Urinary tract infections during pregnancy can cause complications if left untreated. There are several types of urinary tract infections that can occur, including asymptomatic bacteriuria, acute cystitis, and acute pyelonephritis. Left untreated, these infections have been linked to adverse outcomes like preterm birth and low birth weight. Proper diagnosis involves urine testing and culture. Treatment involves antibiotics, hydration, and pain medications when needed. Screening is important for detecting asymptomatic infections which can later cause issues if not treated.

Ectopic Pregnancy - Obstetrical & Gynaecological NursingJaice Mary Joy
In ectopic pregnancy, implantation occupies at a site other than the endometrium. Ectopic pregnancies are responsible for approximately 10 percent of all maternal mortality. The prognosis for future reproduction is poor. Only one half of women having an ectopic pregnancy are eventually delivered of a liveborn infant. Various factors contribute to ectopic pregnancies, the most common being infection. Unlike intrauterine spontaneous abortions, genetic factors are not paramount in the etiology of ectopic pregnancy.

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
Tom Selleck Health: A Comprehensive Look at the Iconic Actor’s Wellness Journeygreendigital
Tom Selleck, an enduring figure in Hollywood. has captivated audiences for decades with his rugged charm, iconic moustache. and memorable roles in television and film. From his breakout role as Thomas Magnum in Magnum P.I. to his current portrayal of Frank Reagan in Blue Bloods. Selleck's career has spanned over 50 years. But beyond his professional achievements. fans have often been curious about Tom Selleck Health. especially as he has aged in the public eye.
Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

6. Epidemiology
UTIs in women: 14 times more frequent than
in men.
1. The urethra is shorter
2. lower 1/3 of the urethra is continually
contaminated with pathogens from the vagina and
the rectum
3. Women tend not to empty their bladders as
completely as men do
4. Urogenital system is exposed to bacteria during
intercourse
Aboubakr Elnashar
7. Increase the frequency (UTIs) in pregnant
women.
1. Difficult hygiene due to a distended pregnant
belly
2. Immunocompromised

smooth muscle relaxation}
urinary retention {weight of the enlarging uterus}
Loss of ureteral tone combined with increased
urinary tract volume: urinary stasis: dilatation of the
ureters, renal pelvis, and calyces.

9. 4. Glycosuria and aminoaciduria
Glycosuria {impaired resorption by the collecting
tubule and loop of Henle of the 5% of the filtered
glucose, which escapes proximal convoluted
tubular resorption}.
Selective aminoaciduria {unknown} although its presence has been postulated to
affect the adherence of Escherichia coli to the urothelium.

10. Asymptomatic bacteriuria
Risk factors
5-fold poor patients

Other risk factors
DM
Neurogenic bladder retention
History of vesicoureteral reflux
previous renal transplantation
history of previous UTIs
multiple pregnancy

Aboubakr Elnashar
12. Pathophysiology
Infections result from ascending colonization of
the urinary tract, primarily by existing
vaginal,
perineal, and
fecal flora.
Aboubakr Elnashar
13. Etiology
Infection
E coli : most common cause of UTI, 80-90%
originates from fecal flora colonizing the periurethral
area: ascending infection.
Other pathogens:
Klebsiella pneumoniae (5%)
Proteus mirabilis (5%)
Enterobacter species (3%)
Staphylococcus saprophyticus (2%)
Group B beta-hemolytic Streptococcus (GBS; 1%)
Proteus species (2%)

15. GBS colonization
Intrapartum transmission: neonatal GBS
pneumonia, meningitis, sepsis, and death.
Guidelines
universal vaginal and rectal screening in all pregnant
women at 35-37 W rather than treatment based on
risk factors.

