R3 Stem Cells and Kidney Repair A New Horizon in Nephrology.pptxR3 Stem Cell
R3 Stem Cells and Kidney Repair: A New Horizon in Nephrology" explores groundbreaking advancements in the use of R3 stem cells for kidney disease treatment. This insightful piece delves into the potential of these cells to regenerate damaged kidney tissue, offering new hope for patients and reshaping the future of nephrology.
Defecation
Normal defecation begins with movement in the left colon, moving stool toward the anus. When stool reaches the rectum, the distention causes relaxation of the internal sphincter and an awareness of the need to defecate. At the time of defecation, the external sphincter relaxes, and abdominal muscles contract, increasing intrarectal pressure and forcing the stool out
The Valsalva maneuver exerts pressure to expel faeces through a voluntary contraction of the abdominal muscles while maintaining forced expiration against a closed airway. Patients with cardiovascular disease, glaucoma, increased intracranial pressure, or a new surgical wound are at greater risk for cardiac dysrhythmias and elevated blood pressure with the Valsalva maneuver and need to avoid straining to pass the stool.
Normal defecation is painless, resulting in passage of soft, formed stool
CONSTIPATION
Constipation is a symptom, not a disease. Improper diet, reduced fluid intake, lack of exercise, and certain medications can cause constipation. For example, patients receiving opiates for pain after surgery often require a stool softener or laxative to prevent constipation. The signs of constipation include infrequent bowel movements (less than every 3 days), difficulty passing stools, excessive straining, inability to defecate at will, and hard feaces
IMPACTION
Fecal impaction results from unrelieved constipation. It is a collection of hardened feces wedged in the rectum that a person cannot expel. In cases of severe impaction the mass extends up into the sigmoid colon.
DIARRHEA
Diarrhea is an increase in the number of stools and the passage of liquid, unformed feces. It is associated with disorders affecting digestion, absorption, and secretion in the GI tract. Intestinal contents pass through the small and large intestine too quickly to allow for the usual absorption of fluid and nutrients. Irritation within the colon results in increased mucus secretion. As a result, feces become watery, and the patient is unable to control the urge to defecate. Normally an anal bag is safe and effective in long-term treatment of patients with fecal incontinence at home, in hospice, or in the hospital. Fecal incontinence is expensive and a potentially dangerous condition in terms of contamination and risk of skin ulceration
HEMORRHOIDS
Hemorrhoids are dilated, engorged veins in the lining of the rectum. They are either external or internal.
FLATULENCE
As gas accumulates in the lumen of the intestines, the bowel wall stretches and distends (flatulence). It is a common cause of abdominal fullness, pain, and cramping. Normally intestinal gas escapes through the mouth (belching) or the anus (passing of flatus)
FECAL INCONTINENCE
Fecal incontinence is the inability to control passage of feces and gas from the anus. Incontinence harms a patient’s body image

Medical Technology Tackles New Health Care Demand - Research Report - March 2...pchutichetpong
M Capital Group (“MCG”) predicts that with, against, despite, and even without the global pandemic, the medical technology (MedTech) industry shows signs of continuous healthy growth, driven by smaller, faster, and cheaper devices, growing demand for home-based applications, technological innovation, strategic acquisitions, investments, and SPAC listings. MCG predicts that this should reflects itself in annual growth of over 6%, well beyond 2028.
According to Chris Mouchabhani, Managing Partner at M Capital Group, “Despite all economic scenarios that one may consider, beyond overall economic shocks, medical technology should remain one of the most promising and robust sectors over the short to medium term and well beyond 2028.”
There is a movement towards home-based care for the elderly, next generation scanning and MRI devices, wearable technology, artificial intelligence incorporation, and online connectivity. Experts also see a focus on predictive, preventive, personalized, participatory, and precision medicine, with rising levels of integration of home care and technological innovation.
The average cost of treatment has been rising across the board, creating additional financial burdens to governments, healthcare providers and insurance companies. According to MCG, cost-per-inpatient-stay in the United States alone rose on average annually by over 13% between 2014 to 2021, leading MedTech to focus research efforts on optimized medical equipment at lower price points, whilst emphasizing portability and ease of use. Namely, 46% of the 1,008 medical technology companies in the 2021 MedTech Innovator (“MTI”) database are focusing on prevention, wellness, detection, or diagnosis, signaling a clear push for preventive care to also tackle costs.
