloroquine at 200 mg daily for 2 weeks and then
increased to 400 mg daily.
Hydroxychloroquine exerts its effects within 2 to 3 months
of beginning treatment.
Treatment of Systemic Lupus Erythematosus
41. • Depending on end-organ involvement in SLE,
immunosuppression with systemic corticosteroids such as
prednisone at doses of 1 mg/kg/day is appropriate.
• Steroid-sparing drugs such as methotrexate , acitretin or
mycophenolate mofetil are added.
Treatment of Systemic Lupus Erythematosus cont……
42. Arthralgia can usually be managed with acetaminophen or
nonsteroidal antiinflammatory drugs (NSAIDs).
Hydroxychloroquine 200 mg twice daily can be added.
Methotrexate 7.5 to 25 mg PO once weekly with folic acid 1mg
daily .
Azathioprine (Imuran) 0.5 to 2 mg/kg with monitoring of CBC
& LFTs.
Low-dose glucocorticoids (prednisone 5–10 mg/day) may be
used as a bridge to steroid-sparing therapy and to treat
intermittent flares.
Treatment of Musculoskeletal Manifestations
43. Lupus Nephritis is one of the severe manifestation of renal
disease and Treatment should be coordinated with a
rheumatologist or nephrologist.
Class I disease no therapy.
Class II can be treated with prednisone (20 mg/day for 6 weeks
to 3 months)
Class III and IV disease treated with prednisone(1 mg/kg/day)
for 6 weeks ,maintenance of 10 to 15 mg/day.
In addition cytotoxic therapy with Cyclophosphamide 0.5 to 1
g/m BSA monthly for 6 months and tapered to every 3 months
Class V disease can be treated with prednisone alone, similar to
class II disease
Treatment of Renal Manifestations
44. Neuropsychiatric Symptoms can range from mild to severe
headache, aseptic meningitis, neuropathy, myelopathy,
cognitive dysfunction, seizures, cerebritis, and stroke.
For seizures, antiepileptic therapy is used.
Lupus cerebritis and transverse myelitis are two of the more
serious manifestations that need to be treated emergently with
aggressive immunosuppression.
Treatment includes high-dose corticosteroids and
cyclophosphamide, similar to treatment for lupus nephritis.
Treatment of Nervous System Manifestations
46. • Steroids, hydroxychloroquine, and azathioprine can be
continued during pregnancy.
• Cyclophosphamide, methotrexate, and mycophenolate
should be discontinued 3 to 6 months before conception.
• Cyclophosphamide therapy carries the risk of age
dependent ovarian failure.
• Intrauterine contraceptive devices should be avoided.
• Oestrogen-containing contraceptives should be avoided
with APS