16. Preeclampsia
predisposed to UTI.
UTI
16.2% in normotensive
27.3% in mild PET
35.9% in severe PET
{underlying renal damage weakens patients’
systemic defense mechanisms against ascending
infection}.
Aboubakr Elnashar
21. Other complications:
1. Perinephric cellulitis and abscess, Septic
shock (rare)
2. Renal dysfunction (usually transient, but as many
as 25% of pregnant women with pyelonephritis
have a decreased glomerular filtration rate)
3. Hematologic dysfunction (common but seldom of
clinical importance)
4. Pulmonary injury: 2% of women with severe
pyelonephritis
during pregnancy have evidence of pulmonary injury due to systemic inflammatory response syndrome
and respiratory insufficiency. Endotoxins that alter alveolar-capillary membrane permeability are
produced; subsequently, pulmonary edema and acute respiratory distress syndrome develop.

infection that lead to hypoperfusion of the placenta}
6. PTL: increased infant morbidity and mortality
Aboubakr Elnashar
23. Diagnosis
I. History
Cystitis
1. Dysuria
most significant symptom
2. Other symptoms:
Frequency
Urgency
suprapubic pain
hematuria in the absence of systemic symptoms.
The usual complaints of increased frequency, nocturia, and suprapubic pressure
are not particularly helpful, {most pregnant women experience these as a
result of increased pressure from the growing uterus, expanding blood
volume, increased glomerular filtration rate, and increased renal blood
flow.}
Aboubakr Elnashar
24. Pyelonephritis:
1. Fever (>38°C)
2. Shaking chills
3. Anorexia, nausea, and vomiting.
4. Right-side flank pain is more common than left-
side or bilateral flank pain.
5. Lower UTI symptoms: common but not
universal.
6. ±hypothermia (as low as 34°C).
Aboubakr Elnashar
25. II. Physical Examination
Pelvic examination:
recommended in all symptomatic patients
(with the exception 3rd trimester patients with
bleeding) to rule out vaginitis or cervicitis
Aboubakr Elnashar
26. Asymptomatic bacteriuria
No physical findings are typically present.
Symptoms may arise intermittently, only to be overlooked because of
lack of persistence or severity.
Cystitis
Tenderness.
Aboubakr Elnashar
27. Pyelonephritis
1. Fever (usually >38°C) an ill appearance.
2. Flank tenderness
on the right side in more than half of patients,
bilaterally in one fourth
on the left side in one fourth.
3. Assessment of the FHR
{maternal fever} FHR: elevated to more than 160
beats/min.