In addition, there has also been a lasting impact on consumer and medical demand for home care, supported by the pandemic. Lockdowns, closure of care facilities, and healthcare systems subjected to capacity pressure, accelerated demand away from traditional inpatient care. Now, outpatient care solutions are driving industry production, with nearly 70% of recent diagnostics start-up companies producing products in areas such as ambulatory clinics, at-home care, and self-administered diagnostics.

Antibiotic Stewardship by Anushri Srivastava.pptxAnushriSrivastav
Stewardship is the act of taking good care of something.
Antimicrobial stewardship is a coordinated program that promotes the appropriate use of antimicrobials (including antibiotics), improves patient outcomes, reduces microbial resistance, and decreases the spread of infections caused by multidrug-resistant organisms.
WHO launched the Global Antimicrobial Resistance and Use Surveillance System (GLASS) in 2015 to fill knowledge gaps and inform strategies at all levels.
ACCORDING TO apic.org,
Antimicrobial stewardship is a coordinated program that promotes the appropriate use of antimicrobials (including antibiotics), improves patient outcomes, reduces microbial resistance, and decreases the spread of infections caused by multidrug-resistant organisms.
ACCORDING TO pewtrusts.org,
Antibiotic stewardship refers to efforts in doctors’ offices, hospitals, long term care facilities, and other health care settings to ensure that antibiotics are used only when necessary and appropriate
According to WHO,
Antimicrobial stewardship is a systematic approach to educate and support health care professionals to follow evidence-based guidelines for prescribing and administering antimicrobials
In 1996, John McGowan and Dale Gerding first applied the term antimicrobial stewardship, where they suggested a causal association between antimicrobial agent use and resistance. They also focused on the urgency of large-scale controlled trials of antimicrobial-use regulation employing sophisticated epidemiologic methods, molecular typing, and precise resistance mechanism analysis.
Antimicrobial Stewardship(AMS) refers to the optimal selection, dosing, and duration of antimicrobial treatment resulting in the best clinical outcome with minimal side effects to the patients and minimal impact on subsequent resistance.
According to the 2019 report, in the US, more than 2.8 million antibiotic-resistant infections occur each year, and more than 35000 people die. In addition to this, it also mentioned that 223,900 cases of Clostridoides difficile occurred in 2017, of which 12800 people died. The report did not include viruses or parasites

2. Introduction
• Prevention of dental disease is based on the
knowledge of the disease epidemiology.
• So to study these problems we need to develop
a suitable, practical method for recording and
classifying the occurrence and severity of the
disease.
• Dental index can be consider as the main tool
to find out the incidence, prevalence, and
severity of disease
• Dental indices provide quantitative method to
measure, score, and analyze dental condition in
individual and group
3. Home work
• The measurement of dental disease is easier
than the measurement of any other forms of
disease?
• Why we measure diseases in a quantitative
terms, why?
4. index
• A numerical value of a clinical disease or condition
based on determined criteria, under specified
conditions, with definite upper and lower limits,
designed to facilitate compression among population
examined by the same criteria and method.
• An index is an indicator or measure of something.
5. Uses of dental index
1. Assess prevalence and incidence of oral
disease.
2. Provide baseline data for comparison in
epidemiological studies.
3. Study oral health status of individual and
population for planning DHC.
4. In clinical trials to define specific problem.
5. Evaluation of oral health services and
preventive programs.
6. Properties of an ideal index
Clarity, simplicity and objectivity
• The examiner should be able to carry the rules
of the index in his mind.
• Easy to apply with no loss of time.
• Criteria should be clear and unambiguous.
7. Properties of an ideal index
Validity
• Must measure what is intended to measure.
• Accurately reflects the extent to which the disease
present, for example:
The higher the score the more severe the disease.
8. Properties of an ideal index
Reliability and reproducibility
• The index most give the same results each time
it is applied.
Means : if the same or different researchers
examined the same patient with the same
condition multiple times, each time results
would be the same.