30. > 1 organism in a culture: contaminated
specimen.
The specimen should be sent for evaluation as soon as possible
{Specimens that are allowed to sit at room temperature may have falsely
elevated colony counts}. Refrigerate the specimen at 4°C if it cannot be
transported immediately.
Aboubakr Elnashar
31. Urine culture
Standard method for evaluating for UTI during
pregnancy.
Indications :
Recurrent UTI
Pyelonephritis
Failure to respond to initial treatment
History of recent instrumentation
Hospital admission
Aboubakr Elnashar
32. Positive culture
Two consecutive voided specimens with isolation of the
same bacterial strain, at a colony count of 100,000 colony-
forming units (CFUs) per milliliter or higher OR
A single catheterized specimen yielding a colony count of at
least 100 CFU/mL
Contamination
Counts lower than 100,000 CFU/mL, with 2 or more
organisms
Patients with pyelonephritis often have white blood cell
(WBC) casts.
Culture results can be used to identify specific organisms
and antibiotic sensitivities
Cultures yielding significant growths of mixed organisms
should prompt a search for underlying renal calculi.
Aboubakr Elnashar
33. Urinalysis
Positive results for nitrites, leukocyte esterase,
WBCs, RBCs, and protein: suggest UTI.
Bacteria found in the specimen can help with the
diagnosis.
Urinalysis:
Specificity (ability to identify negtive results): 97-100%
Sensitivity (ability to identify positive results).: 25-67%=false-positive rate is very high
1-2 bacteria in an unspun catheterized specimen
or >20 bacteria /HPF in spun urine correlate closely
with bacterial colony counts >100,000 CFU/mL on a
urine culture. Aboubakr Elnashar
34. Dipstick testing for nitrites & leukocyte esterase
in the evaluation of asymptomatic bacteriuria:
Sensitivity: 50% to 92% and
Specificity: 86% to 97%.
In the evaluation of symptomatic:
useful and inexpensive.
leukocyte esterase test may be unreliable in
patients with low-level pyuria (5-20 WBCs/HPF).
The addition of protein and blood increases the
sensitivity and specificity of the test in the
evaluation of UTI.
Aboubakr Elnashar
35. Nitrite dipstick testing
may be a reasonable and cost-effective screening
strategy for women who otherwise may not
undergo screening for bacteriuria, as is often the
case in developing countries.
Aboubakr Elnashar
36. Urine cytology:
useful adjunct in detecting UUTIs.
Clumping WBCs and WBC casts:
pyelonephritis.
RBC casts:
acute glomerulonephritis
Oval fat bodies and fatty casts:
Membranous glomerulonephritis.
Renal involvement:
proteinuria.
Nephrotic syndrome:
high proteinuria (>3.5 g/24 h), edema, hypercholesterolemia, and
hypoalbuminemia;
can be confused with preeclampsia.
Aboubakr Elnashar
37. Other tests
An antistreptolysin-O (ASO) titer:
greater than 200 Todd units: recent group A streptococcal
infection; however, as many as 20% of patients with acute
glomerulonephritis have ASO titers within the reference
range.
The sulfosalicylic acid (SSA) test:
measures urine turbidity when a small amount of aspirin is
added to the urine specimen.
A finding of +2 to +4 suggests bacteriuria.
Aboubakr Elnashar
38. Renal Ultrasonography and limited
Intravenous Pyelography (IVP)
Indications
1. An anatomic abnormality or renal disease is
suspected
2. Patients with suspected pyelonephritis who are
not responsive to appropriate antibiotic therapy
after 48-72 h
3. Recurrent UTI or symptoms that suggest
nephrolithiasis, if the benefits of a definitive
diagnosis outweigh the minor risk of radiation
Aboubakr Elnashar
39. Renal US is often performed initially, but the
findings are often inconclusive.
A limited IVP (kidneys-ureters-bladder [KUB] with
a 30-min shot after contrast injection) can be
helpful in delineating the site of the obstruction.
Aboubakr Elnashar
40. The total dosage of ionizing radiation should not
exceed 3-5 cGy during the course of pregnancy.
Of particular concern is radiation delivered during
1st trimester, during organogenesis (especially days
11-56).
A limited IVP can deliver 0.4-1 cGy.
Radiation doses >5 cGy: increased likelihood of
benign and malignant tumors in the child after birth.
No patient should receive more than 10-14 cGy.
Centigray: a unit of absorbed radiation dose equal
to one hundredth of a gray, or 1 rad.
Aboubakr Elnashar
41. Urolithiasis
unique problem in pregnant women.
Diagnosis:
Pyelonephritis have many symptoms in common
(eg, hematuria, flank pain, shaking chills, anorexia).
usually not associated with fever, except in
patients with concomitant pyelonephritis.
Confusion about the diagnosis of urolithiasis,
pyelonephritis, or both is an indication for obtaining
imaging studies.
Aboubakr Elnashar
42. Treatment
initially conservative
{50-67% diagnosed during pregnancy pass
spontaneously}
Antibiotic
Hydration
Analgesics
(usually narcotics, which are class C agents in
pregnancy).
Anti-inflammatory {oligohydramnios, premature
closure of the patent ductus arteriosus, or both}
should be avoided if possible.
Aboubakr Elnashar
43. If ultrasonography reveals a stone, ultrasound-
guided cystoscopic passage of a ureteral stent may
relieve ureteral colic.
In some cases (eg, pyonephrosis with an
obstructing stone), percutaneous nephrostomy can
be useful.
Cystoscopic extraction of a distal ureteral stone
(with fluoroscopic guidance) should be used
sparingly because of the risk of ionizing radiation to
the fetus.
Aboubakr Elnashar
44. Treatment
Bacteriuria and cystitis
1. Administration of appropriate antibiotics
2. Administration of fluid if the patient is
dehydrated
3. Admission if any indication of complicated UTI
exists
Aboubakr Elnashar
45. Behavioral methods
To ensure good hygiene and reduce bacterial contamination of the urethral
meatus: preventing inadequate treatment and recurrent infection.
1. Avoid baths
2. Wipe front-to-back after urinating or defecating
3. Wash hands before using the toilet
4. Use washcloths to clean the perineum
5. Use liquid soap to prevent colonization from bar soap
6. Clean the urethral meatus first when bathing
7. Changes in coital patterns (eg, position, frequency, postcoital antibiotics) can
offset recurrence in at-risk individuals.
Several non-pharmacological manoeuvres may help prevent recurrent infec-
tion in those women troubled by UTIs in pregnancy. These include:
Increasing fluid intake. This ensures frequent voiding and a high-volume dilute
urine, all of which reduce the risk of symptomatic infection Emptying the bladder
following sexual intercourse. This 'washes away' organisms massaged up the
urethra from the perineum into the bladder during coitus, before they have a
chance to replicate in urine within the bladder
Double voiding (to ensure no residual urine is left in the bladder following
micturition)
The perineum should be cleaned from 'front to back' following defaecation to
minimise the risk of bowel organisms colonising the urethra.
Aboubakr Elnashar
47. Antibiotic therapy
Oral antibiotics are the treatment of choice for
asymptomatic bacteriuria and cystitis.

Nitrofurantoin 100 mg four times daily for 21 days
Suppression for bacterial persistence or
recurrence
Nitrofurantoin 100 mg at bedtime for remainder of
pregnancy

50. The resistance of E coli to ampicillin and
amoxicillin is 20-40%; accordingly, these agents
are no longer considered optimal for treatment of
UTIs caused by this organism.
Fosfomycin, a phosphonic acid derivative, is useful in the treatment of
uncomplicated UTIs caused by susceptible strains of E
coli and Enterococcusspecies.
Fosfomycin is a category B agent in pregnancy (ie, fetal risk is not
confirmed by human studies but has been shown in some animal
studies).
Aboubakr Elnashar
51. Although 1-, 3-, and 7-day antibiotic courses have
been evaluated, 10-14 days of treatment is usually
recommended to eradicate the offending bacteria.
Treatment for 3 days is sufficient for asymptomatic
bacteriuria. Regular urine cultures should be taken
following treatment to ensure eradication of the
organism. About 15% of women will have recurrent
bacteriuria during their pregnancy and require a
second course of antibiotics.
Antibiotics should be continued for 5-7 days in
cystitis
Cephalexin, trimethoprim-sulfamethoxazole, and
amoxicillin single dose is as effective as a 3- to 7-
day course of therapy, but the cure rate is only
70%. Aboubakr Elnashar
52. A test-for-cure urine culture should show negative
findings 1-2 w after therapy.
A nonnegative culture result is an indication for a
10- to 14-day course of a different antibiotic,
followed by suppressive therapy
(eg, nitrofurantoin 50 mg at bedtime) until 6 w
postpartum.
Aboubakr Elnashar
53. Acute Pyelonephritis
Hospitalization
Investigations and monitoring
Urine and blood cultures
CBC, serum creatinine, and electrolytes
Monitor vital signs frequently, urinary output,
consider indwelling catheter
Establish urinary output to 50 mL/hr with IVF
Chest radiograph if there is dyspnea or
tachypnea
Aboubakr Elnashar
54. IV antibiotics
IV fluids
with caution. Patients with pyelonephritis can
become dehydrated {nausea and vomiting} and
need IV hydration. However, they are at high risk
for the development of pulmonary edema and
ARDS
Fever:
antipyretics (preferably, acetaminophen)
Nausea and vomiting:
antiemetics.
Most antiemetics can be used for adverse effects caused by antibiotics,
but doxylamine, Emetrol (Wellspring, Sarasota, FL; pregnancy class A),
dimenhydrinate, and metoclopramide (pregnancy class B) are preferred.
Aboubakr Elnashar
55. Follow up
Repeat hematology and chemistry studies in 48 h
Change to oral antimicrobials when afebrile
Discharge when afebrile 24 h, consider antibiotic
for 7 to 10 days
Repeat urine culture 1 to 2 weeks after antibiotic
completed
Aboubakr Elnashar
56. Risk of PTL must be evaluated and treated early in
the course of admission.
{Pyelonephritis places the patient at risk for
spontaneous abortion in early pregnancy and for
preterm labor after 24 w}.
Aboubakr Elnashar
57. Antibiotic selection
IV administration of cephalosporins or gentamicin.
Antibiotic selection should be based on urine
culture sensitivities, if known. Often, therapy must be
initiated on an empirical basis, before culture results
are available.
Institution-specific drug resistances should also be
considered before a treatment antibiotic is chosen.
E coli infection resistance to
Ampicillin: 28-39%.
Trimethoprim-sulfamethoxazole: 31%
First-generation cephalosporins: 9-19%.
Aboubakr Elnashar
58. Some antibiotics should not be used during
pregnancy:
Tetracyclines (adverse effects on fetal teeth and
bones and congenital defects)
Chloramphenicol (gray syndrome)
Trimethoprim in the first trimester (facial defects
and cardiac abnormalities)
Sulfonamides (hemolytic anemia in mothers with
glucose-6-phosphate dehydrogenase [G6PD]