9. Properties of an ideal index
Quantifiability
The index should be amenable to statistical
analysis, so that the status of disease can be
expressed by a number corresponds to a relative
position on a scale from zero to upper limit.
10. Properties of an ideal index
Sensitivity
The index should be able to detect reasonable
small shifts in either direction in the group
condition.
11. Properties of an ideal index
Acceptability
The use of index should not be painful or
demeaning to the subject and should be
universally acceptable.
12. Properties of an ideal index
Cost and material
Require minimal equipment and
expenditure.
13. Classification of indices
Based on:
• Direction in which their scores can fluctuate.
reversible GI irreversible DMF
• The extent to which areas of oral cavity are measured.
full mouth index RUSSLE PI simplified index G&V OHI-S
• The entity which they measure.
disease D symptoms GBI treatment F
• Special categories.
simple PI cumulative DMF
14. Examples of dental indices:
DMFT - Caries activity
RCI - Root caries
GBI - Gingival bleeding
CPITN - Community periodontal index of
treatment needs
DFI - Dental fluorosis.
15. Indices used for assessment of
dental caries
Decayed-Missing-
Filled index (DMF)
16. DECAYED-MISSING-FILLED INDEX
• D component describe decay.
• M component describe missing due to caries.
• F component describe filling due to caries.
This index developed by klein et al (1938 ) and modified by
WHO.
Coronal caries of permanent teeth only.
Gives the sum of an individual’s decayed, missing, filled
permanent teeth or surface.
17. DMF
DMF Teeth index (DMFT)
DMF Surface index
(DMFS)
It is used to measure
the prevalence of
dental caries
It is used to measure
the severity of dental
caries
18. Principles and rules in recording DMF index
1. No tooth or surface must be counted more than once.
2. Tooth with restoration on one surface and caries on the
other, should record as decay.
3. A tooth considered to be erupted when just the tip of
occlusal surface or incisor edge is exposed.
4. A tooth is considered to be present even if only the roots
are left.
5. Primary tooth retained with the permanent successor
erupted, the permanent tooth evaluated.
6. Excluded teeth:3rd molar (klien et al), supernumerary
teeth.
7. Examiner use only dental mirror and explorer.
19. WHO modification of DMF index
1. 3rd molar are included.
2. Teeth with temporary restorations are considered as
decayed (D).
3. Initial caries is not regarded as decayed.
20. Calculation of DMFT/DMFS
for individual: DMF= D+M+F
for population: mean DMF =
Total DMF
____________________________________
Total number of subjects examined
Maximum score DMFT = 28 0r 32
Maximum score DMFS = 128 or 148
21. Caries indices for primary dentition
def index
Grubbel (1944) as an equivalent index to DMF
for measuring caries in primary dentition.
deft and defs
Basic principles same as that for DMF index.
d= decay
e= extracted/indicated for extraction
f= filled
22. dmf index
This index used in children before ages of
exfoliation.
Include dmft and dmfs.
df index
Missing teeth are ignored because of wide
variation in exfoliation time.
Difficult to determine the cause of missing.
23. Mixed dentition
The caries indices for permanent teeth and
deciduous teeth have to be done separately.
DMFT or DMFS and deft or defs are never
added together
24. Dental caries severity classification
scale (D1-D3)
first published by WHO in 1979.
As an aid to diagnosing coronal caries.
Of extreme value in research studies, why?
This index requires subjects teeth be dried prior
to the examination.
25. 0 : sound surface.
D1 : initial caries, no clinically detectable loss of substance.
D2 : enamel caries, loss of tooth substance but no softened floor
D3 : caries of dentin softened floor, undermined enamel, or tf.
D4 : pulpal involvement, pulp should not be probed
D4 usually included with D3 in data analysis
26. Root caries index (RCI)
Introduced by Katz in 1979.
Only teeth with gingival recession are examined,
because only the root surface that exposed to
the oral environment are at risk to develop root
caries.
RCI records as follow:
27. (R-D) + (R-F )
RCI = X 100
(R-D) + (R-F) + (R-N)
R-D is number of root surfaces that decayed
R-F is number of root surfaces that filled
R-N is number of sound root surfaces