59. Fluoroquinolones:
are contraindicated in pregnancy.
Although in utero exposure is not an indication for
termination, fetal exposure to fluoroquinolones has
been associated with myelomeningocele,
hydrocephaly, hypospadias, maldescended testes,
inguinal hernia, bilateral hip dysplasia, and atrial
septal defects. That the anomalies seem not to
follow a particular pattern may be reassuring;
however, a causal relation cannot be excluded.

60. Nitrofurantoin
safe and effective; however, poor tissue penetration
has limited its use in pyelonephritis.
In the past, nitrofurantoin was completely avoided
in the third trimester because of hemolytic effects
on the newborn. Currently, restriction of this agent
is limited to the last several weeks of pregnancy.
Use during this period can cause hemolytic anemia
in the fetus or neonate as a consequence of their
immature erythrocyte enzyme systems (glutathione
instability).
Nitrofurantoin is also safe and effective for once-
daily prophylactic therapy during pregnancy.

62. Surgical treatment
Rarely indicated, unless one of the pathologic
causes listed in the differential diagnoses is
suspected.
In patients with urethral or bladder diverticulum,
bladder stones, urethral syndrome, lower urinary
tract trauma, interstitial cystitis, or bladder cancer,
cystoscopy may aid in establishing the diagnosis.
A retrograde stent or a percutaneous
nephrostomy tube should be placed to relieve
ureteral colic or decompress an obstructed infected
collecting system. More invasive procedures, such
as ureteroscopic stone extraction,are rarely
indicated. Aboubakr Elnashar
63. Extracorporeal shock wave lithotripsy (ESWL) is
contraindicated in pregnancy.
In the rare patient for whom invasive surgical
therapy is indicated, the operation should be
planned for the second trimester. Surgical
intervention during the first trimester is associated
with miscarriage; surgery in the third trimester is
associated with preterm labor. Urgent surgical
intervention in the third trimester should coincide
with delivery of the fetus.

64. Conclusion
Urinary tract infection is more common in
pregnancy.
Asymptomatic bacteriuria should be treated
because there is a significant risk of acute
pyelonephritis.
Acute pyelonephritis increases the risk of premature
labour.
Acute pyelonephritis should be managed in hospital
with i.v, antibiotics.
Once antibiotic treatment has rendered the urine
sterile, regular MSU specimens are necessary to
exclude reinfection.

65. Amoxycillin and cephalosporins are appropriate
antibiotics for the treatment and prevention of UTI in
pregnancy.
Gentamicin may be required for severe or resistant
infections.
Investigations in cases of pyrexia and suspected
acute pyelonephritis should include blood cultures, a
full blood count, renal function and a renal US.
